7、ir country will disappear from the face of the earthliterally. Several times this year, the Pacific island nation has been flooded by a sudden high tide. These tides, which swept across the island and destroyed houses, came when there was neither wind nor rain. “This never happened before,“ say the

8、older citizens of Kiribati.What is causing these mysterious high tides? The answer may well be global warming. When fuels like oil and coal are being burned, pollutants (污染物) are released; these pollutants trap heat in the earths atmosphere. Warmer temperatures cause water to expand and also create

9、more water by melting glaciers (冰川) and polar (极地的) ice caps.If the trend continues, scientists say, many countries will suffer. Bangladesh, for example, might lose one-fifth of its land. The coral (珊瑚) island nations of the Pacific, like Kiribati and the Marshall Islands, however, would face an eve

10、n worse fatethey would be swallowed by the sea. The loss of these coral islands would be everyones loss. Coral formations are home to more species than any other place on earth.The people of these nations feel frustrated. The sea, on which their economies have always been based, is suddenly threaten

11、ing their existence. They dont have the money for expensive technological solutions like seawalls. And they have no control over the pollutants, which are being released mainly by activities in large industrialized countries. All they can do is to hope that industrialized countries will take steps t

Studies of robots, particularly computer control software, are cons

16、idered to be generally less advanced in Japan than in America or Europe.2Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray- painting and assembling components.3In Britain, robot s

17、ales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.

18、4It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.5It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published i

19、n Japan.6The reliability of robots is measured in their M.T.B.F. or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test eve

20、ry single component they buy, instead of the normal procedure of just testing a small sample.7The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. Once programmed, the robots can work more accurately and consistently than humans, who c

The original chocolate drink was ma

24、de from the seeds of the cocoa tree (可可树) by South American Indians. The Spanish introduced it to the rest of the world during the 1500s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still

25、 exist today.The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “Potato Famine (饥荒)“ of 1845-1846, and thousands more

26、were forced to leave their homeland and move to America.There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the worlds largest grower of coffee, and coffee is an important crop in Colombia and other South Am

27、erican countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400s.According to an Arabic legend, coffee was discovered when aperson named Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and expe

Now,

32、 in test flights over the Rocky Mountains, NASA(美国航空航天局) engineers have successfully detected clear-air turbulence up to 10 seconds before an aircraft hits it.Clear-air turbulence often catches pilots by surprise. Invisible to radar, it is difficult to forecast and can hurl (用力抛出去) passengers about

33、the cabin. In December 1997, one passenger died and a hundred others were injured when unexpected rough air caused a United Airlines flight over the Pacific to drop 300 metres in a few seconds.However, passengers can avoid serious injury by fastening their seatbelts. “It is the only antidote (对策) fo

34、r this sort of thing,“ says Rod Bogue, project manager at NASAs Dryden Flight Research Center in Edwards, California.The centres new turbulence detector is based on lidar, or laser radar. Laser pulses are sent ahead of the plane and these are then reflected back by particles in the air. The techniqu

35、e depends on the Doppler effect. The wavelength of the light shifts according to the speed at which the particles are approaching. In calm air, the speed equals the planes airspeed. But as the particles swirl (打漩) in rough air, their speed of approach increases or decreases rapidly. The rate of chan

36、ge in speed corresponds to the severity (激烈程度) of the turbulence.In a series of tests that began last month, a research jet flew repeatedly into disturbed air over the mountain ridges (山脉) near Pueblo, Colorado. The lidar detector spotted turbulence between 3 and 8 kilometres ahead, and its forecast

37、s of strength and duration corresponded closely with the turbulence that the plane encountered.Bogue says that he had “a comfortable amount of time“ to fasten his seatbelt. The researchers are planning to improve the lidars range with a more powerful beam. The system could be installed on commercial

38、 aircraft in the next few years.（分数：15.00）(1).What does “clear-air turbulence“ probably mean? (Paragraph 1)AA not very rough storm.BUnexpected disturbed air.CA kind of visible storm.DA storm over mountain ridges.（分数：3.00）A.B.C.D.(2).In December 1997, a United Airlines flight hit unexpected rough air

40、ight.Cthe number of particles in the air.Dthe changes of the particles speed.（分数：3.00）A.B.C.D.(4).We can infer from the fifth paragraph thatAthe lidar detector can successfully forecast turbulence.Bresearchers are not sure about the effectiveness of the lidar detector.Cpassenger planes will be used

41、in further experiments.Dno more test flights are needed.（分数：3.00）A.B.C.D.(5).The last paragraph tells us, among other things, thatAthe lidar detector needs improvement.Bmany airlines are interested in the system.Cpassengers often forget to fasten their seatbelts.Dthe lidar detector can be used in a

42、wide range of areas.（分数：3.00）A.B.C.D.七、第三篇(总题数：1，分数：15.00)“Salty“ Rice Plant Boosts HarvestsBritish scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more.Tim Flowers and To

43、ny Yeo, from Sussex Universitys School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty.The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council,

44、 to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice.It is estimated that each year more than 10m hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长) plants. The problem

45、is caused by several factors. In the tropics, mangroves (绿树林) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation of

46、ten causes problems when water is evaporated (蒸发) by the heat, leaving salt deposits behind.Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive.To overcome these problems, Flower

47、s and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells but do not affect the plants growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be con

48、sidered for commercial use.Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer countries of the world.（分数：15.00）(1).Which of the following statements about Flowers and Yeo is true?AThey are students at Sussex University.BThey are rice breeders.CThey are husband and wife.DThey are colleagues at an institution of higher learning.（分数：3.00）A.B.C
