Question

麻烦讲一下as在这几个句子的从句里做什么成分
You can wait for me at the same place as we did.
He is no longer the same boy as he used to be.
He is such a clever boy as every teacher likes.
I have never seen so clever a boy as he (is).

Answer 1

You can wait for me at the same place as we did.
as是引导词,引导定语从句
He is no longer the same boy as he used to be.
as是引导词,引导定语从句,as代表boy,he used to be boy
as作表语
He is such a clever boy as every teacher likes
as是引导词,引导定语从句,as代表boy,teacher likes boy
与前面such搭配,such...as,as作宾语
I have never seen so clever a boy as he (is)
如果is省略的话,as就是介词,
is 不省的话,as还是定语从句
as都是一个意思“如...,像.”
