Genetically modified maize (玉米) could mean extinction for this beautiful butterfly, Rafael Ruiz reports. A

8、lthough its body is about 3 cm long and it only weighs 1 gin, the Monarch butterfly manages to travel 5,000 km each year. It seems to be so fragile, but its long journeys are proof of its amazing ability to survive. This autumn, the Monarch butterfly will once more set out on its journey from the U.

9、 S. It will keep going until it reaches Mexico. It travels these huge distances to escape the cold weather in the north. In November, millions of Monarchs fall like bright, golden rain onto the forests in the mountains of central Mexico. In the silence of these mountains you can hear a strange flapp

10、ing (拍动) of wings, as the Monarchs arrive at their destination. In the mountains, which reach a height of 3,000 meters, the butterflies are safe. Before reaching their journey“s end they have faced strong winds, rain and snowstorms and they do not all manage to reach their destination. When the wint

11、ers are really bad, perhaps 70 per cent of them will not survive. Their long journey to Mexico is thought to be one of the most amazing events in the whole of the American continent. When they get there they will stay until the beginning of April, when their internal calendar tells them that it is t

12、ime to go back. The long journey, with all its dangers, begins again. These delicate creatures now face danger of another kindfrom scientific progress. In the U. S., millions of farms grow genetically modified maize which is pure poison for the butterfly. Laboratory experiments have shown that half

13、of the butterflies which feed on the leaves of genetically modified maize die within 48 hours. Not all experts agree that this variety of maize is responsible for the threat to the Monarchs. In spite of these doubts, the European Union has refused to approve new crops of genetically modified maize u

14、ntil further investigations have been carried out. Greenpeace is campaigning against genetically modified products (in Spain, there are already 20,000 hectares of modified maize ). The environmental organization recently published a list of 100 species of butterfly in Europe alone which are threaten

It took Cope 30 years to develop the sof

18、tware. Now most people can“t tell the difference between music by the famous German composer J. S. Bach (16851750) and the Bach-like compositions from Cope“s computer. 2 It all started in 1980 in the United States, when Cope was trying to write an opera. He was having trouble thinking of new melodie

19、s, so he wrote a computer program to create the melodies. At first this music was not easy to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers“ brains work like big databases. First, they take in all the music that they have ever heard. Then

20、 they take out the music that they dislike. Finally, they make new music from what is left. According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it. 3 Cope built a huge database of existing music. He began with hundre

21、ds of works by Bach. The software analyzed the data: it broke it down into smaller pieces and looked for patterns. It then combined the pieces into new patterns. Before long, the program could compose short Bach-like works. They weren“t good, but it was a start. 4 Cope knew he had more work to dohe

22、had a whole opera to write. He continued to improve the software. Soon it could analyze more complex music. He also added many other composers, including his own work, to the database. 5 A few years later, Cope“s computer program, called “Emmy“, was ready to help him with his opera. The process requ

23、ired a lot of collaboration between the composer and Emmy. Cope listened to the computer“s musical ideas and used the ones that he liked. With Emmy, the opera took only two weeks to finish. It was called Cradle Falling , and it was a great success ! Cope received some of the best reviews of his care

24、er, but no one knew exactly how he had composed the work. 6 Since that first opera, Emmy has written thousands of compositions. Cope still gives Emmy feedback on what he likes and doesn“t like of her music, but she is doing most of the hard work of composing these days!（分数：8.00）(1).Paragraph 2 1 A.

28、al, carrying over traditional designs that went back to the Middle Ages. During the first half of the eighteenth century, however, houses began to show a new elegance. As wealth increased, more and more colonists built fine houses. Since architecture was not yet a specialized profession in the colon

29、ies, the design of buildings was left to carpenters who undertook to interpret architectural manuals imported from England. There are an astonishing number of these handbooks for builders in colonial libraries, and the houses erected during the eighteenth century show their influence. Most domestic

30、architecture of the first three-quarters of the eighteenth century displayed a wide range of taste and freedom of application of the rules laid down in these books. Increasing wealth throughout the colonies resulted in houses of improved design, whether the material was wood, stone or brick. New Eng

31、land still favored wood, though brick houses became common in Boston and other towns, where the danger of fire forced people to use more durable material. A few houses in New England were built of stone, but only in Pennsylvania and its neighboring areas was stone widely used in dwellings. An increa

32、sed use of bricks is noticeable in Virginia and Maryland, but wood remained the most popular material even in houses built by wealthy landowners. In the Carolinas, even in the crowded town of Charleston, wooden houses were much more common than brick houses. Eighteenth-century houses showed great in

33、terior improvements over their predecessors. Windows were made larger and shutters (百叶窗) removed. Large, clear panes (玻璃窗) replaced the gray glass of the seventeenth century. Doorways were larger and more decorative. Fireplaces became decorative features of rooms. Walls were sometimes elaborately de

34、corated. White paint began to take the place of blue, yellow, green and gray colors, which had been popular for walls in the earlier years. After about 1730, advertisements for wallpaper styles in scenic patterns began to appear in colonial newspapers.（分数：15.00）(1).What does the passage mainly discu

39、 in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from Sussex University“s 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.

40、The pair has 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 year more t

41、han 10 million 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 (红树木) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterrane

42、an, 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. Hea

43、vy 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

44、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

45、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 bre

46、eders.C.They are husband and wife.D.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 pollutionB.to identify genes that promote growth in salty soilC.to breed rice plants that taste saltyD.to find ways to

47、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.B.The water table has gone down after droughts.C.Sea level has been continuously rising.D.Evaporation of water le

48、aves salt behind.(4).The word “affect“ in Paragraph 6 could be best replaced by _.（分数：3.00）A.influenceB.effectC.stopD.present(5).The attitude of the author towards the research project is _.（分数：3.00）A.positiveB.negativeC.suspiciousD.indifferent七、第三篇(总题数：1，分数：15.00)TransportationFor many years in the

49、 desert, camels used to be the only form of transportation (运输). Before the age of modern trains, camel trains were used to carry all the goods for trading between Central Africa and Europe. Traders sometimes put together camel trains with 10,000 to 15,000 animals. Each animal often carried as much as 400 pounds and could travel twenty miles a day. This form of transportation used to be so important that camels were called “ships of the desert“. Now modem trains travel across the desert in a very short time. One engine can pull as much weight as 135,000 camels. In a
