英语 as引导的定语从句
当先行词被such 修饰时用as引导定语从句.即 such...as .那么,such .as 能改成so.as么?
如这个句子
It's such a difficult problem as nobody can work out.
能改成
It's so difficult problem as nobody can work out.
或名词用复数
They are such difficult problems as nobody can work out.
答
引导的原因状语从句：
so+形容词+a/an+名词单数+that从句
=
such+a/an+形容词+名词单数+that从句
答
不能，因为such是形容词，它在这里是修饰名词problem的，而so是副词，要修饰形容词和其他副词
答
1.相关语法规定如下：当先行词被such/so/the same/as修饰时,定语从句的关系代词一般使用as.不过,有时候the same修饰先行词时,定语从句的关系代词也可以使用that.2.所以,such...as改成so...as是可以的,但是必须要注意...
