一、预习P61-62，在课本中划出这些短语并翻译：
1. go towards the water________________ 2. go near the lions and tigers________________ 3. jump around______________________ 4. stand with its eyes closed_________________ 5. for example_______________________ 6. work out easy maths problems_____________ 7. with the help of_____________________ 8. get lost ___________ = _______________ 二、知识延伸： 1. may的用法： (1)表示请求允许：可以
eg. ---- May / Might / Can I come in? 我可以进来吗？ ---- Yes, please. （might不是过去式，只是更婉转。）
He said I might borrow his car.他说我可以借他的车。（might为may的过去式。） (2)表示给予允许：可以 （不能用might）
eg. You may bring it back tomorrow. You may not go there. (3)表示推测，解释为“可能”。
eg. 他现在可能很忙。 He may be very busy now. 我今天可能会晚点回家。I may go home a little later. 他们明天可能不上学。They may not go to school tomorrow. 2. may / may be / maybe
may + do 可能做某事 may be + adj. 可能是（某种状态） maybe adv. 可能= perhaps eg. 她可能今天下午来。Maybe she will come this afternoon. / She may come this afternoon. 你可能是对的。 Maybe you are right. / You may be right. 三、小练一把：
1. ---- Might I …? ---- Yes, you ________. / No, you ________. 或 No, you _________. 2. ---- May I …? ---- Yes, you ______. / No, you ______. 或 No, you ______. 3. ---- Must I …? ---- Yes, you ______. / No, you _______. 或 No, you _______. 4. ---- Need I …? ---- Yes, you ______. / No, you ________. 5. ---- Can I …? ---- Yes, you can. / No, you _______. 【课堂学习】
