在英文中，没做过的工作可以用 "uncompleted work" 来表示。

"Uncompleted" 是形容词，意思是 "not finished or not completed"。"Work" 是名词，意思是 "an activity, especially one that involves mental or physical effort done in order to achieve a result"。因此，"uncompleted work" 就是指没有完成的工作或活动。

下面是一些使用 "uncompleted work" 的英文例句及其中文翻译：

I have a lot of uncompleted work on my desk that needs to be done before the end of the day. (我桌上有很多未完成的工作需要在今天结束前完成。)

The project was put on hold because there was too much uncompleted work. (这个项目暂停了，因为有太多未完成的工作。)

I can't leave for the weekend until I finish all my uncompleted work. (在我完成所有未完成的工作之前，我不能周末离开。)
