Around noon they arrived in Toronto, the biggest and most wealthy⑦ city in Canada⑧. They were not leaving for Montreal until later, so they went on a tour of⑨ the city. They went up the tall CN Tower⑩ and looked across the lake. In the distance?， they could see the misty? cloud that rose from the great Niagara? Falls, which is on the south side of the lake. The water flows into the Niagara River? and over the falls on its way to the sea. They saw the covered stadium, home of? several famous basketball teams. As they walked north from the harbour area?， Li Daiyu said, “Lin Fei, one of my mothers old schoolmates?， lives here. I should phone her from a telephone booth?.” They met Lin Fei around dusk in downtown? Chinatown, one of the three in Toronto. Over dinner? at a restaurant called The Pink Pearl， the cousins chatted with Lin Fei, who had moved to Canada many years earlier. “We can get good Cantonese food here，” Lin Fei told them, “because most of the Chinese people here e from South China, especially Hong Kong. Its too bad you cant go as far as Ottawa, Canadas capital. Its approximately four hundred kilometres northeast of Toronto, so it would take too long.” ①bush/b??/n.灌木(叢); 矮樹(叢) ②maple/meIpl/n.楓；楓樹 ③frost/fr?st/n.霜；霜凍 ④confirm/k?nf??m/vt.證實；證明；批準 ⑤fall[美]＝autumn[英]秋天 ⑥現(xiàn)在分詞短語confirming that ...作狀語。 ⑦wealthy/welθI/adj.富有的 ⑧the biggest and most wealthy city in Canada是Toronto的同位語。 ⑨go on a tour of游覽…… ⑩CN Tower (Canada National Tower)加拿大國家塔 ?in the distance在遠處 distance/dIst?ns/n.距離；遠方 ?misty/mIstI/adj.有薄霧的；模糊的 mist/mIst/n.薄霧 ?Niagara/naIɡ?r?/n.尼亞加拉(河；瀑布) ?the Niagara River尼亞加拉河 ?covered是過去分詞作前置定語，意為“覆蓋的”，即“加了頂?shù)摹薄ome of ...作stadium的同位語。 ?As they walked ...是as引導(dǎo)的時間狀語從句。 ?schoolmate/sku?lmeIt/n.同學(xué)；校友 ?booth/bu?θ/n.公用電話間；貨攤；售貨亭 ?downtown/?da?nta?n/adj.市區(qū)的adv.在市區(qū)；往市區(qū) ?over dinner＝during dinner吃飯期間；用餐時 過去分詞短語called The Pink Pearl作后置定語，修飾restaurant。 Cantonese/?knt?ni?z/n.&adj.廣東人(的)；廣州人(的)；廣東話(的) as far as達到……，和……一樣遠 approximately/?pr?ksIm?tlI/adv.接近；大約 用于數(shù)字之前，相當于about。 多倫多—蒙特利爾的“真北方”號列車 [第1～4段譯文] 第二天早上，在她們的車窗外到處是灌木叢和楓樹，掛滿朱紅、赤金和橘黃色的葉子，地面上覆蓋了一層薄霜，表明秋天已經(jīng)來到了加拿大。 中午時分，她們到達了多倫多——加拿大最大、最富有的城市。她們要晚些時候才動身去蒙特利爾，因此她們就在多倫多市內(nèi)游覽了一番。她們登上了高高的加拿大國家塔，俯瞰著下面的湖水。在遠處，她們可以看到在湖的南邊尼亞加拉大瀑布上方升騰著的霧靄。湖水流入尼亞加拉河，再經(jīng)過大瀑布，流向大海。 她們看到了加頂?shù)拇笮瓦\動場，那是幾支著名的籃球隊的駐地。當她們從港口區(qū)向北走的時候，李黛予說：“我媽媽的一個老同學(xué)林菲住在這里，我該到電話亭去給她打個電話?！? 黃昏時分，她們在市區(qū)的中國城見到了林菲，這是多倫多三個中國城中的一個。在一個名叫“海珠酒樓”的餐館里用餐時，表姐妹和許多年前就移居加拿大的林菲閑聊了起來。林菲告訴她們：“我們在這里可以吃到可口的廣東菜，因為這里的大多數(shù)中國人來自中國南方，尤其是香港。很可惜你們不能一直走到加拿大的首都渥太華。它在多倫多東北方約400千米處，因此要去那兒花的時間就太多了?！? The train left late that night and arrived in Montreal at dawn the next morning. At the station, people everywhere were speaking French. There were signs and ads in French, but some of them had English words in smaller letters. “We dont leave until this evening，” said Liu Qian. “Lets go downtown. Old Montreal is close to the water.” They spent the afternoon in lovely shops and visiting artists in their workplaces beside the water. As they sat in a buffet restaurant looking over the broadSt Lawrence River， a young man sat down with them. “Hello, my name is Henri. Im a student at the university nearby，” he said, “and I was wondering where you are from.”The girls told him they were on a train trip across Canada and that they had only one day in Montreal. “Thats too bad，” he said. “Montreal is a city with wonderful restaurants and clubs. Most of us speak both English and French, but the city has French culture and traditions. We love good coffee, good bread and good music.” That night as the train was speeding along the St Lawrence River toward the Gulf of St Lawrence and down to the distant east coast, the cousins dreamed of French restaurants and red maple leaves. at dawn黎明時分 dawn/d??n/n.黎明；拂曉；破曉 visiting前省略了介詞in。本句含句式：spend＋時間＋(in)doing。 workplace/w??kpleIs/n.工作場所；工作地點 buffet/b?feI/n.自助餐；飲食柜臺 broad/br??d/adj.寬闊的；廣泛的 broad著重指幅面的寬廣；wide著重指從一邊到另一邊的距離。 board/b??d/n.板，木板；董事會v.上(船、飛機、火車等) St Lawrence/seIntl?r?ns/River圣勞倫斯河 As they sat ... looking over ..., as引導(dǎo)時間狀語從句，從句中現(xiàn)在分詞短語looking over ...作伴隨狀語。 nearby/nI?baI/adv.在附近adj.附近的；鄰近的 nearby既可作前置定語，也可作后置定語。 where引導(dǎo)賓語從句，作wondering的賓語。 told后跟了兩個賓語從句，第一個that在him后，被省略了。 tradition/tr?dI?n/n.傳統(tǒng)；風(fēng)俗 by tradition按照傳統(tǒng) in the tradition of沿襲……的傳統(tǒng) speed v．加速，促進n.速度 dream of夢到；想到 [第5～7段譯文] 火車在那一夜的晚些時候起程了，第二天黎明時分到達了蒙特利爾。在火車站，人們到處說的是法語。指示牌和廣告也都是法文的，但有些標注了小字體的英文。劉倩說：“我們要到傍晚才動身，不如到市區(qū)去走走。蒙特利爾老區(qū)是在水邊上的?！闭麄€下午她們穿梭于布局可愛的商店中，還拜訪了水邊工作坊里的藝術(shù)家們。當她們坐在一家自助餐廳里眺望廣闊的圣勞倫斯河時，一個年輕人坐到了她們的身邊。 “你們好，我叫亨利，是附近的大學(xué)生。”他說道，“我想知道你們從哪兒來？”姑娘們告訴他，她們是坐火車來旅游的，要橫穿加拿大，在蒙特利爾只待一天。他說：“這太糟糕了，蒙特利爾這座城市有極好的餐館和俱樂部。我們大多數(shù)人既講英語又講法語，但是這座城市具有法國文化和傳統(tǒng)。我們喜歡醇厚的咖啡、好吃的面包和優(yōu)美動聽的音樂?！? 那天晚上，火車沿著圣勞倫斯河疾馳，朝圣勞倫斯灣駛?cè)?，一直開到遠方的東海岸，表姐妹夢到了法國餐館和紅色楓葉。 Step 1 True (T) or False (F)． 1．Lin Fei was a Chinese who had moved to Canada many years ago.(　　 ) 2．They arrived in Montreal late that night.(　　 ) 3．Toronto is the wealthiest city in Canada.(　　 ) 答案：1.T　2.F　3.T Step 2 Choose the best answers according to the text. 1．What is the main idea of this part?

But its far too early to add dusting to a weightloss plan. Dietary fats and other materials that make up indoor dust can send a signal to human fat cells, telling them to grow. That process, in turn, might slow the bodys rate of burning energy. Such changes could add to any weight problems a person might have. “We dont know what that means to longterm health and certain diseases yet，” says Heather Stapleton, one of the studys authors. But she notes that her teams findings also raise a question of whether pollutants (污染物) in dust might play some role in the growing, global problem of obesity. Stapleton and her colleagues collected dust from homes and offices. Studies found that some materials in the dust could turn on a protein (蛋白質(zhì)) called PPARgamma 1. Its found in many human tissues. Turning this protein on can cause fat cells to grow. Researchers think this protein may be involved in obesity. But a second study now finds evidence that certain fats are mostly to blame. Cooking oils may send out some of these fats into the air, where they eventually find their way into house dust. Or, the authors say, the fats might enter house dust as part of the hair or skin cells shed (脫落) by people or pets. “While the findings are amazing，” says Mitchell Lazar, another study author, “these findings need to be taken as very preliminary.” Indeed, he adds several cautions about how the findings should be understood. “For one thing, people eat these fats in foods all of the time. That is likely to be a lot more than would be consumed from indoor dust，” he said. 1．What can be concluded from the research? A．Dust harms peoples health. B．Dust can help people lose weight. C．Dust is a cause for some diseases. D．Dust may have something to do with weight. 解析：選D　推理判斷題。由第二段最后一句可知，家里的灰塵可能與肥胖有一定的關(guān)系。 2．What do we know about PPARgamma 1? A．It es from dust. B．It leads to weight gain. C．It can help get rid of dust. D．It only appears in human bodies. 解析：選B　細節(jié)理解題。由第三段“Turning this protein on can cause fat cells to grow.”可知，此蛋白質(zhì)能引起肥胖。 3．The underlined word “preliminary” in the last paragraph can be replaced by “______”． A．limited　　　　　　 B．important C．misleading D．unbelievable 解析：選A　詞義猜測題。由下句“Indeed, he adds several cautions about how the findings should be understood.”及他之后所說的話可知，Lazar認為此研究發(fā)現(xiàn)有一定的局限性。 4．Whats the best title for the text? A．Can house dust make us fat? B．Why is it important to clean? C．Anything to do to deal with dust? D．What is the best way to lose weight? 解析：選A　標題歸納題。從全文整體看，作者探討了家里的灰塵會不會使我們變胖的問題。 Ⅱ.語法填空 A young man, while traveling through a desert, came across a spring of clear water. __1__ water was sweet.
