5、t, have to, shall/should, will /would ,need, dare, be able to等。情态动词在句子中有多层次意义。1. Can（1）能够，会（表体力和智力方面具有的能力，可与 be able to互换），女口：Can you draw horses?（智力方面）你会画马吗？We can go skating.（体力方面）我们会滑冰。（2）可能（表客观的可能性或推测，通常用于否定句，肯定（不）的意思）,女口：You can't be wrong .（可能性）你一定没错。（3）表示非正式的请求或许可，此时可与may互换，但may更为正式。女口：Ca

6、n/May I borrow your book?我可以借一下你的书吗 ？（4）could是can的过去式，但当 could出现在句首引导问句时，通常不做过去式，而表达委婉的请求 或建议。女口：Could you give me some bread?请你给我些面包好吗 ？2.

8、have to。 如：We must keep our classroom clean .我们必须保持教室干净。You mustn't smoke here .你不可以在这吸烟。Must I go to school today?Yes , you must. / No, you needn't.今天我必须去上学吗？是的，你必须去。/不，你不必去。（2）have to指在客观条件下，迫使主语不得不”做某事，它有人称、数及时态的变化，在情态动词中有点特别。女口：I have to do my homework first .我不得不先完成家庭作业（虽然不情愿）oDo you ha

9、ve to stay at home? Yes , I do . / No , I don't.你不得不待在家里吗？是的，我必须。/不，我不用。（3）表推测时，must意为育定，一定”，表说话人对事物的肯定推测，有百分之百的把握。女口：He must be at work .他肯定在上班（非常有把握）。4. shall 和 will（1）shall 一般用于第一人称，用于征求意见，提出建议。will表示意愿，决心”，可用于任何人称。如：Shall we go to the Zoo?我们去动物园，好吗 ？I will try my best to help you .我将尽力帮助你。sh

10、ould是shall的过去式，但should也可用原形，表示 应当，应该”，此时可与oughtto互换。女口：We should hand in our homework on time .我们应该按时交作业。5. need 禾口 dareneed表需要"，dare表敢于"，都是双栖词"。它们既可做情态动词，也可做行为动词。用做情态动 词时，它们只能用于疑问句，否定句或条件状语从句中；在肯定句中只能用做实义动词，后接名词，用 动词不定式（主动含义）或动词现在分词的形式（被动含义）oMy bike needs repairing .我的自行车需要修理了 （被动含义）
