情态动词讲解及练习(含答案)一、单项选择情态动词1．—You rang me up at about 10:00 last night, didn't you?—No, I didn't phone you. It someone else.A．must have been B．could be C．must be D．could have been 【答案】A【解析】【详解】考查情态动词+have done。
句意：“昨晚10点左右你给我打了电话，是吗？”“不，我没给你打电话。
一定是别人干的。
” must have done 是对过去发生的动作最有把握的猜测，意思是“一定”，结合语境可知，我没有打电话给你，因此猜测一定有别人给你打了电话。
故选A 项。
2．—I don’t really like Janes. Why did you invite him?—Don’t worry. He come. He said he was’t certain what his plans were.A．must not B．need not C．would not D．might not【答案】D【解析】考察情态动词，题干中的he wasn’t certain说明他可能不来，可能来，因此使用不完全否定，might not。
3．Mr. Baker, some students want to see you. ______ they wait here or outside?A．May B．Should C．Shall D．Will【答案】C【解析】【详解】考查Shall的用法。
句意：贝克先生，有些学生想见你。
他们是在这里等还是在外面等?Shall用于第一、第三人称疑问句中，表示说话人征求对方的意见或向对方请示。
故选C。
【点睛】Shall的用法Shall作为助动词，一般用于第一人称Ⅰ和We，表示一个将来的动作，构成将来时态。
