英语阅读理解训练--生态环保类(附答案)

1、高考英语阅读理解专项训练生态环保类(一) The need to feed a growing population is putting much pressure on the worlds supply of water. With 97% of the worlds water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a wate

2、r shortage(短缺)seems strange to someone fortunate enough to live in a high rainfall country, many of the worlds agricultural industries experience constant water shortages.Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新

3、分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transp

4、orted from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers overuse of irrigati

5、on water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.Saudi Arabias attempts to grow wheat in desert areas have seen t

6、he pumping of huge quantities of irrigation water from underground reserves.

12、ad to do was catch them. Agreement was reached，and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didnt last long.The change was hardly

13、 noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.The villagers decided that they couldnt just wait to see the crops failing and the children getting weak.

19、landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution.The 16yearold Canadian high school student，Daniel Burd, from Waterloo Collegiate Institute, has discovered a way to make plastic bags degrade(分解) in as few as 3 months，a finding that

20、won him first prize at the CanadaWide Science Fair，a $10 000 prize，a $20 000 scholarship, and a chance to revolutionize a major environmental issue.Burds strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified,

21、 we could put them to work eating the plastic much faster than under normal conditions.With this goal in mind, he ground plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the

22、microbes work their magic for 3 months. Finally，he tested the resulting bacterial culture on plastic bags，exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed (暴露) to the live bacteria was 17% lighter than the control after six weeks.The inputs are cheap：mainta

23、ining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide. “Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got t

24、ired of it and I wanted to know what other people are doing with these plastic bags. The answer：not much. So I decided to do something myself.”said Daniel Burd.1.

28、 in the future. Some of the worlds leading cities are facing disasters like floods and heat waves.LondonLondons flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat of flooding，but it was only designed to last until 2030 and close once every two

29、or three years. About 21 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.There are 26 underground stations, 400 schools, 16 hospitals，an airport and 80

30、 billion worth of property in Londons flood risk area, so large scale flooding would be disastrous.ParisOver a six?week period in July and August 2008，more than 11400mainly elderly peopledied in France from dehydration (脱水) and extremely high body temperature in a deadly heat wave. Heat waves of sim

31、ilar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?One solution is to have air?conditioners installed in elderly care homes. But this is considered a short?term solution, as the increase in demand for electricity also incr

32、eases carbon emissions.In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower”， which uses a covering of bamboo to act as a natural air?conditioner.ShanghaiShanghai is the fastest growing city on Earth.

33、million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.An estimated 250,000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coal?fired power stations, but these emissio
