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。)
