问题 The number of cell phones ______ increased dramatically in the past few years.

选项 A、have
B、are
C、has
D、is

答案 C

解析 the number of意为“……的数量”,谓语动词用单数.例如:The number of books stolen from the library is large.(图书馆遗失的书很多。)而a number of意为“很多,计多”,它修饰的复数名词作主语时,谓语动词用复数,例如:A large number of people have applied.(很多人都已申请。)
