第一章 名词性从句
　　在句子中起名词作用的句子叫名词性从句(Noun Clauses）。 名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
一． 主语从句
　　主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。
1. It 作形式主语和it引导强调句的比较
It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who/whom。例如：
a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。
b) It doesn’t interest me whether you succeed or not.　我对你成功与否不感兴趣。
c) It is in the morning that the murder took place.　谋杀案是在早上发生的。（强调句型）
d) It is John that broke the window.　是John打碎的窗户。（强调句型）
2. 用it 作形式主语的结构
(1) It is ＋ 名词 ＋ 从句
It is a fact that … 事实是…
It is an honor that …非常荣幸
It is common knowledge that …是常识
(2) It is ＋ 形容词 ＋ 从句
It is natural that… 很自然…
It is strange that… 奇怪的是…
(3) It is ＋ 不及物动词 ＋ 从句
It seems that… 似乎…
It happened that… 碰巧…
It appears that… 似乎…
(4) It ＋ 过去分词 ＋ 从句
It is reported that… 据报道…
It has been proved that… 已证实…
It is said that… 据说…
3. 主语从句不可位于句首的五种情况：
（1）if 引导的主语从句不可居于复合句句首。
（2）It is said /reported…结构中的主语从句不可提前。例如：
正确表达：It is said that President Jiang will visit our school next week.
错误表达：That President Jiang will visit our school next week is said.
（3）It happens/occurs…结构中的主语从句不可提前。例如：
正确表达：It occurred to him that he failed in the examination.
错误表达：That he failed in the examination occurred to him.
（4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如：
正确表达：It doesn’t matter whether he is wrong or not.
错误表达：Whether he is wrong or not doesn’t matter.
（5）含主语从句的复合句是疑问句时，主语从句不可提前。例如：
正确表达：Is it likely that it will rain in the evening
错误表达：Is that will rain in the evening likely
4. what 与that 在引导主语从句时的区别
what 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：
a) What you said yesterday is right.
b) That she is still alive is a consolation
二．宾语从句
宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词 (及物动词) 或介词之后。
1. 作动词的宾语
(1) 由that引导的宾语从句(that 通常可以省略), 例如：
I heard that be joined the army. 我听说他参军了。
(2) 由what, whether (if) 引导的宾语从句，例如：
a) She did not know what had happened.　她不知道发生了什么。
b) I wonder whether you can change this note for me.　我想知道你是否能帮我改一下笔记。
(3) 动词＋间接宾语＋宾语从句。例如：
She told me that she would accept my invitation.　她对我说她会接受我的邀请。
2. 作介词的宾语，例如：
Our success depends upon how well we can cooperate with one another.　我们的成功取决于我们之间的合作。
3. 作形容词的宾语，例如：
I am afraid (that) I’ve made a mistake.　我恐怕我已经犯了一个错误。
注意：that 引导的从句常跟在下列形容词后作宾语：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以将此类词后的that 从句的看作原因状语从句。
4. it 可以作为形式宾语
it 不仅可以作为形式主语，还可以作为形式宾语而真正的宾语that 从句则放在句尾，特别是在带复合宾语的句子中。 例如：
We heard it that she would get married next month. 我听说她下个朋就会结婚了。
5. 后边不能直接跟that 从句的动词
这类动词有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。如：
正确表达：I admire their winning the match.
错误表达：I admire that they won the match.
6. 不可用that从句作直接宾语的动词
有些动词不可用于“动词＋间接宾语＋that从句“结构中，常见的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如：
正确表达：He impressed the manager as an honest man.
错误表达：He impressed the manager that he was an honest man.
7. 否定的转移
若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。例如：
I don’t think this dress fits you well. 我认为这件衣服不适合你穿。
三. 表语从句
表语从句在复合句中作表语的名词性从句，放在系动词之后，一般结构是“主语＋连系动词＋表语从句”。可以接表语从句的连系动词有be, look, remain, seem等。引导表语从句的that常可省略。另外，常用的还有the reason is that… 和It is because 等结构。例如：
1) The question is whether we can make good preparation in such a short time.
2) This is why we can’t get the support of the people.
3) But the fact remains that we are behind the other classes.
4) The reason he is late for school is that he missed the early bus.
四. 同位语从句
同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能
同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：
1) The king’s decision that the prisoner would be set free surprised all the people.
2) The order that all the soldiers should stay still is given by the general.
2. 同位语在句子中的位置
同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。例如：
He got the news from Mary that the sports meeting was put off.
3. 同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：
1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。）（第一个that引导的从句是定语从句，that在从句中作宾语）
2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）

第三章 高中英语语法中的省略现象
　　在英语语言中，为了使语言简洁明了，重点突出或上下文紧密相连，可以省去某些句子成分而保持句子愿意不变，这种语言现象称之为省略。现就英语中的种种省略现象分析如下：
一、并列复合句中的省略
在并列句中后边的分句可以省略与前边分句中相同的成分。如：
a) The boy picked up a coin in the road and (the boy ) handed it to a policeman. 这个男孩在马路上拾起一枚硬币并把他交给了警察。
b) Your advice made me happy but(your advice made) Tom angry .你的建议使我高兴但使汤姆生气。
c) Tom must have been playing basketball and Mary (must have been)doing her homework. 汤姆肯定一直在打篮球，玛丽一直在写作业。
d) Gao Xiumin was born in 1959 and Fu Biao (was born) in 1963.高秀敏出生于1959年，傅彪出生于1963年。
二、主从复合句中的省略
1．状语从句中的省略
　　一般说来省略现象多出现在下列五种状语从句中：由 when ,while ,as ,before, after , till, until, once等引导的时间状语从句；由whether ,if , unless 等引导的条件状语从句；由though , although ,even if ,whatever等引导的让步状语从句；由 as ,than 等引导的比较状语从句；由as, as if , as though 等引导的方式状语从句。上述状语从句在省略时应遵循下面原则：
1) 当状语从句的主语与主句的主语一致时，可以省略状语从句的主语和系动词be，这时从句中可出现如下结构：(1) 连词（as, as if , once）+ 名词; (2) 连词（ though, whether , when）+形容词；(3) 连词(whether, as if ,while )+介词短语；(4) 连词(when , while , though )+ 现在分词； (5) 连词(when ,if ,even if ,unless ,once ,until, than , as ) + 过去分词； (6) 连词(as if ,as though ) + 不定式。如：
a) Once (he was)a worker ,Pang Long now becomes a famous singer .庞龙曾经是个工　人，现在变成一位著名的歌手。
b) Work hard when (you are) young ,or you'll regret.趁年轻要努力学习，要不然你会后悔的。
c) He looked everywhere as if (he was)in search of something .他到处看似乎在找什么东西。
d) While (he was) holding talks with President Hu Jintao ,US President George W. Bush thanked China for its important role in the Six-Party Talks.美国总统布什在与胡锦涛主席会谈时，感谢中国在六方会谈中起的重要作用。
e) The exhibition is more interesting than (it was) expected .这次展览比被预料的有趣的多。
f) Olympic gold medallist hurdler Liu Xiang opened his lips as if (he were) to speak。奥林匹克金牌获得者跨栏运动员刘翔张开嘴好像要说什么。
注意：
1) 当从句的主语和主句的宾语一致时，间或也有这样的省略,如：
Her father told her to be careful when (she was)crossing the street.当她过马路时父亲告诉她要当心。
2) 当从句的主语是 it，谓语动词中又含有系动词be 时 ，可以把it和系动词be一起省略。此时构成连词(if , unless ,when , whenever)+形容词的结构。如：

第四章 主谓一致
主谓一致(Subject- Verb Agreement)，指”人称”和”数方面的一致关系.如: He is going abroad. They are playing football.　可分为:语法一致, 内容一致, 就近一致.
(一) 语法一致原则: 即主语为单数,谓语用单数,主语为复数,谓语也用复数. 以下为注意事项:
1. 单数主语即使后面带有with , along with, together with, like(象), but (除了),except, besides, as well as, no less than, rather than(而不是), including, in addition to 引导的短语, 谓语动词仍用单数.
如: Air as well as water is matter. 空气和水都是物质.
No one except two servants was late for the dinner. 除了两个仆人外, 没有一个人迟来用餐。
2. 用and连接的并列主语,如果主语是同一个人,同一事,同一概念, 谓语动词用单数, 否则用复数. 如:
The poet and writer has come. 那位诗人兼作家来了.(一个人)
A hammer and a saw are useful tools. 锤子和锯都是有用的工具. (两样物)
用and连接的成对名词习惯上被看成是一个整体, 如:bread and butter(黄油抹面包), knife and fork(刀叉)等作主语时, 谓语动词用单数。
3. 不定式(短语), 动名词(短语), 或从句作主语时, 谓语动词用单数. 如:
Serving the people is my great happiness.
为人民服务是我最大的幸福.
When we’ll go out for an outing has been decided.

Many a boy likes playing basketball. 许多男生都喜欢打篮球.
More than one student was late. 不只一个学生迟到
More persons than one come to help us. 不止一个人来帮助我们。
7. none 做主语时,谓语动词可用单数, 也可用复数; 但在代表不可数的东西时总是看作单数,因而谓语动词要用单数. 如:

8. 名词如: trousers, scissors, clothes, goods, glasses 等作主语时, 谓语动词必须用复数. 如:

The injured were saved after the fire.
(三) 就近原则
1. 由here, there, where 等引导的倒装句中, (有时主语不止一个时)谓语动词与靠近它的主语在数上一致.如:
Here comes the bus 公共汽车来了.
Here is a pen and some pieces of paper for you. 给你一支钢笔和几张纸。
Where is your wife and children to stay while you are away
你不在这儿的时候, 你爱人和孩子在哪儿呆呢？

典型例题
The chair looks rather hard, but in fact it is very comfortable to ___.　
A. sit　 B. sit on　 C. be seat　 D. be sat on
答案：B.　如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。
用作介词的to
to 有两种用法：一为不定式+动词原形； 一为介词+名词/动名词, to 在下面的用法中是第二种，即to+ 名词/动名词：admit to承认，confess to承认，be accustomed to 习惯于，be used to 习惯于，stick to 坚持，turn to开始，着手于，devote oneself to 献身于，be devoted to 致力于， look forward to 盼望，pay attention to
注意
省to 的动词不定式
1) 情态动词 ( 除ought 外，ought to)：
2) 使役动词 let, have, make：
3) 感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后作宾补，省略to。
　
注意
在被动语态中则to 不能省掉。
I saw him dance. =He was seen to dance.
The boss made them work the whole night.=They were made to work the whole night.
4) would rather，had better：
5) Why… / why not…：
6) help 可带to，也可不带to, help sb (to) do sth：
7) but和except：but前是动词do时，后面出现的动词用不带to的动词不定式。
8) 由and, or和than连接的两个不定式，第二个to 可以省去：
9) 通常在discover, imagine, suppose, think, understand等词后，可以省去to be：He is supposed (to be) nice.　他应该是个好人。举例：He wants to move to France and marry the girl. He wants to do nothing but go out. 比较：He wants to do nothing but go out. He wants to believe anything but to take the medicine.
典型例题
1) ---- I usually go there by train.　
---- Why not ___ by boat for a change 　
A. to try going　 B.　trying to go　 C.　to try and go　 D.　try going　　
答案：D. why not 后面接不带to 的不定式，因此选D。
2) Paul doesn't have to be made ___. He always works hard.　
A. learn　 B. to learn　 C. learned　 D. learning
答案：B. make后接不带to 的动词不定式，当其用于被动时，to 不可省略。

4) The boy wanted to ride his bicycle in the street，but his mother told him ____.　
A. not to　　B. not to do　　C. not do it D. do not to

5) The patient was warned ___ oily food after the operation.
A. to eat no　 B. eating not　 C. not to eat　D. not eating
答案：C。warn一词要求后用不定式，此处为不定式的被动，否定形式为be warned not to do。

第六章 倒装结构
一　全部倒装
　全部倒装是指将句子中的谓语动词全部置于主语之前。此结构通常只用与一般现在时和一般过去时。常见的结构有：
　1. here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。例如：
　　1) There goes the bell.　铃声渐渐消失了。
　　2) Then came the chairman.　然后主席就来了
　　3) Here is your letter.　这是你的信。
　2. 表示运动方向的副词或地点状语置于句首，谓语表示运动的动词。例如：
　　1) Out rushed a missile from under the bomber.　轰炸机下面发出了一颗导弹。
　　2) Ahead sat an old woman.
　注意：上述全部倒装的句型结构的主语必须是名词，如果主语是人称代词则不能完全倒装。例如：
　　1) Here he comes. 他来了。　　
2) Away they went.　他们走了。
二　部分倒装
　 部分倒装是指将谓语的一部分如助动词或情态倒装至主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did，并将其置于主语之前。
　1.　句首为否定或半否定的词语，如no, not, never, seldom, little, hardly, at no time, in no way, not until… 等。例如：
　　1) Never have I seen such a performance. 我从来没看过这样的表演。
　　2) Nowhere will you find the answer to this question.　你在哪儿都不会找到这个问题的答案。
　　3) Not until the child fell asleep did the mother leave the room.　妈妈直到孩子睡着才离开房间。
　注意：当Not until引出主从复合句，主句倒装，从句不倒装。
　注意： 如否定词不在句首不倒装。例如：
　　1) I have never seen such a performance.我从来没看过这样的表演。
　　2) The mother didn't leave the room until the child fell asleep.妈妈直到孩子睡着才离开房间。
　2.　带有否定意义的词放在句首，语序需要部分倒装。常见的词语有： not , never , seldom , scarcely , barely , little , at no time , not only , not once , under on condition , hardly … when , no sooner …than …等。例如：
　 1) Not only did he refuse the gift, he also severely criticized the sender.　他不仅拒收了礼品，还狠狠批评了送礼的人。
　 2) Hardly had she gone out when a student came to visit her. 她刚要出门时有个学生来找她。
　 3) No sooner had she gone out than a student came to visit her.　她刚要走时一个学生来看她。
　注意：只有当Not only… but also连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Not only… but also仅连接两个并列词语，不可用倒装结构。例如：
　 Not only you but also I am fond of music.　我和你都喜欢音乐。
3.　表示"也"、"也不" 的so, neither, nor放在句首时，句子作部分倒装。例如：
　 1) Tom can speak French. So can Jack.　Tom能说法语，我也能。
2) If you won't go, neither will I.　如果你不去，我也不去。
　 注意： 当so引出的句子用以对上文内容加以证实或肯定时，不可用倒装结构。意为"的确如此"。例如：
　 1) Tom asked me to go to play football and so I did. Tom让我去踢足球，我去了。
　 2) ---It's raining hard.　　　---So it is.　---雨下得很大。　---的确很大。
　4.　only放在句首，强调状语（副词，介词短语或状语从句等），全句语序要部分倒装。例如：
　 Only in this way, can you learn English well.你只有用这种方法才能学好英语。
　 Only after being asked three times did he come to the meeting.　他被请了三次才来开会。
　注意：如果句子为主从复合句，则主句倒装，从句不倒装
　 Only when he is seriously ill, does he ever stay in bed. 他只有病得非常严重时才会卧床休息。
　三　as, though 引导的倒装句
　 as / though引导的让步从句必须将表语或状语提前 （形容词, 副词, 分词, 实义动词提前）。此时应注意：1) 句首名词不能带任何冠词；2) 句首是实义动词, 其他助动词放在主语后。如果实义动词有宾语和状语,随实义动词一起放在主语之前。例如：
　　 Try hard as he will, he never seems able to do the work satisfactorily.　尽管他愿意努力工作，但是他好像从来都不能令他的工作満意。
　注意:　让步状语从句中，有though，although时，后面的主句不能有but，但是 though 和yet可连用。
　四　其他部分倒装
　1. so… that 句型中的so 位于句首时，需倒装。例如：
　　 So frightened was he that he did not dare to move an inch.　他害怕得动都不敢动。
　2.　在某些表示祝愿的句型中，例如：
　　May you all be happy.　望大家开心愉快。
　3.　在虚拟语气条件句中从句谓语动词有were, had, should等词，可将if 省略，把 were, had, should 移到主语之前，采取部分倒装。例如：
　 Were I you, I would try it again.　如果我是你，我就再试一次。
第七章 定语从句
　　定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，有时也可以修饰部分或整个句子。
　　被修饰的名词，词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
　　关系代词有：who, whom, whose, that, which, as。
　　关系副词有：when, where, why, how。
　　关系代词和关系副词放在先行词和定语从句之间，起连接作用，同时又可做定语从句的一个成分。当关系代词做宾语时可以省略。
　　定语从句中的谓语动词必须在人称上和数量上和先行词保持一致。
　　定语从句分为限制性定语从句和非限制性定语从句。
1 、关系代词引导的定语从句
1) who, whom, that 这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
Is he the man who/that wants to see you （who/that在从句中作主语）
He is the man whom/ that I saw yesterday.（whom/that在从句中作宾语）
2) whose 用来指人或物，（只用作定语，若指物，它还可以同of which互换），例如：　
Please pass me the book whose (of which) cover is green.　
3) which, that 它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
A prosperity which / that had never been seen before appears in the countryside.（which / that在句中作宾语）
The package (which / that) you are carrying is about to come unwrapped. (which / that在句中作宾语)
关系代词that和which 都可以指物，that 和Who 都可以指人，其用法区别：
不用that的情况：
a) 在引导非限定性定语从句时
(错)The tree, that is four hundred years old, is very famous here.
b) 介词后不能用
We depend on the land from which we get our food.
c) 多用who 的情况
①关系代词在从句中做主语
A friend who helps you in time of need is a real friend.
②先行词为those, people 时
Those who were either fools or unfit for their offices could not see the cloth.
③先行词为all, anyone, ones, one 指人时
One who doesn't work hard will never succeed in his work.
④在There be句型中
There is a stranger who wants to see you.
⑤在被分隔的定语从句中
A new teacher will come tomorrow who will teach you German.
⑥在有两个定语从句的句子中，其一用who，其二用that,但若先行词后接两个以上的并列定语从句时，后一个必须重复前一个关系代词。
The student who was praised at the meeting is the monitor that is very modest and studies very hard.
There is a teacher who is always ready to help others and who enjoys what he does.
2) 只能用that作为定语从句的关系代词的情况
a)在不定代词，如：anything, nothing, everything, all, much, few, any, little等作先行词时，只用that，不用which。
All that is needed is a supply of oil.
Finally, the thief handed everything that he had stolen to the police.　
b)先行词有the only, the very, the just修饰时，只用that。　
He is the very man that helped the girl out of the water.
c)先行词为序数词(the last)、数词、形容词最高级时，只用that。
The first English book that I read was "The Prince and the Pauper" by Mark Twin.
d)先行词既有人，又有物时。
He talked about the teachers and schools that he visited.
e)当主句是以who 或which 开始的特殊疑问句时，用that 以避免重复。
Who is the person that is standing at the gate.
f)关系代词在从句中做表语
He is not the man that he used to be.
2 、关系副词引导的定语从句
关系副词可代替的先行词是时间、地点、方式或理由的名词，在从句中作状语。
关系副词when, where, why, how的含义相当于"介词+ which"
