2. 当发出邀请时，其回答分为两类。一类表示接受邀请，另一类表示拒绝邀请。
（1）常见的表示接受邀请的回答：
Yes, I’d love/like to. 是的，我很乐意。
Sure. Thanks for your invitation. 当然，谢谢邀请。
（2）常见的表示拒绝邀请的回答：
Sorry. I’m not available. 对不起，我没有空。
I’d love to, but I’m afraid I can’t. I have to revise for my test. 我很乐意去，但是恐怕不行。我不得不备考。
have to 和must的区别
have to “不得不、 必须” 强调客观需要，有人称和数的变化，其疑问式和否定式都需要借助助动词
eg. I have to go to the doctor.
He has to help his parents.
eg. Do you have to go to school in 100 years
eg. I don’t have to go to school in 100 years.
have to 和must的区别
must “必须、一定”,强调主观的义务和必要，没有人称和数的变化。疑问式must提前,否定回答常用needn’t或don’t have to,不用mustn’t
eg. Must you study for the test
No, I don’t have to./No, I needn’t.
