依旧从BerkeleyX: ColWri2.2x Principles of Written English 抄过来的。我真的对这门课是相见恨晚！呜呜，我写英文各种罗嗦（楼下群众：你中文更罗嗦好不好？你看落园多少废话？）
ps 中间有段讲写作语气的我没抄过来，这个感觉和语言就无关了，更多是用词的精准...

what causes wordiness?
Wordiness is using more words than you need to in order to write what you mean. Everyone has a tendency to be too wordy at times. Some of the causes of this wordiness are:
- Trying to sound too formal or academic. Unfortunately, in academic writing, there are a lot of examples of wordy writing. This doesn't mean you have to model your writing on bad examples. Your readers will always appreciate if you state your ideas clearly, and using no more words than needed.
- Not knowing more precise vocabulary. For example, saying, She ran quickly to the store can be made somewhat less wordy, and more precise, by saying: She raced to the store (race=run quickly). Finding the right vocabulary can help you cut down the number of words you use. Every reduction helps, even if it's only a word or two.
- Using too many unnecessary and vague modifiers. Typically, modifiers like really, very, quite, and similar words add no meaning to your writing. If you need to modify a word, find precise modifiers. For example, instead of There's a really tall building near my house, write: There's a 50-story building near my house.
- Using too many prepositional phrases or possessives. These types of phrases can add length to your sentences, often unnecessarily. So, instead of The car belonging to Mr. Wang is in the garage [10 words], write: Mr. Wang's car is in the garage [7 words].
