A new study in West Africa shows how farm irrigation systems powered by the sun can produce more food and money for villagers. The study in Benin found that solar-powered pumps are effective in supplying water, especially during the long dry season.
Sub-Saharan Africa is the part of the world with the least food security. The United Nations Food and Agriculture Organization estimates that more than one billion of the world’s people faced hunger last year. Around two hundred sixty-five million of them live south of the Sahara Desert. Lack of rainfall is one of their main causes of food shortages.
Jennifer Burney from Stanford University in California led the study. The research team helped build three solar-powered irrigation systems in northern Benin.
The solar-powered irrigation systems produced an average of nearly two metric tons of vegetables per month.
They sold the surplus(过剩的) produce at local markets. The earnings greatly increased their ability to buy food during the dry season which can last six to nine months.
People in the two villages with the systems were able to eat three to five more serving of vegetables per day. But making the surplus available at markets also had a wider effect.
The study compared the villages with two others where women farmed with traditional methods like carrying water in buckets. The amount of vegetables eaten in those villages also increased, though not as much.
The researchers note that only four percent of the cropland in sub-Saharan Africa is irrigated. Using solar power to pump water has higher costs at first. But the study says it can be more economical in the long term than using fuels like gasoline, diesel or kerosene. And solar power is environmentally friendly.
1. People living in sub-Saharan Africa are short of food mainly because______.
A. it seldom rains there throughout the year B. there is little farmland in the area
C. people there lack experience in farming D. people know nothing about irrigation techniques
2. Which of the following is an advantage of Jennifer’s irrigation systems?
A. They are not affected by the weather.
B. They cost much less than traditional irrigation systems.
C. They have no bad effects on the environment.
D. They use less fuel than traditional irrigation systems.
3. We can learn from the last paragraph that______.
A. people in South Africa will soon be provided with enough food
B. the demand for fuels like gasoline will greatly decrease in Africa
C. people in sub-Saharan Africa don’t take agriculture seriously
D. it’s worthwhile to use the new irrigation systems on the while
4. People in the two villages owe all the following to Jennifer’s irrigation systems EXCEPT that ______.
A. they could buy more food during the dry season
B. they could eat more vegetables than usual every day
C. they could supply local markets with vegetables
D. they could provide people in other villages with food

In today’s throw away society, dealing with the city’s growing mountain of waste is an inereasing challenge for the city countil(市议会)。
Recently. Edinburgh is faced with the problem of dssposing of(处理)about250,000
Million tons of waster a year . Despite different ways to dispose of much of it in a green manner---largely through encouraging tecycling---its aging facilities such as the Powderhall landfill do not have the ability to deal with it.
The European Union(EU) has issued a new policy, regulating how such mountains of waster are to hr disposed of. The five councils (Edinburgh. East Lothian. West Lothian. Midlethian and Borders) face fine around $18million a year from 2013 it they don’t inerease recycling levels and rely less on landfill. With this in mind, the coumlls got together with the idea of building a lage incinerator plant (垃圾焚烧厂)to burn half of the waste produced in their districts. But the plan fell apart after the change of target levels by a new UK government waste policy which required that no more than 25% of the city’s waste should be disposed of in this way by 2025.
After the plan was abandoned, a private company which already transported millions of tons of the city’s wast by train to a landfill site near Dunbar, offered an alternative soution when it suggested opening a huge waste site near Portobello.
Since Powderhall is supposed to close in 2015, it seemed necessary for the members of the Edinburgh Council to accept the suggestion. But soon they turned it down—after 700 local objections reached them—because it would have meant hundreds of lorries a day making loud noise through heavily populated areas.
That still leaves eth council with a problem. By 2013,only50%of 1995 levels of waste will benllewed to be sent to landfill. Even if recveling large are met, there will still be a large amount of rubbish to be burnt up. Due build an Edinburgh and Midlothian councils have now decided to work together to build an ineinerator plant as time to find a solution is fast running out.
【小题1】The main way of handling waste in a green manmer in Edinburgh is .

There is no doubt that much of the profit of a business—sometimes the whole of its success—depends upon the use of the odds and ends.The odds and ends are various small things,which are left over when the main things are produced.But they possess a real value of their own.
If a business,big or small,looked down upon these odds and ends,it would mean a big difference in the amount of the benefit of the business.Take a meat factory for instance, there are countless odds and ends—bones and hair,which can be made into glue and rope to increase its profit greatly.
Then,if we are college students,what about our odds and ends—the odd moments? Take time for example.Every one of us has the exact same amount of it.Everyone's success or failure depends on the use of their time.But everyone uses the time more or less in the same way.However,why many great men in science or art have made huge successes for themselves in the world?Because they have made best use of their odd moments.Take Thomas A.Edison, he never allowed his odd moments to slip by.He thought,planned,and tried his inventions.He always worked twenty hours out of each twenty-four.His inventions made him famous all over the world,and provided valuable wealth for the human beings.
So, remember this axiom:very busy people always find time for everything.However,people with great spare time find time for nothing.Is it very strange?Not at all!The question is how to gather up fragments of time and make full use of them.As many big businesses have found,that the real profit is in using the odds and ends.We also must do in this way to make best use of our odd moments and manage to be successful in something that we do.
What are odds and ends?
A. They are nothing useful.
B. They are various small,but valuable things.
C. They are the main things that factories produce.
D. They are odd moments students deny to gather up.
Why should the odds and ends be made full use of ?Because ____ .
A. lots of factors in success or in failure depend on the best use of odds and ends
B. they control to possess a value of their own
C. they are various small things people don't want
D. they are useless things left over when the main things are produced
What does the word “Axiom” in the fourth paragraph mean?
A. clear and evident without proof
B. statement accepted as true without proof of argument
C. statement that can be argued
D. regulation accepted in scientific usage
“Fragments of time” equals “____ ”in the above passage.
A. the odds and ends B. immense leisure
C. the main things D. the odd moments
查看习题详情和答案>>Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.
One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill(废渣填埋场),the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste.The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.
Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.
Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.

Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.
| A. The reasons for the problematic food situation in Britain. B. The effect of the situation on farmers. C. The variety of British food. D. The surface richness of food and questions it brings. E. The different situations at home and abroad. F. The recent reason for the huge supply of food. |
| 1 |
The long years of food shortage in Britain have suddenly given way to huge food supply. Stores and shops are crowded with food. Rationing(定量供应) has already seemed too distant to today’s Britons. Even overseas suppliers have been asked to hold back deliveries. Yet, instead of joy, there is widespread uneasiness and worries. Why do food prices keep on rising, when there seems to be so much more food about? Is the surface huge amount of food only temporary, or has it come to stay? Does it mean that we need to think less now about producing more food at home?
| 2 |
The recent growth of food supply on the world food market has certainly been unexpectedly great, partly because two continuous big grain harvests in North America are now being followed by a third. Most of Britain’s overseas suppliers of meat, too, are offering more this year and home production has also risen.
| 3 |
Then why is the food situation in Britain still faulty? On the one hand, The British government has gradually cut down support for food. On the other hand, the shops are overstocked with food not only because there is more food available, but also because people, frightened by high prices, are buying less of it.
| 4 |
Moreover, the rise in food prices at home has come at a time when world prices have begun to fall, with the result that imported food, with the exception of grain, is often cheaper than the home-produced variety. And now grain prices, too, are falling internationally. British consumers are beginning to ask why they should not be able to benefit from this trend.
| 5 |
The significance of these developments is not lost on farmers. The older generation have seen it all happen before. Despite the present price and market guarantees, farmers fear they are about to be squeezed between cheap food imports and a smaller home market. Present production is running quickly compared with years ago. However, farmers haven’t shared any benefit from the change.
