She has thousands of happy memories of the dance floor---dancing the Tennessee Waltz with her husband. John Clayton. For the entire 58 years of their marriage, they 36 dancing every week. Coffey believes it was the waltz that kept the romance in their marriage alive for such a long time. “ The waltz can make us 37 through hugging and kissing.” Coffey once said.Clayton passed away 15 years ago, and Coffey has 38 to set foot on a dance floor since then because of her deep sadness. But now, she has been diagnosed (诊断) with serious heart disease, and is believed to have just six months 39 to live. When they learned her 40 , volunteers at Mesquite’s Christian Care Center asked Coffey what she had dreamed to do in her life. To their 41 , Coffey’s answer was simple: “one last Tennessee Waltz”.After a long discussion, the volunteers decided to make her dream come true. They prepared a party for the old woman secretly. They drove her to the romantic party in the Park Series on a Tuesday night. In the car, Coffey asked 42 , “ What are we going to do?” One of the volunteers 43 on purpose, “ Mary, we are going to someone’s birthday party.”Seeing all the volunteers that welcomed her at the party, Coffey was so 44 that she cried immediately. Then, Coffey was 45 to dance the waltz on the dance floor by one of the volunteers. During the first song, Coffey danced 46 , showing that she was still familiar 47 all the moves. Coffey soon became tired, however, she was excited that she had the opportunity to dance the wal tz one last time. She said, “I am very grateful! I will value this special memory forever!”36.

I think it is important to know about the customs and traditions of different countries in order to avoid misunderstanding.Last Saturday, I met a man from France, 49 explained to me how the French greet each other. Now I know that the French usually shake hands when they meet. If they know each other well, they kiss each other on the cheek. They shake hands again 50 they are saying goodbye. It is not unusual for a French person that you met several minutes ago to come and shake hands with you again! This is just 51 of many French traditions. If you went to live in France, you might find 52 hard to adjust 53 their ways.Almost every culture in the world has its own taboos, and it is important to be aware 54 these taboos, so you know what is considered appropriate. Breaking a taboo could be a very upsetting experience. For example, in Japan, 4 and 9 are considered to be unlucky numbers, since the Japanese words for these two numbers sound 55 ‘death’ and ‘suffering’. It would be important to know this if you would like to visit Japan on holiday.Part ⅢReading Comprehension (30 marks)Directions: Choose the one that fits best according to the information given in the passage.AWelcome to one of the largest collections of footwear(鞋类)in the world that will make you green with envy.

All we know is that a low level is harmful to brain development and makes a baby easily annoyed. In this state, the baby is difficult to calm down and sleep is impossible. The baby asks for attention by crying and searching for food with its mouth.It is not just unkind but also dangerous to say a four-hourly feeding schedule will make a baby satisfied. The first of the experts to advocate a strict clock-watching schedule was Dr Frederic Truby King who was against feeding in the nigh t. I’ve never heard anything so ridiculous. Baby feeding shouldn’t follow a timetable set by the mum. What is important is feeding a baby in the best way, though it may cause some inconvenience in the first few weeks.Well, at last we have copper-bottomed research that supports demand feeding and points out the weaknesses of strictly timed feeding . The research finds out that babies who are fed on demand do better at school at age 5, 7 , 11 and 14, than babies fed according to the clock. By the age of 8, their IQ (智商)scores are four to five percent higher than babies fed by a rigid timetable. This Research comes from Oxford and Essex University using a sample (样本)of 10,419 children born in the early 1990s,taking account of parental education,family income,a child’s sex and age,the mother’s health and feeling style.These results don’t surprise me.Feeling according to schedule runs the risk of harming the rapidly growing brain by taking no account of sinking blood sugar levels.I hope this research will put an end to advocating strictly timed baby feeling practices.61.According to Paragraph 2,one reason why a baby cries is that it feels______.A.sickB.upsetC.sleepyD.hungry62.What does the author think about Dr King?A.He is strictB.He is unkindC.He has the wrong idea.D.He sets a timetable for mothers63.The word copper-bottomed in Paragraph 4 is closest in meaning to _________.A.basicB.reliableC.surprisingD.interesting64.What does the research tell us about feeling a baby on demand?A.The baby will sleep well.B.The baby will have its brain harmed.C.The baby will have a low blood sugar level.D.The baby will grow to be wiser by the age of 8.65.The author supports feeling the baby_______.A.in the nightB.every four hoursC.whenever it wants foodD.according to its blood sugar levelCOne of the greatest contributions to the first Oxford English Dictionary was also one of its most unusual. In 1879, Oxford University in England asked Prof. James Murray to serve as editor forwhat was to be the most ambitious dictionary in the history of the English language. It would include every English word possible and would give not only the definition but also the history of the word and quotations (引文)showing how it was used.This was a huge task. So Murrary had to find volunteers from Britain, the United States, and the British colonies to search every newspaper, magazine, and book ever written in English. Hundreds of volunteers responded, including William Chester Minor. Dr. Minor was an American Surgeon who had served in the Civil War and was now living in England. He gave his address as “Broadmoor, Crowthorne, Berkshire,”” 50 miles from Oxford.Mi nor joined the army of volunteers sending words and quotations to Murray. Over the next years, he became one of the staff’s most valued contributors.But he was also a mystery. In spite of many invitations, he would always decline to visit Oxford. So in 1897,Murray finally decided to travel to Crowthorne himself. When he arrived, he found Minor locked in a book-lined cell at the Broadmoor Asylum for the Criminally insane.Murray and Minor became friends, sharing their love of words. Minor continued contributing to the dictionary, sending in more than 10,000 submissions in 20 years. Murray continued to visit Minor regularly, sometimes taking walks with him around the asylum grounds.In 1910, Minor left Broadmoor for an asylum in his native America. Murray was at the port to wave goodbye to his remarkable friend.Minor died in 1920, seven years before the first edition of the Oxford English Dictionary was completed. The 12 volumes defined 414,825 words, and thousands of them were contributions from a very scholarly and devoted asylum patient.66. According to the text, the first Oxford English Dictionary _________.A. came out before Minor diedB. was edited by an American volunteerC. included the English words invented by MurrayD. was intended to be the most ambitious English dictionary67. How did Dr. Minor contributed to the dictionary?A. He helped Murray to find hundreds of volunteers.B. He sent newspapers, magazines and books to Murray.C. He provided a great number of words and quotationsD. he went to England to work with Murray.68. Why did Dr. Minor refuse to visit Oxford?A. He was shut in an asylumB. He lived far from OxfordC.

Minor recovered with the help of MurrayD. Murray went to America regularly to visitMinor70. What does the text mainly talk about?A. The history of the English language.B.

Sleep is a natural part of human life, but many people in the modern world ignore its importance. As a result, sleep problems are increasingly common.In 2008, scientists at the University of Athens in Greece conducted a survey of 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Of the people that responded to the survey , 24 percent said that they did not sleep well, and based on their responses, 31.6 percent were diagnosed with insomnia(失眠症) and another 17.5 percent were diagnosed with borderline insomnia. In addition, 30.7 percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.Overall, the survey found that many people surfer the effects of poor quality sleep, some examples of which are becoming unable to fall asleep and waking up in the middle of the night. The main factors causing these problems are great pressure from school or work and a fast pace of life, but noise pollution and light pollution also interfere with sleep and contribute to poor quality sleep. The survey's findings are particularly troubling because larger numbers of people are found to have difficulty sleeping at night. The short-term effects are tiredness and trouble concentrating. If this happens for a long time, the risk of gaining weight and having a heart attack may increase.There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and get up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.Getting a good night's sleep is important for everyone. By following the advice above, you can rest better at night and work\study better during the day.Section B (10 marks)Directions: Answer the questions according to the information given in the passage.Ashley Power’s mother bought a computer for her when she was eight. When she was thirteen, she was surfing the Internet re gularly, but she couldn’t find anywhere for teenagers to meet and talk. And one day she thought, “If I had my own website, I’d make it a really interesting site for teenagers.”So, when Ashley was sixteen, she launched her own website, called Goosehead. She had no idea how big a success it would be, but three years later, the site was the most successful teen site in the USA! It was getting 100,000 hits every day, and Ashley had about 30 employees.After a few years, the website closed down. Then Ashley, who lives in Los Angeles, was asked to write a book called The Goosehead Guide to Life. The book is about how to design a website and start a business. It begins with a section called “All About Ashley,” where Ashley tells readers what it is like to be the boss of a company when you are only sixteen. “ I was so happy. But it was crazy in a lot of ways. I got very stressed. I mean, I was only sixteen —I didn’t even have a car! If you were sixteen and you had your own company, you’d be stressed, too!“In an interview Ashley gave advice to teenagers who wanted to start their own business, “Just be strong and have your dreams and work hard at them. And don’t listen when people tell you that you can’t do it, because I heard ‘no’ a lot. Just keep going until you hear ‘yes’!”81. For what purpose did Ashley create GooseHead?(no more than 10 words)82. What is the main idea of Paragraph 2?(no more than 6 words)83.
