（） your father free on sunday?yes.he ( )work at weekends.
问题描述：
（） your father free on sunday?yes.he ( )work at weekends.
A is isn't B does doesn't C is doesn't D does isn't (好像有时候问你的不是人,是一个物,可以问do答be动词)求答案可解释
答
选C
（Is） your father free on sunday?yes.he ( doesn't)work at weekends.
译：你的父亲星期天有空么?是的,他周末不上班.free 是 形容词,用be 动词修饰,your father是单数,所以用is work 是动词,用doesn't那这个句子中问的是your father 还是free ，为什么不是isn‘t workwork 工作， 是动词啊， is 是be动词，后面怎么可能加动词原形，
最多是isn'tworking 表示不正在工作
顺便问一句同学你是几年级的啊
free 是形容词，前面肯定是be动词，就像I am happy. sheissad.theyarefree
