as不能当先行词
as作为关系代词,代替整个句子,在定语从句中做主语和宾语,意思为,“正如...”.它引导的句子既可以在主句前、后,也可以放在句中,
1.as做主语
请分析下面两个简单句:
句① America is a developed country.
句②It is known to all.
把句②变为句①的定语从句,句①做定语从句的先行词.在句②中it指句①中提到的China is a
developing
country.也就是定语从句的先行词,it在句子中做主语,因此要用as引导定语从句,代替句②中的it,也就是说it就不能出现在定语从句中了.由此得到句③As
is known to all,America is a developed country.
2.as做宾语
请分析下面两个句子:
句①We won the game.
句②We all expected it.(that we would win the
game).
把句②变为句①的定语从句,句①做定语从句的先行词.在句②中it指句①中提到的.We won the
game就是定语从句的先行词,it在句子中做宾语,因此要用as引导定语从句,代替句②中的it,这时it就不能出现在定语从句中了.由此得到句③We won the
game,as we expected.
