"错误"怎么说？相信很多人都会想到mistake，今天我们来给大家介绍一个口语中常用的词：booboo。
我们来看个例子：
a: how did you do on the exam?
考试考得怎么样？
b: oh, you won't believe it. i got all the questions right at first, and then i decided to go back and make some changes. guess what? i ended up getting five booboos. i'm kicking myself for that. 噢，你不会相信的。我起先全部答对了。后来决定跑回去改一下。你猜怎么样？结果我错了五题。我怪死自己了。 |
