1、 先观察下面各句,尝试总结一下红色部分的用法。Do you remember the days when / in which I stayed with you in the USA? 你还记得我和你在美国共度的那些日子吗?2) The factory where / in which he worked for twenty years is closing down. 他效力了20年的那个工厂倒闭了。3) The reason why / for which he was late for school was that he didnt catch the bus. 他之所以迟到,原因
2、是没赶上公交车。4) I have read the book in which you are interested. 我读了那本你感兴趣的书。5) The man with whom I talked just now comes from Japan. 刚刚和我交谈的那个男人来自日本。6) This is the book which she is looking for. 这就是她正在找的那本书。小结归纳 when 通常放在表示时间的名词后引导定语从句,如句1); where放在表示地点的名词后引导定语从句,如句2); why经常放在reason的后面来引导定语从句,如句3); 当引导
3、定语从句时,关系副词一般可以转化为“介词 + 关系代词”,即: when / where 可转化为on / in / at等 + which, why可转化为for which(在口语中可用that或省略),这也是定语从句中的一种常见现象。 需要特别注意的是此时介词后的关系代词不能用that, 如句1)、2)、3) 另外,指代先行词的关系代词which, whom在从句中作介词宾语时,可以把 “介词 + 关系代词(which / whom)”一起 放在先行词和从句之间,如句4)、5); 但含有介词的短语动词一般不拆开,介词仍放在动词的后面,如句6)。*关系代词that和which在定语从句中充
4、当主语或宾语关系副词when/ where/ why分别在定语从句中充当时间状语, 地点状语和原因状语。 例如: This is the house where/ in which we once lived. 这是我们曾经住过的房子 (Where相当于in the house 做地点状语) This is the house which/ that they built last year. 这是他们去年建的房子 (which/ that 指代house 做built 的宾语) Ill never forget the days when/on which we stayed in Beij
5、ing. 我永远不会忘记我们一起在北京的日子 (When相当于on the days 做时间状语, on the days “在这些日子”)Ill never forget the days which we spent in Beijing.我永远不会忘记我们一起在北京的日子 (Which指代the days 做spent的宾语) That is the reason why/ for which she told a lie. 那就是她为什么撒谎的原因。 (Why相当于for the reason 做原因状语 That is the reason which was told by the
6、 boy. 那就是那个男孩说的原因。 (Which 指代the reason 做主语)注意: 确立关系代词which/that或关系副词when/where/why的方法: 看定语从句中是否缺少主语或宾语,如果缺少用which/ that; 如果不缺主语或宾语用when/where/ why. 关系副词在定语从句中不充当主语或宾语,只能充当状语。如果先行词表时间、地点、原因,关系词在句中作主语或宾语,应该用关系代词that或which。如I still remember the days that/which we spent in the small village.( 作宾语) 我还记得我们在那个小村庄度过的那些日子。 The reason that/which he gave was not reasonable.( 作宾语) 他给的那个理由不合情理。 The factory that /which we visited yesterday is far from here.(作宾语) 我们昨天参观的那家工厂离这里很远。 用关系代词,还是关系副词完全取决于从句 中的谓语动词。 及物动词后面无宾语,就必须要求用关系代词;而不及物动词则要求用关系副词。 (参考P5例句 )
