either 与too的区别

either和too都可以当"也"讲,前者用在否定句中,后者用在肯定句中.
Lily likes fruit.I like fruit,too.莉莉喜欢水果,我也是.
Lily doesn't like fruit.I don't like fruit,either.
莉莉不喜欢水果,我也不喜欢.
除此之外,它们还有各自的用法.
1.either表示二者之一.
We can go to either restaurant.I don't mind.我们可以去两家饭店中的任何一家.我不再乎.
I haven't been to either of those restaurants.我没去过那两家饭店中的任何一个.
2.either.or 或者.或者
I'm not sure where he is from.He's either Spanish or Italian.
我不敢肯定他是哪人.他或者是西班牙人,或者是意大利人.
too 表示“太”,有超出极限无法忍受之意.
It's too hot in the room.I can't stay here.房间太热了.我简直呆不下去了.

最简单的区别就是看句子的陈述状态。
either否定句
too肯定句
i like red.-----i like red,too.肯定句，加逗号，too
i don't like math.------i don't like math, either.否定句，加逗号，either.
