Well, these rocks have clever contours (轮廓) on their surface which means that they can be piled up and used to construct all kinds of structures limited only by your imagination. Xeko Trading Card GameFrom the recycled lovely packaging to the very theme of the game, the Xeko trading card game is environmentally friendly. But wait! There’s more! The Xeko game teaches your kids lots of interesting stuff about the earth and its inhabitants (居民). Kids who tried this game found it totally cool. It may be a good idea to introduce this trading card game to your kids, especially if they display an interest in math and science.56. What do we know about ImagiPlay Puzzles?A.

It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.The nature of what is news may change. What basically makes news is what affects our lives—the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research,though. It's already happening in areas that may directly affect our lives,like genetic engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do—as we develop a better understanding of how the brain operates and what our feelings really are.It's quite possible that in the next century newspapers will be transmitted electronically from Fleet Street and printed out in our own home. In fact, I'm pretty sure how it will happen in the future. You will probably be able to choose from a menu, making up your own newspapers by picking out the things you want to read—sports and international news, etc.I think people have got it wrong when they talk about competition between the different media.They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn't happened. What it read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet,it's never really pleasant to read something just on a screen.61.What is the BEST title for the passage?A. The best way to get newsB. The future of newspaperC. Make your own newspaperD. The changes of media62.In the writer's opinion,in the future, .A. more big political affairs, wars and disasters will make newsB. newspapers will not be printed in publishing houses any longerC. newspapers will cover more scientific researchD. more and more people will watch TV63.What will probably be in the newspaper made by yourself?A. What you are interested in.B. A menu of important news.C. The most important news.D. Sports and international news64.From the passage, we can infer .A. newspapers will win the competition among the different mediaB. newspapers will stay with us together with other mediaC. television will take the place of newspapersD. the writer believes some media will die out65.The underlined phrase “feed off” in the last paragraph means .A. kill offB. compete withC. fight withD. depend onCLivia Satterfield, born in Romania, never received a Christmas gift until she was 12. She grew up in a Romanian orphanage(孤儿院), and that first gift, a shoe box full of inexpensive things with hair barrettes sitting on top — she had always longed for such a set — changed her life. Connie Satterfield from America put the box in Livia’s hands 10 years ago when she was volunteering for the Operation Christmas Child.Franklin Graham runs the Operation Christmas Child now. The program began in 1990 in Wales when a pastor(牧师)gathered 23,000 boxes of toys for child victims of the civil war in the former Yugoslavia(南斯拉夫). The pastor later hired Graham to join, and collected 69 million shoe boxes. The program continues to grow now. This year it will send about 8 million shoe boxes full of pencils, toothbrushes, dolls and balls.Connie Satterfield said she and her husband, Ray, had talked about adopting an American child, but held off because they had a 4-year-old. However, everything changed soon when she handed Livia her box. “I saw and talked to the child, and it’s the child who I want to have. The very day I met her, I knew,” she said.The adoption process took nearly two years. Two years later, Livia reached America and became a member of the Satterfields when she was fourteen.Livia, now 22 and a student at Clayton State University, is packing the boxes for distribution worldwide. She’s working at the Suwanee storehouse where 8,000 volunteers will inspect, sort and pack 850,000 shoe boxes given by kind people. She hasn’t forgotten her first Christmas gift. That’s why she’s volunteered for several years for the yearly gathering of gifts. She wants to work full time for the organization that changed her life.66. From Paragraph 1, we can learn that Livia Satterfield______.A. had a miserable(痛苦的,可怜的) childhoodB. lost touch with her parentsC. got much care from the orphanageD. was encouraged to change her life by Connie67. What can we learn about the Operation Christmas Child?A. It is a for-profit organization.B. It was created by a British pastor.C. It buys expensive gifts for orphans every year.D. It sends only shoe boxes to children.68. When Connie Satterfield saw Livia, she______.A. wanted to adopt LiviaB. had no child in her familyC. told her husband to adopt LiviaD. didn’t intend to adopt a foreign girl69. What can we infer from the text?A. Livia was adopted when she was 22.B. Connie didn’t like Livia at first.C. Connie Satterfield had difficulties in adopting Livia.D. Livia asked Connie Satterfield to adopt her.70. Livia Satterfield works for the Operation Christmas Child because she______.A. wants to help her motherB. can’t find other better jobsC. plans to start a new lifeD. wants to pass on love to othersPart IV Writing (45 marks)Section A (10 marks)Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.Career development refers to the life-long process of continuously managing professional work. The process assists people in defining their career goals clearly.Education is the first step in career development because education received in various institutions like elementary school, high school and university helps in increasing the depth of a student’s knowledge.Career development is also concerned with personality as a person needs to present himself in the best possible way in his workplace to make a mark for himself. Relevant personal qualities are important, such as loyalty to the company, responsibility and so on.Career development also emphasizes the important aspects of training. Knowledge learned in classrooms needs to be applied smartly to doing the work in a satisfactory way. For this, a good deal of training needs to be provided for the employees by their employers. Get as much training as possible!There are many objectives of career development, one of which is identifying your strengths and weaknesses. Your career won’t move in a wrong direction only if you make a concentrated effort of making full use of your strengths and working on your weaknesses. A person can understand his worth with the help of career development.Because of the development of globalization, employees may have to work in different places across the world. Therefore, adapting to the conditions that are changing is also one objective of career development. In the absence of career development programs, employees may witness a reduced productivity which will affect their career advancement.Information is another objective of career development. Employees and students must have right information about career planning and various opportunities available to them at the right time to take opportunities and achieve their goals. They need to be aware of the skills and qualities which are essential in a modern business environment.As has been stated above, one really has to do a lot in the process of career promotion. But what’s the most important is that those who are going to create a bright career future must struggle to improve themselves constantly in the whole life span.Section B (10 marks)Directions: Read the following passage. Answer the questions according to the information given in the passage.I used to frequently visit an old age home in our city Hyderabad, India. There I met a gentlemen by name Kurien in his late eighties. He served the Indian army and retired. He had one son who was well educated and also married. He just did not bother to take care of him or respect him while he was in the house.Mr. Kurien got disappointed with the life in his house and decided to move into this old age home here in Hyderabad. We both began to share a lot of thoughts whenever we met and slowly it was a daily affair that I used to spend some time with him discussing what he had done in the army: their daily schedule, march pasts, camps etc., which he used to share with lots of joy.I used to carry with me some snacks which we both used to sit under a tree and eat. I saw him really very happy in my presence. One day, h e told me with tears in his eyes “John, I have really found a very good friend in you. I feel like living some more years to spend happy time with you.”As we departed (分开), I told him “Do not worry. God will give you enough time to spend with me.” I had an official meeting and could not the next day go to the old age home. The day after when I reached the home, his room was locked. I enquired and found that he was no more. He died the very night we both met last.I really miss him. I have not given him anything worthwhile, except that I used to listen to his words and share his thoughts. Let’s share what we can.81.

The day I was given the news was a cold Saturday. My mom sat me on the floor and opened her mouth to give me the most 1 words I'd ever heard: “Grandma Billie has been diagnosed with cancer.” Tears filled my eyes immediately. Mom continued, “Grandma is old and her body is too 2 . There’s nothing they can do to treat her.” I knew this wasn't my mom’s fault but I was so 3 . I was almost yelling at my mom, “So, they’re just going to let her 4 ?”We had to just wait for her to die. I couldn't even 5 the thought. We went to th e hospital right away. The doctor said, “Billie has a tumor in her 6 . She won't be able to 7 because it hurts her too much. One option is a feeding tube, but there are times when it will be uncomfortable.” At the end, the doctor sighed, “With a f eeding tube, she would probably have three 8 at most.”My whole family on my mom’s side was really 9 and they were all looking to God to make this easy. I couldn't handle it. If God was so wonderful and so 10 then why did he allow all these awful things to happen to good people? Why was he letting my grandma die?I came and visited every day after 11 practice. Grandma would tell me the12 stories over and over again, but every time I was just as surprised and excited to hear them. She was getting 13 really fast and every time I came to see her it broke my heart more.3 weeks later, after the softball practice, I was getting ready to see grandma when mom appeared in the locker room. She opened her mouth but at first no words cameout. She 14 again, “You can’t go to see grandma today because she just died.” Silence. I couldn’t 15 anyone else in the room.

It is known that flowers of different plants open and close at different times of day. This is so 1 that there seems to be no need to ask the reason for it. Yet no one 2 understands why flowers open and close like this at particular times. The process is not as 3 as we might think, as recent experiments have shown. In one study, flowers were kept in constant 4 . We might expect that the flowers, without any information about the time of day, did not open as they 5 do. As a matter of fact, they 6 to open at their usual time. This suggests that they have some mysterious(神秘的) way of knowing the 7 . Their sense of time does not 8 information from the outside world; it is, so to speak, inside them, a kind of “inner clock”.This 9 may not seem to be very important. However, it was later found that not just plants but also 10 , including man, have this “inner clock” which11 the working of their bodies and influences their activities. Men, then, are also influenced by this mysterious 12 . Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.In the past, this did not really 13 because people lived in natural condition. In the 14 world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who have to work at night. It would be very 15 , then, to know more about the “inner clock”. Such things as flowers might help us understand more about ourselves.1. A. familiar B. strange C. similar D. special2.

AThe writers of murder stories go to a great deal of trouble to keep us guessing right up to the end. In actual fact, people often behave more strangely in real life than they do in stories.The following advertisement once appeared in a local newspaper: "An opportunity to earn $250 in a few minutes. A man willing to take chances is wanted for an out-of-the-ordinary job which can be performed only once." A reader found this offer very generous and applied to the advertiser, but being a bit suspicious, he gave a false name. Soon afterwards, he received a reply. Enclosed in the envelope was a typed note instructing him to ring a certain number if he was still interested. He did so and learned on the telephone that the advertiser wanted him "to get rid of somebody" and would discuss it more fully with him the next day. But the man told the police and from then on acted under their instructions.The police saw the two men met and watched them as they drove away together. In the car the advertiser came to the point at once: he told the man he wanted him to shoot his wife. The reason he gave was that he was suffering from an incurable disease and wanted to live in a warmer country,but his wife objected to this. Giving the man some money,the advertiser told him to buy a gun and warned him to be careful of the dog which,though it would not bite,might attract attention. He also gave him a photograph of his wife so that he would be able to recognize her,After that,the advertiser suggested that the man should "do the job" next morning. Meanwhile,he would prepare his wife by telling her that a young man was going to call. After the murder,they would meet again outside a railway station and the money would be paid as arranged. The second meeting never took place,for the advertiser was arrested shortly afterwards and charged with attempting to persuade someone to murder his wife.26. What can we infer from paragraph one?A. While reading murder stories, we have to guess at the end of the stories.B. While reading murder stories, we have to guess from the beginning to the end.C. People usually behave more strangely in murder stories than in real life.D. It is very easy for writers of murder stories to have readers guessing.27. The underlined word ―suspicious‖ in paragraph two means _________?A. doubtfulB. sureC. persuadedD. unexpected28. Why did the man put an advertisement in a local newspaper?A. To hire someone to kill himself because he was seriously ill.B. To ask someone to buy a gun for him and then he would kill his wife.C. T o hire someone to kill his wife because he didn‘t love her any more.D. To have his wife killed because he doubt whether she still loved him.29. According to the passage, what is NOT true about the advertiser?A. He was suffering from a deadly disease.B. He raised a dog in his house.C. He would help the person hired to finish the task.D. He paid the man he hired beforehand.30. From the passage, we can learn that___________.A. The advertiser wrote a letter to the reader to ask him to call a number.B. The reader was in great need of money, so he wanted to get the job.C. The advertiser was caught by the police right after he met the reader.D. The dog in the advertiser‘s house was very fierce.BA homeless man in Las Vegas who had been living on the streets and had not seen his six children for nearly 25 years has been reunited with his daughter thanks to modern technology and the kindness of strangers.Jimmy Francis was outside a Firehouse Subs shop earlier this month when he was spotted by a local realtor Jim Snyder, as he was going in to pick up his dinner. When Snyder saw Francis struggling in the cold weather, he, with the help of Firehouse employees, bought the man a sandwich and gave him some cash.After Snyder got home his thoughts stayed with Francis, left out in the cold. ―He was shaking so uncontrollably and was so cold. I t just broke my heart and I thought there‘s something I‘ve got to do here,‖ Snyder, 49, told . ―By the time I got to where my home is, I knew I had to turn around and get him.‖Snyder, who says he had never before done anything like that, brought Francis to the home he shares with his wife, Maria, and gave him coffee, a warm shower, washed his clothes and packed a suitcase full of his own old clothes for Francis.Over coffee and a warm meal, Snyder, himself a father of five children and step-children, learned that Francis had not seen his six children for over two decades after a divorce. He was particularly torn, Snyder says, over not seeing his only daughter,Natalie.―He told me he had colon cancer in 2010 and wasn‘t expected to live and because of that experience, the one thing constantly in his mind is that he wants to be reunited with his children,‖ Snyder said.The Snyders took down the names and birth dates of Francis‘s children and used social media to search for them.The couple found Natalie Francis, now living in Northern California and herself a grandmother, on Facebook and sent her a message. Less than one hour later, they had a response.―The message just said, ‗Oh my God. This is my dad. Is he okay?‘‖ Snyder recalled.Just days later the couple brought Francis, living temporarily with an acquaintance, back to their home for a Skype call with his daughter.―A whole lot of emotions,‖ is how Snyder recalled the virtual reunion. ―That was the first time they‘d seen each other in 24 years, literally. It was very, very special.‖31.According to the passage, we can know that ___________.A.Jimmy Francis has been living on the streets for nearly 25 yearsB.Jimmy Francis was once a friend of Jim SnyderC.Jim Snyder felt pity for Jimmy Francis when he saw himD.Jimmy Francis was dying when Jim Snyder saw him.32.According to the passage, what is TRUE about Jim Snyder?A.He always brings homeless strangers home.B.He lives with his wife and his children.C.He himself has probably once divorcedD.He has three sons and two daughters.33.What does the passage suggest?A.Jimmy Francis thought he was going to die because of cancer.B.Jimmy Francis has been looking for his children for more than 20 years.C.Jimmy Francis could hardly remember his children‘s names and birth dates.D.Jimmy Francis‘s wife died and he was so sad tha t he left home.34.

How far would you go if you had a 70 to 90 percent chance of contracting bowel(肠)cancer -- and your uncle, mother, father, and two of your brothers had died from it?Lynne Fisher decided she would do almost anything. So, even though she showed no signs of cancer at all, Fisher, 51, a former mental health worker, agreed to undergo what might sound like a radical surgery: doctors removed nearly her whole colon(结肠) and rerouted her small intestine(肠) to perform the functions of her large intestine.The side effects were horrific, she said. For a year, Fisher struggled to control her bowel movements. She fought depression, and she hated her large scars and the 28 staples that had been left in her body. Her Multiple Sclerosis returned. The woman she shared a hospital room with -- who'd had a similar surgery -- did not survive."When you're in it, it's like a dark tunnel," she told ABC News in a long phone conversation about her medical history.But then, one day, she realized the surgery had helped saved her life. And since then, she's never looked back."What's a year out of your life compared to dying?" the 51-year-old said from her home in central England. "I get to watch my dogs grow up, my children grow up, my grandchild, I get to see my cherry blossoms in the tree, I get to see the sun shining in the morning, I get to go on holiday -- I get to see life."Genes that cause breast cancer have been discussed widely for years. But less well known is Lynch syndrome, the gene mutation that Fisher and her much of her family inherited.Roughly one in 370 people has Lynch syndrome, according to Lynch Syndrome International, an organization dedicated to helping people with Lynch syndrome and those who treat them. It's unclear how many Americans choose to have the surgery that Fisher had: prophylactic subtotal colectomy, which doctors describe as a major surgery that, while elective, can often save lives.36.Why did Lynne Fisher decide to remove nearly her whole colon?A. Because she has already had a cancer.B. Because she thought the colon was useless.C. Because she was afraid of dying of bowel cancer someday.D. Because her doctor persuaded her to do that.37. According to the passage, what is NOT true about the surgery undergone by LynneFisher?A. It is only a very simple and easy surgery.B. It can bring about some terrible side effects.C. It‘s possible for one to die of the surgery.D. It takes one maybe a year to recover from the surgery.38. What can we learn from the underlined sentence?A. Lynne Fisher really regretted what she had done.B. Lynne Fisher thought it was not worth a year to have the surgery.C. Compared to death, the suffering during the year was worthwhile.D. Lynne Fisher spent a painful year in recovering from the surgery.39. What can we learn from the last paragraph?A. About 0.27% people have Lynch syndrome now in America.B. We can tell exactly how many people have had the surgery.C. Lynch Syndrome International helps people with Lynch syndrome only.D. People with Lynch syndrome will be forced to have the surgery.40. The main purpose of the passage is to _________.A. persuade people with Lynch syndrome to have a surgeryB. introduce Lynne Fisher and the disease she developedC. tell us something about the Lynch syndrome and its effect on our healthD. introduce Lynch syndrome to us and tell us that a surgery can save livesDIt turns out that nodding off in class may not be such a bad idea after all, as a new study has shown that going to sleep shortly after learning new material is the best way to remember it.According to US lead author Jessica Payne, a psychologist at the University of Notre Dame in Indiana, nodding off after learning something new is like ‗telling‘ the sleeping brain what to keep in memory. Along with colleagues, she studied 207 students who habitually slept for at least six hours per night. Participants were randomly assigned to study declarative, semantically related or unrelated word pairs at 9 a.m. or 9 p.m., and returned for testing 30 minutes, 12 hours and 24 hours later.Declarative memory refers to the ability to consciously remember facts and events, and can be broken down into episodic memory (memory for events) and semantic memory (memory for facts about the world). People routinely use both types of memory every day – recalling where we parked today or learning how a colleague prefers to be addressed. At the 12-hour retest, memory overall was superior following a night of sleep compared to a day of wakefulness. At the 24-hour retest, with all subjects having received both a full night of sleep and a full day of wakefulness, su bjects‘ memories were superior when sleep occurred shortly after learning, rather than following a full day of wakefulness.―Our study confirms that sleeping directly after learning something new is beneficial for memory. What‘s novel about this study is that we tried to shine light on sleep‘s influence on both types of declarative memory by studying semantically unrelated and related word pairs‖, Payne said. ―Since we found that sleeping soon after learning benefited both types of memory, this means that it would be a good thing torehearse any information you need to remember just before going to bed. In some sense, you may be ―telling‖ the sleeping brain what to consolidate (巩固).‖41. What does the underlined phrase nodding off mean?A. Going to sleep.B. Arguing with othersC. Asking questions.D. Answering questions.42. How many times will the participants tested?A. At least onceB. At least twiceC. At least three timesD. At least four times43. What can we infer from the passage about the study?A. Jessica Payne carried out the study all by herself.B. The 207 students were forced to sleep at least six hours per night.C. Participants were asked to memorize things according to strict rules.D. Participants could memorize what they learnt right before they slept best.44. What would Payne advise us to do?A. Memorize things after we have a good sleep.B. Memorize things just before our sleep.C. All the students go to sleep in class.D. Memorize things at mid-night.45. The text is most probably a _________.A. science reportB. book reviewC. science fiction storyD. newspaper advertisement.第二节:信息匹配(共5小题;每小题2分,满分10分)阅读下列应用文及相关信息,并按照要求匹配信息。
