Unit9 Can you come to my party的知识点
Grammar：
1．情态动词can的用法小结：
(1)表示能力，意为“能，会〞，其过去式为could。

(2)表示“请求许可〞。

在这一用法中，can与could都表示现在，但could比can语气更加委婉。

一般用在疑问句中，句型为Can you…？肯定答复为：Yes/Sure/Certainly，I'd love to。

否认答复常为：I'm sorry/Sorry，I can't。

(3)表示可能性，常用于否认句中。

eg：This can't be true.这不可能是真的。

2．【辨析】have to与must
have to表示客观需要，有人称、数和时态的变化；其否认形式为don't have to“不必〞。

must表示说话人的主观看法，认为有必要或义务去做某事，没有时态和人称的变化；其否认形式为mustn't“禁止〞。

3.情态动词can表示邀请
Can you …？意为“你能…吗？〞。

此句型表示客气邀请某人做某事，can可以用could替换。

区别在与：用could比用can语气委婉，显得更有礼貌。
