为什么用which?places不是复数吗

Answer 1

首先要明确,这个句子是一个定语从句,可以把句子成分分开来看,可能你会更明白一些：
There are many places of interest [which attract millions tourists( from all over the world.)]
句子的主干是：There are many places of interest.其中的用“[]”括到的部分是做的“places of interest” 的后置定语,用来修饰“places of interest”的,也就是说,places做的先行词,which做的引导词.句子意思是：“这里有很多每年吸引来自世界各地上百万游客的风景名胜.”就是这个意思.
