1、Can you come to my party?,Unit 9,the day after tomorrow 后天yesterday 昨天the day before yesterday 前天 two days ago 两天前the year before last 前年after three weeks=three weeks later 三个星期后 in two years 过两年,3.询问“星期”的句型:What day is(it)today?Its Monday.在英语中表示“星期”的词有：Monday 星期一;Tuesday 星期二;Wednesday 星期三;Thursday
2、星期四；Friday 星期五;Saturday 星期六；Sunday 星期日,Today we have learnt how to say“yes”or“no”to someones invitation and give a reason.,1)Can you?常用于发出邀请.在口语也用would you like to?Could you?,2)Sure,Id love to.这是对邀请的肯定回答,表示接受邀请.Sure用于口语,相当于Certainly,yes.,3)Sorry,I cant.是对邀请的否定回答。Have to“不得不,必须”,三单用has to.,Summary an
3、d homework,Explanation,1.can 的用法（）表邀请。若接受邀请，回答为：OK./All right./Sure./Of course./Certainly./Yes(Sure),Id love(like)to.若不接受邀请，回答为：Sorry,cant.(+原因)eg.Can you come to the party?Yes/Sure,Id love/like to.Sorry,Icant.I have to help my parents.,其他表邀请的句型:1)Could/Will/Would you come to the party?2)Would you l
4、ike/love to come to the party?3)I hope you come to the party.4)How/What about coming to the party?（）表能力“能，会”否定句 cant不能 eg.He can swim,but I cant.（）在否定句，疑问句中表示“不可能”或“一定不”eg.Can he come?No,he cant come.（他会来吗？不，他不能来）,2.情态动词“have to”(意思是“必须、不得不”，往往强调由于客观原因而必须做某事。have to后接动词原形)与其他的情态动词如：“can”,“may”“must”
5、和“should”不同。（1）这4个情态动词没有人称和数的变化,而have to有。它的第三人称单数为“has to”,过去时为had to,如：,He should study hard.他应该好好学习。He has to study hard.他不得不好好学习。,（2）这4个情态动词在一般疑问句中将它们放在句首,在否定句中直接在他们后边加not即可。,我们以can为例:Can he go with us?他能和我们一起去吗？He cant go with us.他不能和我们一起去。而“have to”要加助动词do,has to要加助动词does,还原 have to had to要加助动
6、词did,还原 have to 才可能完成其疑问、否定句。,3have to强调客观上需要做某事，即表示外界条件的需要不得不做某事，含有“客观所迫”的意味，它有人称和数的变化，可用于多种时态中，否定式为“不必”。must强调说话者主观上认为必须做某事，含有“主观判断”的意味，它的否定式意为“禁止，不允许”。eg.If one gets ill,hell have to see a doctor.She has to go to school by bus.We must go to school on time.-Must I finish the homework now?-Yes,you
