both+ 复数名词 both 是形容词,做定语；
there are high buildings on both sides of the road.
both...and...both 是连词,引导两个并列成分.
both his father and his mother are doctors.

楼主，请看下面的解释：
选 C ，因为both后面必须是复数，那么为什么选C呢？
如果用B，那么他的正确格式应该是：there are lot of beautiful trees on both sides of the road.

说得通，相当于both A and B. 但意思就不一样了：
选B： 道路的两边都栽有很多漂亮的树木。
选C： 道路的这边或那边栽有很多漂亮的树木。
想想实际情况，一条路不见得两边总能同时栽得上树木吧？

c,你看side是单数就知道了,单数用either...or...
a应该是: neither...nor...
