—I think the man over there must be Bob.—It ______ be him. He has gone to Paris

题型:不详难度:来源:
—I think the man over there must be Bob.
—It ______ be him. He has gone to Paris.
A.can’tB.canC.may notD.mustn’t

答案
A
解析

试题分析:根据 He has gone to Paris.“他去巴黎了。”可知,本句应该是“它不可能是他。”故排除B;“不可能”是can’t。而may not表示“不可以”,mustn’t表示“禁止做”故与题意不符。所以本题选A。
点评:本题实际是考查情态动词表示推测的情况,这很容易与以前学过的情态动词的用法相混淆。情态动词表示推测的情况,表示一般性推测用might、could表示“可能”;表示肯定推测用must表示“一定”;否定推测用can’t表示“不可能”。
