英语感叹句的组成，用法及例句

对于名词的感叹，要分可数名词和不可数名词
对于可数名词 单数是what a/an (adj)+n （it is)
eg;what a smell!好难闻的味道啊
what a beautiful girl (she is)!
而对于形容词或者副词则需要用how
eg;how beautiful she is!
how fast he runs!

组成：
一、由感叹词what引导的感叹句。
1.① What+a/an+（形容词）+单数可数名词+主语+谓语！
② What+名词词组+主语+谓语！
如: What a fine day it is!
2. What+(形容词）+可数名词复数或不可数名词+主语+谓语!
如: What kind women they are!
What nice music it is!
二、由How引导的感叹句。（how用来修饰形容词、副词或动词。）
1.How+形容词（副词）+主语+谓语！
如: How hard the workers are working!
How clever the girl is!
How quickly the boy is writing!
2. How+主语+谓语！
如：How time flies! 时光飞逝!

用法：

1. 当how修饰动词时，动词不跟着感叹词提到主语之前。
如: How fast the runner runs!
2. how与what引导的感叹句中的第一种格式(单数名词)一般情况下可以相互转换，转换后意义不变。
如: What an interesting story it is! = How interesting the story is!
What a beautiful building it is! = How beautiful the building is!
3. 在口语中，感叹句的主语和谓语常常省略。
如: What a nice present!（省略it is）
How disappointed!（省略she is或其它可作本句主、谓的词语）

例句：
What a clever boy he is! (他是个)多么聪明的男孩啊!
What an interesting story it is! (这是个)多么有趣的故事啊!
What fine weather it is! 多好的天气啊!
What beautiful flowers they are! (它们是)多么漂亮的花啊!
How well you look! 你气色真好!
How kind you are! 你心肠真好!
How beautifully you sing! 你唱得真好听!
Strawberries! How nice! 草莓! 多好呀!
How clever the boy is! 这个男孩多么聪明啊!
How fast he runs! 他跑得多么快啊!
