感叹句结构,

一、由感叹词what引导的感叹句.
1.① What+a/an+（形容词）+单数可数名词+主语+谓语!
② What+名词词组+主语+谓语!
如: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!
如:What kind women they are!
What nice music it is!
二、由How引导的感叹句.（how用来修饰形容词、副词或动词.）
1.How+形容词（副词）+主语+谓语!
如:How hard the workers are working!
How clever the girl is!
How quickly the boy is writing!
2.How+主语+谓语!
如：How time flies!时光飞逝!
三、注意:
1.当how修饰动词时,动词不跟着感叹词提到主语之前.
如:How fast the runner runs!
2.how与what引导的感叹句中的第一种格式(单数名词)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!
3.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）
