Question

People have the belief ______ factories should produce fewer things from raw materials, ______the supply is growing smaller and smaller.

A．which; that

B．that; of which

C．that; whose

D．which; whose

Answer 1

B

试题分析：
第一空that引导同位语从句，解释说明the belief的内容；第二空which引导非限制性定语从句，构成the supply of which的结构，which指代上交的raw materials（原材料）。
句意：人们相信工厂应该更少的从原材料中生产出东西，因为原材料的供应正变得越来越少。
点评：名词性从句分为主语、宾语、表语、同位语从句四种，同位语从句和定语从句的区别在于：that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略； that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句:
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）
