The largest, a magnitude 5.6 quake, shook thousands of fans in a college football stadium, caused cracks in a few bui

7、ldings 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 of natural disasters hurricanes, tornadoes, flooding and wildfires, to name a few. But the most d

8、angerous 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 may sound scary, but people dont feel many of the tremors because they happen in remote and unpo

9、pulated 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, was felt from central Georgia to southeastern Canada. In many urban areas, including Washington

10、, D.C., and New York City (Wall Street shown), people crowded the streets while engineers inspected buildings. Credit: Wikimedia/Alex Tabak Scientists know about small, remote quakes only because of very sensitive electronic devices called seismometers. These devices detect and measure the size of g

11、round vibrations produced by earthquakes. 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 a

12、nd 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 plates cover our planets surface like a jigsaw puzzle. Often, jagged edges of these plates temp

18、s. The Greek philosophers believed that light was made up of countless, tiny particles that enter the human eye and create what we call vision. However, Empedocles and a Dutch scientist named Christian Huygens believed that light was like a wave. According to them, light spread out and travelled lik

19、e a straight line. This theory was accepted during the 19th century. 2 ln 1905, Albert Einstein published a research paper in which he explained what is referred to as the photoelectric effect. This theory explains that particles make up light. The particles Einstein was referring to are weightless

20、bundles（束）of electromagnetic（电磁）energy called photons（光子）. Today, scientists agree that light has a dual（二重） nature it is part particle and part wave. It is a form of energy that allows us to see things around us. 3 Things that give off light are known as sources of light. During the day, the primar

21、y source of light is the sun. Other sources of light include stars, flames, flashlights, street lamps and glowing gases in glass tube. 4 When we draw the way light travels we always use straight lines. This is because normally light rays travel in a straight line. However, there are some instances t

22、hat can change the path and even the nature of light. They are reflection, absorption, interference （干扰）, etc. 5 Physicists have attempted to measure the speed of light since the early times. In 1849, Hippolyte Fizeau conducted an experiment by directing a beam of light to a mirror located kilometer

23、s away and placed a rotating cogwheel（旋转齿轮）between the beam and the mirror. From the rate of rotation of the wheel, number of wheels teeth and distance of the mirror, he was able to calculate that the speed of light is 313 million meters per second. In a vacuum（真空）,however, the speed of light is 299

24、,792,458 meters per second. This is about a million times faster than the speed of an airplane. 23. Paragraph 2 _ 24. Paragraph 3 _ 25. Paragraph 4 _ 26. Paragraph 5 _ A.

27、 comes in tiny packages. New cell phones and personal computers get smaller every year, which means these electronics require even smaller components on the inside. Engineers are looking for creative ways to build these components, and theyve turned their eyes to graphene, a superthin material, made

28、 of carbon, that could change the future of electronics. This years Nobel Prize for Physics has been awarded to Andre Geim and Kostya Novoselov from the University of Manchester, UK. for the discovery of graphene. Graphene isnt just small, its “the thinnest possible material in this world.“ says Nov

29、oselov. He calls it a “wonder material.“ Its so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of ordinary white paper. If you were to hold a sheet of graphene in your fingers, youd have no idea because you wouldnt be able to see it. Carbon is one of th

30、e most abundant elements in the universe. Every known kind of life contains carbon. Graphene is a sheet of carbon, but only one atom thick. You dont have to look far to find grapheneits all around you. If you want this high-tech wonderstuff, all you need is a pencil, paper and a little adhesive tape

31、. Use the pencil to shade a small area on the paper, and then apply a small piece of adhesive tape over the area. When you pull up the tape, you11 see that it pulls up a thin layer of some of the shading from your pencil. That layer is called graphite, one of the softest minerals in the world. Now s

32、tick the same piece of tape on another sheet of paper and pull the tape up-there should be an even thinner layer, this time left on the paper. Now imagine that you do this over and over, until you get the thinnest possible layer of material on the paper. This layer would be only one atom thick, and

33、you wouldnt be able to see it. Graphite is made of layers of graphene. So when you get to the thinnest possible layer, youve found graphene. （分数：15.00）(1).What would change the future of electronics according to engineers? （分数：3.00）A.Personal computer.B.Big technology.C.Graphene.D.Creative ways.(2).

34、Which of the following statements about graphene is true ? （分数：3.00）A.It is visible to the human eye.B.It is possibly the thinnest material in the world.C.It can be used to make paper.D.Finding it demands time and money.(3).The word “apply” in paragraph 4 could be used to replaced by ? （分数：3.00）A.pu

37、ry and remarkable natural beauty, has a cuisine all its own. Immigration（移民） to the island has helped to shape its cuisine, with people from all over the world making various contributions to it. However, before the arrival of these immigrants, the Taino people lived on the island of Puerto Rico. Ta

38、ino cuisine included such foods as rodents (啮齿动物), fresh shellfish and fish fried in corn oil. Many aspects of Taino cuisine continue today in Puerto Rican cooking, but it has been heavily influenced by the Spanish, who invaded Puerto Rico in 1508, and Africans, who were initially brought to Puerto

39、Rico to work as slaves. Taino cooking styles were mixed with ideas brought by the Spanish and Africans to create new dishes. The Spanish extended food choices by bringing cattle, pigs, goats, and sheep to the island. Africans also added to the islands food culture by introducing powerful, contrastin

40、g tastes in dishes. In fact, much of the food Puerto Rico is now famous for - coffee, coconuts, and oranges - was actually imported by foreigners to the island. A common assumption many people make about Puerto Rican food is that it is very spicy(辛辣的). lts true that chili peppers are popular; aij ca

41、ballero in particular is a very hot chili pepper that Puerto Ricans enjoy. However, milder(微辣的) tastes are popular too, such as sofrito. As the base of many Puerto Rican dishes, sofrito is a sauce made from chopped onions, green bell peppers, sweet chili peppers, and a handful of other spices. It is

42、 fried in oil and then added to other dishes. （分数：15.00）(1).who lived in Puerto Rico first （分数：3.00）A.the AfricansB.the SpanishC.the AmericansD.the Taino people(2).In the first paragraph the word “it” refers to （分数：3.00）A.immigrationB.Caribbean historyC.the islands natural beautyD.Puerto Rican cuisi

45、chili peppersD.Aij caballero is a type of chile pepper第三篇 Archive Gallery: The Best of Bionics （仿生学） Humans might be the most highly-evolved species on the planet, but most animals possess skills we can only dream of having. Imagine how much electricity we could save if we could see in the dark the

46、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 provides the best blueprint（蓝图） for invention. Weve borrowed canals from beavers（河狸） and reflectors from c

47、ats 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 Leonardo da Vinci and his bird-like flying machines, but we can take you to the late 19th century

48、, 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 stayed high up when they were heavier than air. Their success inspired scores of successors to i

49、mprove 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 (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 like a fish.
