一个人在消磨时间的时候往往都会做一些轻松开心的事。'To while away the time' 纯粹是为了放松而放松或者是以轻松的方式消磨时间以便等待其他事情。

例句

The film doesn't start for another hour. Why don't we while away the time with a walk in the park?

When I was a teenager I used to while away the time listening to music in my room. 

请注意

如果一件事做起来值得，有益处，就可以用“worth your while”来表达。不过，你会发现这个短语多用于否定句，说明没价值，不值得。 

例句

It's not worth your while going all the way into university for the meeting. It'll only take about 10 minutes. Let's do it online.

It's not a great job. The pay is really bad and it's only a two-week contract. I don't think it's even worth your while filling out an application.
