大家都知道，每一门语言里都有着数不清的习语和一些比较地道的用法。一些惯用语(Idioms)如果单纯按照字面意思来理解的话，往往会和说话者的真实意图南辕北辙，特别是作为一名正在学习英语的“歪果仁”，仅仅靠字面直译的意思来理解一些表达可能会闹出笑话。

举个栗子，某天，你有一件事情需要麻烦你的朋友，你朋友欣然接受了你的请求并帮助了你。你表示万分感谢，这时候你朋友大度地说：“It’s okay, you’ve scratched my back plenty of times”。如果你只知知道scratch someone’s back 是给某人挠背的意思的话，此时此刻的你一定是一脸黑人问号的怀疑人生，并且用力思索自己到底什么时候给他挠过背。其实，这个短语的意思就是预支自己对他人的帮忙，以防日后不时之需时可以有人情债可收，也就是中文中常说的投(qian)桃(zhai)报(huan)李(qian)。

通过这个例子我们可以发现，和中文一样，英文中也有数量众多的idioms，如果望文生义，可能就会产生歧义，引起误会，在托福听力中尤为如此。平日多积累一些地道的惯用语和表达方式，不但能够帮助我们理解文章，更会在考到一些惯用语和特殊表达的题目时，内心像抽到SSR一样激动万分啊有木有!那么今天，就由我来给大家梳理托福听力中出现过的那些“土掉渣”的地道英语表达。
