People _ wear warm clothes.A. must B. have to C. can D. should答案点拨1. 答案选A。用must开头的疑问句，其否定回答英语习惯上要用neednt；由此可排除B、C和D。2. 答案选C。根据后文中的It has her name on it（上面有她的名字）可知，这个笔记本“一定”(must)是Jane的。3. 答案选A。根据前文中的Im not sure（我不太清楚）可知，其后应填一个表示把握性不太的推测，即填may（可能，也许）。4. 答案选A。根据句中的She has gone to Beijing（她到北京去了）可知，那个人“不可能”是Helen，即选cant。5. 答案选C。前文说Anna没来上学，但只是她生病的一种可能，并不能肯定，所以空格处应填may（也许）。6. 答案选C。问句中的May I表示请求允许，而答句以no开头，说明答话者拒绝了对方的请求，故空格处应填mustnt（不准，不允许）。7. 答案选C。May I（我可以吗）用于表示请求。又如：May I use your telephone? 我可以用你的电话吗?8. 答案选B。根据后文的This is a non-smoking area（这是无烟区）可知，此处不准吸烟，故选B。9. 答案选B。根据句中的I saw him go to the library just now（我刚才在图书馆看到他了）可知，在游泳池里游泳的人“不可能”是Mr Smith，即选cant。10. 答案选A。should 的意思“应该”，should not的意思是“不应该”。全句意为：不满16岁的孩子不应该在街上开车。11. 答案选A。对于以must开头的一般疑问句，其肯定回答用must，否定回答用neednt。12. 答案选B。根据上面一题的说明可知，此题是对以must开头的一般疑问句作否定回答，故用neednt。13. 答案选B。may在此表示推测，意为“可能”，句意为：如果不够仔细，老师也可能会出错。14. 答案选C。根据I have to take a piano lesson at 2 pm（我下午两点钟要上钢琴课）可知，说话者“不能”去，故填cant。15. 答案选B。根据空格前的Yes（会）和空格后的its easy（那很容易）可知，空格处应填can，表示现在的能力，意为“能，会”。16. 答案选D。根据句中的for your study and your health（为你的学习和健康）可知，空格处应填语气较强的must（必须）。对话的意思是：“我真的喜欢玩电脑游戏！”“为了你的学习和身体恐怕你必须停止。”17. 答案选D。could可以是can的过去式，表示过去的能力。但在此题中它不表示过去，而是表示一种委婉语气，即请求别人允许自己做某事，其回答一般用can，而不用could。18. 表示请求别人允许自己做某事常用may，意为“可以”。如果答语是表示允许，可用may来回答；如果答语是否定的，则用mustnt或cant 来回答。答案选C。19. 根据常识可知，学校应该允许学生一天至少有一小时的时间来进行体育活动。在所给的四个选项中，只有should符合题意，其意为“应该，应当”。20. 根据前文中的Its too cold here in winter（这儿冬天太冷了）可知，外界条件迫使这儿的人们“不得不”要穿暖和的衣服。这里所强调的是客观，而不是主观，故答案选B。
