2)句子为主从复合句,从句倒装,主句不倒装

(2)就远原则:with / together with / as well as / but / except / no less than / like等,谓语动词与主语前的主语一致

时态条件从句用一般现在时,主句用shall / will + 动词原形(不可用be going to

(2)非真实条件句,基本特点是时态退后

1)表示同现在事实相反的假设

从句用一般过去时,主句用should / would + 动词原形

If they were herethey would help you.

2)表示同过去事实相反的假设

从句用过去完成时,主句用would / should have + 过去分词

2)Wish sb to do // wish to do

15. 名词性从句

连接词:thatwhetherif(不充当任何成分);连接代词:whatwhateverwhowhoeverwhomwhichwhose;连接副词:whenwherehowwhy

位于介词后的连词或是引导同位语从句的连词不可省略

Whetherifwhether引导主语从句且置于句首whether引导表语从句whether从句作介词宾语whetheror notwhetherif 不可替换

【注】it appears that 似乎……;it happens that碰巧……;

it occured to me that 突然想起……

16. 定语从句

whose=of which when = on / in which why = for whichwhere=in which

1)限制性定语从句和非限制性定语从句:限制性定语从句是先行词不可缺少的部分,去掉它主句意思往往不明确;非限制性定语从句是先行词的附加说明,去掉了也不会影响主句的意思,它与主句之间通常用逗号分开当先行词是专有名词或物主代词和指示代词所修饰时

【注】that why 不能引导非限制性定语从句

2as which引导的非限制性定语从句,as一般置于句首,which置于居中

【注】as代表整个主句且在从句中作主语时,谓语动词必须是be动词

(3)What 特指=the thing which& whatever泛指=anything

(4)只能用that的情况

1)there be 句型

2)不定代词anythingnothinganylittlefew等作先行词

3)先行词有the onlythe very修饰时

4)先行词有序数词、数词、形容词最高级修饰时

5)先行词既有人也有物时

17. 状语从句

1)方式状语从句

asso…结构位于句首,这里的as有比喻的含义,意思是正如…,就像… eg. As water is to fishso air is to man.

as if/ as though引导状语从句多用虚拟语气,似乎,好像;当所说情况是事实或者实现的可能性较大时,用陈述语气

2)原因状语从句:assinceforbecause

Because语势最强,用来说明人们不知道的原因,常用来回答why的问题;当原因是显而易见的或是人们所熟知的,则用sinceas;如果是表示说话者的推断,则用for

(1)目的状语从句:so thatin order thatfor fear thatin caselest等词

(2)结果状语从句:sothat…、suchthat…引导

【固定搭配】so much / many / few / little such a lot of

(3)件状语从句:ifunless=if noton condition that…、as / so long as

(4)让步状语从句:thoughalthough引导,不能与but连用,可与yet连用

even if / though 即使;

whetheror 不管…都…;

no matter wh- // wh- + -ever

(5)时间状语从句中whenwhileaswhenas引导短暂性动作的动词;当从句的动作发生在主句动作之前,只能用when引导;表示随着时间的推移只能用as,如as the time goes on // as the day went on

(6)表示一……就……的句型:

as soon as / no soonerthan hardly / scarcely / barelywhen

No sooner had I got home than it began to rain.

18. 连词

(1)and & or:平行结构

连接祈使句或名词词组表示条件 One more effortand you'll succeed.

There is no air or water in the moon.

There is no air and no water on the moon.两否定词被看做是肯定结构

(2)althoughyet连用,但不与but连用

19. 情态动词

(1)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 ought 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。

(2)can be able to的区别

1)can只有现在式和过去式,be able to 可用于各种时态

2)表示成功做成某事时,只能用be able to,相当于manage to do

3)表示委婉的请求或者否定地推测/怀疑时,用could

He couldn't be a bad man.

(3)maymight的区别

might表示推测时,只是可能性比may小,都表示没有把握地推测

may / might as well 不妨 If that is the casewe may as well try.

(4)musthave to的区别:

must表示说话人的主观看法,have to 表示客观需要

否定句中mustn't 表示禁止;don't have to 表示不必

表示要求、命令时,shouldhad bettermust语气渐强

【引申】must用在肯定句中表示较有把握地推测,意为“一定”,有must be / must be doing / must have done / must have been doing

否定推测用can't

(5)should have done / ought to have done 表示本应做某事而事实上没有做,其否定形式表示本不该做某事却做了

(6)needn't have done 本没必要做某事而做了

(7)would like to have done 本打算做某事但事实上没有做

20. 特殊句型

1)there is no point in doing sth 做……是无济于事的/没有什么作用

there is very little/not much point in doing sthpoint做目的、用处讲,不可数】

2)have difficulty/ trouble in doing sth

3)keep sb busy (in) doing sth //be busy with sth

4)feel like doing sth

21. 平行结构

当两个或两个以上的同等成分(主谓宾定状补)并列时,要求它们结构或词性相同,即名队名,介对介,分对分,句对句等

使役动词后的宾语补足语

常见的使役动词有:havemakegetleaveletsetwant,其宾语补足语有名词、形容词、介词短语、动词不定式和分词等

makelethave动词不定式不用to

强调句型 it is +被强调部分(主//状语)+that+句子其他部分

It is what you will do that is essential.

It is only when one is ill that one realize the value of health.

【注】被强调的部分是表示人的名词,可用who代替;表示物的名词可用which代替;如果是原因状语从句,只能用because引导,而不能用sinceaswhy

有三类句子不能被强调,表语/谓语(加助动词)/thoughalthoughwhereas引导的从句

It is whereas he prefers pop song that I like classical music. ()

I like classical music whereas he prefers pop songs. ()
