科普知识阅读理解（3）科普知识（阅读理解）由 (2012四川,e)改编plants are flowering faster than scientists predicted (预测)in reaction to climate change,which could have long damaging effects on food chains and ecosystems.global warming is having a great effect on hundreds of plant and animal species around the world,changing some living patterns,scientists say.increased carbon dioxide(co2) in the air from burning coal and oil can have an effect on how plants produce oxygen,while higher temperatures and changeable rainfall patterns can change their patterns of growth.“predicting speciesreaction to climate change is a major challenge in ecology,”said the researchers of several u.s.universities.they said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.the study,published on the nature website,uses the findings from plant life cycle studies and experiments across four continents and 1,634 species.it found that some experiments had underestimated (低估) the speed of flowering by 8.5 times and leafing by 4 times.“across all species,the experiments under-predicted the speed of the advancefor both leafing and floweringthat results from temperature increases,”the study said.the design of future experiments may need to be improved to better predict how plants will react to climate change,it said.plants are necessary for life on the earth.they are the base of the food chain,using photosynthesis (光合作用)to produce sugar from carbon dioxide and water.they let out oxygen which is needed by nearly every organism on the planet.scientists believe the worlds average temperature has risen by about 0.8 since 1900,and nearly 0.2 every ten years since 1979.so far,efforts to cut emissions (排放) of planet-warming greenhouse gases are not seen as enough to prevent the earth heating up beyond 2 this centurya point scientists say will bring the danger of a changeable climate in which weather extremes are common,leading to drought,floods,crop failures and rising sea levels.1.what is the key information the author wants to give in paragraph 1?()a.plants reaction to weather could have damaging effects on ecosystems.b.the increasing speed of flowering is beyond scientistsexpectation.c.climate change leads to the change of food production patterns.d.food chains have been seriously damaged because of weather.2.we can learn from the study published on the nature website that .a.plants flowering is 8.5 times faster than leafingb.there are 1,634 plant species on the four continentsc.scientists should improve the design of the experimentsd.the experiments failed to predict how plants react to climate change3.scientists pay special attention to the study of plants because .a.they can prove the climate change clearlyb.they are very important in the food chainsc.they play a leading role in reducing global warmingd.they are growing and flowering much faster than before4.what can be inferred from the last two paragraphs about the worlds temperature?()a.it has risen nearly 0.2 since 1979.b.its change will lead to weather extremes.c.it is 0.8 higher in 1979 than that of 1900.d.it needs to be controlled within 2 in this century.语篇解读:本文为说明文,题材为科普知识类。温室效应已经影响了植物的生长类型,由于植物在食物链和生态系统中有着重要影响,科学家们正致力于研究其生长变化。答案及剖析:1.b主旨大意题。根据第一段plants are flowering faster than scientists predicted(预测)in reaction to climate change.可知本题应选择b项。2.c事实细节题。根据文章第五段最后一句话it found that some experiments had underestimated(低估)the speed of flowering.以及第七段the design of future experiments may need to be improved to better predict.可知本题应选择c项。3.b事实细节题。文章第四段最后一句they said plants had been the key object of study because their reaction to climate change could have an effect on food chains.由此可知本题选择b项。4.d推理判断题。根据文章最后一段.beyond 2 this century-a point scientists say will bring the danger of a changeable climate.leading to drought,floods.可知必须将上升温度控制在2 以内才可能不会出现危险状况,故选择d项。【长难句子分析】so

the danger of achangeable climate宾语in whichweather extremesare common,定语从句 leading to drought,floods,crop failures and rising sea levels.结果状语到目前为止,为减少导致全球变暖的温室气体排放的努力还不足以阻止地球在本世纪气温上升不超出2科学家认为这个数据会带来气候变化的危险,在这样的气候变化中,极端天气会经常发生,会导致干旱、洪涝、庄稼歉收和海平面上升。.阅读理解。阅读下列短文, 从给的四个选项 (a、b、c和d) 中, 选出最佳选项。【2014山东省潍坊市五校联合高三下学期期中考试】at times my mom

todays children likely to survive far longer than their parents or grandparents.of the 12.4 million children aged 16 and under,3.3 million (27%) will become someone who is a hundred years old or older.in a class of 30 children，eight can live to be 100.and the rest of the children are likely to get to an old age，even though they will not make it to three figures.experts warned that children may live to 100，but that they will not get their state pension until they are 70 or beyond.the state pension age is rising to 66 for both men and women by 2020，and the government has warned it will continue to rise.laith khalaf，a pension expert，said，“living to an old age is lucky if you can afford it，but a nuisance if you cant.those without enough savings will be depending on the state pension which will be changed.”it also increases the possibility of millions of people surviving until their 100th birthday with a poor quality of life because of poor health and little money.millions of older people have no pensions，no savings and no plans about how they are going to pay for their retirement other than to carry on working.if the older population demands more resources，then they have to come from their own wealth or the government.laith said，“millions of people will be spending over a third of their lives in retirement.it is high time that we reformed the state pension system.we
