定语从句里面可以再套一个定语从句吗

当然可以的。
如：Many people who had seen the film were afraid to go to the forest that looks like the one in the film.
第一个从句：who had seen the film修饰前面的people, 第二个：that looks like the one in the film修饰the forest.

在英语定语从句中从句时态是和主句一样吗
定语从句的谓语动词不必和主句的谓语动词在时态上有什么一致的问题,根据每句中发生的动作或存在的状态的时间而定,比如：
I visited the house Chairman Mao had lived in.
The man I spoke to is my uncle.
The boy who is brave passed the examination.
I know the the man he was talking to just now.
而宾语从句中的谓语动词要和主句的谓语动词在时态上保持一致.

定语从句的关系代词 that的用法:若先行词指人或物则代替先行词在定语从句中充当主语或宾语

先行词 指物代替先行词在定语从句中充当主语
She is the person that \who we are worried about.
先行词 指人代替先行词在定语从句中充当宾语
