一个初三英语感叹句的问题

由感叹词what引导的感叹句.what修饰名词或名词短语,有以下两种形式：1.What+a(an)+（形容词）+单数可数名词+主语+谓语!如：What an apple this is!What a fine day it is!2.What+(形容词）+可数名词复数或不可数名词+主语+谓语!What kind women they are!What nice music it is!由How引导的感叹句.how用来修饰形容词、副词或动词.其结构是：How+形容词（副词）+主语+谓语!How hard the workers are working!How clever the girl is!How quickly the boy is writing!注意：当how修饰动词时,动词不跟着感叹词提到主语之前.How the runner runs!what与how引导的感叹句,一般情况下可以相互转换,转换后意义不变.如：What an interesting story it is!==How interesting the story is!what a beautiful building it is!==How beautiful the building is!在口语中,感叹句的主语和谓语常常省略.如：What a nice present!（省略it is） How disappointed!（省略she is或其它可作本句主、谓的词语）
初中水平应该就是最基本的这两种了吧.希望能够帮到你.我说的不是这个，问的是哪些不可数名词加了形容词要加a，那些永远不加a不可数名词加了形容词就一定要有量词了。例如：a piece of good news.那些永远不加a ???
