感叹句通常有what, how引导，表示惊叹、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：
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。
