看美劇，看電影過程中，我們經常會遇到一些只看得懂字面意思，卻無法理解的詞組或句子，這些往往是「俚語」。俚語可以讓說話變得更「生動」更「流利」。俚語比喻一般比較「誇張」，所以很適合用來表達自己的心情和想法。就像中文裡的「哇塞」、「不靠譜」等，這類的語言都是學校裡不會教的，因為他們不夠正式。
接下來，就為大家介紹美國人最常用的10個俚語！
1.In The Nick Of Time

這個傷者已經奄奄一息了，但是救護車在最後一刻趕到了！護理人員把他從死亡邊緣拉了回來。
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.

"要以命償命，以眼還眼，以牙還牙，以手還手，以腳還腳。" 。漢語中"以眼還眼"、"以牙還牙"即源於此，表示"以其人之道還治其人之身"。
