質問: 関係詞に関する質問です。 関係詞に関する質問です。 this is the very moss in which the professor was in search. (これぞまさしく教授の探していた苔だ) という文中の[in which]は[that]に置き換えられないとのことです。 過去に[前置詞+which]は[that]に置き換えられると学んだ記憶があるのですが、 置き換えが出来るときの出来ないとき、それぞれの違いを教えていただけますでしょうか?
回答: 関係代名詞という範疇でいいますと of which = whose in which, for which,などは in that とは言いません this is the very moss of which the professor was in search. × this is the very moss of that the professor was in search. ○ this is the very moss (which,that) the professor was in search of. となります 他の例では this is the house in which he lives. this is the house (which, that) he lives in. × this is the house in that he lives.
