看美剧，看电影过程中，我们经常会遇到一些只看得懂字面意思，却无法的词组或句子，这些往往是“俚语”。
什么是俚语？
俚语就是美国人生活里常用的语言，“非正式”语言。
俚语可以让说话变得更“生动”更“流利”。俚语比喻一般比较“夸张”，所以很适合用来表达自己的心情和想法。就像中文里的“哇塞”、“不靠谱”等，这类的语言都是学校里不会教的，因为他们不够正式。
接下来，就为大家介绍美国人最常用的10个俚语！
1.In The Nick Of Time
Meaning： At the last moment, just before something bad happens
意思：在最后一刻，来的正是时候。

2. We ran as fast as we could toward the bus stop and got there just as the bus was pulling to a stop. We got there in the nick of time.我们以最快速度朝汽车站跑去，当我们到了车站时，汽车正好停了下来，我们到的正是时候。
