问答题Britain's Cabinet Office released a sweeping report on the country's food policy, and determined that Britons are wasting too much food. A third of the food bought for home consumption is wasted- 6.7 million tonnes. Most of this could have been eaten. Wasting food costs the average UK family £420 a year. Eliminating the unnecessary greenhouse gas emissions that this wasted food produces would be equivalent to taking one in five cars off UK roads. By using 60% of food thrown away by households, enough energy could be generated to provide power for all the homes in Glasgow and Edinburgh. This waste is adding to the rise in food prices, the report said, in a world where food output must rise dramatically. The report notes that, according to a report by the World Bank, cereal production needs to increase by 50 percent and meat production 80 percent between 2000 and 2030 to meet global demand. The report noted that food waste contributes to greenhouse emissions, partly because rotting food in landfills generates methane, a powerful greenhouse gas. The report also said that, because of problems with storage or distribution, as much as 40 percent of food harvested in the developing world is wasted before it reaches the plate. In the foreword to the report, Prime Minister Gordon Brown said that food waste is a global problem. Recent food price rises are a powerful reminder that access to ever more affordable food cannot be taken for granted, and it is the family finances of the poorest in our society that are hit hardest when food prices increase. But the principal food security challenge for the UK is a global one. We cannot deal with higher food prices in the UK in isolation from higher prices around the world- attempting to pursue national food security in isolation from the global context is unlikely to be practicable, sustainable or financially rational. Americans do not seem to be doing much better at conserving food than their counterparts across the Atlantic. Last month, The New York Times cited a 1997 study from the U.S. Department of Agriculture that found that Americans discard an estimated 27 percent of the food available for consumption, about a pound per day per person.

问答题{{U}}Technology has made it easy to cross national frontiers physically, but there has been no invention of new mental habits to enable people to cope with foreigners in a new way{{/U}}. For that to happen, the habits of tourists will have to alter. The hidden god of travel is still Karl Baedeker, even though he died in 1859. His guidebooks have a permanent pattern, making travel essentially a matter of sightseeing, looking at places rather than at people. (47) {{U}}His achievement was to find sights that could be guaranteed to be there all the time, to be clearly identifiable, dated and classified according to the amount of admiration they deserved{{/U}}. He made visits to old monuments and to art museums--the staple diet of the traveler, drawing attention away from the living inhabitants. To this day, tourism is a course in history, architecture, aesthetics, and the appreciation of hotels and food. (48) {{U}}The cult of "sights" has grown so much that most foreign (organized) travel involves virtually no contact with the natives, beyond those who specialize in catering for tourists{{/U}}. The business traveler tends to meet mainly people in his own profession. How different from the itinerary of a modern package holiday is this program, drawn up by an Englishman, Sir Francis Head, in 1852, before the guide books told tourists what to do. In Paris, he visited the municipal pawnshop, the asylum for blind youths, where Braille, still unknown in England, was being used, a prison, an orphanage for abandoned children, the Salpetriere old people's home, the morgue, the national printing works, the military academy, the national assembly, the public laundry, and finally he attended/he lectures at the Conservatory for Arts and Crafts. The rise of bureaucratic officialdom soon stopped that kind of curiosity; but perhaps today a new openness will allow it to express itself again. In former times, the attraction of foreign travel was often that people did abroad what they dared not do at home, which is shy foreign countries won reputations for sexual debauchery. (The French considered England as debauched as the English visitors to the Folies Bergeres imagined the French to be. ) (49) {{U}}But now that a visit to France is no longer a dangerous adventure, and that an international uniformity exists in so many of the goods and facilities the tourist encounters, where is the excitement, and where are the new discoveries?{{/U}} It is to be found in the people. (50) {{U}}The foreignness in foreign travel today must come mainly from meeting individuals whom one would not normally meet at home.{{/U}}

问答题Please read the following article in Chinese carefully, and then write a summary of 200 words in English on the ANSWER SHEET. Make sure that you cover all the major points of the article. 护士在糖尿病护理中既可以发挥专家的作用,也可以只承担其中的部分护理工作。不管是何种场所的护理,都应强调病人的自我护理。 自我护理是处理糖尿病的关键,开始得越早越好。不过,当糖尿病患者确实需要帮助时,就必须由知识丰富的专业健康人士提供。 传统上,英国的糖尿病教育是由糖尿病专科护理师承担的,他们还承担着其他临床、治疗和研究工作。有些教育是以一对一方式进行,但健康专业人士已逐渐认识到,糖尿病患者互相间也能学到很多东西,因此,小组教育已经成为一种标准,还可以邀请同伴或家人参加。邀请家庭食品采购和烹制人员加入教育也很重要。他可能是家庭成员之一,也可能是家务女工或疗养院护理员。 随着社区内糖尿病人数的增加,执业护士和地区护士已经承担了过去由糖尿病护理专家所从事的很多工作。因此,他们也将参与糖尿病教育的计划和实施。今天,由于糖尿病护理专家都是在医院工作,很多糖尿病患者,特别是二型糖尿病患者,都看不到这些护理专家。 当今技术的发展,使人们的健康咨询方式发生了很大变化。电话或英特网已经成为获取健康信息的常用手段。结果,越来越多的人开始求助于拥有有用(有时也是令人迷惑)信息的健康专业人士,他们的信息或来自上述渠道,或者来自电台、电视和朋友。伯明翰正在尝试举办数字电视互动式健康咨询节目,一些健康促进机构已经接触这些屏幕节目和互动CD光盘。 这都为病人提供了更多的选择,应该受到欢迎。这可能意味着,护士的角色将发生变化,她们将不再是第一个提供信息的人,新的重要角色将出现,包括解释信息对个人及其朋友和亲属的意义,创办论坛,讨论如何实施建议。 护理糖尿病患者的护士必须有共同的工作目标,因此,制订目标和决定病情优先处理顺序便成为护理的重要因素。研究表明,糖尿病并发症可以预防。如果确实出现并发症,其恶化进程也可以减缓。关键是要控制血糖。 一型糖尿病患者的糖化血红蛋白目标是7.5%,二型为低于7%。血压是导致糖尿病并发症的一个因素,两种糖尿病的血压都应低于140/80mmHg,且越低越好。当然应以不出现低血压症状为宜。

问答题{{B}}Directions:{{/B}} Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on Answer Sheet 2. Stephen M. Saland, chairman of the State Senate Education Committee, is a conservative upstate Republican, and Steven Sanders, chairman of the Assembly Education Committee, is a liberal New York City Democrat. But when it comes to education, they have much in common. Neither is a fan of the federal No Child Left Behind Law and its extensive testing mandates. Both say that standardized tests are too dominant in public schools today. That has at times put the two education chairmen in conflict with the state education commissioner, Richard P. Mills. (46) {{U}}During his 10 year tenure, Dr. Mills has turned New York into one of the most test-driven public systems in the nation, requiring students to pass five state tests to graduate.{{/U}} (47) {{U}}For months now, the legislative leaders and the commissioner have been locked in a little-noticed fight over the future of 28 small alternative public high schools, a fight that may well be the final stand for opponents of standardized testing in New York.{{/U}} Senator Saland and Assemblyman Sanders are doing their best to protect these schools in New York City (Urban Academy, Manhattan International), Ithaca (Lehman Alternative) and Rochester (School Without Walls) and help them retain their distinctive educational approach. (48) {{U}}Instead of the standard survey courses in global studies, American history, biology and chemistry pegged to state tests, these schools favor courses that go into more depth on narrower topics. {{/U}}At Urban Academy, there are courses in Middle East conflicts, world religions, post-Civil War Reconstruction and microbiology. In the mid-1990's, the former education commissioner, Thomas Sobol, granted these 28 consortium schools (serving 16,000 students, about 1 percent of New York's high school population) an exemption from most state tests. That permitted a more innovative curriculum, and students were evaluated via a portfolio system that relies on research papers and science projects reviewed by outside experts like David S. Thaler, a Rockefeller University microbiology professor, and Eric Foner, a Columbia history professor. The Gates Foundation, which has given hundreds of millions of dollars to start small high schools nationwide, is so impressed with these schools, and it regularly sends educators to New York to see how they're run. But the testing exemption for these schools is about to expire, and Commissioner Mills does not want it renewed. He believes that all students, without exception, should take every test. Recently, Senator Saland defied the commissioner. He shepherded a bill through the Republican controlled Senate that passed 50 to 10 and would continue these schools' waivers for four years. (49) {{U}}Senator Saland's bill does require that students pass the state English and math tests to graduate, letting the state gauge the alternative schools' performance versus mainstream schools.{{/U}} On the Senate floor, Senator Sa[and noted that while 61 percent of consortium students qualified for free lunches and three quarters were black or Hispanic, 88 percent went on to college, compared with 70 percent at mainstream schools that give state tests. (50) {{U}}He said that the dropout rate was half the rate at mainstream schools and that on the one statewide test these students took regularly, English, they scored an average of 77, outdoing mainstream students by 5 points.{{/U}}

问答题The sun heats the Earth's surface unevenly causing differences in air pressure. It's these differences that cause wind to flow over our planet's surface. Scientists convert wind energy into electrical energy by using wind mills or wind turbines. The turbines take the movement of the air and convert it into mechanical energy. Each wind mill contains blades that are connected to a generator. The faster the blades spin the more energy that is produced by the generator. In areas that have constant winds, you will find wind farms and small, wind-driven generators. On these wind farms are hundreds of wind turbines capable of providing the electricity for entire communities. The small wind-driven generators are used for individual homes to produce electricity. Similar to solar energy, wind energy cannot be consistently used. There are areas around the world that do not have constant winds. In areas like windy mountain passes, the wind does not blow continuously. Therefore wind energy is only dependable for certain areas of the planet.

问答题In politics, in the courts, even on the ubiquitous TV talk shows, it is good form to pick an intellectual fight. People attach each other--hurl insults, even-and it counts as logical argument. I cannot understand it. {{U}}(1) It seems that our society favors a kind of ritualized aggression. Everywhere you look, in newspapers and on television, issues are presented using the terminology of war and conflict. We hear of battles duels (决斗) and disputes. We see things in terms of winners and losers, victors and victims.{{/U}} {{U}}(2) The problem is society's unquestioning belief in the advantages of the debate as a way of solving disagreements, even proving right from wrong. Our brainwashing begins early at school, When the brightest pupils are co-opted onto the debating system. {{/U}}They get there because they can think up a good argument go support their case. once on the debate team, they learn that they earn bonus points for the skill with which they verbally attack, or insult, the opposing team.{{U}} (3) They win if they can successfully convince the audience that they are right, even if the case they are arguing is clearly non-sensual. They do this by proving themselves to be stronger, brighter, more outrageous, even.{{/U}} The training in this adversarial approach continues at out tertiary institutions. The standard way to present an academic paper, for instance, is to take up an opposing argument to something expressed by another academic. The paper must set out to prove the other person wrong. This is not at all the same thing as reading the original paper with an open mind and discovering that you disagree with it. The reverence for the adversarial approach spills over into all areas of life. Instead of answering their critics, politicians learn to sidestep negative comments and turn the point around to an attack on accusers. Defense lawyers argue the case for their clients event when they suspect they may be guilty. And ordinary people use the came tactics--just listen to your teenager next time you pull him up for coming home late. You can be sure a stream of abuse will flow about your own time-keeping, your irritating habits, your history of bad parenting.

问答题 Wiping away doubts that Dolly the sheep clone was a fluke, University of Hawaii researchers announced they've been cloning mice for months, creating a flock of more than 50 duplicate rodents along the way. 71. {{U}}The success of the Hawaii group transforms adult cloning from a scientific novelty to a well-defined procedure likely to be .reproduced in labs around the world. The mass production of carbon copy mice, in turn, now allows researchers to test variations of the cloning techniques to see what works best.{{/U}} Cloning the genetically engineered mice used in medical studies should also be cheaper than current breeding methods. The Hawaii researchers use essentially the same recipe used to make Dolly: Take an egg. Scoop out the nucleus, which contains the DNA genetic information, and discard. Take a cell of the animal you wish to clone and insert its DNA into the egg. Add chemicals to tell the egg to start developing into an embryo. Incubate the embryo in a test tube for a few days, and then implant it into a foster mother. Wait for the foster mother to give birth to the clone. 72. {{U}}Where they modified the recipe was the method for moving the DNA from the animal-to-be-cloned into the egg. Most researchers had thought that mice would be particularly difficult to clone, because the DNA in mice embryos switches on very early, possibly as soon as the egg splits into the two-cell stage{{/U}}. Because adult cells have specific, specialized functions, most of the unused DNA has been turned off. Scientists had thought that the implanted DNA would not have enough time to "repro- gram" itself back to the embryonic, unspecialized state. Thus, most cloning research has focused on animals where the DNA switches on later, allowing more time for the reprogramming. 73. {{U}}In cows, for example, the DNA switch-on occurs when the embryo reaches the eight-cell stage. No one is sure how the ttawaii group got the mouse DNA to reprogram itself more quickly, but some have the suspicion that getting rid of the outer part of the adult cell speeds the process.{{/U}} In addition to various genetic tests, the researchers used a simple color scheme to verify that the DNA of the babies was not contaminated by either the egg donor or the foster mother. The eggs came from black mice, while the foster mothers were all white mice. The baby mice all came out coffee-colored, the color of their identical DNA mother. The researchers have licensed their technology to venture capital company ProBio America Inc. , based in Honolulu. "This technique we are expanding into the large commercial animals, such as cows and sheep, where much of our business is intended to be," says ProBio's Cameron Reynolds.
