高中语法专项二
倒装
所谓倒装也就是谓语动词出现在主语之前的现象。其中谓语动词全部放在主语之前的叫作全部或完全倒装；把谓语中的助动词或情态动词放在主语之前的则称为部分倒装。
一、全部倒装。
1． 由here，there，now, then + come/go …时。如：
There goes the bell! Now comes your turn.。
2．副词out，in, into, away, up, down等置于句首时。如：
Out jumped a tiger from behind a rock. In came an old man with a long white beard.
3. 当地点状语置于句首时。如：
At the corner of the street stands a newly-opened tea house.
On the wall hang two pictures.
但当主语为代词时，不用倒装结构。
Here they are.
Out they went into the forest.
Away they rushed when they saw some enemy soldiers running along.
二、部分倒装
1．在口语中，用在以so，neither，nor引起的缩略答语中，即So do sb./ Neither(nor) do sb.结构。(So do sb: 两者比较，也是如此；So sb does: 同一个人再次确定，确实如此)
2．only + 状语放句首。如：
1） Only when he reached school did he realize that he left his textbook at home.
2） Only then did she see her mother.
3） Only in this way can we improve our English.
3．表否定意义的成分 little; few; seldom; neither; nor; no; not; never; hardly; scarcely（很少）放在句首时。如：
1) Never shall I forget the day when I met Mr.Wang in the countryside.
2)As she is busy writing an important article, seldom does she watch Tv.
3)Hardly does the hibernating animal make any movement and need any food in winter.
4)Little did I expect to meet him on such an occasion.
4．几个结构：
1) Not only+倒… but also+顺
Not only is he a diligent student, but also he is a warmhearted helper.
2) Neither+倒… nor +顺
Neither did they remain silent nor any one of them shout at the top of his voice.
3)Either +倒… or +顺
Either will he choose to stay or go with the big group.
4)Not until置于句首时， Not until+时间+肯定句的部分倒装（没有not ）
Not until he lost his health did he realize what good health meant.（倒装在后）
5．在虚拟语气结构中，当if省略时, 后面的had, should ，were提到句首，剩下部分不变。
If he had known about it , he would have come to the meeting yestersay. = Had he known about it, …
If it were to rain tomorrow, we wouldn’t have the meeting. = Were it to rain tomorrow, …
6. 在so + adj/adv + that…结构中，当so + adj/adv置于句首时。如：
So louldly did he speak that everybody could hear him clearly.
7. 在Scarcely / Hardly had …when和No sooner had… than(刚…就…)的结构中。如：
Hardly had I got back when I started cooking.
No sooner had we sat down than he found it was time to go.
8. 在频度状语often, always, many a time等开头的句子中
Often did we warn them not to do so.
Many a time has she helped me with my English.
9. 在as（尽管）引导的让步状语从句中 = Though／Although。。。(此时不可用 As…, 因为as放句首时只能表示因为或是当。。。的时候)
Young as he is, he knows a lot. Child as he is, he knows a lot.
Hard as he works, he is not good at maths.
放中间时as和though可以替换, 注意名词前提时不带任何冠词。
