四、賓語從句結構

賓語從句的引導詞在前面的主從復合句中已經提到。這里指出的是填空題中關于賓語從句考的最多的兩個結構：　state(陳述，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：空格前的謂語動詞states一般接關系連詞that引導的賓語從句，故首先排除C。空格后已有謂語動詞，空格不應再出現謂語動詞，因此（D）正確。

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：空格處顯然缺謂語動詞indicate的賓語。（A）和（D）不能作賓語，可首先排除。（B）使句子結構混亂、語義不清，因此選擇（D），構成賓語從句。
