【文章內(nèi)容簡介】 ra, Xpu Ha beach boasts a subtle beach club atmosphere. Xpu Ha Beach isn’t as busy as Mamita’s beach club but it still possesses cool beach clubs, a rental shop and a hotel. someone has appreciation for caving adventures, he or she should go to . A. North Beach B. Xpu Ha Beach C. Wet n’ Wild Paterpark D. Playa Brujas of the following is true according to the passage? A. Playa Brujas is close to Mazatlan and lies along the east coast of Mexico B. North Beach is the finest beach in the Yucatan Peninsula for its private location C. Tourists can rent some equipment at Xpu Ha Beach, which is as busy as others D. When a couple choose a beach with children, Playa la Audiencia is their best choice B If two scientists at Los Alamos National Laboratory are correct, people will still be driving gasoline powered cars 50 years from now, giving out heattrapping carbon dioxide(二氧化碳 ) into the atmosphereand yet that carbon dioxide will not contribute to global warming. In a proposal by two scientists, vehicle emissions(排放 ) would no longer contribute to global warming. The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline. The idea is simple. Air would be blown over a liquid solution of potassium carbonate, which would absorb the carbon dioxide. The carbon dioxide would then be put to chemical reactions that would turn it into fuel(燃料 ): gasoline or jet fuel. This process could change carbon dioxide from an unwanted, climatechanging pollutant into a vast resource for renewable fuels. The cycleequal amounts of carbon dioxide produced and removedwould mean that cars, trucks and airplanes using the synthetic(合成的 ) fuels would no longer be contributing to global warming. Although they have not yet built a synthetic fuel factory, or even a small model, the scientists say it is all based on existing technology. “Everything in the concept has been built, is operating or has a close cousin that is operating.” Dr. Martin said. The Los Alamos proposal does not go against any laws of physics, and other scientists who have independently suggested similar ideas. Dr. Martin said he and Dr. Kubic had worked out their concept in more detail than former proposals. There is, however, a major fact that explains why no one has built a carbondioxidetogasoline factory: it requires a great deal of energy. According to their analysis, their concept, which would cost about $5 billion to build, could produce gasoline at an operating cost of $ a gallon and would turn economically practical when the price at the pump hits $ a gallon. Other scientists said the Los Alamos proposal perhaps looked promising but could not evaluate it fully because the details had not been published. “It’s definitely worth pursuing,” said Martin I. Hoffert, a professor of physics at New York University. “It’s not that new an idea. It has a couple of pieces to it that are interesting.” is the value of the scientists’ proposal? A. It increases the productivity of a fuel factory B. It decreases the cost of producing gasoline C. It reduces the pollution caused by car driving D. It promotes a new idea of environmental protection underlined part “has a close cousin that is operating” probably means the technology in the concept . A. has been popular for so long B. has been ignored by many people C. is not appropriate for practice D. will be put into practice in the near future is the biggest challenge in realizing the concept Green Freedom? A. There is no theoretical basis B. It is not economically practical C. There is no solution to some technical problems D. Only a few scientists support the idea C Why not write in a foreign language? If people feel free to choose their profession, their religion, and even their sex, why not just decide which language you want to write? Ever since Jhumpa published In Other Words in Italian, people have been asking me, “Why don’t you write in Italian, Tim? After all, you’ve been in the country 35 years. What keeps you tied to English?” Is it just a question of economic convenience? Certainly economics can be important. It was the factor that pushed Conrad to abandon his Polish mother tongue. If it is not possible to publish at home, or to publish there as one would wish to publish, then one is likely to go elsewhere. And if to publish elsewhere one has to change language, then some authors are willing to take that step. Something of the same logic has driven many writers from Africa, Asia to write in French and English in recent years. There is also the fact that people in Europe and the West are interested in the countries they grew up in. Just as in the nieenth century, novelists like Thomas Hardy could “sell” their familiarity with peasant life to a middleclass metropolitan public, so these writers have interested us with stories that might seem mon in their home countries. There is also a real internationalism in the decision to change language. If you have “a message” and if English is the language that offers maximum spread, then it would seem appropriate to use it. All these make sense. Critics tend to pay attention only to those who have made a success of writing in a new language. In April 2021, a New York Times article essentially listed young literary stars who had switched to writing in the main Western languages. At this point, the native English speaker almost begins to feel at a disadvantage for having been born into the dominant culture. Should we perhaps head for Paris, like Beckett or Jonathan Littell, just to be between two worlds? Or look for something more exotic(異國的 ) and have ourselves translated back into English afterward?
