Explanation
1. can 的用法
（１）表邀请。
　　 若接受邀请，回答为：
　　 OK./All right./Sure./ Of course./Certainly./
Yes(Sure),I’d love(like) to.
　　 若不接受邀请，回答为：
　　 Sorry,Ｉcan’t.(+原因)
eg . Can you come to the party
Yes/Sure,I’d love/like to.
Sorry,Ican’t. 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 like /love to come to the party
3) I hope you come to the party.
4) Please come to the party.
5) How/What about coming to the party
（２）表能力“能，会”否定句 can’t不能
eg. He can swim,but I can’t.
How long can you stay under water
（３）在否定句，疑问句中表示“不可能”或“一定不”
eg. Can he come No,he can’t come.（他会来吗？不，他不能来．）
2.情态动词“have to”与其他的情态动词如：“can” , “may” “must”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 can’t 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要加助动词did,还原 have to
才可能完成其疑问、否定句。
试将下面三种话分别写成
（1）一般疑问句，并做肯定回答。
（2）否定句。
1: They have to go to the party .
Do they have to go to the party
Yes , they do .
They don’t have to go to the party.
2：He has to go to see the doctor .
Does he have to go to see the doctor
Yes , he does .
He doesn’t have to go to see the
doctor .
3： She had to have a piano lesson yesterday.
Did she have to have a piano lesson
yesterday
Yes, she did .
She didn’t have to have a piano
lesson yesterday.
2　.have 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,he’ll 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 must./No,you needn’t(don’t have to).
You mustn’t play football in the classroom.

housework .

the housework .
