小 结

② Could you come to my party?
③ Would you like to come to my party?
(2) 常见表示接受邀请的回答：

① Sorry. I’m not available. I must....

向别人发出请求、邀请或征求意见其他表达方法:
Would you like to do…?“你想要/愿意……”？
Would you please do…?“请你……好吗？”
Shall we do…?“我们……好吗？”
Let’s do… “让我们……吧。”
Why not do…?=Why don’t you do…? 为什么不…？
How/What about doing…? “……怎么样？”
情态动词 can 有一定的词义，但不能独立存在，它必须与动词原形一起构成谓语。情态动词 can 没有人称和数的变化。其具体用法如下:
表示“能、会”指脑力或体力方面的“能力”。如:
? I can speak Japanese.
我会讲日语。
? Frank can swim but I can’t.
佛兰克会游泳, 但我不会。
情态动词 can 的基本用法
2. 表示“可能”，常用于否定句或疑问句中，指某种可能性。例如：
? My cousin can’t be in this city. He is in Korea now.
我堂兄不可能在这个城市里。他在韩国呢。
? Can he come to our club today, please?
请问他今天能来我们俱乐部吗？
3. 表示“可以”，常用于口语中，指许可或请求做某事
? Can I ask you a question? 我可以问你一个问题吗？
? You can bring something to eat. 你可以带些吃的。
4. can表示请求,用于发出邀请,后跟动词原形。当同意接受
对方的邀请时,常用Sure, I’d love to. / Certainly. /Of course.
等来回答；若不接受,常用Sorry等来有礼貌地拒绝,一般情
况下需要说明不能接受邀请的原因以表示歉意。
? —Can you come to my birthday party tomorrow？
明天你来参加我的生日聚会，好吗？
—Sorry, I can’t. I am going to visit my grandpa.
很抱歉，我来不了，我要去看我爷爷。
Can 表示邀请：
Can you come to my party?
can的用法
情态动词can没有人称和数的变化，过去式为could；其后接动词原形；
否定：can后加not；
疑问：can放主语前。
can表示能力, “能；会”
She can swim, but I can’t.
can表示允许, “能；可以”
You can use my computer.
can表示可能, “能够；会”
I can get there in ten minutes
(1)都可表示“许可”, may用于较正式场合,can比较口语化。
You may/can smoke here.
?You may not take out of the library more than two books at
a time.
?The policeman says you can’t park here.
(2) May/Can I/we…? 表示征询对方许可；Can you…? 表请求。

- No, you may not./No, you mustn’t./No, you’d better not. /
I’m afraid not.//I’m sorry. I’d rather you didn’t.
② - Can I go out and play, Mum?

③ _____多表主观意志._______强调客观需要,意为
_______；在一般现在时中,当主语为第三人称单
数时,变成______.在一般过去时中,变成______.
has to
have to

不得不
must
He doesn’t like the book . He must buy another one.
- He lost the book. He has to buy one.
had to
归纳情态动词can/must/might用法
have to的意思是“必须、不得不”, 往往强调由于客观原因
而必须做某事。后接动词原形；有人称、数和时态的变化,
其第三人称单数形式为has to, 其疑问形式和否定形式要借
助于助动词do或does来完成。例如：
?We have to look after our sister at home.
?Does he have to get up early tomorrow morning?
?I don’t have to stay at home today.
have to 的用法
1. have (has) to + 动词原形
? have (has) to 后面要用动词原形。当主语为第三人称单数时用 has to，当句子是过去时用 had to。
? We have to go home now.
我们不得不现在就回家。
? He has to work on Sunday.
他不得不在周日工作。
? I had to do much housework last Sunday.?
上周日我不得不做很多作业。
2. have to 的否定句句型：
主语 +don’t/didn’t/doesn’t won’t +have to + 动词原形
? You don’t have to walk so fast.
你不必走那么快。
? He will not have to buy a new coat next year.
明年他没必要买新外衣了。
3. have to 的疑问句句型：
Do/Does/Did/Will + 主语 + have to + 动词原形
Did he have to ask the question?
他非要问那个问题吗？
Yes, he did. 是的。 No, he didn’t (have to). 不。
have to 与 must
二者都有“必须”之意,但 have to 表示“客观上的需要”,有人称和时态的变化,否定形式为 don’t / doesn’t / didn’t have to (没必要);must 表示“主观上的要求”,无人称和时态的变化,否定回答一般用 needn’t 或 don't have to (不必)。mustn’t 表示“禁止”。
We have to wear warm clothes in winter.
冬天我们不得不穿上暖和的衣服。 (客观需要)
I must finish my homework first before I watch TV.
看电视前我必须先完成作业。(主观要求)
比一比
You don't have to tell him about it.
你没有必要把此事告诉他。
You mustn't tell him about it.
你一定不要把这件事告诉他。
- Must I be home before eight o’clock?
8点之前我必须回家吗？
- Yes, you must.
- No, you needn‘t. / No, you don’t have to.
是的，必须回家。/不，不必。
