But appearances can be deceiving: Miles within its cracked, frigid shell, Europa probably hides giant pools o

8、f 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 have to investigate the moons surface for clues to what lies beneath. In a new study, scientists investigated one group of strange ice patterns

9、 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 slightly smaller than Earths moon, clearly show a tangled, icy mishmash of lines and cracks known as “chaos terrains. “ These chaotic place

10、s cover more than half of Europa. For more than 10 years, scientists have wondered what causes the formations. The new study suggests that they arise 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 hidi

11、ng 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 planetary 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

12、 now. “ Schmidt, a scientist at the University of Texas at Austin, and her colleagues wanted to know how chaos terrains form. Since they couldnt rocket to Europa to see for themselves, they searched for similar formations here on Earth. They studied collapsed ice shelves in Antarctica and icy caps o

13、n volcanoes in Iceland. Those features on Earth formed when liquid water mixed with ice. The scientists now suspect something similar might be happening on Europa: that as water and ice of different temperatures mingle and shift, the surface fractures. This would explain the jumbled ice sculptures.

14、“Fracturing catastrophically disrupts the ice in the same way that it causes ice shelves to collapse on Earth,“ Schmidt told Science News. She 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 oxy

15、gen 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 underground pool of Europa is estimated equivalent with that of the US Great lakes. （ A） Right （ B） Wrong （ C） Not mention 17 The strange ice patterns on Eur

16、opa are formed as a result of a giant underground water pool. （ A） Right （ B） Wrong （ C） Not mention 18 Europa is the most recently discovered one among Jupiters moons. （ A） Right （ B） Wrong （ C） Not mention 19 The size of Europa is a bit larger than that of Earths moon. （ A） Right （ B） Wrong （ C） N

17、ot mention 20 Schmidt and her colleagues are the first group of scientists discovering Europa. （ A） Right （ B） Wrong （ C） Not mention 21 The formations on Europas surface are rather unique. （ A） Right （ B） Wrong （ C） Not mention 22 The existence of liquid water is a necessity for a life-support. （ A

18、） Right （ B） Wrong （ C） Not mention 三、 概括大意与完成句子 (第 23-30题，每题 1分，共 8分 ) 下面的短文后有 2项测试任务： (1)第 23-26题要求从所给 的 6个选项中为第 2-5段每段选择一个最佳标题； (2)第 27-30题要求从所给的 6个选项中为每个句子确定一个最佳选项。 22 Learn about Noble Gases(惰性气体 ) Have you ever ridden on a balloon? Many tourist spots offer balloon rides in order for people to

19、see the beauty of a place from above. A balloon contains a noble gas called helium(氦 ). Formerly, balloons contained hydrogen but hydrogen is very flammable and dangerous when uncontrolled. Therefore, people shifted to helium, which is safer. Helium is safe because it has the properties of the noble

20、 gases. People once believed that noble gases couldnt chemically react at all. For this reason, they were called inert gases(惰性气体 ). They were also listed under Group 0 in the old periodic table because scientists believed that the gases have zero valence(价 )electrons in their outer shell. This was

21、later proven to be untrue when some noble gas compounds were discovered. The gases are elements, which share similar properties. These properties include being monoatomic, colorless, odorless, being able to conduct electricity, and having low chemical reactivity. Noble gases include Helium, Neon, Ar

22、gon, Krypton, Xenon and Radoa 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 charge. Helium has the lowest molecular(分子的 )weight while Radon is the heaviest.

23、 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 is more reactive. Noble gases have a full outer shell, meaning that they have c

24、omplete 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 noble gases because of the low chemical reactivity of these said gases. Because of

25、their properties, noble gases have many important applications. They are widely used in medicine and industries. For instance, liquid Helium is used for superconducting magnets(磁体 ). These magnets are very important in physics and medicine. When a doctor suspects that a persons brain has been damage

26、d, he might request for Magnetic Resonance Imaging(MRI). MRI allows the doctor to “see“ the brain, without operating on the patient. A. what is the periodic table? B. What are noble gases? C. What causes the low chemical reactivity of noble gases? D. How were noble gases discovered? E. How were nobl

27、e gases understood in the past? F. what are the applications of noble gases? 23 paragraph 2_. 24 paragraph 3_. 25 paragraph 4_. 26 paragraph 5_. 26 A. reactive B. lightest C. important D. complete E. flammable F. unnecessary 27 Noble gases are not very chemically_. 28 Among the elements of noble gas

28、es Helium is the_. 29 The required number of electrons in noble gases outer shell is_. 30 MRI may make operating on the patient_. 四、 阅读理解 (第 31-45题，每题 3分，共 45分 ) 下面有 3篇短文后有 5道题。请根据短文内容，为每题选 1个最佳选项。 30 Gross National Happiness In the last century, new technology improved the lives of many people in m

29、any countries. However, one country resisted these changes. High in the Himalayan mountains of Asia, the kingdom of Bhutan remained separate. Its people and Buddhist(佛教 )culture had not been affected for almost a thousand years. Bhutan, however, was a poor country. People died at a young age. Most o

30、f its people could not read, and they did not know much about the outside world. Then, in 1972, a new ruler named King Jigme Singye Wang-chuck decided to help Bhutan to become modern, but without losing its traditions. King Wangchuck looked at other countries for ideas. He saw that most countries me

31、asured their progress by their Gross National Product(GNP). The GNP measures products and money. When the number of products sold increases, people say the country is making progress. King Wangchuck had a different idea for Bhutan. He wanted to measure his countrys progress by peoples happiness. If

32、the peoples happiness increased, the king could say that Bhutan was making progress. To decide if people were happier, he created a measure called Gross National Happiness(GNH). GNH is based on certain principles that create happiness. People are happier if they have health care, education, and jobs

33、. They are happier when they live in a healthy, protected environment. They are happier when they can keep their traditional culture and customs. Finally, people are happier when they have a good, stable government. Now there is some evidence of increased GNH in Bhutan. People are healthier and are

34、living longer. More people are educated and employed. Twenty-five percent of the land has become national parks, and the country has almost no pollution. The Bhutanese continue to wear their traditional clothing and follow their ancient Buddhist customs. Bhutan has also become a democracy. In 2008,

35、King Wangchuck gave his power to his son. Although the country still had a king, it held its first democratic elections that year. Bhutan had political parties and political candidates for the first time. Finally, Bhutan has connected to the rest of the world through television and internet. Bhutan

36、is a symbol for social progress. Many countries are now interested in Bhutans GNH. These countries are investigating their own ways to measure happiness. They want to create new policies that take care of their people, cultures, and land. Brazil may be the next country to use the principles of GNH.

37、Brazilian leaders see the principles of GNH as a source of inspiration. Brazil is a large country with a diverse population. If happiness works as a measure of progress in Brazil, perhaps the rest of the world will follow. 31 Who was Jigme Singye Wangchuck? （ A） A president. （ B） A Buddhist priest.

38、（ C） A king. （ D） A general. 32 Apart from modernizing Bhutan, what else did Wangchuck want to do for Bhutan? （ A） To make its population grow. （ B） To keep it separate from the world. （ C） To keep its traditions and customs. （ D） To encourage its people to get rich. 33 A country shows its progress

39、with GNP by_. （ A） selling more products （ B） spending more money （ C） spending less money （ D） providing more jobs 34 According to GNH, people are happier if they_. （ A） have new technology （ B） have a good, stable government （ C） can change their religion （ D） have more money 35 Today many countri

40、es are_. （ A） using the principles of GNH to measure their progress （ B） working together to develop a common scale to measure GNH （ C） taking both Bhutan and Brazil as symbols for social progress （ D） trying to find their own ways to measure happiness 35 Download Knowledge Directly to Your Brain Fo

41、r the first time, researchers have been able to hack into 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 co

42、uld lead to new teaching and rehabilitation techniques. Future 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

43、 Neuroscience Laboratories in Kyoto used functional magnetic 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 adul

44、ts can do this as well as young people has been an ongoing 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 fMR

45、I to watch the participants brain activity. The researchers 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

46、 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 ac

47、tivation patterns in their visual cortices. “Participants can be trained to control the overall mean activation of an entire brain region,“ the study authors write, “or the activation in one region relative to that in another region. “ This worked even when test subjects were not aware of what they

48、were learning, the researchers said. “The most surprising thing in this study is that mere inductions of neural activation patterns corresponding to a specific visual feature led to visual performance improvement on the visual feature, without presenting the feature or subjects awareness of what was

49、 to be learned,“ Watanabe said in a statement. Watanabe and colleagues said this method can be a powerful tool. “It can incept a person to acquire new learning, skills, or memory, or possibly to restore skills or knowledge that has been damaged through accident, disease, or aging, without a persons awareness of what is learned or memorized,“ they write. 36 What have researchers been able to do with the help of the study? （ A） Discover a persons learning pr
