河南开封2014高考英语完形填空、阅读理解增分训练04（解析）

1、河南开封2014高考英语完形填空、阅读理解增分训练04（解析）Nowadays, there is a heated debate on whether pollutants should be cleaned in the air. Cleaning up the air, while good for our lungs, could make global warming worse. And the pollutants still go up around the air, along with carbon dioxide.These pollutants are called a

2、erosols (气溶粒) and they include soot as well as mixtures of nitrogen(氮) and sulfur(硫) and other stuff into the air. Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air."

3、There are so many different kinds of aerosols," she says. "Some warm and some cool. But in fact, humans are giving out a lot of extra aerosols, and they tend to cool for the most part."The aerosols reflect sunlight back into space, or keep us cool. But it turns out that's not all

4、they do. These aerosols also influence how much carbon dioxide gets drawn out of the air by plants on land and in the sea."They can add nutrients, for example, to the oceans or to the land," Mahowald says. "But also while they're in the atmosphere they can change the climate, and

5、thus that also can influence the amount of carbon, the land or the ocean can take up. So there are quite a few different ways that aerosols can act on each other."Mahowald's results suggest that reducing those pollutants could be an even bigger problem than realized, when you consider that

6、aerosols help remove carbon dioxide from the air by encouraging plant growth. Hard numbers on this effect are highly uncertain at the moment, but this could turn out to be quite significant.And studying it is not easy because the effects aren't well understood. For example, nitrogen can be a fer

7、tilizer (肥料), but it can stop plant growing when nitrogen comes out of the air in acid form. Right now it seems like we're much more likely to clean up aerosol pollution, while increasing the amount of carbon dioxide in the air. So scientists, unfortunately, may have a chance to see whether this

8、 experiment on our planet should continue or not.36. From Paragraph 2, we know that .A. scientists have been aware of how aerosols workB. Natalie Mahowald is an expert in climateC. cleaning up the air is so popularD. pollutants are under control so far【答案】B【解析】细节理解题。由第二段第二句Natalie Mahowald的同位语a clim

9、ate researcher at Cornell University可知Natalie Mahowald是一个气候专家，故选B。37. What is Natalie Mahowald's opinion on those aerosols?A. Aerosols can influence each other in various ways.B. All the aerosols will cool the earth.C. Aerosols can add nutrients to human beings. D. Any kind of aerosols will warm

10、 the earth.【答案】A【解析】细节理解题。由第三段Some warm and some cool得知，BD选项错误, 与Some不符。从第五段的to the oceans，得知C也不对。由第五段最后一句aerosols can act on each other气溶粒可以以不同的方式相互影响，故选A。38. Why is it important for scientists to get accurate numbers according to the passage? A. Scientists have a chance to research them.B. They ca

11、n bring scientists much more benefit.C. Scientists can protect the earth from being pollutedD. They can help scientists understand the effects better. 【答案】D【解析】推理判断题。从第六段最后一句和第七段开头句可推出D正确。其他选项与题目没有直接的因果关系。它们能帮科学家更好地理解影响，故选D。39. What does the last sentence of the passage imply?A. Scientists will be i

12、n a dilemma.B. The experiment will be successful.C. Scientists will carry out the experiment.D. Scientists have difficulty in the experiment. 【答案】A【解析】词义猜测题。从第七段开头句和第八段最后一句should continue or not应不应该进行。说明研究的左右为难。故A最合适。而D选项属于事实题，不是暗示推理题。科学家左右为难，故选A。40. Which of the following can be the best title of t

13、his passage?A. Pollutants in the Air.B. The Experiment on the PlanetC. The Reason for Global Warming D. The Influence of Aerosols 【答案】D【解析】标题归纳题。全文以Aerosols为中心，说明它的影响。故D正确。其他选项要么范围太大要么太小，不够全面。气溶粒的影响，故选D。Teacher John Wise and his wife Doreen who emigrated to Tasmania 12 years ago, decided to revisit
