上海牛津版高一上册英语情态动词专项讲解与巩固拓展练习(有答案)
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？ Can the story be true? 这个故事会是真的吗？

高中英语情态动词精讲与解析
高中英语情态动词精讲与解析 概说 助动词(auxiliary)主要有两类：基本助动词(primary auxiliary)和情态助动词(modal auxiliary)。基本助动词有三个：do, have和be；情态助动词有十三个：may, might; can, could; will, would; shall, should; must, need, dare, used to, ought to. 上述两类助动词的共同特征是，在协助主动词构成限定动词词组时，具有作用词的功能： 1）构成否定式： He didn't go and neither did she. The meeting might not start until 5 o'clock. 2）构成疑问式或附加疑问式： Must you leave right now? You have been learning French for 5 years, haven't you? 3）构成修辞倒装： Nowhere can he obtain any information about his sister. Hardly had he arrived when she started complaining. 4）代替限定动词词组： A: Who can solve this crossword puzzle? B: Tom can. A: Shall I write to him? B: Yes, do. 情态助动词的特征 基本助动词与情态助动词最主要的区别之一是，基本助动词本身没有词义，而情态助动词则有自己的词义，能表示说话人对有关动作或状态的看法，或表示主观设想： What have you been doing since? （构成完成进行体，本身无词义） I am afraid I must be going. （一定要） You may have read some account of the matter. （或许已经） 除此之外，情态助动词还有如下词法和句法特征： 1）除ought和used以外，其他情态动词后面只能接不带to的不定式。如果我们把ought
