非限定性定语从句的问题,这个空可以填as吗,为什么?
非限定性定语从句的问题:Have you ever been to Hangzhou,_____is famous for the West Lake?填空可以用as 为什么?可以用as吗?Mr Black is going to Beijing in October,_______is the best season there.
as作为非限制性定语从句的关系代词,它可以指代前面整个句子,但是一般不指代前面的句子中的先行词,如果指代先行词,就要用which.如:
The earth is round,as is known to all.
He was Italian-American,as I knew from his accent.
有时也可以指代某个先行词,但较少用,如:
The two brothers were satisfied with the decision,as had been agreed beforehand.
你给出的这两句句子,因为which指代某一先行词(专有名词),所以不能用as作关系代词.希望我能帮助你解疑释惑.
