七年级下册我们已经学过情态动词can表示能力。
can用于表示能力，意为“能，会” 。
e.g. Tom can ride a horse.
汤姆会骑马。
Revision
can表示请求时，可用来发出邀请，这时答语比较灵活。如果接受邀请，答语可用__________________ / _______________等；如果拒绝邀请，答语可用Sorry, I must / have to ... / I’m afraid not. / Sorry, I can’t. / I’m not available等。如：
通过观察和完成Grammar Focus部分的句
子，我们可以发现can在本单元表示请求
和可能性。
Discovering
Sure, it sounds great.
Sure, I’d love to.
—Can you come to my birthday party on
Monday, Bill
—Sure, I’d love to. / Sorry, I’m afraid not.
I have to go to the doctor.
其他表邀请的句型：
Could/ Will/ Would you come to my party
Would you like to/ love to come to the party
I hope you come to my party.
How/ What about coming to my party
Can you ... 意为“你能……吗？”，可用于邀请别人或委婉地请求某人去做某事。其肯定回答常用 Sure, I’d love / like to. ，否定回答常用 I’m sorry, I can’t. / Sorry, I can’t. 等。如：
-- Can you go to the baseball game
你能去参加棒球比赛吗？
-- I’m sorry, I can’t. 对不起，我不能。
Explanation
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的变化, 而have to有。它的第三人称单数为“has to”。
You / He should study hard.
你/他应该好好学习。
He has to study hard.
他不得不好好学习。
have to 的用法
（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 , does或 did 才可能完成其疑问、否定句。
试将下面三句话分别写成
（1）一般疑问句，并作肯定回答。
（2）否定句。
a. 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.
b. 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.
c. She had to study for a math test yesterday.
Did she have to study for a math yesterday
Yes, she did.
She didn’t have to study for a math
yesterday.
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”。如：
比一比
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)
You don't have to tell him about it.
你不一定要把此事告诉他。
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。
