7、country will disappear from the face of the earth - literally. 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 fate - they 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 threa

Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.2 Although industrial robots were originally developed as de

17、vices 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. This is partly because British wage rates are too low to mak

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 MT.

One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small sample.7 The biggest single benefit of intr

In London, shops where chocolate drinks were served became important meeting places. Some still exist today;The potato is also f

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 mere were forced to leave their homela

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 nativ

Now, in test flights over the Rocky Mountains, NASA (美国航空航天局) engineers ha

33、ve 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 the cabin. In December 1997, one passenger died and a hundred others

34、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) for this sort of thing,“ says Rod Bogue, project manager at NASAs Dryde

35、n 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 technique depends on the Doppler effect. The wavelength of the light shifts a

36、ccording 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 change in speed corresponds to the severity (激烈程度) of the turbulence.In a

37、 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 forecasts of strength and duration corresponded closely with the turbulence t

38、hat 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 aircraft in the next few years.（分数：15.00）(1).What does “clear-air tu

43、 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 Tony Yeo, from Sussex Universitys School of Biological Sciences, have spent several years researching

44、 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, to establish which genes enable some plants to survive salty conditions. The aim is to breed this

45、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 is caused by several factors. In the tropics, mangroves (红树林) that create swamps (沼泽) and tradition

46、ally 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 often causes problems when water is evaporated (蒸发) by the heat, leaving salt deposits behind.Excess

47、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, Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb

48、in cells that 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 considered for commercial use.Once the characteristics for surviving salty soil are known, Flowers an

49、d 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?（分数：3.00）A.T
