5.The police found the house__and a lot of things__.

解答:

1.-Tony__,for he went swimming yesterday without permission.
C was punished
Tony受到了处罚,因为昨天他未经允许去游泳了。
这只是个过去式而已。

2.-All the exercise-books__tomorrow.
A will be collected
明天所有的练习本要收起来。
由于是明天,用将来时。

3.-If rubber__,it gives off a terrible smell.
C is burned
如果点燃橡胶,会发出难闻的味道。
这是个一般规律,用现在时。

4.-World War II __in the 1930's.
A was broken out B had broken out C broke out
D had been broken out
二战爆发在1930年。
发生只是个动作,用过去式就够。

5.The police found the house__and a lot of things__.
B had been broken into; stolen
警察发现房子被人闯入了,并且东西被偷走了。
因为警察的Found是过去式,所以用过去完成时,
Stolen也应该是被动的,前面省略了 had been,语法正确。
