我的老师出了一道题问我对或错如下:
You should work on your homework until finished.
老师说整句还原是:you should work on your homework until you are finished.
所以这题是对的,但我有困惑了,You(人) 如何被finish呢?
不是应该要是your homework are finished 吗?
或是我自认为对的还原句和减句如下:
You should work on your homework until you finished
= You should work on your homework until finishing
请问是我的认知有误吗..还是真的如老师所讲finish在子句是特例,要背起来? |
