情态动词 一、概述 情态动词表示说话人对某一动作或状态的态度,认为“可能、应当、必要”等等,但本身意义不完全,不能单独作谓语,必须和其他动词一起构成谓语。除ought, used, have后跟不定式外,其他情态动词一律跟动词原形。情态动词主要有:can/could, may/might, must, ought to, used to, need, dare, shall/should, will/would, have to等。 二、基本用法 (一)can和could的用法 1.表示能力,可译为“能,会”。 I can swim. 我会游泳。 Emily can dance well and her mother could dance well when she was young. The cinema can seat 1,000 people. I could not read such an easy book when I was 7 years old. 2.表示允许、许可,常用在口语中。could比can语气上要客气。 --- Could I use your dictionary? 我可以用一下你的字典吗? ---Yes, go ahead. 可以,用吧。(或Yes, you can. 但不能说Yes, you could.) Could/ Can you tell me how to get to the zoo? 劳驾,你能告诉我怎么去动物园吗? He asked me whether he could take the book out of the reading room. 3. 表示可能(理论上或是逻辑判断上)。 The temperature can fall to–60℃,that is60℃below freezing.气温可降至—60℃,也就是零下60℃。 You mustn′t smoke while you′re walking around in the wood.You could start a fire. 在林子里走时勿吸烟,那样可能会引起火灾。 3.表示推测,可用于肯定句(can罕见)、否定句和疑问句,但更常见于疑问句或否定句。在此种用法中can和could没有时态的区别,只是表示可能性的大小,can表示推测的可能性比could大。 Can he be ill at home? 他会是生病在家吗?
