趁……还好

while the going is good

If you say that someone should do something while the going is good, you are advising them to do it while things are going well and they still have the opportunity, because you think it will become much more difficult to do.

如果你对某人说你应该做某事while the going is good，意思就是你建议某人趁着时机还好，还有机会赶紧去做某事，因为你认为错过现在以后就会更困难了。翻译为：趁还有机会时；趁情况还有利时；趁形势还未发生变化时。

例：

There's no traffic right now, so if you're driving, you should get going while the going is good.

现在不堵车，所以如果要开车，趁现在交通状况好赶紧出发。
