You shall not fiddle away your spare time.

你不该浪费你的业余时间。

We need an experienced player who can fiddle away for hours for the country dancing.

我们需要一位有经验的、能够为乡村舞蹈连续拉好几个小时的小提琴手。

And, at the age of two, quite content to "durdle" away to herself or fiddle with a bunch of keys, Yvette was as happy as any toddler I had ever seen.

当两岁的Yvette自得其乐地‘嘚嘟’着或摆弄着一串钥匙时，她和我所见到的任何一个孩子一样是快乐的。
