8、 bright and icy on the surface. But appearances can be deceiving: Miles within its cracked, frigid shell, Europa probably hides giant pools of liquid water. Where scientists find liquid water, they hope to find life as well.Since we cant go diving into Europas depths just yet, scientists instead hav

9、e to investigate the moons surface for clues to what lies beneath. In a new study, scientists investigated one group of strange ice patterns on Europa and concluded that the formations mark the top of an underground pool that holds as much water as the U.S. Great Lakes.Pictures of Europa, which is s

10、lightly smaller than Earths moon, clearly show a tangled(错综复杂旳), icy mishmash（混合物） of lines and cracks known as “chaos terrains.（混乱地形）” These chaotic places cover more than half of Europa. For more than 10 years, scientists have wondered what causes the formations. The new study suggests that they a

11、rise from the mixing of vast underground stores of liquid water with icy material near the surface.For scientists who suspect that Europa also may be hiding life beneath its icy surface, the news about the new lake is exciting.“It would be great if these lakes harbored life,” Britney Schmidt, a plan

12、etary scientist who worked on the study, told Science News. “But even if they didnt, they say that Europa is doing something interesting and active right now.”Schmidt, a scientist at the University of Texas at Austin, and her colleagues wanted to know how chaos terrains form. Since they couldnt rock

13、et to Europa to see for themselves, they searched for similar formations here on Earth. They studied collapsed ice shelves in Antarctica and icy caps on volcanoes in Iceland. Those features on Earth formed when liquid water mixed with ice. The scientists now suspect something similar might be happen

14、ing on Europa: that as water and ice of different temperatures mingle and shift, the surface fractures. This would explain the jumbled（混乱旳）ice sculptures.“Fracturing catastrophically（劫难性旳）disrupts the ice in the same way that it causes ice shelves to collapse on Earth,” Schmidt told Science News. Sh

15、e and her team found that the process could be causing chaos terrains to form quickly on Europa.The new study suggests that on this moon, elements such as oxygen from the surface blend with the deep bodies of water. That mixture may create an environment that supports life.16. The liquid water of an

19、idden on a balloon? Many tourist spots offer balloon rides in order for people to see the beauty of a place from above. A balloon contains a noble gas called helium. Formerly, balloons contained hydrogen but hydrogen is very flammable and dangerous when uncontrolled. Therefore, people shifted to hel

20、ium, which is safer. Helium is safe because it has the properties of the noble gases.2. People once believed that noble gases couldnt chemically react at all. For this reason, they were called inert gases. They were also clustered under Group 0 in the old periodic table because scientists believed t

21、hat the gases have zero valence electrons in their outer shell. This was later proven to be untrue when some noble gas compounds were discovered.3. The gases are elements, which share similar properties. These properties include being monoatomic, colorless, odorless, being able to conduct electricit

22、y, and having low chemical reactivity. Noble gases include Helium, Neon, Argon, Krypton, Xenon and Radon. These are all found in Group 18, in the rightmost column of the periodic table. If you look at the periodic table, you will notice that these elements are the only ones, which do not have a char

23、ge. Helium has the lowest molecular（分子旳） weight while Radon is the heaviest.4. Remember that chemical reactions occur because atoms have “valence” electrons, which are electrons in their outer shell. When the outer shell is “unfilled” or the required number of electrons is not yet complete, the atom

24、 is more reactive. Noble gases have a full outer shell, meaning that they have complete electrons in their outer shell. This complete number varies. For instance, the outer shell of Helium has 2 valence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few nob

25、le gases because of the inherent low chemical reactivity of these said gases.5. Because of their properties, noble gases have many important applications. They are widely used in recreation, medicine and industries. For instance, Liquid Helium is used for superconducting magnets（磁体）. These magnets a

26、re very important in physics and medicine. When a doctor suspects that a persons brain has been damaged, he might request for Magnetic Resonance Imaging (MRI). MRI allows the doctor to “see” the brain, without operating on the patient.23. Paragraph 2 24. Paragraph 325. Paragraph 426. Paragraph 5【答案】

30、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 before，” said Ned Wright，a scientist who directs the WISE projectSince arriving in space，the W

31、ISE telescope has been circling the Earth，held by gravity in a polar orbit(this means it crosses close to the north and south poles with each lap)Its camera is pointed outward，away from the Earth，and WISE will snap a picture of a different part of the sky every 11 minutesAfter six months it will hav

32、e taken pictures across the entire skyThe pictures taken by WISE wont be like everyday digital photographs，howeverWISE stands for “Wide-field Infrared Survey Explorer” As its name suggests，the WISE camera takes pictures of features that give off infrared radiationRadiation is energy that travels as

33、a waveVisible light，including the familiar spectrum of light that becomes visible in a rainbow，is an example of radiationWhen an ordinary digital camera takes a picture of a tree，for example，it receives the waves of visible light that are reflected off the treeWhen these waves enter the camera throu

34、gh the lens，theyre processed by the camera，which then puts the image togetherWaves of infrared radiation are longer than waves of visible light，so ordinary digital cameras dont see them，and neither do the eyes of human beingsAlthough invisible to the eye，longer infrared radiation can be detected as

35、warmth by the skinThats a key idea to why WISE will be able to see things other telescopes cant. Not everything in the universe shows up in visible lightAsteroids，for example，are giant rocks that float through spacebut they absorb most of the light that reaches themThey dont reflect light，so theyre

36、difficult to seeBut they do give off infrared radiation，so an infrared telescope like WISE will be able to produce images of themDuring its mission WISE will take pictures of hundreds of thousands of asteroidsBrown dwarfs are another kind of deep-space object that will show up in WISEs picturesThese

37、 objects are “failed” stars-which means they are not massive enough to jump start the same kind of reactions that power stars such as the sunInstead，brown dwarfs simply shrink and cool downTheyre so dim that theyre almost impossible to see with visible light，but in the infrared spectrum they glow31.

38、 What is so special about WISE?A. It is as small as a trashcanC. Never before has a telescope carried a digital camera in spaceB. It is small in size but carries a large cameraD. Its digital camera can help astronomers to see the unknown space32. The camera on WISE A. produces images of objects givi

39、ng off infrared radiation.B. is equipped with expensive computersC. reflects light visible to the human eyeD. is similar to an ordinary digital camera33. It is true that infrared radiationA. is not detectable to humanB. looks bright than visible lightC. is visible light reflected off an objectD. has

40、 longer waves that those of visible light 34. Which of the following statements about asteroid is NOT true?A. The WISE telescope can take pictures of asteroids.B. They do not reflect light that reaches themC. They are invisible to ordinary cameraD. They float through space giving off visible light35

41、. It can be inferred from the last paragraph that brown dwarfs?A. are power stars like the sun.B. give off visible lightC. become massive and activeD. are invisible to the WISE telescope【答案】：DADDB第二篇Download Knowledge Directly to Your Brain For the first time, researchers have been able to hack into

42、 the process of learning in the brain, using induced brain patterns to create a learned behavior. Its not quite as advanced as an instant kung-fu download, and its not as sleek as cognitive inception, but its still an important finding that could lead to new teaching and rehabilitation techniques. F

43、uture therapies could decode the brain activity patterns of an athlete or a musician, and use them as a benchmark for teaching another person a new activity, according to the researchers. Scientists from Boston University and ATR Computational Neuroscience Laboratories in Kyoto used functional magne

44、tic resonance imaging, or fMRI, to study the learning process. They were examining the adult brains aptitude for visual perceptual learning, or VPL, in which repetitive training improves a persons performance on a particular task. Whether adults can do this as well as young people has been an ongoin

45、g debate in neuroscience. Led by BU neuroscientist Takeo Watanabe, researchers used a method called decoded fMRI neurofeedback to stimulate the visual cortex. First they showed participants circles at different orientations. Then they used fMRI to watch the participants brain activity. The researche

46、rs were then able to train the participants to recreate this visual cortex activity. The volunteers were again placed in MRI machines and asked to visualize shapes of certain colors. The participants were asked to “somehow regulate activity in the posterior part of the brain” to make a solid green disc as large as they could. They were told they would get a paid bonus proportional to the size of this disc, but they werent told anything about what the disc meant. The researchers watched the participants brain activity and monitored the activation patterns in their visual cortices. “Parti
