名词可以分为专有名词（Proper Nouns）和普通名词 (Common Nouns），专有名词是某个（些）人，地方，机构等专有的名称，如Beijing，China等。普通名词是一类人或东西或是一个抽象概念的名词，如：book，sadness等。普通名词又可分为下面四类： 1）个体名词（Individual Nouns）：表示某类人或东西中的个体，如：gun。 2）集体名词（Collective Nouns）：表示若干个个体组成的集合体，如：family。 3）物质名词（Material Nouns）：表示无法分为个体的实物，如：air。 4）抽象名词（Abstract Nouns）：表示动作、状态、品质、感情等抽象概念，如：work。 个体名词和集体名词可以用数目来计算，称为可数名词（Countable Nouns），物质名词和抽象名词一般无法用数目计算，称为不可数名词（Uncountable Nouns）。 归纳表格如下 | |专有名词 | | | 名 | | 个体名词 | | | | | | 可数名词 | | | | 集体名词 | | | |普通名词 | | | | 词 | | 物质名词 | | | | | | 不可数名词| | | | 抽象名词 | | 1.2名词复数的规则变化(P5)? ___________________________________________________ 情况 构成方法 读音 例词 __________________________________________________ 一般情况 加 -s 1.清辅音后读/s/; map-maps 2.浊辅音和元音后 bag-bags 读 /z/; car-cars ___________________________________________________ 以s,sh,ch, x等结尾的词 加 -es 读 /iz/ bus-buses watch-watches ___________________________________________________ 以ce,se,ze, (d)ge等结尾 的词 加 -s 读 /iz/ license-licenses ___________________________________________________ 以辅音字母+y 变y 为i 结尾的词 再加es 读 /z/ baby---babies) 以y 1结尾的专有名词，或元音字母+y 结尾的名词变复数时， 直接加s变复数： 如： two Marys the Henrys monkey---monkeys holiday---holidays 比较： 层楼：storey ---storeys story---stories 2) 以o 结尾的名词，变复数时： a. 加s，如： photo---photos piano---pianos radio---radios zoo---zoos； b. 加es，如：potato--potatoes tomato--tomatoes c. 均可，如：zero---zeros / zeroes 3) 以f或fe 结尾的名词变复数时： a. 加s，如： belief---beliefs roof---roofs safe---safes gulf---gulfs； b. 去f,fe 加ves，如：half---halves knife---knives leaf---leaves wolf---wolves wife---wives life---lives thief---thieves； c. 均可,如： handkerchief: handkerchiefs / handkerchieves 名词复数的不规则变化 ? 1）child---children foot---feet tooth---teeth mouse---mice man---men woman---women 注意：与 man 和 woman构成的合成词，其复数形式也是 -men 和-women。 如： an Englishman，two Englishmen. 但German不是合成词，故复数形式为Germans；Bowman是姓，其复数是the Bowmans。
2）单复同形 如： deer，sheep，fish，Chinese，Japanese li，jin，yuan，two li，three mu，four jin 但除人民币元、角、分外，美元、英镑、法郎等都有复数形式。如: a dollar, two dollars; a meter, two meters
3）集体名词，以单数形式出现，但实为复数。 如：staff people police cattle 等本身就是复数，不能说a staff a people，a police，a cattle，但可以说 a person，a policeman，a head of cattle, the English，the British，the French，the Chinese，the Japanese，the Swiss 等名词，表示国民总称时，作复数用。 如： The Chinese are industries and brave. 中国人民是勤劳勇敢的。 不规则变化4）以s结尾，仍为单数的名词，如： a. maths，politics，physics等学科名词，为不可数名词，是单数。 b. news 是不可数名词。 c. the United States，the United Nations 应视为单数。 The United Nations was organized in 1945. 联合国是1945年组建起来的。 d. 以复数形式出现的书名，剧名，报纸，杂志名，也可视为单数。 "The Arabian Nights" is a very interesting story-book. <<一千零一夜>>是一本非常有趣的故事书。 5) 表示由两部分构成的东西，如：glasses (眼镜) trousers, clothes 若表达具体数目，要借助数量词 pair(对，双); suit(套); a pair of glasses; two pairs of trousers 6） 另外还有一些名词，其复数形式有时可表示特别意思，如：goods货物，waters水域，fishes（各种）鱼
1.3不可数名词量的变化物质名词 a. 当物质名词转化为个体名词时。 比较： Cake is a kind of food. 蛋糕是一种食物。 (不可数) These cakes are sweet. 这些蛋糕很好吃。 (可数) b. 当物质名词表示该物质的种类时，名词可数。 This factory produces steel. (不可数) We need various steels. (可数) c. 当物质名词表示份数时，可数。 Our country is famous for tea. 我国因茶叶而闻名。 Two teas, please. 请来两杯茶。 2） 抽象名词有时也可数。 four freedoms 四大自由 the four modernizations四个现代化 物质名词和抽象名词可以借助单位词表一定的数量。 如： a glass of water 一杯水 a piece of advice 一条建议 1.4复合名词的复数形式(P9)略1.5 名词作定语
名词作定语一般用单数，但也有以下例外。 1) 用复数作定语。 如：sports meeting 运动会 students reading-room 学生阅览室 talks table 谈判桌 the foreign languages department 外语系 2) man, woman, gentleman等作定语时，其单复数以所修饰的名词的单复数而定。 如：men workers women teachers gentlemen officials 3) 有些原有s结尾的名词，作定语时，s保留。 如：goods train (货车) arms produce 武器生产 customs papers 海关文件 clothes brush衣刷
4) 数词+名词作定语时，这个名词一般保留单数形式。 如：two-dozen eggs 两打/（二十四个鸡蛋) a ten-mile walk 十里路 two-hundred trees 两百棵树 a five-year plan 一个五年计划 1.6名词的格在英语中有些名词可以加’s来表示所有或所属关系，带这种词尾的名词形式称为该名词的所有格，如：a teacher’s book。名词所有格的规则如下：（修饰有生命的名词用’s，无生命的一般用of结构）
1） 单数名词词尾加 ’s，复数名词词尾没有s，也要加‘s，如the boy’s bag 男孩的书包，men‘s room 男厕所。
专有名词s结尾（一般应加’s）Charles’s job 2） 若名词已有复数词尾-s ，只加’s，如：the workers' struggle 工人的斗争。 3） 凡不能加"'s"的名词，都可以用"名词+of +名词"的结构来表示所有关系，如：the title of the song 歌的名字。 4） 在表示店铺或教堂的名字或某人的家时，名词所有格的后面常常不出现它所修饰的名词，如：the barber's 理发店。 5） 如果两个名词并列，并且分别有's，则表示"分别有"；只有一个's，则表示'共有'。 如：John's and Mary's room（两间） John and Mary's room（一间） 6） 复合名词或短语，'s 加在最后一个词的词尾。 如：a month or two's absence 双重所有格（of+’s的两种结合）P11-13 (textbook)

作业
列出有关名词一讲疑惑不解或易错的５－１０个难点．第二讲 冠词和数词 冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义。英语中的冠词有三种，一种是定冠词（the Definite Article），另一种是不定冠词（the Indefinite Article），还有一种是零冠词（Zero Article）。
２.1不定冠词的用法 不定冠词a (an)与数词one 同源，是"一个"的意思。a用于辅音音素前，一般读作[e]，而an则用于元音音素前，一般读做[en]。 1) 表示"一个"，意为one；指某人或某物，意为a certain。 A Mr. Ling is waiting for you. 2) 代表一类人或物。 A knife is a tool for cutting with. Mr. Smith is an engineer. 3) 词组或成语。 a little / a few / a lot / a type of / a pile / a great many / many a / as a rule / in a hurry / in a minute / in a word / in a short while / after a while / have a cold / have a try / keep an eye on / all of a sudden 2.2定冠词的用法定冠词the与指示代词this，that同源，有"那（这）个"的意思，但较弱，可以和一个名词连用，来表示某个或某些特定的人或东西。 1）特指双方都明白的人或物： Take the medicine. 把药吃了。 2）上文提到过的人或事： He bought a house. I've been to the house. 他买了幢房子。我去过那幢房子。 3）指世上独一物二的事物： the sun， the sky， the moon， the earth 4）单数名词连用表示一类事物，如：the dollar 美元; the fox 狐狸；或与形容词或分词连用，表示一类人：the rich 富人; the living 生者。 5）用在序数词和形容词最高级，及形容词only， very， same等前面： Where do you live? I live on the second floor. 你住在哪？我住在二层。 That's the very thing I've been looking for. 那正是我要找的东西。 6）与复数名词连用，指整个群体： They are the teachers of this school.指全体教师) They are teachers of this school. (指部分教师) 7）表示所有，相当于物主代词，用在表示身体部位的名词前： She caught me by the arm.. 她抓住了我的手臂。 8）用在某些由普通名词构成的国家名称、机关团体、阶级、等专有名词前： the People's Republic of China 中华人民共和国 the United States 美国 9）用在表示乐器的名词之前： She plays the piano. 她会弹钢琴。 10) 用在姓氏的复数名词之前，表示一家人： the Greens 格林一家人 (或格林夫妇) 11) 用在惯用语中： in the day, in the morning (afternoon，evening), the day after tomorrow the day before yesterday, the next morning, in the sky (water，field，country) in the dark, in the rain, in the distance, in the middle (of), in the end, on the whole, by the way, go to the theatre 2.3零冠词1) 国名，人名前通常不用定冠词：England，Mary； 2）泛指的复数名词，表示一类人或事物时，可不用定冠词； They are teachers. 他们是教师。 3）抽象名词表示一般概念时，通常不加冠词； Failure is the mother of success. 失败乃成功之母。 4）物质名词表示一般概念时，通常不加冠词，当表示特定的意思时，需要加定冠词； Man cannot live without water. 人离开水就无法生存。 5）在季节、月份、节日、 假日、日期、星期等表示时间的名词之前，不加冠词； We go to school from Monday to Friday. 我们从星期一到星期五都上课。 6）在称呼或表示官衔，职位的名词前不加冠词； The guards took the American to General Lee. 士兵们把这个美国人送到李将军那里。
7）在三餐、球类运动和娱乐运动的名称前，不加冠词 如:
have breakfast，play chess
8）当两个或两个以上名词并用时，常省去冠词； I can‘t write without pen or pencil.没有钢笔和铅笔，我就写不了字.
9）当by 与火车等交通工具连用，表示一种方式时，
中间无冠词；by bus，by train；
10）有些个体名词不用冠词；如： school，college，prison，market，hospital，bed，table，class，
town，church，court 等个体名词，直接置于介词后，表示该名词的深层含义（某种行为）； go to hospital 去医院看病 go to the hospital 去医院 (并不是去看病，而是有其他目的)
11)不用冠词的序数词； a. 序数词前有物主代词 b. 序数词作副词 He came first in the race. c. 在固定词组中 at (the) first, first of all, from first to last
(p21-22) 2.4冠词与形容词+名词结构 1) 两个形容词都有冠词，表示两个不同东西。 He raises a black and a white cat. 他养了一只黑猫和一只白猫。 The black and the white cats are hers. 这只黑猫和白猫都是他的。 2) 如后一个形容词无冠词，则指一物。 He raises a black and white cat. 他养了一只花猫。 2.5冠词位置 1) 不定冠词位置 不定冠词常位于名词或名词修饰语前。注意： a. 位于下列形容词之后： such，what，many，half， I have never seen such an animal. Many a man is fit for the job. b. 当名词前的形容词被副词as, so, too, how, however, enough修饰时，不定冠词应放在形容词之后： It is as pleasant a day as I have ever spent. So short a time. Too long a distance.
c. quite，rather与单数名词连用，冠词放在其后。 但当rather，quite 前仍有形容词，不定冠词放其前后均可。如：quite a lot d. 在as，though 引导的让步状语从句中，当标语为形容
词修饰的名词时不定冠词放形容词后： Brave a man though he is，he trembles at the
sight of snakes.
他尽管勇敢，可见到蛇还是发抖。 当名词被比较级形容词修饰时，不定冠词通常置于比较级
形容词之后。 2) 定冠词位置 定冠词通常位于名词或名词修饰语前，但放在all， both，
double，half，twice，three times等词之后，名词之前。 All the students in the class went out.
班里的所有学生都出去了。 2.6数词(P69-77)
表示数目多少或顺序多少的词叫数词，数词分为基数词和序数词。表示数目多少的数词叫基数词；表示顺序的数词叫序数词。
一、基数词 1）基数词写法和读法： 345 three hundred and forty-five； 2）基数词一般是单数形式，但下列情况，常用复数： a. 与of 短语连用，表示概数，不能与具体数目连 用，如scores of people 指许多人； b. 在一些表示"一排"或"一组"的词组里； 如：They arrived in twos and threes. 他们三三两两的到达了。 c. 表示"几十岁"； d. 表示"年代"，用 in +the +数词复数； e. 在乘法运算的一种表示法里，如：3 x 5 = 15

第三讲 代词
3.1人称代词分类
代词是代替名词的一种词类。大多数代词具有名词和形容词的功能。英语中的代词，按其意义、特征及在句中的作用分为：人称代词、物主代词、指示代词、自身代词、相互代词、疑问代词、关系代词和不定代词八种。 一、人称代词是表示“我”、“你”、“他”、“她”、“它”、 我们"、"你们"、"他们"的词。人称代词有人称、数和格的变下表： 数 单数 复数 格 主格 宾格 主格 宾格 第一人称 I me we us 第二人称 you you you you he him they them 第三人称 she her they them it it they them 如：He is my friend. 他是我的朋友。 It's me. 是我。
二、 物主代词表示所有关系的代词，也可叫做代词所有格。
物主代词分形容性物主代词和名词性物主代词二种，其人物和数
的变化见下表。 数 单数 复数 人称 第一 第二 第三 第一 第二 第三 人称 人称 人称 人称 人称 人称 形容词性 my your his/her its our your/their 物主代词 名词性 mine yours his/hers its ours yours/theirs 物主代词
如： I like his car. 我喜欢他的小汽车。
Our school is here，and theirs is there. 我们的学校在这儿，他们的在那儿。 三、 指示代词表示“那个”、“这个”、“这些”、“那些”等指示概念的代词。
指示代词有this，that，these，those等。 如： That is a good idea. 那是个好主意。
四、 表示“我自己”、“你自己”、“他自己”、“我们自己”、“你们自己
”和“他们自己”等的代词，叫做自身代词，也称为“反身代词”。 如： She was talking to herself. 她自言自语。
五、 表示相互关系的代词叫相互代词，有each other 和one another两组，但在运用中，这两组词没什么区别。 如： They love each other. 他们彼此相爱。 六、 不是指明代替任何特定名词的代词叫做不定代词。常见的不定代词有a11，both，each，every等，以及含有some-，any-，no-等的合成代词，如anybody， something，no one。这些不定代词大都可以代替名词和形容词，在句中作主语、宾语、表语和定语， 但none和由some，any，no等构成的复合不定代词只能作主语、宾语或表语；every和no只能作定语。如： --- Do you have a car? --你有一辆小汽车吗？ --- Yes，I have one. --是的，我有一辆。 --- I don't know any of them. 他们，我一个也不认识。 七、 疑问代词有who，whom，whose，what和which等。在句子中用来构成特殊疑问句。疑问代词都可用作连接代词，引导名词性从句（主语从句、宾语从句和表语从句） 如：Tell me who he is. 告诉我他是谁。 八、 关系代词有who，whom，whose，that，which，as等，可用作引导从句的关联词。它们在定语从句中可作主语、表语、宾语、定语等；另一方面它们又代表主句中为定语从句所修饰的那个名词或代词（通称为先行词）。 如： He is the man whom you have been looking for. 他就是你要找的那个人。 3.2人称代词的用法(P28-31)Let’s与 let us 有时有异义．Let’s多用来表劝告或建议，包括自己与对方在内．
Let’s go, shall we?
Let’s start at once.
在不包括对方的情况下，须用Let us
Please let us know the time of your arrival.
Please let us buy you a drink.3.3并列人称代词的排列顺序 1) 单数人称代词并列作主语时，其顺序为： 第二人称 －> 第三人称 －> 第一人称 you －> he/she; it -> I You, he and I should return on time. 2) 复数人称代词作主语时，其顺序为： 第一人称 －> 第二人称 －> 第三人称 we －> you －> They 注意： 在下列情况中，第一人称放在前面。 a. 在承认错误，承担责任时， It was I and John that made her angry. 是我和约翰惹她生气了。 b. 在长辈对晚辈，长官对下属说话时，如长官为第一人称， 如：I and you try to finish it. c. 并列主语只有第一人称和第三人称时， d. 当其他人称代词或名词被定语从句修饰时。 3.4物主代词 (P32-34)形容词性
名词性3.5双重所有格物主代词不可与 a, an, this, that, these, those, some, any, several, no, each, every, such, another, which等词一起前置，修饰一个名词，而必须用双重所有格。 公式为： a, an, this, that +名词+of +名词性物主代词。如： a friend of mine. each brother of his. 3.6反身代词1） 列表 I you you she he myself yourself yourselves herself himself we they it one ourselves themselves itself oneself 2）做宾语 a. 有些动词需有反身代词 absent, bathe, amuse, blame, dry, cut, enjoy, hurt, introduce, behave We enjoyed ourselves very much last night. 我们昨晚玩得很开心。 Please help yourself to some fish. 请你随便吃点鱼。 b. 用于及物动词+宾语+介词 take pride in, be annoyed with, help oneself to sth. I could not dress (myself) up at that time. 那个时候我不能打扮我自己。 注：有些动词后不跟反身代词， get up, sit-down, stand up, wake up等。 Please sit down. 请坐。
3） 作表语； 同位语 be oneself: I am not myself today. 我今天不舒服。 The thing itself is not important. 事情本身并不重要。 4） 在不强调的情况下，but, except, for 等介词后宾语用反身代词或人称代词宾格均可。如： No one but myself (me) is hurt. 注意： a. 反身代词本身不能单独作主语。 (错) Myself drove the car. (对) I myself drove the car. 我自己开车。 b. 但在and, or, nor连接的并列主语中，第二个主语可用反身代词，特别是myself 作主语。 Charles and myself saw it. 5）第二人称作宾语，要用反身代词。 You should be proud of yourself. 你应为自己感到骄傲。 习惯用法(P35-37)textbook

(p37-38)3.8指示代词和疑问代词１．指示代词(such; so; same)的用法
P40-48
２．疑问代词 P48-513.9关系代词 1） 关系代词用来引导定语从句。它代表先行词，同时在从句中作一定的句子成分，例如：The girl to whom I spoke is my cousin. 跟我讲话的姑娘是我表妹。（该句中whom既代表先行词the girl，又在从句中作介词to的宾语。） 2） 关系代词有主格，宾格和属格之分，并有指人与指物之分。在限定性定语从句中，that 可指人也可指物，见表： 限定性 非限定性 限定性 指 人 指 物 指人或指物 主 格 who which that 宾 格 whom that that 属 格 whose of which/whose of which/whose 例如： This is the pencil whose point is broken. 这就是那个折了尖的铅笔。 (whose 指物，在限定性定语从句中作定语) He came back for the book which he had forgotten. 他回来取他丢下的书。 （which指物，在限定性定语从句中作宾语，可以省略） 3） 关系代词which的先行词可以是一个句子，例如： He said he saw me there, which was a lie. 他说在那儿看到了我，纯属谎言。 说明： 关系代词that在从句中作宾语或表语时可省略， 例如： I've forgotten much of the Latin I once knew. 我过去懂拉丁语，现在大都忘了。 He's changed. He's not the man he was. 他变化很大，已不是过去的他了。 3.10不定代词every , no, all, both, neither, nor? 1）不定代词有 all , both, every, each, either, neither, more, little, few, much, many, another, other, some, any , one, no 以及some, something, anything, everything, somebody, someone, anybody, anyone, nothing , nobody, no one, none, everybody, everyone.等。 2） 不定代词的功能与用法 a. 除every 和no外不定代词既可用作名词，也可用作形容词。every和no在句中只能作定语。 I have no idea about it. b. all 都，指三者以上。 all 的主谓一致：all的单复数由它所修饰或指代的名词的单复数决定。 All goes well. 一切进展得很好。 all 通常不与可数名词单数连用，如：不说 all the book，而说 the whole book。 但all可与表时间的可数名词单数连用，如 all day，all night，all the year； 但习惯上不说 all hour，all century。 all还可以与一些特殊的单数名词连用，如 all China， all the city， all my life， all the way 3) both 都，指两者。 a. both 与复数动词连用，但 both… and…可与单数名词连用。 b. both, all 都可作同位语，其位置在行为动词前， be 动词之后。如果助动词或情态动词后面的实义动词省 去，则位于助动词或情态动词之前。 Who can speak Japanese? We both (all) can. . 4) neither 两者都不 a. neither作主语时，谓语动词用单数。 b. 作定语与单数名词连用，但neither… nor 用作并列连词，可与复数名词连用。其谓语采用就近原则。 c. 可用于下列句型，避免重复。 She can't sing，neither (can) he.
neither 与nor d. 如前句是否定式从句，则主句用neither，而不用 nor。 If you don't do it，neither should I. 如果你不干，我也不干。 e. 如后连续有几个否定句式，则用nor，不用neither。 He can't sing，nor dance，nor skate. none, few, some, any, one, ones? 一、 none 无 1) none作主语，多与of 构成短语 none of。 在答语中，none可单独使用。 Are there any pictures on the wall? None. 2) none作主语，谓语动词单复数均可。但如做表语，则其单复数与表语一致。 It is none of your business. 二、few 一些，少数 few 作主语时，谓语动词用复数，多用于肯定句。 三、some 一些 1) 可与复数名词及不可数名词连用。 2) 当做"某一"解时，也可与单数名词连用。（= a certain） You will be sorry for this some day. 总有一天，你会后悔这件事的。 A certain (some) person has seen you break the rule. 某些人不同意你的看法。 注意： (1)在肯定疑问句中用some代替any。 (2)some用于其他句式中: a. 肯定疑问句中：说话人认为对方的答案会是肯定的，或期望得到肯定回答时。 Would you like句式中，表委婉请求或建议，如： Would you like some coffee? b. 在条件状语从句中表示确定的意义时，如： If you need some help，let me know. c. some位于主语部分, Some students haven't been there before d. 当否定的是整体中的部分时，some可用于否定句。如： I haven't heard from some of my old friends these years. 这些年我没有收到一些老朋友的信。 四、any 一些 1) any 多用于否定句和疑问句和条件状语从句中。 当句中含有任何的意思时，any可用于肯定句。 Here are three novels. You may read any. 这有三本小说，你可任读一本。 五、one, ones 为复数形式 ones必须和形容词连用。如果替代的名词时无形容词在前，则用some, any，而不 用ones。 Have you bought any rulers? Yes，I 've bought some. ? 代词比较辩异 one，that 和it?
one表示泛指，that和it 表示特指。that与所指名词为同类，但不是同一个，而it 与所指名词为同一个。 I can't find my hat. I think I must buy one. (不定) 我找不到我的帽子了。我想我该去买一顶。 The hat you bought is bigger than that I bought. (同类但不同个) 你买的那顶帽子比我买的大。 I can't find my hat. I don' t know where I put it. ( 同一物) 我找不到我的帽子。我不知道我把它放在哪了。 one/another/the other
? one… the other 只有两个 some… the others 有三个以上 one… another，another… some… others，others… others = other people/things the others = the rest 剩余的全部 1) 泛指另一个用another。 2) 一定范围内两人(物)，一个用one，另一个用the other。 3) 一定范围内三者，一个用one，另一个用one (another)，第三个可用the other，a third。 4) 一定范围内，除去一部分人/物，剩余的全部用the others。 5) 泛指别的人或物时，用others当在一定范围内，除去一部分后，剩余部分但不是全部时，也用others。 both, either, neither, all, any, none?
这些词都可用作代词或形容词。其位置都在be 动词之后，行为动词之前或第一助动词之后。 1) both (两者都)，either(两者中任何一个)， neither (两者都不)。以上词使用范围为两个人或物。 Neither of the two boys is clever. 两个男孩都不聪明。 2) both，either both与复数连用，either与单数连用。 Both the boys are clever. 两个男孩都很聪明。 Either of the two boys is clever. 两个男孩都很聪明。 There are flowers on both sides of the street. (两岸) There are flowers on either side of the street. (岸的两边) 路边长满了野花。 3) all (所有的，全部的人或物)，any (任何一个)， none (都不)。 以上词使用范围为三者以上。 All the flowers are gone. 所有的花都谢了。 I don't like any of the flowers. 这些花我都不喜欢。 I like none of the flowers. 这些花我都不喜欢。 注意：all与none用法一样。跟单数名词，用单数动词；跟复数名词，用复数动词。 All of the students are there. 所有的学生都在那。 All (of) the milk is there. 所有的牛奶都在那。 few, little, a few, a little (a) few + 可数名词, (a) little + 不可数名词 a few / a little 为肯定含义，还有一点 few / little 为否定含义，没有多少了。 He has a few friends. 他有几个朋友。 He has few friends. 他几乎没有朋友。 We still have a little time. 我们还有点时间。 There is little time left.几乎没剩下什么时间了。 典型例题: Although he 's wealthy，he spends___ on clothes. A. little B. few C. a little D. a few 答案： A. spend所指的是钱，不可数，只能用little或 a little. 本句为although引导的让步状语从句，由句意知后句为否定含义，因此应用little表示几乎不。 固定搭配: only a few (=few) not a few (=many) quite a few (=many) many a (=many) Many books were sold. Many a book was sold. 卖出了许多书。 第四讲 动词的时态概念（时间与时态）
时态是一种语言的手段，因语言的不同而有区别。英语时态以动词形式变化表示句中谈到的动作、状态的时间关系和说话的时间。（十一种）P79表格
1 一般现在时的用法?
1) 经常性或习惯性的动作，常与表示频腮度的时间状语连用。 时间状语： every…, sometimes, at…, on Sunday I leave home for school at 7 every morning. 2) 客观真理，客观存在，科学事实。 The earth moves around the sun. Shanghai lies in the east of China. 3) 表示格言或警句中。 Pride goes before a fall. 骄者必败。 注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。 例：Columbus proved that the earth is round.. 4) 现在时刻的状态、能力、性格、个性。 I don't want so much. Ann Wang writes good English but does not speak well. 比较：Now I put the sugar in the cup. I am doing my homework now. 第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。
现在进行时?4.2.1现在进行时的基本用法： a. 表示现在( 指说话人说话时) 正在发生的事情。 We are waiting for you. b. 习惯进行：表示长期的或重复性的动作，说话时动作未必正在进行。 Mr. Green is writing another novel. (说话时并未在写，只处于写作的状态。) She is learning piano under Mr. Smith. c. 表示渐变的动词有：get, grow, become, turn, run, go, begin等。 The leaves are turning red. It's getting warmer and warmer. d. 与always, constantly, forever 等词连用，表示反复发生的动作或持续存在的状态，往往带有说话人的主观色彩。 You are always changing your mind. 典型例题 My dictionary ___, I have looked for it everywhere but still___ it. A. has lost, don‘t find B. is missing, don’t find C. has lost, haven‘t found D. is missing, haven’t found. 答案D. 前句是一个仍在持续的状态，应用进行时，由于没有找到，其影响仍然存在，应用完成时，瞬间动词用于否定式时可用于完成时。
2.不用进行时的动词?
1) 事实状态的动词 have, belong, possess, cost, owe, exist, include, contain, matter, weigh, measure, continue I have two brothers. This house belongs to my sister. 2) 心理状态的动词 Know, realize, think see, believe, suppose, imagine, agree, recognize, remember, want, need, forget, prefer, mean, understand, love, hate I need your help. He loves her very much. 3 ) 瞬间动词 accept, receive, complete, finish, give, allow, decide, refuse. I accept your advice. 4) 系动词 seem, remain, lie, see, hear, smell, feel, taste, get, become, turn You seem a little tired.
4.3一般过去时1）在确定的过去时间里所发生的动作或存在的状态。 时间状语有：yesterday, last week, an hour ago, the other day, in 1982等。 Where did you go just now? 2）表示在过去一段时间内，经常性或习惯性的动作。 When I was a child, I often played football in the street. Whenever the Browns went during their visit, they were given a warm welcome. 3）句型： It is time for sb. to do sth "到……时间了" "该……了" It is time sb. did sth. "时间已迟了" "早该……了" It is time for you to go to bed. 你该睡觉了。 It is time you went to bed. 你早该睡觉了。 would (had) rather sb. did sth. 表示'宁愿某人做某事' I'd rather you came tomorrow. 4) wish, wonder, think, hope 等用过去时，作试探性的询问、请求、建议等。 I thought you might have some. 我以为你想要一些。 比较： 一般过去时表示的动作或状态都已成为过去，现已不复存在。 Christine was an invalid all her life. (含义：她已不在人间。) Christine has been an invalid all her life. (含义：她现在还活着) Mrs. Darby lived in Kentucky for seven years. (含义：达比太太已不再住在肯塔基州。) Mrs. Darby has lived in Kentucky for seven years. ( 含义：现在还住在肯塔基州，有可能指刚离去) 注意： 用过去时表示现在，表示委婉语气。 1）动词want, hope, wonder, think, intend 等。 Did you want anything else? I wondered if you could help me. 2）情态动词 could, would. Could you lend me your bike?
4.4过去进行时（P108 略）4.5现在完成时
1现在完成时用来表示之前已发生或完成的动作或状 态，其结果的确和现在有联系。动作或状态发生在过去 但它的影响现在还存在；也可表示持续到现在的动作或 状态。其构成： have (has) +过去分词。
(2)用于现在完成时的句型 ?
1）It is the first / second time…. that…结构中的从句部分，用现在完成时。 It is the first time that I have visited the city. It was the third time that the boy had been late. 2）This is the… that…结构，that 从句要用现在完成时. This is the best film that I've (ever) seen. 这是我看过的最好的电影。 This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。
典型例题 (1) ---Do you know our town at all? ---No, this is the first time I ___ here. A. was B. have been C. came D. am coming 答案B. This is the first time 后面所加从句应为现在完成时，故选B。
2) ---Have you ____ been to our town before? ---No, it's the first time I ___ here. A. even, come B. even, have come C. ever, come D. ever, have come 答案D. ever意为曾经或无论何时，反意词为never，此两词常用于完成时。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中，从句要用完成时。 注意：非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。 （错）I have received his letter for a month. （对）I haven't received his letter for almost a month.
3比较过去时与现在完成时?
1）过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。 2）过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。 一般过去时的时间状语: yesterday, last week，…ago, in1980, in October, just now, 具体的时间状语 共同的时间状语: this morning, tonight,this April, now, once，before, already, recently，lately 现在完成时的时间状语 for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always, 不确定的时间状语
3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know. 过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。 举例： I saw this film yesterday. （强调看的动作发生过了。） I have seen this film. （强调对现在的影响，电影的内容已经知道了。） Why did you get up so early? （强调起床的动作已发生过了。） Who hasn‘t handed in his paper? （强调有卷子，可能为不公平竞争。） She has returned from Paris. 她已从巴黎回来了。 She returned yesterday. 她是昨天回来了。 He has been in the League for three years. (在团内的状态可延续) He has been a League member for three years. (是团员的状态可持续)
He joined the League three years ago. ( 三年前入团，joined为短暂行为。) I have finished my homework now. ---Will somebody go and get Dr. White? ---He's already been sent for. 句子中如有过去时的时间副词（如 yesterday, last, week, in 1960）时，不能使用现在完成时，要用过去时。 （错）Tom has written a letter to his parents last night. （对）Tom wrote a letter to his parents last night.
4比较since和for?
Since 用来说明动作起始时间，for用来说明动作延续时间长度。 I have lived here for more than twenty years. I have lived here since I was born.. My aunt has worked in a clinic since 1949. Some new oilfields have been opened up since 1976. I have known Xiao Li since she was a little girl. My brother has been in the Youth League for two years. I have not heard from my uncle for a long time. 注意：并非有for 作为时间状语的句子都用现在完成时。 I worked here for more than twenty years. (我现在已不在这里工作。) I have worked here for many years. (现在我仍在这里工作。)
小窍门： 当现在完成时+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。 1) (对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now. 2) (错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now. 显然，第二句不对，它应改为 Harry got married six years ago. 或 Harry has been married for six years. 5.延续动词与瞬间动词?
1) 用于完成时的区别 延续动词表示经验、经历； 瞬间动词表示行为的结 果，不能与表示段的时间状语连用。 He has completed the work. 他已完成了那项工作。 (表结果) I‘ve known him since then. 我从那时起就认识他了。(表经历) 2) 用于till / until从句的差异 延续动词用于肯定句，表示“做……直到……” 瞬间动词用于否定句，表示“到……，才……” He didn’t come back until ten o‘clock. 他到10 点才回来。 He slept until ten o’clock. 他一直睡到10点。
4.5 将来一般时1.用法
1) shall用于第一人称，常被will 所代替。 will 在陈述句中用于各人称，在争求意见时常用于第二人称。 Which paragraph shall I read first. Will you be at home at seven this evening? 2) be going to +不定式，表示将来。 a. 主语的意图，即将做某事。 What are you going to do tomorrow? b. 计划，安排要发生的事。 The play is going to be produced next month。 c. 有迹象要发生的事 Look at the dark clouds, there is going to be a storm. 3) be +不定式表将来，按计划或正式安排将发生的事。 We are to discuss the report next Saturday. 4) be about to +不定式，意为马上做某事。 He is about to leave for Beijing. 注意：be about to 不能与tomorrow, next week 等表示明确将来时的时间状语连用。
2.be going to / will?
用于条件句时， be going to 表将来 will 表意愿 If you are going to make a journey, you'd better get ready for it as soon as possible. Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.
3.be to和be going to ?
be to 表示客观安排或受人指示而做某事。 be going to 表示主观的打算或计划。 I am to play football tomorrow afternoon. (客观安排) I‘m going to play football tomorrow afternoon. (主观安排)
4.6过去完成时过去完成时?
1） 概念：表示过去的过去 ----|-------|-----|---->其构成是had +过去分词构成。 那时以前 那时 现在 2） 用法 a. 在told, said, knew, heard, thought等动词后的宾语从句。 She said (that) she had never been to Paris. b. 状语从句 在过去不同时间发生的两个动作中，发生在先，用过去完成时；发生在后，用一般过去时。 When the police arrived, the thieves had run away. c. 表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本…，未能…" We had hoped that you would come, but you didn't.
3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。 He said that he had learned some English before. By the time he was twelve, Edison had began to make a living by himself. Tom was disappointed that most of the guests had left when he arrived at the party. 典型例题 The students ___ busily when Miss Brown went to get a book she ___ in the office. A. had written, left B，were writing, has left C. had written, had left D. were writing, had left 答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前，因此"忘了书"这一动作发生在过去的过去，用过去完成时。句中when表示的是时间的一点，表示在"同学们正忙于……"这一背景下，when所引导的动作发生。因此 前一句应用过去进行时。 注意： had no … when 还没等…… 就…… had no sooner… than 刚…… 就…… He had no sooner bought the car than he sold it.
4.7时态一致?
1) 如果从句所叙述的为真理或不变的事实，则永远用现在时。 At that time, people did not know that the earth moves. He told me last week that he is eighteen. 2) 宾语从句中的助动词ought, need, must, dare 时态是不变的。 He thought that I need not tell you the truth.
4.8 时态与时间状语?
时间状语 一般现在时 every …, sometimes, at …, on Sunday, 一般过去时 yesterday, last week, an hour ago, the other day, in 1982, just now 一般将来时 next…, tomorrow, in+时间, 现在完成时 for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always, recently
过去完成时 before, by, until, when, after, once, as soon as 过去进行时 this morning, the whole morning, all day, yesterday, from nine to ten last evening… when, while 将来进行时 soon, tomorrow, this evening, on Sunday, by this time, tomorrow, in two days, tomorrow evening
第五讲 动词语态动词的语态?
语态有两种：主动语态和被动语态。 主语是动作的发出者为主动语态；The cat caught the mouse.
主语是动作的接受者为被动语态。The mouse was caught by the mouse
被动语态构成形式：用于常用的七种时态。（p114-116)
1）若宾语补足语是不带to 的不定式，变为被动语态时，该不定式前要加"to"。此类动词为感官动词。 feel, hear, help, listen to, look at, make, observe, see, notice, watch The teacher made me go out of the classroom. --> I was made to go out of the classroom (by the teacher). We saw him play football on the playground. --> He was seen to play football on the playground. 2）情态动词+ be +过去分词，构成被动语态。 Coal can be used to produce electricity for agriculture and industry.
3.表示"据说"或"相信" 的词组?
believe, consider, declare, expect, feel , report, say, see, suppose, think, understand It is said that… 据说 It is reported that… 据报道 It is believed that… 大家相信 It is hoped that… 大家希望 It is well known that… 众所周知 It is thought that… 大家认为 It is suggested that… 据建议 It is taken granted that… 被视为当然 It has been decided that… 大家决定 It must be remember that…务必记住的是 It is said that she will leave for Wuhan on Tuesday.
4.be supposed to
1. be said to 据说
He is supposed to have stolen $1,000.
2. 计划，安排
The train was supposed to arrive at 11:30, but it was 40 minutes late.
3. be not supposed to 表示不允许等
You’re not supposed to park here.
5. 动词get代替be
There was a fight at the pub, but fortunately nobody got hurt.
Did any of these houses get damaged in the storm last night?
第六讲 情态动词6.1 情态动词的语法特征 1） 情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。 2） 情态动词 除ought 和have 外，后面只能接不带to 的不定式。 3） 情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。 4） 情态动词没有非谓语形式，即没有不定式，分词，等形式
6.2 比较can 和be able to?
1）can could 表示能力；可能 (过去时用could), 只用于现在式和过去式(could)。be able to可以用于各种时态。 They will be able to tell you the news soon. 他很快就能告诉你消息了。 2）只用be able to a. 位于助动词后。 b. 情态动词后。 c. 表示过去某时刻动作时。 d. 用于句首表示条件。 e. 表示成功地做了某事时，只能用was/were able to， 不能用could
He was able to flee Europe before the war broke out. = He managed to flee Europe before the war broke out. 注意：could不表示时态 1）提出委婉的请求，（注意在回答中不可用could）。 --- Could I have the television on? --- Yes, you can. / No, you can't. 2）在否定，疑问句中表示推测或怀疑。 He couldn't be a bad man. 他不大可能是坏人。
P124
be able to 表示在特定情景中努力做成某事。
The first spread through the building very quickly, but luckily everyone was able to escape.
大火在楼里蔓延，幸好大家都及时撤离了。（在此不能用could ）
They didn’t want to come with us at first, but in the end we were able to persuade them.
起初他们不想与我们一起来，但是最后我们还是说服了他们。（在此不能用could）
6.3 比较may和might ） 表示允许或请求；表示没有把握的推测；may 放在句首，表示祝愿。 May God bless you! He might be at home. 注意： might 表示推测时，不表示时态。只是可能性比may 小。 2） 成语： may/might as well，后面接不带to 的不定式，意为"不妨"。 If that is the case, we may as well try. 典型例题 Peter ___come with us tonight, but he isn't very sure yet. A. must B. may C. can D. will 答案B. 表可能性只能用may. 此句意可从后半句推出。
6.4 比较have to和must 1) 两词都是'必须'的意思，have to 表示客观的需要， must 表示说话人主观上的看法，既主观上的必要。 My brother was very ill, so I had to call the doctor in the middle of the night. 我弟弟病得很厉害，我只得半夜里把医生请来。(客观上需要做这件事) He said that they must work hard. 他说他们必须努力工作。（主观上要做这件事） 2) have to有人称、数、时态的变化，而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。 He had to look after his sister yesterday.
3） 在否定结构中： don‘t have to 表示“不必” mustn’t 表示“禁止”，
You don‘t have to tell him about it. 你不一定要把此事告诉他。 You mustn’t tell him about it. 你一定不要把这件事告诉他。
6.5 must表示推测 1) must用在肯定句中表示较有把握的推测，意为"一定"。 2) must表对现在的状态或现在正发生的事情的推测时， must 后面通常接系动词be 的原形或行为动词的进行式。 You have worked hard all day.You must be tired. 你辛苦干一整天，一定累了。（对现在情况的推测判断） He must be working in his office. 他一定在办公室工作呢。 比较： He must be staying there. 他现在肯定呆在那里。 He must stay there. 他必须呆在那。
3) must 表示对已发生的事情的推测时，must 要接完成式。 I didn't hear the phone. I must have been asleep. 我刚才没有听到电话，我想必是睡着了。 4) must表示对过去某时正发生的事情的推测，must 后面要接不定式的完成进行式。 ---Why didn't you answer my phone call? ---Well, I must have been sleeping, so I didn't hear it. 5) 否定推测用can't。 If Tom didn't leave here until five o'clock, he can't be home yet. 如果汤姆五点才离开这儿，他此时一定还未到家。 6.6 表示推测的用法 can, could, may, might, must 皆可表示推测，其用法如下： 1）情态动词+动词原形。 表示对现在或将来的情况的推测，此时动词通常为系动词。 I don't know where she is, she may be in Wuhan. 2）情态动词+动词现在进行时。 表示对现在或将来正在进行的情况进行推测。 At this moment, our teacher must be correcting our exam papers. 这时，我们老师想必在批改试卷。 3）情态动词+动词完成时。 表示对过去情况的推测。 We would have finished this work by the end of next December. 明年十二月底前我们很可能已完成这项工作了。 The road is wet. It must have rained last night. 地是湿的，昨天晚上一定下雨了。
4）情态动词+动词的现在完成进行时。 表示对过去正在发生事情的推测。 Your mother must have been looking for you. 你妈妈一定一直在找你。 5）推测的否定形式，疑问形式用can't, couldn't表示。 Mike can't have found his car, for he came to work by bus this morning. 迈克一定还没有找回他的车，因为早上他是坐公共汽车来上班的。 注意：could, might表示推测时不表示时态，其推测的程度不如can, may。
6.7 情态动词+ have +过去分词 1) may(might) have + done sth, can (could) have + done sth 表示过去，推测过去时间里可能发生的事情。 Philip may (might) have been hurt seriously in the car accident. Philip can (could) have been hurt seriously in the car accident. 2) must have +done sth，对过去时间里可能发生的事情的推测，语气较强，具有"肯定"，"谅必"的意思。 ---Linda has gone to work, but her bicycle is still here. ---She must have gone by bus. 3) ought to have done sth, should have done sth 本应该做某事，而事实上并没有做。否定句表示"不该做某事而做了"。
You ought to (should) have been more careful in this experiment. He ought not to have thrown the old clothes away.（事实上已扔了。） ought to 在语气上比should 要强。 4) needn't have done sth 本没必要做某事 I dressed very warmly for the trip, but I needn't have done so. The weather was hot. 5) would like to have done sth 本打算做某事 I would like to have read the article, but I was very busy .
6.8 should 和ought to should 和ought to 都为"应该"的意思，可用于各种人称。 ---Ought he to go? ---Yes. I think he ought to. 表示要求，命令时，语气由 should（应该）、had better最好）、must（必须）渐强。
6.9 had better表示"最好" had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。 had better do sth had better not do sth It is pretty cold. You'd better put on my coat. She'd better not play with the dog. had better have done sth表示与事实相反的结果，意为"本来最好"。 You had better have come earlier
.
6.10 would rather表示"宁愿" would rather do would rather not do would rather… than… 宁愿……而不愿。 还有would sooner, had rather, had sooner都表示"宁愿"、"宁可"的意思。 If I have a choice, I had sooner not continue my studies at this school. I would rather stay here than go home. = I would stay here rather than go home. 典型例题 ----Shall we go skating or stay at home? ----Which ___ do? A. do you rather B. would you rather C. will you rather D. should you rather 答案B。本题考查情态动词rather的用法，would rather +do sth 意为"宁愿"，本题为疑问句，would 提前，所以选B
6.11 will和would 注意： 1）would like； Would like to do = want to 想要，为固定搭配。 Would you like to go with me? 2）Will you…? Would you like…? 表示肯定含义的请求劝说时，疑问句中一般用some, 而不是any。 Would you like some cake? 3）否定结构中用will，一般不用would, won't you是一种委婉语气。 Won't you sit down?
6.12 情态动词的回答方式 问句 肯定回答 否定回答 Need you…? Yes, I must. No,I needn't Must you…? /don't have to. 典型例题 1）---Could I borrow your dictionary? ---Yes, of course, you____. A. might B. will C. can D. should 答案C.could表示委婉的语气，并不为时态。答语中of course，表示肯定的语气，允许某人做某事时，用can和 may来表达，不能用could或might。复习： will 与you连用，用来提出要求或下命令。should与you 连用，用来提出劝告。
2）---Shall I tell John about it? ---No, you ___. I've told him already. A. needn't B. wouldn't C. mustn't D. shouldn't
答案A。needn't 不必，不用。 wouldn't 将不, 不会的。 mustn't 禁止、不能。 shouldn't 不应该。本题为不需要，不必的意思，应用needn't。 3）---Don't forget to come to my birthday party tomorrow. ---______. A. I don't B. I won't C. I can't D. I haven't 答案B. will既可当作情态动词，表请求、建议、也可作为实义动词表"意愿、意志、决心"，本题表示决心，选B。 6.13 带to 的情态动词 带to 的情态动词有四个：ought to, have to, used to, be to, 如加上have got to ,(=must), be able to，为六个。它们的疑问，否定形式应予以注意： Do they have to pay their bill before the end of the month? She didn't use to play tennis before she was fourteen. You ought not to have told her all about it. Ought he to see a heart specialist at once.? ought to 本身作为情态动词使用。其他的词作为实义动词使用，变疑问，否定时，须有do 等助动词协助。 典型例题 Tom ought not to ___ me your secret, but he meant no harm. A.have told B.tell C.be telling D. having told 答案A。由于后句为过去时，告诉秘密的动作又发生在其前因，此地应用过去完成时，但它在情态动词 ought to 后，所以用have。
6.14 比较need和dare 这两词既可做实义动词用，又可做情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句。 need 作实义动词时后面的不定式必须带to，而dare作实义动词用时, 后面的to 时常可以被省略。 1) 实义动词： need （需要, 要求） need + n. / to do sth 2) 情态动词： need，只用原形need后加do，否定形式为need not。 Need you go yet? Yes, I must. / No, I needn't. 3) need 的被动含义：need, want, require, worth（形容词）后面接doing也可以表示被动： need doing = need to be done
第七讲 非限定动词非限定动词P142/非谓语动词?
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式，动名词，和分词(分词包括现在分词和过去分词)。 1）不定式 时态语态 主动 被动 一般式 to do to be done 完成式 to have done to have been done 2）动名词 时态语态 主动 被动 一般式 doing being done 完成式 having done having been done 3）分词 时态语态 主动 被动 一般式 doing being done 完成式 having done having been done 否定形式： not +不定式， not + 动名词， not + 现在分词
7.1分词 （现在分词和过去分词）?
1. 分词作定语 分词前置 We can see the rising sun. 我们可以看到东升的旭日 He is a retired worker. 他是位退休的工人 分词后置 (i分词词组；ii 个别分词如given, left； iii 修饰不定代词 something等) There was a girl sitting there. 有个女孩坐在那里 This is the question given. 这是所给的问题 There is nothing interesting. 没有有趣的东西 过去分词作定语 与其修饰的词是被动关系，相当于一个被动语态的定语从句。 Most of the people invited to the party were famous scientists. Most of the artists invited to the party were from South Africa.
典型例题 1) The first textbook ___ for teaching English as a foreign language came out in the 16th century. A. have written B. to be written C. being written D. written 答案D. 书与写作是被动关系，应用过去分词做定语表被动，相当于定语从句 which is written 2）What's the language ____ in Germany? A. speaking B. spoken C. be spoken D. to speak 答案B. 主语language与谓语动词之间有被动的含义。 spoken是动词speak的过去分词形式，在句中作定语，修饰主语language, spoken 与 language有被动关系。该句可以理解为： What's the language (which is) spoken in German
2 分词作状语 As I didn't receive any letter from him, I gave him a call. -> Not receiving any letter from him, I gave him a call. 由于没有收到他的信，我给他打了电话。 If more attention was given, the trees could have grown better. -> Given more attention，the trees could have grown better. 假如多给些照顾，那些树会长得更好。 典型例题 1）_____ some officials, Napoleon inspected his army. A. Followed B. Followed by C. Being followed D. Having been followed 答案B. Napoleon 与follow 之间有被动的含义。being followed除表达被动之外，还有动作正在进行之意。 followed by（被…跟随）。本题可改为： With some officials following, Napoleon inspected his army. 2）There was a terrible noise ___ the sudden burst of light. A. followed B. following C. to be followed D. being followed 答案B. 由于声音在闪电后，因此为声跟随着光，声音为跟随的发出者，为主动。用现在分词。
3）_______, liquids can be changed into gases. A. Heating B. To be heated C. Heated D. Heat 答案C. 本题要选一分词作为状语。现在分词表主动，正在进行的；过去分词表被动的，已经完成的。对于液体来说是加热的受动者，是被动的，因而选C。它相当于一个状语从句 When it is heated，… 注意： 选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。 (Being ) used for a long time, the book looks old. 由于用了很长时间，这本书看上去很旧。 Using the book, I find it useful. 在使用的过程中， 我发现这本书很有用。
3 连词+分词(短语)?
有时为使分词短语与主句关系更清楚，可在分词前加连词。 连词有： when，while，if though，after, before, as. 但分词的主语和主句的主语必须为同一个，如： While waiting there, he saw two pretty girls come out of the building. waiting 和saw 的主语相同。
4 分词作补语?
通常在感官动词和使役动词之后，如： I found my car missing. 我发现我的车不见了。 I‘ll have my watch repaired. 我想把我的手表修一下。
5分词作表语?
现在分词： 表示主动，正在进行 过去分词： 表示被动，已经完成 She looked tired with cooking. 她由于忙着做饭，看上去有些疲倦。 He remained standing beside the table. 他依然站在桌旁。
6 分词作插入语?
其结构是固定的，意思上的主语并不是句子的主语。 generally speaking 一般说来 talking of (speaking of) 说道 strictly speaking 严格的说 judging from 从…判断 all things considered 从整体来看 taking all things into consideration 全面看来 Judging from his face, he must be ill. 从他的脸色看，他一定是病了。 Generally speaking, dogs can run faster than pigs. 总的来说，狗比猪跑得快。 (speaking 并不是dogs 的动作)
7 分词的时态?
1）与主语动词同时， Hearing the news, he jumped with joy. 听到这一消息，他高兴得手舞足蹈。 Arriving there, they found the boy dead. 刚一到那儿，他们就发现那男孩死了。 典型例题 The secretary worked late into the night, ___a long speech for the president. A. to prepare B. preparing C. prepared D. was preparing 答案B. 此处没有连词，不能选D，否则出现了两个谓语动词worked和was preparing。 只能在B，C中选一个。又因前后两个动作同时发生，且与主语为主动关系，应用现在分词。
2）先于主动词 While walking in the garden，he hurt his leg. 在花园里散步时他伤了腿。 分词作时间状语，如果先与主动词的动作，且强调先后， 要用having done。 Having finished his homework, he went out. =As he had finished his homework, he went out. 做完作业后，他出去了。 典型例题 ___ a reply, he decided to write again. A. Not receiving B. Receiving not C. Not having received D. Having not received 答案C. 本题考查分词的时态与分词的否定式。根据题意判断，分词的动作（接信）发生在谓语动词的动作（决心再写信）之前，因此用分词的完成式。分词的否定式的构成为not +分词，故选C。该句可理解为：Because he had not received a reply, he decided to write again.
8 分词的语态?
1）通常，现在分词表示主动，过去分词表示被动，例如： He is the man giving you the money. (= who gave you…) 他就是给你钱的那个人。 He is the man stopped by the car. ( = who was stopped by…) 他就是那个被车拦住的人。 2）不及物动词的过去分词表示动作已经发生 gone, fallen, retired, grown-up, escaped, faded, returned 例: a well-read person. 一个读过许多书的人 a much-travelled may 一个去过许多地方的人 a burnt-out match 烧完了的火柴
7.2 动名词 1 动名词作主语、宾语和表语 1）作主语 Fighting broke out between the South and the North. 南方与北方开战了。 2）作宾语 a. 动词后加动名词doing作宾语 V. + doing sth admit 承认 appreciate 感激,赞赏 avoid 避免 complete 完成 consider 认为 delay 耽误 deny 否认 detest 讨厌 endure 忍受 enjoy 喜欢 escape 逃脱 prevent阻止 fancy 想象 finish 完成 imagine 想象 mind 介意 miss 想念 postpone 推迟 practise 训练 recall 回忆 resent 讨厌 resist 抵抗 resume 继续 risk 冒险 suggest 建议 face 面对 include 包括 stand 忍受 understand 理解 forgive 宽恕 keep 继续

2 worth 的用法?
worth，worthy，worth-while都为adj. 意为"值得"。 1. worth： be worth + n. 当名词为金钱时，表示"…… 值得……" be worth doing sth.

1） 单数名词词尾加 ’s，复数名词词尾没有s，也要加‘s，如the boy’s bag 男孩的书包，men‘s room 男厕所。
专有名词s结尾（一般应加’s）Charles’s job 2） 若名词已有复数词尾-s ，只加’s，如：the workers' struggle 工人的斗争。 3） 凡不能加"'s"的名词，都可以用"名词+of +名词"的结构来表示所有关系，如：the title of the song 歌的名字。 4） 在表示店铺或教堂的名字或某人的家时，名词所有格的后面常常不出现它所修饰的名词，如：the barber's 理发店。 5） 如果两个名词并列，并且分别有's，则表示"分别有"；只有一个's，则表示'共有'。 如：John's and Mary's room（两间） John and Mary's room（一间） 6） 复合名词或短语，'s 加在最后一个词的词尾。 如：a month or two's absence 双重所有格（of+’s的两种结合）P11-13 (textbook)

词修饰的名词时不定冠词放形容词后： Brave a man though he is，he trembles at the
sight of snakes.

double，half，twice，three times等词之后，名词之前。 All the students in the class went out.
班里的所有学生都出去了。 2.6数词(P69-77)
表示数目多少或顺序多少的词叫数词，数词分为基数词和序数词。表示数目多少的数词叫基数词；表示顺序的数词叫序数词。
一、基数词 1）基数词写法和读法： 345 three hundred and forty-five； 2）基数词一般是单数形式，但下列情况，常用复数： a. 与of 短语连用，表示概数，不能与具体数目连 用，如scores of people 指许多人； b. 在一些表示"一排"或"一组"的词组里； 如：They arrived in twos and threes. 他们三三两两的到达了。 c. 表示"几十岁"； d. 表示"年代"，用 in +the +数词复数； e. 在乘法运算的一种表示法里，如：3 x 5 = 15
Three fives is (are) fifteen. 数词总结：
1。基数词和序数词的形式。（复合数字307586610）
大概数目（hundreds of people, millions of birds ）dozen, score 用法相同。 （ 十二个鸡蛋；六打；八十；好几十个人；成打的鸡蛋）

代词是代替名词的一种词类。大多数代词具有名词和形容词的功能。英语中的代词，按其意义、特征及在句中的作用分为：人称代词、物主代词、指示代词、自身代词、相互代词、疑问代词、关系代词和不定代词八种。 一、人称代词是表示“我”、“你”、“他”、“她”、“它”、 我们"、"你们"、"他们"的词。人称代词有人称、数和格的变下表： 数 单数 复数 格 主格 宾格 主格 宾格 第一人称 I me we us 第二人称 you you you you he him they them 第三人称 she her they them it it they them 如：He is my friend. 他是我的朋友。 It's me. 是我。
二、 物主代词表示所有关系的代词，也可叫做代词所有格。
物主代词分形容性物主代词和名词性物主代词二种，其人物和数
的变化见下表。 数 单数 复数 人称 第一 第二 第三 第一 第二 第三 人称 人称 人称 人称 人称 人称 形容词性 my your his/her its our your/their 物主代词 名词性 mine yours his/hers its ours yours/theirs 物主代词
如： I like his car. 我喜欢他的小汽车。
Our school is here，and theirs is there. 我们的学校在这儿，他们的在那儿。 三、 指示代词表示“那个”、“这个”、“这些”、“那些”等指示概念的代词。
指示代词有this，that，these，those等。 如： That is a good idea. 那是个好主意。
四、 表示“我自己”、“你自己”、“他自己”、“我们自己”、“你们自己
”和“他们自己”等的代词，叫做自身代词，也称为“反身代词”。 如： She was talking to herself. 她自言自语。
五、 表示相互关系的代词叫相互代词，有each other 和one another两组，但在运用中，这两组词没什么区别。 如： They love each other. 他们彼此相爱。 六、 不是指明代替任何特定名词的代词叫做不定代词。常见的不定代词有a11，both，each，every等，以及含有some-，any-，no-等的合成代词，如anybody， something，no one。这些不定代词大都可以代替名词和形容词，在句中作主语、宾语、表语和定语， 但none和由some，any，no等构成的复合不定代词只能作主语、宾语或表语；every和no只能作定语。如： --- Do you have a car? --你有一辆小汽车吗？ --- Yes，I have one. --是的，我有一辆。 --- I don't know any of them. 他们，我一个也不认识。 七、 疑问代词有who，whom，whose，what和which等。在句子中用来构成特殊疑问句。疑问代词都可用作连接代词，引导名词性从句（主语从句、宾语从句和表语从句） 如：Tell me who he is. 告诉我他是谁。 八、 关系代词有who，whom，whose，that，which，as等，可用作引导从句的关联词。它们在定语从句中可作主语、表语、宾语、定语等；另一方面它们又代表主句中为定语从句所修饰的那个名词或代词（通称为先行词）。 如： He is the man whom you have been looking for. 他就是你要找的那个人。 3.2人称代词的用法(P28-31)Let’s与 let us 有时有异义．Let’s多用来表劝告或建议，包括自己与对方在内．
Let’s go, shall we?
Let’s start at once.
在不包括对方的情况下，须用Let us
Please let us know the time of your arrival.
Please let us buy you a drink.3.3并列人称代词的排列顺序 1) 单数人称代词并列作主语时，其顺序为： 第二人称 －> 第三人称 －> 第一人称 you －> he/she; it -> I You, he and I should return on time. 2) 复数人称代词作主语时，其顺序为： 第一人称 －> 第二人称 －> 第三人称 we －> you －> They 注意： 在下列情况中，第一人称放在前面。 a. 在承认错误，承担责任时， It was I and John that made her angry. 是我和约翰惹她生气了。 b. 在长辈对晚辈，长官对下属说话时，如长官为第一人称， 如：I and you try to finish it. c. 并列主语只有第一人称和第三人称时， d. 当其他人称代词或名词被定语从句修饰时。 3.4物主代词 (P32-34)形容词性
名词性3.5双重所有格物主代词不可与 a, an, this, that, these, those, some, any, several, no, each, every, such, another, which等词一起前置，修饰一个名词，而必须用双重所有格。 公式为： a, an, this, that +名词+of +名词性物主代词。如： a friend of mine. each brother of his. 3.6反身代词1） 列表 I you you she he myself yourself yourselves herself himself we they it one ourselves themselves itself oneself 2）做宾语 a. 有些动词需有反身代词 absent, bathe, amuse, blame, dry, cut, enjoy, hurt, introduce, behave We enjoyed ourselves very much last night. 我们昨晚玩得很开心。 Please help yourself to some fish. 请你随便吃点鱼。 b. 用于及物动词+宾语+介词 take pride in, be annoyed with, help oneself to sth. I could not dress (myself) up at that time. 那个时候我不能打扮我自己。 注：有些动词后不跟反身代词， get up, sit-down, stand up, wake up等。 Please sit down. 请坐。
3） 作表语； 同位语 be oneself: I am not myself today. 我今天不舒服。 The thing itself is not important. 事情本身并不重要。 4） 在不强调的情况下，but, except, for 等介词后宾语用反身代词或人称代词宾格均可。如： No one but myself (me) is hurt. 注意： a. 反身代词本身不能单独作主语。 (错) Myself drove the car. (对) I myself drove the car. 我自己开车。 b. 但在and, or, nor连接的并列主语中，第二个主语可用反身代词，特别是myself 作主语。 Charles and myself saw it. 5）第二人称作宾语，要用反身代词。 You should be proud of yourself. 你应为自己感到骄傲。 习惯用法(P35-37)textbook
among themselves
between ourselves
by oneself
for oneself
in oneself
(not) be oneself
to oneself3.7相互代词one another & each other
(p37-38)3.8指示代词和疑问代词１．指示代词(such; so; same)的用法
P40-48
２．疑问代词 P48-513.9关系代词 1） 关系代词用来引导定语从句。它代表先行词，同时在从句中作一定的句子成分，例如：The girl to whom I spoke is my cousin. 跟我讲话的姑娘是我表妹。（该句中whom既代表先行词the girl，又在从句中作介词to的宾语。） 2） 关系代词有主格，宾格和属格之分，并有指人与指物之分。在限定性定语从句中，that 可指人也可指物，见表： 限定性 非限定性 限定性 指 人 指 物 指人或指物 主 格 who which that 宾 格 whom that that 属 格 whose of which/whose of which/whose 例如： This is the pencil whose point is broken. 这就是那个折了尖的铅笔。 (whose 指物，在限定性定语从句中作定语) He came back for the book which he had forgotten. 他回来取他丢下的书。 （which指物，在限定性定语从句中作宾语，可以省略） 3） 关系代词which的先行词可以是一个句子，例如： He said he saw me there, which was a lie. 他说在那儿看到了我，纯属谎言。 说明： 关系代词that在从句中作宾语或表语时可省略， 例如： I've forgotten much of the Latin I once knew. 我过去懂拉丁语，现在大都忘了。 He's changed. He's not the man he was. 他变化很大，已不是过去的他了。 3.10不定代词every , no, all, both, neither, nor? 1）不定代词有 all , both, every, each, either, neither, more, little, few, much, many, another, other, some, any , one, no 以及some, something, anything, everything, somebody, someone, anybody, anyone, nothing , nobody, no one, none, everybody, everyone.等。 2） 不定代词的功能与用法 a. 除every 和no外不定代词既可用作名词，也可用作形容词。every和no在句中只能作定语。 I have no idea about it. b. all 都，指三者以上。 all 的主谓一致：all的单复数由它所修饰或指代的名词的单复数决定。 All goes well. 一切进展得很好。 all 通常不与可数名词单数连用，如：不说 all the book，而说 the whole book。 但all可与表时间的可数名词单数连用，如 all day，all night，all the year； 但习惯上不说 all hour，all century。 all还可以与一些特殊的单数名词连用，如 all China， all the city， all my life， all the way 3) both 都，指两者。 a. both 与复数动词连用，但 both… and…可与单数名词连用。 b. both, all 都可作同位语，其位置在行为动词前， be 动词之后。如果助动词或情态动词后面的实义动词省 去，则位于助动词或情态动词之前。 Who can speak Japanese? We both (all) can. . 4) neither 两者都不 a. neither作主语时，谓语动词用单数。 b. 作定语与单数名词连用，但neither… nor 用作并列连词，可与复数名词连用。其谓语采用就近原则。 c. 可用于下列句型，避免重复。 She can't sing，neither (can) he.
neither 与nor d. 如前句是否定式从句，则主句用neither，而不用 nor。 If you don't do it，neither should I. 如果你不干，我也不干。 e. 如后连续有几个否定句式，则用nor，不用neither。 He can't sing，nor dance，nor skate. none, few, some, any, one, ones? 一、 none 无 1) none作主语，多与of 构成短语 none of。 在答语中，none可单独使用。 Are there any pictures on the wall? None. 2) none作主语，谓语动词单复数均可。但如做表语，则其单复数与表语一致。 It is none of your business. 二、few 一些，少数 few 作主语时，谓语动词用复数，多用于肯定句。 三、some 一些 1) 可与复数名词及不可数名词连用。 2) 当做"某一"解时，也可与单数名词连用。（= a certain） You will be sorry for this some day. 总有一天，你会后悔这件事的。 A certain (some) person has seen you break the rule. 某些人不同意你的看法。 注意： (1)在肯定疑问句中用some代替any。 (2)some用于其他句式中: a. 肯定疑问句中：说话人认为对方的答案会是肯定的，或期望得到肯定回答时。 Would you like句式中，表委婉请求或建议，如： Would you like some coffee? b. 在条件状语从句中表示确定的意义时，如： If you need some help，let me know. c. some位于主语部分, Some students haven't been there before d. 当否定的是整体中的部分时，some可用于否定句。如： I haven't heard from some of my old friends these years. 这些年我没有收到一些老朋友的信。 四、any 一些 1) any 多用于否定句和疑问句和条件状语从句中。 当句中含有任何的意思时，any可用于肯定句。 Here are three novels. You may read any. 这有三本小说，你可任读一本。 五、one, ones 为复数形式 ones必须和形容词连用。如果替代的名词时无形容词在前，则用some, any，而不 用ones。 Have you bought any rulers? Yes，I 've bought some. ? 代词比较辩异 one，that 和it?
one表示泛指，that和it 表示特指。that与所指名词为同类，但不是同一个，而it 与所指名词为同一个。 I can't find my hat. I think I must buy one. (不定) 我找不到我的帽子了。我想我该去买一顶。 The hat you bought is bigger than that I bought. (同类但不同个) 你买的那顶帽子比我买的大。 I can't find my hat. I don' t know where I put it. ( 同一物) 我找不到我的帽子。我不知道我把它放在哪了。 one/another/the other
? one… the other 只有两个 some… the others 有三个以上 one… another，another… some… others，others… others = other people/things the others = the rest 剩余的全部 1) 泛指另一个用another。 2) 一定范围内两人(物)，一个用one，另一个用the other。 3) 一定范围内三者，一个用one，另一个用one (another)，第三个可用the other，a third。 4) 一定范围内，除去一部分人/物，剩余的全部用the others。 5) 泛指别的人或物时，用others当在一定范围内，除去一部分后，剩余部分但不是全部时，也用others。 both, either, neither, all, any, none?
这些词都可用作代词或形容词。其位置都在be 动词之后，行为动词之前或第一助动词之后。 1) both (两者都)，either(两者中任何一个)， neither (两者都不)。以上词使用范围为两个人或物。 Neither of the two boys is clever. 两个男孩都不聪明。 2) both，either both与复数连用，either与单数连用。 Both the boys are clever. 两个男孩都很聪明。 Either of the two boys is clever. 两个男孩都很聪明。 There are flowers on both sides of the street. (两岸) There are flowers on either side of the street. (岸的两边) 路边长满了野花。 3) all (所有的，全部的人或物)，any (任何一个)， none (都不)。 以上词使用范围为三者以上。 All the flowers are gone. 所有的花都谢了。 I don't like any of the flowers. 这些花我都不喜欢。 I like none of the flowers. 这些花我都不喜欢。 注意：all与none用法一样。跟单数名词，用单数动词；跟复数名词，用复数动词。 All of the students are there. 所有的学生都在那。 All (of) the milk is there. 所有的牛奶都在那。 few, little, a few, a little (a) few + 可数名词, (a) little + 不可数名词 a few / a little 为肯定含义，还有一点 few / little 为否定含义，没有多少了。 He has a few friends. 他有几个朋友。 He has few friends. 他几乎没有朋友。 We still have a little time. 我们还有点时间。 There is little time left.几乎没剩下什么时间了。 典型例题: Although he 's wealthy，he spends___ on clothes. A. little B. few C. a little D. a few 答案： A. spend所指的是钱，不可数，只能用little或 a little. 本句为although引导的让步状语从句，由句意知后句为否定含义，因此应用little表示几乎不。 固定搭配: only a few (=few) not a few (=many) quite a few (=many) many a (=many) Many books were sold. Many a book was sold. 卖出了许多书。 第四讲 动词的时态概念（时间与时态）
时态是一种语言的手段，因语言的不同而有区别。英语时态以动词形式变化表示句中谈到的动作、状态的时间关系和说话的时间。（十一种）P79表格
1 一般现在时的用法?
1) 经常性或习惯性的动作，常与表示频腮度的时间状语连用。 时间状语： every…, sometimes, at…, on Sunday I leave home for school at 7 every morning. 2) 客观真理，客观存在，科学事实。 The earth moves around the sun. Shanghai lies in the east of China. 3) 表示格言或警句中。 Pride goes before a fall. 骄者必败。 注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。 例：Columbus proved that the earth is round.. 4) 现在时刻的状态、能力、性格、个性。 I don't want so much. Ann Wang writes good English but does not speak well. 比较：Now I put the sugar in the cup. I am doing my homework now. 第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。
现在进行时?4.2.1现在进行时的基本用法： a. 表示现在( 指说话人说话时) 正在发生的事情。 We are waiting for you. b. 习惯进行：表示长期的或重复性的动作，说话时动作未必正在进行。 Mr. Green is writing another novel. (说话时并未在写，只处于写作的状态。) She is learning piano under Mr. Smith. c. 表示渐变的动词有：get, grow, become, turn, run, go, begin等。 The leaves are turning red. It's getting warmer and warmer. d. 与always, constantly, forever 等词连用，表示反复发生的动作或持续存在的状态，往往带有说话人的主观色彩。 You are always changing your mind. 典型例题 My dictionary ___, I have looked for it everywhere but still___ it. A. has lost, don‘t find B. is missing, don’t find C. has lost, haven‘t found D. is missing, haven’t found. 答案D. 前句是一个仍在持续的状态，应用进行时，由于没有找到，其影响仍然存在，应用完成时，瞬间动词用于否定式时可用于完成时。
2.不用进行时的动词?
1) 事实状态的动词 have, belong, possess, cost, owe, exist, include, contain, matter, weigh, measure, continue I have two brothers. This house belongs to my sister. 2) 心理状态的动词 Know, realize, think see, believe, suppose, imagine, agree, recognize, remember, want, need, forget, prefer, mean, understand, love, hate I need your help. He loves her very much. 3 ) 瞬间动词 accept, receive, complete, finish, give, allow, decide, refuse. I accept your advice. 4) 系动词 seem, remain, lie, see, hear, smell, feel, taste, get, become, turn You seem a little tired.
4.3一般过去时1）在确定的过去时间里所发生的动作或存在的状态。 时间状语有：yesterday, last week, an hour ago, the other day, in 1982等。 Where did you go just now? 2）表示在过去一段时间内，经常性或习惯性的动作。 When I was a child, I often played football in the street. Whenever the Browns went during their visit, they were given a warm welcome. 3）句型： It is time for sb. to do sth "到……时间了" "该……了" It is time sb. did sth. "时间已迟了" "早该……了" It is time for you to go to bed. 你该睡觉了。 It is time you went to bed. 你早该睡觉了。 would (had) rather sb. did sth. 表示'宁愿某人做某事' I'd rather you came tomorrow. 4) wish, wonder, think, hope 等用过去时，作试探性的询问、请求、建议等。 I thought you might have some. 我以为你想要一些。 比较： 一般过去时表示的动作或状态都已成为过去，现已不复存在。 Christine was an invalid all her life. (含义：她已不在人间。) Christine has been an invalid all her life. (含义：她现在还活着) Mrs. Darby lived in Kentucky for seven years. (含义：达比太太已不再住在肯塔基州。) Mrs. Darby has lived in Kentucky for seven years. ( 含义：现在还住在肯塔基州，有可能指刚离去) 注意： 用过去时表示现在，表示委婉语气。 1）动词want, hope, wonder, think, intend 等。 Did you want anything else? I wondered if you could help me. 2）情态动词 could, would. Could you lend me your bike?
4.4过去进行时（P108 略）4.5现在完成时
1现在完成时用来表示之前已发生或完成的动作或状 态，其结果的确和现在有联系。动作或状态发生在过去 但它的影响现在还存在；也可表示持续到现在的动作或 状态。其构成： have (has) +过去分词。
(2)用于现在完成时的句型 ?
1）It is the first / second time…. that…结构中的从句部分，用现在完成时。 It is the first time that I have visited the city. It was the third time that the boy had been late. 2）This is the… that…结构，that 从句要用现在完成时. This is the best film that I've (ever) seen. 这是我看过的最好的电影。 This is the first time (that) I've heard him sing. 这是我第一次听他唱歌。
典型例题 (1) ---Do you know our town at all? ---No, this is the first time I ___ here. A. was B. have been C. came D. am coming 答案B. This is the first time 后面所加从句应为现在完成时，故选B。
2) ---Have you ____ been to our town before? ---No, it's the first time I ___ here. A. even, come B. even, have come C. ever, come D. ever, have come 答案D. ever意为曾经或无论何时，反意词为never，此两词常用于完成时。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中，从句要用完成时。 注意：非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。 （错）I have received his letter for a month. （对）I haven't received his letter for almost a month.
3比较过去时与现在完成时?
1）过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。 2）过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。 一般过去时的时间状语: yesterday, last week，…ago, in1980, in October, just now, 具体的时间状语 共同的时间状语: this morning, tonight,this April, now, once，before, already, recently，lately 现在完成时的时间状语 for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always, 不确定的时间状语
3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know. 过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。 举例： I saw this film yesterday. （强调看的动作发生过了。） I have seen this film. （强调对现在的影响，电影的内容已经知道了。） Why did you get up so early? （强调起床的动作已发生过了。） Who hasn‘t handed in his paper? （强调有卷子，可能为不公平竞争。） She has returned from Paris. 她已从巴黎回来了。 She returned yesterday. 她是昨天回来了。 He has been in the League for three years. (在团内的状态可延续) He has been a League member for three years. (是团员的状态可持续)
He joined the League three years ago. ( 三年前入团，joined为短暂行为。) I have finished my homework now. ---Will somebody go and get Dr. White? ---He's already been sent for. 句子中如有过去时的时间副词（如 yesterday, last, week, in 1960）时，不能使用现在完成时，要用过去时。 （错）Tom has written a letter to his parents last night. （对）Tom wrote a letter to his parents last night.
4比较since和for?
Since 用来说明动作起始时间，for用来说明动作延续时间长度。 I have lived here for more than twenty years. I have lived here since I was born.. My aunt has worked in a clinic since 1949. Some new oilfields have been opened up since 1976. I have known Xiao Li since she was a little girl. My brother has been in the Youth League for two years. I have not heard from my uncle for a long time. 注意：并非有for 作为时间状语的句子都用现在完成时。 I worked here for more than twenty years. (我现在已不在这里工作。) I have worked here for many years. (现在我仍在这里工作。)
小窍门： 当现在完成时+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。 1) (对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now. 2) (错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now. 显然，第二句不对，它应改为 Harry got married six years ago. 或 Harry has been married for six years. 5.延续动词与瞬间动词?
1) 用于完成时的区别 延续动词表示经验、经历； 瞬间动词表示行为的结 果，不能与表示段的时间状语连用。 He has completed the work. 他已完成了那项工作。 (表结果) I‘ve known him since then. 我从那时起就认识他了。(表经历) 2) 用于till / until从句的差异 延续动词用于肯定句，表示“做……直到……” 瞬间动词用于否定句，表示“到……，才……” He didn’t come back until ten o‘clock. 他到10 点才回来。 He slept until ten o’clock. 他一直睡到10点。
4.5 将来一般时1.用法
1) shall用于第一人称，常被will 所代替。 will 在陈述句中用于各人称，在争求意见时常用于第二人称。 Which paragraph shall I read first. Will you be at home at seven this evening? 2) be going to +不定式，表示将来。 a. 主语的意图，即将做某事。 What are you going to do tomorrow? b. 计划，安排要发生的事。 The play is going to be produced next month。 c. 有迹象要发生的事 Look at the dark clouds, there is going to be a storm. 3) be +不定式表将来，按计划或正式安排将发生的事。 We are to discuss the report next Saturday. 4) be about to +不定式，意为马上做某事。 He is about to leave for Beijing. 注意：be about to 不能与tomorrow, next week 等表示明确将来时的时间状语连用。
2.be going to / will?
用于条件句时， be going to 表将来 will 表意愿 If you are going to make a journey, you'd better get ready for it as soon as possible. Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.
3.be to和be going to ?
be to 表示客观安排或受人指示而做某事。 be going to 表示主观的打算或计划。 I am to play football tomorrow afternoon. (客观安排) I‘m going to play football tomorrow afternoon. (主观安排)
4.6过去完成时过去完成时?
1） 概念：表示过去的过去 ----|-------|-----|---->其构成是had +过去分词构成。 那时以前 那时 现在 2） 用法 a. 在told, said, knew, heard, thought等动词后的宾语从句。 She said (that) she had never been to Paris. b. 状语从句 在过去不同时间发生的两个动作中，发生在先，用过去完成时；发生在后，用一般过去时。 When the police arrived, the thieves had run away. c. 表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本…，未能…" We had hoped that you would come, but you didn't.
3) 过去完成时的时间状语before, by, until , when, after, once, as soon as。 He said that he had learned some English before. By the time he was twelve, Edison had began to make a living by himself. Tom was disappointed that most of the guests had left when he arrived at the party. 典型例题 The students ___ busily when Miss Brown went to get a book she ___ in the office. A. had written, left B，were writing, has left C. had written, had left D. were writing, had left 答案D. "把书忘在办公室"发生在"去取书"这一过去的动作之前，因此"忘了书"这一动作发生在过去的过去，用过去完成时。句中when表示的是时间的一点，表示在"同学们正忙于……"这一背景下，when所引导的动作发生。因此 前一句应用过去进行时。 注意： had no … when 还没等…… 就…… had no sooner… than 刚…… 就…… He had no sooner bought the car than he sold it.
4.7时态一致?
1) 如果从句所叙述的为真理或不变的事实，则永远用现在时。 At that time, people did not know that the earth moves. He told me last week that he is eighteen. 2) 宾语从句中的助动词ought, need, must, dare 时态是不变的。 He thought that I need not tell you the truth.
4.8 时态与时间状语?
时间状语 一般现在时 every …, sometimes, at …, on Sunday, 一般过去时 yesterday, last week, an hour ago, the other day, in 1982, just now 一般将来时 next…, tomorrow, in+时间, 现在完成时 for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always, recently
过去完成时 before, by, until, when, after, once, as soon as 过去进行时 this morning, the whole morning, all day, yesterday, from nine to ten last evening… when, while 将来进行时 soon, tomorrow, this evening, on Sunday, by this time, tomorrow, in two days, tomorrow evening
第五讲 动词语态动词的语态?
语态有两种：主动语态和被动语态。 主语是动作的发出者为主动语态；The cat caught the mouse.
主语是动作的接受者为被动语态。The mouse was caught by the mouse
被动语态构成形式：用于常用的七种时态。（p114-116)
1）若宾语补足语是不带to 的不定式，变为被动语态时，该不定式前要加"to"。此类动词为感官动词。 feel, hear, help, listen to, look at, make, observe, see, notice, watch The teacher made me go out of the classroom. --> I was made to go out of the classroom (by the teacher). We saw him play football on the playground. --> He was seen to play football on the playground. 2）情态动词+ be +过去分词，构成被动语态。 Coal can be used to produce electricity for agriculture and industry.
3.表示"据说"或"相信" 的词组?
believe, consider, declare, expect, feel , report, say, see, suppose, think, understand It is said that… 据说 It is reported that… 据报道 It is believed that… 大家相信 It is hoped that… 大家希望 It is well known that… 众所周知 It is thought that… 大家认为 It is suggested that… 据建议 It is taken granted that… 被视为当然 It has been decided that… 大家决定 It must be remember that…务必记住的是 It is said that she will leave for Wuhan on Tuesday.

2. 计划，安排
The train was supposed to arrive at 11:30, but it was 40 minutes late.

Did any of these houses get damaged in the storm last night?
第六讲 情态动词6.1 情态动词的语法特征 1） 情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。 2） 情态动词 除ought 和have 外，后面只能接不带to 的不定式。 3） 情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。 4） 情态动词没有非谓语形式，即没有不定式，分词，等形式
6.2 比较can 和be able to?
1）can could 表示能力；可能 (过去时用could), 只用于现在式和过去式(could)。be able to可以用于各种时态。 They will be able to tell you the news soon. 他很快就能告诉你消息了。 2）只用be able to a. 位于助动词后。 b. 情态动词后。 c. 表示过去某时刻动作时。 d. 用于句首表示条件。 e. 表示成功地做了某事时，只能用was/were able to， 不能用could
He was able to flee Europe before the war broke out. = He managed to flee Europe before the war broke out. 注意：could不表示时态 1）提出委婉的请求，（注意在回答中不可用could）。 --- Could I have the television on? --- Yes, you can. / No, you can't. 2）在否定，疑问句中表示推测或怀疑。 He couldn't be a bad man. 他不大可能是坏人。
P124
be able to 表示在特定情景中努力做成某事。
The first spread through the building very quickly, but luckily everyone was able to escape.
大火在楼里蔓延，幸好大家都及时撤离了。（在此不能用could ）
They didn’t want to come with us at first, but in the end we were able to persuade them.
起初他们不想与我们一起来，但是最后我们还是说服了他们。（在此不能用could）
6.3 比较may和might ） 表示允许或请求；表示没有把握的推测；may 放在句首，表示祝愿。 May God bless you! He might be at home. 注意： might 表示推测时，不表示时态。只是可能性比may 小。 2） 成语： may/might as well，后面接不带to 的不定式，意为"不妨"。 If that is the case, we may as well try. 典型例题 Peter ___come with us tonight, but he isn't very sure yet. A. must B. may C. can D. will 答案B. 表可能性只能用may. 此句意可从后半句推出。
6.4 比较have to和must 1) 两词都是'必须'的意思，have to 表示客观的需要， must 表示说话人主观上的看法，既主观上的必要。 My brother was very ill, so I had to call the doctor in the middle of the night. 我弟弟病得很厉害，我只得半夜里把医生请来。(客观上需要做这件事) He said that they must work hard. 他说他们必须努力工作。（主观上要做这件事） 2) have to有人称、数、时态的变化，而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。 He had to look after his sister yesterday.
3） 在否定结构中： don‘t have to 表示“不必” mustn’t 表示“禁止”，
You don‘t have to tell him about it. 你不一定要把此事告诉他。 You mustn’t tell him about it. 你一定不要把这件事告诉他。
6.5 must表示推测 1) must用在肯定句中表示较有把握的推测，意为"一定"。 2) must表对现在的状态或现在正发生的事情的推测时， must 后面通常接系动词be 的原形或行为动词的进行式。 You have worked hard all day.You must be tired. 你辛苦干一整天，一定累了。（对现在情况的推测判断） He must be working in his office. 他一定在办公室工作呢。 比较： He must be staying there. 他现在肯定呆在那里。 He must stay there. 他必须呆在那。
3) must 表示对已发生的事情的推测时，must 要接完成式。 I didn't hear the phone. I must have been asleep. 我刚才没有听到电话，我想必是睡着了。 4) must表示对过去某时正发生的事情的推测，must 后面要接不定式的完成进行式。 ---Why didn't you answer my phone call? ---Well, I must have been sleeping, so I didn't hear it. 5) 否定推测用can't。 If Tom didn't leave here until five o'clock, he can't be home yet. 如果汤姆五点才离开这儿，他此时一定还未到家。 6.6 表示推测的用法 can, could, may, might, must 皆可表示推测，其用法如下： 1）情态动词+动词原形。 表示对现在或将来的情况的推测，此时动词通常为系动词。 I don't know where she is, she may be in Wuhan. 2）情态动词+动词现在进行时。 表示对现在或将来正在进行的情况进行推测。 At this moment, our teacher must be correcting our exam papers. 这时，我们老师想必在批改试卷。 3）情态动词+动词完成时。 表示对过去情况的推测。 We would have finished this work by the end of next December. 明年十二月底前我们很可能已完成这项工作了。 The road is wet. It must have rained last night. 地是湿的，昨天晚上一定下雨了。
4）情态动词+动词的现在完成进行时。 表示对过去正在发生事情的推测。 Your mother must have been looking for you. 你妈妈一定一直在找你。 5）推测的否定形式，疑问形式用can't, couldn't表示。 Mike can't have found his car, for he came to work by bus this morning. 迈克一定还没有找回他的车，因为早上他是坐公共汽车来上班的。 注意：could, might表示推测时不表示时态，其推测的程度不如can, may。
6.7 情态动词+ have +过去分词 1) may(might) have + done sth, can (could) have + done sth 表示过去，推测过去时间里可能发生的事情。 Philip may (might) have been hurt seriously in the car accident. Philip can (could) have been hurt seriously in the car accident. 2) must have +done sth，对过去时间里可能发生的事情的推测，语气较强，具有"肯定"，"谅必"的意思。 ---Linda has gone to work, but her bicycle is still here. ---She must have gone by bus. 3) ought to have done sth, should have done sth 本应该做某事，而事实上并没有做。否定句表示"不该做某事而做了"。
You ought to (should) have been more careful in this experiment. He ought not to have thrown the old clothes away.（事实上已扔了。） ought to 在语气上比should 要强。 4) needn't have done sth 本没必要做某事 I dressed very warmly for the trip, but I needn't have done so. The weather was hot. 5) would like to have done sth 本打算做某事 I would like to have read the article, but I was very busy .
6.8 should 和ought to should 和ought to 都为"应该"的意思，可用于各种人称。 ---Ought he to go? ---Yes. I think he ought to. 表示要求，命令时，语气由 should（应该）、had better最好）、must（必须）渐强。
6.9 had better表示"最好" had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。 had better do sth had better not do sth It is pretty cold. You'd better put on my coat. She'd better not play with the dog. had better have done sth表示与事实相反的结果，意为"本来最好"。 You had better have come earlier
.
6.10 would rather表示"宁愿" would rather do would rather not do would rather… than… 宁愿……而不愿。 还有would sooner, had rather, had sooner都表示"宁愿"、"宁可"的意思。 If I have a choice, I had sooner not continue my studies at this school. I would rather stay here than go home. = I would stay here rather than go home. 典型例题 ----Shall we go skating or stay at home? ----Which ___ do? A. do you rather B. would you rather C. will you rather D. should you rather 答案B。本题考查情态动词rather的用法，would rather +do sth 意为"宁愿"，本题为疑问句，would 提前，所以选B
6.11 will和would 注意： 1）would like； Would like to do = want to 想要，为固定搭配。 Would you like to go with me? 2）Will you…? Would you like…? 表示肯定含义的请求劝说时，疑问句中一般用some, 而不是any。 Would you like some cake? 3）否定结构中用will，一般不用would, won't you是一种委婉语气。 Won't you sit down?
6.12 情态动词的回答方式 问句 肯定回答 否定回答 Need you…? Yes, I must. No,I needn't Must you…? /don't have to. 典型例题 1）---Could I borrow your dictionary? ---Yes, of course, you____. A. might B. will C. can D. should 答案C.could表示委婉的语气，并不为时态。答语中of course，表示肯定的语气，允许某人做某事时，用can和 may来表达，不能用could或might。复习： will 与you连用，用来提出要求或下命令。should与you 连用，用来提出劝告。
2）---Shall I tell John about it? ---No, you ___. I've told him already. A. needn't B. wouldn't C. mustn't D. shouldn't
答案A。needn't 不必，不用。 wouldn't 将不, 不会的。 mustn't 禁止、不能。 shouldn't 不应该。本题为不需要，不必的意思，应用needn't。 3）---Don't forget to come to my birthday party tomorrow. ---______. A. I don't B. I won't C. I can't D. I haven't 答案B. will既可当作情态动词，表请求、建议、也可作为实义动词表"意愿、意志、决心"，本题表示决心，选B。 6.13 带to 的情态动词 带to 的情态动词有四个：ought to, have to, used to, be to, 如加上have got to ,(=must), be able to，为六个。它们的疑问，否定形式应予以注意： Do they have to pay their bill before the end of the month? She didn't use to play tennis before she was fourteen. You ought not to have told her all about it. Ought he to see a heart specialist at once.? ought to 本身作为情态动词使用。其他的词作为实义动词使用，变疑问，否定时，须有do 等助动词协助。 典型例题 Tom ought not to ___ me your secret, but he meant no harm. A.have told B.tell C.be telling D. having told 答案A。由于后句为过去时，告诉秘密的动作又发生在其前因，此地应用过去完成时，但它在情态动词 ought to 后，所以用have。
6.14 比较need和dare 这两词既可做实义动词用，又可做情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句。 need 作实义动词时后面的不定式必须带to，而dare作实义动词用时, 后面的to 时常可以被省略。 1) 实义动词： need （需要, 要求） need + n. / to do sth 2) 情态动词： need，只用原形need后加do，否定形式为need not。 Need you go yet? Yes, I must. / No, I needn't. 3) need 的被动含义：need, want, require, worth（形容词）后面接doing也可以表示被动： need doing = need to be done
第七讲 非限定动词非限定动词P142/非谓语动词?
在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。非谓语动词分为三种形式:不定式，动名词，和分词(分词包括现在分词和过去分词)。 1）不定式 时态语态 主动 被动 一般式 to do to be done 完成式 to have done to have been done 2）动名词 时态语态 主动 被动 一般式 doing being done 完成式 having done having been done 3）分词 时态语态 主动 被动 一般式 doing being done 完成式 having done having been done 否定形式： not +不定式， not + 动名词， not + 现在分词
7.1分词 （现在分词和过去分词）?
1. 分词作定语 分词前置 We can see the rising sun. 我们可以看到东升的旭日 He is a retired worker. 他是位退休的工人 分词后置 (i分词词组；ii 个别分词如given, left； iii 修饰不定代词 something等) There was a girl sitting there. 有个女孩坐在那里 This is the question given. 这是所给的问题 There is nothing interesting. 没有有趣的东西 过去分词作定语 与其修饰的词是被动关系，相当于一个被动语态的定语从句。 Most of the people invited to the party were famous scientists. Most of the artists invited to the party were from South Africa.
典型例题 1) The first textbook ___ for teaching English as a foreign language came out in the 16th century. A. have written B. to be written C. being written D. written 答案D. 书与写作是被动关系，应用过去分词做定语表被动，相当于定语从句 which is written 2）What's the language ____ in Germany? A. speaking B. spoken C. be spoken D. to speak 答案B. 主语language与谓语动词之间有被动的含义。 spoken是动词speak的过去分词形式，在句中作定语，修饰主语language, spoken 与 language有被动关系。该句可以理解为： What's the language (which is) spoken in German
2 分词作状语 As I didn't receive any letter from him, I gave him a call. -> Not receiving any letter from him, I gave him a call. 由于没有收到他的信，我给他打了电话。 If more attention was given, the trees could have grown better. -> Given more attention，the trees could have grown better. 假如多给些照顾，那些树会长得更好。 典型例题 1）_____ some officials, Napoleon inspected his army. A. Followed B. Followed by C. Being followed D. Having been followed 答案B. Napoleon 与follow 之间有被动的含义。being followed除表达被动之外，还有动作正在进行之意。 followed by（被…跟随）。本题可改为： With some officials following, Napoleon inspected his army. 2）There was a terrible noise ___ the sudden burst of light. A. followed B. following C. to be followed D. being followed 答案B. 由于声音在闪电后，因此为声跟随着光，声音为跟随的发出者，为主动。用现在分词。
3）_______, liquids can be changed into gases. A. Heating B. To be heated C. Heated D. Heat 答案C. 本题要选一分词作为状语。现在分词表主动，正在进行的；过去分词表被动的，已经完成的。对于液体来说是加热的受动者，是被动的，因而选C。它相当于一个状语从句 When it is heated，… 注意： 选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。 (Being ) used for a long time, the book looks old. 由于用了很长时间，这本书看上去很旧。 Using the book, I find it useful. 在使用的过程中， 我发现这本书很有用。
3 连词+分词(短语)?
有时为使分词短语与主句关系更清楚，可在分词前加连词。 连词有： when，while，if though，after, before, as. 但分词的主语和主句的主语必须为同一个，如： While waiting there, he saw two pretty girls come out of the building. waiting 和saw 的主语相同。
4 分词作补语?
通常在感官动词和使役动词之后，如： I found my car missing. 我发现我的车不见了。 I‘ll have my watch repaired. 我想把我的手表修一下。
5分词作表语?
现在分词： 表示主动，正在进行 过去分词： 表示被动，已经完成 She looked tired with cooking. 她由于忙着做饭，看上去有些疲倦。 He remained standing beside the table. 他依然站在桌旁。
6 分词作插入语?
其结构是固定的，意思上的主语并不是句子的主语。 generally speaking 一般说来 talking of (speaking of) 说道 strictly speaking 严格的说 judging from 从…判断 all things considered 从整体来看 taking all things into consideration 全面看来 Judging from his face, he must be ill. 从他的脸色看，他一定是病了。 Generally speaking, dogs can run faster than pigs. 总的来说，狗比猪跑得快。 (speaking 并不是dogs 的动作)
7 分词的时态?
1）与主语动词同时， Hearing the news, he jumped with joy. 听到这一消息，他高兴得手舞足蹈。 Arriving there, they found the boy dead. 刚一到那儿，他们就发现那男孩死了。 典型例题 The secretary worked late into the night, ___a long speech for the president. A. to prepare B. preparing C. prepared D. was preparing 答案B. 此处没有连词，不能选D，否则出现了两个谓语动词worked和was preparing。 只能在B，C中选一个。又因前后两个动作同时发生，且与主语为主动关系，应用现在分词。
2）先于主动词 While walking in the garden，he hurt his leg. 在花园里散步时他伤了腿。 分词作时间状语，如果先与主动词的动作，且强调先后， 要用having done。 Having finished his homework, he went out. =As he had finished his homework, he went out. 做完作业后，他出去了。 典型例题 ___ a reply, he decided to write again. A. Not receiving B. Receiving not C. Not having received D. Having not received 答案C. 本题考查分词的时态与分词的否定式。根据题意判断，分词的动作（接信）发生在谓语动词的动作（决心再写信）之前，因此用分词的完成式。分词的否定式的构成为not +分词，故选C。该句可理解为：Because he had not received a reply, he decided to write again.
8 分词的语态?
1）通常，现在分词表示主动，过去分词表示被动，例如： He is the man giving you the money. (= who gave you…) 他就是给你钱的那个人。 He is the man stopped by the car. ( = who was stopped by…) 他就是那个被车拦住的人。 2）不及物动词的过去分词表示动作已经发生 gone, fallen, retired, grown-up, escaped, faded, returned 例: a well-read person. 一个读过许多书的人 a much-travelled may 一个去过许多地方的人 a burnt-out match 烧完了的火柴
7.2 动名词 1 动名词作主语、宾语和表语 1）作主语 Fighting broke out between the South and the North. 南方与北方开战了。 2）作宾语 a. 动词后加动名词doing作宾语 V. + doing sth admit 承认 appreciate 感激,赞赏 avoid 避免 complete 完成 consider 认为 delay 耽误 deny 否认 detest 讨厌 endure 忍受 enjoy 喜欢 escape 逃脱 prevent阻止 fancy 想象 finish 完成 imagine 想象 mind 介意 miss 想念 postpone 推迟 practise 训练 recall 回忆 resent 讨厌 resist 抵抗 resume 继续 risk 冒险 suggest 建议 face 面对 include 包括 stand 忍受 understand 理解 forgive 宽恕 keep 继续
举例： (1) Would you mind turning down your radio a little, please? (2) The squirrel was lucky that it just missed being caught. b. 词组后接doing admit to prefer…to be used to lead to devote oneself to object to stick to busy look forward to(to为介词） no good, no use, It's worth…, as well as, can't help, It's no use /good be tired of be fond of be capable of be afraid of be proud of think of / about hold off put off keep on insist on count on / upon set about be successful in good at take up give up burst out prevent … from… 3）作表语 Her job is washing，cleaning and taking care of the children.
2 worth 的用法?
worth，worthy，worth-while都为adj. 意为"值得"。 1. worth： be worth + n. 当名词为金钱时，表示"…… 值得……" be worth doing sth. "……某事值得被做" The question is not worth discussing again and again. 2. worthy：be worthy of +n. 当名词为抽象名词时表示"……值得……" be worthy to be done "某事值得被做" The question is not worthy to be discussed againand again. 3. worth-while： be worth-while to do sth "值得做某事" worth while： It is worth while doing sth It is worth while sb to do sth. 典型例题 It is not ____ to discuss the question again and again. A.worth B.worthy C.worth-while D.worth while 答案C. 由worth的用法可知，此句只适合词组be worth-while to do sth.。因此选C。
7.3 动词不定式1 不定式作宾语 1) 动词+ 不定式 afford aim appear agree arrange ask be decide bother care choose come dare demand desire determine expect elect endeavor hope fail happen help hesitate learn long mean manage offer ought plan prepare pretend promise refuse seem tend wait wish undertake 举例： The driver failed to see the other car in time. 司机没能及时看见另一辆车。 I happen to know the answer to your question. 我碰巧知道你那道问题的答案。 2）动词+不定式 ； 动词+宾语+不定式 ask, beg, choose, expect , hate, help intend like, love, need prefer, prepare, promise, want, wish… I like to keep everything tidy. 我喜欢每件东西都保持整洁。 I like you to keep everything tidy. 我喜欢你年使每件东西都保持整洁。

I found him lying on the ground. I found it important to learn. I found that to learn English is important. 典型例题: The next morning she found the man ___ in bed，dead. A. lying B. lie C. lay D. laying 答案：A.find的宾语后面，用分词或分词短语，起宾语补足语作用。现在分词表达主动，也表达正在进行，过去分词表达被动。 2) to + be 的不定式结构，作补语的动词。 Acknowledge, believe, consider, think, declare(声称), discover, fancy(设想), feel find, guess, judge, imagine, know, prove, see(理解), show, suppose, take(以为), understand We consider Tom to be one of the best students in our class. 我们认为汤姆是班上最好的学生之一。 典型例题 Charles Babbage is generally considered ___ the first computer.
