我们在英语学习中会经常遇到顺序倒装的句子，例如：
Here came the headmaster. 正常语序应该是，
The headmaster came here.
用倒装句子就语气更强，场面描写会更生动。一般倒装句有这样的7种形式。
一、There be句型
There is a book on the desk. 正常语序是，
A book is there on the desk.
There lives an old man by the sea.
An old man lives there by the sea.
二、here、there、now、then等开头的句子
Here comes the bus!
Now comes your turn.
但是注意，如果主语是人称代词，则不倒装，如：
Here you are.
There she comes.
三、当表示地点的介词词组在句首
At the foot of the hill lies a beautiful lake.
Under the tree was lying a cat.
四、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 clever child.
Not until the baby fell asleep did the mother leave the room.
五、so, neither, nor在句首
He has been to Beijing.
So have I.
Tom can’t answer the question.
Neither /Nor can I.
六、only在句首
Only in this way, can you learn English well.
七、在引用语后
“ Let’ go,” said the man.
主语是代词时, 一般不用倒装结构。
“ Let’s go,” he said.
