OK, let's recap the vocabulary from this programme, starting with mucking about, an informal way to say playing with something carelessly, not for a serious reason.

好的，让我们回顾一下今天节目中的词汇，从鼓捣开始，这是一种非正式说法，指的是漫不经心地摆弄某物，不是出于正当理由。

You " monkey around" with something when you do not know what you are doing. You are touching or playing with something you should leave alone.

当你不知道自己在干嘛时，你就是在monkey around。当你应该出门的时候你在玩弄别的东西。

If you play with something, you're constantly touching it. Like when someone plays with her hair. We also use this with 'idea' in the phrase 'playing with the idea'.

Play with的意思是不断地触碰某物。有人在玩弄她的头发。我们经常把它和idea连用playing with the idea。
