答案及解析：

1. A 考查情态动词的本义，征求对方的意见

2. C 考查情态动词的本义，表示通常的能力，couldn't是最大的干扰项，学生会受前面were所表示虚拟语气句型的影响。

3. B 考查情态动词would rather句型，宾语从句中用过去时，反意问句助动词应与从句中的went保持一致。

4. C 该句的they ____ put forward是定语从句，表明过去的事实：“他们提出的要求”因此不用情态动词。

5. B 考查情态动词的本义，征求对方的意见，must表示“必须”。

6. B 考查情态动词的虚拟用法。还原成原来的句型是：If you should be fired---，该句型中用should或were to be表示与将来的事实相反。例如：_____it rain tomorrow, the meeting would be put off.

A. Should B. Would C. Could D. Must 分析：在条件状语从句中，should表示“万一”，即可表示不能实现的假设，又可表示可以实现的假设。该句意思为“万一明天下雨，会议就延期。”答案为A。该句等于If it should rain tomorrow, the meeting would be put off.= If it were to rain tomorrow, the meeting would be put off. = Should it rain tomorrow, the meeting would be put off.= Were it to rain tomorrow, the meeting would be put off.
