情态动词的特殊用法
情态动词的特殊用法是历年高考的考查热点。下面我们以实例进行解析，帮助同学们更好地掌握该内容。
1. _____ fired, your health care and other benefits will not be immediately cut off.
A. Would you be B. Should you be
C. Could you be D. Might you be
解析：答案为B。Should you be fired = If you should be fired。英语中should是一个常用的情态动词，但它可用于条件状语从句中，表示语气较强的假设，意为“万一，竟然”。
2. —What’s the name?
—Khulaifi. _____ I spell that for you?
A. Shall B. Would C. Can D. Might
解析：答案为A。Shall I/we . . . ? 是用来表示征求对方意见或建议的常用句型，它不表示将来。注意：shall的这一用法也适用于第三人称的疑问句中。例如：Shall he come to see you?（要不要他来看你?）
3. John, look at the time. _____ you play the piano at such a late hour?
A. Must B. Can C. May D. Need
解析：答案为A。此题考查must的特殊用法。这里must表示与说话人相反的愿望或语气不耐烦，意为“偏偏，偏要”。注意：近几年must表示“偏偏，偏要”这一用法已成为高考的一个热点。
4. —Must I turn off the gas after cooking?
—Of course. You can never be _____ careful with that.
A. enough B. too C. so D. very

5. Some aspects of a pilot’s job _____ be boring, and pilots often _____ work at inconvenient hours.
A. can；have to B. may；can
C. have to；may D. ought to；must
解析：答案为A。考查can表示一时的可能性、偶尔发生的事情，意为“有时会”。这个考点在近几年高考中备受青睐。第二空表示“不得不”。
6. —When can I come for the photos? I need them tomorrow afternoon.
—They _____ be ready by 12:00.
A. can B. should C. might D. need
解析：答案为B。should可用于肯定句中，表示说话人较为婉转的推测，并留有余地，具有“可能；该”之意。
7. When he was there, he _____ go to that coffee shop at the corner after work every day.
A. would B. should C. had better D. might
解析：答案为A。would此处表示过去反复发生的动作或行为，意为“总是，习惯于”。

—You _____ have my computer if you don’t take care of it.
A. shan’t B. might not
C. needn’t D. shouldn’t

9. You can’t imagine that a well-behaved gentleman _____ be so rude to a lady.
A. might B. need C. should D. would

12. The fire spread through the hotel quickly but everyone _____ get out.
A. had to B. would
