the mre...“越……就越……”
(教材P64)It was exercise fr the brain；the mre I learnt f a language，the mre my brain wuld grw.这是对大脑的锻炼；我对一门语言了解得越多，我的大脑就会越强大。
[句式分析]　该句为“the＋比较级，the＋比较级”结构，意为“越……就越……”，表示后者随着前者的变化而变化。
The mre he explained，the mre cnfused I became.他越解释我就越迷惑。
(1)在“the＋比较级，the＋比较级”结构中，前一个“the＋比较级(＋主语＋谓语)”相当于条件状语从句，后一个“the＋比较级(＋主语＋谓语)”相当于主句。(2)在表示将来意义的情况下，前者常用一般现在时，后者用一般将来时。(3)如果句意明确，“the＋比较级，the＋比较级”结构常以省略形式出现。(4)“比较级＋and＋比较级”意为“越来越……”。

一、关系副词引导的限制性定语从句当先行词在定语从句中作状语，即定语从句不缺主语、宾语或者表语时，通常要用关系副词引导定语从句。常用的关系副词有when，where，why等。关系副词的指代及功能如下：
关系副词和“介词＋关系代词”引导的限制性定语从句
1．关系副词whenwhen引导定语从句时，先行词往往是表示时间的名词(如time，day，week，mnth，year等)，关系副词when在从句中作时间状语，相当于“介词in/at/n/during...＋which”结构。I will never frget the day when/n which I first saw yu.我永远不会忘记第一次见到你的日子。I'll never frget the time when/at which I was trapped in a burning huse.我永远不会忘记我被困在燃烧着的房子里的时候。
2．关系副词wherewhere引导的定语从句的先行词往往是表示地点的名词(如place，rm，huse，spt，schl，cuntry等)，关系副词where在从句中作地点状语，相当于“介词in/at/n...＋which”。The stadium where/in which the athletes wrk ut is nt far frm here.运动员们锻炼的体育馆离这里不远。After living in Paris fr fifty years he returned t the small twn where/in which he grew up as a child.在巴黎生活了50年后，他回到了儿时成长的那个小镇。
[温馨提示]　当先行词为situatin，case，stage，pint，activity，atmsphere等抽象名词，且引导词在定语从句中表示事情发生的情况、阶段等时，常用关系副词where引导。They have reached the pint where they have t separate with each ther.他们已经到了必须分手的地步。
3．关系副词whywhy引导定语从句时，先行词为reasn，关系副词why在从句中作原因状语。相当于“fr＋which”结构。D yu knw the reasn why/fr which she is under great stress?你知道她压力很大的原因吗？
[即时训练]　用适当的关系副词填空①The reasn ____ we Chinese celebrate the Dragn Bat Festival is in hnur f Qu Yuan.②I will attend a family get-tgether this Saturday _____ my brther Tim returns hme frm Shanghai.③We have entered int an age _____ dreams have the best chance f cming true.④I'd like t live in the huse ______ there is plenty f sunshine.
二、关系代词和关系副词的判断表示时间、地点及原因的名词作先行词时，定语从句可用关系代词引导，也可用关系副词引导。若关系词在定语从句中作状语，应用关系副词；若关系词在定语从句中作主语或宾语，则应用关系代词。D yu remember the days when we chatted with each ther all night？(when作时间状语)你还记得我们整夜聊天的那些日子吗？D yu remember the days that/which we spent tgether n the farm？(that或which作spent的宾语)
你还记得我们在农场一起度过的那些日子吗？I dn't knw the reasn why he didn't turn t his gd friend fr help yesterday.(why作原因状语)我不知道昨天他为什么没向他的好朋友求助。I wn't listen t the reasn that/which yu have given us.(定语从句中缺少宾语，所以用that/which，不用why)我坚决不听你给我们的那个理由。
[即时训练]　用that，which，when，where，why填空①I will never frget the days ___________ we spent tgether.②D yu remember the day _____ we first met?③The reasn ___________ he explained at the meeting was nt sund.④The reasn ____ he was late was that he missed his bus.⑤The schl _____ I studied fr nly tw years was three kilmetres away.⑥This is the huse ___________ was built by my grandfather frty years ag.
三、“介词＋关系代词”引导的限制性定语从句关系代词作介词的宾语时，为了使关系代词与先行词的关系更加紧凑，可以将从句中的介词提到关系代词前，形成“介词＋关系代词”的结构。该结构中的关系代词可用which，whm 或whse。1．介词的选用：可以遵循“一名二动三逻辑”的原则。(1)“一名”——依据与先行词搭配的具体意义而定。I'll never frget the farm n which I spent my childhd in the cuntry.我永远不会忘记我在乡村度过童年时光的那个农场。I still remember the day n which I graduated frm cllege.我仍然记得我大学毕业的那一天。
(2)“二动”——依据与定语从句中的动词或动词后的形容词的某种习惯搭配来确定。We expect yu t becme smene f whm we'll feel very prud in the future.我们期望你将来能成为我们会为之骄傲的人。This is the bk abut which we talked yesterday.这就是我们昨天谈论的那本书。(3)“三逻辑”——依据从句表达的意义和先行词的逻辑关系来确定。The clrless gas withut which we cannt live is called xygen.这种无色的、离开它我们就无法生存的气体叫作氧气。He is a man fr whm I have the greatest respect.他是我非常尊敬的人。
[温馨提示]　有些“动词＋介词”短语如lk fr，lk after，call n等，如果介词提前将会失去动词短语的意义，所以不可把介词置于关系代词前。Is this the brchure which she is lking fr?这就是她在找的那本册子吗？The babies whm the nurses are lking after are healthy.护士们在照看的婴儿都很健康。
2．“名词/数词/代词等＋介词f＋关系代词”结构。有时“介词＋关系代词”前还会有名词、数词、代词等，表示部分、整体、数量等概念。He mentined a bk the title f which I can't remember nw.他曾提到一本书，书名我现在不记得了。I saw sme trees the leaves f which were black with disease.我看到一些树因病害叶子变黑了。
[即时训练]　用“介词＋关系代词”填空①They als had a small pnd _________ they raised fish.②Nne f us knw the reasn __________ Tm didn't cme.③This is the man __________ I just shk hands.④This is the pen ___________ he ften writes article.
用适当的关系词填空There was a time 1．____ I was tired f learning English and disliked t speak English.And this was the reasn 2.____ my father frced me t jin in a 30-day training prgram in an English club befre I went t senir high schl.When I first came t the club，3._____ I met many strangers，I missed my parents very much.S I packed up my things and wanted t g hme.Frtunately，my guide teacher 4.______ name was Li Yang，cmmunicated with me face t face，frm 5.______ I gained sme useful instructins.

学习英语王乐：嗨，大家好，请问你们在学习英语时遇到的最大问题是什么？刘文：你好！我从小学就一直在学习英语。以前我的英语成绩还挺好的，但是现在我的听力有很大的麻烦。我在视频中听母语是英语的人说话时，只能听懂几个单词。我从来就没能完全搞懂过大意。有什么建议吗？
佳欣：收听英语广播节目帮助我习惯母语人士的语速。我还会复述听到的内容，以此来培养语感。有时候我甚至还给自己录音，那样一来，我可以听自己的发音，并把我的发音与广播主持人的进行比较！我最头疼的问题是如何用英语得体地表达。说“打开窗户！”很容易，可是在英语里，这样说听起来感觉很糟糕。我得考虑到我在跟谁说话，然后再决定是说“请打开窗户！”还是“请你打开窗户，好吗？”或者说句更长的“请问，您介意打开窗户吗？”
