阅读理解——说明文（江苏省盐城市景山中学2013年3月调研，四C）In recent years advances in medical technology have made it possible for people to live longer than in the past.New medicines and instruments are being developed every day to extend （延长）life.However，some people，including some doctors，are not in favour of these life extending measures，and they argue that people should have the right to die when they want.They say that the quality of life is as important as life itself，and that people should not be forced to go on living when conditions of life have become unbearable（不能忍受的.They say that people should be allowed to die with dignity（尊严）and to decide when they want to die.Others argue that life under any conditions is better．57.In recent years, people can live longer than in the past,It‘s because of_________.A.the development of medical technologyB.big hospitalsC.good doctorsD.both B and C58.According to some people，whether a dying patient has the right to die or not is upto_________.A.the doctorsB.the surroundings（环境）C.his or her familyD.the patient himself or herself59.The writer‘s opinion is_________.A.death is better than lifeB.life is better than deathC.neither death nor life is goodD.none of the above60.Why do some patients want to die? Because_______.A.the doctors are not goodB.the conditions are badC.life is too hardD.they are seriouly ill【答案】ADDD（江苏省盐城市景山中学2013年3月调研，四D）Have you ever wondered?1. Why do airplanes take longer to fly west than east?It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet (喷射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction.2. What would happen if the gravity on Earth was suddenly turned off?Supposing we could magically turn off gravity. Would buildings and other structures (建筑物) float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turnsomething around your head on a string (细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly shoot upwards at a great speed until they hit the ceiling. Most things outside would fly off into space.61. What information can we get from the first passage?A. It is the jet stream that affects how fast airplanes fly.B. Planes go slower when they are moving with the wind.C. It takes more time to fly from NY to London than from London to NY.D. The jet stream always blows from the east to the west across the Atlantic.62.The word ―shoot‖ underlined in the 2nd passage probably means ―__________‖.A.send forB. move quicklyC. come outD. grow quickly63. It can be inferred that without gravity __________.A. buildings and other structures would float awayB. trees and buildings would not so easily fly offC. something around your head would not float awayD. everything outside buildings would fly off into space64.Which of the following statements is not mentioned in the passage?A.It takes seven hours to travel from London to New York.B.The earth is moving at a high speedC.Everything on the earth will float away if there‘s no gravity.D.Everything not attached to the earth would fly off in a straight line.65. Where can we most probably read this text?A. In a research paper.B. In a short story.C. In a travel magazine.D. In a student‘s book.【答案】ABBCA（浙江省永嘉县2013届第一次适应性考试，四C）Today most countries have at least one airline that flies to foreign countries and one airline that flies inside the country. Some countries have several of each.The world's first passenger airline was called the St. Petersburg Tampa Airboat Line. This St. Petersburg was in Florida in the USA, and the airline took passengers on a 20-mile flight across Tampa Bay. It operated for only four months from January 1914.The first European airline flew every day from Berlin to Weimar. Called Deutsche Lutt-Reederei (DLR), it started to operate on 6 February 1919. At first it carried only mail and newspapers, but before long it took passengers as well. The planes were open to the air so passengers had to wear special clothing and shoes to protect them from the wind, rain and cold.In March 1919 the first international airline began to operate. Lignes Aeriennes Farman flew once a week between Paris and Brussels. The journey took two hours and 50 minutes. Later that year, an English airline, Air Transport and Travel, flew every day from London to Paris.Although the first passenger flights took place in the USA, the development of air travel in America was strangely slow; it was not until 1926 that there were any regular passenger services there. It was not until 1939 that the first service across the North Atlantic began to operate. This was a service by the Pan American Boeing 314 flying boat, Yankee Clipper, which took 18 hoursand 42 minutes to cover the journey between Newfoundland in North America and Southampton in England. The journey now takes about four hours by Boeing 777 and half that by Concorde.Today for many people air travel is as much part of their lives as traveling by boat, car or train. Although it has not seriously affected travel by car or train, it has caused many shipping lines to stop carrying passengers, as most people now prefer to make long journeys by air rather than by sea.48. The first passenger airline ___________.A. traveled across land to TampaB. operated in RussiaC. operated only for a short timeD. started in a famous city49. DLR carried ___________.A. mail and newspapers onlyB. passengers onlyC. shoes and clothingD. mail at first, then passengers later50. The flight across the Atlantic by Concorde takes ____________.A. two hoursB. two hours and 50 minutesC. four hoursD. 18 hours and 42 minutes51. The story is about __________.A. the history of flight B the development of passenger air travelC. the invention of the first planeD. the development of the first airline【答案】48-51 CDAB（江苏省盐城市景山中学2013年3月调研，四A）A sign is another kind of language. Here are some of them that you see on the roads.Number One is a sign with the number thirty on it. Whendrivers see this sign, they must not go at more than thirty kilometers an hour. We see this sign when we are getting near a town. Number Two is a sign that we‘re near a crossing. We must drive careful ly. Number Three is a sign that there is a bend (拐弯) in the road. Again, we must drive slowly and carefully. It is not safe to go around a bend very fast. Number Four is a sign that there is another road coming in from the right. There is a junction (交叉) at this place. Number Five is a sign that there is a hill and Number Six is a sign that the road gets narrow. Drivers must go slowly and carefully. Number Seven has the word ―SCHOOL‖ on it. This is a sign that there is a school at the side of the street or the road. Perhaps there are children going to or leaving school. So drivers must look carefully and go slowly. Number Eight is a sign with the letter ―P‖ on it. The letter ―P‖ means ―Parking‖. At some places, there are the signs ―No parking‖ or ―No waiting”. If a driver leaves his car near one of these signs, a policeman may come and write down the number of his car.51. At the places where you see Sign 1, ____________..A. you are already out of a townB. you still have thirty kilometers to goC. there must be many houses and building not far awayD. there must be a town thirty kilometers away52.

But that‘s not true. There are many interesting stories in the paper. You just need to make clear what you are looking at. ―I spend about half an hour reading newspapers every day,‖ said 15-year-old Gao Ming from Beijing. ―I‘m interested in things happening at school.‖ School news is just one kind of news story in newspapers. There‘s also world news: from international problems to pop stars.Read the newspaper carefully, we‘ll find different types of articles on the pages:News stories — these stories are about events. Reporters try to show all points of a story to help readers understand what happened. Reporters try to speak to as many people as possible. They also use pictures and numbers to show the readers that the stories are true. The newspaper Teenagers has lots of news stories on the news page and front page. When we read them, we learn more about the facts, not the writers‘ ideas.Opinion writing — opinion writing is usually about something happening right now. But it isn‘t just facts. Here writers add their own opinions to the news. Writers pick only the facts that help back up their ideas. They make readers believe that they are telling the truth. This is usually the kind of story that gets people thinking. Go to ―Speak Out‖ on Page Two for an example of opinion writing in Teenagers.Advertisement —Don‘t get happy too early when you read them. Those sweet words and lovely pictures are just ways to get us interested in their products! People have to pay to put advertisements in newspapers!54.

Some prepare students for workers, others prepare them for college. All schools are great places for making friends and learning German. Short daysMost high schools in Germany begin at about 8:00 a.m. and end at about 3:30 p.m. This means your morning will be busy with classes. You will have time to do homework and take part in private(私人的) clubs after school.Formal settingIn Germany, teachers and students‘ relationship is more formal than you might be used to. Teachers are respected and students must use the formal ―Sie（德语，您）‖ when talking to teachers.Getting to schoolMost students take public transport to school or ride a bicycle. Some areas have school buses. It is not common for parents to drive students to school.Private clubsIn many countries, schools offer official sports and after-school activities. This is less common in Germany. After-school activities are usually organized through private clubs. There are clubs for things like soccer, dance, choir, theatre and almost everything else.

In this article, you‘ll learn how acid is created, and how it affects us, and more importantly, what we all can do to prevent it.How is acid rain created?When people use fuels(燃料), such as coal and gasoline, poisonous gases are given off. When these gases mix with rain, acid rain forms. Many power stations burn fuels in order to create the electricity(电) that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they burn gasoline .When rain mixes with these gases, harmful things called acids form. This is acid rain.How does acid rain affect us?Acid rain damages(毁坏)everything that it touches. It poisons our rivers, ponds, lakes, and oceans along with all the life in them. It pollutes our soil and crops, harms trees, and can even kill fish and plants. Acid rain also eats away at buildings.How can we prevent acid rain?We need to cut down on the pollution that gets into our air. Turn off lights, television, and other electrical appliances if you are not using them, Walk or take a bike whenever possible. If you are travelling a long distance, take a bus or train to save fuel.As research shows, acid rain harms our environment. But people everywhere can take small steps now to help protect our environment for future generations.28.

D（江苏省无锡市育才中学2013年一模D）After spending years searching for a planet with life, scientists mayhave found one. In September 2010, a team of US scientists discoveredan Earth-sized planet called Gliese 581g. It has a surface temperatureneither too hot nor too cold for liquid（液态）water. Scientists think thereis a chance that the planet could have life.The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can‘t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don‘t come anywhere near that one-tenth light-speed mark.At present, scientists don‘t know what the surface might be like on Gliese 581g. What they know is that the planet is at the r ight distance from its star to have liquid water. It‘s also at the right distance to have an atmosphere that could protect the water if it is on the surface.Although spacecraft won‘t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover if Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea whether the planet has life or not. But it‘ll probably be many years before we can do this properly.People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.34. What did scientists find in September 2010?A. A planet with water.B. A planet similar to the earth.C. A planet without life.D. A planet near the earth.35. According to the article, Gliese 581g ________.A. is at the right distance from its starB. moves around the earthC. is as far away from us as the moonD. can be reached in about 220 years36. Paragraph 5 is mainly about ______.A. the possibility of living on Gliese 581gB. the kinds of chemicals around Gliese 581gC. the way of looking for life on Gliese 581gD. the aim of studying the radiation on Gliese 581g37. Which of the following is the best title for the passage above?A. Gliese 581g, a Likely Living PlanetB. Gliese 581, a Likely Living PlanetC. Gliese 581g and Its StarD. Gliese 581g and Radiation【答案】34. A 35. A 36. C 37. A（江苏省无锡市惠山区2013年九年级期中）C―Sesame Street‖has been called ―the longest street in the world‖. That is because the television program by that name can now be seen in many parts of the world. That program became one of American exports soon after it went on the air in New York in 1969.In the United States more than six million children watch the program regularly. The viewers include more than half the country‘s pre-school children, from every kind of economic, racial (种族的), and geographical group.Although some educators object (反对) to some parts of the program, parents praise (赞扬) it highly. Many teachers also consider it a great help, though some teachers find that problems come out when first graders who have learnt from ―Sesame Street‖ are in the same class with childrenwho have not watched the program.Tests have shown that children from all racial, geographical, and economic backgrounds have benefited (受益) from watching it. Those who watch it five times a week learn more than occasional (偶尔的) viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.The programs all use songs, stories, jokes and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate (单独的) letters.Why has ―Sesame Street‖ been so much more successful than other children‘s shows? Many reasons have been suggested. People mention the educational theories (理论) of its creators, the support by the government and private businesses, and the skillful use of various TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching it feel able to learn. The child finds himself learning, and he wants to learn more.31. Which of the following statements is NOT true?A. It is shown at different hours during the week.B. Famous adult stars often appear on it.C. This program has been on for less than forty years.D. Children learn and enjoy themselves while watching it.32. Why is ―Sesame Street‖ so popular in the world?A. Because it is supported by the government and businesses.B. Because it uses different kinds of skillful tricks.C. Because mothers watch it along with their children.D. Because it makes every child watching it feel able to learn.33. The best title for this passage can be _________.A. Sesame StreetB. Educating ChildrenC. TV ProgramsD. A Great Success【答案】31 --- 33CDA（江苏省无锡市惠山区2013年九年级期中D）The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image of unhappy teenagers locked in their room after endless family quarrels.An important new study into teenage attitudes (态度) surprisingly shows that their family life is happier than it has ever been in the past. ―We were surprised by just how positive (积极的) today‘s young people seem to be about their families,‖ said one member of the research team. ―They‘re expected to be rebellious（叛逆的）and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There‘s discussion between parents and children, and children expect to take part in the family decision-making process. They don‘t want to rock the boat.‖So it seems that these parents are much more likely than parents of 30 years ago to treat their children as friends. ―My parents are happy to discuss things with me and willing to listen to me,‖says 17-year-old Daniel LaSalle. ―I always tell them when I‘m going out clubbing. When they know what I‘m doing, they‘re fine with it.‖ Susan Cromer, who is now 21, agrees. ―Looking back on the last 10 years, there was a lot of what you could call talk or discussion. For example, when I‘d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot strict er with my parents than that.‖Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion（叛逆）is not based on real facts. A researcher explain s, ―Teenagers were thought to be different from others in a part of time in our social history. But to our surprise, they say they are getting on well with their parents. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled.‖34. The study shows that teenagers don‘t want to ______________________.A. share family dutiesB. cause trouble in their familiesC. go boating with their familyD. make family decisions35. Compared with parents of 30 years ago, today‘s parents ___________________.A. go to clubs more often with their childrenB. are much stricter with their childrenC. care less about their children‘s lifeD. give their children more freedom36. According to the writer, teenage rebellion ____________________.A. may be a wrong opinionB. is common at presentC. lived only in the 1960sD. was caused by changes in families37. Which title best gives the main idea of the passage?A. Discussion in family.B. Teenage education in family.C. Harmony in family.D. Teenage trouble in family.【答案】34 --- 37 BDAC（江苏省南京市江宁区2013届九年级中考一模,D）Animals do many different, amazing things to get throughthe winter. Some of them migrate. They travel to other placeswhere the weather is warmer or where they can find food.Many birds migrate in autumn. Because the trip can bedangerous, some travel in large groups. For example, geese(鹅)fly in noisy, ―V‖-shaped groups. Other kinds of birds fly alone.Some animals stay active in winter. They must change themselves as the weather changes. Many change their doing or their bodies. For example, snowshoe rabbits grow white fur to help them hide in the snow.Food is hard to find in winter. Some animals, like mice, collect lots of food in autumn and store it to eat later. Some animals eat different kinds of food as the seasons change.Some animals hibernate for part or all of the winter. This is a special, very deep sleep. The animal‘s body temperature drops, and its heartbeat and breathing slow down. It uses very little energy. In autumn, these animals get ready for winter by eating much more food than in summer and storing it as body fat. They use this fat to keep them alive while hibernating.Water makes good protection for many animals. When the weather gets cold, they move to the bottom of lakes and rivers. There, frogs and many fish hide under rocks or fallen leaves. Cold water holds more oxygen than warm water, and frogs can breathe through their skin.Every type of insect has its own life cycle and that is the way it grows and changes. Different insects spend the winter in different forms of their lives. Some insects also spend thewinter without moving. Some insects spend the winter as pupae（蛹）. Other insects die after laying eggs in autumn. The eggs change into new insects in spring and everything begins all over again.36.
