I often help my mother do some housework
housework不可数为什么用do,不用does

首先你要分清句子的结构
I often help my mother do some housework
I是主语 help是谓语 my mother 宾语 do some housework是动宾结构不定式
即help sb.(to) do sth.
而这里面的 do任何时候都是不用变形的,因为它是不定式(to) do ,不是谓语
若是一般句子例如：I do my housework
如将 I 变为 He,则 do应变为does ,因为这里do是谓语
总结：
①变不变要看是不是谓语
②怎么变要看主语,而不是do后宾语my housework
