问题描述:

这里that was 这样用可以吗?
前提:Pls.make sure the bag is put in the box before you leaving office!
回答:Don't worry about this,that was done!

That was done的意思简单的翻译的话就是“那已经做好了”.
前提: 请在离开办公室之前把包放进箱子里.
回答: 不用担心,那已经做好了.
另外,应该是Pls. make sure the bag is put in the box before you leave the office!而不是leaving office.
还有,应该是Don't worry about that, that was done!,而不是Don't worry about this.
