what、in which、which和that在应用上的区别
It was in that small room______they workde hard and dreamed of better days to come.句中,四个选项,答案选“that”.为什么?这四个词在应用上分别用在什么句式上,请举例说明一下!

这是一个强调句型,原句是They worked hard and dreamed of better days to come in that small room.
而强调句型的结构就是It is/was +被强调的部分 + that + 剩余的部分.其中,连接词只能用that且不可省去.
至于其他的那三个连接词,不是一两句能说清楚的,LZ得自己查阅了…
