both和either的区别

Question

如题所述

Answer 1

主要的区别是：both与复数连用，either与单数连用。
Both the boys are clever. 两个男孩都很聪明。
Either of the two boys is clever. 两个男孩都很聪明。
There are flowers on both sides of the street.
(两岸)
There are flowers on either side of the street.
(岸的两边)
路边长满了野花。

当然我们可以根据句子要表达的内容来决定是不是能替换。
① There are two apples on the table; you can take either of them. 桌上有两只苹果，随你拿哪一只。
② There are two apples on the table; you can take both of them. 桌上有两只苹果，你可以把两只都拿去。
分析：1 和2不能替换
③ There are trees on either side of the street. 街的两边（每一边）绿树成荫。
④ There are trees on both sides of the street. 街的两边绿树成荫。
分析：3和4是可以替换的，

Either A or B will attend the meeting. 不是A出席，就是B出席。两个去一个。
