But appearances can be deceiving: Mileswithin its cracked, fr
7、igid shell, Europa probably hides giant pools of 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 investigate the moons surface forclues to what lies beneath. In a new study, scientists in
8、vestigated one groupof 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
9、 “chaos terrains.” 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 s
10、uspect that Europaalso 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 doingsomethin
11、g interesting and active 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
12、 Antarctica and icy caps 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 ju
13、mbled ice sculptures. “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, el

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 hydrogenbu
18、t hydrogen is very flammable and dangerous when uncontrolled. Therefore, 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
19、). They werealso listed under Group 0 in theold periodic table because 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. Thes
20、e properties includebeing monoatomic, colorless, odorless, being able to 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 periodi
21、c table, you willnotice that these elements are the only ones, which do 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 shel
22、l is “unfilled” or the required number of electrons is notyet complete, 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
23、outer shell of Xenon has 8 electrons. Nowadays, there remains to be afew noble gases because of the low chemical reactivity of these said gases. 5because of their properties, noble gases have many importantapplications. They are widely used in medicine and industries. For instance,liquid Helium is u
24、sed for superconducting magnets(磁体).These magnets are very important in physics and medicine. When a doctorsuspects 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_ _

However, one countryresisted these changes. High in the Himalayan mountains of Asia, the kingdom of Bhutan remained se
28、parate. 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 young 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 Wangchu
29、ck decided to help Bhutan tobecome modern, but without losing its traditions. King Wangchuck looked at other countriesfor ideas. He saw that most countries measured their progress by their GrossNational Product (GNP). The GNP measures products and money. When the number ofproducts sold increases, pe
30、ople say the country is making progress. KingWangchuck had a different idea for Bhutan. He wanted to measure hiscountrys progress by peoples happiness. If the peoples happiness increased,the king could say that Bhutanwas making progress. To decide if people were happier, he created a measurecalled G
31、ross National Happiness (GNH). GNH is based on certain principles thatcreate happiness. People are happier if they have health care, education, andjobs. They are happier when they live in a healthy, protected environment. Theyare happier when they can keep their traditional culture and customs. Fina
32、lly,people are happier when they have a good, stable government. Now there is some evidence of increasedGNH in Bhutan.People are healthier and are living longer. More people are educated andemployed. Teenty-five percent of the land has become national parks, and thecountry has almost no pollution. T
33、he Bhutanese continue to wear theirtraditional clothing and follow their ancient Buddhist customs. Bhutan has alsobecome 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
34、and political candidates for the first time. Finally, Bhutan hasconnected to the rest of the world through television 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
35、to create new policies that take care of their people, cultures, and land. Brazilmay be the nest country to use the principles 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 progres

Its not quite as advanced as aninstant kung-f
40、u download, and its not as sleek as cognitive inception, butits still an important finding that could lead to new teaching andrehabilitation 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
41、activity, according to the researchers. Scientists from BostonUniversity and ATR ComputationalNeuroscience Laboratories in Kyotoused functional magnetic resonance imaging, or fMRI, to study the learningprocess. They were examining the adult brains aptitude for visual perceptuallearning, or VPL, in w
42、hich repetitive training improves a persons performanceon a particular task. Whether adults can do this as well as young people hasbeen an ongoing debate in neuroscience. Led by BU neuroscientist Takeo Watanabe,researchers used a method called decoded fMRI neurofeedback to stimulate thevisual cortex
43、. First they showed participants circles at differentorientations. Then they used fMRI to watch the participants brain activity.The researchers were then able to train the participants to recreate thisvisual cortex activity. The volunteers were again placed in MRImachines and asked to visualize shap
44、es of certain colors. The participants wereasked to “somehow regulate activity in the posterior part of the brain” to makea solid green disc 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
45、. The researchers watched the participants brainactivity and monitored the activation patterns in their visual cortices. “Participants can 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
46、 region.” This worked even when test subjects werenot aware of what they were learning, the researchers said. “The most surprising thing in this study isthat mere inductions of neural activation patterns corresponding to a specificvisual feature led to visual performance improvement on the visual fe
47、ature,without presenting the feature or subjects awareness of what was to be learned,”Watanabe said in a statement. Watanabe and colleagues said 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 be
48、en damaged through accident, disease, or aging, without a personsawareness of what is learned or memorized,” they write. （分数：15.00）(1).what have researchers been ableto do with the help of the study? （分数：3.00）A.Discover apersons learning process in the brain.B.Make a person know how to do something
49、without learning.C.Set up different learning patterns for different people.D.Enable people to learn kung fu instantly.(2). what helps aperson to do a particular task better in visual perceptual learning? （分数：3.00）A.TestingB.EncouragementC.Self- assessmentD.Repetition(3).which of thefollowing statements is true of the experiment participants? （分数：3.00）A.They learned how to control MRL machines in the experimentB.They werenot told what to be learned in the experimentC.They were paid to take p
