语法规则-情态动词

初中英语情态动词用法详解 【情态动词知识梳理】 情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。 考点一：can，may，must等情态动词在陈述句中的用法： 1. can的用法： （1）.表示能力、许可、可能性。表示能力时一般译为“能、会”，即有种能力，尤其是生来具备的能力，此时may和must均不可代替它。如：She can swim fast, but I can’t . 她能游得很快，但我不能。I can see with my eyes.我用眼睛看。 （2）.表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。（3）.表示推测，意为“可能”，常用于否定句和疑问句中，此时can’t译为“不可能”。如：Can the news be true?这个消息会是真的吗？—Can it be our teacher?那个人有可能是我们老师吗？—No, it can’t be our teacher. He is on a visit to the Great Wal l.不可能。咱们老师正在游览长城呢。 【例题】—I think Miss Gao must be in the library. She said she would go there.—No. She __be there, I have just been there. 【解析】根据下文“我刚去过那儿”可知，应为“不可能”，can’t表示推测[答案] 2. could的用法： （1）.can的过去式，意为“能、会”，表示过去的能力。如：He could write poems when he was 10. 他十岁时就会写诗。 （2）. could在疑问句中，表示委婉的语气，此时could没有过去式的意思。如:Could you do me 你能帮我个忙吗？—Could I use your pen?我能用一下你的钢笔吗?—Yes, you can.可以。（注意回答） 3. may的用法： （1）.表示请求、许可，比can正式，如：May I borrow your bike?我可以借你的自行车吗？You may go home now.现在你可以回家了。 【例题】—_______ I borrow your MP3?—Sure . Here you are. A. May B.Should C.Must D.
