问题
选择题
The number of people invited __________fifty, but a number of them__________ absent for different reasons.
A．were; was
B．was; was
C．was; were
D．were; were
答案
答案：C
题目分析：考查主谓一致：第一空填was，因为主语是The number of people“人们的数量”，后面接单数谓语，第二空填were，因为主语是a number of them“他们中的很多”，后面接复数的谓语。句意是：被邀请的人的数量是50，但很多人因为各种原因缺席了。选C。
点评：主谓一致的考点较多，有的也容易混淆，平时多记多背，多做此类练习会很有帮助
