Accept (接受) invitations:
Sure / Yes / Of course, I’d love to. Certainly, I’d like to.

Decline (拒绝) invitations:
I’m sorry, I can’t. I have to look after my grandmother. I have to study for a math test. I am going shopping with my friend. …

Explanation
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。

单项填空 --- Can you help me with my English this weekend? --- Sorry, I ______. I have a lot of homework to do. A. can’t B. mustn’t C. needn’t D. don’t
答案:A 题意:“请问这个周末你能帮我 学习英语吗?”“对不起,我不能。我有 很多作业要做” 。不能答应他人的请求时 常用“(I’m ) Sorry, I can’t.”。

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。

试将下面三种话分别写成 (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.

比一比
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:

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。
