Section Ⅲ　Using language—Grammar 定语从句(3) [对应学生用书P165] [观察] 1．(教材P62)These terraces were built by the local Zhuang and Yao people, to whom Guangxi is home. 2．(教材P63)But perhaps what is most significant is the way in which people have worked in harmony with nature to make these terraces and grow rice. 3．(教材P63)This forms clouds from which rain falls down onto the mountain terraces once again. 4．(教材P63)These terraces also provide a perfect environment for birds and fish, some of which feed on insects that can harm the rice crops. 5．(教材P63)Although modern technology could help produce more crops, these terraces still mean a lot to the local people for whom traditions hold much value. [归纳] 1．句1、句5中，定语从句由介词加关系代词whom引导，一般先行词为表示人的名词。 2．句2、句3、句4中，定语从句由介词加关系代词which引导，一般先行词为表示物的名词。 [对应学生用书P165] 一、“介词＋关系代词”引导的定语从句 “介词＋关系代词”引导的定语从句 介词后关系代词的选用 先行词指人时用whom 先行词指物时用which 关系代词前介词的选用 根据短语的搭配习惯确定 根据上下文的逻辑关系确定 “代词/数词＋of which/whom”引导的定语从句 the way作先行词时定语从句的引导词 1．在“介词＋关系代词”引导的定语从句中，关系代词只可用whom或which，不可用that或who。 2．当先行词指物时，介词后的关系代词用which；当先行词指人时，介词后的关系代词用whom。 3．介词后的关系代词不能省略。 Do you remember the day on which you joined our club? 还记得你加入我们俱乐部的那一天吗？ In the dark street, there wasn't a single person to whom she could turn for help. 在漆黑的大街上，她没有一个人可以求助。 The story about which I heard yesterday was not true. 我昨天听到的那个故事不是真的。 Alec asked the policeman with whom he worked to contact him whenever there was an accident. 亚历克要求和他一起工作的警察无论什么时候有事故发生都要联系他。 [即学即练]　单句语法填空 ①The woman with whom I went is my aunt. ②This was a time during which there were still slaves in the USA. ③She likes to use words of which the meaning is clear to him. ④China has a lot of rivers，the longest of which is Yangtze River. 介词的选择总体上可以归结为两点：一是根据短语的搭配习惯确定，二是根据上下文的逻辑关系确定。具体可以总结为：“一先、二动、三意义、四特殊”。 1．一先，即看先行词。介词往往和先行词构成固定搭配。(比如与时间搭配常用on, in, by；与地点搭配常用on, in, at；与原因搭配用for；与方式搭配用in, by, with等)。 2．二动，即看从句中的谓语动词。根据从句中谓语动词的搭配选择合适的介词。 3．三意义：通过判断主句表达的全部意义来确定合适的介词(即根据上下文的逻辑关系确定介词)。 4．四特殊：介词of 常用于“表示部分的词语＋of＋关系代词”结构。表示部分的词语常见的有：不定代
