Unit 5 Nelson Mandela — a modern hero 纳尔逊?曼德拉——一位当代英雄 Learning about Language;关系副词和“介词+which/whom”引导的定语从句 定语从句是高考的热点，其中关系副词where, when，why和“介词+which/whom”引导的定语从句的考查是重中之重，在学习时要注意关系副词where, when，why和“介词+which/whom”的用法及它们之间的关系。;观察下列句子的结构： ①The time when I first met Nelson Mandela was a very difficult period of my life. ②The last thirty years have seen the greatest number of laws stopping our rights and progress，until today we have reached a stage where we have almost no rights at all. ③It was in 1952 and Mandela was a black lawyer to whom I went for advice. ;④The parts of towns in which they had to live were decided by white people. 结论：（1）①、②句是关系副词when和where引导的定语从句，它们所修饰的先行词为表______和_____的名词。 （2）③、④句为“介词+whom/which”引导的定语从句。当先行词表示地点或指物时，用“_____________”；而当先行词指人时，用“_____________”。; 一、关系副词的指代及功能; ＊In August 1905, Sun Yat-sen founded an organization in Tokyo where he was living. 1905年8月，孙中山在他当时居住的东京创办了一个组织。（where引导定语从句，先行词表示地点） ＊ We will never forget the days when we held the World Expo in Shanghai. 我们永远都不会忘记我们在上海举办世博会的日子。（when引导定语从句，先行词表示时间）; ＊ Can you explain the reason why you don’t help him? 你能解释一下你不帮助他的理由吗？（why引导定语从句，先行词表示原因） 【名师点津】关系副词选择两点注意： (1)当先行词分别为表示时间、地点或原因的名词，且从句中需要相应的时间、地点或原因作状语时，则用关系副词。 (2)why引导定语从句时，先行词一般为reason。; 二、关系副词where, when, why在定语从句中分别作地点、时间、原因状语，且可根据其在句中的搭配关系，转换成“介词+关系代词which/whom”的结构。 ＊The Chinese government recently made a White Paper, in which（=where） it said that peaceful development is a good choice. 中国政府最近发表了一份白皮书，白皮书中说和平发展是一个非常好的选择。（in which引导定语从句，which指a White Paper；in which可以换成where）; ＊The day will come on which（=when） we will win the final victory. 我们赢得最后胜利的日子终将到来。（on which引导定语从句，which指代the day；on which可以换成when） ＊Do you know the reason for which（= why） he was so happy? 你知道他为什么那么高兴吗？(引导定语从句，which指代先行词the reason; 此处for which可以换成why);【名师点津】 确定介词三原则 一看先行词：The company in which Peter is working is very famous. 彼得正在工作的公司非常出名。（在公司里
