what, how ,what a, how a,感叹句用法区别!
感叹句是表示喜、怒、哀、乐等感情的句子.感叹句一般用 how 或 what 开头.
一、 what 引导的感叹句结构有三种：
1． What + (a/an) + 形容词 + 可数名词单数 + 其它!
2． What + 形容词 + 可数名词复数 + 其他!
3． What + 形容词 + 不可数名词 + 其他!
例如：
(1) What a great pity you missed the lecture again!你又一次错过了讲座,真是太遗憾了!
(2) What interesting books you bought us!你给我们买的书真有趣!
(3) What fine weather it is!多么晴朗的天气呀!
二、 how 引导的感叹句结构有：
1.How + 形容词 + 主语 + 谓语!
2.How + 副词 + 主语 + 谓语!
例如：
(1) How beautiful the flowers are!这些花是多么美丽呀!
(2) How heavily it is raining!雨下得是多么大呀!
how 和 what 都用来引导感叹句,它们有什么区别呢?how 在这里是一个副词,用来修饰形容词和副词；而 what 是用来修饰名词的,所以即使是同样的句子,how 和 what 引导的句子结构是不一样的.请看下列例句：
(1) 多美丽的一朵玫瑰花呀!
How beautiful a rose it is!
What a beautiful rose it is!
(2) 多晴朗的天气呀!
How sunny the weather is!
What sunny weather it is!
(3)这些学生是多么聪明呀!
How clever the students are!
What clever students they are!
