no time to lose 

If you say there is or that you have no time to lose, it means that you must do quickly whatever it is that you want to do.

如果你說“there is/that you have no time to lose”，那么你的意思就是你必須馬上做某事，不管那是什么事，沒時間耽擱了

例：

Come on, there's no time to lose, we have to get home before John finds out.

趕快，沒有時間耽擱了，我們必須在約翰發(fā)現(xiàn)之前趕到家。

And now, without further ado, I go. There is no time to lose.現(xiàn)在，就不必再說廢話了，我走了。不能再耽擱了。

ado /?'du?/ n. 無謂的忙亂, 無謂的紛擾,費力, 艱難
