Tree and flowers are on _____ bank of the river.
A.either B.both C.any D.every

There are tall buildings on _____side of the playground.
A.all B.either C.every D.none

这两题我完全搞不懂呃，谁来帮帮我啊？？、求

Answer 1

Tree and flowers are on either bank of the river.
A.either B.both C.any D.every
两边都有花木，either 是任何一边，每一边。

There are tall buildings on _every side of the playground.
A.all B.either C.every D.none
操场两边都有高楼。如果用all，后面的side则应该用复数了：sides； either 是两边，操场有四边，所以不是它； none是否定，这样用很别扭。如果没有高楼，何不说：there is no tall buildings on any side of the playground?

追问

either好像是“两者中的任一个”的意思，怎么能表达“两边都有花木”的意思呢？也可能是我的理解有误，请您为我讲解一下！O(∩_∩)O谢谢~~

追答

这个不必纠结。either 是“两个中的任一个”，没错。具体用法：1）有时是两个之中，你可以任选一个【比如：There are two ways to go to Beijing, either you can travel on airplane or by train.】；而有时，它的意识和each一样，是“两个都”【比如：There are two roads leading to my school, one with trees on one side of it only, while the other with trees on either side of the road】。你看，两条路通往学校，其中一条路，只有一侧有树，而另一条路，路两边都有树。甭管那边（任意一边）都有树。

Answer 2

A 树木和花在河的一边 bank是单数嘛 在哪一边不知道。。。
C 操场周围高楼林立。 操场可是有四边的 用every

Answer 3

A。either这里有两者中每一方的意思。第二题应该C了
