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 nerve

7、s 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 of natural disasters hurricanes, tornadoes, flooding and wildfires, to name a few. But the most dangerous type of natural dis

8、aster, 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 may sound scary, but people dont feel many of the tremors because they happen in remote and unpopulated regions. Many quakes

9、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, was felt from central Georgia to southeastern Canada. In many urban areas, including Washington, D.C., and New York City (Wal

10、l Street shown), people crowded the streets while engineers inspected buildings. Credit: Wikimedia/Alex TabakScientists 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 ea

11、rthquakes. Altogether, USGS researchers use seismometers to identify and locate about 20,000 earthquakes each 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

12、 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 plates cover our planets surface like a jigsaw puzzle. Often, jagged edges of these plates temporarily lock together. When plate

13、s jostle and scrape past each other earthquakes occur. On average, tectonic plates move very slowly about the 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 subst

Many tourist spots offer balloon ride

18、s in order for people to see the beauty of a place from above. A balloon contains a noble gas called hellum(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

19、 properties of the noble gases.2 People once belleved 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

20、 outer shell. This was later proven to be untrue when some noble gas compounds were discovered.3 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

21、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 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 whil

22、e Radon is the heaviest.4 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,

23、 meaning that they have complete 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 thes

24、e said gases.5 because of 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 pers

25、ons brain has been damaged, he might request for Magnetic Resonance Imaging(MRI). MRI allows the doctor to “see” the brain, without operating on the patient.23. paragraph 2_24. paragraph 3_25. paragraph 4_26. paragraph 5_A.

28、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 of its

29、 people could 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 to become modern, but without losing its traditions.King Wangchuck looked at other countries for ideas. He saw that most countries measured

30、their progress by their Gross Natonal 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 the peop

31、les 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. They ar

32、e 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 living lon

33、ger. More people are educated and employed. Teenty-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, King Wangc

34、huck 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 is a symbol

35、 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 nest country to use the principles of GNH. Brazilian le

36、aders 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.C. A king.D. A gene

40、ost animals possess 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, lo

41、ng time ago that nature provides 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

42、案) dont go back to the time of Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century, 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

43、pigeons to figure out how they stayed 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 inve

44、ntors examined spinning sycamore (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 Cornetts fish

45、 submarine(潜水艇) actually looks 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 of animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump

46、 like grasshoppers(蚂蚱)- sounds shocking, doesnt it? But imagine how life would change if we could achieve that.36. Cats, monkeys and giraffes mentioned in paragraph 1 are examples to illustrateA. animals have skills that humans do not possess.B. they are highly-evolved species as humans.C. humans ca

47、n learn animals skills.D. they are skillful in different ways.37. Which of the following can be found in the archive gallery?A. History books.B. The Wright brothers sculpture.C. Leonardo da Vincis bird-like flying machines.D. First practical airplanes built in the late 19th century.38. What happened after the Wright brothers success?A.
