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，掌握它的搭配，即掌握了感叹句的重点。感叹句结构主要有以下几种：
How +形容词+ a +名词+ 陈述语序 ！
How clever a boy he is!
How+形容词或副词+ 陈述语序!
How lovely the baby is!
What +名词+ 陈述语序!
What noise they are making!
What+a+形容词+可数名词单数+ 陈述语序!
What a clever boy he is!
What+ 形容词+可数名词复数+陈述语序!
What wonderful ideas we have!
What+ 形容词+不可数名词+陈述语序!
What cold weather it 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，相当于 What a bad time I had! 这是个习惯用语。
