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(gòu)成賓語從句; B不應(yīng)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(gòu)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(dǎo)的從句，除非in that連起來作為特殊的狀語從句引導(dǎo)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(yīng)改為：believes
　　解釋：介詞后面一般不能夠接that 引導(dǎo)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(jié)構(gòu)，空格處需要從句引導(dǎo)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(dǎo)詞，表原因
　　詞匯：hovercraft: 水翼船, cushion: 墊子
