2、a experienced more than two dozen earthquakes. The largest, a magnitude 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 qu

3、akes. If you watch the news on TV, you see reports about all sorts of 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

4、 that several million earthquakes rattle the globe each year. That may 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 earthqu

5、ake that struck central Virginia the afternoon of August 23, 2011, was felt from central Georgia to southeastern Canada. In many urban areas, including Washington, D.C., and New York City (Wall Street shown), people crowded the streets while engineers inspected buildings. Credit: Wikimedia/Alex Taba

6、kScientists know about small, remote quakes only because of very sensitive electronic devices called seismometers. These devices detect and measure the size of ground vibrations produced by earthquakes. Altogether, USGS researchers use seismometers to identify and locate about 20,000 earthquakes eac

7、h year.Although earthquakes can happen anywhere in the world, really 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

8、 pieces of Earths crust, sometimes many kilometers thick. These plates cover our planets surface like a jigsaw puzzle. Often, jagged edges of these plates temporarily lock together. When plates jostle and scrape past each other earthquakes occur. On average, tectonic plates move very slowly about th

9、e same speed as your fingernails grow.But sometimes earthquakes rumble through portions of the landscape far from a plates edges. Although less expected, these “mid-plate” tremors can do substantial damage. Some of the biggest known examples rattled the eastern half of the United States two centurie

Many tourist spots offer balloon rides in order for people to see the beauty of a place from above. A balloon contains a noble

14、gas called helium. 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 gases.2. People once believed that noble gases couldnt chemically re

15、act 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 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.

16、 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, Argon, Krypton, Xenon and Radon. These are all found in Group 18, in the r

17、ightmost 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.4. Remember that chemical reactions occur because atoms have “valence” e

18、lectrons, 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 complete electrons in their outer shell. This complete number varies.

19、 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 inherent low chemical reactivity of these said gases.5. Because of their properties, noble gases have many important applica

20、tions. They are widely used in recreation, medicine and industries. For instance, Liquid Helium is used for superconducting magnets(磁体). These magnets are very important in physics and medicine.

24、ossess skills we 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 t

One of Orville Wrights pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined

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

35、parate. 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 Wangchuc

36、k 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 peop

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

38、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. Fi

Although the country still had a king, it held its first democratic elections that year. Bhutan had politic

Many countries are now interested in Bhutans GNH. These countries are investigating their own ways to measure happine

47、A, analyzed data from spacecraft Cassini, which pointed to the existence of methane-based form of life on Saturn's biggest moon.Scientists have reportedly discovered clues showing primitive alien beings are "breathing" in Titan's dense atmosphere filled with hydrogen.They argue tha

48、t hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane lakes and rivers.This, 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 Earth."We suggested hydrogen consumptio

49、n because it's the obvious gas for life to consume on 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

50、water-based life on Earth."To date, scientists have not yet detected this 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

51、), a methane-based organism would have to use a substance that is liquid as its medium for living processes, but not water itself.Water is frozen solid on Titan's surface and much too cold to support life as we know it.Scientists had expected the Sun's interactions with chemicals in the atmo
