第三篇" Salty" Rice Plant Boosts Harvests British 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 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. 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 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 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 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 slat and store what they do absorb 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 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. Which of the following statements about Flowers and Yeo is true（）
Passage 2 Questions 6 to 10 are based on the following passage:(77) Much unfriendly feeling towards computers has been based on the fear of widespread unemployment resulting from their introduction. Computers are often used as part of automated (自动化) production systems requiring a least possible number of operators, causing the loss of many jobs. This has happened, for example, in many steelworks.On the other hand, computers do create jobs. They are more skilled and better paid, though fewer in number than those they replace. Many activities could not continue in their present form without computers, no matter how many people are employed. Examples are the check clearing (交换) system of major banks and the weather forecasting system.When a firm introduces computers, a few people are usually employed in key posts (such as jobs of operations managers) while other staff are re-trained as operators, programmers, and data preparation staff. (78) After the new system has settled down, people in non-computer jobs are not always replaced when they leave, resulting in a decrease in the number of employees. This decrease is sometimes balanced by a substantial increase in the activity of the firm, resulting from the introduction of computers.The attitudes of workers towards computers vary. There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult.On the other hand, many workers regard the trend toward wider use of computers inevitable. They realize that computers bring about greater efficiency and productivity, which will improve the condition of the whole economy, and lead to the creation of more jobs. This view was supported by the former British Prime Minister, James Callaghan in 1979, when he made the point that new technologies hold the key to increased productivity, which will benefit the economy in the long run. According to the passage, what results from the introduction of computers（）
第二篇Teaching poetry No poem should ever be discussed or "analyzed", until it has been read aloud by someone, teacher or student. Better still, perhaps, is the practice of reading it twice, once at the beginning of the discussion and once at the end, so the sound of the poem is the last thing one hears of it. All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling "interpretation" of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching can not replace the student and teacher reading it or, best of all, reciting(背诵) it. I have come to think, in fact, that time spent reading a poem aloud is much more important than "analyzing" it, if there isn’t time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is " a criticism of life", and " a heightening(提升) of life". It is "an approach to the truth of feeling", and it " can save your life". It also deserves a place in the teaching of language and literature more central than it presently occupies. I am not saying that every English teacher must teach poetry. Those who don’t like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few thing s about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it. To have a better understanding of a poem, one should（）
