【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 Wall.不可能。
咱们老师正在游览长城呢。
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。
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. Would【解析】在此处表示请求，意为“做……可以吗”。
