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.
定语从句（Attributive Clauses）在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词.定语从句通常出现在先行词之后,由关系词（关系代词或关系副词）引出.
关系代词有：who, whom, whose, that, which等.
关系副词有：when, where, why等.
