解析
试题分析:考察情态动词用法。Can’t不可能;must not千万不能,禁止;won’t不会;may not也许不;句意:—那边的那个是Ann的丈夫吗?—不,不可能是他。我确信他不带眼镜的。Can’t是有把握的否定推测。根据句意说明A正确。 点评:英语中有不少情态动词都可以表示推测,其语气有强有弱,表示的可能性有大有小,现将它们的用法归纳如下:1. 接近100%的可能,只有must才具有这么高的可能性,它的意思是“一定”“肯定”,所作出的推测几乎接近事实。如:He must be coming by bus. 他一定是乘公共汽车来。2. 很有可能,表示可能性较大的情态动词主要有may, should, ought to,它们大致相当于汉语的“可能”“应该”“按理会”。 3. 一般性的可能,在所有表示推测的情态动词中,might和could所表示的可能性最小,由于它们的语气较委婉,较不确定,所以往往相当于汉语的“可能”“也许”“说不定”等。4. 理论上的可能性,表示理论上的可能通常是用can,且可以用于肯定句中。 |
