1、2012年职称英语理工类新增A级文章篇目阅读理解（2篇） +四五篇Teaching Math, Teaching Anxiety+四十六篇Ants Have Big Impact on Environment as Ecosystem Engineers完形填空（2篇） +十三篇 Solar Power without Solar Cells+第十五篇 “Liquefaction” Key to Much of Japanese Earthquake Damage注：1、+表示A级文章；*表示B即文章；其他为C级文章；2、完形填空请参见第#页；第四五篇Small But Wise小而聪明On
2、December 14,NASA1 blasted a small but mighty telescope into space. The telescope is12月14日，美国国家航空航天局发射了一个体积小而威力大的望远镜，它的名字叫“WISE”(聪明)called WISE and is about as wide around as a trashcan. Dont let its small size fool you:WISE has大约只有一个垃圾盒子那么宽。你可千万不要轻视这个小东西，WISE可是一款高强数码相机a powerful digital camera, and
3、it will be taking pictures of some the wildest objects2 in the known它将在人类已知的宇宙里拍摄任何你所universe,including asteroids,faint stars,blazing galaxies3 and giant clouds of dust where planets能想到的天体，包括小行星、那些只能看到微弱的光和因燃烧而无法观察到的天and stars are born.体，以及自行星和恒星诞生以来的巨大尘埃云Im very excited because were going to be see
4、ing parts of the universe that we havent seenNed Wright是主持WISE项目的科学家他说：“我十分兴奋，因为我们就before,said Ned Wright, a scientist who directs the WISE project.要看到以前从未看到过的那部分宇宙”。Since arriving in space,the WISE telescope has been circling the Earth,held by gravity in a到达宇宙空间后，WISE由于受极地轨道重力作用，一直在围绕地球旋转。polar orb
5、it4(this means it crosses close to the north and south poles with each lap5).Its camera is(这意味着，每转一圈，它就离南极和北极靠近)。它的镜头是向外的，远离地球。pointed outward,away from the Earth,and WISE will snap a picture of a different part of the sky每11分钟WISE就会抓拍天空一个不同的部分。六个月之后，它将把整个天空every 11 minutes. After six months it will
6、 have taken pictures across the entire sky.拍摄完毕。 The pictures taken by WISE wont be like everyday digital photographs,however. WISE然而，WISE拍摄的相片不会像我们日常的数码相片。WISE是Wide-fieldstands forWide-field Infrared Survey Explorer.As its name suggests,the WISE camera takesInfrared Survey Explorer(广域红外戡测探测器)的缩写。正如
7、名字所示，WISE能pictures of features that give off infrared radiation6.Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of辐射是波浪状行进的一种能量。人能看到的光，包括大家熟悉的、在彩虹里light7 that becomes visible in a rainbow,is an example of radiation. When an ordinary digital看到的光谱就是射线的一个例子。当
8、普通的数码相机给一棵树照相时，它能接收camera takes a picture of a tree,for example,it receives the waves of visible light that are reflected off 到树反射回来的、可见的光波。the tree. When these waves enter the camera through the lens,theyre processed by the camera,which 光波通过镜头进入到相机里，相机对它进行加工，then puts the image together.然后把图像合成Wave
9、s of infrared radiation are longer than waves of visible light, so ordinary digital cameras红外线的波长比可见光长，所以，普通的数码相机捕捉不到他们，人眼也看dont see them,and neither do the eyes of human beings. Although invisible to the eye,longer不到这种射线。infrared radiation can be detected as warmth by the skin.尽管人们看不到，人的皮肤能感受到较长红外线
10、带来的温暖。Thats a key idea to why WISE will be able to see things other telescopes cant. Not这就是为什么WISE能捕捉到其他望远镜看不到的物体的主要原因。宇宙everything in the universe shows up in visible light. Asteroids,for example,are giant rocks that中，不是所有的东西都以可见光的方式呈现出来。例如，小行星是在太空中漂浮float through space 一but they absorb most of the
11、 light that reaches them. They dont reflect light,so 的大岩石，但是小行星吸收射到他们表面的大部分光。他们不能反射光，所以要theyre difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will 看到他们很困难。但他们却释放出红外线，所以，象WISE这样的红外线望远镜be able to produce images of them. During its mission WISE will take p
12、ictures of才能够捕捉到它们的图像。hundreds of thousands of asteroids.WISE的任务就是拍摄成千上万的小行星图像。Brown dwarfs8 are another kind of deep-space object that will show up in WISEs pictures.WISE的另一任务是为另外一种太空深处的天体一褐矮星拍照。这种天体是These objects arefailed stars 一which means they are not massive enough to jump start9 the“失败的”恒星，它们
13、是一些不够大，不能像太阳的能量那样启动相同的反应。褐same kind of reactions that power stars such as the sun. Instead,brown dwarfs simply shrink and矮星只能缩小和冷却。cool down. Theyre so dim that theyre almost impossible to see with visible light, but in the他们发出的光如此之微弱，人们根本看不到，但是在红外infrared spe ctrum they glow.频谱中，它们是发光的。词汇：trashcan
14、/ tr,kn/n垃圾箱infrared/infrred/ adj红外线asteroid/strid/ n.小行星dwarf/dw:f/ n. 矮星注释：1.NASA （美国国家航空航天局）是缩写词，全称是National Aeronautics 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 galaxies：指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
15、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。8. 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? 什么是特别的聪明？A It is small in size but carries a large camera. 它是规模小，但携带大型照相机。B It is as small as a trashcan. 它是作为一个小垃圾桶。C Its digital camera can help astronomers to see the unkno
