California Gives Green Light to Space Solar Power
      Energy beamed down from space is one step closer to reality, now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatts of power beamed down from solar-power satellites beginning in . But some major challenges will have to be overcome if the technology is to be used widely.
      A start-up company called Solaren is designing the satellites, which it says will use radio waves to beam energy down to a receiving station on Earth.
      The attraction of collecting solar power in space is the almost uninterrupted sunshine available in geosynchronous orbit. Earth-based solar cells, by contrast, can only collect sunlight during daytime and when skies are clear.
      But space-based solar power must grapple with the high cost per kilogram of launching things into space, says Richard Schwartz of Purdue University in West Lafayette, Indiana. “If you're talking about it being economically viable for power of the Earth, it's a tough go,” he says.
      Cal Boerman, Solaren’s director of energy services, says the company designed its satellites with a view to keeping launch costs down. “We knew we had to come up with a different, revolutionary design,” he says. A patent the company has won describes ways to reduce the system's weight, including using inflatable mirrors to focus sunlight on solar cells, so a smaller number can collect the same amount of energy.
      But using mirrors introduces other challenges, including keeping the solar cells from overheating, says Schwartz. “You have to take care of heat dissipation because you’re now concentrating a lot of energy in one place,” he says. According to the company's patent, Solaren's solar cells will be connected to radiators to help keep them cool.
     Though Boerman says the company believes it can make space-based solar power work, it is not expecting to crowd out other forms of renewable energy. Laws in California and other states require increasing use of renewable energy in coming years, he points out. “To meet those needs, we're going to need all types of renewable energy sources,” he says.

16. Solar-power satellites will use radio waves to beam energy down from space.
A. Right. B. Wrong C. Not mentioned
17. Solaren is going to design 200 solar-power satellites.
A. Right. B. Wrong C. Not mentioned
18. Space-based solar cells could collect solar power only when skies are clear.
A. Right. B. Wrong C. Not mentioned
19. One advantage of space-based solar power system is that it is economical.
A. Right. B. Wrong C. Not mentioned
20. Inflatable mirrors are used to reduce the weight of the space-based solar power system.
A. Right. B. Wrong C. Not mentioned
21. 6.Space-based solar power will rule out other forms of renewable energy source.
A. Right. B. Wrong C. Not mentioned
22. Many countries will grant permission for the use of the space-based solar power system.
A. Right. B. Wrong C. Not mentioned

第3部分：概括大意与完成句子（第23-30题，每题1分，共8分）
下面的短文有2项测试任务：（1）第23-26题要求从所给的6个选项中为第1—4段每段选择1个最佳标题；（2）第27—30题要求从所给的6个选项中为每个句子确定1个最佳选项。
The Natural Gas
     Natural gas is produced from reservoirs deep beneath the earth surface. It’s a fossil fuel, meaning that it is derived from organic material buried in the earth millions of years ago. The main component of natural gas is methane.
     The popularity and use of clean natural gas has increased dramatically over the past 50 years as pipeline infrastructure has been installed to deliver it conveniently and economically to millions of residential, commercial and industrial customers world wide. Today, natural gas service is available in all 50 states in the U.S. and is the leading energy choice for fueling American homes and industries. More than 65 million American homes use natural gas. In fact, natural gas is the most economical source for home energy needs, costing one third as much as electricity. In addition to heating homes, much of the gas used in the U.S. is used as a raw material to manufacture a wild variety of products, from paint, to fibers for clothing, to plastics for healthcare, computing and furnishings. Natural gas is also used in a significant number of new electricity-generating power plants.
     Natural gas is one of the safest and cleanest fuels available. It emits less pollution than other fossil fuel sources. When natural gas is burned, it produces mostly carbon dioxide and water vapor—the same substances emitted when humans breathe. Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted—making natural gas the cleanest burning fossil fuel of all.
     The U.S. consumes about one third of the world’s natural gas output, making it the largest gas-consuming region in the world. The U.S. Department of Energy’s Energy Information Administration forecasts that natural gas demand will grow by more than 50 percent by 2025.
     There are huge reserves of natural gas beneath the earth’s surface. The largest reserves of natural gas can be formed in Russia, West and North Africa and the Middle East. LNG has been produced domestically and imported in the U.S. for more than four decades. Today, the leading importers of LNG are Japan, Korea, France and Spain.
23. Paragraph 2 ___.
24. Paragraph 3 ___.
25. Paragraph 4 ___.
26. Paragraph 5 ___.

A: Popularity and use of natural gas
B. Natural gas reserves and supply
C. Natural gas prices
D. Clean fuel of choice
E. Disadvantages of natural gas
F: Natural gas consumption

27. Natural gas is stored deep _______.
28. Natural gas is recognized as the most economical energy resource _______.
29. When manufacturing many different products, people use natural gas ________.
30. It is estimated by 2025 the natural gas demand in the US will increase ________.

A. over the past 50 years
B. beneath the earth surface
C. by more than 50 percent
D. for more than four decades
E. as a raw material
F. for home energy needs

第4部分：阅读理解（第39-53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
Too Little for Global Warming
　　Oil and gas will run out too fast for doomsday global warming scenarios to materialize, according to a controversial new analysis presented this week at the University of Uppsala in Sweden. The authors warn that all the fuel will be burnt before there is enough carbon dioxide in the atmosphere to realize predictions of melting ice caps and searing temperatures. Defending their predictions, scientists from the Intergovernmental Panel on Climate Change say they considered a range of estimates of oil and gas reserves, and point out that coal-burning could easily make up the shortfall. But all agree that burning coal would be even worse for the planet.
　　The IPCC's predictions of global meltdown pushed forward the 1997 Kyoto Protocol, an agreement obliging signatory nations to cut CO2 emissions. The IPCC considered a range of future scenarios, from unlimited burning of fossil-fuels to a fast transition towards greener energy sources. But geologists Anders Sivertsson, Kjell Aleklett and Colin Campbell of Uppsala University say there is not enough oil and gas left even the most conservative of the 40 IPCC scenarios to come to pass.
　　Although estimates of oil and gas reserves vary widely, the researchers are part of a growing group of experts who believe that oil supplies will peak as soon as , and gas soon after. Their analysis suggests that oil and gas reserves combined about to the equivalent of about 3,500 billion barrels of oil considerably less than the 5,000 billion barrels estimated in the most optimistic model envisaged by the IPCC. Even the average forecast of about 8,000 billion barrels is more than twice the Swedish estimate of the world's remaining reserves.
　　Nebojsa Nakicenovic, an energy economist at the University of Vienna, Austria who headed the 80-strong IPCC team that produced the forecasts, says the panel's work still stands. He says they factored in a much broader and internationally accepted range of oil and gas estimates than the “conservative” Swedes.
　　Even if oil and gas run out, “there's a huge amount of coal underground that could be exploited”, he says that burning coal could make the IPCC scenarios come true, but points out that such a switch would be disastrous. Coal is dirtier than oil and gas and produces more CO2 for each unit of energy, as well as releasing large amounts of particulates. He says the latest analysis is a “shot across the bows” for policy makers.
　　31. What do the authors of the new analysis presented at the University of Uppsala intend to say?
　　A. the burning of coal will accelerate the arrival of Earth's doomsday.
　　B. The oil reserves are big enough to materialize the doomsday scenarios
　　C. Melting ice caps and searing temperatures exist only in science fiction
　　D. Oil and gas will run out so fast that Earth's doomsday will never materialize.

32. Nations that signed the Kyoto Protocol agree to
　　A. pay attention to global meltdown
　　B. cut CO2 emissions
　　C. use more green energy
　　D. stop using fossil fuels

33. What are the estimates of the world's oil and gas reserves?
　　A. 4,000 billion barrels by the average forecast
　　B. 8,000 billion barrels estimated by the Swedes
　　C. 3,500 barrels envisaged by IPCC
　　D. 3,500 billion by a growing number of scientists

34. Which of the following about Nebojsa Nakicenovic is true?
　　A. he thinks fossil fuels are as dirty as oil and gas
　　B. he thinks green fuels will replace oil and gas eventually
　　C. he thinks IPCC's view on the world's reserves is too optimistic
D. he thinks that IPCC's estimates are more optimistic than the Swedes

35. Which of the following is the near explanation of Nakicenovic's assertion that “…… such a switch would be disastrous……?
　　A. The IPCC scenarios would come true because burning coal will emit larger amounts of CO2“
　　B. A switch to burning coal would produce disastrous environmental problems
　　C. Oil and gas to replace coal as fuel would speed up the process of global warming
　　D. A switch from the IPCC scenarios to the policymakers' ones would be disastrous

Listening to Birdsong
A male zebra finch1 chirps away2to himself. Suddenly he notices a female bird nearby. He realizes he has an audience and immediately changes his song. Can the female tell the difference in his performance? According to a new study, the female zebra finch knows. And she prefers the special trills he creates when he sings to her. A male zebra finch changes his song when singing to a female in ways that people can barely detect. But ~the female finch can tell the difference.
　　Scientists had noticed slight variations in the songs of mal~ zebra f'mches based on whether they were singing alone or whether there was a female (and potential mate) nearby. With an audience, the males sped up the pace of their songs and controlled the notes they used.
　　For this study, researchers Sarah C. Woolley and Allison Doupe at the University of California, San Francisco decided to focus attention on the listening females, which have not been well studied in the past.
　　In the study, Woolley and Doupe set up ,a long cage with a sound speaker at each end. One broadcast the sound of a male zebra finch singing to himself, like someone singing in the shower. The other speaker broadcast a male performing for a female audience, as if he was giving a concert.
　　Female birds were placed between the two speakers. Some of the birds had mates, others didn't. The females shifted around a bit, and then most of them hopped over to sit beside just one speaker. All the birds that made a clear choice liked songs meant for a female audience, even if they'd never met the male.
　　Mated females also had a chance to listen to two different performance songs, one from an unknown male, and one from their mate. They spent more time listening to the concert version of their mates' songs. This suggests that after a while, females learn to recognize--and prefer—the songs of their mates.
　　Scientists then studied the brains of the females. They found certain areas of the brain perked up3 when the birds listened to the concert songs. These brain areas may be involved in recognizing and evaluating the songs, and storing the memories of them.
　　This research deals with what's called directed communication, when the communicator, or sender, focuses the message for a specific audience. One example is the way moms speak to their babies. Mothers around the world use the same sort of high'pitched4 sing-song chatter, and the babies respond best to those sounds. Songbirds are
