怎样改英语感叹句有两个问题,一个是“He plays the violin very well"(该感叹句）还有是“She is clever”急~

How well he plays the violin ！
How clever she is ！
What a clever girl she is!
What + a + 形容词 + 名词单数 (+ 主语+动词)！
What a beautiful girl she is!
What + 形容词 + 名词复数 (+ 主语 + 动词)！
What beautiful girls they are!
What + 形容词 + 不可数名词 (+ 主语 + 动词）！
What delicious milk it is!
How + 形容词/副词 (+ 主语 + 动词）！
How beautiful this girl is!
以上有点麻烦，简单记：
把感叹句从后面把主语和谓语（句子）挑出，然后看前面的感叹部分，若有名词，就用what；若无，就用how。但是注意单数时候：what a careful student she is! = How careful a student sh is!
练习：
_____nice it is today!
_____ a nice day it is today!
_____ ugly animals they are!
Keys: How; What: what
What a big box it is! == How big the box is!
What nice weather it is!== How nice the weather is!
What clean rooms they are!== How clean the rooms are

13.2 感叹句结构

感叹句通常有what, how引导，表示赞美、惊叹、喜 悦、等感情。
what修饰名词，how 修饰形容词，副词或动词，感叹句结构主要有以下几种：
掌握它的搭配，即掌握了感叹句的重点。
How +形容词+ a +名词+ 陈述语序
How+形容词或副词+ 陈述语序
What +名词+ 陈述语序
What+a+形容词+名词+ 陈述语序
What+ 形容词+复数名词+ 陈述语序
What+ 形容词+不可数名词+ 陈述语序
How clever a boy he is!
How lovely the baby is!
What noise they are making!
What a clever boy he is!
What wonderful ideas (we have)!
What cold weather it is!
感叹句的省略形式为：
What a clever boy (he is)!
典型例题
1）___ food you've cooked!
A. How a nice B. What a nice C. How nice D. What nice
答案D. 由于How 修饰形容词，副词；what修饰名词。且food为不可数名词，因此A，B 排除。C How + adj. 后面不能再加名词，因此只有D正确，其句型为What + adj. +n. (不可数)
2）___terrible weather we've been having these days!
A. What B. What a C. How D. How a
答案A. weather为不可数名词，B，D排除。C为how + adj. 后面不应有名词。只有A，符合句型What +形容词+不可数名词。
3) --- _____ I had!
--- You really suffered a lot.
A. What a time B. What time C. How a time D. how time
答案A. 感叹句分两类：
1：What + n.+主谓部分
2：How + adj. / adv. / v.+主谓部分。本题属第一种，但省略了bad，相对于 What a bad time I had! 这是个习惯用语。

How well he plays the violin!
How clever she is!
感叹句的基本句型：
How+adj/adv+主语+谓语动词
How +陈述句 （How time flies!)
What+a/an+adj+单数可数名词+主语+谓语动词
What+adj+不可数名词(复数名词）+主语+谓语动词
祝你进步！

How well he plays the violin!
How clever she is!

How well he plays the violin
How clever she is

How well he plays the violin ！
How clever she is ！
What a clever girl she is!
How+adj+主语+谓语动词
What+a/an+adj+单数可数名词+主语+谓语动词
What+adj+不可数名词+主语+谓语动词

How well he palys the violin!
How clever she is!
感叹句的口诀：名词词组跟what，how形副紧相连
也就是说what是修饰名词或名词词组，how是修饰形容词或副词
