Answer 1

求答案解释
1.The man insisted that he____there.
D be sent ==should be sent ------insist that +句子（谓语动词是should+一般式动词，should可以省略）

2. If it ___A___rain ,we ______ get wet.(我选了B,为什么错）
虚拟语气排除were going to 这个结构，用were to 替换就对了

3. I would have come earlier ,but I _____that you were waiting for me .(我选B 错了，求理由）
A didn' t know -------这是“当时”的实际情况，所以用一般过去式

4. He insisted that he __had seen___me before,------强调“说”----该什么时态就用什么时态。
5.He insisted that John __do ___ it ------这里强调一种“要求，意愿”。

6. It is high time we ___B____ off (这句话什么意思）------我们真正地应该离开了，（但是还没有离开）-----表示说话人不耐烦了。
B

7. I would have told him the answer had it been possible but I __c___so busy then
C was -----指的是“当时”的事实情况，不是虚拟语气

8. Tom would buy that bicycle but he ___has__ no money (为啥选B 不选A 呢）
would buy----指的是现在或者将来“买不起”，所以用has----说明他“现在”没有money
