问题描述:
He has to do homework for an hour day every day改为否定句
答
He doesn't have to do homework for an hour every day.
原句中多打了一个day吧,应该是He has to do homework for an hour every day.
答
has to是have to的单数第三人称形式,是普通动词,day every day?是多打了个day了吧?every day 说明是一般现在时,所以加 doesn't
He doesn't have to do homework every day.他不必每天都做作业做一个小时。
答
He doesn't have to do homework for an hour day every day
