Wilson
Role-play the conversation and pay attention to how to make, accept and decline the invitation. Sun Ning: Hey, Ted. Can you come to my

have to 的用法
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。
（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。
c. She had to study for a math test yesterday. Did she have to study for a math yesterday?
go to the doctor
go to the zoo
A: Can you go to the zoo? B: Sorry, I can’t. I have to help my parents. A: Can he go to the zoo? B: No, he can’t. He has to help his parents.
Key sentences:
1.—Can you come to my party on Saturday? —Sure，I'd love to. /Sorry，I must study for a math test. 2.—Can she go to the baseball game? —No，she's not available. She must go to the doctor.
