题目内容
13.-Who is that man?-That _______ be Mr.Green.He always walks this way.Hi,Mr.Green.( )
| A. | can | B. | may | C. | must | D. | need |
分析 --那个人是谁?
--那一定是Green先生.他总是这样走路.嗨,Green先生.
解答 答案:C.can可能,may可能,can和may在表示可能性上,can的语气比may要强烈,may要显得婉转.而且can多用于口语,在正式用于中多用may,在陈述句中,can的可能是指逻辑上的可能性,may的可能是指事实上的可能性.must一定,必须;need需要.根据He always walks this way.Hi,Mr.Green,可知他经常这样走路,并且他都在跟那人打招呼了,说明说话人已经很肯定那人就是Green先生,所以用语气最肯定的must.故选C.
点评 本题考查了情态动词的用法.解答时注意区分辨别句意以及所给选项的意思并作出正确选择.
