The repairs cost a lot, but it’s money well spent.
这个句子中it指什么。
这个句子是不还可以改成The repairs cost a lot that/which was well spent。
那it是不指a lot of money。
其实a lot 可以看成代词么。
-------------------------------------------------
那这个句子是非限制性定语从句吗。没有关系词啊。
it指代cost，修车的价格。不能用that引导这样的定语从句，因为that在定语从句中不能作主语，which可以做主语，可以引导。但是要用which应该说：The repairs which cost a lot was well spent.或是：The repairs which was well spent cost a lot.总之，which是关系代词，它所修饰的先行词是the repairs....
