考點三 連接從句或不定式
介詞之后還可以接賓語從句或不定式短語，但要借助于
連接代詞 (如：what , which, whom)
或連接副詞 (如：how, when，where)
例句： I knew nothing about how he got the green card.
She’s pretty hesitant about which one to choose.
例題：
(1)
The Cubists were concerned with how----a given subject from different points of view simultaneously.
(A) represented
(B) do they represent
(C) to represent
(D) representing
答案：C
解釋：介詞with后面的賓語不完整, C 是不定式短語作賓語. A D都不足以和how構成賓語從句; B不應用疑問句語序, 若去掉do則是正確的
(2)
The scholarly interest in perception stems largely from questions about the sources and validity of what ----.
(A) it is known as human knowledge
(B) is known as human knowledge
(C) known human knowledge
(D) is human knowledge known
答案：B
解釋：介詞of的賓語殘缺, B 構成賓語從句, 包含短語be known as；A多主語it; C 無法與what契合; D 語序錯誤
注意：介詞后面不能夠接 that 所引導的從句，除非in that連起來作為特殊的狀語從句引導詞，表原因
(3) (Exer1_21_31)
Soprano Julia Migenes-Johnson believes in that her Latin American background helped her interpret the role of the Spanish character Carmen in a 1984 opera film.
應改為：believes
解釋：介詞后面一般不能夠接that 引導的從句。除非in that連起來
(4)
Hovercraft, or air-cushion vehicles, are unusual ---- travel over land and water on a layer of air .
(A) they
(B) in they
(C) that they
(D) in that they
答案：D
解釋：空格前是句子的主謂語，空格后是謂語結構，空格處需要從句引導詞及從句主語，只有D符合題意，in that是特殊的狀語從句引導詞，表原因
詞匯：hovercraft: 水翼船, cushion: 墊子
