选择题
This is one of the best films ___________ .
A．that have been shown this year
B．that have shown
C．that has been shown this year
D．that you talked
答案
答案：A
题目分析：句意：这是今年放映的最好的电影之一。这里是定语从句，先行词是films，关系词作主语时，谓语动词的单复数根据先行词的单复数来确定。又因为films与show之间是被动关系，故选A。
点评：本题难度适中。主谓一致是高中阶段的重要的语法项目，它的各种情况比较多，需要考生牢记它们的用法，这里考生容易误选C。
即学即练：The number of people invited _____ fifty, but a number of them _____ absent for different reasons.
A.were; was B.was; were C.was; was D.were; were
解析：B。句意：the number of+可数名词复数作主语，谓语动词用单数；而a number of+可数名词复数作主语，谓语动词用复数。
