Section Ⅲ　Integrated skills Ⅰ.阅读理解 　　Several years ago， Jason Box， a scientist from Ohio， flew 31 giant rolls of white plastic to a glacier （冰川） in Greenland.He and his team spread them across 10，000 feet of ice， and then left.His idea was that the white blanket would reflect back the rays of the sun， keeping the ice cool below.When he came back to check the results，he found it worked.Exposed ice had melted faster than covered ice.He had not only saved two feet of glacier in a short time.No coal plants （火电厂） were shut down， no jobs were lost， and nobody was taxed or fired.Just the sort of fix we’re looking for. 　�———�Thank you， but no thank you，” says Ralph King， a climate scientist.He told Grey Childs， an author and commentator， that people think technology can save the planet， but there are other things we need to deal with， like consumption.They burned $ 50，000 just for the helicopter to bring the plastic to the glacier.This experiment， quote-unquote， gives people false hope that climate change can be fixed without changing human behavior.It can’t.Technology won’t give us a free ride. 　　Individuals respond to climate change differently.Climatologist Kelly Smith is hardly alone in her prediction that some day soon we won’t be climate victims （受害者） — we will be climate choosers.More scientists agree with her that if the human race survives， the engineers will get smarter， the tools will get better， and one day we will control the climate.But that then？ “Just the mention of us controlling the climate sent a small shiver down my back，” Grey writes.“Something sounded wrong about stopping ice by our own will，” he says. 　　Me？ I like it better when the earth takes care of itself， I guess one day we will have to run the place， but for the moment， sitting at my desk， looking out at the trees bending wildly and the wind howling， I’m happy not to be in charge. 1.Why does the author mention Jason Box’s experiment in the first paragraph？（　　） A.To introduce a possible solution to climate change. B.To describe a misleading attempt to fix the climate. C.To report on a successful experiment on saving the glacier. D.To arouse people’s attention to the problem of global warming. 2.Which statement would Ralph King most probably agree with？（　　） A.The experiment against climate change will not succeed. B.Technology is not the final solution， let alone its high cost. C.It’s best to deal with climate change without changing our behavior. D.Jason’s experiment plays a significant role in fixing climate change. 3.Which of the following words has the similar meaning to the underlined word in Paragraph 3？（　　） A.Relief. B.Click. C.Shake. D.Description. 4.Which of the following is a suitable title for the text？（　　） A.But Should We Fix the Climate？ B.Is Climate Change a Real Problem？ C.How Can We Take Care of the Earth？ D.What If All the Glaciers Disappeared？ Ⅱ.阅读七选五 　　 ... ...
