The teacher told students not to swim in the river,____ ___?

问题描述:

The teacher told students not to swim in the river,____ ___?

应该是didn't he?这是反意疑问句“前肯后否”的形式。后面用肯定还是否定依句子前面的主干而定。句子主干是the teacher told the student,属肯定的,所以后面用否定。

didn't he

did he?

did he? didn't he?均可

这里面 只能用didn't he?
我原来见到过这样的题
这个题 的主语是The teacher 谓语动词是told 宾语是students 这三个部分构成句子的主干
后面的not to swim in the river做补充成分
所以变成反义疑问句的时候 看句子的主干
所以只能是 didn't he?
