Donny在北京学汉语，他的中国朋友要是遇到了不知道用美语怎么说的词，就会来请教他。今天是琼燕要问的：电灯泡。

QY: Happy Friday， Donny! 你今天晚上有什么计划吗？

Donny: Hmm, not yet. What do you have in mind?

QY: Let's go salsa!! 我今晚要跟两个朋友去跳salsa, 可他们俩是一对，我可真不想夹在中间，当大电灯泡--very bright light bulb!

Donny: I see. You don't want to be the third wheel.

QY: The third wheel?

Donny: Yep! Wheel is spelled w-h-e-e-l. The third wheel, 第三个轮子, it's a very colloquial way of saying a third person joining a couple in a social context.

QY: 没错！我就是不想当 the third wheel!

Donny: Exactly, you wouldn't want to bother any love birds, right?

QY: Wait! Love birds? 爱的鸟儿？

Donny:Yep! In English, we often use the word love birds to refer to a couple who are openly affectionate, especially in public. 就是大庭广众之下卿卿我我。你不想打扰这对love birds吧?

QY: 可不是吗！不过这两个人很配！They are a great match!

Donny: Oh that's nice! You can also say, they are a match made in heaven.

QY: A match made in heaven？ 那不就是中文里说的天生一对嘛！

Donny: There you go! Since you don't want to be the third wheel, I will go with you! But first, let's see what you learned today!

QY: 第一：电灯泡叫做：the third wheel;

第二，如胶似漆的情侣，可以说 love birds;

第三，"天生一对"是，a match made in heaven.
