Question

He ended his speech with a remark_______ knowledge _______power.

A．which; was

B．that; is

C．which ; is

D．that ; was

Answer 1

B

试题分析：remark是先行词，后是一个同位语从句，knowledge is power知识就是力量。这是一个名言，用一般现在时，从句中不缺成分，所以用that，它在同位语从句中不作成分。故选B。
点评：本题难度适中。同位语从句是高中的重难点之一，需要考生必须有分析理解复杂的句子结构的能力，还必须能够理解句意。弄懂定语从句和同位语从句的区别。
即学即练：I am well aware ______ this is a tough job.
A. which    B. that      C. what      D.whose
解析：B。句意：我深知这是一件棘手的工作。
