从句可分为：
Ø 名词性从句à 主语从句、宾语从句、表语从句、同位语从句
Ø 形容词性从句à定语从句
Ø 副词性从句à状语从句
v 常考的关系代词：that; which; who/whom/whose; where; when; what; as。
v 常见的同位语从句现行词（that之前的抽象名词）：fact, idea, news, hope, conclusion, evidence, opinion, problem, thought, understanding„
v 常用的引导词
时间状语从句：while; when; before; whenever; as; after; till; until; since; once; ever since; as/so long as; as soon as; no sooner„ than; hardly„ when; scarcely/barely„ when; the moment/minute/instant; on (the point of) doing„
地点状语从句：where; wherever
原因状语从句：because; since; as; seeing that; （更多外语考试资讯尽在http://waiyu.kaoshibaike.com）considering that; now that; in that; for fear that; lest; owing to the fact that; because of the fact that; due to the fact that„
方式状语从句：as; as if; as though; how; save that„
比较状语从句：as; than; as„ as; not so„ as; hardly„ than;
结果状语从句：so that; so„ that; such„ that; so as to„
条件状语从句：if; unless; in case; so long as; so far as; provided/providing/that; supposing; granted/granting that„; giving that„.
让步状语从句：though; although; even if; even though; whether; as; however; no matter (what, how, when); for all that; in spite of the fact that; granted that; regardless of the fact that„
状语从句的省略
这种省略从句主语的方式理论上需要满足以下两个条件：
第一、特定的状语从句引导词：although though even though when while if as
第二、从句主语和主句主语必须保持一致；
第三、从句的谓语必须是be动词，主语和be动词同进同出，
which 引导的定语从句结构
1）which是关系代词，which后面应该加缺主语或者宾语的句子，
在这个句子中，which要作成分，作主语或者宾语
2）in which+完整的句子
which在定语从句中作in的宾语，所以不能作后面句子的主语
3）名词+of which+谓语动词
of which来修饰名词，名词在定语从句中作主语，所以后面直接跟谓语动词
I have five books three of which are borrowed from Mary.
4）介词+ which +to do 其功能相当于定语从句。
The key with which to open the door is lost.
（更多外语考试资讯尽在http://waiyu.kaoshibaike.com）
5）定语从句的省略结构：
1． 如果that / which在定从中作 宾语，可以省略.
sub+vt+n+(which / that)+sub+vt
→s+vt+n+s+v
s+vt+n1+n2+vt
*当做题时，若发现两个名词在一起，但是似乎连不上，则一定省略that /
which，则动词为vt，做谓语。
6）定从的特殊省略
the way (in which) + 句子
the reason (why that)+句子 均为完整句
the time (that / when)+句子
I do remember the first time (that省) I ever heard the
1． 主谓一致（与插入语无关）
1主谓的分隔原则：主谓之间可以用定语从句或者省略的定语从句分隔。
2定语从句中的主谓一致：
3随前一致：
n. + together with n2
as well as
including
along with
with / of
accompanied with / by
4就近原则：n1 or n2 +v（就近原则）
either n1 or n2
5可数n1 and 可数n2+v(pl)
不可数n1 and 不可数n2+v(pl)
例外：war and peace is„ war and peace是一个整体
但是如果主语表示的是同一个概念，同一人，同一事的时候，谓语动词用单数，这种结构的特征是and连接的两个词只有一个冠词。
The iron and steel industry is very important to our country.
The head master and mathematical teacher is coming.
（更多外语考试资讯尽在http://waiyu.kaoshibaike.com）
The head master and the mathematical teacher are coming.
类似的还有：law and order bread and
butter black and white
To love and to be loved is …
A lawyer and a teacher are…
A lawyer and teacher is …
6随后原则：not A but B / not only A but also B+v.(与B一致)
7百分比结构：most , half , rest , some , majority , one+persent
of+n1+v.（由n1决定）
8倒装结构的主谓一致：
a）There be +n 由名词决定动词
b）Among , between等介词位于句首引起倒装结构：
Among / Between „+系动词+n. （由名词决定动词）
9The+adj的主谓一致：
a）当表示“一类人”，
b）当表示某一抽象概念时
情态动词所表达的可能性程度：must/can't should/shouldn't might/may (not)
另外两个"类情态词的形式："need/needn't; have to/don't have to
最自然的虚拟状态：由should/would+原型时态（不含时间只含状态）
本质上是过去将来时：即，时间固定在过去将来，状态不同：一般、进行、完成、完成进行。 这时"虚拟语气"的产生往往是因为我们要表达"本来应该„„"（而现在却还没有„„） （本来可以„„，本来能„„）
I should go! („ but I'm still here!) (一般)
I should be working now! (进行)
I should have practiced more (than I did)! (完成)
我应该多多练习！（言下之意，现在我练习得不多。）
I shouldn't dream away my time too much! (完成的否定)
(actually I did dream away my time too much!)
It shouldn't have been leaking for such a long time! (完成进行)
I may/might/could have finished! (完成)
一些常见的句型中，就会出现这种虚拟语气，而处于从句之中，should 常常被省略掉 o suggest, advise, propose, recommend, plan;
o demand, order, direct, arrange, command, decide;
o require, request;
o think, expect, believe, insist, suspect.
由于他们的含义中包含"建议，假设，应该"这类的含义，所以，由他们引起的从句中，就会包含有should+原型时态构成的虚拟语气。
这些动词（以及他们的名次形式，分词形式）引起的从句还有其他的变形：
主语从句，表语从句，同位语从句
It's suggested that…
My suggestion is that…
The only suggestion that...
The only suggestion I can give you now is that…
一些形容词引起的表语从句中，也会有同样的情况
important; necessary; essential
It's natural ; strange;（更多外语考试资讯尽在http://waiyu.kaoshibaike.com） incredible that
a pity; a shame; no wonder
由lest, for fear that, in case 引起的从句中多使用should
表达与事实相反
1. 与现在相反：使用[过去时]：
I wish I were not here! (一般现在 一般过去)
Suppose we were not here.
He loved me as if I were his own son. (一般现在 一般过去)
Hope I weren't always losing things! (现在进行 过去进行)
If only/If I hadn't been there! (现在完成 过去完成)
What if I hadn't been waiting right here! (现在完成进行 过去完成进行)
常考句型：It's (high) time (that)„; would rather (that)„
这两个从句，只能表达对现在的看法，所以，从句中只有一般过去时。
2. 与过去相反：过去完成时；
How nice it is if I had past the test!
How nice it is if I had slept a little more this morning!
3. 与将来相反？将来的事情没有发生，所以只能推测。
If it rains tomorrow, we'll have to stay one day more.
不过，由于可以用be to表示将来；所以，虚拟语气中经常出现were to；也是CET-4的常考语法点。
虚拟条件句
o if 部分，做一个与事实相反的假设（所以只有一般过去和过去完成）；
o 主句部分，这是表示基于这个假设的推测，一般使用情态动词would，少数情况下使用could/might/may。
o 注意：两个部分之间，是有逻辑关系，而在两部分的谓语动词时态上，没有必然的联系。
注意，虚拟条件句中的if可以省略，造成were/had提前，产生倒装。 隐含的非真实条件
What would you do with 50 thousand dollar?
How could I be happy without you?
除了条件状语从句之外，原因状语从句也会出现虚拟语气。
o 由in order that, so that引起的从句，肯定的时候可以使用may/might; can/could; 否定的时候，多用shouldn't;
whoever, whatever, no matter what引起的从句中，多用may+
一．不定式：
一）不定式的常考形式：
1)
一般形式：He decided to work harder in order to catch up with the others.
被动形式: He preferred to be assigned some heavier work to do.
语法功能：
表示与谓语动词同步发生
2)
完成形式：He pretended not to have seen me.
被动形式：The book is said to have been translated into many languages.
语法功能：表示发生在谓语动词之前
二）不定式常考的考点：
1）不定式做定语----将要发生
2）不定式做状语----目的
3）不定式充当名词功能---To see is to believe.
三)不定式的省略
1)感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel
+ do 表示动作的完整性，真实性；
+ doing
表示动作的连续性，进行性
I saw him work in the garden yesterday.
昨天我看见他在花园里干活了。(强调"我看见了"这个事实)
I saw him working in the garden yesterday.
昨天我见他正在花园里干活。（强调"我见他正干活"这个动作）
v
感官动词后面接形容词而不是副词：The cake tastes good; It feels comfortable.
2) 使役动词
have bid make let 等词后不定式要省略但同1)一样被动以后要还原to
I ‘d like to ha（更多外语考试资讯尽在http://waiyu.kaoshibaike.com）ve John do it.
I have my package weighed.
Paul doesn’t have to be made to learn.
3) help
help sb do
help sb to do
help do
help to do
四)有些动词后只跟不定式如：
want，wish，hope，manage，promise，refuse，pretend，plan， offer，decide，agree，expect
allow sb to do,
cause sb to do , permit sb to do, enable sb to do
force sb to do. be more likely to do
love to do
warn sb to do
be able to do
be
ambitious to do. begin to do . start to do
五) 有的时候to后面要接-ing形式
accustom (oneself) to; be accustomed to; face up to; in addition to; look forward to; object to; be reduced to; resign oneself to; be resigned to; resort to; sink to; be used to; be alternative to; be close/closeness to; be dedication/dedicated to; be opposition/opposed to; be similarity/similar to.
三、need/want 后的-ing形式具有被动的意思。其中，want不太常用。
He needs (a lot of) encouraging.
二. 动名词： 具有动作性特征的名词
1)是名词 seeing is believing
2)具有动词性特征可以带宾语 starving troops is necessary.
一)动名词的形式:
一般形式：I don't like you smoking.
完成形式：I regret not having taken your advice.
被动形式：This question is far from being settled.
二) 动名词常考的点
1)动名词做主语谓语动词为单数
2)在动名词和不定式中,做为介词的宾语是动名词
3)动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语. I would appreciate_______ back this afternoon．
A．you to call B．you call C．you calling D．you're calling（Key：C your calling 也对） I regret not having taken your advice.
4)有些词后只能接动名词
admit; appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can't help; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand...
另外还有一些接-ing形式的常用说法：
it's no good; it's no/little/hardly any/ use; it's not/hardly/scarcely use; it's worthwhile; spend
money/time; there's no; there's no point in; there's nothing worse than; what's the use/point...
5有些词后加不定式和动名词均可
remember, forget, try, st（更多外语考试资讯尽在http://waiyu.kaoshibaike.com）op, go on, cease, mean后面用不定式和-ing形式，意义截然不容。
I remembered to post the letters. (指未来/过去未来的动作)
I remembered posting/having posting the letters (我记得这个动作)
forgot与remember的用法类似。
I regret to inform you that„ 我很遗憾地通知你„
I regretted having left the firm after twenty years. 为了"二十年前的离开"而遗憾。
try to 努力 You really must try to overcome your shyness.
try –ing 试验 Try practicing five hours a day.
I mean to go, but my father would not allow me to. [打算、想]我想去，但我父亲不让我去。 To raise wage means increasing purchasing power. [意味着]赠加工资意味着增加购买力。 prefer的用法：
我宁愿在这里等。
I prefer to wait here. （所以啊，你不介意的话，我就等下去。）
I prefer waiting here.（我正在这里等，我就喜欢这么做。）
I prefer swimming to cycling. （这个句子里面就不能用不定式了。）
3 分词：
现在分词主动进行,过去分词被动状态
现在分词的形式:
1)一般式: Do you see the man talking to the dean（主任）? (与谓语动词同步发生)
2)完成形式：Not having made adequate preparations, they failed. (发生谓语动词之前)
3)完成被动形式：Having been adapted, the script seems perfect.( 发生谓语动词之前且表示被动)
过去分词
1) 过去分词表示被动：Fight no battle unprepared.
2)过去分词的进行形式：You'll find the topic being discussed everywhere. (强调正在被做) 这三种非谓语动词，都可以构成复合结构，非谓语动词所修饰的成分是这些非谓语动词的逻辑主语。他们之间的一致关系——主动还是被动，往往就是考点。独立主格结构中，要注意的是分词与他前面的逻辑主语之间的主动被动的关系。
一、有的动词其后可以跟动名词，例如：
--I really appreciate having time to relax.
--Have you considered getting a job abroad?
这些动词常见的有：admit, appreciate, avoid, break off, cease, commence, confess, consider, contemplate, continue, delay, deny, deserve, detest, dislike, dread, endure, enjoy, escape, excuse, face, (not) fancy, feel like, finish, forgive, give up, can"t help, imagine, involve, justify, leave off, mention, mind, miss, postpone, practice, put off, quit, recall, recommend, require, resent, resist, resume, risk, (can"t) stand, sugge（更多外语考试资讯尽在http://waiyu.kaoshibaike.com）st, take up, understand

--I can"t afford to buy her a new dress.
--Jack hates to miss the train.
这些动词常见的有：dread, hate, like, love, prefer, begin, cease, commence, continue, start, forget, remember, regret, choose, hope, intend, mean, plan, propose, want, wish, help, scorn, venture, ask, beg, decline, demand, offer, promise, refuse, swear, undertake, affect, claim, profess, afford, attempt, contrive, endeavor, fail, learn, manage, neglect, omit, try等。
三、有的动词其后既可以带不定式，也可以跟动名词，一定要注意所表示意思的区别。
1 全部倒装
是只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：Up went the plane = the plane went up.
1) here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
2) 表示运动方向的副词(back, down, off, up)或地点状语置于句首，谓语表示运动的动词。
注意：1) 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倒装。Here he comes. Away they went. 2) 谓语动词是be的时候，不能倒装。 Here it is. Here you are.
3） 形容词短语/分词短语位于句首，引起倒装
*typical of （更多外语考试资讯尽在http://waiyu.kaoshibaike.com）characteristic of *coinciding with + n
4） 表示地点范围的介词短语位于句首，谓语动词为系动词，一定引起倒装
In„（表语）+系动词+主，主同。
*在倒装句型答案中不能出现there
*常考介词要倒装：among between in at beneath
常考的系动词：be lie exist remain rest
部分倒装
1． 否定 adv 位于句首，引起倒装：not only, not until, hardly, scarcely,
seldom, rarely, no sooner„than
1） not until + 时间 + 主谓倒装，not until + 句子+主谓倒装
2） only+状语位于句首
only +ad.
从句可分为：
Ø 名词性从句à 主语从句、宾语从句、表语从句、同位语从句
Ø 形容词性从句à定语从句
Ø 副词性从句à状语从句
v 常考的关系代词：that; which; who/whom/whose; where; when; what; as。
v 常见的同位语从句现行词（that之前的抽象名词）：fact, idea, news, hope, conclusion, evidence, opinion, problem, thought, understanding„
v 常用的引导词
时间状语从句：while; when; before; whenever; as; after; till; until; since; once; ever since; as/so long as; as soon as; no sooner„ than; hardly„ when; scarcely/barely„ when; the moment/minute/instant; on (the point of) doing„

让步状语从句：though; although; even if; even though; whether; as; however; no matter (what, how, when); for all that; in spite of the fact that; granted that; regardless of the fact that„
状语从句的省略
这种省略从句主语的方式理论上需要满足以下两个条件：
第一、特定的状语从句引导词：although though even though when while if as
第二、从句主语和主句主语必须保持一致；
第三、从句的谓语必须是be动词，主语和be动词同进同出，
which 引导的定语从句结构
1）which是关系代词，which后面应该加缺主语或者宾语的句子，
在这个句子中，which要作成分，作主语或者宾语
2）in which+完整的句子
which在定语从句中作in的宾语，所以不能作后面句子的主语
3）名词+of which+谓语动词
of which来修饰名词，名词在定语从句中作主语，所以后面直接跟谓语动词
I have five books three of which are borrowed from Mary.
4）介词+ which +to do 其功能相当于定语从句。
The key with which to open the door is lost.
（更多外语考试资讯尽在http://waiyu.kaoshibaike.com）
5）定语从句的省略结构：
1． 如果that / which在定从中作 宾语，可以省略.
sub+vt+n+(which / that)+sub+vt
→s+vt+n+s+v
s+vt+n1+n2+vt
*当做题时，若发现两个名词在一起，但是似乎连不上，则一定省略that /
which，则动词为vt，做谓语。
6）定从的特殊省略
the way (in which) + 句子
the reason (why that)+句子 均为完整句
the time (that / when)+句子
I do remember the first time (that省) I ever heard the
1． 主谓一致（与插入语无关）
1主谓的分隔原则：主谓之间可以用定语从句或者省略的定语从句分隔。
2定语从句中的主谓一致：
3随前一致：
n. + together with n2
as well as
including
along with
with / of
accompanied with / by
4就近原则：n1 or n2 +v（就近原则）
either n1 or n2
5可数n1 and 可数n2+v(pl)
不可数n1 and 不可数n2+v(pl)
例外：war and peace is„ war and peace是一个整体
但是如果主语表示的是同一个概念，同一人，同一事的时候，谓语动词用单数，这种结构的特征是and连接的两个词只有一个冠词。
The iron and steel industry is very important to our country.

9The+adj的主谓一致：
a）当表示“一类人”，
b）当表示某一抽象概念时
情态动词所表达的可能性程度：must/can't should/shouldn't might/may (not)
另外两个"类情态词的形式："need/needn't; have to/don't have to
最自然的虚拟状态：由should/would+原型时态（不含时间只含状态）
本质上是过去将来时：即，时间固定在过去将来，状态不同：一般、进行、完成、完成进行。 这时"虚拟语气"的产生往往是因为我们要表达"本来应该„„"（而现在却还没有„„） （本来可以„„，本来能„„）
I should go! („ but I'm still here!) (一般)
I should be working now! (进行)

我应该多多练习！（言下之意，现在我练习得不多。）
I shouldn't dream away my time too much! (完成的否定)
(actually I did dream away my time too much!)
It shouldn't have been leaking for such a long time! (完成进行)
I may/might/could have finished! (完成)
一些常见的句型中，就会出现这种虚拟语气，而处于从句之中，should 常常被省略掉 o suggest, advise, propose, recommend, plan;
o demand, order, direct, arrange, command, decide;
o require, request;
o think, expect, believe, insist, suspect.
由于他们的含义中包含"建议，假设，应该"这类的含义，所以，由他们引起的从句中，就会包含有should+原型时态构成的虚拟语气。
这些动词（以及他们的名次形式，分词形式）引起的从句还有其他的变形：
主语从句，表语从句，同位语从句
It's suggested that…
My suggestion is that…
The only suggestion that...
The only suggestion I can give you now is that…
一些形容词引起的表语从句中，也会有同样的情况
important; necessary; essential

I wish I were not here! (一般现在 一般过去)
Suppose we were not here.
He loved me as if I were his own son. (一般现在 一般过去)
Hope I weren't always losing things! (现在进行 过去进行)
If only/If I hadn't been there! (现在完成 过去完成)
What if I hadn't been waiting right here! (现在完成进行 过去完成进行)
常考句型：It's (high) time (that)„; would rather (that)„
这两个从句，只能表达对现在的看法，所以，从句中只有一般过去时。
2. 与过去相反：过去完成时；
How nice it is if I had past the test!
How nice it is if I had slept a little more this morning!
3. 与将来相反？将来的事情没有发生，所以只能推测。
If it rains tomorrow, we'll have to stay one day more.
不过，由于可以用be to表示将来；所以，虚拟语气中经常出现were to；也是CET-4的常考语法点。
虚拟条件句
o if 部分，做一个与事实相反的假设（所以只有一般过去和过去完成）；
o 主句部分，这是表示基于这个假设的推测，一般使用情态动词would，少数情况下使用could/might/may。

注意，虚拟条件句中的if可以省略，造成were/had提前，产生倒装。 隐含的非真实条件
What would you do with 50 thousand dollar?
How could I be happy without you?
除了条件状语从句之外，原因状语从句也会出现虚拟语气。
o 由in order that, so that引起的从句，肯定的时候可以使用may/might; can/could; 否定的时候，多用shouldn't;

表示与谓语动词同步发生
2)
完成形式：He pretended not to have seen me.
被动形式：The book is said to have been translated into many languages.
语法功能：表示发生在谓语动词之前
二）不定式常考的考点：
1）不定式做定语----将要发生
2）不定式做状语----目的
3）不定式充当名词功能---To see is to believe.
三)不定式的省略
1)感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel
+ do 表示动作的完整性，真实性；
+ doing
表示动作的连续性，进行性
I saw him work in the garden yesterday.
昨天我看见他在花园里干活了。(强调"我看见了"这个事实)
I saw him working in the garden yesterday.
昨天我见他正在花园里干活。（强调"我见他正干活"这个动作）
v
感官动词后面接形容词而不是副词：The cake tastes good; It feels comfortable.
2) 使役动词
have bid make let 等词后不定式要省略但同1)一样被动以后要还原to

cause sb to do , permit sb to do, enable sb to do
force sb to do. be more likely to do
love to do
warn sb to do
be able to do
be
ambitious to do. begin to do . start to do

三、need/want 后的-ing形式具有被动的意思。其中，want不太常用。
He needs (a lot of) encouraging.
二. 动名词： 具有动作性特征的名词
1)是名词 seeing is believing
2)具有动词性特征可以带宾语 starving troops is necessary.
一)动名词的形式:
一般形式：I don't like you smoking.
完成形式：I regret not having taken your advice.
被动形式：This question is far from being settled.
二) 动名词常考的点
1)动名词做主语谓语动词为单数
2)在动名词和不定式中,做为介词的宾语是动名词
3)动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语. I would appreciate_______ back this afternoon．
A．you to call B．you call C．you calling D．you're calling（Key：C your calling 也对） I regret not having taken your advice.
4)有些词后只能接动名词
admit; appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can't help; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand...
另外还有一些接-ing形式的常用说法：
it's no good; it's no/little/hardly any/ use; it's not/hardly/scarcely use; it's worthwhile; spend
money/time; there's no; there's no point in; there's nothing worse than; what's the use/point...
5有些词后加不定式和动名词均可
remember, forget, try, st（更多外语考试资讯尽在http://waiyu.kaoshibaike.com）op, go on, cease, mean后面用不定式和-ing形式，意义截然不容。
I remembered to post the letters. (指未来/过去未来的动作)
I remembered posting/having posting the letters (我记得这个动作)
forgot与remember的用法类似。
I regret to inform you that„ 我很遗憾地通知你„
I regretted having left the firm after twenty years. 为了"二十年前的离开"而遗憾。
try to 努力 You really must try to overcome your shyness.
try –ing 试验 Try practicing five hours a day.
I mean to go, but my father would not allow me to. [打算、想]我想去，但我父亲不让我去。 To raise wage means increasing purchasing power. [意味着]赠加工资意味着增加购买力。 prefer的用法：
我宁愿在这里等。
I prefer to wait here. （所以啊，你不介意的话，我就等下去。）
I prefer waiting here.（我正在这里等，我就喜欢这么做。）
I prefer swimming to cycling. （这个句子里面就不能用不定式了。）
3 分词：
现在分词主动进行,过去分词被动状态
现在分词的形式:
1)一般式: Do you see the man talking to the dean（主任）? (与谓语动词同步发生)
2)完成形式：Not having made adequate preparations, they failed. (发生谓语动词之前)
3)完成被动形式：Having been adapted, the script seems perfect.( 发生谓语动词之前且表示被动)
过去分词
1) 过去分词表示被动：Fight no battle unprepared.
2)过去分词的进行形式：You'll find the topic being discussed everywhere. (强调正在被做) 这三种非谓语动词，都可以构成复合结构，非谓语动词所修饰的成分是这些非谓语动词的逻辑主语。他们之间的一致关系——主动还是被动，往往就是考点。独立主格结构中，要注意的是分词与他前面的逻辑主语之间的主动被动的关系。
一、有的动词其后可以跟动名词，例如：

二、有的动词其后可以带不定式作宾语，例如：

三、有的动词其后既可以带不定式，也可以跟动名词，一定要注意所表示意思的区别。
1 全部倒装
是只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：Up went the plane = the plane went up.
1) here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
2) 表示运动方向的副词(back, down, off, up)或地点状语置于句首，谓语表示运动的动词。
注意：1) 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倒装。Here he comes. Away they went. 2) 谓语动词是be的时候，不能倒装。 Here it is. Here you are.
3） 形容词短语/分词短语位于句首，引起倒装
*typical of （更多外语考试资讯尽在http://waiyu.kaoshibaike.com）characteristic of *coinciding with + n
4） 表示地点范围的介词短语位于句首，谓语动词为系动词，一定引起倒装
In„（表语）+系动词+主，主同。
*在倒装句型答案中不能出现there
*常考介词要倒装：among between in at beneath
常考的系动词：be lie exist remain rest
部分倒装
1． 否定 adv 位于句首，引起倒装：not only, not until, hardly, scarcely,
seldom, rarely, no sooner„than
1） not until + 时间 + 主谓倒装，not until + 句子+主谓倒装
2） only+状语位于句首
only +ad.
