6. 　　　fired, your health care and other benefits will not be immediately cut off.( 湖北卷)

A. Would you be　　 　B. Should you be　　 C. Could you be　　　 D. Might you be

解析：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.

3. I’m sure you’d rather she went to school by bus, _______? (福建) 　　　　 A. hadn’t you　　 B. wouldn’t you　　 C. aren’t　　　 D. didn’t she

解析：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。

2. If it were not for the fact that she ____sing, I would invite her to the party. (福建)

A. couldn’t　　　　 B. shouldn’t　　 　C. can’t　　　　 D. might not

解析：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。
