四、賓語從句結(jié)構(gòu)
賓語從句的引導(dǎo)詞在前面的主從復(fù)合句中已經(jīng)提到。這里指出的是填空題中關(guān)于賓語從句考的最多的兩個結(jié)構(gòu)： 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(guān)系連詞that引導(dǎo)的賓語從句，故首先排除C?？崭窈笠延兄^語動詞，空格不應(yīng)再出現(xiàn)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(jié)構(gòu)混亂、語義不清，因此選擇(D)，構(gòu)成賓語從句。
