选择题
The number of the people invited to the meeting ____ about 100, but a number of them ____ late because of the heavy snow.
A．were; was
B．were; were
C．was; were
D．was; was
答案
答案：C
题目分析：考查主谓一致，a number of+可数名词复数，表示“很多“，后面的谓语是复数，the number of+可数名词复数，表示“…的数量”后面的谓语是单数，所以第一空填was第二空填were，，句意：被邀请参加会议的人的数量是100人，但很多人因为大雪迟到了。
点评：考查主谓一致的考点比较多，也比较碎，平时记忆的时候要细致，这题是考单复数同形的名词，做题时结合修饰词判断是单复数，从而决定谓语的形式。
