01 Both

both表示“(两者)都”,可以代指可数名词复数,做主语时,谓语动词用主语是复数时的形式,比如:I have two sisters. Both are nice.

both也可以做限定词,限定可数名词复数,比如:Both her sisters are teachers.

另外both可以用在“both of+可数名词复数”结构里,比如:Both of her parents are teachers.

not both是both的部分否定,意思是“并非两个都”,比如:Not both of her elder sisters are teachers. 她的两个姐姐并非都是老师。

02 Either

either表示“(两者中的)任意一个”,做主语时,谓语动词用主语是单数时的形式,比如:You can stay or leave. Either is OK.

either也可以做限定词,限定可数名词单数,比如:He can write with either hand.

另外either可以用在“either of+可数名词复数”结构里,比如:You can choose either of the two dresses.

此外not … either是both的完全否定,意思是“(两者)都不”,比如:I don’t like either of the two dresses. 这两条裙子我都不喜欢。

03 Neither

neither表示“(两者中任意一个)都不”,是both的完全否定,可以代指可数名词单数,做主语时,谓语用主语是单数时的形式,比如:The two films are boring. Neither is interesting.
