16.A.A shocking report B.Solution to the terrifying result C.What is global warming? D.Many shocking things were found. E.Greater danger of extinction F.A careful analysis biologically |
The earth is getting warmer.People burn coal,oil and gas and this produces carbon dioxide,methane (沼气) and nitrous oxide.These gases,called"greenhouse gases",prevent the heat of the sun from leaving the earth's upper atmosphere and this makes the earth warmer.
82.A
A few weeks ago a group of scientists produced a report about global warming and the natural world.They wanted to find out if global warming was dangerous for plants and animals.According to what they found,the scientists say that during the next 50years about 25% of land animals and plants will become extinct.More than a million plant and animal species will be extinct by 2050.
83.B
More than 10% of all plants and animals will become extinct.It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere.But the scientists say if we control greenhouse gases now,we could save many more plants and animals from extinction.
84.F
The scientists studied some regions of the world with a very rich biology.These were Europe,Australia,Central and South America,and South Africa.Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill,to get cooler.In flat areas,such as deserts,plants and animals would have to move a very long distance to get cooler,so they are in greater danger of extinction.
85.D
The scientists found that half of the 24species of butterflies they studied in Australia would soon become extinct.60% of the species in the Kruger National Park in South Africa would also die out,and more than 100% of the 300South Africa plant species they studied would also become extinct.One of the plants in danger of extinction is the national flower of South Africa,the King Protea.They studied 163tree species in the Cerrado region of Brazil and found that 70would become extinct.Many of the plants and trees that live in the region live nowhere else in the world.In Mexico,they studied 1,870species and found that more than 30% of these were in danger of extinction.
分析 本文主要介绍了全球气温变暖的情况和一些惊人的事实.比如:在未来50年内会有25%的动植物会灭绝,在澳大利亚的24种蝴蝶的一半会灭绝等.
解答 81--85 CABFD
81.C 考查上下文理解判断能力.本段是对全球气温变暖进行解释.故选C.
82.A 考查上下文理解判断能力.根据下文A few weeks ago a group of scientists produced a report about global warming and the natural world可知,会列举一些相关的数据,在未来50年内会有25%的动植物会灭绝,前文应是:一个令人吃惊的报告.故选A.
83.B 考查上下文理解判断能力.根据本段最后一句But the scientists say if we control greenhouse gases now,we could save many more plants and animals from extinction可知,控制温室气体,可以拯救更多的动植物免于灭绝.即:是对可怕结果的解决办法.故选C.
84.F 考查上下文理解判断能力.根据下文The scientists studied some regions of the world with a very rich biology可知,是从生物角度的仔细分析.故选F.
85.D 考查上下文理解判断能力.本段里面出现了很多数据,都是发现的让人震惊的事情.故选D.
点评 七选五题型看似简单,实际上有时完全作对并不容易,需要方法和分析能力及足够的耐力,有必要进行专门练习.首先,快速浏览一遍七个备选答案,先确定哪个选项适合放在文章的什么位置.其次,快速浏览文章,确定文章体裁,抓住文章结构,分析篇章结构,找出各段的主题句或主旨大意.其三,注意各选项中出现的句子衔接手段,寻找句中衔接标志词,七选五备选答案中有两个多余的选项,会对文章中两个空的选择构成干扰,这时要特别细致地比对相似选项.最后,用代入法,检查答案是否合理,将所有选择答案放回空白处,通读全文,检查文章内容是否语义连贯合理、紧扣主题,语篇结构是否通顺连贯、具有一致性、合乎逻辑,写作思路是否清晰明了,格式以及用语是否恰当贴切,从而判断选择的答案是否正确.
