二、精典名题导解
选择填空
1.The warmth of ____________sweater will of course be determined by the sort of ___________wool used.
A.The ; the B.the ; / C./; the D./; /
解析:答案为B。第一空格为特指,交待the warmth的内容,第二空格为泛指,the sort of wool used所用羊毛的种类。此题有三点需注意:①正确理解sweater 这一句词在句中的类别。②掌握determine在句中作“决定”、“取决于”这个意思。③掌握定冠词表特指的基本用法。
2.Most animals have little connection with_______animals of_________different kind unless they kill them for food.
A.the … a B./ … a C.the … the D./ … the
解析:答案为B。名词复数表类别,其前不用冠词,故第一个空格不填冠词,表不定概念的“一种”,“某种”要用不定冠词a。要准确掌握冠词表类别的三种表达方式和不定冠词常用的几种情况,见前面要点考点聚焦内容。
3.Paper money was in___________use in China when Marco Polo visited the country in __________thirteenth century.
A.the … / B.the … the C./ … the D./ … /
解析:答案为C。题中in use是固定搭配,意为“在使用”,use为抽象名词,其前不用冠词。后者是序数词前用定冠词the。要牢记一些固定搭配如in use、under construction(在建设中)、in debt(欠债)、come to power(执政)、on fire(着火)、at table(用餐)、out of work(失业)等。

Unit2 名词
一、考点聚焦
1.可数名词单、复数变化形式
(1)规则变化。
①单数名词词尾直接加-s。如:boy — boys, pen — pens。
②以s、x 、ch 、sh结尾的单词一般加-es。如:glass — glasses,box— boxes, watch — watches, brush — brushes。
特例:stomach — stomaches。
③以“辅音字母 + y”结尾的变“y”为“i”再加“-es”。如:
baby — babies, lady — ladies, fly — flies。
④以“o”结尾的多数加-es。如:tomato — tomatoes, potato — potatoes, hero — heroes。但以两个元音字母结尾的名词和部分外来词中以o结尾的词只加-s。 如:radio — radios, zoo — zoos, photo — photos, piano — pianos, kilo — kilos, tobacco — tobaccos。
⑤以“f”或“fe”结尾的名词复数形式变“f”或“fe”为“v”,之后再加-es。如:wife — wives, life — lives, knife — knives, wolf— wolves, self — selves, leaf — leaves等。特例:handkerchief— handkerchiefs, roof — roofs, chief — chiefs, gulf — gulfs, belief — beliefs, cliff — cliffs。

stores。(B)man和woman作定语修饰另一个名词时,前后两个名词都要变成复数。如:man doctor — men doctors, woman driver — women dri-
vers。(C)与介词或副词一起构成的复合名词应在主体名词部分加-s。如:brother-in-law — brothers-in-law, passer-by — passers-by。

deers 、deer。penny的两种复数形式含义有所不同。如:pence(便士的钱数),pennies(便士的枚数)。
(2)不规则变化。

2、不可数名词的数
(1)一般说来抽象名词为不可数名词,但当抽象名词表示具体的东西时,可用作可数名词且词义发生变化,主要类型如下:
①抽象名词表示具有某种特性、状态、感情情绪的人或事。如:
抽象名词(不可数) 具体化(个体名词,可数名词)

失败是成功之母。
by experience靠经验 an experience一次经历
youth青春 a youth一个青年人
have pity on sb.怜悯某人 a pity可惜的事情
with pleasure乐意 a pleasure乐事
②抽象名词与a(an)连用,淡化了抽象概念,转化为似乎可以体验到的动作、行为或类别。如:

Would you like to have a walk(swim, bath, talk)with me
It is waste of time reading such a novel.
She made an apology to her mother for her wrong doings.
(2)物质名词是不可数名词,但表示数量或种类之多时,可以用作可数名词。如:

have a wonderful breakfast They have a heavy snow every year.
Time and tide wait for no man.
We had a wonderful time last night.
(3)有复数形式的不可数名词
①有些抽象名词往往以复数形式出现,起到一种丰富语言感彩或强调某种特殊状态的作用。如:
Use your brains, please.
They have smoothed away the difficulties.
Have you made preparations for tomorrow’s meeting
Many thanks for your kindness.
No pains, no gains.
After many failures, they finally succeeded.
②有些物质名词以复数形式出现,表示数量之多,范围之广。如:
The boy burst into tears at the bad news.
The rising waters did a lot of harm to the crops.
The stone bridge broke down in heavy rains.
3.名词所有格
(1)“’s”所有格的特殊表示形式有:
用于表示时间、距离、价格、重量等的名词后,如:today’s
newspaper,five minutes’walk(drive),five pounds’weight, tend
ollars’worth of coffee。
②用于表示国家、世界、城市等地方的名词后。如:the earth’s planet, the word’s population, China’s industry, New York’s parks。
(2)“of”所有格的特殊表示方式有:
①表示“部分”时,一般在所修饰的名词前有一个表示数量的词(a、two、several、some、no、many等),如:Some students of Mister Zhang’s have gone to college.张老师的一些学生已经上大学了。
②表示“其中之一,其中一部分”的意思时,用:a friend of Tom’s
汤姆的一个朋友(许多朋友中的一位)。
③表示赞扬、批评或厌恶等感彩时,应该用:that/this/these/
those + 名词(单、复数)of Mary’s/yours/his/hers。如:
That invention of hers belongs to the world. 她的那项发明是属于全世界的(表赞赏)。
4、名词作定语
英语中有些名词没有其对应的同根形容词,这些名词可以直接用来作定语修饰另一个名词。
(1)分类意义。
air pollution 空气污染 boy friend 男朋友
coffee cup咖啡杯 income tax所得税
tennis ball网球 song writer歌曲作家
body language身体语言 road accident交通事故
Nobel Prize诺贝尔奖
(2)时间、地点、称呼等。
Doctor Jack杰克医生 Professor Li李教授
evening school夜校 winter sleep冬眠

village people村民 school education学校教育
China problem中国问题
(3)表目的、手段、来源,所属意义。
reception desk接待台 sports field田径场
stone table石桌 color TV彩电
weather report天气预报
二、精典名题导解
选择填空
1. It is generally believed that teaching is ___________it is a science.
A.an art much as B.much an art as
C.as an art much as D.as much an art as
解析:答案为D。当名词前有what、so、as、too、quite等词修饰时,其形容词被这些词修饰,组成下列结构,如:What a nice book! This is too heavy a box for me to carry. He is not as honest a boy as Mike.等,应采取too/how + 形容词(副词)+ a(an) + 名词的形式。要记住一些类似的特殊结构,并加以分析。
2. The police are offering a __________to anyone who can give information about the lost key.
A.price B.prize C.reward D.money
解析:答案为C。price 价格,价钱;prize奖金。D项是钱,属不可数名词,题中所要填的是“酬金,报酬”。注意正确理解名词的含义及其搭配是活用语言的基础,在复习备考中要熟练掌握考纲中一些名词的词义、搭配、习惯等,才能更好辨析名词,从而选择最符合句意的选项。
3.You’ll find this map of great _____________in helping you to get round London.
A.price B.cost C.value D.usefulness
解析:答案为C。本题考查特定语境中名词的词义及“be of + 抽象名词”结构。Price (价格),cost(价钱,费用,成本)不符合题意,value作“quality of being useful or desirable”解时,常与of搭配,在句中作表语或补语,意为“有用,有价值”。故选择value。注意名词词义辨异及惯用法表达,题中“of + 抽象名词”相当于该名词的形容词形式。

Unit2 代词
一、考点聚焦
代词分为九类:人称代词、物主代词、反身代词、相互代词、指示代词\疑问代词、连接代词、不定代词、关系代词。大多数代词具有名词和形容词的作用。
1、人称代词
(1)人称代词作主语用主格,作宾语、表语用宾格,但应注意以下4中情况:
①作主语的人称代词如果孤立地使用于无谓语动词的句子中,或在这种句子中与动词不定式连用,常用宾格。
—Does any of you know where Tom lives
—Me.
What! Me (to)play him at chess No!
②句子中代词作宾语或宾语补足语时,与所替代的名词在人称、数、格在意义上一般要保持前后一致。
The thief was thought to be he.(the thief是主格,故用he代替)
They took me to be her.他们误以为我是她。(me是宾格,故用her
替代)
③作表语人称代词一般用宾格,但在强调句型中,被强调部分代词的格不变。
I met her in the hospital.→It was her who I met in the hospital.
④在比较级的句子中than、as后用主格、宾格都可以。如:He is taller than me(I).但在下列句中有区别。
I like Jack as much as her.=I like both Jack and her.
I like Jack as much as she.=I like Jack and she likes him, too.
(2)两个以上的人称代词并列,其次序排列原则:
①在并列主语中,“I”总是放在最后,排列顺序为:二 三 一(人称)。宾格me也一样。
You ,she and I will be in charge of the case.
Mr.Zhang asked Li Hua and me to help him.
②第三人称,男女两性并用,男先女后。
He and she still don’t agree to the plan.
(3)几个人称代词的特殊用法。
①we/you(口语)常用来泛指一般人。
②she可以代表国家、船只、大地、月亮等。
The “Titanic”was the largest, wasn’t she
2.物主代词
(1)名词和形容词性物主代词各自的语法功能。
(2)one’s own…=...of one’s own句式的转换。
(3)某些固定结构中常用定冠词代替物主代词。
如: take sb. by the arm, be wounded in the leg.
3.反身代词
(1)反身代词的语法功能:宾语、表语、主语或宾语的同位语。
(2)反身代词和某些动词连有,构成固定短语。
enjoy oneself, feel oneself, make oneself at home, make oneself understood
(3)反身代词还可用于某些成语中。
for oneself为自己或独立地,of oneself自然地,自动地
by oneself独自地,in oneself本身性质,beside oneself喜怒哀愁至极
This problem gets a chapter to itself.这个问题占了一章(独有)。
Just between ourselves, I don’t think much of him.私下地说我并不怎么看重他。
They were discussing about it among themselves.(相互共同)
Left to himself he began to write.别人走后只留下他,他写了起来。
I’m very angry with myself.生自己的气。
4.相互代词(each other, one another)
相互代词无人称、数和格的区别,在句中作宾语。其所有格分别为each other’s 、one another’s ,作定语。
一般来说,each other指两者之间,one another指三者或三者以上之间,但现在区分已不明显。
5.指示代词(this, that , these, those, such, same)
指示代词具有形容词和代词两种词性,在句子中可以作定语、主语、宾语或表语等。
(1)指示代词this和that的区别。
①this (these)一般指时间或空间上较近的人或物;that(those)常指时间或空间较远的人或物。
This is my desk and that is yours.
In those days they could not go to school.
②this常指后面要讲到的事物,有启下的作用;that则指前面讲到过的事物,有承上的作用。
I want to tell you this:the English party will be held on Saturday
afternoon.
He hurt his leg yesterday. That’s why he didn’t come.
③为了避免重复,常用that或those代替前面已提过的名词。
The weather of Beijing is colder than that of Nanjing.
The ears of a rabbit are longer than those of a fox.
④this在电话用语中作自我介绍,that询问对方;this和that可以当副词用,意思相当于副词so。
(2)such和same的用法。
①such指“这样的”人或事,在句中作主语和定语。
Such was the story.
We have never seen such a tall building.
②same指“同样的”人或事,在句中作主语、表语、宾语和定语,same的前面要用定冠词the.
The same can be said of the other article.
另一篇文章也是同样的情况。(主语)
Whether he can do it or not,it is all the same to me.
他是否能做这事,对我来说都一样。(表语)
6、疑问代词(who,whom,which,what,whose)
疑问代词在句中作主语、宾语、定语和表语。
(1)who/what
①询问姓名或关系。——Who is he ——He is my brother./He is
Henry.询问职业或地位。——What is he? ——He is a lawyer/teacher.
②What/who 作主语时,谓语动词的数取决于说话人的视点,可单数也可复数。
What is /are on the table
Who is/are in the library
(2)which与who、what
which表示在一定范围内,而who、what则无此限制。
I found two books on the desk.Which is yours
7.连接代词和关系代词
连接代词与疑问代词的形式相同,主要有who、whom、whose、what、which以及它们与ever合成的代词whoever、whomever、whatever、whichever等。它们用来引导主语从句,宾语从句和表语从句,即连接复合句中的主句和从句,并在从句中担任一定的句子成分,以连接代词引起的名词性从句前不能再加that.
关系代词是用来引导定语从句的代词,它们包括who、whom、whose、which、that等。这两类代词的用法详见“名词性从句”和“定语从句”部分。
8、不定代词
不定代词主要有:all、each、every、both、either、neither、one、none、little、few、many、much、other、another、some、any、no等。还有由some、any、no和every构成合成代词,不定代词具有名词和形容词的性质,并有可数和不可数之分,在句中可以作主语、表语、宾语、同位语、定语、状语等(every、no只能作定语)。下面介绍几组主要不定代词的用法与区别。

④some 用于否定句表示部分否定。

(5)no和none
no=not any,表示“没有”,用来修饰可数名词或不可数名词,通常作定语,none代替不可数名词作主语时,谓语动词用单数形式;代替可数名词作主语时,谓语动词可用单数也可用复数形式。none还可以在句中作宾语。
注意:none既可以指人又可以指物,no one只能指人。
(6)each和every
each(各个),指两个或两个以上的人或物,侧重个体,在句中作主语、宾语、定语和同位语。every(每个),指三个或三个以上的人或物,侧重整体,在句中只能作定语。
Every student it our class has a dictionary.(定语,强调班上“所有的人”)
Each student in our class has a dictionary.(定语,强调各个个体)
Each of them has been there.(主语)
The teacher gave each of the students a new textbook.(宾语)
We each got a ticket.(同位语)
(7)either和neither
either是“两者中任何一个”的意思,可修饰或代替单数可数名词,neither是“两者中没有一个”的意思,可以修饰或代替单数可数名词,它们可在句在作主语、宾语或定语。如:
Here are two pens. You may take either of them.(宾语)
Neither boy knows French.(定语)
注意:①either也作副词,其意为“也”,用于否定句的句末。He doesn’like tea, and I don’t either.(状语)②either与or构成连词,意为“不是……就是……”或“要么……要么……”。He is either Japanese or Chinese. ③neither用作副词,意为“也不”,即“not…either”。He can’t do it, neither can I. ④neither可与nor构成连词,意为“既不……也不”。Neither he nor you are a student.
(8)other和another, the others 和others
the other表示“两者中的另一个”;“the other + 复数可数名词”
表示“其余(他)的……”;the others表示“其他的人或物”。“others及other + 复数名词”泛指“其他的(别的)人或物”。这些词语在句中可作主语、宾语和定语。如:
He got two books; one is textbook, the other is a novel.
Five of the pencils are red, the others(the other pens)are yellow.
Some are singing, others are dancing.
another修饰或代替单数可数名词,意为“(三个或三个以上的)另一个”,不能指两者中的另一个,在句中可作宾语和定语。
This coat is too dark. Please show me another.(宾语)
Please give me another book.(定语)
注意:another修饰复数名词时,意为“再,又”。如:Please give me another ten minutes. one … another(a second)… a third…the other…意为“一个……一个……一个……一个”用于三者或三者以上的排列。some…others…others…,意为“一些……一些……一些”。
二、精典名题导解
选择填空
1. The Parkers bought a new house but__________will need a lot of work before they can move in.
A.they B.it C.one D.which
解析:答案为B。分析题意可知,they显然不合,which多引导从句,从此为并列句式,one表示泛指,而此处空格内容指代前面提到的the new house。要仔细区别代词的所指范围,是人还是物,单数还是复数,另应注意句式。
2.If you want to change for a double room you’ll have to pay_________$ 15.
A.another B.other C.more D.each
解析:答案为A。本题考查不定代词用于表示数量附加的用法。“another + 数字 + 复数名词”结构通常用来表示在原有数量上的附加。若选C,正确结构是“数词 + more + 复数名词”。掌握another和more与数字搭配的位置是此题关键。another放在数字前,more放在数字后。NMET 1995中第25小题命题思路与此题一致。
3. Few pleasures can equal ___________of a cool drink on a hot day.
A.some B.any C.that D.those
解析:答案为C。本题考查替代词that的用法。that通常在句中替代同类的、特定的但不是同一的事物。本句中that替代the pleasure。句意为“在炎热的夏天几乎没有任何乐趣能与饮一杯冷饮的乐趣相比”。that指代单数或不可数名词,复数用those,表示特指,以避免重复,在比较句型中较为常用,代替可数名词时可换用the one。

Unit4 形容词和副词
一、考点聚焦
1、形容词、副词的作用与位置
形容词是用来修饰名词的,常被放在名词前作定语,或放在系动词后面作表语。而副词则用来修饰形容词、动词,其他副词或者句子,一般位于形容词之前,动词之后或句子之首。以下属几种特殊情况,须牢记;
(1)形容词短语作定语,定语后置。
a language difficult to master, a leaning tower about 180 feet high
(2)表语形容词(afraid、alike、alone、asleep、awake、alive等)作定语,定语后置。如a man alive。有些表身体健康状况的形容词如well、faint、ill只作表语。sick既可作表语又可作定语,ill如作定语意为“bad”。
(3)用作定语,修饰由不定代词one、no、any、some和every构成的复合词如anything、something等时,通常后置。如:
I have something important to tell you.
(4)else常用作疑问代词和不定代词的后置定语。
(5)enough、nearby修饰名词前置或后置,程度副词一般位于形容词、副词前面,enough修饰形容词、副词时,必须后置。
(6)几个副词并列作状语时,其顺序较灵活,但一般是:方式→地点→时间。如:
We had a good time together outdoors last Sunday.
(7)频度副词如often、always、usually等在be动词后,行为动词前。
(8)副词作定语,定语后置。如:
The person there is waiting for you.
(9)几个并列的形容词作定语,其语序通常为:限定语(The、A)+ 描绘性形容词 + size(大小)+ shape(形状)+ age(年龄、时间)+ color(颜色)+ origin(国籍、来源)+ material(材料)+ purpose(目的)+ 名词。如:
a heavy black Chinese steel umbrella,
the man’s first tow interesting little red French oil paitings
(10)以-ly结尾的词性辨析。
①下列单词以-ly结尾,但却是形容词而非副词:lively、lonely、lovely、deadly、friendly、ugly、silly、likely、brotherly、timely等。
②表愿意(无-ly)和引申意(有-ly)的副词:
deep深 wide宽广 high高 low位置低
deeply深入地 widely广泛地 highly高度地 lowly地位卑微
③有无-ly意义大不相同的副词:
dead完全,绝对be dead asleep
deadly非常be deadly tired
pretty相当be pretty certain that…
prettily漂亮地be prettily dressed
close近Don’t sit close.
closely密切地Watch closely!
late晚、迟arrive late, come late
lately最近I haven’t seen him lately(recently).
2、复合形容词的构成
(1)形容词 + 名词 + ed
kind-hearted好心的,white-haired白发的
(2)形容词 + 形容词
red-hot炽热的,dark-blue深蓝的
(3)形容词 + 现在分词
good-looking好看的,easy-going随和的
(4)副词 + 现在分词
hard-working勤劳的,fast-moving快速转动的

(9)数词 + 名词 + ed
four-storeyed 4层楼的,three-legged 3条腿的
(10)数词 + 名词(名词用单数)
ten-year 10年的,two-man两人的
3、形容词和副词的比较等级
(1)原级的构成和用法。
构成:形容词、副词的原级即本身。
用法:表示双方在程度、性质、特征等某方面相等时,用“as + 原级形容词/副词 + as”的结构;表示双方不相等时,用“not so(as) + 原级形容词/副词 + as”的结构;表示一方是另一方的若干倍时,用“倍数 + as + 原级形容词/副词 + as”的结构。如:
Xiao Wang is as tall as Xiao Yu.
This building looks not so (as)high as that one.
Miss Xu speaks English as fluently as you .
This room is three times as large as that one.
(2)比较级和最高级的构成。
掌握比较级和最高级的变化规则,熟记少数不符合规则的特殊形容词和副词。
(3)比较级的用法。
①对方比较,表示一方超过另一方时,用“比较级 + than”的结构表示。如:
This picture is more beautiful than that one.
②表示一方不及另一方时,用“less + 原级 + than”的结构表示。如:
This room is less beautiful than that one.
③表示一方超过另一方的程度或数量时,可在比较级前加表示程度的状语,如even、a lot、a bit、a little、still、much、far、yet、by fay等修饰。如:
He works even harder than before.
注意:英语的比较级前如无even、still或yet等时,译成汉语时可用“较”或“…一些”或不译出,一般不可有“更”。如:
She is better than she was yesterday
Please come earlier tomorrow.
另注意:by far通常用于强调最高级。用于比较级时,一般放在比较级的后面,如在前面,应在二者中间加“the”。如:
He is taller by far than his brother.
He is by far the taller of the two brothers.
④表示一方随另一方的程度而变化时,用“the + 比较级(主语 + 谓语),the + 比较级(主语 + 谓语)”的结构(意为“越……越……”)。如:
The harder he works, the happier he feels.
⑤不与其他事物相比,表示本身程度的改变时,用“比较级 + and + 比较级”的结构。如:
The weather is getting colder and colder.
The girl becomes more and more beautiful.
⑥某些以-ior结尾的形容词进行比较时,用to代替than。这些词有inferior(劣等的,次的)、superior(较好的,优于……)、junior(资历较浅的)、senior(资格较老的)、prior(在……之前)等。
He is superior to Mr.Zhang in chemistry.
⑦在比较从句中为了避免重复,我们通常用that(those)、one(ones)代替前面出现的名词。that指物,one既可指人又可指物。that可代替可数名词单数和不可数名词,而one只能代替可数名词。
The book on the table is more interesting than that(或the one)on the desk.
A box made of steel is stronger than one made of wood.
⑧倍数表达法。(A)A is three(four, etc.)times the size(height, length etc.)of B.这座新楼是那座旧楼的四倍大(高)。The new bui9lding is four times the size(the height)of the old one.这座新楼比那座旧楼大三倍(高三倍)。(B)A is three(four, etc.)times as big(high, long, etc.)as B. Asia is four times as large as Europe.亚洲比欧洲大三倍。(C)A is three (four, etc.)times bigger(higher, longer, etc.)than B. Your school is three times bigger than ours.你们的学校比我们的学校大三倍。用times 表倍数通常用于三倍以上,两倍可以用twice或double.
(4)最高级的用法。
①三者或三者以上相比,表示最高程度时,用“the + 最高级”的结构表示。这种句式一般常有表示比较范围的介词短语。如:
Zhang Hua is the tallest of the three.
He works(the)hardest in his class.
②最高级可被序数词以及much、by far、nearly、almost 、by no means、not quite、not really、nothing like等词语所修饰。如:
This hat is by far / much / nearly / almost / not nearly / by no means / not quite / nothing like the biggest.
How much did the secon most expensive hat cost
③表示“最高程度”的形容词,如excellent、extreme、perfect等,没有最高级,也不能用比较级。
④形容词最高级修饰作表语或介词宾语的名词、代词时,被修饰的词往往省略。如:
He is the tallest(boy)in his class.
⑤作状语的副词最高级前可以不加定冠词。如:
Of all the boys he came(the)earliest.
(5)形容词和副词前面使用冠词的情况。
①形容词最高级前一般要加定冠词,副词最高级前可不加冠词。
②形容词最高级前有时加不定冠词,或不加冠词,不表比较,表示“非常”。如:
He is a most clever young policeman.(a most=very)
The film is most interesting.(most=very)
③表示两者间“较……的一个”比较级前加the。如:
who is the older of the tow boys
④在“the + 比较级…,the + 比较级…”结构中。
⑤在same前一般要加the。
⑥有些形容词前加the 成为名词。如the poor、the rich 等。
(6)由as / so组成的形容词或副词短语。
as much as + 不可数名词数量。
Each stone weighs as much as fifteen tons.
She could earn as much as ten dollars a week.
②as many as + 可数名词数量 多达
I have as a many as sixteen referrence books.
③as early as早在
As early as the twelfth century the English began to invade the island.
④as far as远到;就……而知(论)
We might go as far as (走到)the church and back.
As far as I know(就我所知),he has been there before.
⑤may (might, could)as well不妨、不如
Then you might as well stay with us here.
⑥as … as can be到了最……的程度,极其
They are as unreliable as they can be.他们极其不可信。
⑦as … as one can
He began to run, as fast as he could.
⑧as … as possible
Just get them to finish up as quickly as possible.
(7)几组重要的词语辨析。
①very 和much的区别。(A)可分等级的形容词和副词前使用very不用much。(B)表示状态的过去分词前用very。a very frightened boy, a very tired child, a very complicated problem, 一般的情况下,以-ing、-ed结尾的分词多用much、very much / greatly等修饰。如:We were greatly shocked by the news about Tom. I was much amused by Jack’s attitude。(C)已转化为形容词的现在分词前用very。如:very interesting / worrying / exicting。(D)too前用much或far,不用very。You are much / far / a lot too nice.另外,在too many / much, too few / little前用far。 There’s far too little opportunity for adventue these days.We’ve got far too many eggs and far too few egg cups.(E)关于原级形容词要记住下列固定的修饰结构:(a)修饰绝对意义的形容词,一般不用very,而用quite completely、well、entirely。如:quite wrong(mistaken, sure)、completely dead、quite impossible、quite perfect等。(b)修饰以a-开头的形容词,多有特殊的修饰词:quite alone, very much alone, wide awake, fast asleep, very much afraid。(c)修饰一些特殊形容词的修饰语有:be well worth, much the same, freezing cold, quite different, terribly cold / frightening。
②so … that … 与such … that … 的区别。
so + 形容词 / 副词 + that …
so + 形容词 + a(n)+ 单数可数名词 + that …
so + many / much / little / few + 名词 + that …
such + a(n)+ 形容词+单数可数名词 + that …
such + 形容词 + 不可数名词 + that …
such + 形容词 + 复数名词 + that …
注意:下列结构中只能用so不可用such,当名词前有many、much、little、few等表示“多、少”的词修饰时,如 so much progress、so many people、so little food、so few apples等。但当little表示“小”时用such。如:These are such little boys that they can’t dress themselves.下列so的用法是错误的:so a diffcult problem,so difficult problems, so hot weather。
③其他几组词的辨析。(A)ago、before:ago表示以现在为起点的“以前”;before指以过去或将来的某时刻为起点的“以前”。泛指“以前”用before而不用ago。(B)already、yet、still:already表示某事已经发生;yet表示期待某事发生;still表示某事还在进行,主要用于肯定句。
(C)too、also、either:too和also用于肯定句,too多用于口语,also多用于书面语,either用于否定句。(D)good、well:与good不同的是,well作形容词,只能在系动词后作表语,表示“身体状况好”,也作副词修饰动词。(E)quick、fast:作形容词皆表“快”。fast多指运动的物体,含持续的意思。quick多指一次动作的敏捷、突然,而且持续的时间较短。(F)real、true:形容词表“真的”。real强调真实存在的而不是幻想的,在句中常作定语;true指与事实标准和实际情况相符合,在句中作表语或定语。(G)hard、difficult:均表“困难”,但hard通常指体力上困难;difficult则指智力或技能上的困难,困难程度大于hard。它们都可作定语和表语。
二、精典名题导解
选择填空
1. It is generally believed that teaching is ___________it is a science.
A.an art much as B.much an art as
C.as an art much as D.as much an art as
解析:答案为D。本题可从考查形容词的同级比较点入手。在同级比较as…as句式中,如果as后面的形容词作定语且其所修饰的名词前有不定冠词时,该冠词须置于形容词之后,即形成“as + 形容词 + a / an + 单数可数名词 + as”结构。这道题在名词专题中也有解析,不同的是观察视角不同,应注意培养发散思维。
2. It is always difficult being in a foreign country, __________if you don’t speak the language.
A.extremely B.naturally C.basically D.especially
解析:答案为D。本题考查副词的词义辨析。注意掌握词语的准确含义,结合语境进行分析。A项意为“极端地”;B项意为“自然地”;C项“基本上”;D项“尤其,特别地”。根据句意“如果你不会讲(它的)语言,在国外你就总会困难重重”可知答案。
3. Professor White has written some short stories, but he is ______known for his plays.
A.the best B.more C.better D.the most
解析:答案为C。本题考查副词的比较级和最高级。要把握句式之间的联系,抓住句子的隐藏信息,结合语境进行分析。根据句意,句中but后应有一词组be well known for…。同时,应注意到前后两个分句把professor White的短篇小说和戏剧进行了对比,故应用well的比较级。

Unit5 介词和连词
一、考点聚焦
1、介词的分类与语法功能
(1)介词是虚词,不能单独作句子成分,必须与名词、代词(或相当于名词的其他词类、短语或从句等)构成介词短语,在句中充当一个成分。介词分为:简单介词,如at、in、for等;合成介词,如within、inside、onto、througout等;短语介词,如according to、out of、because of、by means of、in spite of、instead of等。双重介词,如from behind / above / under、until after等。分词介词,如considering、including、judging(from / by) 等。

②in five days(weeks, months, years)中in意思是“在……以后”。
③in和during表一段时间内两词可互用。如:in the night, during the night, in the war, during the war。但略有区别:当接表示“活动”的抽象名词时多用during,接“活动”的动名词及短语时用in。如:

He didn’t get up till(until) 10 a.m.(不可用to).
但注意:在句首出现或强调句型中一般不用till而用until。如:
Not until 9 a.m.did Mr.Smith come back to school.
②to表“终结”时常用和from连用,但要注意不与from连用时的意
义。如:from July to September, from six to(till)eight(从……到……为止),但from morning till night(从早到晚),不能用to。from … to常构成习惯搭配,不可换用其他介词。(A)表持久连续、传递、转移的含义。from time to time(不时,有时),from day to day (天天),from hand to hand(不断传下去),from place to place(处处,到处),from side to side(左右摇摆),from door to door(家家户户),from house to house(挨家挨户),from shop to shop(一个商店接一个商店)。(B)表起始终止的全过程或程度加深、状态变化。from beginning to end(从头到尾,自始至终)(from the beginning to the end of…);from hand to mouth(仅能糊口),from bad to worse(越来越糟),from head to foot(从头到脚),

①It is clever of you to answer it like that.
②It is quite hard for me to explain why.

(15)几个常用的并列连词。

both … and“双方都”,连接句子的两个主语时,其后谓语动词通常用使用复数形式。either … or与neither … nor注意采取“就近原则”。
②not only … but also, as well as
注意:两者强调对象不同,not only … but also强调的是but also之后部分,而as well as则强调其前面的部分。not only … but also采取“就近原则”,而as well as只是一个插入语,采取“就远原则”。如:

When I go to the station, the train had already left.
He sang merrily as he was working.
②till、until均表示“到……时候止”,肯定句中的谓语必须是延续性动作。如:I worked till late at night.若主句谓语是终止性动词,则主句要用否定形式,意为动作“到……才……”开始发生。如:
She didn’t get up until her mother came in.
注意:till和until通常情况下可以互换,只是在句首时until比till更常用。
③though、although均引导让步状语从句,意为“虽然……”,although较正式,though最常用。如:
Thouth (Although)he was tired,he kept on working.
注意:though、although引导的从句不能与but、however连用,但可以与yet、still连用。though还可以与别的词结合使用,如even though、
as though,而although则不能这样搭配。
④no sooner … than、hardly … when、as soon as三者都表示“一……就”,“刚刚……就”的意思。(A)as soon as 置于主句前后都可以,而且有备各种时态。如:As soon as she gets here I’ll tell her about
it. Mary left as soon as the finished the work.(B)hardly … when、no sooner … than不能表示将来的事,其主句的谓语动词一般用过去完成时,从句用过去时。若将hardly或no sooner放在句首,句子要倒装。如:No sooner had he arrived than he went away again.
⑤某些表示时间的名词(词组)也可用作从属连词。它们是:the moment, the minute,the instant, the day, the time, the first(second, third …)time, the spring (summer, autumn,winter),every(each,next,
any) time(day),by the time,都可引导时间状语从句。如:
His mother died the spring he returned.
Call me up the minute he arrives.
二、精典名题导解
选择填空
1. The home improvements have taken what little there is _________my spare time.
A.from B.in C.of D.at
解析:答案为C。本题考查句子结构中介词of的有法。what引导的从句作谓语have taken的宾语,而从句中的基本句型为“there is little of …”,表示“……有很少”,what 修饰little提到了从句句首。注意正确把握句子结构和介词用法,要明白of my spare time和in my spare time的区别。
2. ____________ production up by 60%, the company has had another excellent year.
A.As B.For C.With D.Through
解析:答案为C。本题考查with的复合结构作状语的用法。“with + 名词 + 不定式/分词/名词/形容词/介词短语等”可在句中作伴随、时间、原因、条件等状语。本题中with的复合结构作伴随状语。
3. The changes in the city will cost quite a lot, ___________they will save us money in the long run.
A.or B.since C.for D.but
解析:答案为D。本题考查并列连词or、for、but和从属连词的意义和用法。并列连词or通常表示选择关系;for表示因果关系;but表示转折关系;从属连词since表示原因。通过比较前后两个分句意思可知,它们是转折关系。
4. After she considered the problem, she got a tall box to stand ________.
A.on B.up C.above D.by
解析:答案为A。不定式“to stand + 介词”作定语修饰a tall box,其中被修饰词在逻辑意义上是不及物动词,只有加上吊尾介词,句子意思才完整。吊尾介词往往由于受到汉语的影响而缺少,吊尾介词使用的场合有:
(1)定语从句中,先行词被一个不及物动词所修饰,不及物动词后要接介词,先行词被“动词 + 介词”组成的短语动词所修饰,介词常在句尾。
He is the man I just spoke to.
(2)what、whose、who、whatever等引导的宾语从句,宾语从句出现吊尾介词。
I can’t imagine what it is like.
(3) 强调句型,特殊疑问句中由于被强调部分和疑问词位置变更,常出现吊尾介词。
It was the poor boy that we gave the books to.
What for Where to Who with
(4)不及物动词的不定式修饰表“涉及对象、场合、工具、方式、材料”等意义的名词时常带吊尾介词。
a room to live in, a bench to sit on
There is nothing to worry about.
She is a good girl to work with.
(5)某些形容词后接不定式或“动词 + 介词”型短语,动词的不定式形式表“反射”,常用吊尾介词。
①fit、easy、hard、comfortable、difficult、heavy等形容词后。
②The river is good to swim in.
The box is too heavy to carry.
③be worth doing sth.,be worthy of being done / to be done, want/
require / need doing

Unit6 数 词
一、考点聚焦
1、序号表示法
(1)单纯的序号,可在基数词前加number,简写为No.。如:No.1第一号
(2)事物名词的序号表达法有什所不同:
①对于一些小序号可有序数词也可用基数词表达,形式分别为:the +
序数词 + 名词;名词 + 基数词。如:第一次世界大战可以表示为the First World War或World War One。
②对于一些大序号我们通常只用一种表达法,即名词 + 数词。如:501号房间表示为Room 501, 538路公共汽车表示为Bus 538。
③可用a / the + number + 基数词 + 名词。如:a No.5 bus一辆五路公共汽车,the No.8 bus那辆8路公共汽车。
2、倍数的表达方式
一般情况下我们用以下三种倍数表达方式:
(1)倍数用在as + 形容词 / 副词(原级)+ as结构之前。如:
They have three times as many cows as we do.
(2)倍数放在形容词或副词的比较级之前或by + 倍数用在比较级之后。如:
This rope is four times longer than that one.
They produced more products in 2001 than those in 2000 by twice.
(3)倍数用在表示度量名词前,其基本结构为:倍数 + the + size / length / weight … + of + 表示比较对象的名词,也可用于倍数 + what引导的从句中。如:
This room is three times the size of that one.
The college is twice what it was 5 years age.
You can’t imagine that rats eat 40 to 50 times their weight.
3、大约数的表示方法
(1)用ten、dozen、score、hundred、thousand、million等数词的复数后加of短语来表示几十、几百、上千、成千上万等大约数概念。如:
The little boy buys dozens of pencils every term.
Thousands of people died in the earthquake.
Every year tens of thousands of people go to work in Guangdong Province.
(2)用、less than、under、below、almost、nearly、up to 等来表示小于或接近某数目。如:
He is good at English, so he can finish the paper in less than two hours.
(3)用more than、over、above、beyond、or more等来表示超过或多于某个数目。如:
Peking University has a history of more than 100 years.
(4)用or、or so、about、around、some、more or less等表示在某一数目左右。如:
About 50 people were present at that time.
(5)用to、from … to…、between … and表示介于两数词。如:
His salary rises from 20 dollars a week to 35 dollars a week.
(6)注意事项:dozen、score、hundred、thousand、million作数词表示确切数量时,不用复数。如:three score, five dozen, seven million等。
4、分数的表达方式
(1)分子用基数词,分母用序数词,分子大于1时,分母用复数。如:one-third三分之一,three-sevenths七分之三。
(2)分子与分母之间加in, 分子在前,分母在后,分子分母都用基数词。如:one in ten 十分之一,five in eight八分之五。
(3)分子与分母之间加out of , 分子在前,分母在后,分子分母都用基数词。如:one out of ten十分之一,five out of eight八分之五。
5、百分数的表示法
(1)表示百分数直接将数词放在单词percent前面即可,如:twenty percent百分之二十。
(2)分数和百分数后面不能直接接名词或代词,而用以下形式:分数/百分数 +of + 冠词 / 限定词 + 名词 / 代词 ,其谓语动词与of后的名词在人称和数上保持一致,如:
Two-thirds of the money was spent on food.
About seventy percent of the earth surface is covered by water.
6、小数的表示法
小数的表示法,小数点前的总值发同其他数词一样,小数点用point,小数点后面的数读成个位数,如:9.65表示为nine point six five。218.39表示为two hundred and eighteen point three nine。
二、精典名题导解
选择填空
1. ____________ people in the world are sending information by E-mail every day.
A.Several million B.Many millions
C.Several millions D.Many million
解析:答案为A。本题考查的是million表示确切数量的用法。million前需用数表确切数量,而不用many这类词,但可说many millions of(上百万的),故本题中用Several million。
2. The number of people invited __________ fifty, but a number of them __________ absent for different reasons.
A.were ; was B.was ; was C.was ; were D.were ; were
解析:答案为C。本题考查的是the number of + 名词与a number of + 名词作主语时谓语的单复数问题。the number of是“……的数目”,作主语时谓语动词用单数,而a number of 后接可数名词的复数形式,作主语时谓语动词用复数形式,故此题最佳选项为C。
3. Shortly after the accident, two ___________ police were sent to the sport to keep order .
A.dozens of B.dozens C.dozen D.dozen of
解析:答案为C。此题考查的是数词dozen表示确切数量时的用法,dozen表示确切数量时用其单数形式,当dozens的复数后接of时则表示不确切数量,本题答案为C。
