看到这段话，来自这里：

Recently I discovered that learning a foreign language teaches you two things: how to communicate in that language and how to communicate in your own language to non-native speakers. You learn that simple grammatical structures and shorter sentences are easier to understand. You get a feeling for when someone’s following you and which words in the sentence are most important to pronounce clearly.

感觉说的很好。你需要知道如何和没有熟练掌握这门语言（或者领域）的人交流，你需要知道如用简单的表述，清晰的表达你的意思。
