after做介词和连词用法

Only after what seemed a long time did rescue come to him . 如果after为介词,what在宾语从句中做主语,但如果把after理解为连词,后面应该接句子,用it作主语,指时间不也说得通么,原句可还原为Rescue came to him only after it seemed a long time .刘老师能告诉我it为什么不行

after what seemed a long time (正)

结构正确,语义也正确。after 是介词,后接包括名词性从句在内的名词或名词词组。

1. 因为what 是融合性关系代词,所以:after what seemed a long time 约等于: after a long time又如:He lives in what seems like a hut. 约等于:He lives in a hut.

2. after 用作介词时,可以接:时间点;时间段。

after three o'clock:在三点之后

after three hours:过了三个小时之后

例如:

The meeting began after three o'clock, and after three hours, it was over.

会议在三点后开始,过了三个小时后,会议结束了。

 

然而,用作连词, after 只表示在一个动作结束之后,例如:After the guests left, they went to bed.

但没有第二种用法(即:没有“经过了多长时间之后”)。说明下句是错误的。至少是逻辑错误:

after it seemed a long time (误)

这里after 用作连词。结构正确,但语义错误。after it seemed a long time 跟以下句子结构上没有区别,简直不敢想象它们是什么意思:

After this was a book, ...

After she was a girl, ...

After it was a long way...

After it was Sunday...
