Question

He is the only one of those clerks ________ to the important conference.

A．who was inviting	B．who were invited
C．who has been invited	D．who have been invited.

Answer 1

C

试题分析：句意：他是唯一的一个被邀请参加重要会议的办事员。这里是定语从句，先行词是the only one，因为主句用的是is，invite与主语之间是被动关系，故排除A，who在从句中作主语，谓语动词的单复数应与先行词一致，所以应该用单数，故排除BD，故选C。
点评：本题难度适中。定语从句是高中阶段的重难点之一，也是高考的热点，需要考生有分析理解句子的结构的能力，牢记关系词的用法及区别。
即学即练：The Chinese government has made the Mid-Autumn Festival a legal
holiday, ______ people will have a day off.
A. when           B. which          C. where        D. what
解析：A。句意：the Mid?Autumn Festival为先行词，指时间在从句中作时间状语，因此引导词用when。
