题目内容
3.---You are sweating.______ I fetch you some water?---It's so kind of you.( )
A. | Can | B. | Must | C. | Shall | D. | Need |
分析 你一直在流汗.要我给你拿些水吗?
你真是太好了.
解答 答案:C.
shall可以用于一三人称,表示说话人征求对方的意见或向对方请示;此处是指看到对方累的在流汗想为他拿些水,所以用shall.根据句意"你一直在流汗.要我给你拿些水吗?"可知选C.
点评 shall除了用于一三人称之外,还可用于二三人称,表示说话人给对方命令、警告、允诺或威胁.can表示能力、请求和允许、客观可能性(客观原因形成的能力)以及推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中.must表示必须、必要,是说话人的主观看法,还可表示推测、可能性(只用于肯定的陈述句).need作情态动词用时,常用于疑问句、否定句.在肯定句中一般用must,have to,ought to,should代替.
