“介词＋关系代词”引导的定语从句一、关系代词的确定 “介词＋关系代词”引导的定语从句中，先行词指人时关系代词用whm，不可用wh/that；先行词指物时关系代词用which，不能用that。但如果介词后置，则不受这种限制。
D yu knw the girl t whm ur teacher is talking? ＝D yu knw the girl (wh/whm/that) ur teacher is talking t?你认识我们老师正在谈话的那个女孩子吗？The schl in which my friend nce studied is very famus．＝The schl (that/which) my friend nce studied in is very famus．我的朋友曾经就读的那所学校很有名。
[即时训练1]　用适当的关系代词填空 ①Is she the girl frm _____ yu brrwed the dress yesterday evening?②The man _______________ I share the rm with is a yung teacher frm cllege．③Can yu tell me the reasn fr _____ yu didn't cme t her birthday party?④Wind pwer is an ancient surce f energy ___________ we may return t in the near future．
wh/whm/that
二、介词的选择 介词的选择可以总结为：“一先、二动、三意义、四特殊”。1．一先，即先看先行词，从先行词入手。介词往往和先行词构成固定搭配。(比如先行词表示时间，常和n，in，by搭配；表示地点，常与n，in，at搭配；表示原因，与fr搭配；表示方式，常与in，by，with搭配)D yu still remember the day n which we met fr the first time?你还记得我们第一次见面的那一天吗？(n the day)I dn't knw the reasn fr which he was late fr schl．我不知道他为何上学迟到。(fr the reasn)
2．二动，即看从句中的谓语动词。根据从句中谓语动词与介词的固定搭配选择合适的介词。Is this the car fr which yu paid a high price?这就是你花高价买的那辆汽车吗？(pay fr)This is the cmputer n which I spent 3，000 yuan．这就是我花3 000元买的电脑。(spend mney n sth．)
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。My cmputer，withut which I can't surf the Internet，brke dwn yesterday．昨天我的电脑坏了，没有它我无法上网。4．四特殊：介词f 常用于表示部分与整体的关系或所属关系。In ur class there are 54 students，half f whm wear glasses．我们班有54名学生，其中一半戴眼镜。
[即时训练2]　用适当的介词填空①I will never frget the day ____ which I was admitted t a famus university．②My father is the first persn __ whm I will turn fr help when I meet difficulties．③Wuld yu be kind enugh t help the by ___ whm Chinese is really hard t learn?④Students shuld take an active part in the cmmunity activities ____ which they can gain scial experience．
三、“介词＋关系代词”的几点注意事项1．“介词＋关系代词”在定语从句中分别可作时间、地点、原因状语，代替相应的关系副词when，where和why。This is the huse in which(＝where) I lived tw years ag．这就是两年前我居住的那个房子。The reasn fr which(＝why) he refused the invitatin is nt clear．他拒绝这个邀请的原因尚不清楚。We'd better fix a date n which(＝when) we will practice spken English next week．我们最好定个日期在下周练习一下英语口语。
2．有些固定的短语动词在定语从句中作谓语时，该短语动词的介词一般不提至关系代词前，常见的此类短语动词有listen t，lk fr，depend n，take care f 等。[误]This is the watch fr which I am lking．[正]This is the watch (which/that) I am lking fr．这就是我正在找的那块手表。
3．“代词/数词＋f＋which/whm”引导的定语从句。The ld man has tw sns，bth f whm are lawyers．这位老人有两个儿子，他们都是律师。4．“the＋名词＋f＋which/whm”引导的定语从句。Lk at the building，the rf f which is white．看那座楼房，它的屋顶是白色的。
5．“the＋形容词比较级/最高级＋f＋which/whm”引导的定语从句。There are tw buildings，the larger f which stands nearly a hundred feet high．那里有两座建筑物，较大的那座几乎有100英尺高。

A Lve f Gardening“If yu lk the right way，yu can see that the whle wrld is a garden．[1]” These wrds cme frm the authr f the bk The Secret Garden，first published① in 1911[2]．At that time，nly the very rich in Britain had gardens．Very sn after this，hmes with gardens began t be built．This is what started the British lve f gardening[3]! Tday，millins f ② Brits like t say that they have “green fingers③”，with arund half the ppulatin spending their free time gardening④[4]．
[1] if引导条件状语从句；that引导的是宾语从句，作see的宾语。[2]过去分词短语作后置定语，修饰The Secret Garden。[3]what引导的是表语从句。[4]“with＋宾语＋动词-ing形式”的with复合结构在句中作状语。
Fr many peple in the UK，their garden is their wn private wrld．Each spring，children plant sunflwers⑤ and wait t see which ne is the tallest[5]．Expert⑥ gardeners⑦ knw just the right crner⑧ fr rses，and thers spend hurs trying t grw perfect vegetables t enter⑨ int cmpetitins．And while many Brits like nthing better than spending their Sunday cutting the grass[6]，sme are happy just t sit under the branches⑩ f the trees and enjy the beauty f the wrld arund them．
[5]which引导宾语从句，作see的宾语。[6]while意为“尽管，虽然”，引导让步状语从句，其中nthing better than为“否定词＋比较级”表示最高级含义。
But in cities，limited⑪ space has led t⑫ peple lking fr new slutins．Thse withut utside space can rent⑬ small pieces f land n which t grw things[7]．Tday，there are ver 4，000 peple in Lndn waiting fr such pieces f land[8]．One recent idea has been t turn rftps⑭ and walls int private gardens．These gardens have helped make the cities greener[9] and imprve air quality．
[7]“介词＋关系代词＋不定式”作定语相当于定语从句n which they can grw things，修饰其前的land。[8]动词-ing形式短语作后置定语，修饰ver 4，000 peple。[9]“make＋宾语＋宾补”结构。
As well as⑮ being gd fr⑯ the envirnment，gardening is als gd fr the sul．What ther free-time activity⑰ allws yu t⑱ be at ne with⑲ nature and create mre beautiful living things? And if yu're in any dubt⑳ abut this[10]，take a mment㉑ t reflect n㉒ this line㉓ frm The Secret Garden: “Where yu tend㉔ a thistle㉕ cannt grw．”
[10]if引导的是条件状语从句。
热爱园艺“如果从合适的角度去欣赏，你会发现整个世界就是一个花园。”《秘密花园》的作者曾这样说。这本书1911年首次出版，在当时的英国，只有富豪才拥有花园。不久之后，人们开始建造带有花园的房子，英国人对园艺的热爱就此开始！今天，数以百万的英国人喜欢说他们有“绿手指(意为擅长园艺)”，约有一半的英国人都把空闲时间用在打理花园上。
对于许多英国人来说，花园就是他们的私密世界。每年春天，孩子们种下向日葵，满怀期待地看谁种的长得最高。高明的园丁对于花园里哪个角落最合适种玫瑰都了如指掌，其他人则花费大量时间力图种出最完美的蔬菜参加竞赛。虽然许多英国人认为锄草是周日最棒的活动，但也有的人只要能坐在树下享受周围世界的美丽就心满意足了。但在城市里，有限的空间促使人们寻找新的解决方案。住宅外部没有空间的居民可以租用小块土地种植作物。现如今，伦敦有四千多人在等待租用这样的土地。近期的一个理念是将屋顶和墙壁改造为私人花园。这些花园可以增加城市绿化面积、改善空气质量。
