Recent studies of 36 rate have had conflicting results.For one thing, schools define and measure their dropout rates 37 . Some researchers say about 15 to 20 percent of public school students do not 38 their education on time. 39 many other experts and policymakers believe that for the past 20 years, the dropout rate has been around 30 percent. For Latino and black students, the 40 are even larger. Researchers say almost half of them 41 school. At the same time, almost half of the states let students leave school 42 the age of 18 without informing their parents.Finding a good job 43 a high school education is becoming more and more difficult. A Northeastern University 44 in 2002 found that almost half of all dropouts aged 16 to 24 did nothave a job. The 45 of a high school education can also 46 other problems. It is estimated that two-thirds of prisoners in the United States dropped out of high school.Recent studies have 47 that the majority of students who drop out do it because they are failing. Many are 48 with their classes or feel disconnected from their school and teachers. Some students feel that educators place low 49 on them.During the past 20 years, there have been efforts to 50 graduation rate through education reforms. Some communities are working on dropout 51 programs. These include some alternative high schools to meet special 52 .Experts think “early warning systems” can help 53 young schoolchildren at the risk of dropping out of high school.

Now more and more women are taking the front seat. More than twenty million people in the United States ride motorcycles.Since 1998 the number of female bikers has risen sharply. Lady Sport Riders began in 1999 in Washington. The women formed the organization to share their love of motorcycle riding. But later it wanted to be more than just an organization for women to gather and ride motorcycles, so it started to organize events that help national health organizations and women’s shelters. It also permits women to share a strong sisterhood, and gives financial awards to poor students. Like other motorcycle clubs, the members of Lady Sport Riders also help their community.Different from male riders, female riders ride for more than fun. This sport gives women a sense of freedom and control. Female riders have helped change motorcycle culture. More than five years ago manufacturers began making equipment especially for women. Some bikes now have smaller, softer seats and controls that are easier to reach. Modern clothes for riding now look good and still provide protection. In the past, women rode motorcycles that traveled at a moderate speed. Now theirs are as powerful as the ones men ride. Safety is very important when riding because the risk of injury is high. So the women wear protective clothing and equipment at all times, especially for the head.Lady Sport Riders believes women have earned their place in the sport of motorcycle riding. When speaking of male motorcyclists, the members of the club say, “They Made the Game. We Came to Play!”56. What can we learn from the first paragraph?A. Motorcycle riding used to be considered a male sport.B. The number of female motorcyclists is now larger than that of male riders.C. Female motorcyclists are more skilled at riding than male riders.D. More and more women have an adventurous spirit.57. In the beginning, Lady Sport Riders was organized to .A. allow women to take up motorcyclingB. offer help to national health organizationsC. share their great interest in the sport of motorcyclingD. supply financial help to poor students58. What do men motorcyclists mainly expect to get from motorcycling?A. Strength and power.B. A sense of freedom.C. Money and fame.D. Pleasure from this sport.59. Compared with the past, the present equipment makes riding more ______ for women.A. difficultB. pleasantC. riskyD. expensive60. What is the purpose of the passage?A. To talk about the development of motorcycle riding.B. To talk about the characteristics of the sport of motorcycling.C. To introduce a female motorcycle club to readers.D. To talk about the role women have played in the sport of motorcycling.BAbout 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink seawater, how can it be important?Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important seawater is!Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishingrestrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important seawater is!61. Which of the following is the proper order of the food chain?A. small animals→algae→microscopic animals→large animals→manB. algae→microscopic animals→large animals→larger animals→manC. small animals→algae→large animals→microscopic animals→manD. microscopic animals→algae→large animals →larger animals→man62. People used to think that the rubbish thrown into the sea ________.A. wouldn’t harm the fish in the seaB. would change the balance of the food chainC. would be broken down in the seaD. wouldn’t do much harm to the sea63. From the passage, we learn that _________.A. most fish and sea animals live at the surface of the seasB. it is very difficult to break the balance of a food chainC. excessive fishing has caused the decrease in fish stockD. it won’t be long before the problems concerning oceans will be solved64. Which of the following is NOT a way being used to protect oceans?A. The use of international agreements.B. Forbidding fishing to protect fish stocks.C. The use of new techniques.D. Raising people’s awareness of the need to protect oceans.65. What would be the best title of the passage?A. The importance of seawater.B. Life in the oceans.C. How to protect food chains.D. How to deal with seawater pollution.CHomes & Gardens12mths: £27.04Established for over 80 years, Homes & Gardens has always been engaging and accessible.

As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease.In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines. Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need.71. What is probably talked about before this passage?A. How many vitamins a person’s body needs.B. How many vitamins some foods contain.C. The benefits that vitamins bring to our health.D. What people should do to stay healthy.72. Vitamin supplements are popular with people because ________.A. people mistakenly think that they are good for their healthB. they contain more vitamins than the foods people eatC. food does not provide enough vitamins people needD. people fear that a lack of vitamins will lead to disease73. From the passage, we can learn that medical experts advise people _________.A. never to take any vitamin supplementsB. to depend only on food for their vitaminsC. not to take any vitamins together with medicinesD. to consult doctors before taking vitamin supplements74. For people who lack Vitamin B-twelve, they can eat more from _______.A. sweet potatoesB. pork productsC. green leafy vegetablesD. eggs75. What would be the best title of the passage?A. Getting enough vitamins through a balanced diet.B. Vitamin supplements do harm to our health.C. Vitamins are important to our health.D. Lacking vitamins can cause many diseases.第四部分写作（共两节，满分45分）第一节阅读表达（共5小题；每小题3分，满分15分）阅读下面的短文，并根据文章后的题目要求回答76-80小题。

Boxes can usually serve as new storage containers and houses for pets.And clothing? Imagine taking old clothes and turning them into hats or bags.【解题导语】本文主要讲述了一位德国艺术家利用垃圾创造艺术作品的故事，并以此鼓励读者行动起来，为环保出一分力。

percent of the world’s 400 species are harmless to humans.A shark exhibition at the National Aquarium Baltimore,the US,proves this.Visitors can touch young sharks,see their eggs develop and watch a dozen different species swim smoothly around a huge tank.Most people fail to realize that shark attacks don’t happen very often.Humans are most likely to be killed by lightning than by a shark.And to make this point clear,the museum has set up a special touching pool for children.There,kids can learn,from an early age,not to fear sharks.They can watch them develop inside their eggs and feel the skin of the older swimmers.“People fear what they don’t know,”said Nancy Hotchkiss,an organizer of the exhibition,which runs until D ecember.“Sharks have been around for 400 million years and play an important role in the ocean’s food chain.We want people to discover that sharks are amazing animals that need our respect and protection.”A shocking 100 million sharks are special foods killed around the world by humans.A study published in January in theUSmagazine Science found that almost all recorded shark species have fallen by half in the past 8 to 15 years.Thousands of sharks are hunted in Asia for special foods,such as shark fin(鱼翅)soup.And many others get caught in nets,while fishermen are hunting other fish.More than half of all sharks are smaller than one metre long.“Some fishing methods are actually cleaning out the ocean,”said Dave Schofield,the manager of the aquar ium’s museum.“The fishermen throw them away like rubbish.”It is a worrying situation and some areas have taken measures in place to protect these special fish.1.The main purpose of the shark exhibition is to __________________.A.show how sharks are born and develop in the oceanB.let people know more about sharks and protect themC.let children learn not to fear sharks from an early ageD.show how shark species have fallen in the past few years2.In the last but one paragraph,the underlined word“them”refers to _____________.A.small sharksB.fishing boatsC.fishing netsD.fishing methods3.What does Dave Schofield mean by saying “Some fishing methods are actually cleaning out the ocean”?rge sharks cannot be caught by some fishing methods.B.Only small sharks can be caught by some fishing methods.C.The ocean is being made cleaner by some fishing methods.D.Too many sharks are being killed by some fishing methods.4.It can be inferred from the article that ____________________.A.the writer is surprised to know sharks always hurt peopleB.the writer is happy to know sharks are harmless to peopleC.the writer is worried about the present situation of shark speciesD.the writer is pleased to know the ocean is becoming much cleaner5、 What do you know about the sea?We know that it looks very pretty when the sun is shining on it.We also know that it can be very rough when there is a strong wind.What other things do we know about it?The first thing to remember is that the sea is very big.When you look at the map of the world you will find there is more water than land.The sea covers three quarters of the world.The sea is also very deep in some places.It is not deep everywhere.Some parts of the sea are very shallow.But in some places the depth of the sea is very great.There is one spot,near Japan,where the sea is nearly 11 kilometres deep!The highest mountain in the world is about 9 kilometres high.If that mountain were put into the sea at that place,there would be 2 kilometres of water above it!What a deep place!If you have swum in the sea,you know that it is salty.You can taste the salt.Rivers,which flow into the sea,carry salt from the land into the sea.Some partsof the sea are saltier than other parts.There is one sea,called the Dead Sea,which is very salty.It is so salty that swimmers cannot sink!Fish cannot live in the Dead Sea!In most parts of the sea,there are plenty of fishes and plants.Some live near the top of the sea.Others live deep down.There are also millions of tiny living things that float in the sea.These floating things are so small that it is hard to see them.Many fish live by eating these.The sea can be very cold.Divers who go deep down in the sea know this.On the top the water may be warm.When the diver goes downwards,the sea becomes colder and colder.Another thing happens.When the diver goes deeper,the water above presses down on him.It squeezes him.Then the diver has to wear clothes made of metal.But he cannot go very deep.Some people who wanted to go very deep used a very strong diving ship!They went down to the deepest part of the sea in it.They went down to a depth of eleven kilometres!1.When does the sea look beautiful?A.When it is calm.B.When the weather is fine.C.When there is a strong wind.D.When there is storm.2.Why does the author cite(引用)the sea somewhere in Japan?A.To show that the sea in some places is very deep.B.To show that the sea in some places is very rough.C.To show that its depth is 9 kilometres greater than the height of the highest mountain.D.To show that its depth is 11 kilometres greater than the height of the highest mountain.3.Which of the following statements about the Dead Sea is NOT true?A.There are plenty of fishes in it.B.It is a safe place for swimmers.C.It is extremely salty.D.No fish can be found in it.4.Why can’t people go very deep in the sea?A.Because the deepest part of the sea is very cold.B.Because the deepest part of the sea is very rough.C.Because the pressure of water at great depths is unendurable(无法忍受的).D.Because the deepest part of the sea is very salty.6、 If a diver surfaces too quickly, he may suffer the bends. Nitrogen(氮) dissolved(溶解) in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles(气泡) accumulate in a joint, is sharp pain and a bent body—thus the name. If the bubbles from in his lungs or his brain, the consequence can be death.Other air-breathing animals also suffer this decompression(减压) sickness if they surface too fast:whales, for example. And so, long ago, did ichthyosaurs. That these ancient sea animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil(化石) bones that have caved in on themselves are thus a sign that the animal once had the bends.Bruce Rothschild of the University of Kansas knew all this when he began a study of ichthyosaur bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompression over the 150 million years. To this end, he and his colleagues traveled the world’s natural-history museums, looking at hundreds of ichthyosaurs from the Triassic period and from the later Jurassic and Cretaceous periods.When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic andCretaceous ichthyosaurs had suffered the bends before they died, but not a single Triassic specimen(标本) showed evidence of that sort of injury.If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly—and, most strangely, they lost it afterwards. But that is not what Dr Rothschild thinks happened He suspects it was evolution in other animals that caused the change.Whales that suffer the bends often do so because they have surfaced to escape a predator(捕食动物) such as a large shark. One of the features of Jurassic oceans was an abundance of large sharks and crocodiles, both of which were fond of ichthyosaur lunches. Triassic oceans, by contrast, were mercifully shark-and crocodile-free. In the Triassic, then, ichthyosaurs were top of the food chain. In the Jurassic and Cretaceous, they were prey(猎物) as well as predator—and often had to make a speedy exit as a result.1.Which of the following is a typical symptom of the bends?A.A twisted body.B.A gradual decrease in blood supply.C.A sudden release of nitrogen in blood.D.A drop in blood pressure.2.The purpose of Rothschild s study is tosee .A.how often ichthyosaurs caught the bendsB.how ichthyosaurs adapted to decompressionC.why ichthyosaurs bent their bodiesD.when ichthyosaurs broke their bones3.Rothschilds finding stated in Paragraph4 .A.confirmed his assumptionB.speeded up his research processC.disagreed with his assumptionD.changed his research objectives4.Rothschild might have concluded thatichthyosaurs .A.failed to evolve an anti-decompression meansB.gradually developed measures against the bendsC.died out because of large sharks and crocodilesD.evolved an anti-decompression means but soon lost it7、下面短文中有10处语言错误。

AScientists today are making greater effort to study ocean currents(洋流）. Most do it using satellites and other high－tech equipment. However， ocean expert Curtis Ebbesmeyer does it in a special way—by studying movements of random floating garbage.A scientist with many years’experience， he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States。
There were so many shoes that people were setting up swap_meets to try and match left and right shoes to sell or wear.Ebbesmeyer found out in his researches that the shoes—about 60，000 in total-fell into the ocean in a shipping accident。
He phoned the shoe company and asked if they wanted the shoes back。
