_____the doctors in the hospital is about100 and one fourth of them are _______doctors.
A．A number of; manB．The number of; men
C．A number of; menD．The number of; man
B

试题分析：句意：这家医院的医生数大约有100人。四分之一是男医生。分析：1.the number of…表示“……的数量”。作主语的中心词时，谓语动词用单数形式，后常跟large, small等词作表语。 2.a number of表示“若干的、许多的”。起修饰作用，相当于many或a lot of，number前可以加small, large词来表示程度。A number of+复数可数名词作主语时，其谓语动词用复数形式。同时考查：以man或woman为定语时，前后两个名词都变复数.故选B
