then倒装

完全倒装
1) 完全倒装即把整个谓语放到主语之前（是整个谓语动词,而非助动词）.
例如：In came the students and the class began. 
例如：There appeared to be a mouse in the far corner . 
例如：Under that tree sits a charming lady.
本句倒装的条件是：当表示方位的副词或介词短语放在 句首时,要完全倒装.
如：Out ran the boy.=The boy ran out.
如：In came the police=The police came in.
如：Down poured the heavy rain=The heavy rain poured down.

2.部分倒装
1) 部分倒装即只把谓语的一部分（如助动词、情态动词等）放到主语前,或把句子的强调成分提前.
例：Would she leave right now,she would get there on Sunday. 


Then 的完全倒装和部分倒装：


Then 的完全倒装：
The chairman came then=>Then came the chairman.
Computer was used in teaching then =>Then computer was used in teaching


Then 的部分倒装的基本没有,因为部分倒装一般的规律是状语或者否定词或短语开头
我只想到用now and then 和 by then:
例：I can see some people walked by now and then => Now and then I can see some people walked by.
例：I am sure that you will start to love me by then.=>By then I am sure that you will start to love me ! 



清楚了吗?
