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 controll

9、ed 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, Ch

10、oset and his colleagues there began developing their own snake robots. Chosets team programmed robots to perform the same movements as real snakes, such as sliding and inching forward.

Black holes can be best described as a sort of vacuum, sucking up everyt

17、hing in space. 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

18、 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

19、 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 a black hole thats only a fraction of an

20、 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 plac

21、e. Orbits do not change because the newly formed black hole contains exactly the same amount of mass as when it was a star, only this time 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 Eins

22、teins 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 nearly impossible to detect black holes via a telescope. But astronomers continue to study galaxies, space and the solar

23、system to understand how black holes might evolve. It is possible that black holes can exist for millions of years, and later contribute to a bigger process in galaxies, which can eventually lead to creation of new entities. Scientists also credit black holes as helpful in learning how galaxies bega

What happens to the objects around a black hole?F. What are black holes made of?23. Paragraph 1 24. Paragraph 2 25. Paragraph 3 26. Par

Albert Einsteins theory of relativity helps to prove . A. the creation of new entitiesB. an explosion of huge starsC.

26、 the tiniest particleD. the same amount of massE. the existence of black holesF. a fraction of an inch第4部分：阅读理解（第31-45题，每题3分，共45分）下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每题确定1个最佳选项。第一篇Energy and Public LandsThe United States boasts substantial energy resources. Federal lands provide a good deal of U.S. energy pr

27、oduction; the U.S. Department of the Interior manages federal energy leasing, both on land and on the offshore Outer Continental Shelf. Production from these sources amounts to nearly 30 percent of total annual U.S. energy production. In 2000, 32 percent of U.S. oil, 35 percent of natural gas, and 3

28、7 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 U.S. oil reserves and 74 percent of undiscovered natural gas. Revenues from fed

29、eral oil, gas, and coal leasing provide significant returns to U.S. taxpayers as well as State governments. In 1999, for example, $553 million in oil and gas revenues were paid to the U.S. Treasury, and non-Indian coal leases accounted for over $304 million in revenues, of which 50 percent were paid

30、 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 lags

31、 behind conventional energy production, though the amount is still significant. For example, federal geothermal resources produce about 7.5 billion kilowatt-hours of electricity per year, 47 percent of all electricity generated from U.S. geothermal energy. There are 2,960 wind turbines on public lan

32、ds 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 U.S. thirst for energy and increasing public unease with dependence on foreign oil sources, pressure on the public lands to meet U.S. energy demands is intensifying. Public lands are available for energy development only after they have been evaluated through the land use
