第一套题A Good LessonAfter living in Europe for seven years, my parents decided that my family would move to the United States. We all looked forward to this. What would people think us?For me, I hoped to be the hero of the class.I was not disappointed. All my classmates admired my experience, and I quickly became well known as“the French guy.”I was very popular for a time. However, I was not interested in many things my classmates did, and it was hard for me to connect with them. I enjoyed listening to classical music, never watched TV, and almost never watched movies.I did not have a common background with my friends because I grew up in Europe. I had few friends, and fewer friends. When I look back now, I realize I was a bit of an idiot to many people around me. I kept talking proudly about my experience. And I thought myself better than those around me because I lived in Europe but they didn’t.I had decided I wanted better friends when my parents said that we were going to move again! I saw this as a perfect chance to get better friends, where people did not know of my unkind past.When we moved to California, I did not show off as I had done for five years. I did not tell everyone that I lived in Europe. I still listened to classical music, but I just kept my music to myself. Sure enough, I found that people like someone who is not typical but does not boast about it.Nothing can replace good friends, and if I had to control my temper and pride, it was well worth it.11. When I first moved to the US, I was very popular because of my____.A. good appearanceB. outstanding talentsC. French accentD. overseas experiences12.

When we moved to California, I stopped____.A. boasting about my experienceB. talking about people around meC. enjoying the classical music aloneD. making friends with my classmates15. The writer would probably agree that____.A. good friends like the same kind of musicB. friends are more important than anything elseC. similar background is the key to friendshipD. a good friend never loses his/her temper第二套试题Kindness of StrangersAt the store where I worked, I noticed a young boy of about ten shopping alone with his school list. He placed everything in his basket and went to the checkout.The young shop assistant told him the total price,$37.60. The boy was instantly disappointed and said he had only been given $20. He took out one thing at a time until he got down to his $20. With eyes full of tears, he asked if he could phone his mum to pick him up. When he got through, it appeared that even this was inconvenient for his mother.He bit hard on his lip to stop the tears and walked outside to wait on the bench in front of the shop. This was all too much for the young assistant who had served him and she said,“I wish I could afford to pay for the rest of his things.” One of the other girls said she had a few dollars. Then two others said they could help as well.These four young girls pooled their money and found that they had more than enough money for the boy’s extra purchases. So they upgraded his pens and pencils to top-quality ones, then took the bag out to the boy on the seat. His young face changed from sadness to the most beautiful smile. His mother arrived much later to pick him up. Instead of running to the car, he ran back into the store and called out,“Thank you!”I was so proud of my team that day. They did something wonderful for that boy and also found the pleasure of giving was as great as receiving.11.The boy went to the store to .A. buy a basketB. ask for helpC. shop for schoolD. make a phone call12. At the checkout, the boy found that he .A. did not have enough moneyB. did not have his money on himC. forgot to ask his mum for moneyD. had lost his money in the store13.

The boy ran back into the store to___________.A. do extra shoppingB. express his thanksC. return the moneyD. take his bag out第三套Talk to Your Kids about Their Eating Habits CarefullyWeight is never an easy subject. It can be risky for parents to raise the issueof eating habits and weight with their kids.“No kid ever lost weight because his mother told him he was fat,” a friend told me when I was worried about my son’s weight.It turns out she was right, according to a new study. The study was directed by Dr. Berge at University of Minnesota. She found that kids whose parents discussed eating in a healthy way were less likely to have eating problems. But 64% of the kids whose parents focused on their weight turned to unhealthy eating behaviors. Some kids went on extreme diets, and others even ate no food. So eating disorders were caused. Things were worse when fathers joined in the discussions with their daughters and focused on weight. “Fathers should never comment on their daughters’ weight,” says Berge. Instead, she suggests, fathers should focus on their daughters' interests. That can help them feel loved and confident enough to work on their weight issues.How should parents talk to kids about. eating behaviors? According to Berge, they should avoid focusing on how much their kids weigh. They should talk to them about being healthy. Don't compare them with others. Ideally, both parents should share the responsibility. If that' s not possible, choose the parent whose words cause the least amount of stress and who demonstrates healthy eating.11. The writer' s friend advised her not to .A. worried about her son's weightB. take the risk of gaining weightC. change her own eating habitsD. talk to her son about his weight12. The study found that some kids had fewer eating problems because they ________.A. learned to eat healthilyB. took part in the studyC. focused on their weightD. believed the scientists13. When told about their fatness, some kids _____________.A. felt helplessB. became angryC. began to eat no foodD. refused to take any advice14. If a father focuses on his daughter' s interests, she will feel ____________.A. amusedB. encouragedC. surprisedD. challenged15. When taking to their kids about eating behaviors, parents should ______________.A. focus on being healthyB. use short and simple wordsC. respect their kids' viewsD. compare their kids with others第四套Just Introduce YourselfIt’s so easy to walk into your first job and feel like a stranger in a strange land. But you don’t have to stay that way, and you shouldn’t.You have to remind yourself to kick your shyness away and introduce yourself. Just a handshake will do. Ask the supervisor who hired you to introduce you around a bit. That’s the best way to make contacts. Then you’ll know what to do and say when you meet these people again.Don’t do what my friend Sue did at her first job at Entertainment Weekly. “That is one of my biggest regrets: I hardly talked to anyone at all when I was there. I was scared and just thought people would talk to me first. For a long time, I was hung up on the thought that if someone was older, I respected them automatically. And even if someone started on Monday, and I started Tuesday, I just felt they had more experience. In the area I worked for four months, I hardly spoke to these people,” she said.“Of course, now I realize that was the most stupid thing. If I could do that again, I’d remember that it’s so important not to feel shy about introducing yourself. It’s not like you have to be very bold, ready to take over the place. Just introduce yourself and ask if there is anything you can do for them. That breaks the ice.”Sun believes that if she had introduced herself around a bit, there would be just no telling what other opportunities or what other acquaintances she might have now.Not that she regrets where she is now at all. But had she talked to more people at her first job, “maybe it would have helped me get somewhere sooner,” she said.11. How do people usually feel when meeting people are their first job?A . Shy. B. Puzzled. C. Curious. D. Excited.12. When Sue stated her first job, she___ ____.A. introduced herself aroundB. asked her supervisor for helpC. shook hands with colleaguesD. waited for others to talk to her13.”I was hung up on the thought” in Paragraph 3 probably means”I__________”.A. believedB. guessedC. learnedD. admitted14. What did Sue suggest we do at our first job?A. Seize every possible opportunity.B. Get ready to take over the place.C. Make active contacts with others.D. Stay humble before the older staff.15. In talking about her first job experience, Sue expressed a sense of ___________.A. reliefB. regretC. failureD. longing第五套Living in Brazil (巴西)and SwitzerlandMoving to a different city may seem difficult. You have to change schools and get used to your new home. But you can always go back to that city to visit. When you move to another country, things are different. However, difficult as it may be, theexperience can be rewarding.My dad, a Brazilian, is really funny and can make friends quickly. My mom, a Swiss, is usually quiet and a bit shy. She likes to be organized. But my dad never makes plans. She enjoys staying home, but my dad always wants to go out. Swiss and Brazilian一what a mix!After my parents got married, they moved to Switzerland. There they had my brother and me. When I was two, we moved to Brazil. During my childhood we visited Switzerland every year.Many people ask me where I prefer to live: Brazil or Switzerland. It's really hard to answer because I love both countries. Brazil is a big country with many states and people. There are multiple dialects and many types of foods. People here have beautiful smiles and are always happy, even if they are poor. In the south the climate is cool, but in the north It's hot and humid.Switzerland, on the other hand, is small but beautiful and clean. There are four languages in that tiny country. People there are very different from Brazilians: they are wealthy, independent, and organized. The food is delicious, and of course, the famous Swiss chocolate is great, and the climate is dry and cool.I love both countries. In Switzerland, it's pleasant, calm, and peaceful everywhere. I enjoyed my stay there very much. But now I am happy here in Brazil. I feel excited and at home.11. The author's parents___.A. share similar interestsB. have different jobsC. have different personalitiesD. enjoy reading books12.When the author was a child, the family used to___.A. have many good friendsB. move between the two countriesC. speak two dialectsD. visit Brazil from time to time13.The author thinks Brazilians are___.A. organizedB. independentC. indifferentD. optimistic14. According to the text, Switzerland___.A is famous for its chocolate B. has many big citiesC. has a lot in common with BrazilD. is hot and humid15. According to the author, living in two different cultures is a(n)___.A. appealing ideaB. difficult decisionC. expensive choiceD. pleasant experience第六套Those Who Ride on Two WheelsIn the United States there are six million tennis players and twelve million golfers. These figures would not surprise most people. But many would be surprised to learn that twenty million Americans ride motorcycles (摩托车).Few people realize thatmotorcycling is fast becoming one of America’s most popular sports.According to the Cycle News, many kinds of people enjoy motorcycling. They include black people and white people, businessmen, professionals, and blue-collar workers. Among them, about 55% are businessmen, 3% are in the professions and 9% in government service.Such information is offered by the Cycle News in the hope of improving the general public’s impression of the sport. The public has tended to believe that all motorcyclists are wild and lawless young men.There are several things about motorcycling that the average citizen dislikes. A motorcyclist’s appearance has something to do with this dislike. Motorcyclists often look dirty; in fact, they are dirty. On the road, there is little to protect them from mud. For practical reasons, they often dress in old clothing which looks much less respectable than the clothing of people who ride in cars. For the same reason, motorcyclists usually wear dark colors. Perhaps this helps to explain why they are sometimes suspected of having bad natures.Probably motorcycles themselves also produce anger and fear. They are noisy,though some trucks are even noisier. But trucks are acceptable because they perform a needed service. Motorcycles, on the other hand, make an uncomfortable noise just to give their riders pleasure. Roaring along quiet streets, they wake sleeping families and make babies cry.Yet, as motorcycling becomes more and more common, it will be interesting to see how people in general feel about the sport. Perhaps it will someday become as‘respectable’’ as tennis or golf.11. According to the text, more and more Americans like___.A.playing tennisB. playing golfC. motorcyclingD. car-racing12.According to the Cycle News,over half of the motorcyclists are _____•A. black peopleB. white peopleC. businessmen .D. professionals13.The Cycle News wants to_________A. make motorcyclists lawful citizensB. improve the image of motorcyclingC. persuade people to buy motorcyclesD. raise the status of blue-collar workers14.Motorcyclists usually wear dark colors because_________.A. they want to be respectableB.they want to be impressiveC.the colors look differentD.the colors suit their sport15. Some people dislike the motorcycle because it is___________.A.noisyB. heavyC.costlyD. illegal第七套It is estimated that there are more than 8 million restaurants in the world today. So it might surprise you to learn that restaurants as we know have only existed for a few centuries. Before 1765, there were no restaurants. There was nowhere :in which a server brought you food and drink that you chose from a menu In fact, there were no menus anywhere.There were places where travelers could eat centuries before that. The countryside was full of inns that would serve food. And there were bars where one could get a drink. The rich could also eat meals supplied by private cooks.But therewas nothing that could be called a “restaurant”.A Frenchman changed that. In 1765, he opened a place in Paris that sold soups. On his sign, he used the ten “restaurants” to describe what he was selling. Soups were considered “restorative”, so he called them “restaurants”.Finally, people started buying his soups even when not ill. And as time went on,people began to use the term “restaurant” to refer to the place where soup was sold rather than the soup itself. More “restaurants” opened up in France, and people began to buy soups more regularly.Then, restaurants in Paris began to serve food other than soups. In the 1780s,enus started to appear. By the 1800s, there were many types of restaurants, and the restaurant concept was spread throughout the British Empire.A slow start gave way to rapid growth. Cities and towns around the world are filled with restaurants today. It is estimated that there are l.6 million restaurants in Europe. In America, there are nearly a half million restaurants. Today, diners have millions of choices.11. Before 1765, travelers could have meals at a(n) _A.barB. innC. restaurantD. Canteen12. The first “restaurant” only servedA.soupsB.dessertsC.drinksD.fruits13. The word “restorative” (Line 3, Para. 3) most probably meansA. having a special flavorB. making you happierC. having a pleasant smellD. making you healthier14. The restaurant concept started inA. AmericaB. BritainC. Germany15. The best title for this text isA. Definition of RestaurantB. Importance of RestaurantC. Origin of RestaurantD. Types of Restaurant第八套Dog TrainingDog training is a must for all dogs. It is more than just telling your dog to stop doing what he’s doing; it is the process of teaching a dog to exhibit certain desired behaviors in specific circumstances. Proper dog training is not a “quick一it is an ongoing process.Dog training also involves teaching the owner. Going through dog training is something that every dog owner should do. It is like going to school over again. It is all about communication, and you need to learn to communicate with your dog.Training your dog to ”sit” is probably the first thing you will train your dog to do. When you want your dog to sit, hold a treat above his head and say “sit”. As the dog sits, say “sit” again and then immediately give him the treat. Your dog should drop into a “sit” position in order to reach the food.Teaching your dog to fetch promotes bonding. To do this, first throw a ball, and give the command “fetch”. As he starts to run towards it, yell “fetch” again. Instead of a ball, you may use the object your dog loves most. Do not play fetch with heavy items or sticks, however, as this can dam age the dog’s teeth or injure the dog.A well-trained dog should remain where his owner commands, so “stay” is an important command in dog training as well. Since it is more involved, that will be the subject of another article.Dog training is a very physical activity, so be prepared to be tired. And dog training is never without risk of injury, especially with more aggressive dogs. Onemajor mistake many dog owners make is to think that the dog training is over. Training your dog continues throughout your dog's life.11.What docs the author say about dog training?A.It requires professional guidance.B. It is necessary for every dog.C.It gives dogs good exercise.D. It is an easy job for trainers.12.What is the most important thing for dog trainers to do?A. Learn to communicate with dogs.B.

Teach dogs desired behaviors.13.Dog trainers usually train their dogs first to ( ).A. jumpB. slayC. fetchD.sit14.To train dogs to fetch,trainers often start with a ( ).A. stickB. ballC. treatD. trick15.Many dog owners tend to think that dog training( ).A. can be dangerousB. costs much moneyC lakes a short time D. can be very tiring第九套Whenever people from Scotland live in foreign countries, they are always asked:"Is Scotland that place where men wear skirts? "The short answer is yes, but there is more about the myths of Scottish "skirts."The“skirt” that Scotsmen(苏格兰男子) sometimes wear is called a kilt..It is part of the traditional dress of Scotland. The kilt is clearly very famous across the world. It seems that everybody has heard of it, and that most people have seen a picture of a man wearing onePeople's knowledge and ideas about Scotsmen wearing these funny kilts come from films and television. Every time people from other countries ask about the kilt, they mention Mel Gibson's film, Brave heart. In many countries, there are television programs about Scotland. These programs always include information or images of men in kilts.Of course, in Scotland, you will often see the kilt. The reality is, though, that you will most commonly see it in tourist areas. The main streets and tourist areas of Scotland always have a Scotsman wearing a kilt and all tourist shops in the country sell kilts in different colors.But kilts are not something that Scottish people see every day. Kilts are for special occasions, such as weddings, funerals and other big and important events.Scotsmen do not put on their kilt just to buy a bottle of milk and a loaf of bread at the local supermarketThe reason for this may be that kilts are very expensive. When a man wears a kilt, he normally wears it with a special shirt jacket, socks and shoes. This is obviously not cheap. In fact, an average kilt outfit(全套服装) costs around£500.11. According to the text, ScotsmenA. like foreign cultureB. sometimes wear kiltsC. enjoy talking about kiltsD. often visit foreign countries12.

This text is mainly about theA. history of kiltsB. production of kiltsC. myths of kiltsD. styles of kilts第十套Christmas GiftMary didn't know what to send to her grandparents for Christmas. It was always hard to choose a good Christmas present for them. They didn't need much, and it was hard for her to be creative every year.One year, she sent them a big wooden elephant. It sat on the counter for a year, but then it disappeared, probably into a closet somewhere. Another year, she made handmade soaps with nice smells, but they probably weren't any better than store-bought soaps. Last year, she sent lots of nice pictures of herself in frames, but grandparents 'house was small, and they couldn't hang up very many.This year, she decided on fruit. She lived where it was warm and there was lots of nice fruit. Her grandparents lived up north, where it was colder and they couldn't get fresh fruit all year ,or at least not oranges and grapefruit. Fresh fruit was healthy for her grandparents, too.Mary went to a fruit store and sampled the red oranges. She really liked them and bought a kilogram. Then she tried three kinds of grapefruit. The white ones were sour. The star grapefruit were interesting, but the dark red grapefruit were great. So she got a kilogram.Mary carefully packed the fruit in a box to keep them safe and dry in case one got smashed and its juice got everywhere. Then she wrote the address on the box and mailed it from the store.
