即加拿大是地球上最北端的国家之一；第二个含义是指横贯加拿大东西部的一列火车的名字。.落基山脉（theRockyMountains）包含的各条山脉从加拿大亚伯达省北部和不列颠哥伦比亚省向南延伸，经美国西南部至墨西哥边境，全长约4500公里。这里有终年积雪的山峰、茂密的针叶森林、宽广的山谷、清澈的溪流、开阔的天空和丰富的矿藏资源。.大西部赛马会(theCalgaryStampede)每年七月上旬在卡尔加里举行，为期10天。主要内容是举行牛仔竞技表演，项目有骑牛、绳技、骑光背马等。此外还有各种演出、游行、燃放烟火等。大西部赛马会号称“地球上最盛大的表演" (TheGreatestOutdoorShowonEarth)。.五大湖(theGreatLakes)总面积达24.5万平方公里，有北美洲地中海之称。五大湖按大小分别为苏必利尔湖、休伦湖、密歇根湖、伊利湖和安大略湖。五大湖对周围地区气候有很大的缓和作用，湖水在暖月吸收大量热气，然后在冷月释放到大气中去。ATRIPON“THETRUENORTHLiDaiyuandhercousinLiuQianwereonatripto°Canadatovisittheircousinsin②③MontrealontheAtlanticcoast.Ratherthantaketheaeroplanealltheway,theydecidedtoflytoVancouverandthentakethetrainfromwesttoeastacrossCanada.Thethoughtthattheycouldcross.the.whole,continent④wasexciting.♦flyto...Canada与take...alltheway是ratherthan连接的两个并列成分。♦thattheycouldcrossthewholecontinent是that引导的同位语从句，解释说明thought的具体内容。Theirfriend,DannyLin,waswaitingattheairport.Hewasgoingtotakethemandtheirbaggage⑤tocatch“TheTrueNorth”,thecross-Canadatrain.Onthewaytothestation,hechatted⑥abouttheirtrip."You'regoingtoseesomegreatscenery⑦.Going.eastward.⑧，you'llpassmountainsandthousandsoflakesandforests,aswellaswideriversandlargecities.SomepeoplehavetheideathatyoucancrossCanadainlessthanfivedays,buttheyforgetthefactthatCanadais5,500kilometresfromcoasttocoast.HereinVancouver,you'reinCanada'swarmest.⑨part.PeoplesayitisCanadasmostbeautifulcity,surroundedbymountainsandthePacificOcean.SkiingintheRockyMountainsandsailinginthe

她们不想一路乘飞机，而决定先飞到温哥华，再从西海岸乘火车横穿加拿大到达东海岸。她们要横贯整个大陆的想法很是令人兴奋的。她们的朋友林丹尼正在机场等候她们。 他要带着她们和她们的行李去乘坐横越加拿大的“真北方”号列车。在去火车站的路上，他聊起了她们的旅程。 “你们将会看到一些美丽的风景。一路向东行，你们会经过一座座山脉、上千个湖泊、森林，还有宽阔的河流和许多大城市。有些人认为在不到5天的时间里就能穿越加拿大， 但是他们忘记了这样一个事实： 加拿大从东海岸到西海岸共有5500千米。这儿，温哥华， 是加拿大最温暖的地方。据说，它（温哥华）是加拿大最美丽的城市，被群山和太平洋环绕着。 落基山脉可以滑雪，海港供你扬帆，这些使得温哥华成为加拿大最受欢迎的居住城市之一。这个城市的人口增长很快。在温哥华北部的海岸有一些世界上最古老、 最美丽的森林。那儿的湿度很大，所以树长得特别高，有一些经测量高达90多米。”那天下午表姐妹俩登上火车落了座。那天早些时候，当她们穿越落基山脉时，她们总算看到了一些野山羊，甚至还看到了一只灰熊和一只鹰。她们的下一站是卡尔加里，这个城市因“大西部赛马会”而闻名。来自世界各地的牛仔们来参加赛马会比赛。他们中许多人都有骑野马的天赋，他们能赢得几千美元的奖金。两天的旅行以后，表姐妹俩开始意识到加拿大的确人烟稀少。 在学校，她们学过大多数加拿大人居住在靠近美国几百千米以内的边境地带，并且加拿大的人口只有三千万多一点儿。但是现在看到一个这么空旷的国家， 她们很惊讶。她们穿过一个种植小麦的省份， 看到

了面积有数千英亩的农场。晚饭后，她们又回到城市，位于五大湖区最北端的繁忙的港口桑德湾。海轮可以开到五大湖，这让两个女孩感到吃惊。她们了解到，因为这五大湖，加拿大的淡水比世界上任何一个国家都要多。 事实上，加拿大拥有全世界三分之一的淡水， 其中大部分都蓄积在五大湖里。那天夜里她们睡着了，火车越过苏必利尔湖北部，穿过大森林，朝南向多伦多飞驰着。［学生用书P133（单独成册）］I阅读理解AItwasacoldmorning,andEduardoOrtegawasnervous.Heheldalargeenvelope.Initwashisdream.“Thisiseverythinghesaid."I'veworkedforthissinceIwasayoungboy.”Eduardorememberedthelonghoursworkinginthefields,pickingstrawberriesandbeans.Aftertheworkday,histiredfriendsdrankcoffeeorslept.Eduardostudied,read,andwrotepoetryandshortstories.Althoughhemissedmanyclasses,hebecametheschoolsbeststudent.Oneschoolyear,Eduardowroteanessay仅章）andwonaprize—aflyingtriptoSanFrancisco.Asheflew,hefeltfreefromhislifeofhardworkinthefields.Hepromisedhimselfnottoreturntothatlife.Helovedtofly.Thismorning,Eduardocaughttheschoolbusandwenttoschoolwiththeenvelope.Hewalkedpasthisclassmatesandsatdownathisdesk.Heopenedtheenvelopeandbeganreadingtheletterinside.Itwastheanswertohisapplicationtothestateuniversity.Itwasalsotheanswertothebeginningofhisdreamofbecomingapilot.EventhoughEduardoworkedtohelphisfamily,hisfatheralwaysencouragedhimtogotoschool.So,whileheworked,healsostudied.Eduardoknewthathisdreamwashisfather'sdream,too.Hisfatherwasasmartman,buthewastoopoortogotocollege.Helovedtoread,butneverhadtime,becauseheworkedlonghours.Now,asEduardoreadthewords,aCongratulations...youhavebeenaccepted；'heknewthathisdreamwasnotlost.Oneday,hewouldbeapilot,flyingeverydaytoalltheexcitingplacesintheworld.【解题导语】 本文是一篇记叙文。男孩家境不好，需要打零工帮助家里维持生计，但他并没有放弃自己的梦想。 他坚持学习，通过不懈的努力终于考上了大学 ，缩短了与梦想的距离。WhatdidEduardodowhenhisfriendsdrankcoffeeorslept?Heattendedclasses.Hestudiedandwrote.Heworkedinthefields.Hehelpedaroundhishome.B解析：细节理解题。由第三段中的Aftertheworkday,histiredfriendsdrankcoffeeorslept.Eduardostudied,read,andwrotepoetryandshortstories.可知，工作结束后,他的朋友们或喝咖啡或睡觉，而他却在学习和写作。WhatwasEduardo'sdream?A.Becomingapilot.Becomingawriter.Travelingaroundtheworld.Realizinghisfather'sdream.A解析：细节理解题。由第五段中的 Itwasalsotheanswertothebeginningofhisdreamofbecomingapilot.和最后——段中的Oneday,hewouldbeapilot,flyingeverydaytoalltheexcitingplacesintheworld.可知，他梦想成为一名飞行员。
