他每天不做他的家庭作业,为什么是he doesn't do his home work every day而不是 he doesn't does his homework every day

问题描述:

他每天不做他的家庭作业,为什么是he doesn't do his home work every day
而不是 he doesn't does his homework every day

因为否定后面动词用原形

因为根据语法,前面单三已经用了单三形式,后面的动词就不能用单三形式了,两者不可兼得吗!DOES的原形是DO,所以用DO,而不用DOES!

这问题问得有点意思哈!

does或doesn't后面要加动词原型

does或doesn't后面要加动词原型
does的原型是do,所以用do,而不用does

DO 助动词后加动词原形
