您好，以下是一些常见的doing和to do的固定搭配：

1. Doing：

- doing homework

- doing sports

- doing housework

- doing yoga

- doing exercise

- doing a project

2. To do：

- to do list

- to do homework

- to do laundry

- to do dishes

- to do shopping

- to do research

注意：有些动词既可以用doing也可以用to do搭配，例如：read，write，study等。

初一的：后面只用doing的有：enjoy doing sth.“享受做某事”finish doing sth.“完成做某事”keep doing sth.“保持做某事”后面只跟to do的有：learn to do sth.

“学做某事”help to do sth.“帮助做某事”want to do sth.“想要做某事”hope to do sth.“希望做某事”两个都能跟的有like doing（喜欢做某事,长期喜欢）

like to do sth（喜欢做某事,短期）stop to do sth（停下来去做另一件事） stop doing sth（停止正在做的事）remember to do sth（记得去做某事） remember doing sth（记得做过某事）forget to do sth（忘记去做某事。

hope to do sth
