7、ly. 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 older citizens of Kiribati. What is causing these mysteriou

8、s 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 more water by melting glaciers (冰川 )and polar (极地的) ice cap

9、s. 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 even worse fate they would be swallowed by the sea. The loss

10、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 threatening their existence. They dont have the money for expens

11、ive 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 to reduce pollution. （分数：7.00）(1).The people of Kiribati

15、题数：1，分数：8.00)Robots 1 The most sophisticated(先进的)Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe. 2

16、 Although 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. 3 In Britain, robot sales appropriately peaked in 1984, but have been declining ever since.

17、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. 4 It has been calculated that a robot uses on average about 100 times

18、more energy than a human to do an equivalent job. 5 It 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 in Japan. 6 The reliability of robots is measured in their M.T.B.F.

19、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 every single component they buy, instead of the normal procedure of

20、just testing a small sample. 7 The 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 can get tired and bored. A Ongoing Research B Extension of Use C

23、一篇 New Foods and the New World In the last 500 years, nothing about people not their clothes, ideas, or languages has changed as much as what they eat. The original chocolate drink was made from the seeds of the coca tree (可可树)by South American Indians. The Spanish introduced it to the rest of the w

24、orld 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 exist today. The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where

25、 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 were forced to leave their homeland and move to America. There are many other foods that have traveled from South A

26、merica 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 American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arab during

27、 the 1400s. According to an Arabic legend, coffee was discovered when a person name Kaldi noticed that his goats were attracted to the red berries on a coffee bush. He tried one and experienced the “wide-awake” feeling that one-third of the worlds population now starts the day with. （分数：15.00）(1).Ac

31、n keep one awake.D.Coffee drinks were first made by Arabs.第二篇 Please Fasten Your Seatbelts Severe turbulence (湍流) can kill aircraft passengers. Now, 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

32、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 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 P

33、acific 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) for this sort of things,” says Rod Bogue, project manager at NASAs Dryden Flight Research Center in Edwards, California. The centres new turbulence det

34、ector 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 technique 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

35、 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 change 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 d

36、isturbed air over the mountain ridges (山脉) near Pueblo, Colorado. The lidar detector spotted turbulence between 3 and 8 kilometres ahead, and its forecasts of strength and duration corresponded closely with the turbulence that the plane encountered. Bogue says that he had “ a comfortable amount of t

37、ime” 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 aircraft in the next few years. （分数：15.00）(1).What does “clear-air turbulence” probably mean? (Paragraph 1) （分数：3.00）A.A not very rough storm.B

38、Unexpected disturbed air.C.A kind of visible storm.D.A storm over mountain ridges.(2). In December 1997, a United Airlines flight hit unexpected rough air, （分数：3.00）A.causing a lot of damage to the plane.B.throwing its passengers out of the cabin.C.resulting in heavy casualties.D.forcing the pilot

39、to make an emergency landing.(3). The turbulence detector can tell the severity of the turbulence by measuring （分数：3.00）A.the speed of the plane.B.the speed of the light.C.the number of particles in the air.D.the changes of the particles speed.(4).We can infer from the fifth paragraph that （分数：3.00）

40、A.the lidar detector can successfully forecast turbulence.B.researchers are not sure about the effectiveness of the lidar detector.C.passenger planes will be used in further experiments.D.no more test flights are needed.(5).The last paragraph tells us, among other things, that （分数：3.00）A.the lidar d

41、etector needs improvement.B.many airlines are interested in the system.C.passengers often forget to fasten their seatbelts.D.the lidar detector can be used in a wide range of areas.第三篇 “Salty” Rice Plant Boosts Harvests British scientists are breeding a new generation of rice plants that will be abl

42、e to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony 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

43、 salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, 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 ye

44、ar more than 100 hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长)plants. The problem is caused by several factors. In the tropics, mangroves (红树林) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterran

45、ean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. in Latin America, irrigation often 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. He

46、avy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants growth. They have started to b

47、reed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered 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 cr

48、ops 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? （分数：3.00）A.They are students at Sussex University.B.They are rice b

49、reeders.C.They are husband and wifeD.They are colleagues at an institution of higher learning.(2).Flowers and Yeo have started a programme （分数：3.00）A.to find ways to prevent water pollution.B.to identify genes that promote growth in salty soil.C.to breed rice plants that taste salty.D.to find ways to remove excessive salt from soil.(3).Which of the following is NOT mentioned as a cause of the problem discussed in the passage? （分数：3.00）A.Natural barriers to sea water have been destroyed.
