问题描述：
this is the third week ___ the dustmen haven't come for the rubbish?
A.that B.when C.which D.on which
A 为什么不用B 这是什么固定句型吗
答
一般说来,在It[This] is the first time＋ that 结构中,that 从句通常用现在完成时：
It's the first time（that） the boy has spoken to a foreigner．
这个男孩还是第一次同外国人说话.
It's the first time that she's seen an elephant．
这是她第一次见到大象.
有时以上结构中的first 也可换成second,third,fourth 等；其中的time 也可换成其它名词：
It's the first month that he has lived here．这是他第一个月住在这里.
This is the second cigarette that he has smoked today．这是他今天抽的第二支烟.
