中国的长城共有近一万公里，东起河北秦皇岛的山海关，西到嘉峪关，这是明代修筑长城的两个最大关口，北京境内的长城有600余公里，比较著名的有八达岭长城、金山岭长城、司马台长城、慕田峪长城、居庸关长城和箭扣长城等。TheGreatWall

在今天的长城游中，大家尽管问我任何问题，不要拘束。

feelfree是英语口语中一个常用表达。若有人让你feelfreetodosomething,就是让你无需拘束，只管按照自己的意愿去做某事。e.g.A:CanIuseyourbathroom?我可以用一下你的卫生间吗？B:Yes,feelfree.可以，请随意。Languagepoints2.AsfarasIknow,therearenoman-madeobjectsasbigasthis.

据我所知，再没有像它这样大的人造物体了。asfarasIknow是一个固定的表达方式，还可以说sofarasIknow，意思是“据我所知”。例如：AsfarasIknow,Jack’sgottwinsisters.就我所知，杰克有一对孪生姐妹。They’renotcomingtoday,sofarasIknow.他们今天不来了—就我所知是这样的。asfaras也可表示“远至”(在否定句中也可用sofaras)。Practice我们坐火车到北京，然后转乘公共汽车。WewillgobytrainasfarasBeijing,andthantakeabus.我们不如其他人走得远。Wedidn’tgoas/sofarastheothers.man-made为合成形容词，意为“人造的”。英语中像这样与-made复合而成的形容词还有：handmade(手工制作的)、homemade(家庭制作的)、machine-made(机制的)、tailor-made(量体定制的；特制的；定做的)等，用以描述产品的生产或制造手段、特点等，甚至还有像self-made(自学而成的；自我奋斗而成的；天然形成的)可以用来描述人。Practice面包和糕点都是自家做的。Thebreadandpastryarehomemade.这个电影角色是专为那位男演员量身设计的。Thismovierolewastailor-madeforthatactor.3.theMingGreatWall明长城“明长城”是指明朝时期为了防御北方游牧民族的骚扰，历时一百多年在北部地区修筑的军事防御工程。这段长城东起辽宁虎山，西至甘肃嘉峪关，从东向西横贯多个省、直辖市、自治区，全长约8850千米，是现存历代长城遗迹中最完整、最坚固的。Review课时重点回顾What’sthepopulationof...?Itis…metershigh(long,wide…).much,even,alittle,still,alot,less+形容词比较级asfarasIknow…as/sofarasIcanremember/Icantell/Icanseeasfaras远至合成词man-madeChoosethebestanswer.1.Mybrotheris___moreoutgoingthanme.A.manyB.littleC.much2.October12thwasoneof______daysin2005.Shenzhou-VIwaslaunched(发射)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

在喜马拉雅山脉之中，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、希夏邦马峰、干城章嘉峰。“喜马拉雅”在藏语中就是“冰雪之乡”的意思。这里终年冰雪覆盖，一座座冰峰如倚天的宝剑，一条条冰川像蜿蜒的银蛇。其中最为高耸的则是位于中国和尼泊尔边界上的珠穆朗玛峰，它以高达8844.43米的高度，是世界最高峰。

珠穆朗玛峰(Qomolangma)，简称珠峰，又译作圣母峰，尼泊尔称为萨加马塔峰，也叫“埃非勒斯峰”（Everest），位于中华人民共和国和尼泊尔交界的喜马拉雅山脉之上，终年积雪。高度8844.43米，为世界第一高峰，中国最美的、令人震撼的十大名山之一。

珠峰所在的喜马拉雅山地区原是一片海洋，在漫长的地质年代，从陆地上冲刷来大量的碎石和泥沙，堆积在喜马拉雅山地区，形成了这里厚达3万米以上的海相沉积岩层。以后，由于强烈的造山运动，使喜马拉雅山地区受挤压而猛烈抬升，据测算，平均每一万年大约升高20～30米，直至如今，喜马拉雅山区仍处在不断上升之中。1953年5月29日，34岁来自新西兰的登山家埃德蒙·希拉里（EdmundHillary）作为英国登山队队员与39岁的尼泊尔向导丹增·诺尔盖TenzingNorgay一起沿东南山脊路线登上珠穆朗玛峰，是纪录上第一个登顶成功的登山队伍。1960年5月25日，中华人民共和国人首次登上珠穆朗玛峰。他们是王富洲、贡布（藏族）、屈银华。此次攀登，也是首次从北坡攀登成功。1960年，我国首次登上地球之颠的3名英雄。1975年5月16日，日本人田部井淳子从东南山脊路线登上了珠穆朗玛峰，是世界登山运动史上第一个踏上地球之巅的女性。1975年5月27日，中国登山队的藏族女队员潘多成为世界上第一个从北坡登上珠穆朗玛峰的女性。2008年5月8日，中国登山队圣火传递珠穆朗玛峰突击队员，成功地把圣火从8300米突击队营地传递到了珠穆朗玛峰峰顶，创造了人类奥运历史上的奇迹。自读文章，在书中划出重点、疑点后，翻译下列短语。先独立完成，后小组商议。1.最危险的山峰

includefreezingweatherconditionsandheavystorms.更加严峻的困难包括极冷的天气状况和巨大的风暴。 1）difficulty既可作可数名词也可作不可数名词，在此用作可数名词。作可数名词时,difficulty通常用作复数，表示具体概念，即：各种各样的“困难；难题；难事”。例如：Peoplelearninganewlanguagemayfacesomedifficulties.人们学习一门新的语言时可能会遇到一些困难。Ifyouhaveanydifficulties,youcancallmeforhelp.如果你遇到任何困难，给我打电话求助好了。 作不可数名词时，difficulty可译作“困难；艰难；辛苦；费劲”，例如：Hehadgreatdifficultyinfindinganewjob.

他找新的工作费了很大劲。 .Wefoundthehousewithoutdifficulty.

我们轻而易举地找到广那座房子。2）include表示“包括；包含”，是一个及物动词。例如：Doesyourpriceofthebikeincludethislight?你们的车价包含这盏车灯吗？ 3.Itisalsoveryhardtotakeinairasyougetnearthetop.

相当于makeourdreamscometrue其中动词achieve表示“（通过努力）实现；取得；获取；达到（梦想、成绩、成功、目的)”等。例如：Heachievedgreatsuccessinashorttime.他用很短的时间取得了极大的成功。LinTaoachievedverygoodexamresults.林涛考试取得了很好的成绩。5.Whydosomanypeopletrytoclimbthismountaineventhoughitisdangerous?eventhough用作从属连词，意为“即使；尽管”，相当于evenif，引导让步状语从句，一般不与并列连词but连用。如：Mr.Wangwillcomeontimeeventhough
