请问感叹句的How,What a,What用法有什么区别.

What和how引导感叹句的区别- 一、 由"what"引导的感叹句："what"意为"多么"用作定语,修饰名词（被强调部分）,单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词.这类句子的结构形式是：what+(a/an)+adj.+n.+主语+谓语+(it is).如：① What a clever girl she is!多么聪明的姑娘呀!② What an interesting story it is!多么有趣的故事呀!③ What good children they are!他们是多么好的孩子呀!④ What beautiful flowers they are!多么漂亮的花呀!⑤ What delicious food it is!多么有味的食物呀!⑥ What heavy snow it is!多么大的雪呀!二、由"how"引导的感叹句："how"意为"多么",用作状语,修饰形容词或副词（被强调部分）.如果修饰形容词,则句中的谓语动词用系动词；如果how修饰副词,则句中的谓语动词用行为动词,这类句子的结构形式是：How+adj.（adv.）+主语+谓语+(it is).如：① How cold it is today!今天多么冷呀!② How nice the pictures are!多么漂亮的图画呀!③ How happy they look!他们显得多么高兴呀!④ How well she sings!她唱得多好呀!⑤ How hard they are working now!他们干得多么起劲呀!三、在表示同一意义时,英语感叹既可用"what"引导,也可用"how"引导.如：① What a hot day it is!How hot the day is !多么热的天气呀!② What tall buildings they are!How tall the buildings are!多么高的楼房呀!③ What bad weather it is!How bad the weather is!多么糟糕的天气呀!④ What bright sunshine it is!How bright the sunshine is!多么明亮的阳光呀!四、感叹句在表示激动强烈的感情时,口语中常常采用省略句,其后面的主语和谓语往往略去不讲.如：① What a fine day!多么晴朗的天呀!② What an honest boy!多么诚实的孩子呀!③ What red apples!多么红的苹果呀!④ How cool!好凉快呀!⑤ How wonderful!精彩极了!五、do with 常与连接代词 what 连用,而 deal with 常与连接副词 how 连用,如：I don’t know how they deal with the problem .(= I don‘t know what they do with the problem .)我不知道他们如何处理这个问题.
