---May I use your mobile phone ? ---Of course you may .

--- Can I borrow your bike, Millie? ---Yes, you can. Here you are.

What a beautiful flower !

How beautiful the flower is !

语法要点：

一．can、could和may用法

1. 情态动词can 表示现在的能力，could 表示过去的能力，后跟动词原形，can do sth.=is/ am/ are able to do sth. could do sth.= was/ were able to do sth.

不能做某事can/could not do sth.= be not able to do sth.= be unable to do sth.

2.情态动词could 表示委婉语气，比用can 更加有礼貌，may 比较正式。

一般疑问句回答，通常情况问什么，答什么Can I …? Yes, you can. No, you can’t.

请注意下列特殊情况：Could I …? Yes, you can. No, you can’t.

May I …? Yes, you may. No, you can’t. (坚决拒绝No, you mustn’t.)

Must I …? Yes, you must. No, you needn’t.

3.表示可能性may be也许是，（50%）must be一定是,（100%）can’t be 不可能是（0%）。

二．感叹句

1. 用what构成感叹句是，what作名词修饰名词。

1) What + a(n) + 形容词+单数可数名词（+ 主语+ 谓语）！What an exciting game it is!

2) What + 形容词+ 复数名词（+ 主语+ 谓语）！What interesting books they are!

3) What + 形容词+ 不可数名词（+ 主语+ 谓语）！What bad weather it is today!

2. 用How构成感叹句时，How做状语修饰形容词或副词。

How + 形容词/副词+ 主语+ 谓语！How beautiful the dress is!

3. What引起的感叹句都可以转换为how引起的感叹句

1) What good news it is! ---How good the news is!

2) What beautiful flowers they are! ---How beautiful the flowers are!
