倒装的实质：语序（谓语+主语） 倒装的作用：强调
倒装的分类：全部倒装和半倒装（必考点） 谓语： 1. be+表语
2.情态动词+动词原形 3.实义动词
什么情况下用半倒装呢？
1. 表示否定意味的副词位于句首，采取全倒装。
Eg:（1）.She hardly stays up too late on weekend.
半倒：Hardly does she stay up too late on weekends.
（2）. She at no time goes to the bar. 半倒：At no time does she go to the bar. 2. 主倒从不倒
（1）. Hardly/ scarcely...when=no sooner... than
将hardly/scarcely/no sooner 位于句首，主句
半倒装，从句不变。
Eg: I had hardly entered the room when I heard the ring.
半倒：Hardly had I entered the the room when I heard the ring.
总结：Hardly/Scarcely/No sooner +had +主语+done+....when/than....
(2).only +副词/介词短语/时间状语从句， 主句（be/情态动词/助动词+主语+表语/动词原形）
Eg: Only in this way can we protect the environment.
Eg: Only when she comes back do I know the news.
3. 前倒后不倒
（1）So/such...that... “如此。。。以至于。。。” Eg: she is so beautiful that I can not breathe. 半倒： So beautiful is she that I can not breathe.
总结：So/such +adj./adv.+be/情态动词/助动词+主语+其他+that 从句（不倒装） 真题：
So_________ that she has no time to rest. A. Busy she was B. Busy was she C. Was she busy D. She was busy
（2）Not only...but also... “不仅...而且。。。” Eg: i am not only lonely but also i miss you. Not only am I lonely but also i miss you. （3）Not ...but...“不是。。。而是。。。” Eg: it is not you dead but i am dead. 半倒：Not is it dead but i am dead. 4. as “尽管” 引导让步状语从句
结构：adj./adv./n.+as +主语+谓语，主句. V. +as +主语+would/could, 主句. Eg: Try as I could，I failed at last. Ugly as i am, i am gentle.
Strong as he is, he can not hold up her. Child as he is, he knows a lot. a / an /the 不能在名词前。
5. If 引导的虚拟条件句的半倒装（必考） 条件：if 从句中有had/were/should时， 可
以省略if,将had/were/should提到主语之前，其他成分不变。
eg: if I were a boy, i would drink beers with guys and chase after the girl.
==Were I a boy, i would drink beers with guys and chase after the girl.
Eg: if he had eaten the rice, he would have been fat.
==had he eaten the rice, he would have been fat.
Eg: if it should rain tomorrow, we would sleep. ==should it rain tomorrow, we would sleep. 6. 前面句子（肯定）， so+be/情态动词/助动词+主语。“也一样”
Eg: she can dance, so can I. She likes ice-cream, so do I. 前面句子（否定），neither/nor+be/情态动词/助动词+主语。“也不一样”
Eg: he can not sing, neither/nor can I.
注意：so/neither/nor +主语+be/情态动词/助动词 “的确如此”
