选A 这是一个感叹句 What的用法 1、What+a+可数名词+主语+谓语 2、What+不可数名词+主语+谓语 所以是What bad weather! (这里weather是不可数,所以用第2种,同时,这句话也可为:What bad weather it is!) How的用法 How+形容词+主语+谓语 例:How tall the boy is!
答案为A 感叹句的两种类型: How+形容词或副词+主语+谓语 如:How clever the boy is! How fast he is running! What+名词短语+主语+谓语(此结构中的主语,谓语可以省略) 如:What nice weather it is! What good children they ...
what a + 可数名词不可数名词 例:what a healthy girl she is ! what great fun it is ! (fun 为不可数名词,前面不加修饰的冠词aanthe) how + adj. + 可数名词 例:how healthy the girl is ! 因此,你上面的那道题目应该选A,它是省略了it is 的感叹句。
