把They are happy.改为感叹句是:How happy they are!英语句子的感叹句是由what和how引导,what修饰名词,how修饰动词、形容词、副词和句子。
一.What+形容词+名词+主谓!二. How+形容词/副词+主谓!They are happy.这个句子是主系表结构。主语是they,谓语是are,表语是happy。主谓部分以外剩余的部分是作表语的形容词happy,所以这个句子只能用how 引导。例句:
1. What an intetesting story it is!2.What fresh fruits thry are!3.What hot weather it is!4.How slow he ran!
