有关反问句问题
how fast the dog runs,doesn't it
what an honest person ,isn't he
为什么第一个句子中是doesn't,第二个句子中是isn't呢?
does和is 和前面有什么关系呢?

how fast the dog runs,doesn't it ?
这狗跑得多快啊!不是吗?主语是狗,it指代的是狗,run是动词,所以反问用doesn't it?换成正常语序你就很容易明白了:
The dog runs very fast, doesn't it?
what an honest person ,isn't he ?
他是多么诚实的一个人啊!难道不是吗?
正常语序:
He is a very honest person, isn't he?

第一个是主谓宾结构 第二个是主系表结构

honest是形容词,第二句中后面省略了he is ,全句应为what an honest person he is ,isn't he?
第一句中的run是实意动词,所以后面是do+es(三单)后变否定doesn't
而honest是形容词,用is修饰,所以变为否定式后为isn't he
