In our school library, there       a number of books on science and the number of the books        growing larger and larger.

A．is, are

B．are, is

C．have, is

D．are, are

答案

B

解析

试题分析：句意：在我们学校图书馆，有许多关于科学的书，书的数量越来越多。a number of 许多，相当于 many，修饰可数名词复数。作主语时，谓语动词用复数。number可用large，small等修饰，以表示程度。
； the number of……的数量，跟复数名词连用作主语时，中心词是number，谓语动词要用单数。故选B。
