1、河南安阳市2016高考英语阅读理解（二轮）演练题（附答案）【2016高考训练】阅读理解推理判断题。Expensive perfumes(香水) come in tiny bottles, but many hide a whale-sized secret. To perfect a particular smell, perfume-makers often use an ingredient that comes from sperm whales, called ambergris. But using ambergris, which helps a perfume last long

2、er, is strongly opposed by many people who think it is wrong to kill whales just so we can sweet, Joerg Bohlmann is neither a perfumer nor a whale expert, Hes a plant biologist at the University of British Columbia in Canada. But his discovery of a new plant gene(基因) might push whales out of the per

3、fume business.The gene comes from fir trees, found throughout North America and commonly used as Christmas trees. The trees produce a chemical that can be used in perfume in place of ambergrisbut with a catch.“Theres a problem that many people wouldnt consider. In the tree, the chemical is mixed wit

4、h many others. That makes separation a challenge,” Bohlmann says.”Its like trying to isolate sugar from a biscuit.”This is where science becomes useful. When Bohlmann learned that fir trees produce the ambergris-like chemical, he decided to use his gene know-how to find the instructions for how to m

5、ake the ambergris-substitute.Bohlmann found that gene and took it out of the tree cells. Then he did something that might sound strange to someone who doesnt work in genetics: Bohlmann put the gene from the tree into yeast(酵母) cells.Yeast may sound familiar because its used to make things like bread

6、, wine and beer. Biologists like to work tith yeast because it easily adopts new genes and changes its features and behavior. When Bohlmann put the fir tree into the yeast, the yeast started making the same chemical that had seen produced by the tree.Perfumers pay big money for ambergris because it

7、is a fixative, which means it holds a smell in place on a persons body.“Cheap perfumes smell good in the first hour or so and then everything it gone.” explains Bohlmann. “But expensive perfumes are much more stable. Their smell lasts much longer, for hours or even a day after you apply them.”The ne

8、w chemical, made from the tree genes, can be used as a fixative, too. And using yeast to make it is far cheaper than acquiring ambergris.Bohlmann admits he never thought hed get into the perfume business. But now, he says, producers have been calling to find out how to use his technology in mew perf

9、umes.1. It can be inferred from the passage that if a perfume contains ambergris, .A. Its user probably supports whale huntingB. Its smell will last for about an hourC. There will be a whale symbol on hourD. It is probably very expensive2. The underlined expression “with a catch” in Paragrph 3 means

10、 .A. Being difficult to hold B. having a hidden problemC. needing further testing D. being too similar3. According to the passage, why are yeast cells often used in genetic research? A. They can take on the characteristics of other genes B. They can reproduce much faster than other cells. C. They sh

11、are some of the qualities of plant genes. D. Theyre much cheaper to use than ambergris.4. What can we learn about Joerg Bohlmann from the passage? A. He is opposed to whale hunting. B. He made his discovery during Christmas. C. He has worked in the perfume industry for many years. D. He has previous

12、ly done genetic esearch.语篇解读 本文是一篇科普说明文。介绍了一种使香水香味持久的物质龙涎香，因这一物质来自于鲸，所以遭到人们的反对。科学家们发现一些树中的化学物质可以用来取代它，他们利用酵母菌成功制造出了这些化学物质。1. D 推理判断题。 根据第二段第二句以及倒数第三段可知，含有龙涎香的香水价格昂贵，故D项正确。2. B 词义猜测题。根据第四段中“Theres a problem that many people wouldnt consider.” 可知该词组意为”有隐含的问题“， 故选B项正确。3. A 细节理解题。根据第七段第二句可知，由于酵母菌容易吸收其他基

13、因，并将目的基因成功表达出来，故常被用于基因工程研究中，故A项正确。4. D 推理判断题。根据第二段最后一句及第三段表达的语境可知，Joerg Bohlmann 已经意识到，这些树中某些基因所产生的和其他物质可以被用于香水中以代替龙涎香，但是这些化学物质和其他物质混合在一起，难以分离，故可以断定，Joerg Bohlmann 曾经做过基因研究，故D项正确。 阅读下列5篇短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。【2014高考训练】Ashok Gadgil has spent the past three decades helping people in needand h

22、 increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows，but it cant get back out. This is what the greenhouse effect

23、 does to the earth .The heat and light can get through the atmosphere, but it cant get out As a result，the temperature rises.Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without it，the earth would be freezing，or

24、it would be burning hot. It would be freezing at night because we would not get the suns heat and light .During the day, especially during the summer,it would be burning because the sun would be up with no atmosphere to filter(过滤)it，so people，plants，and animals would be exposed to all the light and

25、heat.Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the each can get unusually warmer, and many plants，animalsand people will die. Plants would die because they would not be able to take the heat .This would cause us to have less fo

32、un into a brick wall. Despite countless warnings in recent years about the need to address a potential hunger crisis in poor countries and an energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the pa

33、st two years. And oil prices have increased more than three times since the start of 2004. These food-price increases, combined with increasing energy costs, will slow if not stop economic growth in many parts of the world and will even affect political stability. Practical solutions to these proble

34、ms do exist, but well have to start thinking ahead and acting globally. Here are three steps to ease the current food crisis and avoid the potential for a global crisis. The first is to promote the dramatic success of Malawi, a country in southern Africa, which three years ago established a special

35、fund to help its farmers get fertilizer and seeds with high productivity. Malawis harvest doubled after just one year. An international fund based on the Malawi model would cost a mere $10 per person annually in the rich world, or $10 billion altogether. Second, the U. S. and Europe should abandon t

36、heir policies of paying partly for the change of food into biofuels. The U. S. government gives farmers a taxpayer-financed payment of 51 cents per gallon of ethanol(乙醇) changed from corn. There may be a case for biofuels produced on lands that do not produce foodstree crops, grasses and wood produc

37、tsbut theres no case for the government to pay to put the worlds dinner into the gas tank. Third, we urgently need to weather-proof the worlds crops as soon and as effectively as possible. For a poor farmer, sometimes something as simple as a farm pondwhich collects rainwater to be used in dry weath

38、ercan make the difference between a good harvest and a bad one. The world has already committed to establishing a Climate Adaptation Fund to help poor regions climate-proof vital economic activities such as food production and health care but has not yet acted upon the promise. 1. An international f

39、und based on the Malawi model would.A. cost each of the developed countries $10 billion per yearB. aim to double the harvest in southern African countries in a yearC. decrease the food prices as well as the energy pricesD. give poor farmers access to fertilizer and highly productive seeds2. With the

40、 second step, the author expresses the idea that.A. it is not wise to change food crops into gasB. it is misleading to put tree crops into the gas tankC. we should get alternative forms of fuel in any wayD. biofuels should be developed on a large scale3. Which of the following is true according to t

41、he passage? A. A rain-collecting pond is a simple safeguard against by weather.B. A Climate Adaptation Fund has been established to help poor regions.C. The world has made a serious promise to build farm ponds.D. It makes a great difference whether we develop wood products or not.4. In the passage, the author calls on us to.A. slow down but not to stop economic growthB. develop tree crops, grasses and wood productsC. achieve economic growth and political stabilityD. act now so as to relieve the global food shortage【参考答案】47.1-4 DAAD
