The largest, a magnit

7、ude 5.6 quake, shook thousands of fans in a college football stadium, caused cracks in a few buildings and rattled the nerves of many people who had never felt a quake before. Oklahoma is not an area of the country famous for its quakes. If you watch the news on TV, you see reports about all sorts o

8、f natural disasters hurricanes, tornadoes, flooding and wildfires, to name a few. But the most dangerous type of natural disaster, and also the most unpredictable, is the earthquake.Researchers at the U.S. Geological Survey estimate that several million earthquakes rattle the globe each year. That m

9、ay sound scary, but people dont feel many of the tremors because they happen in remote and unpopulated regions. Many quakes happen under the ocean, and others have a very small magnitude, or shaking intensity.A magnitude 5.8 earthquake that struck central Virginia the afternoon of August 23, 2011, w

Altogether, USGS researchers use seismometers to identify and locate about 20,000 earthquakes each year.Although earthquakes can happen anywhere in the world, really

12、 big quakes occur only in certain areas. The largest ones register a magnitude 8 or higher and happen, on average, only once each year. Such big ones typically occur along the edges of Earths tectonic plates.Tectonic plates are huge pieces of Earths crust, sometimes many kilometers thick. These plat

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

19、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 gases.2. People once believed that noble gases couldnt chemically react at all. For this reason, they were called in

20、ert gases. They were also clustered under Group 0 in the old periodic table because scientists believed that 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 pro

21、perties. These properties include being monoatomic, colorless, odorless, being able to conduct electricity, 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 lo

22、ok 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.4. Remember that chemical reactions occur because atoms have “valence” electrons, which are electrons in their outer she

23、ll. 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 complete electrons in their outer shell. This complete number varies. For instance, the outer shell of Helium has 2 v

24、alence electrons while the outer shell of Xenon has 8 electrons. Nowadays, there remains to be a few noble 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, medic

25、ine 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 damaged, he might request for Magnetic Resonance Imaging (MRI). MRI allows the doctor to “see” the b

29、can only dream of having. Imagine how much electricity we could save if we could see in the dark the way cats do. Imagine leaping from tree to tree like a monkey. Giraffes(长颈鹿), which are otherwise calm and good-natured, sleep only 4.6 hours a day.We realized a long, long time ago that nature provid

30、es the best blueprint(蓝图)for invention. Weve borrowed canals from beavers(河狸)and reflectors from cats eyes. Although the words “bionics” became popular only after the 1960s, history shows that nature has always provided ideas on solving everyday problems. Our archives（档案）dont go back to the time of

31、Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19thcentury, where we applied those same principles for building our first practical airplanes.To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they s

32、tayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wrights pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore

33、(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter.Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic (简单抽象艺术) structure. On the other hand, Barney Connetts fish submarine (潜水艇) actually looks

34、like a fish.Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(蚂蚱)-sounds shoc

However，one country resisted these changes. High in the Himalayan mountains of Asia，the kingdom of Bhutan remained

40、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 of 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 Wangch

41、uck 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 measured their progress by their Gross Natonal Product（GNP）. The GNP measures products and money. When the number of products sold increases pe

42、ople 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 the peoples happiness increased，the king could say that Bhutan was making progress. To decide if people were happier，he created a measure calle

43、d Gross National Happiness（GNH）.GNH is based on certain principles that create happiness. People are happier if they have health care, education, and jobs. They are happier when they live in a healthy, protected environment. They are happier when they can keep their traditional culture and customs.

44、Finally, people are happier when they have a good, stable government.Now these is some evidence of increased GNH in Bhutan. People are healthier and are living longer. More people are educated and employed. Teenty-five percent of the land has become national parks, and the country has almost no poll

45、ution. The Bhutanese continue to wear their traditional clothing and follow their ancient Buddhist customs. Bhutan has also become a democracy. In 2008, 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 polit

46、ical parties and political candidates for the first time. Finally, Bhutan has connected to the rest of the world through television and internet.Bhutan is a symbol for social progress. Many countries are now interested in Bhutans GNH. These countries are investigating their own ways to measure happi

47、ness. They want to create new policies that take care of their people, cultures, and land.Brazil may be the nest country to use the principles of GNH. 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

53、ore hitting Titans planet-like surface covered with methane lakes and riversThis, they say, points to the existence of some bugs consuming the hydrogen at the surface of the moon less than half the size of the EarthWe suggested hydrogen consumption because its the obvious gas for life to consume on

54、Titan, similar to the way we consume oxygen on Earth, says NASA scientist Chris McKay. If these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth.To date, scientists have not yet detected th

55、is form of life anywhere, though there are liquid-water-based microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan, where temperatures are around 90 Kelvin (minus 290 degreesFahrenheit), a methane-based organism would have to use a substance that is liquid as

56、its medium for living processes, but not water itselfWater is frozen solid on Titans surface and much too cold to support life as we know it.Scientists had expected the Suns interactions with chemicals in the atmosphere to produce a coating of acetylene on Titans surfaceBut Cassini detected no acety

57、lene on the surface.The absence of detectable acetylene on the Titans surface can very well have a non-biological explanation, said Mark Allen, a principal investigator of the NASA Titan team.Scientific conservatism suggests that a biological explanation should be the last choice after all non-biolo

58、gical explanations are addressed.Allen saidWe have a lot of work to do to rule out possible non-biological explanationsIt is more likely that a chemical process, without biology, can explain these results.41. What do scientists claim to have found about Saturn?A. Water-based life on it.B. Methanebased life on its biggest moon.C. A new moon moving around it.D. Earthlike life on its biggest moon.【博大考神答案】：B42. Which of the
