　　I、介词+which和介词+whom
　　Preposition + which and Preposition + whom
　　II、关系副词引导的定语从句
　　(Attributive Clauses Introduced by Relative Adverbs)
　　I、介词+which和介词+whom
　　“介词+关系代词”引导定语从句时，关系代词用whom（指人）、which（指物）、whose（指人或物，后紧跟名词）。即：介词+whom；介词+which；介词+whose+名词。【参考Unit3•非限制性定语从句】
　　【警示误区】选择适当的介词要根据实际情况和定语从句后面动词和介词的搭配关系。
　　1、“介词+which”在定语从句中作时间、地点、原因状语，相当于关系副词when, where, why。
　　She still remembers the day on which (=when) she won the gold medal. 她仍然记得她获得金牌的那一天。
　　By nine o’clock, all the Olympic torch bearers had reached the top of Mount Qomolangma, above which (=where) appeared a rare rainbow soon. 截止9点时，所有的奥运火炬手都到达珠峰峰顶，很快在它的上空出现了一道罕见的彩虹。
　　The reason for which (=why) she was absent was that she missed the train. 她迟到的原因是她没有赶上火车。
　　2、“介词（短语）+which/whom”在定语从句中作目的、方式状语。
　　There is a big window in my room through which I can see the railway station. 我的房间有一个大窗户，通过它我可以看见火车站。
　　3、“不定代词或数词或名词+of which/whom”在定语从句中作主语。
　　The man pulled out a gold watch, the hands of which were made of small diamonds. 那人拿出一块金表，那表的指针是用小钻石制成的。
　　Last week, only two people came to look at the house, neither of whom wanted to buy it. 上周，只有两个人来看那间房子，但是他们都不想买它。
　　4、“介词+which+不定式”，相当于一个简化的定语从句。
　　The reporter found something about which to write (=he could write). 记者找到可以写的东西了。
　　He hasn’t found a house in which to live (he can live). 他还没有找到可居住的房子。
　　5、“介词+whose”修饰后面的名词。
　　He is the very man in whose pocket I found my lost money. 他就是那个人，在他的口袋里我找到了我丢失的钱。
　　6、根据实际情况选用不同的介词。
　　We saw several natives advancing towards our party, and one of them came up to me, to whom we gave some bells and glasses. 我们看到几个人朝我们走来，其中一个人来到我们面前，我们给了他一些铃铛和眼镜。
　　Do you know the writer about whom they are talking? 你知道他们在谈论的那位作家吗？
　　【警示误区】在一些固定搭配的动词短语中，由于动词和介词不可分割，因此不能把介词置于关系代词前。
　　This is the newspaper (that/which) I’m looking for. 这正是我要找的那张报纸。
　　II、关系副词引导的定语从句
　　关系副词在定语从句中作状语。常用的关系副词有where, when, why等。
　　1、where表示地点，在定语从句中作地点状语，其先行词一般为表示地点的名词。此时可以用类似in which, on which, at which, to which等替换。
　　Potato can be grown in places where (in which) it is too cold to grow rice. 有些太冷不能种稻米的地方可以种马铃薯。
　　Mozart’s birthplace and the house where he composed “The Magic Flute” are both museums now. 莫扎特的出生地和他创作歌剧“魔笛”的房子现在都是博物馆了。
　　Ancient China was a place where states were often at war with each other. 古代中国是各诸侯国之间经常发生战争的地方。
　　【警示误区】where引导的定语从句还可以修饰表示抽象空间（地点）概念的名词，如case（情况），situation（情形），position（位置），stage（阶段；舞台），point（地步；点），activity（活动），sport（运动），atmosphere（气氛）等。
　　What are some situations where body language is the only form of communication? 在哪些情形下体态语是唯一的沟通方式？
　　We’re just trying to reach a point where both sides will sit down together and talk. 我们正在试图找到双方都能接受的条件，从而能坐在一起谈判。
　　2、when表示时间，在定语从句中作时间状语，其先行词一般为表示时间的名词。此时可用类似on which, in which, at which, during which等替换。
　　She remembered clearly that day when she’d gone exploring in the tropical forest.
　　她清楚地记得她去热带森林探险的那天。
　　The Song Dynasty was a time when there were many great philosophers. 宋朝是一个出现了许多伟大思想家的时期。
　　I shall never forget the days when I studied in Nanjing Normal University. 我永远忘不了在南师大学习的那些日子。
