题目

i love to go to a place that/which has lots of wonderful sights.先行词为什么要用that/which
1.i love to go to a place that/which has lots of wonderful sights.为什么这个定语从句的先行词用that/which,在句充当什么成分.place 不是地点吗,能不能用where.
2,I love places where the people are really freindly.为什么这句又可以用where.

答案

1.因为这里的that在后面的从句中是做主语的,（谓语是has...）因此不能用where,where只能做状语
I love to go to a place.The place has lots of wonderful sights.这两个句子合起来就是你的原句.
2.这里where是从句的状语,因此不能换成重点that
I love places.The people there are really friendly.原句是这两个句子合在一起得到的.
