BThe world is not only hungry,it is also thirsty for water. this may seem strange to you,since nearly 75% of the earth is covered with water. But about 97% of this water is sea water.Man can only drink and use the other 3% fresh water that comes from rivers,lakes,under-ground and other places. And we cannot even use all of that,because some of this fresh water has been made dirty.At the moment,this small amount(数量) of fresh water is still enough for us. However,our need for water is getting greater and greater. Only if we take steps to solve this problem now,we can get away from a serious world water shortage later on. The people of the world cannot have an enjoyable life without enough clean water.On one hand we should stop wasting this little water of ours,on the other hand we should find ways to reuse it,but this has not been done widely.Today,in most large cities,water is used only once and it then returns to the sea or runs into underground places.lf we can make it clean again,it can be used once more just as if it were fresh from a spring.But even if large cities reuse its water,we still would not have enough in the future. Where.could we turn to next for water? To the ocean! How can we do to make use of this great a-mount of sea water? We can take the salt from the water to make it fresh.So if we take all these steps,we'll be in no danger of drying up!( )26. Why does the writer say that the world is thirsty for water?A. The amount of fresh water is really very small.B. The people of the world waste too much water.C. The people of the world have to drink a lot of water every day.D. There are too many people in the world needing water.

共用题干第二篇Natural MedicinesSince earliest days,humans have used some kinds of medicines.We know this because humans have survived.Ancient treatments for injury and disease were successful enough to keep humans from dying out completely.They were successful long before the time of modern medicine.Before the time of doctors with white coats and shiny(发亮的)instruments. Before the time of big hospitals with strange and wonderful equipment.Many parts of the world still do not have university-educated doctors. Nor do they have expensive hospi- tals.Yet injuries are treated.And diseases are often cured.How?By ancient methods.By medicines that might seem mysterious , even magical(有魔力的).Traditional medicines are neither mysterious nor magical, however.Through the centuries, tribal(部族的)medicine men experimented with plants. They found many use- ful chemicals in the plants.And scientists believe many of these traditional medicines may provide the cure for some of today's most serious diseases.Experts say almost 80% of the people in the world use plants for health care.These natural medicines are used not just because people have no other form of treatment.They are used because people trust them. In developed areas,few people think about the source of the medicines they buy in a store.Yet many wide- ly-used medicines are from ancient sources,especially plants.Some experts say more than 25% of modern medicines come,in one way or another,from nature.Scientists have long known that nature is really a chemical factory.All living things contain chemicals that help them survive.So scientists' interest in traditional medicine is not new.But it has become an ur-gent concern.This is because the earth's supply of natural medicines may be dropping rapidly. It is believed by scientists that traditional medicines__________.A:can cure all kinds of diseasesB:may cure some of today's most serious diseasesC:are no longer useful for modern menD:are too cheap to be useful

资料:The federal government on Wednesday recommended an endangered-species listing for the loggerhead turtles in U.S. Waters, a decision that could lead to tighter restrictions on fishing and other maritime trades.Environmental groups who’ d been pushing an endangered listing said the proposal was a “turning point”they hope will lead to greater turtle protections.“I think it’ s huge day for loggerhead sea turtles, ”said Beth Riff, a marine wildlife scientist at Oceana.“it really draws attention to the fact these turtles are not doing well and more needs to be done to protect them.”With all that attention to paid to them, you’d think these creatures would at least have the gratitude not to go extinct, but Nature is indifferent to human notions of fairness.No one really knows how many loggerhead there are, or how many are being killed by fishing gear or other activities. Riff cites a 40 percent drop in the number of nesting females in Florida over the last decade as evidence of trouble.Loggerheads are named for their large heads, which contain potent jaws that can crush the hard shells of prey such as conch. The turtles are about the size of a fist when they hatch and make a frenzied dash to the surf. But they typically grow to more than three feet in length and 250 pounds. The animal can log thousands of miles as it travels across oceans.Barbara Schoder,national sea turtle coordinator for NOAA’s fisheries division, said the biggest threats to the North Pacific loggerhead include damage to primary nesting sites, which are mainly in Japan,as well as accidental snaring of the turtles in fishing gear. Andrea Tee of San Francisco-based Center for Biological Diversity said the turtles get hooked by Hawaiian longline fishermen targeting swordfish and tuna and can be injured or drowned. On the East Coast, the main threat to turtles is gear from the region’s various fishenes Schoder said.A primary benefit of the endangered status would be increased public pressure on protecting the species, Riff said. But the government would also have to determine“critical habitats,”such as where the turtles reproduce or forage. Such places could be subject to additional protections for the turtles, including restrictions on maritime development or fishing.Like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems, The narrow strips of beach on which the turtles lay their eggs are being squeezed on one side by development and on the other by threat of rising sea levels as the oceans warm. Ultimately we must get a handle on those issues as well, or a creature that outlived the dinosaurs will meet its end at the hands of humans, leaving our descendants to wonder how creature so ugly could have won so much affection.What does the author mean by “nature is indifferent to human notions of fairness”( ).A.Nature is quite fair regarding the survival of turtlesB.Turtles are by nature indifferent to human activitiesC.Course of nature will not be changed by human interferenceD.The turtle population has decreased in spite of human protection
