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。
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)
