人教版八年级上册第九单元知识点全八上unit9知识点
Unit9 Can you come to my party的知识点Grammar：1．情态动词can的用法小结：(1)表示能力，意为“能，会”，其过去式为could。
(2)表示“请求许可”。
在这一用法中，can与could都表示现在，但could比can语气更加委婉。
一般用在疑问句中，句型为Can you…？肯定回答为：Yes/Sure/Certainly，I'd love to。
否定回答常为：I'm sorry/Sorry，I can't。
(3)表示可能性，常用于否定句中。
eg：This can't be true.这不可能是真的。
2．【辨析】have to与must不必”。
have to表示客观需要，有人称、数和时态的变化；其否定形式为don't have to“must表示说话人的主观看法，认为有必要或义务去做某事，没有时态和人称的变化；其否定形式为mustn't“禁止”。
3.情态动词can表示邀请Can you ,？意为“你能,吗？”。
此句型表示客气邀请某人做某事，can可以用could替换。
区别在与：用could比用can语气委婉，显得更有礼貌。
【拓展】向别人发出邀请、请求、建议或征求某人的意见，还有几种表达方式，大多数语气比较委婉，显得客气而有礼貌。
1)Would you like,？“你想要/愿意,吗？”其后可以接名词、代词或动词不定式，用来提出建议或发出邀请。
eg: Would you like some oranges?2)Will/Would/Could you please,？“请你,好吗？”其后接名词，用来提出建议或发出邀请。
eg: Will/Would/Could you please help me sweep the floor?3)Shall we,？“我们,好吗？”shall是情态动词，其后接动词原形。
用于征求别人的意见。

重点句子点拨：
1. I'm sorry，I can't.I have to help my parents.对不起，我不能。
我得帮助我的父母。
点拨：have to 不得不，必须。
表示客观情况要求某人必须做某事，有人称和时态的变化，后接动词原形，其否定形式为don't have to。
She isn't very well these days and she has to stay at home.
她这些天身体不太好，不得不待在家里。
You don't h ave to tell me this.你不必告诉我这件事。
辨析：
have to 和must
have to强调因客观原因而“不得不”。
它有时态、人称和数的变化。
其第三人称单数为 has to，过去式为 had to。
由 have to构成的句子，进行句型转换时要借助 do，does 和did。
It's raining.I have to stay at home.
天在下雨。
我不得不待在家里。
must 强调主观上“必须”，没有人称和数的变化。
其句型变换无需借助助动词。
You must do your homework first.
你必须先做作业。
2. I'm sorry，I'm not available.很抱歉，我没空。
点拨：available adj. 有空的；可获得的
(1) 作“有空的”时，相当于free，不用于名词前。
I'm available next Tuesday if you want to meet then.
如果你想见面的话，我下星期二有空。
(2) 作“可获得的”时，常用于名词后。
I am going to send you all the stamps available.
我将把我能得到的邮票给你寄去。
3.Oh，but Sam isn't leaving until next Wednesday.哦，但是萨姆直到下周三才要离开。
点拨：until conj.& prep. 到……时；直到……为止
(1) until 用于肯定句中，意为“一直到……为止”，主句谓语动词用延续性动词。
I stayed until he came back.
我一直待到他回来为止。
(2) until 用于否定句中，构成not...until，意为“直到……才”，主句谓语动词用短暂性动词，此时until可用before代替。
I won't go there until/before he calls me.
直到他给我打电话，我才去那儿。
4.Catch you on Monday!周一见你们！
点拨：catch v. 及时赶上；接住；抓住，过去式为：caught。
