Rather than① travel by commercial airline② all the way, they decided to fly to Vancouver and then take the train③. For both of them, the thought of crossing the whole country by rail was exciting. [1]此处是动词不定式短语作目的状语。 返回导航 Before starting out④， they spent a couple of days in Vancouver, seeing the sights. During their first day, [2]as is typical of⑤ Vancouver, it rained. Despite the weather, they were able to take a boat ride out into the bay⑥， and later visit an island that had wonderful shops selling crafts⑦ and antiques⑧. The next day was clear and mild⑨， and they were pleased to see the beautiful mountains looking out over the city. Later, they took a pleasant⑩ hike⑪ in a forest just a short distance away. [2]此处是as引导的非限制性定语从句。 返回导航 The next morning, the two girls arose⑫ early to take the train to Lake Louise, passing through the Canadian Rockies. [3]Seen from the train window, the mountains and forests of Canada looked massive⑬. When the train arrived at the station, they took a taxi to Lake Louise, where the blue water literally⑭ took their breath away⑮ with its exceptional beauty. They spent the night, and then took a coach bound⑯north through the Canadian Rockies to Jasper. 返回导航 Looking at the beautiful scenery⑰， they both agreed that it was the most awesome⑱ journey they had ever taken. In addition to⑲ seeing spectacular⑳ mountain peaks㉑ and forests, one highlight㉒of their trip was being able to see many different creatures, including deer, mountain goats㉓， and even a grizzly bear㉔ and an eagle. [3]此处是过去分词短语作状语，the mountains and forests of Canada与see之间为被动关系。 返回导航 From Jasper, they caught the train towards Toronto. One of the train's first stops was in Edmonton, the provincial capital of Alberta, the centre of Canada's huge oil and gas drilling㉕ industry. Edmonton is freezing cold㉖ in winter, [4]with daily temperatures averaging －10 ℃．[5]Since it can be too cold to go outdoors, Edmonton is home to㉗ many shopping malls㉘. In fact, one of the largest shopping malls in North America is in Edmonton. [4]此处是with复合结构作状语。 [5]此处是since引导的原因状语从句。 返回导航 From Edmonton, the train headed㉙ southeast across the great Canadian Prairie㉚. At school, Daiyu and Liu Qian had learnt that Canada's population is only slightly over thirty-seven million. However, they did not anticipate㉛ seeing such an open country, and were truly amazed. They went through two wheat-growing provinces, where they saw a bunch of㉜ farms that covered a very large area. 返回导航 After another day on the train, eventually㉝they were back in an urban area, the city of Winnipeg.From there, they travelled through the night, and woke up in Ontario—a land of forests and lakes. The train thundered㉞ on, through the rolling hills. The bushes and maple trees outside their windows were red, gold, and orange, and there was frost㉟on the ground, 返回导航 [6]confirming㊱ that autumn had arrived in Canada. Night came again, and the train turned south towards Toronto.When they woke up the next morning and pulled back the curtains㊲， they could see the wide stretch of Lake Huron—one of the four Great Lakes on Ontario's southern border㊳. [7]It was not until 9：30 a.m. that they finally reached the capital of Ontario，Toronto. All in all㊴， their trip from Vancouver to Toronto had taken a duration㊵ of four days. [6]此处是现在分词短语作状语。 [7]本句是强调句型，被强调的部分是时间状语not until 9：30 a．m.。 返回导航 坐火车看“真北方”： 温哥华与加拿大腹地 李黛予和她的表妹刘倩前往加拿大去探望她们居住在大西洋海岸哈利法克斯市的表兄妹。她们没有一路乘坐商业航班，而是决定先飞到温哥华，然后再乘坐火车。一想到可以坐火车横穿整个国家，姐妹俩就激动不已。 返回导航 出发前，她们在温哥华待了两天，欣赏当地风光。第一天，温哥华一如往常，细雨蒙蒙。尽管天气不佳，她们仍然乘船驶入海湾，接着游览了一座岛屿，岛上有精致的店铺，出售手工艺品和古董。第二天，天气晴朗，温度适宜，她们看到壮美的群山俯瞰着整座城市，甚是欣喜。随后，她们在不远处的森林中徒步旅行，十分惬意。 返回导航 次日清晨，两个女孩早早起床，坐上开往路易斯湖的火车，穿越加拿大的落基山脉。从车窗往外望去，加拿大的群山巍峨、森林辽阔。火车抵达车站后，她们乘出租车来到路易斯湖，那里湛蓝的湖水异常美丽，令她们惊叹不已。她们在那里度过了一晚，然后乘坐长途汽车，向北穿越加拿大的落基山脉，来到贾斯珀。望着眼前的美景，两人一致认为这是她们所经历过的最棒的一次旅行。除了欣赏壮丽的山峰和森林，旅程的亮点之一是能看到种类繁多的动物，如鹿、山羊，甚至还有一头灰熊和一只鹰。 返回导航 在贾斯珀，她们坐上了开往多伦多的火车。列车的前几站中有一站是埃德蒙顿，这是阿尔伯塔的省会，也是加拿大巨大的油气开采业的中心。埃德蒙顿冬季十分寒冷，日平均气温为零下10摄氏度。由于天寒地冻，不适合户外活动，因此埃德蒙顿拥有众多大型购物中心。事实上，北美最大的购物中心之一就在埃德蒙顿。 返回导航 列车从埃德蒙顿出发，朝东南方向一路驶过加拿大大草原。黛予和刘倩在学校学过，加拿大的人口仅有3 700多万。但两人还是没能料到能看到如此空旷的国家，实在是惊叹不已。她们还路过了两个种植小麦的省份，在那里她们看到了大片大片广阔的农场。 返回导航 她们在火车上又度过了一天，最终回到了市区——温尼伯市。从该市出发，她们连夜前行，醒来时发现已抵达森林和湖泊密布的安大略省。火车继续轰隆隆地向前行驶，穿过绵延的群山。窗外的灌木丛和枫树林呈红色、金色和橘黄色，地面盖着一层霜，表明加拿大已进入秋季。夜幕再次降临，火车转向南行，开往多伦多。次日清晨，当她们醒来，拉开车窗窗帘时，辽阔的休伦湖映入眼帘——休伦湖是安大略省南部边境的四大湖之一。直到上午九点半，她们才终于抵达安大略省的省会多伦多。从温哥华到多伦多，她们的旅行总共历时四天。 返回导航 教材原文助读8 PART 02 第二部分 26 ①kill v．[熟词生义]消磨，打发 kill time(等待时)消磨时间，打发时光 ②proceed [prə'siːd] vi.行进；继续做 proceed to sth.进而做(参加)　 ③shore [ʃɔː(r)] n．岸；滨 ④in the distance 在远处 返回导航 ⑤astonish [ə'stɒnIʃ] vt. 使十分惊讶；使吃惊 astonishing adj.令人惊讶的 astonished adj.感到惊讶的 ⑥misty ['mIsti] adj.多雾的；模糊的 mist [mIst] n．薄雾；水汽 ⑦flow into流入 ⑧on one's way to... 在去……的路上；即将…… 返回导航 ⑨steel [stiːl] n.钢；钢铁工业 ⑩old-fashioned adj.陈旧的；过时的，不时髦的 ⑪roll by 驶过；流逝 ⑫available adj.(人)有空的；(东西)可获得的，可购得的，可找到的 ⑬dusk [dʌsk] n．黄昏；傍晚 at dusk在黄昏 ⑭chat with...与……聊天 ⑮all kinds of各种各样的 返回导航 ⑯in contrast to与……相反；与……截然不同；相比之下 in/by contrast相比之下 ⑰advertisement [əd'vɜːtIsmənt； NAmEˌædvər'taIz-] n．(informal ad)广告；启事 advertise v．(为……)做广告，登广告；征聘，公布 advertise for为……做广告 返回导航 ⑱speak English with an accent说英语带有口音 accent ['æksent]n．口音 ⑲spend time (in) doing sth. 花费时间做某事 ⑳photographer [fə'tɒɡrəfə(r)] n．摄影师；拍照者 ㉑owe [əʊ] vt.欠(账、债、情等)　 owe sth. to sb.欠(某人情)；把……归功于某人 owe it to yourself/ yourselves你(们)应该 返回导航 ㉒overall adv.一般来说；大致上；总体上 ㉓toast [təʊst] n．烤面包片；吐司；干杯 vt.为……干杯 vt.& vi.烤(尤指面包) ㉔speed v．快速前行 ㉕dream of梦见；梦想 ㉖cobblestone ['kɒblstəʊn] adj.铺有鹅卵石的 返回导航 SEEING THE TRUE NORTH VIA RAIL：TORONTO AND MONTREAL After Li Daiyu and her cousin arrived in Toronto, the largest and wealthiest city in Canada, they only [1]had a few hours to kill① before they had to proceed② to the next leg of their trip to Montreal, [1]此处是“have sth. to do”结构，意为“有某事要做”。 返回导航 so they went on a tour of the city.They went up the CN Tower and looked across the shores③ of Lake Ontario.[2]Standing in the distance④， they were astonished⑤ [3]to see misty⑥ clouds rising from the great Niagara Falls, [4]which is on the south side of the lake. Water from the lakes flows into⑦ the Niagara River and over the falls on its way to⑧ the sea. [2]此处是现在分词短语作时间状语。 [3]此处是动词不定式短语作原因状语，see misty clouds rising为“see＋宾语＋宾语补足语”结构。 [4]此处是which引导的非限制性定语从句，修饰先行词Niagara Falls。 返回导航 The girls saw hundreds of skyscrapers of glass and steel⑨， and old-fashioned⑩ cars rolling by⑪. [5]As they walked north from the harbour area, Li Daiyu said, “Lin Fei, one of my mother's old schoolmates, lives here. I should phone her and see if she's available⑫ for dinner.” [5]此处是as引导的时间状语从句，as意为“在……的时候”。 返回导航 They met Lin Fei around dusk⑬ over dinner at a restaurant in downtown Chinatown.The cousins chatted with⑭ Lin Fei, [6]who had moved to Canada many years earlier． [6]此处是who引导的非限制性定语从句，修饰先行词Lin Fei。 返回导航 “This is the largest Chinatown in Toronto.We have a few more in the Greater Toronto Area, so you can guess that there are a lot of Chinese people in Canada! Chinese people [7]have been coming here for more than a hundred years.Therefore, we can get all kinds of⑮ great food here from all over China，” Lin Fei told them. [7]此处是现在完成进行时，表示动作从过去某一时间开始，一直持续到现在，并且可能会继续下去。 返回导航 The train left late that night and arrived in Montreal early the next morning.At the station, in contrast to⑯Toronto, they [8]heard people talking in French.They were surprised [9]to see that all the signs and advertisements⑰ were in French and many people spoke English with an accent⑱． [8]此处是“hear sb. doing sth.”结构，意为“听到某人在做某事”。 [9]此处是动词不定式短语作原因状语。 返回导航 “We don't leave until this evening，” said Liu Qian.“Let's go downtown.Old Montreal is close to the water.” They spent the afternoon in lovely shops and visiting⑲ artists in their workplaces along St Paul Street.As they sat in a restaurant alongside the broad St Lawrence River, a young man sat down with them. “Hello, my name is Jean-Philippe.I'm a photographer⑳，” he said, “and I was wondering where you are from.” 返回导航 The girls told him they were from China and were on a train trip across Canada. When they told him they had only one day in Montreal, he said，“That's too bad. You owe㉑ it to yourselves to stay longer.Overall㉒， Montreal is a city [10]with wonderful sights and sounds．Most of us speak both English and French, and the city has unique Quebec culture and traditions.There are fantastic restaurants and clubs around, too.Here, we love good coffee, toast㉓， and cheese. And good music, of course！” [10]此处是介词短语作定语，修饰a city。 返回导航 That night the train was speeding㉔ along the St Lawrence River towards the Gulf of St Lawrence and down to the distant east coast towards the province of Nova Scotia and its largest city, Halifax.The cousins dreamt happily of㉕ the beautiful cobblestone㉖ streets, old brick buildings, and the red maple leaves of Montreal. 返回导航 通过铁路看到真正的北方：多伦多和蒙特利尔 李黛予和她的表妹来到加拿大最大、最富有的城市多伦多后，离出发前往下一站蒙特利尔之前只有几个小时的时间，于是她们就在多伦多逛了逛。她们登上加拿大国家电视塔，眺望安大略湖的对岸。站在远处，她们看到湖南边尼亚加拉大瀑布升腾而起的水雾，感到非常震撼。湖水流入尼亚加拉河，越过瀑布流向大海。 返回导航 两个女孩看到了成百上千的由玻璃和钢铁建成的摩天大楼，还看到了驶过的老式汽车。当她们从港区往北走时，李黛予说：“我母亲的一个老同学林菲住在这里。我得给她打个电话，看看她是否有空共进晚餐。” 黄昏时分，她们在市中心唐人街的一家餐馆里跟林菲见面吃饭。这对表姐妹和林菲聊了起来，林菲早在很多年前就搬到了加拿大。 返回导航 “这是多伦多最大的唐人街。大多伦多地区也还有几处唐人街，所以你可以猜到在加拿大有很多中国人！一百多年来，中国人一直持续不断地来到这里。因此，我们可以吃到各种各样来自中国各地的美食，”林菲告诉她们。 火车当天深夜离开，第二天清晨到达蒙特利尔。与多伦多不同的是，她们在车站听到人们用法语交谈。她们惊讶地发现所有的指示牌和广告都是用法语写的，许多人说英语带有口音。 返回导航 “我们直到今晚才离开，”刘倩说。“我们去市区逛逛吧。蒙特利尔旧城离水很近。” 她们在圣保罗街上可爱的商店里度过了一个下午，并拜访了工作场所里的艺术家。当她们坐在宽阔的圣劳伦斯河边的一家餐馆里时，一位年轻男士也坐了下来。 “你们好，我叫让·菲利普，是一名摄影师，”他说，“我想知道你们是哪里人。” 返回导航 女孩们告诉他，她们来自中国，正在乘火车穿越加拿大。当她们告诉他，她们在蒙特利尔只待一天的时间时，他说，“那太可惜了。你们应该多待一会儿。总的来说，蒙特利尔是一座声色俱佳的城市。我们大多数人既说英语也说法语，这座城市拥有独特的魁北克文化和传统。周围还有很棒的餐馆和俱乐部。我们这里的人喜欢美味的咖啡、烤面包片和奶酪。当然还有动听的音乐！” 返回导航 那天晚上，火车沿着圣劳伦斯河向圣劳伦斯湾飞驰，沿着遥远的东海岸驶向新斯科舍省和该省最大的城市哈利法克斯。这对表姐妹愉快地梦见蒙特利尔美丽的铺有鹅卵石的街道、古老的砖砌建筑和红枫树叶。 返回导航 $
