是后者啦.因为主语是an apple,谓语动词就要用“单三形式”.但我也看到很多地方说的是后面那个再补充,我又发现一件事情,你问题里的那句是an apple a day keep the dactor away,我一看见就觉得an apple 是主语.但是,别的地方很多时候写的是 An apple a day,keep the doctor away.注意,是有个逗号的,如果有那个逗号,就不是keeps了,这句话是不是可以说成是“if you eat an apple every day,you can keep the doctor away”呢?我觉得真相很可能是这样,这句话的本来面目是带逗号的,但人们说的太快连上了,久而久之有的人把逗号忽略了,于是在语法上出现了误解.我百度一下发现人们把这句话说成三个版本：An apple a day,keep the doctor awayAn apple a day keep the doctor awayAn apple a day keeps the doctor away系我的推测啦,期待高人确证

这是一句俗语，是新版剑桥少儿英语一级第三单元的课文，选后者，用单三形式keeps才是正确的，有的时候人们应用直接用Keep是错误的！
