Recently I have joined in a discussion on the Internet about whether more MET opportunities should be provided each year. Of course, different people have different opinions on the issue. Some are in favor of this idea, while others express their worries about it.Those who are for this idea think that more test opportunities each year meets the need for MET reform. It allows students to have more chances and also helps reduce the stress of both parents and students.Those who feel worried believe that more test opportunities each year will add too much of a burden to both students and teachers. Besides, it will be a waste of money, labor and other social resources.As far as I am concerned, the more chances the better. More test opportunities each year will improve the fairness of MET.2. In the picture, a man is rowing a boat with great difficulty. However, the water in the river is too shallow for the boat to move on. Obviously, it is difficult to move the boat no matter how hard he tries.The picture tries to convey the message that it is important to build a solid foundation if we want to succeed. We can learn this lesson in real life. Take study for example. If we don’t have basic knowledge and essential ability, we may fail to achieve our goals even if we work hard. Just like the man in the picture, he can’t move forward as expected because water is not deep enough for the boat.Therefore, a good foundation is the key to success.。

One possible version:Learn from ThemNowadays more and more people have done a lot to protect the environment. Yesterday, I was glad to see m any students volunteer their time to make our school environment better. Some students picked up the trash on t he playground, some students planted the trees, and other students made posters calling on people to lead a low-carbon life.I was moved by what they did. The environmental protection is not only the business of the government, but also the responsibility of each of us. Even a small effort can make a great difference so I made up my mind to l earn from them.I will turn off the lights when I leave the room, and I won’t keep the wat er running when I am not using it. Besides, reusing some old things I plan to throw away will be my choice. What’s more, I will remind people arou nd me to take part in such activities.Action speaks louder than words.

One possible version:Nowadays, most middle school students have pocket money every month, and we did a survey in Class 1, Grade 9.As the result shows, among the thirty students taking part in the survey, most of them often buy snacks; about a half spend their pocket money on books, and a few save some of it.However, things on me are quite different. I usually spend most of the money buying good and educational books which I think make me moreknowledgeable. Only a small part is spent on snacks as most of the snacks are in fact unhealthy for us. And I save the rest against a rainy day.It is true that we have more and more pocket money now. Whether we can make good use of it really counts, because it is partly influencing the way we are growing up.中考英语作文评分标准听力录音材料:一、听对话,从下面各题所给的A、B、C三幅图片中选择与对话内容相符的图片。

He quickly finished his food on the plate and wentto his room upstairs.Later, he went down the stairs to look for something to read. In the deep silence, his mother sat alone on the living-room sofa. On her lap lay a photograph album. Looking up, she smiled 41 and said, “See what I found? Here’s your g reat-grandfather. He’s about your age in this picture. Do you think you look like him?”Joseph stuffed his hand into his pockets and shrugged(耸肩). He 42 the old key.As he moved closer to look at the photograph, something else 43 his eye. “What’s that?” he asked, pointing to a painted wooden box on the coffee table.“It’s a silent music box, “ his mother said softly. “Years ago, when I wasa little girl, 44 brother, 2 years older than me, took the key away. He didn’t mean to lose it. But he dropped it out somewhere, we searched and searched but 45 found it.”Joseph sat down beside her and handed the rusty key to her.Suddenly his mother’s eyes sparkled. With trembling hands, she wound up(转动) the music box. As its sweet melody played, mother and son listened together.“it has been silent for a long, long time,” she said.“It’s so clear!” said Joseph. “It sounds as good as new.” The silence had been 46 .35.

Lucy took it up and threw it into the air, but her brother didn’t pay attention and ran off, so the kite fell down. “Try again, children,” I said.Lucy once more took up the kite. But John ran off so suddenly that the kite flew out of her hand and it fell flat as before. “Try again,” said I.They did, and with more care, but a side wind came suddenly. As Lucy let go the kite, it was blown against some bushes and the tail was caught. Meanwhile, I went to the kite’s assistance and set the tail free from the bushes. I told them to find a more open area and then try again.We found an open area. I threw the kite up as John ran off. It rose up and promiseda high flight. But John was so pleased that he stopped short to look upward. The string became loose. The kite shook and came down to the ground. “I won’t try anymore. The kite won’t fly.” said he angrily. I replied, “A few disappointments are not supposed t o discourage us. And now try again.”And he tried and succeeded, for the kite was carried upward on the breeze as lightly as a feather. He was very excited to enjoy the sight. John began to roll up the string slowly. “Shall we come out tomorrow and try again?”I smiled, “Yes, dear children. I wish to teach you the value of keeping trying. Whenever you fail, remember---TRY AGAIN!”50. How many times did they fly the kite?A. Five B .Four C. Three D. Six51. How did John feel when he finally flew the kite up?A. AngryB. HopefulC. ExcitedD. Worried\52. The writer wants to tell usA. the ways of flying kitesB. the pleasure of flying kitesC. the cost of making mistakesD. the importance of keeping tryingCThere’s a lot of focus on trans fats(反式脂肪) these days. We read about it in the news, and there’s talk of passing laws against trans fats. We are bombarded with the word. Unfortunately, most people don’t know that trans fats truly are and why they are so bad for us. A lot of food production companies want to get your dollars by printing “Trans Fat Free” on their label(标签). Sadly, they may not be telling the truth.So what is a trans fats really? A trans fat is a liquid(液体)fat that is turned into solid. Although there is a very small amount of natural trans fats in meal and dairy products, most of them are created by adding hydrogen to light fat. Food-makers do this because it makes the products last longer on the shelf. Have you ever wondered why cookies can stil l be crispy and “tasty” after six months to a year on a store shelf? It’s because of trans fats. Trans fats are typically found in things like donuts, French fries, cookies, microwave popcorn, and potato chips.Why are trans fats bad for you? Trans fats raise the bad cholesterol(胆固醇) in your body and lower the good cholesterol that the body needs. Fatty foods do cause overweight. Trans fats build up in the body and block book flow to the heart. People whose diet contains a high percentage of trans fats are at risk of heart disease and stroke.Why can the food-makers label trans fats free when it isn’t? Because of the way the nutrition labeling laws work, the FDA(Food and Drug Administration) has allowed that if a food has less than 0 .5 grams per serving (一份) it can be classifiedas trans fats free. Read the label and you may discover that the package actually contains 6 servings, and if you just are three of them, you might have eaten 1.49 grams of trans fats.Besides, in most fast food restaurants, ingredient and nutrition informationare not listed. You may be shocked if you know what you are eating. An article in Men’s Health magazine pointed that in KFC, hydrogenated(氢化的) oils appeared 91 times among the ingredients from the menu list.How do you really know if there are trans fats in the food you are eating? Oneway to truly understand what you are eating is to read the label. Another is to understand your ingredients. Anything on the label that says hydrogenated orpartially hydrogenated, even if the package says “Trans Fats Free”, has trans fatsin it. You had better not buy that product. Make a different choice, a choice for your health.53. The expression “are bombarded with” in Paragraph 1 probably meansA. are tired ofB. hear much ofC. are connected withD. know clearly about54. Which of the following is true according to the passage?A. Trans fats can make food last long and keep people fit.B. Food-makers use trans fats because they make food deliciousC. The amount of trans fats in food is clearly written on the labelD. Trans fats can be found in the food with package saying trans fat free.55. What can be the best title for the passage?A. Danger of Eating Trans Fats FoodB. Truths and Facts about Trans FactsC. Buy Trans Fats Free Products Now!D. Don’t Eat in Fast Food Restaurant!DThe “halo effect” is a classic finding social psychology. It is the idea that general evaluations(评价) about a person (e.g. she is likeable) influence judgments about their specific traits(品质)(e.g. she is intelligent). Hollywood stars givethe perfect example. Because they are often attractive and likeable, we naturally consider they are also intelligent, friendly and so on. That is, sometimes, not true.In the 1970s, well-known social psychologist Richard Nisbett set out to provethe fact that we actually pay little attention to our thought processes in general, especially to the halo effect.Nisbett wanted to examine the way students made judgments about teachers. Theyhad been divided into two groups to watch two different videos of the same teacher,who happened to have a strong Indian accent. One group watched the teacher answera series of questions in an extremely warm and friendly manner. The second groupsaw exactly the same person answer exactly the same questions in a cold and distantmanner. In one the teacher appeared to like teaching and students, and in the other he came across as someone powerful who didn’t like teaching at all.After each group of students watched the videos they were asked to evaluate the teacher on physical appearance, mannerisms and even his accent (mannerisms were kept the same across both videos). The same as the hale effect infers, students who saw the “warm” one evaluated him more attractive, his mannerisms more likeable and even his accent as more pleasing. This was unsurprising as it backed up the idea s on the halo effect. At the same time, for those who had seen the other video, the result was just the wrong way around.The surprise is that students had no clue why they gave one teacher higher evaluations. Most said that how much they liked the teacher had not influenced their evaluation of his individual traits at all.The halo effect is fascinating and now well-known in the business world. For example, books that have “Harvard Classics” written on the front can ask twice the price of the exact same book without it. The same is true in the fashion industry.So the next time you consider buying a pair of designer jeans or decide whether you like someone, ask yourself whether the halo effect is operating. Are you really evaluating the traits of the person? This simple check could save you wasting your money or refusing a royal friend. Or perhaps, even if you do check, you’ll still never know.56. Why does the author mention Hollywood stars in the first paragraph?A. To help us to evaluate others.B. To explain what the halo effect isC. To show us the background of the storyD. To tell us Hollywood stars are not truly friendly57. Which one do you think is NOT an example of the halo effect?A. You make friends with the people who have good judgmentsB. You prefer to buy the products advertised by a movie starC. You pay more for a simple T-shirt with a famous designer’s name on it.D. You believe your teachers are intelligent because they appear likeable58. What can we learn from the passage?A. People can do nothing to avoid the halo effectB. People use the halo effect widely in the business worldC. People often wonder how the halo effect works before shoppingD. People sometimes don’t realize the halo effect when they make judgments59. The passage is mainly aboutA. the cause of the halo effectB. the development of the halo effectC. the evaluation of the halo effectD. the influence of the halo effectI’ve been singing and performing poems since I was six years old. I used to sing for my mother’s friends.60I have written three books of poems and songs. I gave all the money from the books to children’s cha rities. 61 Money from the second book was spent on homeless children in Bosnia.I visit patients at a local hospital every Saturday morning. I talk and sing for them. I guess that’s what’s really fulfilling(令人满意的)to me when I sing to someone who is dying , and someone who is really sick and who doesn’t even know what’s happening.62Everyone can give love, and love is what everyone wants. That’s a really important lesson to me. 63 Making someone happy makes you happy, and they go on and make others happy and it’s like a chain(链). You change when you get older, but love is ageless. Love is the same when you are7, 13, or 102 years old.A. Love is a chain of givingB. But now I am singing for people in needC. I visit people in the old people ’s homeD. Money from my first look went to a school for deaf kids in MontanaE. I feel proud when I see a smile on that person’s faceLearning to understand your mother well is what you should do. Here are the best tips towards a better relationship with her. They are not necessarily surprising, but they have worked for many people. Try them.Taking any measure to understand our mother is the topic of how we understand ourselves. We should follow the way of her life. When we are able to accept our mother —with all her failings, we can understand her better and it can also helpus to know about our shortcomings. Remember that understanding our mother is really about understanding ourselves.64. Should we learn to understand our mother well?65. What can help us understand our mother better?66. How do we make our mother feel close to us?67. Why do we ask our mother about our childhood history?68.

D―You don‘t have to be great to get started, but you have to get started to be great.‖ I believe it is thought normal in today‘s society to just let life happen to us. I also believe that we sometimes damage our well-planned thoughts about success because it is easier to just carry on as usual rather than ‗try‘ with the possibility of failure in mind.The main reason why most people never get moving is because they have no real idea about what they want. Without a certain result already set in your mind, it is really difficult to get going, and even if you do, your motivation (动力) may soon disappear and you give up before too long. Why not consider what is really important in your life? Write down what excites you, what would truly make you happy and what problems you have. At the end of the week, take a careful look at the notes you have taken. You will soon begin to see a clearer picture of what direction you should be heading.Knowledge is useless without action. You can read every book on any subject but your life will stay the same if you do not use that knowledge. This may seem clear but the reason why the self-help industry is thriving (繁荣的) is because people read and r ead and read but never use the information provided.Knowledge is fantastic but it is not life changing until used. I love to read personal development material to keep a positive attitude towards my life, but I also re alize that if I don‘t set goals to achieve, then I will always be a talk the talk person who is great at giving advice but useless at realizing it. If you have no plans of practicing what you say, then it may be best to keep your mouth closed.Do you want to know who you are? Don‘t ask. Act! Action will explain you. Whatever excuses we have for not living up to our talent, the fact is that time will always move forward. Be whatever you want to be and whatever you can be. Always remember the only limits we have are the ones we create for ourselves. Life is not what we think, it is what we experience when we act upon the thoughts we entertain.58. In Paragraph Two, the writer wants to ________.A. tell us what people need to get successB. show us what people set in their mindC. inform us why people should practiceD. explain why people stop going ahead59. The underlined phrase ―living up to‖ probably means ________.A. matchingB. showingC. wastingD. losing60. What is the best title for the passage?A. See a Clear Picture of Life.B. Get Started to Be Great.C. Set Goals to Achieve.D. Act upon Thoughts.58. D 59. A 60. D阅读理解(共44分)DShe was only about five feet tall and probably never weighed more than 110 pounds, but Miss Bessie was a towering presence in the classroom. She was the only woman tough enough to make me read Beowulf and think for a few stupid days that I liked it. From 1938 to 1942, she taught me English, history — and a lot more than I realized.I shall never forget the day she scolded (批评) me into reading Beowulf. ―But Miss Bessie,‖ I complained, ―I ain‘t much interested in it.‖Her large brown eyes became sharp. ―Boy,‖ she said, ―how dare you say ‗ain‘t‘ to me! I‘ve taught you better than that.‖―Miss Bessie,‖ I said, ―I‘m trying to join the football team, and if I go around saying ‗it isn‘t‘ and ‗they aren‘t,‘ the guys are gonna laugh me off the team.‖―Boy,‖ she replied, ―you‘ll play football because you have guts (勇气). But do you know what really takes guts? Refusing to lower your standards to those of the crowd. It takes guts to say you‘ve got to live and be somebody fifty years after all the football games are over.‖I started saying ―it isn‘t‖ and ―they aren‘t,‖and I still joined the team without losing my friends‘ respect.Negroes, as we were called then, were not allowed in the town library, except to sweep floors or clean tables. But with the help of some nice whites, Miss Bessie kept getting books out of the white library. That is how she introduced me to the Brontës, Byron and Keats. ―If you don‘t read, you can‘t write, and if you can‘t write, you might as well stop dreaming,‖ Miss Bessie once told me.So I read whatever Miss Bessie told me to, and tried to remember the things she insisted that I store away. It could be embarrassing to be unprepared when Miss Bessie said, ―Get up and tell the class who Frances Perkins is and what you think about her.‖ Forty-five years later, I can still recite her ―truths to live by‖.Miss Bessie noticed things that had nothing to do with schoolwork, but were essential to a youngster‘s development. Once a few classmates made fun of my worn-out hand-me-down overcoat. As I was leaving school, Miss Bessie patted me on the back of that old overcoat and said, ―Carl, never worry about what you don‘t have. Just make the most of what you do have —a brain.‖No child can get all the necessary support at home, and millions of poor children get no support at all. This is what makes a wise, educated, warm-hearted teacher like Miss Bessie so essential to the minds, hearts and souls of this country‘s children.57. The underlined words ―towering presence‖ in the first paragraph means _______.A. Miss Bessie was strong enough to influence her studentsB. Miss Bessie was watching the students all the timeC. the students thought she was tall and heavyD. the students felt nervous in front of her58. What can we infer from the passage?A. Carl‘s friends c ame from poor families.B. Carl hated to read Beowulf in public.C. Miss Bessie wanted Carl to be a better man.D. Miss Bessie didn‘t want Carl to play foot ball.59. Miss Bessie asked Carl to read a lot because _______.A. his parents were too poor to afford booksB. he was not allowed into the libraryC. the whites didn‘t want the blacks to readD. she expected him to have a goal in life60. Which of the following would be the best title of the passage?A. Dreams Go with EducationB. An Unforgettable LessonC. Unforgettable Miss BessieD. Reading Makes a Full Man57. A 58. C 59. D 60. C东城:DBreakfast is the most important meal of the day, but many people don‘t have it. Common reasons for not eating breakfast include shortage of time, not feeling hungry, traditional dislike for breakfast, and dieting(节食).Breakfast simply means ―break the fast‖. You eat nothing for at least 6 to 12 hours each night. Even though you have been sleeping, you have still been burning energy. And in the morning your body needs energy for the day‘s work ahead.A good breakfast should provide up to 1/3 of your total calories(卡路里)that your body needs for the day. Generally speaking, we eat 400 less calories for breakfast than for dinner. If breakfast doesn‘t interest you in the morning, try eating a lighter dinner earlier in the evening or save half your dinner for breakfast in the morning.If you still aren‘t hungry in the morning, start with something small like juice or bread or have nutritious(有营养的)mid-morning snack later when you are hungry.So, you say you‘re on a diet. Some people are afraid that eating breakfast will make them hungrier during the day and they will eat more. It is true that eating breakfast is likely to make you feel hungry throughout the day. That‘s because your body is working correctly. Although you may feel as if you are eating more all day long, in fact you‘re probably not.Not eating breakfast may cause you to overeat, because a fall in blood sugar often makes you feel hungry later. To make things worse, since your body is in a slowed state, it will not be able to burn those extra calories well. If you feed your body healthy snacks and meals throughout the day, you may not become hungry so easily and eat too much when you have meals.Since breakfast is the first and most important meal of the day, your choice is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as bread, rice, noodles and cereals.58. The underlined word ―fast‖ means ―a period during which someone ________.‖A. moves quicklyB. works hardC. goes without foodD. sleeps in bed59. From the passage, we know that ________.A. breakfast provides us most of the energyB. breakfast may help to save the dinnerC. breakfast might make people overeatD. breakfast helps our body work well60. What is the best title for this passage?A. Breakfast and EnergyB. Why Not Eat BreakfastC. Breakfast and DietingD. What to Eat for Breakfast57. A 58. C 59. D 60. B朝阳:DChristmas is a time for shopping. But I think those of us who live in large ci ties in Asia would be cheating ourselves if we said this is the only time we are busy shopping. No, from Bangkok to Singapore, from Shanghai to Manila, shopping—especially shopping in large centers—is a year-round activity.Shopping centers are good. They show Asia‘s surprising economic (经济的) growth, and how far we have come in such a short time. For many of the older generation who can remember a time when everyone lived in villages and there was no running water, the air-conditioned centre means comfort, choice, luxury (豪华) and better times.Nowadays, it seems our usual activities happen in the centre—it‘s where we shop, eat, watch movies, meet our friends or just generally walk around.Further more, we have come to regard shopping centers as important landmarks or tourist attractions(吸引). Whole generations of Asians are growing up to think that, besides home and school, the shopping center is the most natural place to be.My idea about shopping centers is not that they are often big buildings that look quite different from other parts in a city, or that they promote (促进) shopping at a time when our planet can hardly afford it. My main idea about centers is that they don‘t really seem to make us happy. The large advertisements outside the stores could make us think that if we only had this pair of jeans, or if we hung out at this café drinking coffee, then we could feel more successful. But once we buy something, we only want to buy something more—as everyone already knows.Shopping centers, even though they try to look as welcoming as possible, can be unkind places. To make us buy, they must make us feel that we are short of something, or that everyone else has something we do not yet own. We must want to surpass others or at the very least to keep up. How can this thought always trying to be cool bring us true joy?The saddest thing is that the modern centre has stopped us from many beautiful, necessary and important activities. We have no one to blame (责怪) but ourselves. Instead of shopping, we could be cooking, visiting a nearby waterfall, going to the beach, reading a novel, taking a long walk, playing a sport, learning a dance or visiting each other‘s homes.Every time we have a spare piece of land, all we can think of building on it is yet another centre. Perhaps instead, we should be building libraries, theatres, museums, sports halls, public swimming pools, parks—the list is endless. We might even consider leaving t hat land alone. This is something that the centre may have caused us to forget—in order to be happy, we must create as well as consume (消费).57. What is the writer‘s attitude towards shopping centers?A. He likes them very much.B. He doesn‘t like them at all.C. He likes them only a little.D. He doesn‘t like all of them.58. Why do more and more shopping centers appear in some Asian countries?A. Because economy in the world develops very fast.B. Because shopping centers have attracted tourists all over the world.C. Because people go shopping in large shopping centers all year round.D. Because shopping centers have become an important part in everyone‘s life.59. What is the greatest disadvantage of shopping centers, according to the writer?A. They don‘t seem to make us happy.B. They lead us to buy more and more things.C. They force us to give up many other activities.D. They have us fall into endless competition with others.60. Which of the following is not true?A. It is very easy for us to find a shopping centre in a big city.B. There are usually all kinds of services in a shopping center.C. The government must be responsible for the writer‘s sadness.D. Besides shopping, there‘re many other activities we can enjoy.朝阳答案:(D)57 B58 D59 C60.C石景山:DDo you know that women‘s brains are smaller than men‘s? Normally t he women‘s brain weighs 10% less than men‘s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聪明的)than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it‘s what‘s inside that matters, not just the size of the br ain. The brain is made up of ―grey matter‖ and―white matter‖. While men have more of the white matter, the amount(数量)of ―thinking‖ brain is almost the same in both men and women.It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it‘s women who come out on top every ti me.There are other important differences between two sexes(性别). As white matter is the key to spatial(空间的)tasks, men know better where things are in relation to other things. ―A great footballer always knows where he is in relation to the other players, and he knows where to go,‖ says one researcher. That may exp lain one of life‘s great mysteries: why men refuse to ask for directions … and women often need to!The differences begin when fetuses(胎儿)are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain thefact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.57. Which of the following is TRUE according to Paragraph 1?A. Grey matter controls thinking in the brain.B. M en‘s brain is 10% less than wo men‘s.C. Grey matter plays the same role as white matter.D. Men and women have the same amount of white matter.58. What can you infer from Paragraphs 2 and 3?A. Men have weaker spa tial abilities.B. Women do not need to tell directions.C. Women prefer doing many things at a time.D. Women do many jobs at a time better than men.59. What can you learn from Paragraph 4?A. Our children needed more spatial skills.B. Women may have more feelings than men.C. Young boys may be stronger than young girls.D. More women take up jobs requiring speech skills.60. The passage is mainly about _______.A. ways of being more intelligentB. differences between men and womenC. studies on brains between two sexesD. studies on white matter and grey matter57. A 58. D 59. D 60. C昌平:DCan you imagine the very first modern Olympics in 1896 with no landing mats (海绵垫), no stopwatches and no photo finishes? In fact, c ameras and stopwatches were not used until the 1932 Olympic Games in Los Angeles, USA. Thanks for technology, Olympics have been developing at an unbelievable speed.Today technology has completely changed sports. Take sports equipment for example. Electronic eyes hanging at the starting lines, together with digital cameras, could catch correct race time and also h elp to catch runners who ―jump the gun‖. As runners cross the finishing line, special digital cameras can also easily decide the winner. The days of―dead heats‖ are gone.Technological developments are also good for athletes. New sportssuits, which get less wind effects, can help cut up to one-tenth of asecond from runners‘ race time. Top athletes, like Liu Xiang, are evenprovided with hand-made sports shoes. These shoes are made to fit theathlete exactly -- and there are some more changes in the shoes thatmeet each runner‘s personal needs.Technology has also changed the way of many sports. Take one example -- the pole vault. The landing mat makes a big difference to the vaulting style as athletes no longer need to worry about hurting themselves as they fall. Without these worries, athletes could jump higher. New swimming pools have been used to help swimmers swim with easier effort and sports scientists have worked out a new swimming style to improve the speed.The increasing technological developments have led many sportsmen to suggest that the ―Olympic spirit‖ is being lost in a rush to break records and win medals. Many developing countries say that technology has become too important in sport and that athletes from developing countries are disadvantaged. There are no easy answers but one thing is sure -- we cannot turn back times. Technology cannot go backwards.The underlined phrase ―dead heats‖ means __________.A. sports equipment which was out of dateB. runners who jumped the gun while runningC. diseases which killed runners in hot weatherD. races in which runners finished at the same timeWhat infers from the fourth paragraph?A. Scientists can measure the speed of swimming.B. The pole vault was not quite safe in the past.C. Pole vaulters jump lower with landing mats.D. New pools have changed the style of swimming.The purpose of the writer in writing this article is _______.A to suggest we should keep up with the timesB to suggest we reduce technology in OlympicsC to suggest we train better athletes like Liu XiangD to suggest we care more about developing countries58-60 DBA房山:DWhat's your dream vacation? Watching wildlife in Kenya? Boating down the Amazon? Sunbathing in Malaysia? New chances are opening up all the time to visit the world. So we visit travel companies, compare prices, and pay our money.We know what our vacation costs us. But do we know what it might cost someone else? It's true that many poorer countries now depend on tourism for foreign income. Unfortunately, though, tourism often harms the local(本地的) people more than it helps them.It might cost their homes and lands. In Myanmar, 5,200 people were forced to leave their homes among the pagodas(佛塔) in Bagan so that tourists could visit the pagodas.Tourism might also cost the local people their jobs and dignity(尊严). Local workers often find only low-paying jobs in the tourist industry. And most of the money do not help the local economy(经济). Instead, money return to the tour operators in richer countries, When the Maasai people in Tanzania were driven from their lands, some moved to poor places of the city. Others now make a little money selling things or acting for photos.Problems like these were noticed more than 20 years ago. But now tour operators and localgovernments are working together to begin correcting them. Tourists, too, are putting on the pressure.The result is ―ethical(合乎职业道德的)tourism‖. Ethical tourism has people at its heart. New international agreements and rules can help protect the people's lands, homes, economies and cultures. The beginnings are small, though, and the problems are complex(复杂的).But take heart. The good news is that everyone, including us, can play a part to help the local people in the places we visit. Tour operators and companies can help by making sure that local people work in good conditions and earn the money they should get.They can make it a point to use only locally owned hotel, restaurants and guide services. They can share some money to help the local economy. And they can help the local people plan and manage tourism.What can tourists do? First, we can ask tour companies to provide information about the conditions of local people. We can then make our choices and tell them why. And while we're abroad, we can:Buy local foods and products.Pay a fair price for goods and services and not bargain for the cheapest price.Ask before taking photographs of people.They are not just part of the scenery!Let's enjoy our vacation and make sure others do, too.57. Which of the following is not mentioned?A. Local people protected the pagodas in Bagan well.B. Tourists may stay in hotels opened by local people.C. Local people are mainly provided with low-paying work.D. Tourists had better not bargain with local people for a cheap price.58. The underlined phrase "take heart" means" ".A. pay attentionB. take careC. cheer upD. give up59. According to the passage, the writer thinks .A. tourism is not a promising industryB. dream vacations should be spent abroadC. the problems caused by tourism are easy to settleD. tourists should respect local customs and cultures60. What is probably the best title for the passage?A. Tourism Causes Bad Effects.B. Tourism Calls for Good Behavior.C. Vacations Bring a Lot of Fun.D. Vacations Cost More Than You Think. 57.A 58.C 59.D 60.D平谷:DPeople cannot reach an agreement on the use of science and technology. For example, will radiation from electronic equipment destroy the environment? Should medical scientists change gene structures to prevent genetic disease or to create ―more perfect‖ human beings? While people are arguing about these and others, technology continues to influence our everyday lives—thehome, health and education, entertainment and communication, and so on.Some people carry on active social lives with computers —their own or the ones in public places like cafes, social centers, libraries, and so on. Communicating with others in chat rooms, computer users can get to know people they might never meet in traditional ways. With live online video connections, two people with cameras in their computers can see and talk to each other from separate places.With modern telephone technology, most people stopped writing lettters—especially personal letters and notes. But now, writing to communicate has returned in electronic form, or e-mail, which is a way of sending messages from one computer to another. For some computer users, the wish to communicate intelligently or creatively with others makes them want to write better.Computer technology has also made it possible to run a house electronically. From turning lights on and off to starting the coffee and cooking the hot meal, computers are taking care of people at home. Many modern machines ha ve computer chips that allow their owners to program them. For instance, you can ―instruct‖ a microwave oven how to cook a dish. Most entertainment equipment operates with computer technology too. Computers can even start cars automatically so that on cold winter mornings you can get into a warmed-up vehicle and drive off.Although much of th e technology in our everyday lives has good effects, there are some uses that raise questions. For example, are interactive media ( i.e., a combination of television, telephone, and computer) going to control minds, cause people to forget about family life and personal relationships? What effects will the genentic engineering of food have on people‘s health? High-tech medical treatments can make a person live a much longer life, but can they improve the health and happiness of human beings? Only time will tell, but, in the meantime, science and technology will continue to move forward.57. What does the underlined word ― chips‖ mean?A. thin pieces of potatoesB. small holesC. small pieces of woodD. central parts58.We can know from the passage that _________.A. technology never stops changing our everyday livesB. with computers each of us can live a comfortable lifeC. people can do more activities with computersD. the more you use computers, the better you might write59. What can we infer from the underlined sentence in the last paragraph?A. The longer you live, the happier you are.B. High-tech medical treatments can‘t improve our health and happiness.C. High-tech medical treatments can‘t help us with everything.D.The writer questioned high-tech medical treatments somehow.60. What is the best title for the passage?A. Science and New TechnologyB.

The young oranges are growing well in Florida‘s weather. Warm sunshine and gentle rains, along with Ed Rawlings‘expert care, will produce a good crop(收成)of oranges this year.However, Ed has to guard against Florida‘s changeable winter weather. In January and February, temperatures can destroy Ed‘s entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer(层) of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops.But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity(数量)of water must be used. Too much water can form a thicker layer of ice that will break the tree‘s branches(树枝). Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.Computer techn ology may help Ed with some of these worries. With equipment(设备), air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate(计算) when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently( ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits(利益) of computer—age oranges.58. The passage is mainly about______.A. a farmer expert cares for his orange treesB. the different uses of computersC. growing oranges in Florida‘s changeable weatherD. different ways of frost protection59. Ed tries to protect his crop by______.A. using a wind machine to drive away the cold airB. equipping his orange trees with a computerC. watering it at the proper timeD. picking his fruit at the first sign of frost60. According to the passage, the computer technology______.A. removes the need for frost protectionB. prevents temperature from droppingC. tells farmers why outdoor temperatures changeD. helps the farmer get a better harvest58.

Luckily, you don‘t have to sign up for classes to learn how to enhance(加强) your SQ. Here are some simple steps that can lead you to this new level of understanding:Sit Quietly. The step of developing SQ begins in solitude (独处)and silence. To tune in to its whisper, you have to keep away from your busy, n oisy, complicated life and make yourself do nothing at all. At home, for example, shut the door of your bedroom, take a few deep breaths and let them out very, very slowly.Step Outside. For many people, nature makes their spirit free. Go outside to watch a beautiful sunset. Follow the flight of a bird; watch clouds floating overhead.Find An Activity You Enj oy. It‘s important to find a hobby that helps you tune in to your spirit. Garden, walk or jog, arrange flowers, listen to music that touches your soul.Ask Questions Of Yourself. Some people use their thoughtful time to focus on scriptures (经文). Others ask open-ended (无确定答案的) questions, such as ―What am I feeling? What are my choices?‖ But don‘t expect an answer to arriv e through some super-natural form of e-mail. Later that day you‘ll suddenly find yourself thinking about a problem from a perspective(角度) you never considered before.Trust Your Spirit. While most of us rely on gut feelings (直觉) to warn us of danger, SQ usually nudges (渐渐推动)us, not away from, but toward some action that will lead to a greater good.57. To enhance your SQ, you should first _______________.A. stand loneliness and silenceB. make your life simpler and less busyC. give up the daily things in your lifeD. listen more to your whisper58.The underlined phrase “tune in to your spirit”in the fifth paragraph probably means ________________.A. get your spirit relaxedB. keep up your spiritC. listen to your spiritD. change your spirit59. What will happen after people ask questions of themselves?A. People will lead to a greater good.B. People will think about a problem in a different way.C. People will expect answers through e-mails.D. People will keep away from their busy life.60. What is the best title for the passage?A. Advantages and disadvantages of SQB. The relationship between your SQ and youC. What SQ is and in what ways it can be improvedD. What SQ is and in what ways you can make your life easier BABC。

The leaves fluttered (飘扬)over John's head.He liked to watch the colors of the trees shine through the sunlight.It was the same color as his trumpet.John smiled when he thought of the music the leaves made.He looked at his watch; his father would meet him in a few minutes for their first practice in the park.John and his family lived in an apartment building.He began playing his trumpet in his own living room two weeks ago.Then the family next door had a new baby.To keep from waking up the baby, John was going to spend his practice time in the park.Although he enjoyed visiting the park, he didn't want to practice his music there.John was afraid that he would embarrass himself if he played the wrong notes.And he imagined his cheeks looking like a red, blown﹣up balloon.He didn't want people to watch him as he practiced his music.Unluckily, his father couldn't possibly understand how embarrassing it would be!"John, are you ready? "pulling him out of his daydream, his father sat down and began to play his trumpet.John looked up at a golden tree.The leaves seemed to be dancing with the tune.He felt excited as he watched the people walking by and smiling at his father.He wanted to play like that!Immediately, John placed his trumpet to the mouth and blew.Soon, John was having such a great time playing with his father that he didn't care if he had played a few bad notes.The golden tree was dancing while John was still playing.Now he and his neighbors could both be happy.(1)To keep from waking up the baby,John practiced his trumpet________.A in the buildingB in the streetC in the parkD in the room.(2)John didn't want to practice his music outside because________.A his next door neighbor had a new babyB his father didn't play together withhim C he didn't enjoy going to the public park D he was afraid to play some wrong notes.(3)How did John feel when his father was playing?________A Interested.B Excited.C Afraid.D Bored..(4)Which of the following statements is TRUE according to the passage?________A John was sorry to wait for his father to come.B John was willing to be watched by many people.C John experienced true happiness brought by music.D Johnrefused his father's invitation to play the trumpet..19. Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12to 17use the Internet, and 51% of those teens use social networks.However, there are many possible problems with social networking sites and the teenagers who use them.Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation.They provide a way to communicate with others who share the same interests and to get helpful advice on ongoing projects.Along with these advantages come some dangers.For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America.It means that they could be put in unpleasant and frightening situations. A greater danger is that teens may become objects of the people with secret purposes.The secrecy of some social networking sites makes it easy for dangerous peopleto find young teens and invite them into dangerous conversations.It's easy for them to pretend as teens and draw children into dangerous real﹣world communication as well.Then further hurt might be on its way.Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.Therefore, it's very important to make sure teens are safe when they use social networks. Many of the same rules that work for online chat work for these sites:※Don't use your real name.※Don't give out personal information to people you don't know.A last name and a townare enough for a bad guy to find where you are.※Don't believe that people are who they say to be.※Immediately end any communication that makes you uncomfortable and report it to aparent.Only if you are sure of your safety, can you enjoy the fun brought by social networking.Besides, trying to deal with all problems on your own can lead to terrible results.Remember, asking your parents or school officials for help doesn't mean you are unable to do anything but wiser than many others.(1)How many dangers of using social networks are mentioned in the passage?________A 2.B 3.C 4.D 5..(2)The writer takes MySpace as an example to show that________.A students could be put into unreal situations on the InternetB teenagers are facing unknown dangers on the social networksC Internet provides more social websites to American teenagersD social networks are very popular among teenagers in America.(3)We can infer from the passage that________.A the dangers are similar when chatting online and surfing social networksB more than half American teenagers aged from 12to 17use social networksC teens who ask for help are wiser when meeting problems on social networksD there are more disadvantagesthan advantages for teens to use social networks..20. "You don't have to be great to get started, but you have to get started to be great."I believe it is thought normal in today's society to just let life happen to us.I also believe that we sometimes damage our well﹣planned thoughts about success because it is easier to just carry on as usual rather than‘try'with t he possibility of failure in mind.The main reason why most people never get moving is because they have no real idea about what they want.Without a certain result already set in your mind, it is really difficult to get going, and even if you do, your motivation (动力) may soon disappear and you give up before too long.Why not consider what is really important in your life? Write down what excites you, what would truly make you happy and what problems you have.At the end of the week, take a careful look at the notes you have taken.You will soon begin to see a clearer picture of what direction you should be heading.Knowledge is useless without action.You can read every book on any subject but your life will stay the same if you do not use that knowledge.This may seem clear but the reasonwhy the self﹣help industry is thriving (繁荣的) is because people read and read and read but never use the information provided.Knowledge is fantastic but it is not life changing until used.I love to read personal development material to keep a positive attitude towards my life, but I also realize that if I don't set goals to achieve, then I will always be a talk the talk person who is great at giving advice but useless at realizing it.If you have no plans of practicing what you say, then it may be best to keep your mouth closed.Do you want to know who you are? Don't ask.Act!Action will explain you.Whatever excuses we have for not ________ our talent, the fact is that time will always move forward.Be whatever you want to be and whatever you can be.Always remember the only limits we have are the ones we create for ourselves.Life is not what we think, it is what we experience when we act upon the thoughts we entertain.(1)In Paragraph Two,the writer wants to________.A tell us what people need to get successB show us what people set in theirmind C inform us why people should practice D explain why people stop going ahead.(2)The underlined phrase"________"probably means________.A matchingB showingC wastingD losing.(3)What is the best title for the passage?________A See a Clear Picture of Life.B Get Started to Be Great.C Set Goals to Achieve.D Act upon Thoughts.七、阅读短文,根据短文内容,从短文后的五个选项中选出能填入空白处的最佳选项.选项中有一项为多余选项.(共8分,每小题8分)21.

Are you a twin?And if so,are you a"double"too?Then Ohio,the United States is the place for you to be for an August weekend of twin fun.Every year,in August,twins from all over the world get together in Ohio,for a special day﹣﹣the Twins Day Festival offeredto twins and for a weekend of socializing,celebration and fun.The Twins Day Festival at Twinsburg is the world's largest gathering of twins everyyear.It's a big club﹣like event in which twins and their parents come to this small town.The first Twins Day Festival was held in 1976with only 37pairs of twins.That year,the United States celebrated 200years of independence,and then a group of people decided toset a day for twins.The directors did not want the festival to be a one﹣off celebration.So the next year,they planned it better and made sure that the festival continued at the same place.Since then,this festival has been held without fail,drawing twins from every corner of the world.However,there used to be heated arguments whether Twins Day should be only a local celebration or a festival for children of multiple births.In 1979,the festival went international with two sets of twins arriving from Lebanon and Poland.In the same year,the Twins Day Committee was formed as a non﹣profit organization.Today,the Twins Day Festival attracts 2,736pairs of twins from every state in the USA and others from all over the world,from baby twins to people in their eighties and nineties! 65.Is the Twins Day Festival held in August every year?________66.Where is the world's largest gathering of twins held?________67.Why did the directors plan the festival better the next year?________68.When did the festival go international?________69.What are the main points about the Twins Day Festival in this passage?________.九、完成句子(共10分,每小题2分)根据中文意思完成句子.23. 苏珊一到学校我们就出发.We will set off________ Susan gets to school.24. 爷爷奶奶很高兴今年暑假我要去看望他们.Grandparents________ that I will visit them this summer vacation.25. 您愿意本周六和我一起看电影吗?________ go to the cinema with me this Saturday?26. 我上周用了两天时间为妈妈选了一件礼物.________ find a present for Mom last week.27. 这里的景色太美了,我们停下来拍了很多照片.The sights here were________.十、文段表达(共15分)根据中文提示和图表内容,写一篇意思连贯、符合逻辑、不少于60词的文段.文段的开头已给出,其词数不计入所完成的文段内.请不要写出你的校名和姓名.28. 现在的中学生每月都有一定数量的零花钱.某校对九年级(1)班的30名学生进行了零花钱用途的调查.结果如下:有的同学常买零食或书籍,有的同学把钱花在手机或其他方面,也有的同学把零花钱存了起来.请你任选图表中的2至3项简述调查结果,谈谈你是如何支配零花钱的,并说明理由.Nowadays,most middle school students have pocket money every month,and we did a survey in Class 1,Grade 9.________.2011年北京市海淀区中考英语一模试卷答案1.
