Section Two Listening ComprehensionPart 1 DialogueA UN InterpreterInterviewer: . so perhaps you could tell us how exactly you became so proficient at language learning, Suzanne. Suzanne: Well, I think it all started with a really fortunate accident of birth.

10、You know I was born in Lausanne*, Switzerland; my father was Swiss-French Swiss and my mother was American, so, of course, we spoke both languages at home and I grew up bilingual. Then, of course, I learnt German at school - in Switzerland that's normal. And because I was already fluent in Engli

11、sh, my second language at school was Italian. So I had a real head start (有利的开端)! Interviewer: So that's . one, two, three, four - you had learnt four languages by the time you left school? How fluent were you? Suzanne: Urn, I was native speaker standard in French and English, but I'd become

12、 a bit rusty* in German and my Italian was only school standard. I decided the best option was to study in the UK, and I did Hispanic Studies at university, studying Spanish and Portuguese, with some Italian, and living in Manchester. Then I went to live in Brazil for two years, teaching English. In

13、terviewer: So by this time you must have been fluent in six languages? Suzanne: Nearly. My Italian wasn't perfect, but I had a boyfriend from Uruguay* while I was there, so my Spanish also became pretty good! Interviewer: And then what did you do? Suzanne: When I was 25 I came back to Switzerlan

14、d, went to an interpreters' school and then got a job in the United Nations when I was 28. Interviewer: And you've been there ever since? Suzanne: Not quite. In the first few months I met Jan, a Czech interpreter, who became my husband. We went to live in Prague in 1987 and that was where I

15、learnt Czech. Interviewer: And the eighth language? Suzanne: Well, unfortunately the marriage didn't last; I was very upset and I decided to take a long break. I went to Japan on holiday, got a job and stayed for two years, which was when I learnt Japanese. Interviewer: That's amazing! And n

16、ow you're back at the United Nations? Suzanne: Yes. Well, I never really left. I carried on doing work for them when I was in Prague - some in Prague, some in Austria and Switzerland, and I took a "sabbatical*" to work in Japan. They need people who can understand Japanese. But, yes, I

17、've been back with them full-time for two years now. Interviewer: And your plans for the future? Suzanne: I'm going to learn more Oriental languages. It was such a challenge learning Japanese - it's so different from all the others. So I'll spend another two or three years here with

18、the UN full-time, during which time I hope to get a substantial promotion, then I think I'll go back and learn Korean, or perhaps Chinese, and Thai - I'd love to learn Thai. And then, perhaps an Indian language. Whatever, I want to be fluent in another three or four languages before 45. Exer

F Part 2 Passage The Clyde River Running through one of Britain's biggest manufacturing centers, Glasgow, the Clyde River* was poisoned for more

20、 than a century by the fetid* byproducts of industry. The waterway bore the brunt of (首当其冲)Glasgow's economic success during the Industrial Revolution and beyond, as pollution and chemicals destroyed its fish and wildlife populations and brewed smells whose memory still makes residents wince*. N

21、ow, with heavy industry gone and Glasgow reconceived as a center for culture and tourism, the Clyde is coming back to life. For the first time since the late 1800s, its native salmon have returned in sizable numbers, reflecting the new cleanliness of a river that was once one of Britain's filthi

22、est. The Clyde River Foundation surveyed fish populations last autumn at 69 sites in the Clyde and its tributaries, and found salmon in seven of the nine major tributaries. The migratory fish, which vanished from the Clyde around 1880 after a long decline, first reappeared in the 1980s, but last yea

23、r's survey was the first to show they've come back in healthy numbers. Although commercial salmon fishing was never widespread on the Clyde, the fish's return is symbolically important for Glasgow, where salmon were once so important to the city's identity that two are pictured on it

24、s official coat of arms. The salmon's comeback is also a sign of big improvements to water quality. Like sea trout, which have also reappeared in the Clyde system in recent years, salmon are very sensitive to environmental conditions and require cool, well-oxygenated* water to thrive. The declin

25、e of Glasgow's main industries helped boost the fortunes of a river that was essentially fishless for decades during the worst periods of pollution. The closure of factories that had poured toxins* and other pollutants into the river boosted water quality significantly. Environmental regulators

26、also lightened dumping rules, and modern sewage processing plants helped eliminate some of the foul* smells that once tainted* the air. With worries rising about the environmental impact of enormous fish farms elsewhere in Scotland and severely depleted fish stocks in the North Sea and North Atlanti

27、c, the Clyde comeback is a rare bit of good news for Scotland's fish lovers. Since the area that is now Glasgow was first settled around the year 550, the Clyde has been central to its history. The river's depth and navigability helped make Glasgow an important center for importing tobacco,

28、sugar and cotton from the Americas starting in the 1600s. Later, during the Industrial Revolution that began in the late 1700s, Glasgow became a center of British shipbuilding and one of the country's great manufacturing centers. The mills and factories that lined the Clyde made steel, textiles

29、and chemicals, tanned leather and even produced candy and brewed alcohol. When the factories began to close in the second half of the 20th century, working-class Glasgow, Scotland's largest city, gained a reputation for social deprivation and rough streets. More recently, its art museums and nig

44、 Adaptation to Climate ChangeScientists predict the world will get hotter over the coming decades. A major conference in Copenhagen at the end of the year will focus on ways to mitigate the worst affects of global warming. WMO Secretary-General Michel Jarraud (世界气象组织秘书长贾侯)says countries must have th

45、e tools to adapt to a changing climate. They must be able to respond to a world that is likely to experience more extreme weather events, such as floods and hurricanes. Jarraud notes farmers in certain parts of the world will have to adapt to a dryer climate. He says they might have to modify irriga

46、tion systems or consider growing crops that do not require much rain.He says global warming is likely to increase the intensity and frequency of extreme weather events. Therefore, better and more timely information on these phenomena are essential to make decisions on climate variability and change.

47、 To do this, he says, weather observation networks must be strengthened. The WMO chief says climate change is a global problem. And, everyone needs everyone else to solve this problem. He says even the biggest, richest countries cannot do it alone. He says the developed world needs reliable weather

An unexpected discovery at the sout

53、hern end of the reef has provided some rare good news for researchers.Researchers found that coral in the Keppel Islands off Queensland, which was damaged by bleaching in 2006 and then smothered by seaweed that overgrew the reef, has managed to repair itself.Experts say to see reefs bounce back from

54、 mass coral bleaching in less than a decade is highly unusual.Like other coral systems, the Great Barrier Reef is facing a range of environmental threats. Scientists say their capacity to recovery from damage inflicted by warmer waters, for example, will be critical to its future health.The Great Ba

The global event has been endorsed by the Secretary-General of the United Nations. Ban Ki-moon has said it was the biggest climate change demonstration ever

Organizers are hoping that up to a billion people from small villages in Namibia to sprawling cities in Asia will participate in an international effort to cut greenhouse gas em

One of the architects of Earth Hour, Andy Ridley from the conservation group World Wildlife Fund (WWF), says the current financial meltdown should not be used as an excuse to delay environmental reforms.
