第19、20、21、22、23、24、25题:Where Has the Salt Come from? Every now and then, we meet a fact about our earth that makes us feel strange and no answer for the fact has yet been found. Such a fact is the existence of salt in the oceans. How did it get there? We simply do not know how the salt got into the ocean! We do know, of course, that salt is water-soluble, and so passes into the oceans with rainwater. The salt of the earth's surface is constantly being dissolved (溶解) and is passing into the ocean. But we do not know whether this can explain the huge quantity of salt in oceans, if all the oceans were dried up, enough salt would be left to build a wall 180 miles high and a mile thick. Such a wall would reach once around the world at the Equator (赤道)! The common salt that we all use is produced from seawater or the water of salt lakes, from salt springs (源泉) and from deposits of rock salt. The concentration (浓度) of salt in seawater ranges from about three per cent to three-and-one-half percent. The Dead Sea, which covers an area of about 340 square miles, contains about 11,600,000,000 tons of salt! On the average, a gallon (加仑) of seawater contains about a quarter of a pound of salt. The beds of rock salt that are found in various parts of the world were all originally formed by the evaporation (蒸发) of seawater millions of years ago. It is believed that the thick rock-salt deposits were formed after about nine-tenth of the volume of seawater had been evaporated. Most commercial salt is obtained from rock salt. The usual method is to drill wells (井) down to the salt beds. Pure "water is pumped down (抽进去) through a pipe. The water dissolves the salt and it is forced through another pipe up to the surface. 16 We have not fully understood how salt got into the ocean. A Right B Wrong C Not mentioned 17 The author is sure that the dissolved salt from the earth's surface is the only source of the huge quantity of salt found in oceans. A Right B Wrong C Not mentioned 18 If all the oceans were dried up, the salt thus obtained would be extremely great in size. A Right B Wrong C Not mentioned 19 The percentage of salt content in the Red Sea is higher than that in the Dead Sea. A Right B Wrong C Not mentioned 20 Beds of rock salt are found in every part of the world. A Right B Wrong C Not mentioned 21 After evaporation, about ten percent of seawater becomes rock salt. A Right B Wrong C Not mentioned 22 Most commercial salt is obtained from seawater. A Right B Wrong C Not mentioned |

第26、27、28、29、30、31、32题: Mad Scientist Stereotype OutdatedDo people still imagine a physicist as a beardedman in glasses or has the image of the mad scientist changed? The Institute ofPhysics set out to find out whether the stereotype of a physics 'boffin' (科学家)still exists by conducting asurvey on shoppers in London. The people were asked to identify the physicistfrom a photograph of a line-up of possible suspects. 98 percent of those askedgot it wrong. The majority of people picked a white male of around 60, wearingglasses and with a white beard. |

第33、34、35、36、37、38、39题: Wide World of Robots Engineers who build and program robots have fascinating jobs. These researchers tinker (修补) with machines in the lab and write computer software to control these devices. "They're the best toys out there," says Howie Choset at Carnegie Mellon University in Pittsburgh. Choset is a robotics, a person who designs, builds or programs robots. When Choset was a kid, he was interested in anything that moved — cars, trains, animals. He put motors on Tinker toy cars to make them move. Later, in high school, he built mobile robots similar to small cars. Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Choset's labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist (扭曲) in many directions and travel over a lot of different types of terrain (地形). "Snakes are far more interesting than the cars," Choset concluded. After he started working at Carnegie Mellon, Choset and his colleagues there began developing their own snake robots. Choset's team programmed robots to perform the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually don't, such as rolling. Choset's snake robots could crawl (爬行) through the grass, swim in a pond and even climb a flagpole. But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient's chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake? Choset teamed up with Marco Zenati, a heart surgeon now at Harvard Medical School, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and then tested the robot in pigs. A company called Medrobotics in Boston is now adapting the technology for surgeries on people. Even after 15 years of working with his team's creations, "I still don't get bored of watching the motion of my robots," Choset says. 16. Choset began to build robots in high school. A. Right B. Wrong C. Not mentioned 17. Snake robots could move in only four directions. A. Right B. Wrong C. Not mentioned 18. Choset didn't begin developing his own snake robots until he started working at Carnegie Mellon. A. Right B. Wrong C. Not mentioned 19. Choset's snake robots could make more movements than the ones others developed. A. Right B. Wrong C. Not mentioned 20. The application of a thin robotic snake makes heart surgeries less time-consuming. A. Right B. Wrong C. Not mentioned 21. Zenati tested the robot on people after using it in pigs. A. Right B. Wrong C. Not mentioned 22. The robotic technology for surgeries on people has brought a handsome profit to Medrobotics. A. Right B. Wrong C. Not mentioned |

第41、42、43、44、45、46、47题: A Great Quake Coining? Everyone who lives in San Francisco knows that earthquakes are common in the Bay Area — and they can be devastating. In 1906, for example, a major quake destroyed about 28.000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when the next “Big One” will strike. It’s bound to happen someday. At least seven active fault (断层) lines run through the San Francisco area. Faults are places where pieces of Earth’s crust(地壳)slide past each other. When these pieces slip, the ground shakes. To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens. One new finding about the 1906 quake is that the San Andreas fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture (断裂) at about 2. 7 kilometers per second. During bigger quakes, however, ruptures can happen at rates faster than 3. 5 kilometers per second. At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco, these pressure pulses (脉冲) traveled away from the city during the 1906 event. As bad as the damage was, it could have been far worse. Looking ahead, scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent. New buildings in San Francisco are quite safe in ease of future quakes. Still, more than 84 percent of the city’s buildings are old and weak. Analyses suggest that another massive earthquake would cause extensive damage. People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while. According to the new research, however, it’s not a matter of “if” the Big One will hit. It’s just a matter of when. 16.The San Francisco area is located above several active fault lines. A. Right B. Wrong C. Not mentioned 17.The 1906 earthquake in San Francisco is the most severe one in American history. A. Right B. Wrong C. Not mentioned 18.The highest speed of fault ruptures in the 1906 quake was more than 3.5 kilometers per second. A. Right B. Wrong C. Not mentioned 19.Earthquakes rarely happened in San Francisco before 1906. A. Right B. Wrong C. Not mentioned 20.San Francisco is fully prepared for another big earthquake. A. Right B. Wrong C. Not mentioned 21.Scientists will be able to predict the exact time of an earthquake soon. A. Right B. Wrong C. Not mentioned 22.A major earthquake striking San Francisco someday is inevitable. A. Right B. Wrong C. Not mentioned |
