我想知道括号前都应填写什么答案?我可是替我儿子问的呀!请你们帮帮我!我自己学的早忘记了!谢谢了!

helped 过去式
doing 句型 with doing sth

We helped her with doing housework just now.
We helped her with the housework just now.
We helped her to do the housework just now.
We helped her do the housework just now.

helped 使用过去时描述已经发生的动作
doing 使用doing形式是因为前面是介词“with”
