1.疑问句和特殊疑问句要倒装
Are you cold?
Does he go to school by bike?
注意：若疑问词在句中作主语或主语的定语时，不倒装。
Who is your English teacher?
Whose father is a worker?

2.There be 句型
在There+助动词/情态动词+be+主语+地点/时间的句型中，主语在谓语be动词后面，因此这是倒装。
There was not an underground in Beijing before.
There are not many people who want to read this book..
There will be a basketball match this afternoon.
注意：这种倒装句在There seems/happened/used/lived/came to be等句型中也同样适用。
There came the engineer.
There happened to be a friend of mine in the park.
There once lived an old fisherman in a village by the sea.

3.直接引语的全部或一部分放在句首时，引述动词和它的主语有时装。
“May I come in and take a rest?” asked the pool girl.
“Get out of the room!” shouted the angry woman.

4.以here, there, now, in ,out, up, down, away, then等副词开头的句子中，句子要倒装，以示强调。习惯上，除以then开头的句子用过去时外，其余一般使用现在时。

There goes the bell.铃声响了。
There comes the bus! 汽车来了。
Out rushed the children.孩子们冲出来了。
Now comes your turn.现在轮到你了。
Then came a new difficulty.接着有个新难题。
注意：在这种句型中，如果主语是代词时就不倒装。
Here you are.
There he comes.

5. 虚拟条件句的省略与倒装
当if引导的虚拟条件从句中含有had, were, should等时，如将if省略，则要将had, were, should等移到主语前，构成倒装句：
Had you come yesterday, you would have seen him.
若你昨天来，你就会见到他了。
Should you require anything give me a ring.
如果需要什么，可以给我打电话。
Were it not for your help, I would still be homeless.
要不是你帮助，我会仍然无家可归。
注意：省略if后提前的had不一定是助动词：
Had I money, I would buy it. 假若我有钱，我就会买它。
