But with ___41___ numbers of people wanting to escape into the wilderness, it is becoming more and more important to camp unobtrusively (不引人注目地) and leave no mark.Wild camping is not permitted in many places, ___42___ in crowded lowland Britain. Wherever you are, find out about organizations ___43___ for managing wild spaces, and ___44___ them to find out theirpolicy on camping and shelter building.

A busy, fully-equipped campsite seems to go against this, so ___47___ out smaller, more remote places with easy ___48___ to open spaces and perhaps beaches. Better still, find a campsite with no road access: walking in makes a real adventure.Finding the right spot to camp is the first step to ___49___ a good night’s sleep. Choose a campsite with privacy and minimum influence on others and the environment. Try to use an area where people have ___50___ camped before rather than creating a new spot. Always consider what influence you might have on the natural world. Avoid damaging plants. A good campsite is found, not made—changing it should be unnecessary.III. Reading ComprehensionRecent years have seen considerable growth in the number of children learning a second or foreign language, as the importance of being able to use a language other than one’s first language has become recognized in an increasingly globalized world. In Asia and Europe ___51___, there has been a tendency to ___52___ the age at which school children begin to learn a foreign language, since it is believed that the earlier a child starts to learn a foreign language, the greater the ultimate achievement will be.In many countries, the language of education is not the same as the language of the home for__53__ children. Furthermore, in many countries, young language learners comprise the most rapidly growing segment of the elementary (primary) school population.___54__ in some schools there is no extra support to help young language learners acquire the language of instruction, in most countries where there are large numbers of young learners, there is a ___55___ awareness of their special needs. There is ___56___ a need to identify the needs of young language learners, to ___57___ what level, if any, of proficiency they have in the target language to diagnose their strengths and areas in need of improvement. Language ___58___, whether this is informal, classroom- based, or large-scale, thus has a __59___ role to play in gathering the information needed for these purposes.Unfortunately, the vast majority of teachers who work with young language learners have had little or no ___60___ training or education in language assessment. Teachers are involved in assessment on a daily basis, as they ___61___ their pupils’ classroom performance, and as they develop formal classroom assessments. Assessment should therefore, wherever possible, be familiar and involve familiar adults, rather than ___62_____. The environment should be safe for the learner. Teachers responding___63___ to the child’s efforts is ideal for young learners. Such feedback maintains attention and ___64___. As children grow, they are able to work more ____65___ and for long spans of time without ongoing feedback.51. A. in particular B. as a result C. for example D. in other words52. A. shorten B. enlarge C. lower D. increase53. A. the majority of B. the amount of C. the quantity of D. the number of54. A. Before B. While C. As D. If55.

A. independently B. dependently C. roughly D. carelesslySection B( A )1. ExerciseStudies show that 30 minutes of mild exercise a day will increase your life span. This doesn’t mean you have to run three miles or start jumping. Simple activities such as walking, gardening or taking exercise classes will work.2. Enjoy peopleContacts with family and friends help fight life-sapping depression and stress. Studies show that people socialize regularly live longer than loners. Interact daily with family members and friends. If you are isolated, make a point of joining social clubs or church groups so you can laugh and share life’s joys. 3. Stay mentally activeThis is very important—use it or lose it! People who allow their mental faculties to decline run the risk of shortening their lives through falls and other injuries, and not being able to take care of themselves. Read the newspaper, visit the public library, balance your checkbook without a calculator, and exercise your brain by doing crossword puzzle.4. DietThe key words are “ high-fiber, low-fat”. Cut back on red meat, salt, white flour, white sugar, alcohol and coffee. Start eating a balanced diet including lots of fruit, grains, raw vegetables and nuts.5. Positive attitudeBy approaching life with a positive outlook you increase your chances of living longer. Stay optimistic—always search for the silver lining. Studies show people who see life as an enjoyable challenge, rather than a constant trial, cope better and prolong their life spans.6. medication mixAs we age, we are more likely to take medications. Sometimes this leads to over-medication, which can be disabling and even deadly. Ask your doctor if the drugs you take are really necessary. Make sure there is no danger of a bad drug interaction from your medication. Used correctly, medicines can help you live longer and more comfortably.7. VolunteerHelping others increases your self-esteem and makes you feel like a valuable contributor.66. Which of the following does NOT increase your life span?A. Staying happy about lifeB.

Which of the following is correct about medication ?A. Appropriate medication is necessary.B. Medication is always helpful to you.C. Doctors suggest taking expensive medicines.D. Drugs are unnecessary because of side-effects.( B )“W e are going to have to get rid of Bay this year,” Meg’s dad said. “That horse can’t work another winter.”It was October, and snow was falling lightly over their part of Montana. Meg knew the ranch needed strong, steady horses to bring the sheep back from pasture. Still, she could hardly take in the enormity of her father’s words.“I know Bay’s old,” Meg told her dad, “but he is my horse. Won’t you let me keep him? I’d feed him. He won’t be a problem.”“We use horses for labor,” her dad said, “We don’t keep them as pets.”Meg understood. She thought about Casey, a dog she had once loved. He became lost when he chased a wandering sheep and never came home. Meg had been sad for weeks. She knew that on a ranch, animals come and go. You couldn’t grow attached to them. Bay was different, though. The horse had a personality all his own.She went to the stable and stroked the old brown horse’s head. As Bay nuzzled her hand, Meg tried to imagine what the ranch would be like without her favorite horse.The snow was falling faster, and dark gray clouds were settling over the peaks. Meg had an idea. She saddled Bay, put her foot in the stirrup, and swung up. “Let’s go !” she cried, and nudged him with heels.They galloped over the meadow, onto a steep and narrow trail, and up a wooded slope. “We’ll round up the sheep now, before the snow gets too thick,” Meg said. “We will show Dad how well you work.”.The sheep stood in a high pasture, bleating at the storm clouds. Meg heard a lone bleat from above. She looked for the lost sheep but couldn’t see it. “It must be stuck in the bush above the rock wall,” she thought.She got off her horse and began to climb up the steep wall. She was almost at the top when the heel of her foot slipped into a crack. She lost her balance and fell onto a rock. She tried to stand, but her foot hurt too much.Then Bay got into position under the rock. He was telling Meg to crawl onto his back!Painfully, Meg got her feet into the stirrups. Slowly and carefully, Bay carried her down the snow trail.On the way down, they met Dad riding his gray horse. “What happened ?” he asked anxiously.“Bay saved me.” Meg told him what happened.Dad’s voice shook when he said, “ I wouldn’t get rid of that horse for anything.”70. Meg’s dad intended to ______________.A. trade Bay for sheepB. let Meg keep Bay as a pet.C. sell or kill BayD. keep Bay working for another winter.71. Meg hoped to keep Bay because______________.A. Bay was a good sheep-keeper.B. Bay was like a good friend.C. Bay was strong and beautiful.D. Bay was the only animal she loved.72. Meg rode Bay to the pasture to ___________.A. look for a lost sheep.B. round up the sheep.C. climb over the meadow.D. meet her father.73. Why does Dad change his mind about Bay?A. Bay found the lost sheep and Meg.B. Bay was such a good friend to Meg.C. Bay proved his importance by rescuing Meg.D. Bay proved that he had a personality all his own.( C )One picture in the Wonder Book of knowledge I had as a little boy showed a man reading a book while floating in the Dead Sea. What a miracle! How would it feel to lie back in water so thick with salt that it was impossible to sink?Fed by the Jordan River and smaller streams, the Dead Sea is the lowest point on the earth’s surface, and its water is ten times saltier than the Mediterranean. With evaporation its only outlet, salt and other minerals become super-concentrated.Earlier this year, I drove down the long, steep hill to realize my dream. The shoreline was a broad area of bare salt-mud, but the water edge was far out of sight. Had somebody pulled the Dead Sea’s plug? I wondered. Eli Dior, an Israeli official, explained the problem: “ The Dead Sea is drying up. Every year, the surface drops about one meter, and as the water level falls, shadow areas are left high and dry.”Over the last half-century, the five neighboring countries have collectively diverted nearly all the water flowing into the Dead Sea to meet human and agriculture needs. Result: the Dead Sea is being emptied.With population in the region set to double at least in the next 50 years, there is little hope of restoring the water being diverted for human consumption. No country has a drop to spare for the Dead Sea, wherethey know it will just evaporate. To dream of opening the dams and restoring natural balance is plainly unrealistic.Yet one ambitious high-tech dream may turn out to be not only the salvation of the Dead Sea but also a ticket to peace around its shores. The “ Red-Dead” is a proposed $5 billion project to bring sea water some 240 kilometers by pipeline and canal from the Red Sea to the Dead Sea. The Red-Dead may be the only solution, but even if the project is carried out successfully, the Dead Sea will be 10 to 20 meters lower than now and two thirds of its current size.Whatever the future holds, the Dead Sea’s magical mix of sun, mud, sea and salt will surely survive. Many might complain that the Dead Sea is half empty—but for me the Dead sea will always be half full.74. What’s the passage mainly about ?A. Dead Sea—miracle of the world.B. Save the environment of the Dead Sea.C. Slow shrinking of the Dead Sea.D. Why is the Dead Sea so salty.75. The shrinking of the Dead Sea is mainly caused by _________ according to the passage.A. a severe reduction of the water flowing into the sea.B. rapid evaporation of the water in the Dead Sea area.C. the increasing quantity of water drawn from the sea.D. very low annual rainfall in the Dead Sea Area.76. Which of the following is right according to the passage?A. With no outlet to any ocean, the Dead Sea has become by evaporation the saltiest on earth.B. Though burdened with the growing population, the neighboring countries haven’t cut off thesources of the Dead Sea.C. All the countries in the area will consider diverting less water from the Jordan River.D. The Red-Dead Project has not only brought water to the Dead Sea, but peace to the area as well.77. Which of the following statements will the author approve of ?A. If the Dead Sea dried up, great natural disasters would happen in the region.B. The Dead Sea will not survive no matter what people do to save it.C. The five neighboring countries should stop diverting water from the Jordan River.D. Though the Dead Sea is shrinking gradually, it will not die.Section CHowever important we may regard school life to be, there is no denying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of the school personnel or they can consciously or unconsciously hinder and frustrate curricular objectives.Administrators have been aware of the need to keep parents informed of the newer methods used in schools. Many principles have conducted workshops explaining such matters as the reading readiness program, manuscript writing and developmental mathematics. Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea andthe many interviews carried on during the year, as well as new ways of reporting pupils’progress, can significantly aid in achieving a harmonious interplay between school and home.To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate (升华) his natural paternal interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a standard or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and at the same time, enjoying the work. Too often, however, teachers’conferences with parents are devoted to petty (不重要的) accounts of children’s misdeeds, complaints about laziness and poor work habits, and suggestion for penalties and rewards at home.What is needed is a more creative approach in which the teacher, as a professional adviser, plants ideas in parents’ minds for the best utilization of the many hours that the child spends out of the classroom.In this way, the school and the home join forces in fostering the fullest development of youngsters’capacities.(Note: Answer the questions or complete the statements with NO MORE THAN 14 WORDS)78. Why do parents also have great influence on children?_____________________________________________________________________________79. Through which ways can the teacher play an important role in enlightening parents?_____________________________________________________________________________80. According to the teacher, that parent should let the boy _____________________________ if he wants to sublimate his natural paternal interest into productive channels in teaching his son arithmetic.81. A more creative approach is needed for _____________________of children out of classroom.第Ⅱ卷 (共47分)I.

This doesn’t mean you have to run three miles or start jumping. Simple activities such as walking, gardening or taking exercise classes will work.2. Enjoy peopleContacts with family and friends help fight life-sapping depression and stress. Studies show that people socialize regularly live longer than loners. Interact daily with family members and friends. If you are isolated, make a point of joining social clubs or church groups so you can laugh and share life’s joys.3. Stay mentally activeThis is very important—use it or lose it! People who allow their mental faculties to decline run the risk of shortening their lives through falls and other injuries, and not being able to take care of themselves. Read the newspaper, visit the public library, balance your checkbook withouta calculator, and exercise your brain by doing crossword puzzle.4. DietThe key words are “ high-fiber, low-fat”. Cut back on red meat, salt, white flour, white sugar, alcohol and coffee. Start eating a balanced diet including lots of fruit, grains, raw vegetables and nuts.5. Positive attitudeBy approaching life with a positive outlook you increase your chances of living longer. Stay optimistic—always search for the silver lining. Studies show people who see life as an enjoyable challenge, rather than a constant trial, cope better and prolong their life spans.6. medication mixAs we age, we are more likely to take medications. Sometimes this leads to over-medication, which can be disabling and even deadly. Ask your doctor if the drugs you take are really necessary. Make sure there is no danger of a bad drug interaction from your medication. Used correctly, medicines can help you live longer and more comfortably.7.

Drugs are unnecessary because of side-effects.( B )“W e are going to have to get rid of Bay this year,” Meg’s dad said. “That horse can’t work another winter.”It was October, and snow was falling lightly over their part of Montana. Meg knew the ranch needed strong, steady horses to bring the sheep back from pasture. Still, she could hardly take in the enormity of her father’s words.“I know Bay’s old,” Meg told her dad, “but he is my horse. Won’t you let me keep him? I’d feed him. He won’t be a problem.”“We use horses for labor,” her dad said, “We don’t keep them as pets.”Meg understood. She thought about Casey, a dog she had once loved. He became lost when he chased a wandering sheep and never came home. Meg had been sad for weeks. She knew that on a ranch, animals come and go. You couldn’t grow attached to them. Bay was different, though. The horse had a personality all his own.She went to the stable and stroked the old brown horse’s head. As Bay nuzzled her hand, Meg tried to imagine what the ranch would be like without her favorite horse.The snow was falling faster, and dark gray clouds were settling over the peaks. Meg had an idea. She saddled Bay, put her foot in the stirrup, and swung up. “Let’s go !”she cried, and nudged him with heels.They galloped over the meadow, onto a steep and narrow trail, and up a wooded slope. “We’ll round up the sheep now, before the snow gets too thick,” Meg said. “We will show Dad how well you work.”.The sheep stood in a high pasture, bleating at the storm clouds. Meg heard a lone bleat from above. She looked for the lost sheep but couldn’t see it. “It must be stuck in the bush above the rock wall,” she thought.She got off her horse and began to climb up the steep wall. She was almost at the top when the heel of her foot slipped into a crack. She lost her balance and fell onto a rock. She tried to stand, but her foot hurt too much.Then Bay got into position under the rock. He was telling Meg to crawl onto his back!Painfully, Meg got her feet into the stirrups. Slowly and carefully, Bay carried her down the snow trail.On the way down, they met Dad riding his gray horse. “What happened ?”he asked anxiously.“Bay saved me.” Meg told him what happened.Dad’s voice shook when he said, “ I wouldn’t get rid of that horse for anything.”70. Meg’s dad intended to ______________.A. trade Bay for sheepB. let Meg keep Bay as a pet.C. sell or kill BayD. keep Bay working for another winter.71. Meg hoped to keep Bay because______________.A. Bay was a good sheep-keeper.B. Bay was like a good friend.C. Bay was strong and beautiful.D. Bay was the only animal she loved.72. Meg rode Bay to the pasture to ___________.A. look for a lost sheep.B. round up the sheep.C. climb over the meadow.D. meet her father.73. Why does Dad change his mind about Bay?A. Bay found the lost sheep and Meg.B. Bay was such a good friend to Meg.C. Bay proved his importance by rescuing Meg.D. Bay proved that he had a personality all his own.( C )One picture in the Wonder Book of knowledge I had as a little boy showed a man reading a book while floating in the Dead Sea. What a miracle! How would it feel to lie back in water so thick with salt that it was impossible to sink?Fed by the Jordan River and smaller streams, the Dead Sea is the lowest point on the earth’s surface, and its water is ten times saltier than the Mediterranean. With evaporation its only outlet, salt and other minerals become super-concentrated.Earlier this year, I drove down the long, steep hill to realize my dream. The shoreline was a broad area of bare salt-mud, but the water edge was far out of sight. Had somebody pulled the Dead Sea’s plug? I wondered. Eli Dior, an Israeli official, explained the problem: “ The Dead Sea is drying up. Every year, the surface drops about one meter, and as the water level falls, shadow areas are left high and dry.”Over the last half-century, the five neighboring countries have collectively diverted nearly all the water flowing into the Dead Sea to meet human and agriculture needs. Result: the Dead Sea is being emptied.With population in the region set to double at least in the next 50 years, there is little hope of restoring the water being diverted for human consumption. No country has a drop to spare for the Dead Sea, where they know it will just evaporate. To dream of opening the dams and restoring natural balance is plainly unrealistic.Yet one ambitious high-tech dream may turn out to be not only the salvation of the Dead Sea but also a ticket to peace around its shores. The “ Red-Dead” is a proposed $5 billion project to bring sea water some 240 kilometers by pipeline and canal from the Red Sea to the Dead Sea. The Red-Dead may be the only solution, but even if the project is carried out successfully, the Dead Sea will be 10 to 20 meters lower than now and two thirds of its current size.Whatever the future holds, the Dead Sea’s magical mix of sun, mud, sea and salt will surely survive. Many might complain that the Dead Sea is half empty—but for me the Dead sea will always be half full.74. What’s the passage mainly about ?A. Dead Sea—miracle of the world.B. Save the environment of the Dead Sea.C. Slow shrinking of the Dead Sea.D. Why is the Dead Sea so salty.75. The shrinking of the Dead Sea is mainly caused by _________ according to the passage.A. a severe reduction of the water flowing into the sea.B. rapid evaporation of the water in the Dead Sea area.C. the increasing quantity of water drawn from the sea.D. very low annual rainfall in the Dead Sea Area.76. Which of the following is right according to the passage?A. With no outlet to any ocean, the Dead Sea has become by evaporation the saltiest on earth.B. Though burdened with the growing population, the neighboring countries haven’t cut offthe sources of the Dead Sea.C. All the countries in the area will consider diverting less water from the Jordan River.D. The Red-Dead Project has not only brought water to the Dead Sea, but peace to the area aswell.77. Which of the following statements will the author approve of ?A. If the Dead Sea dried up, great natural disasters would happen in the region.B. The Dead Sea will not survive no matter what people do to save it.C. The five neighboring countries should stop diverting water from the Jordan River.D. Though the Dead Sea is shrinking gradually, it will not die.Section CDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.However important we may regard school life to be, there is no denying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of the school personnel or they can consciously or unconsciously hinder and frustrate curricular objectives.Administrators have been aware of the need to keep parents informed of the newer methods used in schools. Many principles have conducted workshops explaining such matters as the reading readiness program, manuscript writing and developmental mathematics. Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils’progress, can significantly aid in achieving a harmonious interplay between school and home.To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate (升华) his natural paternal interest into productive channels. He might be persuaded to let Junior participate in discussing the family budget, buying the food, using a standard or measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in mathematics, and at the same time, enjoying the work. Too often, however, teachers’conferences with parents are devoted to petty(不重要的) accounts of children’s misdeeds, complaints about laziness and poor work habits, and suggestion for penalties and rewards at home.What is needed is a more creative approach in which the teacher, as a professional adviser, plants ideas in parents’ minds for the best utilization of the many hours that the child spends out ofthe classroom.In this way, the school and the home join forces in fostering the fullest development of youngsters’capacities.(Note: Answer the questions or complete the statements with NO MORE THAN 14 WORDS)78. Why do parents also have great influence on children?_____________________________________________________________________________79. Through which ways can the teacher play an important role in enlightening parents?_____________________________________________________________________________80. According to the teacher, that parent should let the boy _____________________________ ifhe wants to sublimate his natural paternal interest into productive channels in teaching his sonarithmetic.81. A more creative approach is needed for _____________________of children out of classroom.第Ⅱ卷(共47分)I.
