New Product Will Save Lives

Drinking water that looks clean may still contain bugs(虫子) ,which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Parton, who started Genera five years ago. He and his employees have developed the test together with a British water company.

Andy Headland, Genera's marketing director, recently presented the test at a conference in the USA and forecast good American sales for it. Genera has already sold 11 of its tests at

$ 42,500 a time in the UK and has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government. Genera was formed five years ago and until October last year had only five employees;it now employs 14. Mr.Headland believes that the company should make around $19 million by the end of the year in the UK alone.

Alaska

1In 1868 Americans welcomed Alaska into the Union as the 49th state, symbolizing a change of attitude from that held in 1867 ,when the peninsula was purchased from Russia. Then, most Americans had litt le interest in 1,500,000 square kilometers “of icebergs and polar bears”—beyond Canada's western borders, far from the settled areas of the United States.

2In those sections of the state which lie above the Arctic Circle, Alaska still is a land of icebergs and polar bears. Ice masses lie buried in the earth, which is permanently frozen to a depth of 90 or more meters. From early May until early August, the midnight sun never sets on this flat, treeless region, but the sun cannot melt the icy soil more than two-thirds of a meter down.

3Alaska is America's largest state, but only about 325,000 people live there. According to estimates, 800,000 hectares of its land area are fit for plowing but only about 640,000 hectares are being cultivated.

4Arctic Alaska has been the home of Eskimos for countless centuries. It is believed that the Eskimos moved there from Mongolia or Siberia, probably crossing Bering Strait, named for Vitus Bering, the Danish sea captain who discovered Alaska on his voyage for Russia in 1741. The Eskimos are the state's earliest known inhabitants. Russian fur traders established settlements but, by the time Alaska was sold to the United States, most of the traders had departed.

5In 1896 gold was discovered near the Klondike River in Canada just across the Alaskan border. Thousands of Americans rushed to the region on their way to Klondike; some never returned. Alaska was never completely cut off again, although even today transportation is a major problem. There are only two motor routes from the U. S. mainland, and within the state, every town has its own airfield. Planes fly passengers, mail and freight to the most distant villages.

6The gold that changed life so suddenly for Alaska was soon ended, and although many stories about mining camps have become part of American literature, the gold from Alaskan earth contributed less to economic progress than the fish from Alaskan waters. The fish caught in a single year range in value from $ 80 million to $ 90 million. Fur-bearing animals are plentiful in the forests and streams, and valuable fur seals inhabit the waters. After fishing, the state's chief industry is lumber and the production of wood pulp. In recent years, Alaska's single most

important resource has become oil. The state also has large deposits of coal, copper, gold and other minerals.

Sauna

Ceremonial bathing has existed for thousands of years and has many forms, one of which is the sauna. The Finns have perfected the steam bath, or sauna, which may be taken, usually in an enclosed room, by pouring water over hot rocks or as dry heat bath. The Japanese, Greeks, Turks and Russians as well as Native Americans have forms of the sweat bath in their bathing rituals.

Dry heat and steam baths had advocates in ancient Rome and pre-Columbian Americans used sweat lodges.

The earliest saunas were probably underground caves heated by a fire that naturally filled with smoke as chimney making was unknown at that time. a fire kept in a fire-pit would heat the rock walls of the cave. After reaching full heat, the smoke was let out of the cave and the stones would retain heat for several hours. A few people today say that the smoke sauna, “svusauna”, is the only true sauna experience and that all saunas should have at least a back-ground odor or smoke. Today most saunas use electric stoves, although gas and wood-burning stoves are available.

Saunas are relaxing and stress relieving. Those with muscle aches or arthritis may find that the heat relaxes muscles and relieves pain and inflammation. Asthma patients find that the heat enlarges air passageways of the lung and facilitates breathing. Saunas do not cure the common cold but they may help to alleviate congestion and speed recovery time. The body's core temperature usually rises a 1-2 degrees while in the sauna, thus imitating a slight fever. The regular use of a sauna may decrease the likelihood of getting a cold in the first place.

Sauna is goof for your skin as the blood flow to the skin increases and sweating occurs. Adults sweat about 2 lbs of water per hour on average in a sauna. A good sweat removes dirt and grime from pores and gives the skin a healthy glow. The loss in water weight is temporary as the body's physiological mechanisms will quickly restore proper volumes. The cardiovascular system gets work out as the heart must pump harder and faster to move blood to the surface for heat exchange. Heart rate may increase from 72 beats per minute on average to 100-150 beats per minute.

A normal heart can handle these stresses but those with heart trouble wishing to begin to use a sauna should seek a doctor's advice. The elderly and those with diabetes should check with their doctor prior to beginning to take saunas. Pregnant women should not take saunas, particularly in the first three months. Indeed, everyone just starting out should take short sessions at first to become accustomed to this type of bath.

Mobile Phone and Diseases

A study by scientists in Finland has found that mobile phone radiation can cause changes in human cells that might affect the brain, the leader of the research team said.

But Darius Leszczynski, who headed the 2-year study and will present findings next week at a conference in Quebec(魁北克), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body.

The study at Finland's Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human cells grown in a laboratory, he said.

“We know that there is some biological response. We can detect it with our very sensitive approaches, but we do not know whether it can have any physiological effects on the human brain or human body,” Leszczynski said.

Nonetheless the study, the initial findings of which were published last month in the scientific journal Differentiation, raises new questions about whether mobile phone radiation can weaken the brain's protective shield against harmful substances.

The study focused on changes in cells that line blood vessels and on whether such changes could weaken the functioning of the blood-brain barrier, which prevents potentially harmful substances from entering the brain from the bloodstream, Leszczynski said.

The study found that a protein called hsp27 linked to the functioning of the blood-brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的), he said.

“Increased protein activity might cause cells to shrink—not the blood vessels but the cells themselves—and then tiny gaps could appear between those cells through which some molecules could pass. ” he said.

Leszczynski declined to speculate on what kind of health risks that could pose, but said a French study indicated that headache, fatigue and sleep disorders could result.

“These are not life-threatening p roblems but can cause a lot of discomfort,” he said, adding that a Swedish group had also suggested a possible link with Alzheimer's disease.

“Where the truth is do not know,” he said.

Leszczynski said that he, his wife and children use mobile phones, and he said that he did not think his study suggested any need for new restrictions on mobile phone use.

36According to Leszczynski, how does mobile phone affect one's health? _________

A Mobile phone radiation can increase protein activities and such activities can make the protective shield more permeable.

B Mobile phone radiation can shrink the blood vessels and prevent blood from flowing smoothly.

C Mobile phone radiation will bring stress to people exposed to it.

D Mobile phone radiation kills blood cells at a rapid speed.

37What's the result of the French study? _________

A The harm of mobile phone radiation is life-threatening.

B Mobile phone may affect one's normal way of thinking.

C Sleep disorders could result from mobile phone radiation.

D A protein called hsp27 is killed by mobile phone radiation.

38What kind of disease is not caused by the use of mobile phone? _________

A Fatigue.

B Headache.

C Alzheimer's disease.

D Tuberculosis.

39According to the passage, what would be the future of the use of mobile phone?

_________

A People will be forbidden to use mobile phone.

B People dare not use mobile phone because of its radiation.

C People will continue to use mobile phone.

D There will be new restrictions on the use of mobile phone.

40Which of the following is NOT true according to the passage? _________

A The research in Finland found that mobile phone radiation will affect one's brain.

B Mobile phone radiation can cause increased activity in hundreds of protein in human cells.

C Increased protein activity might cause cells to shrink.

D Lszczynski forbid his wife and children to use mobile phone after his research.

Problems of Internet

The proportion of works cut for the cinema in Britain dropped from 40 per cent when I joined the BBFC in 1975 to less than 4 per cent when I left. But I don't think that 20 years from now it will be possible to regulate any medium as closely as I regulated film.

The Internet is, of course, the greatest problem for this century. The world will have to find a means, through some sort of international treaty of United Nations initiative, to control the material that's now going totally unregulated into people's homes. That said, it will only take one little country like Paraguay to refuse to sign a treaty for transmission to be unstoppable. Parental control is never going to be sufficient.

I'm still very worried about the impact of violent video games, even though researchers say their impact is moderated by the fact that players don't so much experience the game as enjoy the technical manoeuvres (策略)that enable you to win. But in respect of violence in mainstream films, I'm more optimistic. Quite suddenly, tastes have changed, and it's no longer Stallone or Schwarzenegger who are the top stars, but Leonardo DiCaprio—that has taken everybody by surprise.

Go through the most successful films in Europe and America now and you will find virtually none that we are violent. Quentin Tarantino didn't usher in a new, violent generation, and films are becoming much more prosocial than one would have expected.

Cinemagoing will undoubtedly survive. The new multiplexes are a glorious experience, offering perfect sound and picture and very comfortable seats, thins which had died out in the 1980s. I can't believe we've achieved that only to throw it away in favor of huddling around a

14-inch computer monitor to watch digitally-delivered movies at home.

It will become increasingly cheap to make films, with cameras becoming smaller and lighter but remaining very precise. That means greater chances for new talent to emerge, as it will be much easier for people to learn how to be better film-makers. People's working lives will be shorter in the future, and once retired they will spend a lot of time learning to do things that amuse them--like making videos. Fifty years on we could well be media-saturated as producers as well as audience; instead of writing letters, one will send little home movies entitled My Week.

41Which of the following about Internet is true according to the passage? _________

A The Internet is the greatest progress for this century.

B Efforts are needed to control Internet.

C Paraguay refused to sign a treaty for transmission.

D The United Nations has found ways to prevent Internet from developing.

42What kind of film does the author dislike? _________

A Violent films.

B Comedy.

C European films.

D Films acted by Leonardo.

43What does “that” in “I can't believe we've achieved that only to throw it away in favor...”(Para. 5) refer to? _________

A Digitally-delivered movies.

B Multiplexes.

C Advanced camera.

D Sound.

44What is the author's attitude toward the future of film? _________

A Positive.

B Negative.

C Uncertain.

D Worried.

45What does “media-saturated” in “Fifty years on we could well be media-saturated

as ...”(Para. 6) mean? _________

A Be tired of media.

B Be fully affected by media.

C Be driven mad by media.

D Be benefited by media.

Conservation or Wasted Effort?

The black robin (旅鸫) is one of the world's rarest birds. It is a small, wild bird, and it lives only on the island of Little Mangere, off the coast of New Zealand. In 1967 there were about fifty black robins there; in 1977 there were fewer than ten.46

Energetic steps are being taken to preserve the black robin. 47 The idea is to buy an-other island nearby as a special home, a “reserve”, for threatened wild life, including black robins. The organizers say that Little Mangere should then be restocked (重新准备) with the robin's food. Thousands of the required plants are at present being cultivated in New Zealand.

Is all this concern a waste of human effort? 48 Are we losing our sense of what is reasonable and what is unreasonable?

In the earth's long, long past hundreds of kinds of creatures have evolved, risen to a degree of success and died out. In the long, long future there will be many new and different forms of life. Those creatures that adapt themselves successfully to what the earth offers will survive for a long time.49 This is nature's proven method of operation.

The rule of selection “the survival of the fittest” is the one by which human beings have themselves arrived on the scene. We, being one of the most adaptable creatures the earth has yet produced, may last longer than most, 50 You may take it as another rule that when, at last, human beings show signs of dying out, no other creature will extend a paw (爪) to postpone our departure. On the contrary, we will be hurried out.

Life seems to have grown too tough for black robins. I leave you to judge whether we should try to do anything about it.

A Some creatures, certain small animals, insects and birds, will almost certainly outlast (比……长久)man, for they seem even more adaptable.

B Those that fail to meet the challenges will disappear early.

C Detailed studies are going on, and a public appeal for money has been made.

D Both represent orders in the classification of life.

E Is it any business of ours whether the black robin survives or dies out?

F These are the only black robins left in the world.

China to Help Europe Develop GPS Rival

China is to contribute to a new global satellite navigation system being developed by European nations. The Galileo satellite system 51 a more accurate civilian alternative to the Global Positioning System(GPS), operated by the US military. China will provide 230m Euros (USD259m) in 52 and will cooperate with technical, manufacturing and market development. “China will help Galileo to 53 the major world infrastructure for the growing market for location services,” said Loyola de Palacio, EU transport commissioner. A new center that will coordinate co-operation was also announced 54 the European Commission, the European Space Agency (ESA) and the Chinese Ministry of Science and Technology not long 55 The China-Europe Global Navigation Satellite System Technical Training and Cooperation Center will be 56 at Beijing University. China has a substantial satellite launch industry and could potentially help launch the Galileo satellites.

The US has claimed that Galileo could interfere 57 the US ability to downgrade the GPS service during military conflicts. European officials say this is unfounded and counter that US

opposition 58 the commercial challenge Galileo would present to GPS. Galileo will be precise to within a meter, while the civilian GPS service is accurate to around 10 meters.

The Galileo satellite constellation will 59 27 operational and three reserve satellites orbiting the Earth at an altitude of 23,600km. The satellites will be strung along three medium-Earth orbits at 56 degrees inclination to the equator and will provide global coverage. The system should be operational by 2008 and the entire project is expected to 60 around 3.2 billion Euros (USD3.6 billion).

The European Commission has said Galileo will primarily be used for transportation technology, scientific research, land management and disaster monitoring.

Galileo will provide two signals: a standard civilian one and in encrypted, wide-band signal 61 the Public Regulated Service (PRS). This second signal is designed to withstand localized jamming and will be used by police and military services in Europe. European Commission 62 have said China will not be given access to the PRS.

The first Galileo satellite is scheduled to launch late in 2004. Clocks on board 63 will be synchronized through 20 ground sensors stations, two command centers and 15 uplink stations.

Receivers on the ground will use time signals from the satellites to precisely calculate their 64 A “search and rescue” function will also 65 distress signals be relayed through the constellation of satellites.

16A本题的意思是：Genera技术公司研制出一种方法，这种方法可以确定水是否是清洁的。题句的意思与原文第二句相符，故选A。

17C本题的意思是：在成立Genera公司之前，Parton曾在一家英国水厂工作。原文中并没有提到公司成立前Parton是否在一家英国水厂工作，故选C。

18B本题可译为：这种新产品在美国获得了商业上的巨大成功。原文的意思是预计该产品在美国会卖得很好，还没在美国上市呢。本题句的意思与原文不符，故选B。

19A本题可译为：这种测试产品每件售价42 500美元。同原文意思相符，故选A。

20B本题可译为：年底前，Genera公司又订购了25件这种测试产品。Genera公司本身是卖这种测试产品的，不是它又订购了25件这种产品。与原文意思相反，故选B。

21C本题的意思是：英国政府正帮助Parton销售这种产品。原文根本没有提到这一信息，故选C。

22A本题可译为：最近，Genera的雇员增加了。见原文最后一段，原来公司里有5

位雇员，现在增加到14位，故选A。

23F这段虽不长，但提供了一些有关阿拉斯加面积和人口的数字。

24D本段介绍了爱斯基摩人最早是怎样来到阿拉斯加并成为这片土地永久的居民的。

25C这一段的开始虽然谈了淘金热的情况，但主要讲的还是阿拉斯加和外界的联系，以及它的不那么方便的交通情况。

26A这段介绍了阿拉斯加的几种主要的自然资源，包括鱼类、木材、丧皮、石油等。

27D本句中缺少谓语动词，在所给的六个选项中只有shines是单数第三人称的动词，后面所跟的状语day and night符合文中内容：the midnight SLln never sets。

28E本句的主语不完整，of前面缺少一个名词短语，从内容上看应填入E。

29 C but后面的被动语态的句子使我们很自然就想到或许应该有一个by短语。

30A句中出现as much wealth，后面很可能还会有一个as引导的句子，否则比较的意潮完整。

31C第一段的第一句告诉我们，ceremonial bathing有多种形式，其中一种是sauna。所以只有C是正确的选项。

32B根据文章第二段的第四个句子，smoke sauna被有些人认为是真正的sauna。句中a background odor也是指烟熏的气味。

33D该段最后一句说The regular use of a sauna may decrease the likelihood of getting a cold;第四句说they may help t0…speed recovery time;第一句说Saunas are…stress relieving。所以，A,B、C都是桑拿可以做的。第三句说Asthma patients find that the heat en—larges air passageways of the lung and facilitates breathing，这不足以说明桑拿有治愈哮喘的作用。因此，应选择D。

34A该段第三句提供了答案。

35D文章最后一段告诫几种人不能洗桑拿，包括心脏病患者、老人、糖尿病患者、孕妇等。所以D是正确的选项。

36A文章论述的是手机导致人体细胞变化，所以从“The study found that a protein called hsp27 linked to the functioning of the blood—brain barrier showed increased activity due to irradiation and pointed to a possibility that such activity could make the shield more permeable(能透过的)”可以判断答案是A。

37C从倒数第三段的末尾句可以看出，法国的研究成果是手机辐射是失眠、头痛等毛病的原因。选项中提到的是其中一条。

38D从文章内容上看，手机导致的疾病有好几种，但都是与头脑有关。用排除法可排除Tu—berculosis。

39C从最后研究人员的几句话可以判断手机影响程度到底如何还不知道，而且提到研究人员自己以及其家人还在用手机，可推测手机的使用不会因为这些还不确切的科学发现而停止。

40D此题用排除法比较容易解决。文章最后提到Leszczynski自己、家人都在用手机，没有任何迹象表明他禁止他们用手机，所以答案是D。

41B文章第二段开门见山提到因特网是个大问题，整段内容都与因特网有关，所以不难判断出作者的意见是对因特网要采取一定的控制。

42A提到暴力游戏的时候，作者表示深切的担忧，虽然他说对电影里的暴力还是比较乐观的，但接下去一段又提到欧美成功的电影几乎没有暴力的，说明作者不喜欢暴力电影。

43B第五段提到新式多幕电影院，后面以l4英寸的电脑屏幕作对比，说明that指代的是电影院，而非其他东西。

44A最后一段作者提到以后大概连信也不用写，而用拍一些家庭影片来传递信息，说明他认为电影不会湮没。

45B关键是saturated这个词，意思是饱和。因此从上下文“Fifty years on we could well be media-saturated as producers as well as audience;instead of writing letters，one will send little home movies entitled My Week.”可以判断答案是B。

46F这篇文章的主题是保护珍稀物种。文章第一段讲到，离新西兰不远的一座岛上生活着一些黑旅鸫，这些鸟已经不多了，1967年时还有50多只，1977年的时候还剩不到10只。选项F的意思是：这是世界上仅存的黑旅鸫了。逻辑上讲，这两句话的意思是讲得通的，these就指前面的black robins，故答案为F。

47C第二段第一句说，人们正采取一些积极的办法来保护这种鸟类。采取什么办法呢?选项C说，一方面详细的研究工作正在进行，另一方面人们已经募集了许多钱来从事保护工作。选项C正是对本段第一句的说明或解释，故选项C为正确答案。

48E选项E是一个问句，第三段中的第一句和最后一句也是问句。根据这个线索我们也可以做出正确选择。选项E的意思是说，黑旅鸫消失或是保存下来关我们什么事吗?把它放到原文中去，意思连起来顺畅，故选E。

49B文章第四段主要在谈地球上的万物都遵循优胜劣汰，适者生存的规律。选项B

就是这个意思。注意这里的“those”指代的是those creatures。

50A这一段还在谈适者生存的规律，其中提到地球上的人类可能比某些物种存活的长久，选项A则说的是，有些物种(一些小动物、昆虫或鸟类)却比人存活的更久。此旬意思可以和前面的意思连得上，所以选A

文章大意：中国要捐欧洲国家正在开发的全新的全球卫星定位系统。中国具有一个非常有实力的卫星发射工业，有可能帮助发射伽利略卫星。

51C该段主要是说，中国将帮助欧洲建立一个全球卫星导航系统。因此，作者整段使用了将来时。

52 A fund的意思是：to furnish a fund for(为……提供资金)。该句说，中国将提供二亿三千万欧元(二亿五千九百万美元)的资金。C和D在意思上不符合段意。

53 C A是错误的选项，因为伽利略(人造卫星)本身就是the major world infrastructure for the growing market for location services。B和D与句意不符。

54 D was also announced是被动语态，其后是动作的执行者the European Commission, the European Space Agency(ESA)和the Chinese Ministry of Science and Technology，所以应选择D。

55B这个句子的动词was also announced是过去时，句子的意思是说，前不久，欧洲贸易委员会、欧洲航天局和中国科技部宣布成立一个新的中心，来协调合作事宜。因此，B 是正确选项。A是错误选项，因为，虽然before也有与ago相同的意思，但是在用法上不一样,before与过去完成时一起使用。

56D整个句子的意思是说该中心将设在北京大学内。be located at(或in)是正确搭配。

57 A interfere with是固定搭配，在这里的意思是：妨碍，干扰。

58C这个句子说，美国对伽利略(人造卫星)持反对态度，是由于伽利略(人造卫星)对全嘲定位系统在商业上具有挑战性。选项A、B和D的意思都是“导致”，所以不符合句意。Be due to的意思是“由于”或“由……造成”。

59B这个句子告诉我们伽利略人造卫星群由27个运作卫星和3个储备卫星构成。B 是“由……构成”的意思。选项A的be made from是“由……材料制造”的意思。选项C的consist in是“在于”或“存在于”的意思。consist of不能使用被动形式，所以选项D也是错误的。

60D这个句子告诉读者，整个工程预计花费(cost)约32亿欧元。B和C与句意不符。选项A中的spend的意思是：to pay out(money)(花钱)，一般用作及物动词，如：He spent 5 yuan on the book.而cost作为动词的用法一般是：The book costs him 5 yuan.The book costs 5 yuan.动词cost也没有被动态形式。

61 B wide—band signal called the Public Regulated Service(PRS)叫做公共调控服务系统的宽带信号。called在此是过去分词作后置定语修饰wide—band signal。

62A句子的谓语动词have said决定了主语应该是人而不是物。B是单数名词，不能用在这里。

63 B Clocks on board the satellite：在这架卫星上的钟表。这里的satellite特指前一句中的The first Galile0，所以使用了定冠词the。选项A、C和D的内容文中都没有出现过，所以是错的。

64D通篇文章谈的都是定位系统，所以，地面接收借助定位系统来定位，应选location。其他三个选项(speed、direction、distance)都不符合上下文所表达的意思。

65B从语法结构来看，只能选择B，因为be relayed前没有动词不定式的形态标记to。
