14、 little, much, anything, nothing, everything, none 等时；或者当先行词被序数词、形容词的最高级和 all, any, few, little, no, the only, the very, the last 等词修饰时，定语从句的关系代词要用 that；如果定语从句修饰两个先行词，其中一个指人，一个指物，那么定语从句的关系代词也应用 that。2.通常只用 which 的情况 当引导非限制性定语从句，指物或指代前面整个句子的内容,或放在介词后面指物时，只能用 which。I refuse to accept the blame for som
15、ething that was someone elses fault.After graduating from college, I took some time off to go travelling, which turned out to be a wise decision. 二、who，whom，whose 引导的定语从句1.如果先行词是指人的不定代词，如：anyone, anybody, everyone, everybody, someone, somebody, nobody, one, ones, those, all 等，关系代词在定语从句中作主语时用 who，作宾语
16、时用 whom/who。2.在非限制性定语从句中，关系代词指人且作主语时用 who，作宾语时用whom/who。3.在定语从句中可以作定语的关系代词只有 whose，表示物时相当于“the + 名词 + of + which“或“of + which + the + 名词“；表示人时相当于“the + 名词 + of + whom“或“of +whom + the + 名词“。Ive become good friends with several of the students in my school who I met in the English speech contest last
17、 year.The newly-built cafe, the walls of which are painted light green, is really a peaceful place for us, especially after hard work.三、where，when，why 引导的定语从句where，when，why 的意义相当于“介词+ which“。具体而言，where 相当于 “in / at + which“，when 相当于“at / in / during + which“，why 相当于“for + which“。 1.关系副词 where 引导定语从句
18、时，只能在定语从句中作地点状语，定语从句修饰的先行词必须是表示地点的名词。2.关系副词 when 引导定语从句时，只能在定语从句中作时间状语，定语从句修饰的先行词必须是表示时间的名词。3.关系副词 why 引导定语从句时，只能在定语从句中作原因状语，定语从句修饰的先行词必须是表示原因的名词。The girl arranged to have piano lessons at the training centre with her sister where she would stay for an hour.Is this the reason he explained at the mee
19、ting for his carelessness in his work? 四、“介词+关系代词“结构的用法当关系代词作介词宾语时，就出现了“介词+关系代词“的结构引导定语从句的现象。当先行词指物时用“介词+ which“， 指人时用 “介词 + whom“，且关系代词不能省略。I saw a woman running towards me in the dark. Before I could recognize who she was, she had run back in the direction from which she had come. 五、the way 后面的定语从
20、句的引导词the way 作先行词且其后定语从句的引导词在从句中作状语时引导词用 in which,that 或者省略。He made another wonderful discovery, which I think is of importance to science. 本句中的 I think 是插入语，which 引导非限制性定语从句。辨别含有插入语的定语从句正确的方法是：去掉插入语后，原句的结构仍然完整。常见的插入语有： I think（suppose, believe, imagine）, in my opinion, to tell the truth 等。速判关系代词与关系副词做题的关键是把先行词放到从句中，看它在从句中所作的成分。 1.把先行词放到从句中后,如果不需要再添词从句就是完整的，那先行词就在从句中作主语、宾语、表语或定语（表所属关系），此时应选择关系代词（who, whom, that, which, whose)。2.把先行词放到从句中后,如果需要添介词才能使从句完整，那么先行词在从句中作状语，应选择关系副词（where 作地点状语，when 作时间状语，why 作原因状语）。
