问题描述:
The teacher told students not to swim in the river,____ ___?
答
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。
答
didn't he
答
did he?
答
did he? didn't he?均可
答
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?
