生活中，需要二选一的场合很多。比如：喜欢喝茶还是咖啡？喜欢早起还是早睡？喜欢流行乐还是乡村乐？偏爱某一种？两样都爱？都无好感？
用法总结
Both vs either vs neither
All three words are used to talk about two things.
这三个词都用来谈论 “两者、两件事情”。
Both means two of two things.
限定词 “both” 的意思是 “二者都……”。
- Both tea and coffee contain caffeine.
Neither means zero of two things. We use 'neither... nor...' to specify what the two things are.
限定词 “neither” 的意思是 “二者都不”。搭配 “neither... nor...” 用来具体说明这两者是什么。
- Neither tea nor coffee contain alcohol.
Either means one of two things. We use 'either... or...' to specify what the two things are.
限定词 “either” 的意思是 “二者中的任意一个”。搭配 “either... or...” 用来具体说明这两者是什么。
- In the morning, I drink either tea or coffee.
