But appearances can be deceiving: Mileswithin its cracked, frigid shell, Europa probably hides giant pools of

7、liquidwater. Where scientists find liquid water, they hope to find life as well.Since we cant go diving into Europasdepths just yet, scientists instead have to 教育联展网 中国最实效的教育培训门户网站 www.theA.cn3investigate the moons surface forclues to what lies beneath. In a new study, scientists investigated one gr

8、oupof strange ice patterns on Europa and concluded that the formations mark thetop of an underground pool that holds as much water as the U.S. Great Lakes.Pictures of Europa, which is slightlysmaller than Earths moon, clearly show a tangled, icy mishmash of lines andcracks known as “chaos terrains.”

9、 These chaotic places cover more than half ofEuropa. For more than 10 years, scientists have wondered what causes theformations. The new study suggests that they arise from the mixing of vastunderground stores of liquid water with icy material near the surface.For scientists who suspect that Europaa

10、lso may be hiding life beneath its icy surface, the news about the new lake isexciting.“It would be great if these lakesharbored life,” Britney Schmidt, a planetary scientist who worked on the study,told Science News. “But even if they didnt, they say that Europa is doingsomething interesting and ac

11、tive right now.”Schmidt, a scientist at the University of Texas at Austin, and her colleagueswanted to know how chaos terrains form. Since they couldnt rocket to Europa tosee for themselves, they searched for similar formations here on Earth. Theystudied collapsed ice shelves in Antarctica and icy c

12、aps on volcanoes in Iceland. Thosefeatures on Earth formed when liquid water mixed with ice. The scientists nowsuspect something similar might be happening on Europa: that as water and iceof different temperatures mingle and shift, the surface fractures. This wouldexplain the jumbled ice sculptures.

13、“Fracturing catastrophically disruptsthe 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 becausing chaos terrains to form quickly on Europa.The new study suggests that on thismoon, elements such as oxygen f

17、es（惰性气体）1 Have you ever ridden on a balloon? Many tourist spots offer balloon rides inorder for people to see the beauty of a place from above. A balloon contains anoble gas called helium(氦). Formerly, balloons contained hydrogenbut hydrogen is very flammable and dangerous when uncontrolled. Therefo

18、re, peopleshifted to helium, which is safer. Helium is safe because it has the propertiesof the noble gases.2 People once believed that noble gases couldnt chemically react at all. Forthis reason, they were called inert gases(惰性气体). They werealso listed under Group 0 in theold periodic table because

19、 scientists believed that the gases have zero valence(价)electrons in their outer shell. This was later proven to be untrue when somenoble gas compounds were discovered.3 Thegases are elements, which share similar properties. These properties includebeing monoatomic, colorless, odorless, being able t

20、o conduct electricity, andhaving low chemical reactivity. Noble gases include Helium, Neon, Argon,Krypton, Xenon and Radon. These are all found in Group 18, in the rightmostcolumn of the periodic table. If you look at the periodic table, you willnotice that these elements are the only ones, which do

21、 not have a charge.Helium has the lowest molecular(分子的) weight whileRadon is the heaviest.4 Remember that chemical reactions occurbecause atoms have valence electrons, which are electrons in their outer shell.When the outer shell is “unfilled” or the required number of electrons is notyet complete,

22、the atom is more reactive. Noble gases have a full outer shell,meaning that they have complete electrons in their outer shell. This completenumber varies. For instance, the outer shell of Helium has 2 valence electronswhile the outer shell of Xenon has 8 electrons. Nowadays, there remains to be afew

23、 noble gases because of the low chemical reactivity of these said gases.A. what is theperiodic table?B. What are noblegases？C. What causes the lowchemical reactivity of noble gases?D. How were noblegases discovered?教育联展网 中国最实效的教育培训门户网站 www.theA.cn5E. How were noblegases understood in the past?F. wha

24、t are theapplications of noble gases?5because of their properties, noble gases have many importantapplications. 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 doctors

25、uspects that a persons brain has been damaged, he might request for MagneticResonance Imaging(MRI). MRI allows the doctor to “see” the brain, withoutoperating on the patient.23.paragraph 2_ E _24.paragraph 3_ B_25.paragraph 4_C_26.paragraph 5_F_27.Noble gases are not very chemicallyA28.Among the ele

27、 of many people in many countries. However, one countryresisted these changes. High in the Himalayan mountains of Asia, the kingdom of Bhutan remained separate. Its people andBuddhist(佛教)culture had not been affected for almost a thousand years. Bhutan,however, was a poor country. People died at a y

28、oung age. Most of its peoplecould not read, and they did not know much about the outside world. Then, in 1972,a new ruler named King Jigme Singye Wangchuck decided to help Bhutan tobecome modern, but without losing its traditions.King Wangchuck looked at other countriesfor ideas. He saw that most co

29、untries measured their progress by their GrossNational Product (GNP). The GNP measures products and money. When the number ofproducts sold increases, people say the country is making progress. KingWangchuck had a different idea for Bhutan. He wanted to measure hiscountrys progress by peoples happine

30、ss. If the peoples happiness increased,the king could say that Bhutanwas making progress. To decide if people were happier, he created a measurecalled Gross National Happiness (GNH).GNH is based on certain principles thatcreate happiness. People are happier if they have health care, education, andjo

31、bs. They are happier when they live in a healthy, protected environment. Theyare 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 increasedGNH in Bhutan.People are healthier and 教育联展网 中

32、国最实效的教育培训门户网站 www.theA.cn6are living longer. More people are educated andemployed. Teenty-five percent of the land has become national parks, and thecountry has almost no pollution. The Bhutanese continue to wear theirtraditional clothing and follow their ancient Buddhist customs. Bhutan has alsobec

33、ome a democracy. In 2008, King Wangchuck gave his power to his son. Althoughthe country still had a king, it held its first democratic elections that year.Bhutanhad political parties and political candidates for the first time. Finally, Bhutan hasconnected to the rest of the world through television

34、 and internet.Bhutanis a symbol for social progress. Many countries are now interested in Bhutans GNH.These countries are investigating their own ways to measure happiness. Theywant to create new policies that take care of their people, cultures, and land.Brazilmay be the nest country to use the pri

35、nciples of GNH. Brazilian leaders see theprinciples of GNH as a source of inspiration. Brazil is a large country with adiverse population. If happiness works as a measure of progress in Brazil, perhapsthe rest of the world will follow.31.Who was Jigme Singye Wangchuck?A. Apresident.B. A Buddhistprie

36、st.C. A king.D. A general.32.Apart from modernizing Bhutan,what else did Wangchuck want to do for Bhutan?A. To make itspopulation grow.B. To keep itseparate from the world.C. To keep its traditions and customs.D. To encourageits people to get rich.33.A country shows its progress with GNP byA. sellin

38、heir progress.B. workingtogether to develop a common scale to measure GNH.C. taking both Bhutan and Brazil as symbols for socialprogress.D. trying to find their own ways tomeasure happiness.第二篇DownloadKnowledge Directly to Your BrainFor the first time, researchers havebeen able to hack into the proc

39、ess of learning in the brain, using inducedbrain patterns to create a learned behavior. Its not quite as advanced as aninstant kung-fu download, and its not as sleek as cognitive inception, 教育联展网 中国最实效的教育培训门户网站 www.theA.cn7butits still an important finding that could lead to new teaching andrehabili

40、tation techniques.Future therapies could decode the brainactivity patterns of an athlete or a musician, and use them as a benchmark forteaching another person a new activity, according to the researchers.Scientists from BostonUniversity and ATR ComputationalNeuroscience Laboratories in Kyotoused fun

41、ctional magnetic resonance imaging, or fMRI, to study the learningprocess. They were examining the adult brains aptitude for visual perceptuallearning, or VPL, in which repetitive training improves a persons performanceon a particular task. Whether adults can do this as well as young people hasbeen

42、an ongoing debate in neuroscience.Led by BU neuroscientist Takeo Watanabe,researchers used a method called decoded fMRI neurofeedback to stimulate thevisual cortex. First they showed participants circles at differentorientations. Then they used fMRI to watch the participants brain activity.The resea

43、rchers were then able to train the participants to recreate thisvisual cortex activity.The volunteers were again placed in MRImachines and asked to visualize shapes of certain colors. The participants wereasked to “somehow regulate activity in the posterior part of the brain” to makea solid green di

44、sc as large as they could. They were told they would get a paidbonus proportional to the size of this disc, but they werent told anythingabout what the disc meant. The researchers watched the participants brainactivity and monitored the activation patterns in their visual cortices.“Participants can

45、be trained to control theoverall 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 werenot aware of what they were learning, the researchers said.“The most surprising thing in t

46、his study isthat mere inductions of neural activation patterns corresponding to a specificvisual feature led to visual performance improvement on the visual feature,without presenting the feature or subjects awareness of what was to be learned,”Watanabe said in a statement.Watanabe and colleagues sa

47、id this methodcan be a powerful tool.“It can incept a person to acquire newlearning, skills, or memory, or possibly to restore skills or knowledge thathas been damaged through accident, disease, or aging, without a personsawareness of what is learned or memorized,” they write.36. what have researche

48、rs been ableto do with the help of the study?A. Discover apersons learning process in the brain.B. Make a person know how to do something without learning.C. Set up different learning patterns for different people.D. Enable people to learn kung fu instantly.37. what helps aperson to do a particular
