As I got older I began doing random things for people. For example, during holidays, such as Christmas, I would make an extra 21 along with the ones for my relatives. Then I would go and find someone in the grocery store and just hand it to them and walk away. It was so much fun. I admit, 22 , the first time I did it I was so 23 . I didn’t know who to give the card to. So I said a little prayer and knew that the 24 person would just appear. About that time an elderly man ran 25 me with his shopping cart. It was an accident, and he 26 a million times. We smiled and he walked away, and I knew that he was the one. Later I found him in a different isle(过道), handed him the card, and smiled. I said Happy Holidays, and then walked away. It was so great, and the 27 I had afterwards was unexplainable. Then one day I came across your?website (the coolest?website ever) and 28 some Smile Cards. When they came in, I started a new project. When I go into a store, I locate a person who I think needs a29 . Then, I buy a flower, a carnation, to be exact, and 30 it in the most beautiful paper they have. I tie lots of ribbons on it to make it 31 , and then slip the smile card into an envelope and 32 it to the flower. After that, I pay for it and explain to the cashier 33 it is to go to (I live in a pretty small town so it’s easy to get the help of the cashiers). They then give it to that person when they come through. Once in a while I’ll buy the flower and then just leave it for the cashier. That gets smiles. My favorite time was when I picked out this elderly woman who was walking around the 34 somewhat confused. I had come across her numerous times and she only smiled slightly once. When she came to the check out (I was watching from outside) her face 35 and the smile was the biggest I had ever seen. Later that week the cashier whom I had had 36 me told me that the lady had been so surprised and while she was walking out with the grocery bag to her car, she was planning what she was going to do for someone else. It was awesome. I absolutely love the random acts of kindness cards. I 37 at least two in my purse and others in my car, locker and everywhere I go. As I mentioned, my club, STARS, is doing a Random Acts of Kindness Project with the smile cards so they also are using them. I look forward to hearing about their success. It’s really great. I 38 used them in school. I bought my entire math class cans of pop after lunch one day. They came in from lunch and a can of pop and a smile card were setting 39 that day. It totally lightened the mood in the class that day 40 we were studying for a test. Thank you for all of the help that you provide. The smile cards are a great program that brings smiles into the lives of many! 21. A. presentB. cardC. wishD. promise 22. A. thereforeB. anywayC. moreoverD. however 23.

A. because B. unless C. after D. whenever 阅读理解 (30分) A Have you ever picked a job based on the fact that you were good at it but later found it made you feel very uncomfortable over time? When you select your career, there's a whole lot more to it than assessing your skills and matching them with a particular position. If you ignore your personality, it will hurt you long-term regardless of your skills or the job's pay. There are several areas of your personality that you need to consider to help you find a good job. Here are a few of those main areas; 1) Do you prefer working alone or with other people? There are isolating(使孤立)jobs that will drive an outgoing person crazy and also interactive jobs that will make a shy person uneasy. Most people are not extremes in either direction but do have a tendency that they prefer. There are also positions that are sometimes a combination of the two, which may be best for someone in the middle who adapts easily to either situation. 2) How do you handle change? Most jobs these days have some elements of change to them, but some are more than others. If you need stability in your life, you may need a job where the changes don't happen so often. Other people would be bored of the same daily routine. 3) Do you enjoy working with computers? I do see this as a kind of personality characteristic. There are people who are happy to spend more than 40 hours a week on a computer, while there are others who need a lot of human interaction throughout the day. Again, these are extremes and you'll likely find a lot of positions somewhere in the middle as well. 4) What type of work environment do you enjoy? This can range from being in a large building with a lot of people you won't know immediately to a smaller setting where you'll get to know almost all the people there fairly quickly. 5) How do you like to get paid? Some people are motivated by the pay they get, while others feel too stressed to be like that. The variety of payment designs in the sales industry is a typical example for this. Anyway, these are a great starting point for you. I've seen it over and over again with people that they make more money over time when they do something they love. It may take you a little longer, but making a move to do what you have a passion for can change the course of your life for the better. 41. Which of the following is TRUE according to the passage? A. Isolating jobs usually drive people mad. B. Interactive jobs make people shy easily. C. Extreme people tend to work with others. D. Almost everyone has a tendency in jobs. 42. What does the underlined sentence in paragraph one mean? A. Before you select your job, you should assess your skills and match them with your position B. There are more important things than assessing skills and match them with the position when you select job. C. Nothing is important than assessing skills and match them with the position when you select job. D. You should ignore your skills when you select job. 43. What is the missing word about a job search in the following chart?A. Design.B. Changes.C. Cooperation.D. Hobbies. B I opened my new patient's chart and headed for her room. My son, Eric, had just brought home a disappointing report card, and my daughter, Shannon, and I had argued again about her getting a driver's license. For the next eight hours I wanted to throw myself into helping people who I knew had much more to worry about than I did.?Rebekah, mother of three lovely little girls, was only 32, admitted for chemotherapy after breast-cancer surgery, When I gave her an injection, Rebekah shut her eyes tightly and murmured a prayer until it was over. Then she smiled and squeezed my hand. “Before you go, could you get my Bible from the table?" I handed her the worn book. "Do you have a favorite Bible verse?" she asked. "Jesus wept. John 11: 35." "Such a sad one," she said. "Why?""It makes me feel closer to Jesus, knowing he also experienced human sorrow."?Rebekah nodded thoughtfully and started flipping through her Bible as I shut the door quietly behind me. During the following months, her hospital stays became frequent and she worried about her children.?One day when I entered her room, I found her talking into a tape recorder. She picked up a notebook and held it out to me. "I'm making a tape for my daughters, " she said. I read the list on her pad: starting school, confirmation, turning 16, first date, graduation. While I worried how to help her deal with death, she was planning for her children's future. She usually waited until the early hours of the morning to record the tapes so she could be free from interruptions. She filled them with family stories and advice,trying to cram a lifetime of love into a few precious hours. Finally, every item in her notes had been checked off and she entrusted the tapes to her husband. I often wondered what I would say in her place. My kids joked that I was like an FBI agent, with my constant questions about where they’d been and who they’d been with. Where, I thought, are my words of encouragement and love? It was three o'clock one afternoon when I got an urgent call from the hospital. Rebekah wanted me to come immediately with a blank tape. She was breathing hard when I entered her room. I slipped the tape into the recorder and held the microphone to her lips. "Ruthie, Hannah, Molly, this is the most important tape." She held my hand and closed her eyes. "Someday your daddy will bring home a new mommy. Please make her feel special. Show her how to take care of you. Ruthie, honey, help her get your Brownie uniform ready each Tuesday. Hannah, tell her you don't want meat sauce on your spaghetti. Molly, don't get mad if there's no apple juice. Drink something else. It's okay to be sad, sweeties. Jesus cried too. He knows about sadness and will help you to be happy again. Remember, I'll always love you.?I shut off the recorder and Rebekah sighed deeply. "Thank you, Nan, "You'll give this one to them, won't you?" she murmured as she slid into sleep.? A time would come when the tape would be played for Rebekah's children, but right then, after I smoothed Rebekah's blanket, I got in my car and hurried home. I thought of how my Shannon also liked her sauce on the side and suddenly that quirk, which had annoyed me so many times, seemed to make her so much more precious. That night the kids didn't go out; they sat with me long after the spaghetti sauce had dried onto the dishes. And we talked, without interrogations, without complaints,late into the night. 4From the first paragraph we can learn that ____________ . A. Nan was in a bad state and wept a lot in her daily life. B. Nan was not on good terms with her children. C. Nan was worried about how to help Rebeka deal with her death. D. Nan laid more stress on attending on her patients than her children. 45. Which of the following scenes was most likely to be seen at Nan’s home before she met Rebekah? A. The family sat down in a circle and shared an interesting story. B. After dinner, the children either went out or shut themselves up in their rooms. C. The son was the headache of the parents while the daughter their comfort. D. When Eric did poorly at school, the parents comforted him and cheered him up. 46. Which was the most vital message Rebekah left to her children? A. Bringing home satisfying school report cards B. Landing a job after graduation C. Growing up healthily and happily D. Accepting their step-mother into their lives. 47. The writer learnt from Rebekah that a parent’s real concern should be . A. protecting the children from the dangers they may be trapped in. B. having encouraging and loving talks with children. C. making tape records to guide the children in their future lives. D. tolerating the children’s annoying quirks. C The largest campaign of killing rats in history is set to poison millions of rats on the sub-Antarctic island of South Georgia. Scientists say the campaign planned for 2013 and 2014 will restore beautiful South Georgia to the position it once held as the world’s most important nesting sites for seabirds. It was sailors in the late 18th century who unintentionally introduced rats to what had been a fresh environment. “If we can destroy the rats, at least 100 million birds will return to their home on South Georgia,” says Tony Martin, a biology professor at the University of Dundee who was invited to lead the project. South Georgia is by far the largest island to get rid of animals that destroy native wildlife after being introduced deliberately or accidentally by people. Though rats and mice have done the most damage, cats, foxes, goats, deer, rabbits and other species have been targeted in the campaigns around the world. South Georgia is seven times the size of New Zealand’s Campbell Island, currently the largest area ever killing rats. The successful war against Campbell Island rats was carried our in 2001 with 132 tons of poison dropped from five helicopters. “New Zealand pioneered the techniques for ridding islands of rats and in fact our operation on South Georgia is based on New Zealand’s technology.” Says Martin. “Some New Zealanders will be helping our campaign, including our chief pilot, Peter Garden, who was also chief pilot for the projects at Campbell Island and Rat Island, in the Aleutian chain of the north Pacific.” The second and third stages in 2013 and 2014 will involve dropping as much as 300 tons of poison from the air onto every part of the island where rats might live. It is a huge operation, carried out during the stormy southern autumn when the rats are hungry and the risks of poisoning native wildlife are less than in the spring and summer months. “Ideally we’d do in winter but the weather makes that too risky,” Martin says. The ecological payback will be priceless. But Martin says, “The full benefits will take decades to arrive, because some of these birds are slow to hatch.” 48. According to the passage, how did the rats appear on the sub-Antarctic island of South Georgia ? A. They were attracted there by wildlife. B. They escaped there from Campbell Island. C. They were introduced there by sailors accidently. D. They were brought in by people deliberately. 49. Which of the following is True about Peter Garden ? A. He is in charge of the campaign on the sub-Antarctic island. B. He will be the only pilot for the project on the sub-Antarctic island. C. He will benefit a lot from the campaign on the sub-Antarctic island. D. He made great contributions to the project at Campbell Island and Rat Island. 50. The operation of ridding South Georgia of rats is to carried out in autumn because _________. A. the war against Campbell Island rats failed in all seasons except autumn. B. only then do the New Zealanders to help the operation have the spare time. C. rats then need more food and the operation does less harm to native wildlife. D. the poison kills rats more effectively than it does in any other season. 51. What can we infer from the passage?. A. The campaign of killing rats will benefit the native wildlife in a short time. B. Rats aren’t the only species to be blamed for the disappearance of wildlife. C. The first stage of killing rats on the sub-Antarctic island didn’t make great achievements. D. The campaign in South Georgia will fully follow in the footsteps of that on Campbell Island. D According to a study by SallieMae, 84 percent of undergraduate students have credit cards, and by the time they are seniors, they have accumulated US$4,100 in debt, on top of whatever student loans they may have taken out. Credit cards are the most convenient form of payment, and they are aggressively marketed to college students. Reportedly, a typical college student carries 4.6 credit cards and US$3,173 in credit card debt. Credit cards seem to be a fact of life, not just student life. In the long term, using a credit card properly and paying off the balance can help establish a card history and increase your credit score, which will come in handy when you need an important loan, for a house or car, for example. Your credit score can affect even unrelated things like insurance rates. Credit cards also offer more protection for users than debit cards (借记卡).Under federal law, the credit card holder is only responsible for the first US$50 in fraudulent(欺诈的)purchases in cases of theft or loss. However, debit card users are responsible for the first US$500. SallieMae found some good news in the fact that two thirds of students had discussed credit issues with their parents, but 84 percent said they needed more information. Those who didn’t get any guidance were more likely to be surprised when they found out how much they owed. While credit cards offer the easiest access to money, they make it easy to live outside your means. Less than a fifth of students surveyed paid off their balance every month, and carrying a balance brings finance charges, sometimes at a very high interest rates. SallieMae found that almost 40 percent of students chose their first credit card based on direct mail, which is probably why students get credit card offers in the mail. But when the credit card offers flow in, be sure that you read the fine print. Offers of low or no interest rates can disappear, leaving you a debt that climbs beyond your ability to pay it off. 52. What does the first paragraph imply? A. Most of the senior students are shocked to see how much they owed. B. Students can only take out loans from credit cards. C. Most of students’ loans come from credit cards. D. Credit cards have a bad effect on college students. 53. The underlined part “come in handy” in the third paragraph probably means “_______”.A. bring troubleB. make mistakesC. be importantD. be useful 54. According to SallieMae, what is the possible reason why students get so many credit card offers in the mail? A. Many students’ first credit card is based on direct mail. B. It costs the banks little to mail out credit cards. C. Students don’t like to go to the bank to open a credit card account. D. Banks have no other way to let students use their credit cards. 55. What is the theme of the third paragraph? A. The advantages of using debit cards. B. The similarities between credit cards and debit cards. C. The advantages of using credit cards. D. Credit cards are the most convenient form of payment. 任务型阅读 (10分) (每空填一词) Young people are definitely less courageous (勇敢的) than they were ago. Why is this? It’s because they are spoiled, and take for granted everything that they have or are given. Thirty years ago, there wasn’t nearly as much blatant (公然的) disrespect for elders, peers, or other people in general. At that time, young people were taught that to get anything or get anywhere in life, they’d have to work for it and earn it. If young people aren’t being taught the basics of respecting others, and aren’t being taught that they need to work to make a living, then where are they to learn courage? Courage isn’t necessarily about risking your life, for whatever reason. It is about being able to face any kind of hardship, and to make decisions and face the consequences of those decisions. Courage means being able to learn from hard times, and to take those lessons with you through life. It means having the resourcefulness (足智多谋) to find ways to deal with your problems yourself, and not being afraid to do so. Too many young people now rely on parents, siblings, older relatives and others to get them through life. Too often they turn to these figures whenever they get into trouble, and expect to have their problems solved for them. If we are to help our young people become more courageous, we should stop spoiling them, stop doing everything for them, and teach them the skills necessary to make basic life decisions on their own. Once these basic principles are instilled (灌输) in our young people, I think we’ll find that they are more courageous than we could have dreamed, and more like the young people of thirty years ago than we had ever imagined. It’s time to go back to older values and ideas, and to bring courage back into our young people and society. Theme(56)_____________ with young people 30 years ago, those are less courageous.The behavior of young people today*They generally show (57) ___________for elders and other people. *They take for granted whatever they have or receive. *Many of them are too (58) ____________ on their parents or other relatives to get them through life. (59)____________*They are not (60) ________ of the basics of respecting others. *They are not taught to work hard to (61)__________ their dreams *They don’t have the (62) _______ to make wise decisions and overcome difficulties independently. *They tend to expect others, such as their parents or siblings, to help them out when they are in (63)___________. Tips*Never (64) ____________ them; only help them when necessary. *Teach them the skills they need to make basic life decisions by themselves. Conclusion It’s time we went back to older values and ideas, and (65)___________ courage back into our young people and society. 单词拼写 (10分。

One effective way of destroying happiness is to look at something and focus on even the smallest fault. It’s like looking at the tiled (铺瓦的) ceiling and concentrating on the space where one tile is 1 . Once I heard a bald man said, “Whenever I enter a room, all I see is hair.” Once you’ve2 what your missing tile is, explore whether acquiring it will3 make you happy. Then do one of the three things: get it, replace it with a different4 , or forget about it and5 the tiles in your life that are not missing.We all know people who have had a relatively 6 life, yet are essentially unhappy, while people who have suffered a great deal generally remain happy. The first 7 is gratitude. All happy people are grateful. Ungrateful people cannot be happy. We tend to think that being unhappy leads people to 8 , but it’s truer to say that complaining leads to people becoming unhappy. The second secret is awareness. We should 9 that happiness is a byproduct (副产品) of something else. The most obvious 10 are those pursuits ( 追求) that give our lives purpose---anything from studying insects to playing baseball. The more passions we have, the more happiness we are 11 to experience. Finally, the belief that something permanent goes beyond us and that our12 has some larger meaning can help us to feel happier.

She said, "I don't think I know you, but you must be hungry. Please come in and have something to eat."? "Is the man of the house home?” they asked. "No", she replied, "He's out."?"Then we cannot come in", they replied. In the evening when her husband came home, she told him what had happened. "Go to tell them I am home and invite them in!" The woman went out and invited the men in. "We do not go into a house together," they replied. "Why is that?" she asked.? One of the old men explained that their names were Wealth(财富), Success and Love. Then he added, "Now go in and discuss with your husband which one of us you want in your home."? The woman went in and told her husband what was said. Her husband was overjoyed and he suggested inviting Wealth to fill their home with wealth. And his wife wanted to invite Success; but their daughter-in-law suggested they should invite Love so that their home would be filled with love. At last the husband said to his wife. "Go out and invite Love to be our guest." The woman went out and asked the three old men, "Which one of you is Love? Please come in and be our guest."? Love got up and started walking toward the house.? The other two also got up and followed him. Surprised, the lady asked Wealth and Success: "I only invited Love, Why are you coming in?"? The old men replied together: "If you had invited Wealth or Success, the other two of us would have stayed out, but since you invited Love, wherever he goes, we go with him. Wherever there is Love, there is also Wealth and Success!"? 41. The best title for this passage would be __________. A. A Woman and Three MenB. Wealth, Success and Love?C.

The three old men are brothers and they can’t be separated. B. The husband will refuse them in. C. The wife will be scolded by the husband. D. If a person has love, he will own everything. B About 21,000 young people in 17 American states do not go to classes in school buildings. Instead, they receive their school education by working at home on computers. The Center for Education Reform says the United States has 67 public “cyberschools,”(网上学校)and that is about twice as many as two years ago. The money for students to go to a cyberschool comes from the governments of the states where they live. Some educators say cyberschools receive money that should support traditional public schools. They also say it is difficult to know if students are learning well. Other educators praise this new form of education for letting students work at their own speed. These people say cyberschools help students who were unhappy or unsuccessful in traditional schools. They say learning at home by computer ends long bus rides for children who live far from school Whatever the judgment of cyberschools, they are getting more and more popular. For example, a new cybershool called Common-wealth Connections Academy will take in students this fall. It will serve children in the state of Pennsylvania from ages five through thirteen. Children get free equipment for their online education. This includes a computer, a printer, booksand technical(技术的) services. Parents and students talk with teachers by telephone or by sending emails through their computer when necessary. Students at cyberschools usually do not know one another. But 56 such students who finished studies at Western Pennsylvania Cyber Charter School recently met for the first time. They were guests honor at their graduation. 45. What do we know from the text about students of a cyberschool? A. They have to take long bus rides to school. B. They study at home rather than in classrooms. C. They receive money from traditional public schools. D. They do well in traditional school program. 46. What is a problem with cyberschools? A. Their equipment costs a lot of money. B. They get little support from the state government. C. It is hard to know students’ progress in learning. D. The students find it hard to make friends. 47. Cyberschools are getting popular because ________. A. they are less expensive for students B. their students can work at their own speed C. their graduates are more successful in society D. they serve students in a wider age range(范围) 48. We can infer that the author of the text is ________. A. unprejudiced(无偏见的) in his description(描述) of cyberschools B. excited about the future of cyberschools C. doubtful about the quality of cyberschools D. disappointed at the development of cyberschools C Books for Children Fleabag and the Ring's End Beth Webb More stories of Fleabag, the talking cat—star of this wonderful set of 3 books.

If your child wants to read stories of animals, whose book will be your choice?A. Pat Alexander.B. Beth Webb.C. Lois Rock.D. Elizabeth Goudge. D Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you! Parapsychologists (灵学家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense” really exists, Robert Baker, a psychologist (心理学家) at the University of Kentucky, did two experiments. In the first one, Baker sat behind unknowing people in public places and stared at the backs oftheir heads for 5 to 15 minutes. The subjects(受试者)were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he wassitting behind them during those periods. Later, when he questioned the subjects, almostll of them said they had no sens e that someone was staring at them. For the second experiment, Baker told the subjects that they would be stared at from time to time from behind in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t. Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.” 52. The aim of the two experiments is to_______. A. explain when people can have a sixth sense B. show how people act while being watched in the lab C. study whether humans can sense when they are stared at D. prove why humans have a sixth sense 53. The underlined word “outcome” in the last paragraph most probably means_______.A. value?B. result?C. performance?D. connection 54. In the second experiment, the subjects _________. A. could tell when they were stared at and when they werene a ’t. B. could tell when they were stared at but couldn’t tell when they weren’t. C. couldn’t tell when they were stared at but could tell when they weren’t. D. couldn’t tell when they were stared at or when they weren’t. 55. What can be learned from the passage? A. People are born with a sixth sense. B. The experiments support parapsychologists’ idea. C. The subjects do not have a sixth sense in the experiments. D. People have a sixth sense in all places.

All he had left was $10. He decided to use it to buy food and then wait for death as he was too proud to go begging.. He was frustrated as he could find no job, and nobody was ready to help him.He bought food and as he sat down to eat, an old man and two little children came along and asked him to help them with food as they had not eaten for almost a week. He looked at them. They were so lean that he could see their bones coming out. Their eyes had gone into the socket. With the last bit of compassion he had, he gave them the food. The old man and children prayed that God would bless and prosper him and then gave him a very old coin. The young graduate said to them 'you need the prayer more than I do'.With no money, no job, no food, the young graduate went under the bridge to rest and wait for death. As he was about to sleep, he saw an old newspaper on the ground. He picked it up, and suddenly he saw an advertisement for people with old coins to come to a certain address.He decided to go there with the old coin the old man gave him. On getting to the place, he gave the proprietor the coin. The proprietor screamed, brought out a big book and showed the young graduate a photograph. This same old coin was worth 3 million dollars. The young graduate was overjoyed as the proprietor gave him a bank draft for 3 million dollars within an hour. He collected the Bank Draft and went in search of the old man and little children.By the time he got to where he left them eating, they had gone. He asked the owner of the canteen if he knew them. He said no but they left a note for you. He quickly opened the note thinking it would lead him to find them.This is what the note said: 'You gave us your all and we have rewarded you back with the coin,'卷(七)南京盐城卷参考答案听力: 1-5 CACAB 6-10 ABBCA 11-15BCBAC 16-20CBACA单项选择:21-25 CBDAC 26-30 ADBBA 31-35 BDCAC完型填空:36-40DACBC 41-45 DDBCA 46-50 BADCB 51 55 CBAAD阅读: 56-60 CABDC 61-65 ABDCA 66 70 DBCAD71. definition 72. expression 73 release 74. senses 75 look / appearance / outside 76. researching / studying 77. controversial 78. writings 79. mostly / mainly80. significance / importance【写作指导】本文是图画作文,一般分为三段,第一段描述图画内容,第二段与图画相关的一些现象,第三段发表自己的观点。
