ADear Alcohol,You've been around forever. I can remember all the pain you've caused for me.Do you remember the night you almost took my father's life? I do. He loves you. Sometimes I think he loves you more than he loves me. He's addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn't the only one hurt by you that night.Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. "I'm so embarrassed," they said as I held their hair back so that they could vomit . "I'm sorry," they said when I called taxies for them, walking them out and paying the driver in advance. "This won't happen again," they said as they were sent to the hospital to have their stomachs pumped. Two 15-year-old girls slept in hospital beds that night thanks to you.Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn't realize her brother was in the midst of it all. She never saw him again. And it's all your fault.I wish you'd walk out of my life forever. I don't want anything to do with you. Look at all the painyou've caused. Sure, you've made people happy too from time to time. But the damage you've caused in the lives of millions is inexcusable. Stop luring (引诱) in the people I love. Stop hurting me, please.Sincerely,Anonymous24. What is the author's purpose in writing to alcohol?A. To introduce Mr. Alcohol to the readers.B. To describe the harm alcohol did to his family.C.

The underlined phrase "were intrigued by" is closest in meaning to ______.A. were familiar withB. were int1`BAlmost five years ago, I announced to my loved ones I was to become a Mrs. Naturally. I then began to wonder about the perfect wedding dress, hoping that it would fit me. Even at the age of 23, I had gone through my share of dieting.I am an emotional eater and I knew that at 5 feet 5 inches tall and 180 pounds, I wasn’t at my healthiest. My mother had been doing Weight Watchers for some time and was rapidly seeing results without starving herself. She shared her books with me and explained the program: estimate your daily target based on your weight and other factors, write down everything you eat and move! The longer I stuck to it the more I noticed a difference in the way I enjoyed food. I soon began to like eating fruits and vegetables for snacks instead of chocolate bars and chips. My mother and I went on walks together and kept each other in check. Unsurprisingly, I lost twenty pounds soon and looked amazing in my wedding dress.I buy healthy foods, replace ice cream and faithfully keep a food journal. I exercised and take evening walks. Because I have a hard time reaching for something healthy by myself, I bought a Weight Watchers cookbook and use it to prepare our meals. I use small plates and bowls to trick myself into believing there is more food than the serving size.It’s been hard to discipline myself not to eat badly. But when I find myself having a desire for strawberries instead of chocolate, I know it’s all worthwhile.21．The author successfully lost twenty pounds ____________．A．by walking and eating less every day B．by only eating fruits and vegetablesC．under her doctor’s direction D．with the help of her mother22．What is the third paragraph mainly about?A．How to prepare healthy food．B．The ways of eating less food．C．The role exercise plays in keeping fit．D．What the author does to keep healthy．23．We know from the last paragraph that the author ____________．A．likes strawberries mostB．has formed healthy eating habitsC．can’t resist chocolateD．finds keeping a healthy diet easyCJust three days after hitting the screen across China, the Chinese animation (动画) film “Monkey King: Hero is Back” aroused enthusiasm among audience and ticket sales have exceeded（超过）100 million yuan ($16.11 million).Web celebrities and many fans even posted topics about the film on China’s Twitter-like Weibo, at which heated discussion are sparked.“Monkey King: Hero is Back” is based on the household legend of the Monkey King, but tell s a not-so familiar story. However, it’s still a Chinese style heroic legend and an exciting adventure against evil and darkness in troubled times, according to Lu Wei, the producer.“Monkey King is China’s super hero. It is so popular among Chinese audien ce because they long for and cherish our own superhero,” said Tian Xiaopeng, the director.Some media also put on a lot of comments from foreigners.“He’s never dead, he’s just fallen asleep. We all need a hero to look up to, to give us hope and courage when it is needed. We grew up listening to his tales, his great adventures and heroic deeds. What makes a true hero is not just helping people when one has the power, but having the courage to stand up against the evil even without power. And this is what the film is about. When the hero loses his power and armor, when he is nothing more than an ordinary monkey, what would he do to protect the one he loves? This is also about a group of Chinese dream chasers trying to keep the beacon of hope lit even though being in the most unfavorable situations” from Tumblr.“Though the film was injected with a little bit of Hollywood, its bold and creative story has attracted several Chinese cinema aficionados.” from Yibada.One netizen posted after watching the film: “The film sets a new high-bar for the domestic animation film, when I walked out of the theater, I was crying.”12. According to the director’s opinion, the film is so popular among Chinese audience because_______.A. Chinese audience long for and cherish his own superheroB. the film is based on the household legend of the Monkey KingC. the Chinese need a hero to look up to, to give them hope and courageD. the film was injected with a little bit of Hollywood13. According to the passage, it can be inferred that _________.A. the film is still a Chinese style heroic legendB. the film is well-receivedC. the film tells us the fact that what makes a true hero is to help people when one has the powerD. the film only aroused enthusiasm among Chinese audience14. After watching the film, the netizen mentioned in the last paragraph was _________.A. very sadB. deeply moved C .very crazy D. deeply gloomy15. Why does the writer mention Weibo, Tumblr and Yibada? Because he wants to __________.A. persuade more readers to visit themB. tell readers some information about themC. make them better known to readersD. provide some evidence for readersDDo you sometimes argue about what seems to you to be a simple fact? Do you argue whether it’s cold outdoors or whether the car in front of you is going faster than the speed limit?If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who f elt the elephant’s trunk said it was like a snake. The second who felt the elephant’s side said it was like a wall, while the third said it was like a spear as he touched the animal’s tusk(长牙). The fourth, who had hold of the elephant’s tail insisted that it was like a rope. The fifth man said it looked like a tree as he put his arm around one of the elephant’s legs.The sixth, who was tall and got hold of the elephant’s ears, said it was like a huge fan.Each man’s idea of the animal came from his own exper ience. So if someone disagrees with you about a “simple fact”, it’s often because his experience in the matter is different from yours.To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm（不冷不热的）water in the third. Now put your left hand in the ice water. Put your right hand in the hot water. After thirty seconds, put both hands in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it’s hot !24. What makes people think about simple facts differently ?A. The fact that simple facts differ from one anotherB.The fact that people have different experience in the same simple factC. The fact that people often disagree with one anotherD. The fact that it’s hard to make up one’s mind about simple facts25. The writer’s advice is _______________.A. We should never think about simple factsB. We should never judge something with a one-sided viewC. We should not agree about simple factsD. We must learn from the six blind men26. What do you think of the six blind man?A. They are the examples of those who look on things only from one side.B. They are skilled at exploring different things.C. They are all experts in studying elephant.D. They are the examples of those who always refuse to trust friends.27. After reading the last paragraph, we may think of __________.A. Newton’s lawB. Galileo’s theory of fal ling objectsC. Einstein’s theory of relativityD. Marx’s Theory On Capital (资本)第二节（七选五共5小题，每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

At the gathering, a man called Douglas was again and again talking about Lincoln's low position in life and saying that he first met Lincoln when Lincoln was a shop assistant at a village shop. Finally, he said, “And Mr. Lincoln was a very good shop assistant, too.”People burst into laughter, but they quieted down when Mr. Lincoln said calmly, “Gentleman, what Mr. Douglas has said is true. I did sell cotton, candles and cigars, and sometimes whisky. But I remember that in those days Mr. Douglas was one of my best buyers. I often stood on one side of the counter and sold whisky to Mr. Douglas on the other side, but the difference between us is：I have left my side of the counter, but Mr. Douglas still_sticks_to_his_as_firmly_as_ever.”25．The story took place at a ________.A. meetingB.restaurantC. concertD. gettogether26．Why was Mr. Douglas again and again talking about Lincoln's low position in life?A. Because he was friendly to Lincoln.B. Because Lincoln was an example to show that an American of low position in life can become President of the US.C.

He won it by telling of his low position in life in his early days.B. He won it by telling of his high position in life in his early days.C. He won it by saying Douglas was telling a lie.D. He won it by comparing his present position with Douglas'.28．The underlined sentence in the last paragraph means Douglas ________.A. is still talking about Lincoln's low position in lifeB. is still standing on the other side of the counterC. is still drinking a lot and has not changed a bitD. keeps on going to gatherings and talking a lotCThe history of civil engineering(土木工程) is a very important story in the development of civilization(文明)．Civil engineers began practising their profession four thousand years ago.What is left of their work is the proof that they were wise.These engineers of the ancient world built entire cities.They designed systems of pipes which supplied fresh water.They built water pipelines for farmlands as well as bridges of great length.The relics of their buildings tell us much about the work of early engineers.Consider the pyramids of Egypt.They are evidence that some of the earliest engineers had great scientific ability.There is also evidence that those engineers could make lasting work of art and design.Although they lived thousands of years ago，the Eygptian engineers used very exact measurements.The base of the largest pyramid—the Great Pyramid near Giza—comes to within inches of being a perfect square.The pyramid is perfectly placed.Each corner points toward the exact directions of north，south，east and west.The inside of the pyramid is filled with complicated(复杂的) passages and tunnels.These lead to different rooms inside the pyramid.Many of these passages are of great length and height.The engineers of Egypt did more than design the pyramids.They also set up methods of moving and shaping the building materials.These materials were very heavy.They had to be brought from miles away and sometimes lifted several hundred feet.During the work the engineers commanded thousands of workers.The pyramids remain as evidence of the abilities of the ancient Egyptian engineers.1．Forty centuries ago ________.A．there appeared civil engineers by professionB．people began practising engineering in order to become professional engineers C．civil engineers began putting their knowledge into practiceD．civil engineers got more involved in their profession2．The civil engineers of ancient times were wise enough to build entire cities，including ________.A．systems of pipes，bridges and machineryB．pipeline systems，bridges and farmlandsC．water supply systems，bridges and pipelinesD．water supply systems，bridges and stadiums3．From the passage we know that ________.A．building materials were broken into small piecesB．there were no requirements for the size and shape of building materials C．Egyptian engineers were not concerned with the size and shape of building materials D．building materials were processed(加工) to meet certain requirements4．The passage can be best titled ________.A．Evidence of Human CivilizationB．Early Civil EngineersC．Ancient Architecture(建筑)D．Development of Civil EngineeringDOur “Mommy and Me” time began two years ago.My nextdoor neighbor and fellow mother，Christie，and I were out in our front yards，watching seven children of age 6 and under ride their bikes up and down.“I wish I could take one of my children out alone，”said Christie.Then we worked out a plan：When Christie takes one of her children out，I’ll watch her other three.And when she watches two of mine，I’ll take someone out.The children were extremely quick to accept the idea of “Mommy and Me” time.Christie’s daughter，McKenzie，went first.When she returned，the other children showered her with tons of questions.McKenzie was smiling broadly.Christie looked refreshed and happy.“She’s like a different child when there’s no one else around，” Christie shared with me quietly.With her mother all to herself，McKenzie didn’t have to make an effort to gain attention.Just as Christie had noticed changes in McKenzie，I also discovered something different in each of my children during our alone times.For example，I am always surprised when my daughter，who is seldom close to me，holds my hand frequently.My stuttering (口吃的) son，Tom，doesn’t stutter once during our act ivities since he doesn’t have to struggle for a chance to speak.And the other son，Sam，who’s always a follower when around other children shines as a leader during our times together.The “Mommy and Me” time allows us to be simply alone and away with each child—talking，sharing，and laughing，which has been the biggest gain.Every child deserves (应得到) to be an only child at least once in a while.68．What is the text mainly about?A．The experience of the only child being with mother.B．The advantage of spending time with one child at a time.C．The happy life of two families.D．The basic needs of children.69．Right after McKenzie came back，the other children were ________.A．happy B．curiousC．regretful D．friendly70．What does everyone gain in “Mommy and Me” time according to the passage? A．Every mother has more free time to do things they like.B．Every child has more chances to express and enjoy themselves.C．Every child can get rid of his or her stuttering.D．Both A and B.第二节（七选五共5小题，每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

AKatie was in big trouble．She was such a sweet kid; a third - grade teacher always dreamed of having a classroom filled with Katie’s she wa s never ever a discipline（纪律）problem．I just couldn't imagine why she had made her parents so angry．It seemed that Katie had been running up sizable charges in the lunchroom．Her parents explained that Katie brought a great homemade lunch each day, and there was no reason for her to buy school lunch．They assumed a sit - down with Katie would solve the problem, but failed．So they asked me to help them get to the bottom of this situation.So the next day, I asked Katie to my office．"Why are you charging lunches, Katie? What happened to your homemade lunch?" I asked．"I lose it," she responded．I leaned back in my chair and said, "I don't believe you, Katie．" She didn't care．"Is someone stealing your lunch, Katie?" I took a new track．"No．I just lose it," she said．Well, there was nothing else I could do．The problem was still unsolved the next week when I noticed a boy who was new to the school sitting alone at a lunch table．He always looked sad．I thought I would go and sit with him for a while．As I walked towards him, I noticed the lunch bag on the table．The name on the bag said " Katie " ．Now I understood and I talked to Katie．It seemed that the new boy never brought a lunch, and he wouldn't go to the lunch line for a free lunch．He had told Katie his secret and asked her not to tell anyone that his parents wanted him to get a free lunch at school．Katie asked me not to tell her parents, but I drove to her house that evening after I was sure that she was in bed．I had never seen parents so proud of their child．Katie didn't care that her parents and teacher were disappointed in her．But she cared about a little boy who was hungry and scared．Katie still buys lunch every day at school．And every day, as she heads out of the door, her mom hands her a delicious homemade lunch．46．What did the author think of Katie?A．She performed well at school．B．She was a girl filled with love．C．She often made trouble at school．D．She used to be a discipline problem．47．Why did Katie eat school lunch instead of her homemade lunch every day?A．She lost her homemade lunch．B．She had her homemade lunch stolen．C．She didn't like the taste of her homemade lunch．D．She gave her homemade lunch to a hungry boy．48．What was Katie's parents' reaction to the truth about the lunch?A．They were very angry．B．They were proud of Katie．C．They were disappointed．D．They were rather upset．49．What can we learn from the passage?A．Katie was informed that her parents had known her secret．B．Katie told the author the truth of her lunch during their first talk．C．Katie's secret of lunch was discovered by the author by accident．D．Katie stopped buying lunch at school after her secret was discovered．BMany of the world’s countries have reached or are approaching zero population growth (Z PG)．Nearly all such lands are economically well developed．They include much of Europe(including Russia)，the United States，Canada，Japan．and Australia．As the rate of natural increase(RNI)declines，two things happen．First，the population begins to decline if the loss is not balanced by immigration．Second，a country’s population ages because there are fewer births．Is achieving ZPG good or bad? What happens when a country’s population begins to drop? Many people，after all，believe that population decline is a good thing．But is it good for everyone? Does everyone agree?An aging population can create many problems．Senior citizens require more health care and medical attention．Rather than paying into retirement programs，they begin to draw from their pensions．In the US，the Social Security program，according to many experts，will be used up by 2018．It will pay out more money than it takes in．Additionally, a great number of jobs go begging in search of people willing or entry level positions that pay low wages．With an able to do them．Many of these jobs are aging population，who will fill them? At the other extreme，some positions require a large number of training and highly specialized skills．Who will fill these positions as retirees leave the workforce?The answer to the problem of declining and aging population is simple：increased migration．Today many people，particularly those from less developed countries，are migrating in search of employment．Many are willing to take jobs that cannot(or will not) be filled by the domestic population．Others are well educated and highly skilled．Both groups contribute to a country’s economy progress in many ways．Further, they add to the richness of a country’s culture．Of greatest importance，perhaps，is the fact that they have become absolutely necessary to the economy of many lands．As you can see，for many countries and for most immigrants，migration is a win—win situation．32．In the writer’s view，which of the following statements is TRUE?A．Not everyone agrees that achieving ZPG is absolutely good．B．Achieving ZPG is every country’s aim in spite of its side effects．C．Achieving ZPG is bad for senior citizens．D．Achieving ZPG is good for employment．33．According to the passage，the best way to solve the problem of declining and aging population is ．A．to improve the health care system B．to increase RNIC．to increase employment D．to increase migration34．The underlined words “the domestic population’’ can be replaced by．A．people within the country B．people from developing countriesC．people without a college education D．people living abroad35．The main idea of the last paragraph is .A．the advantages of increased migrationB．the problem of declining and aging populationC．how to increase migrationD．some ways to enrich a country’s cultureCNowadays many people are concerned about the problem of what to do with electronic waste such as old televisions, computers, radios, cellular telephones and other electronic equipment.Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers so they throw them in the trash.National Solid Waste Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans product is not unexpected.The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from landfills (垃圾填埋场) and create recycling programs. They can be torn apart and sorted for useable parts. Mike Fannon who runs the plant in Baltimore says, “There are lots of valuable metals that can be recovered and reused instead of just putting them in the landfill, and in certain components there are some materials that should not really be in the landfill. ”Fannon says nearly 20 percent of electronic waste is recycled nationwide. Thirteen years ago, it was only about 6 percent. Recycling rates continue to rise as more communities have banned electronics from landfills in order to keep e-waste poisons like lead (铅) and mercury (汞) out of garbage dumps.This year several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other states have also adopted bans on e-waste in landfills. Chaz Miller says more can be done to boost electronic waste recycling.“We can do much better,” noted Miller. “I think clearly our goal should be to do as well as we do recycling newspapers.”32. Which of the following does NOT belong to e-waste?A. Old televisions.B. Old computers.C. Old cell phones.D. Old newspapers.33. Why is e-waste banned from landfills in many states?A. Because it can not be recycled.B. Because the landfills are already full.C. Because it might damage the environment.D. Because it can be shipped to other countries.34. According to Mike Fannon, what might be the best way of dealing with e-waste?A. Recycling it.B. Selling it.C. Burying it.D. Breaking it.35. What can we learn from the passage?A. Chaz Miller works for EPA.B. Miller is optimistic about the future of e-waste.C. At present, less than 10 percent of e-waste is recycled.D. All states in the US have banned e-waste from landfills.DHave you ever heard the saying “All roads lead to Rome”? At one time, this was pretty much true. During the Roman Empire, lots of roads were built in order to move armies, send messages by courier (信使), and make trade easier.The network of Roman roads was begun in 312 BC. It was demanded that the roads be built strong so that they would not fall down. Roman soldiers, supervised (监督) by engineers, laid down the roads in a special pattern of layers. There were all together 4 layers, which was made of different materials, such as sand, rocks, stones and so on.Also, Roman roads were cambered(拱形). This means that they were built higher in the middle than on the edges, allowing rainwater to run off, which prevented flooding. We use the same technique in building roads today. The Romans also laid out roads over hills when necessary, setting them down in a zigzag (之字形的)pattern to make the road rise gradually.All Roman roads had milestones (里程碑), placed every thousand paces (a Roman mile). The milestonestold when the road was built, who was e mperor at the time, the road’s destination, how far the traveler was from the destination, and how many miles had been traveled since the beginning of the road. This information was a great help to travelers.Because of their excellence in construction, it really is no surprise that many parts of Roman road still exist today. These roadways are one of the most impressive achievements of the Roman Empire.21. The following description about Roman roads is true EXCEPT _____.A. Roman roads were built by the Roman soldiers directed by the engineersB. Roman roads could prevent flooding using the technique we don’t use todayC. Roman roads had milestones that were placed every Roman mileD .Roman roads still exist today as an impressive achievement of Roman Empire22. What information can you find on the milestones?A. The builders of the road.B. The materials used in building roads.C. The distance from one city.D. The time spent in building roads.23.

AThe world’s premier spelling bee ended Thursday in the U．S．for a second year in a row after an in-tense lo-round showdown between two young competitors to deal with some of the English language’s most obscure（生僻的）words.Vanya }hlvaShankar，13，and Gokul Venkatachalam，14，together raised the gold trophy（奖杯）in the 88th Scripps National Spelling Bee．Shivashankar，the sister of 2009 champion Kavya Shivashankar，initially gathered confidence as she went easily through such words as cytopoiesis，bouquetiere and thamakau．Venkatachalam，a basketball fan，also managed such tongue-twisters as poblacion，caudillismo and nixtamal．But as their eight fellow finalists failed one by one，the tension grew until they stood alone on stage·When Shivashankar，in the fourteenth round，correctly spelled scherenschnitte，the German 一derived（源自德语的）word for artistic paper cutting, official bee pronouncer Jacques Bailly, broke the news to．Venkatachalam . contest，Bailly said，was about to run out of words，and if Venkatachalam spelled his next word correctly，he and his rival（对手）would be declared joint winners一a repeat of last year’s surprise．The winning word came so easily to the eighth-grader from the branch St．Louis，Missouri suburb of Chesterfield that he skipped the bee contestant’s routine of asking for the word’s origin，meaning and usage in a sentence·“N一u一n一a一t一a一k，”the devoted LeBron James fan said，spelling the Inuit-derived word for an icy island as easily as if he was spelling d一。
2016年高考新课标卷寒假考练--英语试题(二)配答案
2016年高考新课标卷寒假考练--英语试题（二）配答案一、阅读部分：AMother and I start our new life in America. In the morning we travel together to work. Rising at the crack of dawn, I love the adventure of tiptoeing around in the dark living room where we sleep, whispering to each other so as not to wake Aunt Celia and Uncle Martin in the bedroom, then leaving the house soundlessly and making our way to the subway station in semidarkness. By the time we reach Kings Highway, the rising day throws a mysterious light on the empty and quiet avenue ordinarily crowded with human traffic, and on the shuttered(有百叶窗的) storefronts and fruit stands now cozily(舒适的) wrapped in layers of canvas(帆布). There is a sense of mystery---a sense of power---in being here before the rest of the world awakens…as if witnessing the beginning of time.We love traveling together on t he subway, Mother and I. It’s fun to observe our fellow subway riders, exchange jokes in Hungarian, play guessing games as to their identities, their ages, and their jobs and make bets as to where they’d be getting off.In a couple of weeks Mother becomes familiar with the train route, and she no longer allows me to accompany her.“But I’ll miss the fun of traveling together in the morning,” I protest.“So will I. But it comes at a sacrifice. In order to accompany me, you must rise an hour earlier, losing an hour’s sleep. You need that extra hour of sleep.” Mother is firm, and I have no choice but to comply and regretfully give up on our morning fun.“I hope you’ll have time to teach me English. Now that I have a job and travel alone on the subway, I’ll need to improve my vocabulary. I don’t want to depend on you every time I need to make a phone call in English, or want to take public transport.”“Okay, madam,” I agree in a happy, joking tone. “How about today? Let’s have our first lesson this evening!”Every evening I ask Mother a lot of questions about vocabulary and grammar, and indeed in a couple of weeks she learns enough to do marketing on her own and travel freely by subway.1. Which detail from the text shows that the author is excited about her life in America?A. Her resistance to the growing independence of her mother.B. Her acceptance of why she can no longer accompany her mother.C. Her description of rising early to ride the subway with her mother.D. Her discipline to work on language lessons every day with her mother2. Which of the following describes the author’s attitude towards her mother?A. Supportive.B. Disrespectful.C. Sympathetic.D. Angry.3. The text is most probably taken from ___________.A. a review of a bookB. a book about one’s life storyC. a travel magazineD. a handbook for foreigners.BWelcome to the world of multitasking---a place where the measure of a person is how many jobs they can perform at the same time. In fact, if experts are to be believed multitasking is a disastrous idea.One of the opponents(反对者) of multitasking is Dr. Clifford Nass, a professor at Stanford University. “People who multitask frequently are less able to pay attention; they are worse at managing their memory,” he said. In his opinion, the loss that we get with multitasking is harmless in some situations, for example, part of doing business in the digital world; but you can’t do serious work like writing, thinking or solving an importan t problem this way. You do worse even as you think you’re doing better. All the time the research points to a simple fact: the brain cannot cope. When you stop midway through composing a report to check an email, you force your brain to stop and regroup. It is like pressing the pause button during a movie, meaning the film takes longer to watch.And according to Dr. Nass, the problems extend beyond the brain. Young people who frequently multitask are not as socially and emotionally healthy as those who don’t. They just feel more emotionally satisfied and the feeling is so good and they are bound to desire it again. Todd Oppenheimer, a writer said, “We’ve become a very short-term society and don’t reward people for taking a lot of time on something.” He fears we may end up losing the next generation of great thinkers. “It’s really unfortunate because the long-term challenges of our world---environmental issues, financial issues---require people to think wisely about the long-term consequences of what they do. And it’s no coincidence that the kind of people who do think long-term don’t multitask.4. According to Dr. Nass, multitasking ________.A. contributes to memorizing various thingsB. may result in losing the next generation of great thinkersC. can be performed using digital toolsD. makes the performance emotionally affected only5. From the passage, we can tell ________.A. we mistakenly believe that we’re doing better by switching between tasksB. multitasking does harm to us in every areaC. for every task you add to your multitasking, you can finish your goal more quicklyD. the loss that we get with multitasking is harmless6. Which of the following is a multitasking addict?A. You watch from start to finish without distraction when playing a DVD.B. You have your office desk covered with paperwork from various unfinished projects.C. You feel that when you try to do too much at once, the result always suffers.D. You turn your cell phone to silence when you are out to dine with friends.7. The author mainly wants to tell us _________.A. it is more efficient to do things all in a mixed wayB. it takes longer for us to become a great thinkerC. we shouldn’t be lazy if we want to accomplish many tasksD. the less you switch, the better you doCAsk someone what they have done to help the environment recently and they will almost certainly mention recycling. Recycling in the home is very important of course. However, being forced to recycle often means we already have more material than we need. We are dealing with the results of that over-consumption in the greenest way possible, but it would be far better if we did not need to bring so much material home in the first place.The total amount of packaging increased by 12% between 1999 and 2005. It now makes up a third of a typical household’s waste in the UK. In many supermarkets nowadays food items are packaged twice with plastic and cardboard.Too much packaging is doing serious damage to the environment. The UK, for example, is running out of areas for burying this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect. Recycling helps, but the process itself uses energy. The solution is not to produce such items in the first place. Food waste is a serious problem, too. Too many supermarkets encourage customers to buy more than they need. However, a few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.But this is not just about supermarkets. It is about all of us. We have learned to associate packaging with quality. We have learned to think that something unpackaged is of poor quality. This is especially true of food. But it also applies to a wide range of consumer products, which often have far more packaging than necessary.There are signs of hope. As more of us recycle, we are beginning to realize just how much unnecessary material we are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.8. What does the underlined phrase “that over-consumption” refer to?A. Using too much packaging.B. Recycling too many wastes.C. Making more products than necessary.D. Having more material than is needed.9. The author uses figures in Para graph 2 to show.A. the tendency of cutting household wasteB. the increase of packaging recyclingC. the rapid growth of supermarketsD. the fact of packaging overuse10. According to the text, recycling.A. helps control the greenhouse effectB. means burning packaging for energyC. is the solution to gas shortageD. leads to a waste of land11. What can be inferred from Paragraph 4?A. Unpackaged products are of bad quality.B. Supermarkets care more about packaging.C. It is improper to judge quality by packaging.D. Other products are better packaged than food.DTeen Dating can be fun if you are aware of its pros and cons and are also aware of the ways to protect yourself. There are a couple of suggestions you would like to know before you are out for dating.Do not go out for dating with somebody whom you have seen only a few times and does not know much about him or her.Before leaving on a date, know the exact plans for the evening and make sure a parent or friend knows these plans and what time to expect you home. Let your date know that you are expected to call or tell that person when you get in.Similarly, if you leave a party with someone you do not know well, make sure you tell another person you are leaving and with whom. Ask a friend to call and make sure you arrive home safely.No matter how good the person appears to you, trust your inner instincts (直感). If a situation makes you uncomfortable, try to stay calm and think of a way to remove yourself from the situation without letting your date realize what is going on in your mind.Be aware of your decreased ability to react under the influence of alcohol or drugs and keep yourself in control when out for a date.Always stay firm, straightforward and clear in your relationships, thoughts,decisions and judgments. Never let a doubt come to your mind or face when out for dating. If you are firm and clear in your communication, your date will always be careful in dealing with you.You should think ahead about ways to be safe if you are in a dangerous or potentially dangerous relationship. Adults, like parents, teachers, counselors, can be trusted in such cases.12．Which of the following is forbidden when dating according to the passage?A．Going out for dating with a stranger.B．Knowing the plan for the evening.C．Telling your parents about the date.D．Telling the person you date that your parents know about the date.13．The underlined word “date ” in the third paragraph might mean ________.A．a time B．a plan C．a person D．a place14．If you feel uncomfortable, you should NOT _______.A．leave as soon as possible B．tell your date what you are thinkingC．stay calm D．trust yourself15．The best title for this passage might be .A．Be careful with your friends B．Never go out datingC．Safety measures for teen dating D．Dating out is always dangerous七选五Learn to Perfect Your Email Writing SkillsEmail is a double-edged sword．16．Here are some suggestions you need to know about writing emails in a professional setting.●Focus on the receiverBe clear about why you are emailing this person；briefly state it at the beginning. At the end of the email，also let them know that you’re available to be of help to them．●17If you foresee the information the receiver wants to know，you’ll remove the need for more emails．To be comprehensive，think of who，what，when，where，why，and how for each point you want to make．Use bullet points(项目符号)，lists，or separate short paragraphs to highlight information，and remember to include attachments mentioned in the body of the email．●Be accurate and specificThis tip applies to the body of the email and the subject line，which should never be blank．Include double-cheek dates，times，and names．Firstly，clarify time zones．18．●Be free of grammatical mistakesDon’t rely only on the spelling and autocorrect function．19．Then re-read your email．●Use the proper tone20．Are you being too demanding，inflexible，formal or informal? All of these tones can be unpleasant．Ensure a personal connection and show some humanity．Being too informal in your language might detract(贬低)from your authority．At the sametime，being too formal can make it difficult for the receiver to find a human or emotional connection with you．Finding the right tone can be, tough，but it is achievable．A．Don’t separate you and your receiver from the greater pictur eB．Be comprehensive，yet directC．It’s fast and convenient，but your words are permanent and may bother you D．Make sure the day of the week matches the calendar dateE．Consider context and world eventsF．Read the email by yourself to check for spelling, grammar, and word usage errors G．Put yourself in the shoes of the receiver and feel your tone22.

AThe ruins of Moore, Oklahoma, a town destructed for the fourth time in 14 years by a major tornado （龙卷风）, are a reminder that current building codes(规范) can’t do much to prevent property destruction and loss of life, especially when a powerful tornado cuts through town. But the total death number can be reduced when people take shelter in underground storm bunkers（碉堡）and hardened safe rooms.The tornado that carved a path of destruction through Moore took 24 lives. Its winds were clocked at 400 kilometers per hour. With only 15 minutes’ warning, residents fled town or took refuge（避难）in the firmest corners of their homes. The luckiest were able to climb into shelters or move to safe rooms.In Moore those rooms saved lives. But at two schools destroyed by Monday's tornado, no such shelter was available. Leslie Chapman Henderson is CEO of a non-profit group called the Federal Alliance for Safe Homes. She's an advocate for tornado safe rooms.“The safe room is an interior（内部）room of the home that has been reinforced（加固）and tested to withstand high wind. In fact, we’ve already heard of stories of survival of people who were in safe rooms, either above or below ground,” she said.Better storm forecasts give people more time to react. But they need someplace safe to go. Buildings can be built to resist strong winds, but not like those in the F-5 tornado that touched down in Moore. Chapman Henderson says even the building codes that do exist are not widely adopted or enforced.As its residents prepare to rebuild, Moore’s mayor is pushing for an order to make safe rooms compulsory in all new construction. Similar proposals were made following each of the previous tornado strikes, but none were adopted.25. According to Chapman Henderson, which of the following does she probably agree with?A. Building codes make a difference in preventing property destruction.B. If people take shelter in safe rooms, nobody will die.C. It is urgent to build tornado safe rooms.D. Safe rooms can be built only underground.26. What can we infer from the text?A. Moore has gone through tornado 4 times in total.B. Chapman Henderson is Moore’s mayor.C. Monday's tor nado took 24 lives at two schools.D. The Moore’s proposal might not be approved.27. The underlined word “withstand ” in paragraph 4 probably means________.A. opposeB. resistC. preventD. defeatBDo American children still learn handwriting in school? In the age of the keyboard, some people seem to think handwriting lessons are on the way out. 90% of teachers say they are required to teach handwriting. But studies have yet to answer the question of how well they are teaching it. One study published this year found that about three out of every four teachers say they are not prepared to teach handwriting. Some teachers are teaching handwriting by providing instruction for ten to fifteen minutes a day, and then other teachers who basically teach it for sixty to seventy minutes a day----which really is pretty much for handwriting.Many adults remember learning that way----by copying letters over and over again. Today’s thinking is that short periods of practice are better. Many experts also think handwriting should not be taught by itself. Instead, they say it should be used as a way to get students to express ideas. After all, that is why we write.Handwriting involves two skills. One is legibility, which means forming the letters so they can be read. The other is fluency －writing without having to think about it. Fluency continues to develop up until high school.But not everyone masters these skills. Teachers commonly report that about one fourth of their kids have poor handwriting. Some people might think handwriting is not important any more because of computers and voice recognition programs.But Steve Graham at Vanderbilt says word processing is rarely done in elementary school, especially in the early years. American children traditionally first learn to print, and then to write in cursive, whichconnects the letters. But guess what we learned from a spokeswoman for the College Board, which administers the SAT college admission test. More than 75% of students choose to print their essay on the test rather than write in cursive.１. We can infer from the first paragraph that ______.A. teachers spend little time in teaching handwriting.B. most teachers attach importance to teaching handwriting.C. handwriting teaching is not commonly required.D. most teachers are at a loss how to teach handwriting２. Which of the following about traditional handwriting in the USA is NOT true?A. The students are taught by practicing a long period.B. Printing is taught in preference to writing in cursive.C. Handwriting is taught for its own sake.D. Two skills get involved in handwriting.３. Some American people consider handwriting not important any more because ______.A. all the American children learn to print firstB. about 1/4 of the students choose to print their essay on the testC. it is unnecessary to use handwriting in the age of keyboardD. computers and voice recognition programs are widely used４. ______ may serve as the best title for the passage.A. Handwriting: fascinating in keyboard ageB. Right or wrong: the death of handwritingC. Two skills involved in handwritingD. Handwriting lessons on the way outCEveryone has some opinion about history, no matter how ill-informed. Walking through a parking lot in a university in Miami, I noticed a bumper sticker (车尾贴纸) that said, “Ruin a Liberal’s (自由派) Day—Recite Historical Fact!” But Marwick thinks this sort of opinion is just fine; it is unavoidable that weall feel a sense of ownership of history.History never stands still, as Marwick says at the beginning of The Nature of History, “The shape and content of history, too, vary according to the methods and materials available to different generations.” Marwick’s goal is to explain, in plain language, the changes in the way history is done up to th e present; one method is to connect history with advances in the physical sciences. Marwick examines a number of case studies toward the end of the book. He ends the book with a refreshing collection of aphorisms (格言) about history. History truly belongs to each and every man and we all belong to history; with the proper education, history can be made more accessible to everyone.Marwick relates how inventions and the physical sciences have driven historical changes. Dropping a ball in a vacuum will reveal the same properties (性质) each time the experiment is conducted, providing the conditions are the same. But historians obviously do not have the luxury of reproducing such conditions; historians view the past through the present which depends on invention and science.By looking at the changing nature of history, Marwick feels the study progressing. Although Marwick suspects some people would accuse a historian of creating job security with the endless views of the past, he insists it is imperative based on the philosophy, science, and new materials of the age. History, according to Marwick, must be for everyone and not remain locked behind the walls of academia.52. The author mentions the bumper sticker in order to ________.A. show his own opinion about historyB. introduce the readers to MarwickC. explain the freedom of understanding historyD. make the readers know about the argument between historians53. Which of the following best describes the statement “History never stands still”?A. Marwick explains the changes in the way history is done up to the present.B. Marwick connects history with advances in the physical sciences.C. He ends the book with a refreshing collection of aphorisms about history.D. The shape and content of history vary according to the methods and materials available.54. In paragraph 3, Marwick gives the example of dropping a ball in a vacuum to prove ________.A. the changeable nature of historyB. the difficulty of historical studyC. changeable ways of historical studyD. the difficulty of scientific study55. The text is intended to ________.A. state a historian’s ideasB. argue against a historianC. attract readers to study historyD. describe the story of a historianDA recent report says we spend an average of two hours and 40 minutes each day looking at a smartphone. That doesn't mean making calls, but using apps and browsing the Web.Spend that amount of time staring at anything. Checked our email in a restaurant, shared a picture of the food when it arrived, or checked a fact during a conversation only to be drawn into reading more instead of contributing verbally. It's no secret our lives are being affected by our obsession with smartphones.However, never before has this phenomenon been displayed so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10. 5 million times.Ironically, YouTube's statistics show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phone.The short film, written by and starring actress Charlene deGuzrnan, shows groups of people in various social situations, the majority of which are completely attracted by their phones instead of the world around them. It's depressing because we' ve all seen it, and sad because to a certain extent, we all do it.32. What did the author think of looking at a smartphone?A. Supporting.B. Surprising .C. Relaxing.D. Concerning.33. Which of the following can best replace the phrase "obsession with" in paragraph 2?A. contribution toB. addiction toC. boredom byD. annoyance about34.

At the gathering, a man called Douglas was again and again talking about Lincoln's low position in life and saying that he first met Lincoln when Lincoln was a shop assistant at a village shop. Finally, he said, “And Mr. Lincoln was a very good shop assistant, too.”People burst into laughter, but they quieted down when Mr. Lincoln said calmly, “Gentleman, what Mr. Douglas has said is true. I did sell cotton, candles and cigars, and sometimes whisky. But I remember that in those days Mr. Douglas was one of my best buyers. I often stood on one side of the counter and sold whisky to Mr. Douglas on the other side, but the difference between us is：I have left my side of the counter, but Mr. Douglas still_sticks_to_his_as_firmly_as_ever.”25．The story took place at a ________.A. meetingB.restaurantC. concertD. gettogether26．Why was Mr. Douglas again and again talking about Lincoln's low position in life?A. Because he was friendly to Lincoln.B. Because Lincoln was an example to show that an American of low position in life can become President of the US.C. Because he wanted others to look down upon Lincoln.D. Because he wanted to tell other people about Lincoln's friendliness as a shop assistant.27．How did Lincoln win the debate?A. He won it by telling of his low position in life in his early days.B. He won it by telling of his high position in life in his early days.C. He won it by saying Douglas was telling a lie.D.

That’s how thousands of people start their day at Laughter Clubs around the world – and many doctors now think that having a good laugh might be one of the best ways to stay healthy.The first Laughter Club was started in Mumbai, India, in 1995 b y Dr Madan Kataria. “Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing –it’s the universal language. We want people to feel happy with their lives.” There are no w more than 500 Laughter Clubs in India and over 1,300 worldwide.Many doctors are also interested in the effects (效果) of laughter on our health. According to a 5 – year study in the body. Laughter improves our health against illness by about 40%.So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest –I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha,” while looking at each other. However, our bodies can’t tell the difference between fake laughter and real laughter, so they still produce the same healthy effects.Surprisingly, it works! After ten minutes everybody in the room was laughing for real – and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very ple ased with the results!57．In which country was the first Laughter Club started?A．Britain. B．America. C．Australia. D．India.58．How did the writer feel at the beginning of the class?A．Surprised. B．Pleased. C．Nervous. D．Stressful. 59．When did the people in the club begin to laugh for real?A．After a few minutes. B．After a few hours.C．After a few seconds. D．After a few days.60．Which of the following is true according to the passage?A．Fake laughter and real laughter are both good for health.B．40% of the people in Laughter Clubs are good friends.C．Adults laugh more often than children in a day.D．Laughing is the best way to prevent illness.CThe Key to Your HealthA car needs gas to run and your body also needs food to work for you. Eating the right kind of food is very important. It can help your body grow strong to take care of what you eat.There are four main food groups altogether. The dairy group has food like milk, cheese and sour milk. The other three groups are the meat and fish group, the fruit and vegetable group, and the bread and rice group. Each meal should have at least one food from all four main groups. Withall these food together, you will be given enough energy during the day.It is easy to get into bad eating-habits. You may eat your breakfast in a hurry to get to school on time. Or you may not have time for a good lunch. It may seem easy to. But you will find yourself tired in these days and you can not think quickly.Watching what you eat will help your body remain healthy and strong. It is also good to take some exercise. It will help you eat more if you take a walk or play games in the open air. Having a good eating habit with some exercise is the key to your health.67．Which of the following diets do you think is the best one?A．Corn, fish，cream and pork. B．Eggs, tomatoes and chicken.C．Milk, bread, cabbages and beef.

In its original sense, however, culture includes all identifying aspects of a racial group, nation, or empire: its physical environment, history, and traditions, its social rules and economic structure, and its religious beliefs and arts.The central beliefs and customs of a group are handed down from one generation to another.It is for this reason that most people regard culture as learned rather than innate. People acquire a culture because they are not born with one. The process by which a person develops a taste for regional foods, accented speech, or an outlook on the world over time, therefore, is known as enculturation (文化适应).Cultures are often identified by their symbols —images that are familiar and coated with meaning. Totem poles (图腾柱) carved with animals and creative figures suggest aspects of the Native American peoples of the Pacific Northwest but more literally represent specific tribes (部落). In Asia and India, the color of yellow is connected with temples while in ancient China it was a color only the emperor’s family was allowed to wear. Thus, different cultures may respond to a symbol quite differently. For example, to some a flag may represent pride, historical accomplishments, or ideals; to others, however, it can mean danger or oppression.To individuals unfamiliar with cultures outside their own, the beliefs, behaviors, and artistic expression of other groups can seem strange and even threatening. A society that ranks all other cultures against its own standards is considered to be ethnocentric (from the Greek ethnos, meaning “people,” and kentros, meaning “center”). A strongly ethnocentric society assumes also that what is different from its own culture is likely to be inferior and, possibly, wrong or evil.All people are ethnocentric to some degree, and some aspects of ethnocentrism, such as national pride, contribute to a well-functioning society. An appreciation for one’s own culture, however, does not prevent acceptance and respect for another culture. History documents the long-term vigour and success of multicultural groups in which people from numerous and various cultural backgrounds live and work together. Extreme ethnocentrism, in contrast, can lead to racism — the belief that it is race and racial origin that account for variations in human character or ability and that one’s own race is superior to all others.87. What does the word “innate” in Paragraph 2 most probably mean?A. Instinctive.B. Developed.C. Believable.D. Cultivated.88. Which of the following is true according to the passage?A. Different interpretations of a symbol help to distinguish one culture from another.B. An ethnocentric country opens welcoming arms to cultures different from its own.C. Culture consists of some positive features of a racial group, nation or empire.D. People from various cultural backgrounds often reach an agreement on some image.89. What can be inferred from the passage?A. All aspects of ethnocentrism can produce negative effects on a society.B. Racism is unlikely to bring about serious conflicts among different cultures.C. Respect and acceptance of different cultures are a proper cultural attitude.D. Countries with a strong sense of national pride play a superior role in the world.90. Which might be the best title of the passage?A. Culture, the origin of racial superiorityB. Culture, a faithful mirror of historyC. Culture, the vigour of world developmentD. Culture, a distinctive identity of a nation第二节（七选五共5小题，每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
