Tapescriptpopulationpopulation意為“人口數(shù)量”，謂語動詞要用單數(shù)形式。詢問人口數(shù)量時要用“What’sthepopulationof...?”提問，而不用howmany或howmuch等提問。表示人口“多”要用large或big；表示人口“少”要用small。LanguagepointsPractice這個城市的人口是600萬。Thepopulationofthiscityissixmillion．中國的人口比美國的人口多很多。ThepopulationofChinaismuch

中國的長城共有近一萬公里，東起河北秦皇島的山海關(guān)，西到嘉峪關(guān)，這是明代修筑長城的兩個最大關(guān)口，北京境內(nèi)的長城有600余公里，比較著名的有八達嶺長城、金山嶺長城、司馬臺長城、慕田峪長城、居庸關(guān)長城和箭扣長城等。TheGreatWall

在今天的長城游中，大家盡管問我任何問題，不要拘束。

feelfree是英語口語中一個常用表達。若有人讓你feelfreetodosomething,就是讓你無需拘束，只管按照自己的意愿去做某事。e.g.A:CanIuseyourbathroom?我可以用一下你的衛(wèi)生間嗎？B:Yes,feelfree.可以，請隨意。Languagepoints2.AsfarasIknow,therearenoman-madeobjectsasbigasthis.

據(jù)我所知，再沒有像它這樣大的人造物體了。asfarasIknow是一個固定的表達方式，還可以說sofarasIknow，意思是“據(jù)我所知”。例如：AsfarasIknow,Jack’sgottwinsisters.就我所知，杰克有一對孿生姐妹。They’renotcomingtoday,sofarasIknow.他們今天不來了—就我所知是這樣的。asfaras也可表示“遠至”(在否定句中也可用sofaras)。Practice我們坐火車到北京，然后轉(zhuǎn)乘公共汽車。WewillgobytrainasfarasBeijing,andthantakeabus.我們不如其他人走得遠。Wedidn’tgoas/sofarastheothers.man-made為合成形容詞，意為“人造的”。英語中像這樣與-made復(fù)合而成的形容詞還有：handmade(手工制作的)、homemade(家庭制作的)、machine-made(機制的)、tailor-made(量體定制的；特制的；定做的)等，用以描述產(chǎn)品的生產(chǎn)或制造手段、特點等，甚至還有像self-made(自學(xué)而成的；自我奮斗而成的；天然形成的)可以用來描述人。Practice面包和糕點都是自家做的。Thebreadandpastryarehomemade.這個電影角色是專為那位男演員量身設(shè)計的。Thismovierolewastailor-madeforthatactor.3.theMingGreatWall明長城“明長城”是指明朝時期為了防御北方游牧民族的騷擾，歷時一百多年在北部地區(qū)修筑的軍事防御工程。這段長城東起遼寧虎山，西至甘肅嘉峪關(guān)，從東向西橫貫多個省、直轄市、自治區(qū)，全長約8850千米，是現(xiàn)存歷代長城遺跡中最完整、最堅固的。Review課時重點回顧What’sthepopulationof...?Itis…metershigh(long,wide…).much,even,alittle,still,alot,less+形容詞比較級asfarasIknow…as/sofarasIcanremember/Icantell/Icanseeasfaras遠至合成詞man-madeChoosethebestanswer.1.Mybrotheris___moreoutgoingthanme.A.manyB.littleC.much2.October12thwasoneof______daysin2005.Shenzhou-VIwaslaunched(發(fā)射)successfully.A.excitingB.moreexcitingC.themostexciting3.Whichcityis______,Beijing,ShanghaiorFuzhou?A.beautifulB.morebeautifulC.themostbeautiful4._____childrenthereareinafamily,____theirlifewillbe.A.Theless,thebetterB.Fewer,richerC.Thefewer,thebetter5.Mobilephonesareverypopularnowandtheyare______thanbefore.A.cheapB.cheaperC.thecheapest6.Inourcity,it’s_____inJuly,butit’seven___inAugust.A.hotter,hottestB.hot,hotC.hot,hotter7.Ofthetwoskirts,thepinkoneis______.A.thenicestB.thenicerC.nicer8.Jack’shandwritingisas____asMike’s.A.goodB.betterC.best9.Wecandotheworkbetterwith____moneyand______people.A.little,fewB.less,fewerC.fewer,less10.JimisthetalleststudentinourclassandTomisthesecond______one.A.tallB.tallerC.tallest

在喜馬拉雅山脈之中，海拔在7000米以上的高峰有50多座，8000米以上的有16座，著名的有南峰、希夏邦馬峰、干城章嘉峰?！跋柴R拉雅”在藏語中就是“冰雪之鄉(xiāng)”的意思。這里終年冰雪覆蓋，一座座冰峰如倚天的寶劍，一條條冰川像蜿蜒的銀蛇。其中最為高聳的則是位于中國和尼泊爾邊界上的珠穆朗瑪峰，它以高達8844.43米的高度，是世界最高峰。

珠穆朗瑪峰(Qomolangma)，簡稱珠峰，又譯作圣母峰，尼泊爾稱為薩加馬塔峰，也叫“埃非勒斯峰”（Everest），位于中華人民共和國和尼泊爾交界的喜馬拉雅山脈之上，終年積雪。高度8844.43米，為世界第一高峰，中國最美的、令人震撼的十大名山之一。

珠峰所在的喜馬拉雅山地區(qū)原是一片海洋，在漫長的地質(zhì)年代，從陸地上沖刷來大量的碎石和泥沙，堆積在喜馬拉雅山地區(qū)，形成了這里厚達3萬米以上的海相沉積巖層。以后，由于強烈的造山運動，使喜馬拉雅山地區(qū)受擠壓而猛烈抬升，據(jù)測算，平均每一萬年大約升高20～30米，直至如今，喜馬拉雅山區(qū)仍處在不斷上升之中。1953年5月29日，34歲來自新西蘭的登山家埃德蒙·希拉里（EdmundHillary）作為英國登山隊隊員與39歲的尼泊爾向?qū)Уぴ觥ぶZ爾蓋TenzingNorgay一起沿東南山脊路線登上珠穆朗瑪峰，是紀(jì)錄上第一個登頂成功的登山隊伍。1960年5月25日，中華人民共和國人首次登上珠穆朗瑪峰。他們是王富洲、貢布（藏族）、屈銀華。此次攀登，也是首次從北坡攀登成功。1960年，我國首次登上地球之顛的3名英雄。1975年5月16日，日本人田部井淳子從東南山脊路線登上了珠穆朗瑪峰，是世界登山運動史上第一個踏上地球之巔的女性。1975年5月27日，中國登山隊的藏族女隊員潘多成為世界上第一個從北坡登上珠穆朗瑪峰的女性。2008年5月8日，中國登山隊圣火傳遞珠穆朗瑪峰突擊隊員，成功地把圣火從8300米突擊隊營地傳遞到了珠穆朗瑪峰峰頂，創(chuàng)造了人類奧運歷史上的奇跡。自讀文章，在書中劃出重點、疑點后，翻譯下列短語。先獨立完成，后小組商議。1.最危險的山峰

相當(dāng)于makeourdreamscometrue其中動詞achieve表示“（通過努力）實現(xiàn)；取得；獲??；達到（夢想、成績、成功、目的)”等。例如：Heachievedgreatsuccessinashorttime.他用很短的時間取得了極大的成功。LinTaoachievedverygoodexamresults.林濤考試取得了很好的成績。5.Whydosomanypeopletrytoclimbthismountaineventhoughitisdangerous?eventhough用作從屬連詞，意為“即使；盡管”，相當(dāng)于evenif，引導(dǎo)讓步狀語從句，一般不與并列連詞but連用。如：Mr.Wangwillcomeontimeeventhough
