Question

英语里面either的用法是什么？

Answer 1

either 在英语中属于不定代词，意思是(两者中的)任何一个， 如: You can park on either side of the street. 还可以和or 构成连词either...or..., 如: He either suffocated or froze to death. 还可以作副词用在否定句中，表示“也”，如: I can't go there, either.

Answer 2

一 either 用作代词时,意为“两者中的任何一个”,在句中可作主语和宾语.either 在句中用作主语时,谓语动词应为单数形式.例如:
Either of them can do the work. 他们两人中谁都能做这工作.
Either of the students does well in their studies. 两个学生中,无论是谁学习都不错.
—Do you like the two books? 你喜欢这两本书吗?
—No, I don’t like either. 不,哪一本我都不喜欢.
二 either 用作形容词时,意为“两者中任何一个的”“两边中任何一边的”,作前置定语用.例如:
He saw two films, but he didn’t like either one very much. 他看了两部电影,但哪一部他也不太喜欢.
On either side of the river there are some small factories. 在河的哪一边都有几座小型的工厂.
There are a lot of trees on either side of the street. 街道的两边都有许多树.
三 either 用作副词时,意为“也……”,只用于否定句中例.如:
They didn’t go to the park yesterday. I didn’t go there, either. 昨天他们没去公园,我也没去公园.
My mother doesn’t like traveling by air. My father doesn’t like, either. 我的母亲不喜欢坐飞机旅行,我的父亲也不喜欢.
