| 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 whole | |||
| 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 | |||

| The need to feed a growing population is putting much pressure on the world"s supply of water. With 97% of the world"s 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 water shortage seems strange to someone fortunate enough to live in a high rainfall country, many of the world"s 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 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 transported 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. In Texas, farmers" overuse of irrigation 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 Arabia"s attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry. | |||
| 1. From the first two paragraphs we learn that _______. | |||
| A. much of the world"s water is available for use B. people in high rainfall countries feel lucky C. water can be easily carried through pipes across the world D. the costs of water redistribution should be considered . | |||
| 2. Which of the following is true? | |||
| A. The underground water in Saudi Arabia might run out in 50 years. B. Most industries in the world suffer from water shortages. C. The water stores in Texas have been reduced by 75%. D. Good management of water use resulted from the project in the Central Valley. | |||
| 3. The text is mainly about _______. | |||
| A. water supply and increasing population B. water redistribution and wildlife protection C. water use management and agriculture D. water shortages and environmental protection | |||
| 4. What is most likely to be discussed in the paragraph that follows? | |||
| A. Approaches to handling the pressure on water supply. B. Ways to reduce the costs of building dams. C. Measures to deal with worldwide water shortages. D. Steps to improving water use management | |||

| Modern inventions have speeded up people"s lives amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boasts (吹嘘) of saving precious seconds in handling tasks. All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind in another time zone. Again, spending too long at computer results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientists; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about. However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world. There was a time when some people"s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestors faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence. | |||
