在定語從句中，關(guān)系代詞會(huì)出現(xiàn)“in which,on which,by which,at which,for which”等。它們的用法是什么？

介詞+ 關(guān)系代詞主要根據(jù)前邊的動(dòng)詞（通常是不及物動(dòng)詞）來確定;I want to find a room to live in。i wanted to find a room in which I can live。The bus on /in which he travelled leads to the post office 。The bus which he takes(這里不用介詞， 因?yàn)閠ake是及物動(dòng)詞）leads to the post office。The station at which he stayed was a big one。The station which he reached was a big one。 (不用介詞)。The reason for which he was late was not a good one。(=why)。The house for which they were hunting was too expensive。The house which they found/hired was near mine。(不用介詞)。。

這類的關(guān)系代詞連接定語從句關(guān)鍵看前面的先行詞和后面的從句之間的關(guān)系。如果后面的從句是在先行詞的里面，表示在先行詞的里面有什么，用in which。如果在先行詞的上面有什么用on which。如果在依靠，利用先行詞用 by which。想表達(dá)為了先行詞用for which。at which表示時(shí)間的意思相當(dāng)于when。還有during which,表示在先行詞之間。
