[谚]有志者， 事竟成。 3.关系副词why引导定语从句时， 先行词常常为reason， 关系词在从句中作原因状语。 Unsuccessful people can always find reasons why（＝for which）they’re not doing well. 不成功的人总能找到自己表现不好的理由。 [对点训练1] 用适当的关系副词填空 ①He lived in a time 　when　 the blind couldn’t get much education. ②Can you tell me the company 　where　 she works？ ③This is the reason 　why　 he left in a hurry. ④Nowadays people are more concerned about the environment 　where　 they live. ⑤The film brought the hours back to me 　when　 I was taken good care of in that faraway village. 要点二　注意事项 表示时间、地点及原因的名词作先行词时， 定语从句可用关系代词引导， 也可用关系副词引导。若先行词在定语从句中作状语时， 应用关系副词；若先行词在定语从句中作主语或宾语时， 则应用关系代词。 The custom dates from the days when women wore longer skirts. 这种习惯始于妇女穿较长裙子的时期。（when在从句中作状语） The music calls up the happy days which/that they spent together in their youth. 音乐使他们想起青年时代一起度过的快乐日子。（which/that作spent 的宾语） The reason why we want to come to this store is that we really want this kind of phone. 我们想来这家店的原因是我们真的很想要这种手机。（why在从句中作状语） This is the reason that/which he explained to me for his not attending the meeting. 这就是他向我解释的不参加会议的原因。（定语从句中explained缺少宾语， 所以用that/which引导从句， 不用why） [对点训练2] 对比填空 ①Do you still remember the days 　that/which　 we spent together on the farm？ ②Do you still remember the days 　when　 we chatted with each other all night？ ③He works in the factory 　that/which　 makes bikes. ④He works in the factory 　where　 bikes are made. ⑤The reason 　that/which　 he explained at the meeting was not sound. ⑥The reason 　why　 he was late was that he missed his train.
