such ...as 与 such as 有什么不同?两个as 的词性是?
答
such as中的as一般只视为介词,类似于like的用法,其后加名词性成分,表示不完全例举.
如：I have many friends, such as Tom, Lucy and Mike.
such...as...中的as一般有两种用法.
1）as做介词（此时 such...as... = such as...）
如：I want to be such a scientist as Yuan Longping.
我想成为袁隆平那样的科学家.
2）as做连词（引导从句）
如：I don't like such books as he recommended.
我不喜欢他推荐的那些书.
