He has to do homework for an hour day every day改为否定句

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.

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。

He doesn't have to do homework for an hour day every day
