1、2022 职称英语考试理工类 B 级阅读文章五Small But WiseOn December 14,NASA1 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 digital camera, and it will be taking pictures of some the wildest o

2、bjects2 in the known universe,including asteroids,faint stars,blazing galaxies3 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 haven t seen before,“said Ned Wright, a scientist who directs the WISE project.Sinc

3、e arriving in space,the WISE telescope has been circlingthe Earth,held by gravity in a polar orbit4(this means it crosses close to the north and south poles with each lap5).Its camera is pointed outward,away from the Earth,and WISE will snap a picture of a different part of the sky every 11 minutes.

4、 After six months it will have taken pictures across the entire sky.The pictures taken by WISE won t be like everyday digitalphotographs,however. WISE stands for“Wide-field Infrared Survey Explorer.“As its name suggests,the WISE camera takes pictures of features that give off infrared radiation6.Rad

5、iation is energy that travels as a wave. Visible light, including the familiar spectrum of light7 that becomes visible in a rainbow,is an example of radiation. When an ordinary digital camera takes a picture of a tree,for example,it receives the waves of visible light that are reflected off the tree

6、. When these waves enter the camera through the lens,they re 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 eye

7、,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 一 but they absorb most of the light

8、 that reachesthem. They dont reflect light,so theyre difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will beable to produce images of them. During its mission WISE will take pictures of hundreds of thousands of asteroids.Brown dwarfs8 are another kind of

9、 deep-space object that will show up in WISEs pictures. These objects are“failed“ stars 一 which means they are not massive enough to jump start9 the same kind of reactions that power stars such as the sun. Instead,brown dwarfs simply shrink and cool down. Theyre so dim that theyre almost impossible

10、to see with visible light, but in the infrared spectrum they glow.词汇：trashcan infrared asteroid dwarf n.解释：n.垃圾箱adj.红外线n.小行星矮星1.NASA ( 美 国 国 家 航 空 航 天 局 )是 缩 写 词 ， 全 称 是 NationalAeronautics and SpaceAdministration2. the wildest objects ：任何你能想象得到的天体。 wild 有“未被人驯养的“荒唐的“离奇的“意思。3. faint stars, blazing g

11、alaxie 指的是那些只能看到微弱的光 和因燃烧而无法观看到的天体。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展观测和应用的气象卫星、导航卫星、 地球资源卫星等都采纳这种轨道。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.她最终一圈超过了其他 参赛者。6. infrared radiation：红外线辐射7. spectrum of light：光

12、谱，即，光辐射的波长分布区域。8. Brown dwarfs：褐矮星。褐矮星特别暗淡，很难发觉它们，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 carri

13、ed a digital camera in space.2. Which is NOT the synonym for the word “snap“ in the third paragraph?A make.B shoot.C takeD photograph.3. 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

14、 the ordinary camera does not.D reflects light that human eyes can see.4. 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 is difficult to take asteroids

15、 pictures by ordinary cameras,D The WISE telescope can take pictures of asteroids5.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 power stars like the sun.D Brown dwarfs are impossible to see with the WISE telescope. 答案与题解：1. C 短文的第一和其次段供应了答案。 WISE 的特别之处就在于，虽 然体积小， 但它的数码相机能拍到任何天体， 所以能够帮忙天文学家观测 到宇宙空间中 ( in the known universe )的未知天文现象。其他选项都 不是短文表达的意思。2. A snap 是个多义词， 可以解释为“拍照“，更为准确的意思是“拍 快照“。这里 shoot, take 和 photograph 都是 snap 的同义词。3. C 短文第六
