我们来看看例子：

Wilson医生有两个孩子，他们都结婚了。
Would you like coffee or tea? You can have either.==（either=coffee or tea）
你想要喝咖啡清空是喝茶呢？--你可以选两者中的一个。
Do you want to go to the cinema or the theatre?
--Neither. I want to stay at home.(Neither= not the cinema or the theatre)
都不想要。我想要呆在家里。
both，either，neither都可以与名词搭配
both 复数名词，比如：
both girls/ books/ cars......
either/ neither 单数名词，比如：
我们一起来看看例子：
I decide to go to Italy and Paris this year. I like both cities very much.
