Small But Wise m very excited because were going to be seeing parts of the universe that we havent seen before,said Ned Wright, a scientist who directs the WISE project. The pictures taken by WISE wont be like everyday digital photographs,however. WISE stands forWide-field Infrared Survey Explorer.As its name suggests,the WISE camera takes pictures of features that give off infrared radiation6. 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,longer infrared radiation can be detected as warmth by the skin. Brown dwarfs8 are another kind of deep-space object that will show up in WISEs pictures. These objects arefailed 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 to see with visible light, but in the infrared spectrum they glow. trashcan n.垃圾箱 asteroid n.小行星 注釋?zhuān)?Administration 3. faint stars, blazing galaxies：指的是那些只能看到微弱的光和因燃燒而無(wú)法觀(guān)察到的天體。 5. lap：一圈。原指競賽場(chǎng)的一圈或游泳池的.一個(gè)來(lái)回，如： She overtook the other runners on the last lap. 她最后一圈超過(guò)了其他參賽者。 7. spectrum of light：光譜，即，光輻射的波長(cháng)分布區域。 9.jump start: 啟動(dòng) 1 .What is so special about WISE? B It is as small as a trashcan. D Never before has a telescope carried a digital camera in space. A make. C take 3. The camera on WISE B does not see infrared radiation while the ordinary camera does. D reflects light that human eyes can see. A Asteroids float through space giving off visible light. C It is difficult to take asteroids pictures by ordinary cameras, 5.What is implied in the last paragraph? B Brown dwarfs give off infrared radiation. D Brown dwarfs are impossible to see with the WISE telescope. 1. C 短文的第一和第二段提供了答案。WISE 的特殊之處就在于，雖然體積小，但它的數碼相機能拍到任何天體，所以能夠幫助天文學(xué)家觀(guān)測到宇宙空間中的未知天文現象。其他選項都不是短文表達的意思。 3. C 短文第六段和第四段提供了答案。人類(lèi)的肉眼和普通相機看到的光是visible lights ，看不見(jiàn)紅外線(xiàn)輻射 ，而WISE 的相機能夠看到。 5. B 最后一段的第一句說(shuō)，褐矮星能出現在WISE 照片中，根據上文對WISE 望遠鏡的描述只有WISE 望遠鏡才能拍到紅外線(xiàn)射線(xiàn)，所以B是正確選擇。
