These researchers tinker(修补)with machines in the lab and write computer software to control these devices. “Theyre the best toys out there，”says Howle Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist，a person who designs，builds or programs robots. When Choset was a kid，he was interested in anything that movedcars，trains，animals. He put motors on Tinkertoy 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，Chosets 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 bagan developing their own snake robots. Chosets 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 dont，such as rolling. Chosets 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 patients 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 they tested the robot in pigs. A company called Medrobotics in Boston is now adapting the technology to surgeries on people. Even after 15 years of working with his teams creations, I still dont 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 didnt begin developing his own snake robots until he started working Carnegie Mellon.

Scientists have discovered that black holes come from an explosion of huge stars. Stars that are near death can no longer burn due to loss of fuel，and because its temperature can no longer control the gravitational(重力的)force，hydrogen ends up putting pressure onto the stars surface until it suddenly explodes then collapses. 2 Black holes come from stars that are made of hydrogen，other gases and a few metals. When these explode it can turn into a stellar-mass(恒星质量)black hole，which can only occur if the star is large enough(should be bigger than the sun)for the explosion to break it into pieces，and the gravity starts to compact every piece into the tiniest particle. Try to see and compare：if a star thats ten times the size of the sun ends up being a black hole thats no longer than 70 kilometers，then the Earth would become black hole thats only a fraction of an inch! 3 Objects that get sucked in a black hole will always remain there，never to break free. But remember that black holes can only gobble up(吞噬)objects within a specific distance to it. Its possible for a large star near the sun to become a black hole，but the sun will continue to stay in place. Orbits(轨道)do not change because the newly formed black hole contains exactly the same amount of mass as when it was a star，only this its mass is totally contracted that it can end up as no bigger than a state. 4 So far，astronomers have figured out that black holes exist because of Albert Einsteins theory of relativity. In the end，through numerous studies，they have discovered that black holes truly exist. Since black holes trap light and do not give off light，it is not possible to detect black holes via a telescope. But astronomers continue to explore galaxies(银河系)，space and the solar system to understand how black holes. It is possible that black holes can exist for millions of years，and later contribute further process in galaxies，which can eventually lead to creation of new entities. Scientists also credit black holes as helpful in learning how galaxies began to form. A. What happens to the objects around a black hole? B. Is there proof that black holes really exist? C. How were black holes named? D. What are different types of black holes? E. What are black holes made of? F. How are black holes formed? 23. Paragraph 1 F 24. Paragraph 2 E 25. Paragraph 3 A 26.

Albert Einsteins theory of relativity helps to prove_A_ . A. the existence of black holes B. the creation of new entities C. the same amount of mass D. an explosion of huge stars E. a fraction of an inch F. the tiniest particle 参考答案：FEABDFCA 第4局部：阅读理解(第3145题，每题3分，共45分)下面有3篇短文，每篇短文后有5道题。 第一篇 Energy and Public Lands The United States boasts substantial energy resources. Federal lands provide a good deal of US energy production，the US Department of the Interior manages federal energy leasing(租赁)，both on land and on the offshore Outer Continental Shelf。 Production from these sources amounts to nearly 30 percent of total annual US energy production. In 2023，32 percent of US oil，35 percent of natural gas，and 37 percent of coal were produced from federal lands，representing 20,000 producing oil and gas leases and 135 producing coal leases. Federal lands are also estimated to contain approximately 68 percent of all undiscovered US oil reserves and 74 percent of undiscovered natural gas. Revenues from federal oil，gas，and coal leasing provide significant returns to US taxpayers as well as State Government. In 1999，for example，$553 million in oil and gas revenues were paid to the US Treasury，and non-India coal leases accounted for over $304 million in revenues，of which 50 percent were paid to State governments. Public lands also play a critical role in energy delivery. Each year，federal land managers authorize rights of way for transmission lines，rail systems，pipelines，and other facilities related to energy production and use. Alternative energy production from federal lands falls behind conventional energy production，though the amount is still significant. For example，federal geothermal(地热)resources produce about 7.5 billion kilowatt-hours(千瓦时)of electricity per year，47 percent of all electricity generated from US geothermal energy. There are 2,960 wind turbines on public lands in California alone，producing electricity for about 300,000 people. Federal hydropower facilities produce about 17 percent of all hydropower produced in the United States. Because of the growing US thirst for energy and increasing public unease with influence on foreign off sources，pressure on public lands to meet US energy demand is becoming more intense. Public lands are available for energy development only after they have been evaluated through the land use planning process. If development of energy resources conflicts with management or use of other resources，development restrictions or impact moderation measures may be enforced，or mineral be banned altogether. 31. What is the main idea of this passage? A. Public lands are one of the main sources of revenues. B. Public lands play an important role in energy production. C. Public lands should be developed to ease energy shortage. D. Public lands store huge energy resources for further development. 32. Which of the following statements is true of public lands in the U.S.? A. The majority of undiscovered natural gas is stored there. B. Half of US energy is produced there. C. Most of coal was produced from there in 2023. D. Most energy resources are reserved there. 33. Geothermal resources，wind turbines，and hydropower facilities in Paragraph 4 cited as examples to illustrate that A. the amount of alternative energy production from public lands is huge. B. alternative energy production is no less than conventional energy production. C. they are the most typical conventional energy resources from public lands. D. geothermal resources are more important than the other two。 34. There is a mounting pressure on public lands to satisfy US energy demands A. the U.S. is demanding more and more energy. B. many Americans are unhappy with energy development in foreign countries. C. quite a few public lands are banned for energy development. D. many Americans think public lands are being abused. 35. Public lands can be used for energy development when A. energy development restrictions are effective. B. federal land managers grant permissions. C. they go through the land use planning process. D. there is enough federal budget. 参考答案：BAAAC 其次篇 Putting Plants to Work Using the power of the sun is nothing new. People have had solar-powered calculators and buildings with solar panels(太阳能电池板)for decades. But plants are the real experts. Theyve been using sunlight as an energy source for billions of years. Cells in the green leaves of plants work like tiny factories to convert sunlight，carbon dioxide(二氧化碳)，and water into sugars and starches(淀粉)，stored energy that the plants can use. This conversion process is called photosynthesis(光合作用). Unfortunately，unless youre a plant，its difficult and expensive to convert sunlight into storable energy. Thats why scientists are taking a closer look at exactly how plants do it. Some scientists are trying to get plants，or biological cells that act like plants，to work as very small photosynthesis power stations. For example，Maria Ghirardi of the National Renewable Energy Laboratory in Golden. Colo.，is working with green algae(水藻). Shes trying to trick them into producing hydrogen instead of sugars when they perform photosynthesis. Once the researchers can get the algae working efficiently，the hydrogen that they produce could be used to power fuel cells in cars or to generate electricity. The algae are grown in narrow-necked glass bottles to produce hydrogen in the lab. During photosynthesis，plants normally make sugars or starches.“But under certain conditions，a lot of algae are able to use the sunlight energy not to store starch，but to make hydrogen.”Ghirardi says. For example，algae will produce hydrogen in an airfree environment. Its the oxygen in the air that prevents algae from making hydrogen most of the time. Working in an airfree environment，however，is difficult. Its not a practical way to produce cheap energy. But Ghirardi and her colleagues have discovered that by removing a chemical called sulfate(硫酸盐)from the environment that the algae grow in，they will make hydrogen instead of sugars，even when air is present. Unfortunately, removing the sulfate also makes the algaes cells work very slowly, and not much hydrogen is produced. Still, the researchers see this as a first step in their goal to produce hydrogen efficiently from algae. With more work, they may be able to speed the cellsactivity and produce larger quantities of hydrogen. The researchers hope that algae will one day be an easy-to-use fuel source. The organisms are cheap to get and to feed, Ghirardi says, and they can grow almost anywhere： “You can grow them in a reactor, in a pond. You can grow them in the ocean. Theres a
