Climate change will force exhausted birds migrating to Europe from Africa to travel further with possibly disastrous consequences，according to a study.The annual voyage of some species，which fly north in search of food and suitable habitats.could increase by as much as 400 kilometers(250 miles)，the research found.“Marathon migrations for some birds are set to become even longer，”said Stephen Willis, a professor at Durham University in Britain and the main architect of the study.“This is bad news for birds like the Whitethroat，a common farmland bird.The added distance is a considerable threat.As temperatures rise and habitats change，birds will face their biggest challenge since the Pleistocene era(更新世：始于距今180万年)，which ended 11，000 years ago，”he said in a statement.Some 500 million birds migrate each year from Africa，some weighing as little as nine grams. (threetenths of an ounce)To complete a voyage that can be thousands of kilometers long，birds have to fatten themselves up to twice their normal weight.Some even shrink their internal organs (收缩内脏)to become more fuel efficient，so any additional distance may be dangerous.The study finds that from 2071 to 2100，nine out of 17 species examined are going to face longer migrations，particularly birds that cross the Sahara Desert.Some birds traverse the Sahara and the Mediterranean Sea in a onego，while others have a break in northern Africa before crossing.Many fly at night，when temperatures are cooler.A fewsuch as the Blackcaphave started to adapt by spending winters in Britain，but such behaviour remains exceptional，the study said.The study forecasts that the migration distance of the Orphean Warbler will jump from 2，700 kilometers(1，700 miles)to between 3，050 and 3，350 kilometers(1，900 and 2，1 00miles)，with even longer increases for the Subalpine and Barred Warblers.1What does travelling extra distance mean for some migrating birds?ABetter living conditions.BBetter physical health.CStronger ability to fly.DBigger threat to life.2To complete the marathon migrations，some birds have to do the following except_Ahave a break in SaharaBput on more weightCreduce the size of internal organsDfly at night to avoid the heat3What does the underlined word“traverse”in the fourth paragraph mean?AExamine.BFace.CCross.DChallenge.4What can we infer from the text?ABirds have to migrate from Africa to Europe in winter.BGlobal warming is bad for all birds worldwide.CBirds that are of small size dont need to migrate.DSome birds have to migrate unless they adapt to climate change.5Whats the BEST title of the text?

Studies by leading research institutions have shown that if we invest in clean energy over fossil fuels, we will create more American jobs. A report released by the United Steelworkers and the Sierra Club, for example, found that thanks to the growth of wind energy, about 5，200 manufacturing jobs could be created in Iowa alone over the next decade. Additional studies have found that thousands more jobs could be created in other states that have suffered industry job losses and that welcome the opportunity to train workers for the new energy economy.But, in order to fully transit to a clean energy economy，we need our elected officials to take action. Without policies from the government, the private field may continue to invest in oldfashioned, polluting technologies. More than 70 coal plants without technology to capture carbon pollution are now being considered. If these projects go ahead, this will be billions of dollars invested in technology that is outdated and not “clean coal”. We need effective policies to push growing clean energy industries forward.Each of us can play a role in bringing about this muchneeded transition. Tell your business and elected leaders that the next generation deserves to grow up in a world powered by clean energy. Tell your mayor that you want city planning that encourages more efficient new buildings and sidewalks and bike paths that make it easy to walk or ride a bike. Tell your state and national officials to invest in energy grids (电力网) that can deliver renewable energy to everyone. Tell your company that instead of oldstyle coal power you want to buy solar, wind, or geothermal energy. Tell your elected officials that you want national policies that encourage investors to make longterm commitments to clean energy.1The underlined part “a transformation” in Paragraph 1 refers to “_”Aa change from fossil fuels to clean energyBa choice for fossil fuelsCa chance of developing modern industriesDa choice for global warming2According to Paragraph 2, a clean energy economy_Ahas helped develop more wind energyBis quite beneficial to ordinary peopleChas developed fast in most states of the USDis valued by the governments around the world3Which of the following is a major concern to the government according to the passage?AInvestments in clean energy.BCoal plants without advanced technology.CTechnology for capturing carbon pollution.DPolicies on the good use of clean energy.4What is Paragraph 4 mainly about?AEveryone can contribute to the clean energy.BCitizens have the right to talk to the mayor.CElected leaders should be responsible for the next generation.DMore investments should be put into energy grids.5If this passage is taken from a newspaper, in which part would you most probably find it?ACulture.BSociety.CEconomy.DNature.BBeijing had its biggest snowfall since 1951.Britain is suffering through its longest cold snap(寒潮)since 1981.And freezing weather is hitting the Deep South，including Floridas orange groves and beaches.Whatever happened to global warming?Such weather doesnt seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases.But experts say the cold snap doesnt contradict global warming at allits just a temporary phenomenon in the longterm heating trend.“Its part of natural variability，”said Gerald Meehl，a senior scientist.With global warming，he said，“well still have record cold temperatures.Well just have fewer of them.”Scientists sa
