The dog’s owners, Ron, his wife, Lisa, and their little boy, Shane, were very 88. I told th e family we couldn’t do 89 for Belker, and I told them that they could give the old dog the euthanasia procedure(安乐死)in their home.The next day, I felt a catch in my throat as Belker’s family was around hi. Shane petted(爱抚)the old dog for the last time. In a few minutes, Belker died . The little boy seemed to accept Belker’s death. We sat together for a while after Belker’s death, talking about why animal lives are shorter than human lives. Shane, who was listening quetly, said, “I know .”“People are bo rn so that they can learn how to live a good life like loving everybody all the time and being nice, right?” Shane said, “Well, dogs already know how to do that, so they don’t have to stay as 92 as human beings.”So remember, if a dog was the teacher, you would learn things like:When loved ones come home, always run to meet them.Run, 93 , and play daily.Let people touch youOn hot days, drink lots of water and lie under a big tree.When you are happy, dance aroundNever pretend to be something you’re notWhen someone is having a bad day, be silent, sit close by and nuzzle(轻触)them.Love people and don’t remember the wrong things they do 94 you.88.

Read the passage and fill in the blanks with proper words(在短文的空格内填入适当的词,使其内容通顺,每空格限填一词,首字母已给)More and more Japanese teenagers read novels on mobile phones(手机), n 95 on the paper.The phone novels are usually written by first-time writers usually in their tens or twenties. Several novels have been turned into real books. Love Sky, a story a 96 a boy with cancer, has sold more than 1.3 billion books and has been made into a f 97 .Many of the phone novels are influenced by comic(漫画)books because comic books are very popular in Japan. So phone novels are heavy in dialogue and have r 98 short paragraphs. Large empty spaces between sentences are used to mean that the characters are thinking.A mobile phone novel website, Maho i-Land which started several years ago, now has six million members and amillion novels on the site.However, some t 99 writers are angry about phone novels. They c 100 that phone noels are short of scene(缺少情景)and character development.Koichiro Tomioka, a professor at Kanto Gakuin University, said it was a new w 101 for writers to become known.He said, “It’s interesting. The problem is: can this new type of writer keep on writing books as a pro fessional writer?”E. Answer the questions(根据短文内容回答下列问题)Nowadays there is less and less contact(联络)between the old and the young. There are mainly four reasons for this, including the breakdown of the big family, working parents with little time to take care of their children, families that have moved away, and smaller flat with no room for grandparents. But the result are the same –increasing numbers of children without grandparents and old people who have no contact with children, more old people who are lonely and feel useless, and more and more families with young children who need more love and care. It’s a big problem in many countries.Now intergenerational(代际交流)programmes, designed to bring the old and the young together, are growing popular all over the world. There are successful examples of such programmes. There are schemes(方案)which involve older people visiting families who are having problems, maybe looking after the children for a while to give the tired mother a break. Or “adopt a grandparent” schemes in which children write letters or visit a lonely old person in there area. One successful scheme in London pairs(使结对)young volunteer with old people who are losing their sight. The young people help with practical things such as reading newspapers, reading bank statements and helping with shopping, and the older people can pass on their knowledge and experience to their young visitor. For example, a retired judge may be paired with a teenager who wants to study law.If older people can understand and accept the youth of today, and so do the youth, there will be less conflict(矛盾)in the world.102. Is there more and more contact between the old and the young?.103 How many reasons are mentioned(提到)for this situation?.104. Many old people feel lonely and useless, don’t they?.105. What is designed to bring the old and the young together?.106. Where does the successful scheme pair young volunteers with old people who are losing their sight?.107. If you take part in the “adopt a grandparent” scheme, will you pass on your experience or visit a lonely old person?I will .\108. Why are intergenerational programmes growing popular all over the world?.IX. Writing(作文)109. Write a passage of at least 60 words on the topic “I need …”. (以“我需要…”为题写一篇不少于60个词的短文符号不占格。

The outsides of the umbrellas were often __48__ colorful paintings of flowers, birds, and other complicated designs. However, these easily broken paper umbrellas were not used to shield a person form rain. Women in the Qing dynasty used them to protect their skin from the sun. Umbrellas became very fashionable for both men and women and were viewed as a symbol of high rank in ancient Cinese __49__Silk cloth has an expensive and prized material for thousands of years. At first, only the Chinese knew how to make silk, and they kept their __50__ for a very long time.

This takes about three days. The silk farmers can then harvest the fibers and begin to __53__ them for use.

Reading ComprehensionA. Choose the best answerIn the 1850s, a vast wilderness(荒野)separated California from the eastern U. S. As a result, mail service to California was very slow.William Russell decided to change that. He and two partners selected a route from St. Joseph, Missouri(密苏里), to Sacramento, California. Then they purchased 400 horses, hired workers and set up relay stations(中继站)every 10 to 15 miles. Riders would change horses at these stations, and every 90 to 120 miles a new rider would take over.On April 3, 1860, their service, called the Pony Express, began. The mail deliveries reached California in about 10 days. The riders faced many risks(风险)from extreme weather, hostile(敌对)Native Americans and riding accidents. But they lost only one delivery during the service’s one and a half years’ in operation.The Pony Express service ended in October 1861 after a telegraph line across the U. S. was completed. Yet the riders’ courage and accomplishments(成就)still hold a place in legend.Today, you can visit an original Pony Express station. Called the Hollenberg Station, it is located near Hanover, Kanas(堪萨斯州). The station was originally a five-room building in which Gerat Hollenberg and his wife sold supplies and provided meals for people who were travelling to California and Oregon. The couple also rented out rooms and repaired wagons(货车)for weary travelers. While the Pony Express was in operation, riders changed horses at the station and obtained both food and shelter there.The station is now a historic landmark. For a few dollars, you can tour the site. In a nearby visitor center, there is also a small gift shop and a theater where you can see films about the station.69. William Russell and his partners started the new service to _______.A. hire some workers to raise the horses they had purchasedB. challenge the risks like extreme weather and riding accidentsC. make their mail delivery famous and expand it to other countries.D. speed up the mail service so that it could become much faster70. The Pony Express, managed by Russell and his partners, _______.A. lasted for nearly 1.5 yearsB. never lost any deliveryC. set up relay stations every 15 milesD. began in October, 186171. What the riders did was _______. Which of the following adjectives is not so appropriate(合适的)to complete the sentence?A. dangerousB. usefulC. unforgettableD. exciting72. Gerat Hollenberg and his wife would _______.A. sell supplies to the touristsB. repair wagons for tired travelersC. rent out rooms if travelers neededD. do all of the above73. Since the 1860s , the Hollenberg Station has become_______.A. a center of researchB. a tourist attractionC. a set for moviesD. a social club74. The best title of the passage should be _______.A. Mail service to CaliforniaB. The Pony ExpressC. Horese at the Pony Express stationsD. The business run by HollenbergB. Choose the words or expressions to complete the passageA team of students who were successful in their work got together to visit their old teacher after graduating from college may years later. The talk soon turned into complaints about __75__ in work and life.Before offering his students coffee, the teacher went to the kitchen and returned with a large pot of coffee and different kinds of cups - plastic, glass, porcelain(陶瓷), crystal, some common and cheap, some beautiful and __76__ - telling them to help themselves to the coffee.After all the guests had a cup of coffee in hand, the teacher said: “If you noticed, all the nice -looking expensive cups were taken, leaving behind the common and cheap ones. While it is __77__ for you to want only the best for yourselves, that is where your problems and stress come from. We all know that the cup itself __78__ no quality to the coffee. In most case, it is just more expensive and in some cases even hides what we drink. What all of you really wanted was coffee, not the cup,but you all went for the best cups. And then you began looking at each other’s cups.”Now consider this: Life is the coffee: the jobs, money and position in society are the cups. They are just tools to hold life, and the type of cup we have does not decide, __79__ change the quality of life we live. Sometimes, by only paying attention to the cup, we fail to enjoy the coffee God has provided us. God makes the coffee, not the cups. Enjoy your coffee!“The happiest people don’t have the best of everything. They just_______ the best of everything.” Live simply. Love generously. Care deeply. Speak kindly. Leave the rest to God.75. A. stress B. difficulty C. sadness D. loss76. A. excellent B. bright C. expensive D. comfortable77. A. careful B. natural C. polite D. formal78. A. increases B. affords C. adds D. provides79. A. also B. if C. for D. nor80. A. have B. use C. make D. putC.

When reading the book, I felt t ___88____ from time to time.D. Answer the questions. (根据短文内容回答下列问题)Microsoft is testing a new software and needs your help. Just send Gates’ email message to everyone you know, and you can get your prize money. Does this sound too good to be true? This offer from Gates is a hoax(骗局). In fact, anyone with common knowledge in computers could tell whether it is true. But that hasn’t stopped the hoax from spreading across the Internet like wildlife. Millions of Internet users have sent this untrue message.The Internet is full of hoaxes, lies and wrong information. They are passed through e-mails, discussion groups and official-looking websites. Although most of them have been made known to the public what they are, it’s still hard to kill a “good hoax”. Most Internet hoaxes are similar. They often meet the needs of basic human feelings, like fear, greed or pity for others. Most importantly, they often sound as if they could be possible.If you’ve ever been fooled by a hoax, you are certainly not alone. Several famous newspapers have reported information they got online, only to later learn it was only a hoax. Even public official can something be fooled. The city officials in California learned from a website that Styrofoam(塑料泡沫) cups are made with a dangerous chemical, so they ordered that the cups should not be produced. They felt foolish, however, when they learned that chemical’s common name—water. Another hoax caused fear in Hong Kong. A website with the name of a famous newspaper reported that the government planned to order local people to stay in their homes for the reason of unknown disease. As a result, worried people crowded the supermarket to buy daily products. Financial markets began to fall, too.It’s sometimes hard to know what’s real and what’s not. Use the Internet, but don’t believe everything you read online.88. Can you get your prize money if you send Gates’ email message to everyone you know?89. How is the wrong information on the Internet passed?90. Why is it still hard to kill the Internet hoaxes?91. What did the city officials in California do after they learned the hoax?92. Where did the worried people in Hong Kong go to buy daily products?93. What’s the writing purpose of the passage? Please list two points.VII. Writing (作文)94. Write at least 60 words about the topic “Life needs …….” (以’生活需要….‘为题写一篇不少于60个词的短文,标点符号不占格)提示:生活五味杂陈,需要我们的一些品质,爱好,技能或行为等才能彰显其美的真谛。

Answer the questions(根据短文内容回答下列问题)Nowadays there is less and less contact (联络) between the old and the young. There are mainly four reasons for this, including the breakdown of the big family, working parents with little time to take care of their children, families that have moved away, and smaller flat with no room forgrandparents. But the result are the same–increasing numbers of children without grandparents and old people who have no contact with children,more old people who are lonely and feel useless, and more and morefamilies with young children who need more love and care. Itproblem in many countries.Now intergenerational(代际交流)programmes, designed to bring theold and the young together, are growing popular all over the world. Thereare successful examples of such programmes. There are schemes(方案)which involve older people visiting families who are having problems, maybelooking after the children for a while to give the tired mother a break. Or“ adopt a grandparent”in whichschemeschildren write letters or visit alonely old person in there area. One successful scheme in London pairs(使结对) young volunteer with old people who are losing their sight. The youngpeople help with practical things such as reading newspapers, reading bankstatements and helping with shopping, and the older people can pass ontheir knowledge and experience to their young visitor. For example, aretired judge may be paired with a teenager who wants to study law.If older people can understand and accept the youth of today, and sodo the youth, there will be less conflict(矛盾)in the world.102.

Answer the questions(根据短文内容回答下列问题)Nowadays there is less and less contact(联络)between the old and the young. There are mainly four reasons for this, including the breakdown of the big family, working parents with little time to take care of their children, families that havemoved away, and smaller flat with no room for grandparents. But the result are the same – increasing numbers of children without grandparents and old people who have no contact with children, more old people who are lonely and feel useless, and more and more families with young children who need more love and care. It’s a big problem in many countries.Now intergenerational(代际交流)programmes, designed to bring the old and the young together, are growing popular all over the world. There are successful examples of such programmes. There are schemes(方案)which involve older people visiting families who are having problems, maybe looking after the children for a while to give the tired mother a break. Or “adopt a grandparent” schemes in which children write letters or visit a lonely old person in there area. One successful scheme in London pairs(使结对)young volunteer with old people who are losing their sight. The young people help with practical things such as reading newspapers, reading bank statements and helping with shopping, and the older people can pass on their knowledge and experience to their young visitor. For example, a retired judge may be paired with a teenager who wants to study law.If older people can understand and accept the youth of today, and so do the youth, there will be less conflict(矛盾)in the world.102.
