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。今天是吴琼要问的：拗口。

DONNY:吴琼，What's up?

WQ:我表姐要生宝宝了，发动全家给孩子起名儿呢，这不，我翻翻字典，找点灵感。

DONNY:Interesting! 我也来出主意！

WQ:孩子姓唐，你说叫什么好？

DONNY:唐？嗯……唐 - 老 - 鸭。

WQ:啊？！

DONNY:Haha! I'm sorry, Wu Qiong. I know this is a terrible name, but when you mentioned the word“唐”， the name rolled right off my tongue.

WQ:Rolled right off your tongue? 从舌头上滚下来？我明白了，就是顺口，脱口而出。你一听到“唐”字，顺口就说出了唐老鸭。 那……如果不顺口，也就是拗口，该怎么说呢？

DONNY:You can say it's a tongue twister.

WQ:哦，tongue twister，就是说起来拗口的东西! This name is a tongue twister 这个名字真难念。

DONNY:没错! Wu Qiong, you know the luxury car brand "Mercedes-Benz", do you?

WQ:Mercedes-Benz? 就是奔驰嘛!

DONNY:Right. The Chinese translation“奔驰”rolls right off the tongue. However, if we call the brand 梅赛德斯·本兹， to me , that's a tongue twister! It's like I'm tripping over my own tongue when I try to say it.

WQ:Trip over your own tongue? 我知道trip是绊倒的意思，所以trip over one's own tongue 就是打磕巴，吃螺丝吧？

DONNY:Absolutely!

WQ:DONNY, We need to find a good name for this baby. We don't want people to trip over their own tongues when they say the baby's name!

DONNY:Of course, but first let's see what you've learned today!

WQ: 第一，顺口叫“to roll right off the tongue”；

第二，拗口的东西则是“a tongue twister”；

第三，打磕巴，吃螺丝，叫“to trip over one's own tongue”。
