Mark was a student at this university from 1990 to 1995,during which time he studied hard.为什么during后面用which?
After the war,a new school building was put up where there had once been a theatre.这里 where there had once been a theatre.there有什么作用,去掉可不可以?此句可不可以改为这样After the war,a new school building was put up there where had once been a theatre.

which指代1990 to 1995,during介词后用名词
解释学校建成的地方是哪 是原先的剧院
不可以
不可以

这里的which是代替上文的from 1990 to 1995的一个定语从句,引导词为which。这里的where也是一个定语从句的引导词,在定语从句中做主语要放在定语从句的开头。你可以多看看有关此类的定语从句。这是我的看法,我不能保证全对!

He studied hard during the time (from 1990 to 1995).
在从句里面,1990 to 1995是做during的宾语啊
当然用which
这个there是there be句型(这个是过去完成时的There be),当然不能去掉
不可以变成你这样
