10、of greenhouse gases and other human activities.Its effects include warming global temperature,rising sea levels andexpansion of deserts in the subtropics(亚热带).Warming is expected to be greater over land than over the oceans and greatest in the Arctic,with the continuing loss of glaciers,permafrost a

11、nd sea ice.Other likely changes include more frequent extreme weather events including heat waves,droughts,heavy rainfall with floods,heavy snowfall and species extinction due to great change of temperature.Bad effects on humans include the threat to food security from decreasing crop yields and the

12、 loss of populated(有人口居住的)areas because of rising sea levels.Possible responses to global warming are reduction of emissions,adaptation to its effects,building systems resilient to its effects,and possible future climate engineering.Most countries are parties to the United Nations Framework Conventi

13、on on Climate Change UNFCCC),whose objective is to prevent dangerous climate change.It has adopted a range of policies designed to reduce greenhouse gas emissions and to assist in adaptation to global warming.It is agreed that future global warming should be limited to below 2.0 (3.6)relative to the

14、 pre-industrial level.On 12 November 2015,NASA scientists reported that human-made carbon dioxide continues to increase above levels that have not been seen in hundreds of thousands of years:currently,about half of the carbon dioxide releasedfrom the burning of fossil fuels remains in the atmosphere

15、 and is not absorbed by vegetation and the oceans.【文章大意】本文讲述了温室效应带来的影响,我们应该适应,并且要减少温室气体的排放以免它的加剧。1.What does the underlined word“resilient”mean?A.Be easily damaged.B.Be able to recover easily.C.Can be bent easily.D.Be difficult to change.【解析】选B。推理判断题。根据上下文语境可知,这里的系统是为了更容易地应对全球变暖的影响,故选B。2.Which of th

16、e following is NOT mentioned as an effect of global warming?A.Rising sea levels and expansion of deserts.B.More frequent extreme weather events.C.Species extinction.D.Increasing crop yields.【解析】选D。细节理解题。根据文中内容可知,只有D选项增加农作物产量没有涉及,故选D。3.Which of the following can be inferred from the last two paragrap

17、hs?A.It is likely for us to deal with global warming by reducing greenhouse gas emissions,adapting to its effects and climate engineering.B.There is no solution to too much carbon dioxide released into the atmosphere.C.It is common that human-made carbon dioxide keeps on increasing greatly in the pr

18、evious several centuries.D.Future global warming should be limited to below 3.6.【解析】选A。细节理解题。根据文中最后两段内容可知,我们应该减少温室气体排放,适应它带来的气候影响等,故选A。B Despite the long-term warming trend seen around the globe,the oceans have cooled in the last three years,scientists said.It suggests that global warming trends can

19、 sometimes take a break.In the last century,Earths temperature has risen about 1 degree Fahrenheit.Most scientists agree that much of the warming in the past 50 years has been caused by the burning of fossil fuels and other human activities,and most scientists expect the oceans will finally continue

20、 to warm in response to climate change humans have caused.This research suggests that global warming isnt always steady.The oceanstoday are still warmer than they were during the 1980s.Regardless of the cooling trend observed since 2003,average sea level has continued to rise.The rising of sea level

21、 occurs due to the thermal(热的)expansion of the oceans from the heating and run-off from melting ice sheets and glaciers.The recent cooling trend suggests sea level should have actually decreased in the past two years.Despite this,sea level has continued to rise.This may mean that the sea level rise

22、has recently changed from being mostly caused by warming to being controlled by melting.In a study before,researchers reported that in parts of the Antarctic,84 percent of glaciers have drawn back over the past 50 years in response to a warmer climate.But the melting glaciers are not the reason for

23、the cooling.The amount of ice and water from the melting glaciers is very small compared to the overall temperature of the oceans.Researchers have not yet known the cause of ocean cooling in the last three years but hope that further studies will make this unusual thing understood.【文章大意】本文是一篇说明文。短文介

24、绍了尽管全球出现了长期变暖的趋势,但海水温度反而降低。这表明,全球变暖的趋势有时会有所缓解。4.The underlined word“It”in the first paragraph refers to.A.the long-term warming trendB.Earths temperatureC.the cooling of the oceansD.climate change【解析】选C。词义猜测题。由第一段“Despite the long-term.a break.”可知,科学家们说,尽管全球出现了长期变暖的趋势,但在过去三年里,海洋温度已经冷却了。这表明,全球变暖的趋势有时

25、会有所缓解。所以根据上下文的语境,可以判断出这里的It指代的是“the cooling of the oceans”。5.According to the passage,how many causes are there leading to the sea level rise?A.One.B.Two.C.Three.D.Four.【解析】选B。细节理解题。由第四段“The rising of sea level occurs due to.glaciers”可知,海平面上升是由于海洋因热量增加而膨胀,以及冰盖和冰川融化导致的径流而造成的。所以根据文章可知,导致海平面上升的原因有两个。6.

26、Which of the following is TRUE according to the passage?A.Global warming will be worse and worse.B.The cause of ocean cooling isnt clear.C.Sea level has stopped rising for the past two years.D.The rising of sea level will cause many deaths.【解析】选B。细节理解题。由第六段“Researchers have not.in the last three yea

27、rs.”可知,研究人员还不知道过去三年海洋温度下降的原因。所以B选项“海洋温度下降的原因尚不清楚”符合文意。7.What would be the best title for the passage?A.The Rising of Sea LevelB.The Warming EarthC.The Oceans on EarthD.Global Warming Takes a Break【解析】选D。标题归纳题。通读全文尤其是第一段“Despite the long-term warming.a break.”可知,科学家们说,尽管全球出现了长期变暖的趋势,但在过去三年里,海洋温度已经下降。

28、这表明,全球变暖的趋势有时会有所缓解。以及下文解释了其他因素而不是全球变暖造成的地球温度上升和海平面上升,这些都在说明全球变暖的趋势有所缓解。故D选项“全球变暖的趋势有所缓解”为短文最佳标题。.阅读填句根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。If you work hard to have a positive attitude,you might be surprised by how much better you feel about yourself and life in general.1The less stress you feel,t
