(答案→)A. can
B. should
C. may
D. must
解析:考查情态动词表达推测。can通常用于否定或疑问句中表示推测,表示可能性。这句话的意思是“布什先生一直按时做好所有的事,他怎么可能开幕式迟到呢?”。用于否定句表示“不可能”,此时要与may not“可能不”的含义注意区分,如:
She may not tell lies. 她可能没撒谎。
He can’t have been to your home. He doesn’t know your address. 他不可能去过你家,他都不知道你们家的地址。
can用在肯定句中也有表示推测的意义,但表示理论上存在的可能性,翻译成“有时可能”(但很少发生),如:Even experienced teachers can make mistakes.
