20、ection you will hear everything ONCE ONLY. Listen carefully and then answer the questions that follow. At the end of each news item, you will be given 10 seconds to answer the questions. 1 【听力原文】 MIT chemistry professor Daniel Nocera leaded research on the artificial leaf project, says he and his co

21、lleagues took their cues from plants, which are literally buzzing with electricity. During photosynthesis, the energy in sunlight splits water molecules into hydrogen and oxygen. The hydrogen joins with carbon dioxide to make sugar, an essential fuel for plant growth. In Noceras laboratory, scientis

22、ts replicated that chemical process using a silicon device about the size and shape of a playing card, only thinner. Its coated with nickel and cobalt catalysts that when exposed to water and ultraviolet light, accelerate a chemical reaction. In laboratory experiments, Noceras solar cell prototype o

23、perated continuously for 45 hours without a drop in electrical output. Nocera notes that it works in any type of water. Nocera believes the artificial leaf could be especially useful as an inexpensive source of electricity for low-income populations in developing countries. The goal, Nocera says, is

24、 to make each home its own power station. He predicts a commercial version of the artificial leaf will be on the market within three years. 1 【正确答案】 B 【知识模块】 技术类 2 【正确答案】 A 【知识模块】 技术类 3 【听力原文】 Since the first artificial heart was implanted in a human here in Houston in 1969, the field has advanced s

25、teadily. But it hasn t kept pace with the need for devices that can keep patients alive until they can get a real organ transplant: Heart disease remains the number one killer of Americans each year. Of the estimated 5 million people in the United States with failing hearts, only around 2,000 are li

26、kely to get a transplant this year. That is where various types of artificial pumps have come into play. Last month, at the Texas Childrens Hospital here in Houston, Jordan Merecka, 17, became the first patient in a US pediatric hospital to have his congenitally deformed heart removed and replaced w

27、ith an external mechanical heart pump. Meeting with reporters a few days ago, he told how he almost ran out of time, waiting to have the procedure. Merecka, who now awaits a transplant, has limited mobility in the hospital as he remains tethered to the artificial heart beating loudly beside him. But

28、 nearby, at the Texas Heart Institute, doctors and researchers are working with another type of artificial heart, one that is much smaller, much more efficient and does not beat. The artificial heart Frazier and his colleague, Dr. William Conn, developed is small enough to be implanted in the human

29、chest. But, unlike an animal or human heart, it produces no pulse because it is a continuous-flow mechanism. It uses a small spinning turbine to keep blood flowing at a steady rate rather than a pump that mimics the action of the heart found in humans or in the calves the doctors have used for trial

30、s. To provide the blood flow of a natural human heart, vibrating pumps must beat 100,000 times a day, 35 million times a year, leading to mechanical breakdowns. The continuous-flow pumps are much more durable and can last years without a problem. 3 【正确答案】 D 【知识模块】 技术类 4 【正确答案】 D 【知识模块】 技术类 5 【听力原文】

31、Israels new anti-rocket system, called the Iron Dome, has passed final tests and will be deployed near the countrys borders by November. The system was produced by the state-owned Rafael Arms Development Authority and is partially financed by the United States. The Iron Dome will help neutralize the

32、 rocket threat from Hezbollah in Lebanon and Hamas in the Gaza Strip. The two Islamic militant groups have bombarded Israel with rockets in the past, exposing a strategic vulnerability. The system uses small radar-guided missiles to blow up incoming rockets with ranges of between five and 70 kilomet

33、ers. It can also destroy mortar shells in mid-air. The other benefit is deterrence. Defense officials warn that the system will not completely eliminate the rocket threat from Lebanon and Gaza. But they say it will sharply reduce the number of rockets able to hit populated areas and strategic facili

34、ties. One drawback is the cost. An interceptor missile costs $ 50,000, compared to just $ 500 for a Palestinian rocket. 5 【正确答案】 B 【 知识模块】 技术类 6 【正确答案】 A 【知识模块】 技术类 7 【听力原文】 Ever wonder why foods that are bad for you such as fat-laced potato chips and French fries taste so good? It turns out they fo

35、llow the same pleasure-inducing biochemical pathways through the body as marijuana does, encouraging people to keep eating even when they know they should stop. There used to be an old television commercial in the United States that boasted a certain brand of potato chip tasted so good, you could ne

36、ver eat just one. It turns out there is a biological reason for that. Daniele Piomelli is a professor of farm-ecology and biological chemistry at the University of California, Irvine. He says fat is an important component of healthy human cell membranes and high-fat foods, which are rare in the wild

37、, and were prized by early humans as a rich source of energy. As a result, Daniele Piomelli says humans developed a biological preference for fatty foods. Piomellis and colleagues have discovered a biological pathway that encouraged ancient humans to eat large quantities of the scarce nutrient whene

38、ver they found it for survival. Today, eating fat still provokes feelings of pleasure and satisfaction, similar to the high people get when smoking marijuana. Piomelli said when fatty foods are swallowed and hit the upper digestive tract, they trigger the production of endocannabinoids. Thats the sa

39、me class of feel-good chemicals that marijuana, or cannabis, stimulates in the brain. Endocannabinoids in the gut send a surge of cell-signaling to the brain, which shoots back a message telling the body to keep eating. Piomelli and colleagues discovered the fat pathway in research with rats. 7 【正确答

This true-color map of the full continent took eight years to compile from satellite pictures and is now free

41、ly available to the public over the Internet. Robert Bindschadler is a chief scientist at the US space agency NASAs Goddard Space Flight Center. Bindschadler told a news conference Tuesday that the new satellite images provide a time-lapse historical record of how Antarctica has changed. The map wil

42、l enable scientists to continue to watch changes unfold, such as the movement of glaciers. Bindschadler says researchers can use the map to better plan scientific expeditions, geologists can better trace rock formations and biologists can obtain snapshots of the levels of lakes in Antarctica s deser

43、t ecosystems. Collaborators on the mapping project include the US Geological Survey, the National Science Foundation and the British Antarctic Survey. British researchers say the new images will be key to understanding climate change because Antarctica has experienced a temperature rise of almost th

44、ree degrees in the last 50 years almost 10 times the global average. They add that more than 80 percent of glaciers on the continent are now in a state of retreat, ice shelves are breaking up, and snow is melting at a faster rate. The Landsat 7 satellite is expected to continue taking images of Anta

46、e number of people who go hungry by 2015. But at a recent gathering in Nigeria of journalists and scientists from more than a dozen African countries, participants lamented the lack of importance that technology and science have played in achieving these goals. Dr Umar Bindir, the director general o

47、f Nigeria s National Office for Technology Acquisition and Promotion, spoke about the role science should play in development at the First Regional Workshop of the Science Journalism Cooperation. Bindir stressed that of the eight MDGs that have been laid out, the most essential is to halve poverty.

48、But he added that a lack of available statistics makes it extremely difficult. In Nigeria, where the conference was held, more than $6 billion has been spent on MDGs in the past four years, but 70 percent of the population still lives in poverty. UNICEF adviser for water, hygiene and sanitation in W

49、est and Central Africa, Chris Cormency, said Senegal is one country that has used technology to make some of these improvements. 11 【正确答案】 D 【知识模块】 技术类 12 【正确答案】 D 【知识模块】 技术类 13 【听力原文】 Jeff Goodell thinks geoengineering is a somewhat crazy idea. But he writes in his book that after the failure of last year s Climate Change Conference in Copenhagen, the technological approach may end up being the worlds only option. He says there are two ways geoengineering might solve the global wanning problem: One would be to use tec
