关系代词在定语从句中省略与介词提前加关代？

Question

我写了2个句子，并改写了很多种表达方式，不知道对不对

Answer 1

回答如下：
在定语从句中，若关系代词在定语从句中作宾语，关系代词可以省略; 若关系代词在定语从句中作介词宾语，介词可以提前，即置于关系代词之前。例如：
1. This is the house (which / that) you want to buy.
2. He is the man (who / whom) you talked about.
= He is the man about whom you talked.
3. The house (which / that) you live in is really beautiful.
= The house in which / that you live is really beautiful.
需要指出的是，介词提前后，关系代词不能用who 或者that。

Answer 2

关系代词在定语从句中作介系词或动词的宾语，在限制性定语从句中，这时关系代词可以省略，但如果把介系词放在关系代词的前面，关系代词就不能省略了，指人只能用whom，指物只能用which，而不能用关系代词that和who。本回答被网友采纳
