几个英语问题

Question

1.He said that his car___stolen and he __have to telephone the police
选had been；would 为什么不选was；would
2.Mr,Smith though that___take it back A I shall;tomorrow.B I shall;the next day C he should ;tomorrow D he would the next day 为什么选D
3.Mr Brown is said___a new novel。为什么选 to have written 选to write 表示将来不行？
第二句是因为said才选过去完成时的话，那“I will behave myself”，he promised这句话从句用将来时，主句用过去式是怎么回事？

Answer 1

1、因为car是物品，物品是被偷得。所以用被动语态。
2、应该是thought吧，smith是想，他只能想自己怎么做，而不是我怎么做。而且是过去式，不能用tomorrow，而应该是那天的第二天，所以选D。
3、因为这是过去式。
