on weekends,students should help their parents do some cieaning at home.clean为什么加ing
为什么加ing

固定搭配 do some cleaning［shopping］扫除,购物

你能看到Clean前面有Some，说明这应该是名词词性，那么当然要选用动名词Cleaning，而且这也是一个比较重要的固定用法

Do sth. 中的Sth.是名词，clean的动名词是cleaning

你好

do some cleaning 打扫卫生的意思

类似的还有：do some shopping 购物
do some running 跑步

　　do some -ing是英文中的固定搭配，因为两个动词原形不能连在一起，若想挨着排列，通常需要把后面的动词变形，to do或-ing形式，这里就是-ing形式，语法称为动名词形式。

这了cleaning是作名词，do+名词，比如：do the shopping, do the washing,这里ing结尾的词叫动名词，就是动词变成名词，当名词用
