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.

whom 和who的区别是 whom 是who的宾格，但是在现代英语中who也可以做为宾格 但是考试还是分开来的。
what 后面一般加一个名词短语 what a fine day it is
How 后面一半加形容词或者副词（副词的感叹句只能用how) How fine the day is

what good time they are having at the party now!
what 后面接名词，how 后面接形容词或副词。例句如下：
What a nice watch it is ?
How slow he runs !
