Unit 9 (1)
重 点 初中常见情态动词用法（一） can 的用法 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。 表示可能、能够。 如：I can finish it in an hour. 我能在一小时后完成它。 表示许可，常在口语中。如：You can use my dictionary. 你可以用我的字典。 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 ----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。 例 --- I think Miss Gao must be in the library. She said she would go there. ----- No. She __ be there, I have just been there.A.can’t B.mustn’t C.needn’t D.wouldn’t根据下文“我刚去过那儿”可知，应为“ 不可能”， can’t 表示推测 A 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 a favour 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。 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----_______ 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”。答案 A 表示推测，谈论可能性，意为“ 可能， 或许”，一般用于肯定句中。 如：It may rain tomorrow . 明天可能会下雨。 She may be at home. 她可能在家呢. (3) may的过去式为might ，表示推测时。可能性低于may 。 如：He is away from school. He might be sick.他离开学校了， 可能是他生病了。
难点 --Can you come to my party 你能来我的聚会吗？
--Sure, I'd love to. 当然，我很愿意。（掌握肯定回答，这点经常考）
2. --Can you go to the movies 你能去看电影吗？
--I'm sorry.I have to help my mom. 对不起，我必须帮我妈妈。（先拒绝，再说明理由）
3. --Can she go to the baseball game 她能去棒球赛吗？
--No, she can't.She has to study for a test. 不能，她不得不为考试学习。 【句型应用】如何对别人的邀请说愿意或表示拒绝，并学会如何讲清原因。
如：当同学邀请你去看电影时，你非常愿意。那么你就应该说：
Sure! I'd love to. 或说：Sure! I'd like to.（重点）
注意在这两种中“to”不能省掉，否则意思不完整。
如果我们有事不能去，我们可以说：
Thank you very much for your invitation. 非常感谢你的邀请，但很抱歉我不能去。
或说：Thanks for asking. I'm sorry, I can't. 谢谢你的邀请，但是我不能去。（注意asking的形式）
接下来我们应该陈述理由。如：我必须帮助我的妈妈。 I have to help my mom.

U9（4）
重 点 初中常见情态动词用法（四） 易混点一 : can 和 be able to 两者表示能力时用法相同， 但 can 只有原形 “can” 和过去式“ could ”两种形式，在其他时态中 要用be able to 来表示。 另外 be able to 常常指经过努力， 花费了时间和劳力之后才能做到某事。如： Jim can’t speak English. 吉姆不会说英语。 He could speak English at 5. 他五岁时 就会说英语。 We’ll be able to see him next week.下星期我们将会见到他。 易混点二 :can和may 1. can 和 may 均可用来征求意见或许可，意为“可以”， 一般可互换使用。如： Can/ May I help you 我能帮助你吗？ 2. can 和may 表示可能性时的区别： 1) 在肯定句中用 might， may， must， 不用can 2) 在疑问句中表示推测用 can，不用 might， may，must 3) 在否定句中用can’t（不可能）， 不用 may， must。 如： She may be in the classroom . 她可能在教室里。 That can’t be true. 那不可能是真的。 易混点三: may be 和maybe may be may为情态动词，be为动词原形 句中，作谓语 maybe 副词，大概、也许，相当于perhaps 句首，作状语 He may be wrong , but I’m not sure. 也许他错了，但我也不确定。 Maybe he is wrong, but I’m not sure . 易混点四 : can’t 和 mustn’t 1. can’t 根据其基本用法可译为： （1） 不会， 如：I can’t speak English . 我不会说英语。 （2） 不能， 如：We can’t do it now because it’s too dark. 天太黑了， 我们现在干不了。 （3） 不可能， 如：那个人不可能是咱们老师， 他年轻得多。 2. mustn’t 意为“ 禁止、不许”， 用来表达命令，表示强烈的语气。 如： You mustn’t play football in the street. It’s too dangerous.你不可以在街上踢足球， 太危险了。 易混点五 : must 和 have to 1. must 侧重于个人意志和主观上的必要， 还可以在间接引语中表示过去的必要或业务。 2. have to 侧重于客观上的必要，可用于现在时、过去时和将来时。如： I know I must study hard.我知道我必须努力学习。 My brother was very ill, so I had to call the doctor in the mid-night. 我弟弟病得厉害， 我只得半夜里把医生请来。 I haven’t got any money with me, so I’ll have to borrow some from my friend. 我身上没带钱，只好向朋友借点了。 He said they must work hard. 他说他们必须努力工作。
难点 Please reply in writing to this invitation by Friday,December 20th.请于12月20日星期五前以书面方式回复此邀请。 【解析】1）reply in writing表示“以书面的形式进行回复”。其中reply相当于answer，但要比后者更加书面化且正式许多。此处介词in表示方式，相当于汉语“用......方式（形式）”的意思。 2）reply用作动词时，不直接跟宾语，须由介词to引入宾语的内容，构成reply to...结构。例如：Did you reply to these letters 你回复这些来信了吗？
