我要的不单单是答案，请祥细解释一下。事关下个星期的考试能否通过。谢谢～～～

1、D 没找到合适的工作是在他放弃在这个城市找工作之前发生的，是过去的过去，所以用完成时，又是句首用having。

2、A 这个提议被接受的话，我们就要做另外一个有关何时开始这个工程的决定。提议是 被接受

3、D Tom 不可能参加了那个聚会，因为昨晚没人在那看见他。对过去事实的否定回答，用过去完成时。

4 、not to speak tell sb not to do sth

1 A 根据主句谓语动词可判断，在句中作原因状语丛句

2 A “见意“是被接受，选项中能够表示此意的只有A D，而be原形不能直接作谓语，所以排除D

3 由句意可知：说的是汤姆“不可能”参加了晚会，而且是过去的事，所以选D

4 固定结构tell sb not to do sth ，故为not to speak

祝你考试顺利通过！
