英语中什么时候用全倒装 什么时候用部分倒装 so…that… not only…but also…的句型中把so,not only提到句首 在从句中倒装还是在主句中倒装 请举例说明 谢谢
參考答案:倒装句之全部倒装
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：
1) here, there, now, then, thus等副词置于句首, 谓语动词常用be, come, go, lie, run。
There goes the bell.
Then came the chairman.
Here is your letter.
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。
Out rushed a missile from under the bomber.
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。
Here he comes. Away they went.
倒装句之部分倒装
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。
Never have I seen such a performance.
Nowhere will you find the answer to this question.
Not until the child fell asleep did the mother leave the room.
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。
I have never seen such a performance.
The mother didn't leave the room until the child fell asleep.
典型例题
1) Why can't I smoke here?
At no time___ in the meeting-room
A. is smoking permitted B. smoking is permitted
C. smoking is it permitted D. does smoking permit
答案A. 这是一个倒装问题。当否定词语置于句首以表示强调时，其句中的主谓须用倒装结构。 这些否定词包括no, little, hardly, seldom, never, not only, not until等。本题的正常语序是 Smoking is permitted in the meeting-room at no time.
2） Not until the early years of the 19th century ___ what heat is.
A. man did know B. man know C. didn't man know D. did man know
答案D. 看到Not until…的句型，我们知道为一倒装句，答案在C，D 中选一个。
改写为正常语序为，Man did not know what heat is until the early years of the 19th. 现在将not提前，后面就不能再用否定了,否则意思就变了。
