1.A couple of days had passed by_______ l realized the camera was missing.
A as B before C since Dwhen
我选了A 但答案是B why?
A和D这里表示当什么的时候,SINCE 表示从什么时候开始,都是一个伴随的过程,相机丢了是一个点的动作.所以是B.
2.Jackie _______for he went hunting yesterday without being permitted .
has been punished B.punished C.was punished D.would punish
我选了A 答案是C A的确不对 可是C也不太对..
这个个被动句,Jackie 被惩罚,（be + 过去式）FOR 后面表示原因.
3.As she _______,Catherine burst out laughing.
deeply moved B.has deeply moved C.was deeply moved D.was deeply moving
为什么D不对..答案是C
AS这里表示因为,不要和第一题中的AS混淆,
一样是被动句,因为她被移动,所以是BE+过去式.
4.The police found (that) the building _______and that a lot of personal belongings_____
A had been brokeninto:into
B.was broken into:had been stolen
C.had broken into:had been stolen
D.has broken into:has been stolen
正确答案是A
后面一个空一定是被动语态的 东西被偷掉.怎么会是A
这个我也觉得不应该是A,可能是答案印错掉了,
