7、提及，请选择C。 Image Martian Dust Particles NASAs Phoenix Mars Lander has taken its first-ever picture of a single particle of rusty Martian dust with one of its microscopes. The dust particles of dust was shown at a higher magnification than anything outside of the Earth that has been imaged before. The

8、rounded particle measured only about one micrometer, or one millionth of a meter, across. Taking this image required the highest resolution microscope operated off Earth and a specially designed device to hold the Martian dust,” said Tom Pike, a phoenix science team member from Imperial College Lond

9、on. “ We always knew it was going to be technically very challenging to image particles this small.” The device that imaged the dust speck is called an atomic force microscope, which maps the shape of particles in three dimensions by scanning them with a sharp tip at the end of a spring. The atomic

10、force microscope can detail the shape of particles as small as about 100 nanometers. And this wont be the last dust particle that Phoenix will image. “After this first success, were now working on building up a portrait gallery of the dust on Mars.” Pike said. Dust exists everywhere on Mars, coating

31、n a means of communicationhaving a mobile phone shows that they are cool and connected.The explosions around the world in mobile phone use make some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In En

32、gland, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.On the other hand, why do some medical studies show changes in the brain cells of some pe

33、ople who use mobile phone? Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a traveling salesman had to retire at a young age because of serious memory loss. He couldnt remember even simple tasks. He would often forget the name of his

34、own son. This man used to talk on his mobile phone for about six hours a day, every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employers doctor didnt agree.What is it that makes mobile phones potentially harmful? The answer is radiation. Hi

35、gh-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say tha amount is too small to worry about.As the discussion about their safety continues, it appears that its best to use mobile phones less often. Use

36、 your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phone may have a warning label that says they are bad for your health. So for now, its wise n

37、ot to use your mobile phone too often.31. People buy cell phones for the following reasons EXCEPT that. A. theyre popular.B. theyre cheap.C. theyre useful.D. theyre convenient.32.

40、hones C. to use mobile phones less often D. to stop using mobile phones 第二篇A Small but Mighty TelescopeOn December14，NASA blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Dont let its small size fool you: WISE has a powerful dig

41、ital camera, and it will be taking pictures of some of the wildest objects in the unknown universe, including asteroids, faint stars, blazing galaxies and giant clouds of dust where planets and stars are born. “Im very excited because were going to be seeing parts of the universe that we havent seen

42、 before,” said Ned Wright, a scientist who directs the WISE project. Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit. Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the sky every 11 min

43、utes. After six months it will have taken pictures across the entire sky. The pictures taken by WISE wont be like everyday digital photographs, however. WISE stands for “Wide-field Infrared Survey Explorer.” As its name suggests, the WISE camera takes pictures of features that give off infrared radi

44、ation. Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light that becomes visible in a rainbow, is an example of radiation. When an ordinary digital camera takes a picture of a tree, it receives the waves of visible light that are reflected off the tree.

45、 When these waves enter the camera through the lens, they are processed by the camera, which then puts the image together. Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras dont see them, and neither do the eyes of human beings. Although invisible to the

46、 eye, longer infrared radiation can be detected as warmth by the skin. Thats a key idea to why WISE will be able to see things other telescopes cant. Not everything in the universe shows up in visible light. Asteroids, for example, are giant rocks that float through space but they absorb most of the

47、 light that reaches them. They dont reflect light, so theyre difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids. Brown dwarfs are anothe

48、r kind of deep-space object that will show up in WISEs pictures. These objects are “failed” stars which means that they are not massive enough to jump start the same kind of reactions that power stars such as the sun. Instead, brown dwarfs simply shrink and cool down. They are so dim that they are a

49、lmost impossible to see with visible light, but in the infrared spectrum they glow. 36. What is so special about WISE? _A. It is small in size but carries a large camera. B. It is as small as a trashcan. C. Its digital camera can help astronomers to see the unknown space. D. never before has a teles

50、cope carried a digital camera in space. 37. Which is NOT the synonym for the word “snap” in the third paragraph? A. make B. shoot C. take D. photograph 38. The camera on WISE _. A. is no different from an ordinary cameraB. does not see infrared radiation while the ordinary camera does C. catches the

51、 infrared radiation while the ordinary camera does not. D. reflects light that human eyes can see 39. Which of the following is NOT correct about “asteroids” according to paragraph 7? A. Asteroids float through space giving off visible light. B. Asteroids do not reflect light that reaches them.C. It

52、 is difficult to take asteroids pictures by ordinary cameras. D. The WISE telescope can take pictures of asteroids.40. What is implied in the last paragraph? A. Brown dwarfs give off visible light. B. Brown dwarfs give off infrared radiation. C. Brown dwarfs are powerful stars like the sun.D. Brown

53、dwarfs are impossible to see with the WISE telescope.第三篇 Renewable Energy Sources Today petroleum（石油）provides around 40% of the worlds energy needs, mostly fuelling automobiles. Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it is the least efficient, unh

54、ealthiest and most environmentally damaging fossil fuel（矿物燃料）.Natural gas reserves could fill some of the gap from oil, but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. Less-polluting renewable energy so

55、urces offer a more practical long-term energy solution. Renewable refers to the fact that these resources are not used faster than they can be replaced. Hydroelectric（水力发电旳）power is now the most common form of renewable energy, supplying around 20% of world electricity. Chinas Three Gorges Dam is th

56、e largest ever. At five times the size of the USs Hoover Dam, its 26 turbines（涡轮机）will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of Chinas entire electricity demand. In ,the first commercial power station to use tidal（潮汐旳）currents in the open sea opened in No

57、rway. It is designed like windmill（风）,but others take the form of turbines. As prices fall, wind power has become the fastest growing type of electricity generation-quadrupling（翻两番）worldwide between 1999 and .Modern wind farms consist of turbines that generate electricity. Though it will be more exp

58、ensive, there is more than enough wind to provide the worlds entire energy needs. Wind farms come in onshore and offshore forms. They can often end up at spots of natural beauty, and are often unpopular with residents. And turbines are not totally harmless-they can interfere with radar, alter climat

59、e and kill sea birds. Scotland is building Europes largest wind farm, which will power 200,000 homes. The UKs goal is to generate one-fifth of power from renewable sources, mainly wind, by .But this may cause problems, because wind is unreliable. 41.According to the passage, which of the following i

60、s the most polluting energy resource? A. Petroleum. B. Coal. C. Natural gas D. Water. 42.Chinas Three Gorges Dam A. is the first hydroelectric dam in the world. B. is of the same size as the USs Hoover Dam. C. can generate around 3% of world electricity. D. is the largest hydroelectric dam in the wo
