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。
PS:另外还有一种句子： What if it's raining!( 好大的雨！）不能 how， 这种用法极罕见 。
