题型:不详难度:来源:
The weather in the south is generally warm, but it________ be very cold sometimes.
A.mayB.shall C.willD.can

答案
D
解析

试题分析:句意,南方的天气通常很暖和,但有时也可能很冷。May表示可能性比can小;shall表示征求对方意见;will表示意愿;can表示推测,根据比较,故选D。
点评:用情态动词表示可能性的层次,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。
