3、g to Alice. 点拨解疑: 语法知识:表示推测的情态动词。 在英语中,表示对某件事物的确定程度,即表示推测的时候,我们通常会用到以下情态动词:must, might, could, may, cant, couldnt. 一. can和could的区别和用法 1.can表示体力和脑力方面的能力,或根据客观条件能做某种动作的能力。 例如: Can you speak English? What can I do for you? can用在否定句和疑问句中时有时表示说话人的猜测或 不肯定。 例如: Where can he be? Can the news be true? (在日常会话
4、中,can可代替may表示允许,may比较正式) 2. could 是 can的过去式,表示过去有过的能力和可能性,还有怀疑和不肯定的意思(在否定和疑问句中)。 例如: She couldnt skate when she was five years old.(能力) At that time we thought the story could be true.(可能性) could用来提问,是有礼貌的请求 Could., please? 语气较为婉转。 例如 Could I speak to Mr. Smith, please? Could you help us carry this
5、box, please? 二. 跟上组词一样, might也是may的过去式,其用法如下: 1. may的用法: a. 表示允许或请求。例May I come in? 在使用这一用法时需注意: may表示允许的否定形式是must not,意思是不应该不许可。 例如:-May I take this book out of the reading-room? -No,you mustnt.不行。 b. 表示说话人的猜测,认为某一事情或许或可能发生。 例如: He may know the answer. Tomorrow I may go shopping. 2. might的用法: a. mi
6、ght可以代替may,表示现在时间的动作,但语气较为婉转客气或更加不肯定。 例如: He might not come today. Might I take a suggestion? b. might用来表示现在时间时,还可表示规劝。 例如: You might pay more attention to spoken English. 三. must与have to的区别 have to比较强调客观需要,must着重说明主观看法。另外have to能用于更多时态,比较下面的句子: We had to be there at ten.我们得在十点钟到那里。 有时两者都可以用,意思差别不大。
7、 must在表示说话人对事物的推测时候要注意它比may肯定得多,相当于汉语的一定或准是。(只有在肯定句中能这样用。) This must be your room. There must be a mistake. 在回答由must引起的问题时,如果是否定 不能用mustnt,而需要用neednt或dont have to,因为mustnt是一定不要的意思。 例如:-Must we hand in our exercises today? -No,you neednt. must not的否定形式则表示不应该或不许可,语气比较强烈。 课堂练习: 一、单项选择1. - Can you swim
