26、s 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 how crops, such as rice, could be made to grow in wat

27、er that has become salty. The pair have recendy 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 estim

28、ated 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 traditionally formed barriers to sea water have been cut d

29、own. 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 salt then enters the plants and prevents them

30、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 litde salt and store what they do absorb in cells that do not affect the plants growth.

31、 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 and Yeo will try to breed the appropriate genes

32、 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. 31 Which of the following statements about Flowers and Yeo is true? （ A） They are students at Sussex University. （ B） They

33、are rice breeders. （ C） They are husband and wife. （ D） They are colleagues at an institution of higher learning. 32 Flowers and Yeo have started a program_. （ 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 sal

34、ty （ D） to find ways to remove excessive salt from soil 33 Which of the following is NOT mentioned as a cause of the problem discussed in the passage? （ A） Natural barriers to sea water have been destroyed. （ B） The water table has gone down after droughts. （ C） Sea level has been continuously risin

35、g. （ D） Evaporation of water leaves salt behind. 34 The word “ affect“ in Paragraph 6 could be best replaced by_. （ A） influence （ B） effect （ C） stop （ D） present 35 The attitude of the author towards the research project is_. （ A） positive （ B） negative （ C） suspicious （ D） indifferent 35 The firs

36、t navigational lights in the New World were probably lanterns hung at harbor entrances. The first lighthouse was put up by the Massachusetts Bay Colony in 1716 on Little Brewster Island at the entrance to Boston Harbor. Paid for and maintained by “light dues“ levied (征收 ) on ships, the original beac

37、on was blown up in 1776. Until then there were only a dozen or so true lighthouses in the colonies. Litde over a century later, there were 700 lighthouses. The first eight lighthouses erected on the West Coast in the 1850s featured the same basic New England design:a Cape Cod dwelling with the tower

38、 rising from the center or standing close by. In New England and elsewhere, though, lighthouses reflected a variety of architectural styles. Since most stations in the Northeast were set up on rocky eminences (高处 ), enormous towers were not the rule. Some were made of stone and brick, others of wood

39、 or metal. Some stood on pilings or stilts; some were fastened to rock with iron rods. Farther south, from Maryland through the Florida Keys, the coast was low and sandy. It was often necessary to build tall towers there massive structures like the majestic lighthouse in Cape Hatteras, North Carolin

40、a, which was lit in 1870. 190 feet high, it is the tallest brick lighthouse in the country. Not withstanding differences in construction appearance, most lighthouses in America shared several features: a light, living quarters, and sometimes a bell (or, later, a foghorn). They also had something els

41、e in common: a keeper and usually the keepers family. The keepers essential task was trimming the lantern wick (灯芯 ) in order to maintain a steady, bright flame. The earliest keepers came from every walk of life, they were seamen, farmers, mechanics, rough mill hands and appointments were often hand

42、ed out by local customs commissioners as political plums. After the administration of lighthouse was taken over in 1852 by the United States Lighthouse Board, and agency of the Treasury Department, the keeper corps gradually became highly professional. 36 Which is the best title for the passage? （ A

43、） The Lighthouse on Little Brewster Island. （ B） The Life of a Lighthouse Keeper. （ C） Early Lighthouses in the United States. （ D） The Modern Profession of Lighthouse-keeping. 37 Why does the author mention the Massachusetts Bay Colony? （ A） It was the headquarters of the United States Lighthouse B

44、oard. （ B） Many of the tallest lighthouses were built there. （ C） The first lantern wicks were developed there. （ D） The first lighthouse in North America was built there. 38 It can be inferred from the passage that lighthouses in the Northeast did NOT need high towers because_. （ A） ships there had

45、 high masts （ B） coastal waters were safe （ C） the coast was straight and unobstructed （ D） the lighthouses were built on high places 39 According to the passage, where can the tallest brick lighthouse in the United States be found? （ A） Little Brewster Island. （ B） The Florida Keys. （ C） Cape Hatte

46、ras. （ D） Cape Cod. 40 We can know from the passage that the coast of North Carolina is_. （ A） rocky eminences （ B） high and flat （ C） low and sandy （ D） high and sandy 40 The Gene Industry Major companies are already in pursuit of commercial applications of the new biology. They dream of placing en

47、zymes (霉 ) in the automobile to monitor exhausts and send data on pollution to a microprocessor (微处理机 ) that will then adjust the engine. They speak of what the New York Times calls “metal-hungry microbes(渴望吃金属的微生物 ) that might be used to mine valuable trace metals from ocean water“. They have alrea

48、dy demanded and won the right to patent new lifeforms. Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry jn the entire biotechnological(生物工艺学 ) field. They create images not of oil spills, but of “ microbe spills “ that c

49、ould spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination.Should we breed people with cow-like stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain? Should
