27、Too Little for Global WarmingOil 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 di

28、oxide 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

29、up the shortfall. But all agree that burning coal would be even worse for the planet.The IPCCs 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

30、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 ga

31、s 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

32、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 worlds remaining reserves.Nebojsa Nakicenovic, an energy economist at the University of Vienna, Austria who head

33、ed the 80-strong IPCC team that produced the forecasts, says the panels 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, “theres a huge amount of coal underground that co

34、uld 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

35、 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 Earths doomsday.B. The oil reserves are big enough to materialize the doomsday scenariosC. Melting ice

36、 caps and searing temperatures exist only in science fictionD. Oil and gas will run out so fast that Earths doomsday will never materialize.32. Nations that signed the Kyoto Protocol agree toA. pay attention to global meltdownB. cut CO2 emissionsC. use more green energyD. stop using fossil fuels33.

37、What are the estimates of the worlds oil and gas reserves?A. 4,000 billion barrels by the average forecastB. 8,000 billion barrels estimated by the SwedesC. 3,500 barrels envisaged by IPCCD. 3,500 billion by a growing number of scientists34. Which of the following about Nebojsa Nakicenovic is true?A

38、. he thinks fossil fuels are as dirty as oil and gasB. he thinks green fuels will replace oil and gas eventuallyC. he thinks IPCCs view on the worlds reserves is too optimisticD. he thinks that IPCCs estimates are more optimistic than the Swedes35. Which of the following is the near explanation of N

39、akicenovics 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 problemsC. Oil and gas to replace coal as fuel would speed up the process of gl

40、obal warmingD. A switch from the IPCC scenarios to the policymakers ones would be disastrous 第二篇Listening to BirdsongA 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 differen

41、ce 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.Scientis

42、ts had noticed slight variations in the songs of mal zebra fmches 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. Wo

43、olley 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

44、 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 didnt. The females shifted around a bit, and then most of

45、 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 theyd 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 spe

46、nt more time listening to the concert version of their mates songs. This suggests that after a while, females learn to recognize-and preferthe 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 conce

47、rt songs. These brain areas may be involved in recognizing and evaluating the songs, and storing the memories of them.This research deals with whats 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 highpitched4 sing-song chatter, and the babies respond best to those sounds. Songbirds are one of the only other species known to lear
