四、宾语从句结构

宾语从句的引导词在前面的主从复合句中已经提到。这里指出的是填空题中关于宾语从句考的最多的两个结构：　state(陈述，表明)+that 　 indicate(指明,表明)+that

例1：The quantum theory states ___, such as light, is given off and absorbed in tiny definite units called quanta or photons. 　　　
(A) energy that 　　　 (B) that it is energy 　　　 (C) it is energy 　　　 (D) that energy

分析：空格前的谓语动词states一般接关系连词that引导的宾语从句，故首先排除C。空格后已有谓语动词，空格不应再出现谓语动词，因此（D）正确。

例2：Studies of the gravity field of the Earth indicate___yield when unusual weight is placed on them. 　
(A) although its crust and mantle 　　 (B) its crust and mantle to 　　 (C) that its crust and mantle 　　 (D) for its crust and mantle to

分析：空格处显然缺谓语动词indicate的宾语。（A）和（D）不能作宾语，可首先排除。（B）使句子结构混乱、语义不清，因此选择（D），构成宾语从句。
