EThe 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（短缺）seems strange to someone fortunate enough to live in a high rainfull 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 seaons, the costs of water redistribution(重新分配)are very high. Notonly 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 many 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 ro countries with agricultural industries in areas dependent on irrigation（灌溉）. In Texas, farmers’ overuse of irrigation water be resulted in a 25% redcution of the water stores. In the Central Valley area of south eastern USA, a huge water engineering project provided water for farming in dry vallege, but much of the water use has been poorly managed.Saudi Arabia’s attempts to grow wheat in desert areas have been 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.72. From the first two paragraphs we learnt that _______.A.much of the world’s water is available for useB.people in high rainfll countries feel luckyC.the costs of water redistribution should be consideredD.water can be easily carried through pipes across the world

Electronic MailDuring the past few years,scientists all over the world have suddenly found themselves pro-ductively engaged in task they once spent their lives avoiding—writing,any kind of writing,but particularly letter writing. Encouraged by electronic mail's surprisingly high speed,convenience and economy,people who never before touched the stuff are regularly,skillfully,even cheerfully tapping out a great deal of correspondence.Electronic networks,woven into the fabric of scientific communication these days,are the route to colleagues in distant countries,shared data,bulletin boards and electronic journals.Any-one with a personal computer,a modern and the software to link computers over telephone lines can sign on.An estimated five million scientists have done so with more joining every day,most of them communicating through a bundle of interconnected domestic and foreign routes known col-lectively as the Internet,or net.E-mail is starting to edge out the fax,the telephone,overnight mail,and of course,land mail.It shrinks time and distance between scientific collaborators,in part because it is conven-iently asynchronous（异步的）( Writer can type while their colleagues across time zones sleep; their message will be waiting.).If it is not yet speeding discoveries,it is certainly accelerating communication.Jeremy Bernstein,the physicist and science writer,once called E-mail the physicist's umbili-cal cord（脐带）.Later other people,too,have been discovering its connective virtues. Physi-cists are using it;college students are using it;everybody is using it;and as a sign that it has come of age,the New Yorker has celebrated its liberating presence with a cartoon—an apprecia-tive dog seated at a keyboard,saying happily,“on the Internet,nobody knows you're a dog.” Why is a dog sitting before a computer keyboard in a cartoon published by New Yorkers?A: Even dogs are interested in the computer.B: E-mail has become very popular.C: Dogs are liberated from their usual duties.D: E-mai deprives dogs of their owners' love.

Deforestation and Desertification(沙漠化)
The Sahel zone lies between the Sahara desert and the fertile savannahs(热带大草原)of northern Nigeria and South Sudan. The word sahel comes from Arabic and means marginal or transitional ,and this is a good description of the semi-arid(半干旱) lands, which occupy much of the Western African countries of Mail, Mauritania, Niger ,and Chad.
Unfortunately, over the last century the Sahara desert has steadily crept southwards eating into once productive Sahel lands. United Nations surveys show that over 70 percent of the dry land in agriculture use in Africa has deteriorate dover the last 30 years. Droughts have become more severe, the most recent lasting over twenty years in parts of the Sahel region. The same process of desertification is taking place across southern Africa as the Kalahari desert advances into Botswana and parts of South Africa.
One of the major causes of this desert advance is poor agricultural land use, driven by the pressures of increasing population. Overgrazing一 keeping too many farm animals on the land一means that grasses and other plants cannot recover, and scarce water supplies are exhausted. Over cultivation一 trying to grow too many crops on poor land一 results in the soil becoming even less fertile and drier, and beginning to break up. Soil erosion (侵蚀) follows, and the land turns into desert.
Another cause of desertification is loss of tree cover. Trees are cut down for use as fuel and to clear land for agricultural use. Tree roots help to bind the soil together, to conserve moisture, and to provide a habitat for her plants and animals. When trees are cut down, the soil begins to dry and loosen, wind and rain erosion increase, other plant species die, and eventually the fertile top soil may be almost entirely lost, leaving only bare rock and dust.
The effects of loss of topsoil and increased drought are irreversible. They are, however, preventable. Careful conservation of tree cover and sustainable agricultural land use have been shown to halt deterioration of soils and lessen the effects of shortage of rainfall. One project in Kita in south-west Malifunded by UNDP has involved local communities in sustainable management offorest, while at the same time providing a viable(有活力的)agricultural economy. This may be a model for similar projects in other West African countries.

第三篇Book Shops in LondonLondoners are great readers.They buy vast numbers of newspapers and magazines and of books一specially paperbacks,which are still comparatively cheap in spite of ever-increasing rises inthe costs of printing. They still continue to buy"proper"books,too,printed on good paper and bound between hard covers.There are many streets in London containing shops which specialize in book-selling. Perhaps the best known of these is Charring Cross Road in the very heart of London.Here bookshops of all sorts and sizes are to be found,from the celebrated one which boasts of being"the biggest bookshop in the world"to the tiny,dusty little places which seem to have been left over from Dicken's time. Some of these shops stock,or will obtain,any kind of book,but many of them specialize in second-hand books,in art books,in foreign books,in books on philosophy,politics or any other of the myriad subjects about which books may be written.One shop in this area specializes solely in books about ballet.Although it may be the most convenient place for Londoners to buy books,Charring Cross Road is not the cheapest. For the really cheap second-hand volumes,the collector must venture off the beaten track,to Farringdon Road,for example,in the East Central district of London.Here there is nothing so grandiose as bookshops.Instead,the booksellers come along each morning and tip out their sacks of books on the small barrows（流动集售货车）which line the gutters（街沟）.And the collectors,some professional and some amateur, who have been waiting for them,pounce（一把抓住）upon the dusty cascaded（一叠叠图书）.In places like this one can still, occasionally, pick up for a few pence an old volume that may be worth many pounds.The book sellers on Farringdon Road________.A:keep fine bookshopsB:keep only small bookshopsC:sell books on handcartsD:sell the same books as the bookshops on Charring Cross Road
