Question

There are many trees on_______ side of the street, and_______ of the trees is still growing.

A．both; the number	B．either; the number
C．both; a number	D．either; a number

Answer 1

B

试题分析：句意：街道两边有许多树，并且树的数量仍在增长。Both两者都，后跟复数名词；either两者中的任何一者，后跟单数名词。The number of…的是数量，作主语时谓语动词用第三人称单数式；a number of许多，修饰复数名词。所以选B。
