英语倒装句分为两种：
１、整个谓语在主语前的句子，叫完全倒装。
In came our English teacher.
There is a table in the room.
２、部分谓语（情态动词、主动词、连系动词）在前，谓语的主体部分仍在主语之后的句子,叫不完全倒装句/部分倒装。
Why did you do it like that?
Seldom have I been to Beijing.
一、完全倒装
1. There be 句型
there be 句子中，谓语是be, exist, live, lie 等表示状态的不及物动词。
动词后的名词为句子的主语。
句子的谓语应与最靠近它的主语相一致
There is nobody in the classroom.
There seems something wrong with my radio.
There happened an event last week.
There stands a temple on the top of the mountain.
2. 用于方位副词（here、there、now、out、in、then、up、down、away、over、off、back 等）开头的句子中。
Look, here comes the bus!
Out went the children.
The door opened and in came Mr. Smith, our headmaster.
Tips:
①当代词做句子的主语时,句子不能倒装。
②进行时不用于倒装！
Away they went. Back they fought.
Here he comes. Up it flew.
3. 方位介词短语位于句首时
On the top of the hill lies an old temple.
4. “分词+be+主语”
Walking at the head of the line was our teacher
Gone are the days when the Chinese people used foreign oil
Hanging on the wall was a clock made in Germany.
5. Such +be +主语
Such is what he said.
Such are his words

2. only + 状语放在句首,要部分倒装。

3. “Not only + 分句,but also + 分句”句型中的前一分句需要部分倒装

②. Hardworking as he was, he failed to pass the test again
③. Try as he might, he failed again
④. Hard as he works, he earns little.
8. so 表示“也一样”，neither，nor 表示“也不”，放在句首..
