1、职称英语理工A新增文章整理含答案及翻译阅读理解+第四五篇 Small But WiseOn December 14,NASA1 blasted a small but mighty telescope into space. The telescope iscalled WISE and is about as wide around as a trashcan. Dont let its small size fool you:WISE hasa powerful digital camera, and it will be taking pictures of some the wilde

2、st objects2 in the knownuniverse,including asteroids,faint stars,blazing galaxies3 and giant clouds of dust where planetsand stars are born.Im very excited because were going to be seeing parts of the universe that we havent seenbefore,said Ned Wright, a scientist who directs the WISE project.Since

3、arriving in space,the WISE telescope has been circling the Earth,held by gravity in apolar orbit4(this means it crosses close to the north and south poles with each lap5).Its camera ispointed outward,away from the Earth,and WISE will snap a picture of a different part of the skyevery 11 minutes. Aft

4、er six months it will have taken pictures across the entire sky.The pictures taken by WISE wont be like everyday digital photographs,however. WISEstands forWide-field Infrared Survey Explorer.As its name suggests,the WISE camera takespictures of features that give off infrared radiation6.Radiation i

5、s energy that travels as a wave. Visible light, including the familiar spectrum oflight7 that becomes visible in a rainbow,is an example of radiation. When an ordinary digitalcamera takes a picture of a tree,for example,it receives the waves of visible light that are reflected off the tree. When the

6、se waves enter the camera through the lens,theyre processed by the camera,which then puts the image together.Waves of infrared radiation are longer than waves of visible light, so ordinary digital camerasdont see them,and neither do the eyes of human beings. Although invisible to the eye,longerinfra

7、red 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. Noteverything in the universe shows up in visible light. Asteroids,for example,are giant rocks thatfloat through space 一but they absorb most of the light that reaches th

8、em. 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 ofhundreds of thousands of asteroids.Brown dwarfs8 are another kind of deep-space obj

9、ect that will show up in WISEs pictures.These objects arefailed stars 一which means they are not massive enough to jump start9 thesame kind of reactions that power stars such as the sun. Instead,brown dwarfs simply shrink andcool down. Theyre so dim that theyre almost impossible to see with visible l

11、的是那些只能看到微弱的光和因燃烧而无法观察到的天体。4. polar orbit:极地轨道。指轨道平面与赤道面夹角为90。的人造地球卫星轨道。人造卫星运行时能到达南北极区上空,即卫星能飞经全球范围的上空。需要在全球范围内进行观测和应用的气象卫星、导航卫星、地球资源卫星等都采用这种轨道。5. lap:一圈。原指竞赛场的一圈或游泳池的一个来回,如: She overtook the other runners on the last lap. 她最后一圈超过了其他参赛者。6. infrared radiation:红外线辐射7. spectrum of light:光谱,即,光辐射的波长分布区域。

Brown dwarfs:褐矮星。褐矮星非常暗淡,很难发现它们,要确定它们的大小就更加困难。9.jump start: 启动练习:1 .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 telescope carried a digital cam

The camera on WISEA is no different from an ordinary camera.B does not see infrared radiation while the ordinary camera does.C catches the infrared radiation while the ordinary came

Which of the following is NOT correct aboutasteroids according to paragraph 7?A Asteroids float through space giving off visible light.B Asteroids do not reflect light that reaches them.C It is difficult to take asteroids pictures by ordinary c

16、Big Impact on Environment as Ecosystem EngineersResearch by the University of Exeter1 has revealed that ants have a big impact on their local environment as a result of their activity as ecosystem engineers and predators. The study, published in the Journal of Animal Ecology, found that ants have tw

17、o distinct effects on their local environment.Firstly, through moving of soil by nest building2 activity and by collecting food they affect the level of nutrients in the soil. This can indirectly impact the local populations of many animal groups, from decomposers to species much higher up the food

18、chain.Secondly, they prey on a wide range of other animals, including larger prey which can be attacked by vast numbers of ant workers.Dirk Sanders, an author of the study from the universitys Centre for Ecology and Conservation, said:Ants are very effective predators which thrive in huge numbers. T

19、heyre also very territorial3 and very aggressive, defending their resources and territory against other predators. All of this means they have a strong influence on their surrounding area.In this research, we studied for the first time how big this impact is and the subtleties of it. What we found i

20、s that despite being predators, their presence can also lead to an increase in density and diversity of other animal groups4. They genuinely play a key role in the local environment, having a big influence on the grassland food web, Sanders said.The study, carried out in Germany, studied the impact

21、of the presence of different combinations and densities of black garden ants and common red ants, both species which can be found across Europe, including in the UK. It found that a low density of ants in an area increased the diversity and density of other animals in the local area, particularly th

22、e density of herbivores and decomposers. At higher densities ants had no or the opposite effect, showing that predation is counteracting the positive influence.Dr Frank van Veen, another author on the study, said:What we find is that the impact of ants on soil nutrient levels has a positive effect o

23、n animal groups at low levels, but as the number of ants increases, their predatory impacts have the bigger effect thereby counteracting the positive influence via ecosystem engineering.Ants are important components of ecosystems not only because they constitute a great part of the animal biomass5 b

24、ut also because they act as ecosystem engineers. Ant biodiversity6 is incredibly high and these organisms are highly responsive to human impact, which obviously reduces its richness. However, it is not clear how such disturbance damages the maintenance of ant services to the ecosystem Ants are impor

As predators, antsA prey on small as well as large animals.B collect nutritious food from the soilC collect food as decomposers.D prey on species much higher up the food chain.3.
