[我的发现](1)关系副词_______在定语从句中作时间状语(如句_____)；关系副词________在定语从句中作地点状语(如句_____)；关系副词______在定语从句中作原因状语(如句_____)。(2)在 “介词＋which/whm” 引导的定语从句中，________用于指代物(如句_____)；_______用于指代人(如句_____)。
关系副词和 “介词＋关系代词” 引导的定语从句语法点拨一、关系副词引导的定语从句引导定语从句的关系副词包括when, where, why，一般代替(介词＋)先行词在从句中作状语，表示时间、地点、原因。其具体用法见下表：
1．when的用法when指时间，在定语从句中作时间状语。它的先行词通常为time，day，mrning，night，week，year等表示时间的名词。There was a time when a deep blue sky, the sng f the birds，mnlight and flwers culd never have kept me spellbund. 曾有一段时间，湛蓝的天空、鸟儿的歌唱、月光和鲜花从未令我心迷神往过。We will put ff the picnic in the park until next week, when the weather may be better. 我们将把在公园举行的野餐推迟到下周，那时天气可能比现在好。
先行词是表示时间的词时，关系词是否用when，还需要判断关系词在从句中所作的成分。We still remember the days when we spent ur hliday tgether. 我们仍然记得我们在一起度假的那些日子。(when在从句中作时间状语)We still remember the days (that/which) we spent tgether. 我们仍然记得我们一起度过的那些日子。(that/which在从句中作宾语)
2．where的用法where指地点，在定语从句中作地点状语。它的先行词通常为place，spt，street，huse，rm，city，twn，cuntry等表示地点的名词或pint(地步)，case(情况)，situatin(情形)，psitin(位置)，stage(阶段)等表示抽象地点的名词。
The mvie is set in a small twn where the nly mvie theatre is preparing t clse dwn. 这部电影以一座小镇为背景，这座小镇唯一的电影院即将倒闭。They went t the Ryal Theatre, where they saw an interesting play. 他们去了皇家剧院，在那里看了一场有趣的戏剧。What are sme situatins where bdy language is the nly frm f cmmunicatin?在哪些情况下身体语言是唯一的沟通方式？
先行词是表示地点的词时，关系词是否用where，还需要判断关系词在从句中所作的成分。This is the huse where we visited the famus writer last year. 去年我们就是在这所房子里拜访了那位著名作家。(where在从句中作地点状语)The huse(that/which) we visited last year is ver 500 years ld. 我们去年参观的那个房子有500多年的历史了。(that/which在从句中作宾语)
3．why的用法why指原因或理由，它的先行词只有reasn，why在限制性定语从句中作原因状语。I have cme arund t explain the reasn why(＝fr which) I was absent frm the meeting. 我来是为了解释我当时没有到会的原因的。
先行词是reasn时，关系词是否用why，还需要判断关系词在从句中所作的成分。This is the reasn why he was late. 这就是他迟到的原因。(why在从句中原因作状语)Please tell me the reasn (that/which) he explained t yu. 请告诉我他向你解释的原因。(that/which在从句中作宾语)
4．the way作先行词首先要确定关系词在定语从句中作什么成分。(1)如果关系词在定语从句中作主语、宾语或表语，则用关系代词that或which。The way (that/which) he thught f t slve the prblem was nt practical. 他所想到的解决这个问题的方法不切实际。
(2)如果关系词在定语从句中作状语，则用关系词in which，that或省略。This is the way (that/in which) he learns English. 这就是他学习英语的方法。
选词填空：(that/which/when/where/why)①I will never frget the days _______ we stayed tgether. ②The reasn ______________ he explained at the meeting was nt sund. ③The reasn ______ he was late was that he missed his train. ④Keep the bk in a place ________ yu can find it easily. ⑤This is the huse ______________ was built by my grandfather frty years ag.
that/which　
which/that　
二、“介词＋关系代词” 引导的定语从句1．在这种结构中，若关系代词指人，只能用whm；若关系代词指物，只能用which。It was in 1952 and Mandela was the black lawyer t whm I went fr advice. 那是在1952年，曼德拉当时是一位黑人律师，我向他寻求建议。I’ll never frget the day n which (＝when) I first met yu. 我永远不会忘记初次见你的那一天。
This is the twn in which (＝where) Shakespeare was brn. 这就是莎士比亚出生的城镇。I frgt the exact place t which (＝where) I had paid a visit. 我忘记了已经参观过的确切地点。There’s n reasn fr which (＝why) we can betray ur friends. 我们没有理由背叛朋友。I’d like yu t explain the reasn fr which(＝why) yu were absent. 我想让你解释一下你没来的原因。
“名词/代词/数词/最高级＋f＋关系代词” 结构比如：nne/sme/several/a few/many/mre/mst/tw/the biggest f which/whm等。The jurney arund the wrld wuld take the sailr nine mnths, the sailing time f which (＝f which the sailing time) was 226 days. 环游世界花费了水手们九个月的时间，其中航行时间是226天。
Here are the questins, nne f which (＝f which nne) I thught are difficult fr yu. 就是这些问题，我认为对你来说没有一个是困难的。Present at the meeting were almst experts n AI, mst f whm (＝f whm mst) were male. 出席会议的大都是人工智能方面的专家，其中大部分是男性。
2．关系代词前介词的选用(1)依据定语从句中动词的习惯搭配来确定。Clse friends are thse t whm yu feel s clse that it is hard t imagine life withut them. 密友就是那些你感到如此亲近的人，以至于你无法想象没有他们的生活。(feel clse t)Charity is the cause t which he is devted. 慈善是他挚爱的事业。(be devted t)
(2)依据与先行词的搭配来确定。This is the farm n which he wrks. 这就是他工作的农场。(n the farm)(3)根据所表达的意思来确定。The clurless gas withut which we cannt live is called xygen. 这种无色的气体就是氧气，离开了它我们不能生存。
有些 “动词(＋名词)＋介词” 的固定搭配，如lk fr，lk after，call n，take care f等，不能把介词提到关系代词前。My yungest brther, after whm I have t lk, is very naughty. (×)My yungest brther, whm I have t lk after, is very naughty. (√)
用“介词＋关系代词”填空①Many yung peple，mst _________ were well-educated, headed fr remte regins t chase their dreams. ②Scientists have many advanced theries abut why human beings cry tears，nne __________ has been prved. ③D yu remember the day __________ yu jined ur club?④There is a big windw _______________ I can see the railway statin.

with which　
三、使用定语从句应该注意的问题1．定语从句中的主谓一致问题。当引导定语从句的关系代词在从句中作主语时，定语从句中的谓语动词的数应与先行词保持一致。下面是定语从句在实际运用中需要注意的几个主谓一致的问题：
(1)I作先行词时，定语从句中谓语动词应该与I保持一致。I, wh am yur teacher, will try t slve all kinds f questins. 我作为你的老师，会尽力解决各种各样的问题。(2)当关系代词as或which引导非限制性定语从句，指代整个主句，且作从句的主语时，从句的谓语动词用单数形式。Great changes have taken place in China, as is knwn t all. 众所周知，中国已经发生了天翻地覆的变化。
(3)当 “ne f＋the(＋形容词最高级)＋复数名词” 位于关系词前时，定语从句的先行词是复数名词，从句的谓语动词要用复数形式。The Summer Palace is ne f the wrld-famus places f interest that draw lts f visitrs. 颐和园是吸引着大批游客的世界名胜之一。The Lrd f the Rings is ne f the mst wnderful mvies that have been prduced in Hllywd. 《指环王》是好莱坞制作的最精彩的电影之一。
当“the nly ne f＋the(＋形容词最高级)＋复数名词” 位于关系词前时，定语从句的先行词是the nly ne，从句的谓语动词要用单数形式。This is the nly ne f the sngs in the album that is sung in English. 这是这张专辑中唯一一首英文歌曲。Titanic is the nly ne f the mst wnderful mvies that has been prduced in Hllywd. 在这些最精彩的电影中，《泰坦尼克号》是唯一一部好莱坞制作的影片。
2．frm where，since/until/by when也可以引导定语从句。He std n tp f the hill, frm where he culd see the Yangtze River. 他站在山顶上，从那里他能看到长江。(frm where＝frm which place)The bk was written in 1946, since when the educatin system has seen great changes. 这本书著于1946年，从那时起教育体制发生了重大变化。(since/ until/by when＝since/until/by which time)
