So I thought it would offer a(n) 36 sight.We were standing in line for 45minutes to enjoy the 37 up to the watch point. When we got there, we went around the 38 of the tower and saw the hard wire fence 39 to the structure serving as a barrier. We went back inside to look for the glass floor that provided a direct view 40 . As soon as both of us 41 , we stopped before walking onto it. We found that our legs began to 42 . I stopped for a minute considering the step, taking several seconds to 43 the edge before moving.And then I had a thought in my mind:―It is far 44 compared to any other floor in this building. There is no real danger to me —it’s 45 an illusion. Look at all the people standing on it, and think about those who have stood on it before.‖I began to46 that step onto the gl ass floor. I didn’t look down —47 not for a few minutes.I walked on the 48 and looked around and thought about how 49 the experience was. I even found myself jumping up and down. There was no 50 , and it was certainly an illusion.I considered how many things in our lives we 51 and exactly how many of them are actually illusions. I thought about all the things we 52 ourselves from doing because we have 53 ourselves into thinking there’s risk. I thought about all the thi ngs that I still have yet to do that appeared 54 .

Y et, despite the competition, my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories. She wants to enter one of her stories into a writing contest, a competition she won last year.As a writer I know about winning contests, and about losing them. I know what it is like to work hard on a story only to receive a rejection slip from the publisher. I also know the pressures of trying to live up to a reputation created by previous victories. What if she doesn’t win the contest again? That’s the strange thing about being a parent. So many of our own past scars and dashed hopes can surface.A revelation (启示) came last week when I asked her, ―Don’t you want to win again?‖ ―No,‖ she replied, ―I just want to tell the story of an angel going to first grade.‖I had just spent weeks correcting her stories as she spontaneously (自发地) told them. Telling myself that I was merely an experienced writer guiding the young writer across the hall, I offered suggestions for characters, conflicts and endings for her tales. The story about a fearful angel starting first grade was quickly ―guided‖ by me into the tale of a little girl with a wild imagination taking her first music lesson. I had turned her contest into my contest without even realizing it.Staying back and giving kids space to grow is not as easy as it looks. Because I know very little about farm animals who use tools or angels who go to first grade, I had to accept the fact that I was co-opting (借用) my daughter’s experience.While stepping back was difficult for me, it was certainly a good first step that I will quickly follow with more steps, putting myself far enough away to give her room but close enough to help if asked. All the while I will be reminding myself that children need room to experiment, grow and find their own voices.56. What did the author say about her own writing experience?A. She was constantly under pressure of writing more.B. Most of her stories had been rejected by publishers.C. Her way to success was full of pains and frustrations.D. She did not quite live up to her reputation as a writer.57. Why did Rebecca want to enter this year’s writing contest?A. She wanted to share her stories with readers.B. She had won a prize in the previous contest.C. She was sure of winni ng with her mother’s help.D. She believed she possessed real talent for writing.58. The author took great pains to refine her daughter’s stories because ________.A. she wanted to help Rebecca realize her dream of becoming a writerB. she believed she had the knowledge and experience to offer guidanceC. she did not want to disappoint Rebecca who needed her help so muchD. she was afraid Rebecca’s imagination might run wild while writing59. What’s the author’s advice for parents?A. Children should be given every chance to voice their opinions.B. Children should be allowed freedom to grow through experience.C. Parents should keep an eye on the activities their kids engage in.D. A writing career, though attractive, is not for every child to pursue.BPeople in the UK often talk about their homes: their mortgages (按揭), the interest rates, and rising prices. Here’s a guide to some of the words and phrases you might come across.It’s a go od idea in the UK to arrange a mortgage with a bank before you start looking. This is when the bank tells you how much money they will lend you so you have a good idea of how much you can afford.The next step is to go to an estate agent and see what sort of properties they have available in your budget range and in your area. If you see something you like, the estate agent will arrange for you to view the property, so that you can see the house or flat for yourself.If you see something that takes your eye, you put in an offer. The vendor (卖家) can accept or decline this offer, and if the vendor accepts it, you can move forward with the sale. However, as you don’t pay any money at this point, the offer isn’t legally binding (具有约束力), and in theory, you can pull out of the offer at any time that you like.Y our next step will probably be to get a structural survey done. A qualified surveyor will inspect the house and write a report that illustrates any structural problems, like damp or drainage problems.If you still want to go ahead with the sale, you need to appoint a lawyer to do the legal paperwork.. If you already own a house, you might also be busy trying to sell it. Many house owners prefer to sell to first-time buyers (those people who don’t alrea dy own a home), as they are not in a chain (waiting for other people to buy the house before they can buy their next house).Finally, once the contracts are signed and exchanged, you complete on your house. Y ou get the keys and you can move in whenever you want. Then you might want to throw a house-warming party. Congratulations!60. Which of the following shows the right order of what happens before the people in the UK moveinto a new house?a. ask for a company which represents others of propertiesb. decide how much to borrow from the bankc. examine the structure of the housed. hire a lawyer and make a contracte. offer the seller the right moneyf. visit the house and discuss a price with the sellerA. b, a, f, d, c, eB. b, a, f, c, d, eC. b, a, f, e, d, cD. b, f, d, e, c, a61. According to the passage, these statements are correct EXCEPT ___________.A. People can borrow the whole money for a new house from a bank.B. People care for mortgages, interest rates and the prices &house.C. The sellers are more interested in the first-time buyers.D. After getting the keys, the owners sometimes have a party.62. Which of the following is NOT mentioned in the passage?A. Owners.B. Surveyors.C. Lawyers.D. Collectors.63. The passage is maybe one that _______________.A. give some advice on the houseB. introduces a book on travelersC. give some tips to buyersD. introduces a guide to visitorsCHundreds of students from around the world gathered in New Y ork City last week for the Microsoft Imagine Cup finals. They came to present their ideas for using technology to solve world problems.Microsoft education director Suzi Levine says the nine-year-old program began mainly as a competition to create technology.SUZI LEVINE: "When we realized that students really actually want to have a purpose for what they're creating, we introduced the idea of inspiring them with the UN Millennium Development Goals and suggesting that they use those for their muse(灵感). "This past year we also rolled out something called the Imagine Cup Solve This library(创新杯求解计划知识库), where IGOs, NGOs and nonprofits can submit some of the technical challenges that they would like students to consider for their solutions."Microsoft says over 350,000 high school and college students registered for this year's competition. Judges chose more than four hundred of them to attend the finals.SUZI LEVINE: "One from Thailand was called NewKrean, where they created a Windows Phone 7 application that allows you to broadcast your location to your social network of friends so that you can be more easily rescued." They named their application Terra.Suzi Levine says there were also ideas from Egypt inspired by the revolution that overthrew president Hosni Mubarak in February.SUZI LEVINE: "One was to use Bluetooth as sort of a Twitter equivalent so that if the government shuts down the Internet, you actually can still have a massive social distribution."Students competed in nine categories. For example, in software design the top prize of twenty-five thousand dollars went to Team Hermes from Ireland. The students developed a device for cars to collect information on road conditions, driving behavior and traffic incidents.A team from Taiwan's National Tsing Hua University won first place in the embedded(内嵌的)development category. They developed a network of wireless devices to help plot the safest escape routes during a fire.Next year's awards ceremony will take place in Australia. Registration for Imagine Cup twenty-twelve opened Friday. Also, Microsoft announced plans for a three million dollar program to help Imagine Cup winners further develop their projects.64.Which of the following is true ?A.

According to the above passage, we learn that ________.A.knockoffs can be found in China but not very often.B.the Oxford University Press made the dictionary without outside aid.C.most Chinese editors are also native speakers of English.D.well-educated youth in China’s big cities have difficulty buying houses.69. The possible reason why newer publications updates are not available for book versions is that________.A.book versions can’t keep up with the changes of language.B.the computer network is available everywhere.C.book versions can’t offer a Chinese phonetic pronunciation guide.D.computer technology like the PC and the iPad keeps pace with language.70. What is the main idea of the passage?A.New Chinese terms like ―shanzhai‖ and ―fangnu‖ have got into Oxford Dictionary.B.The latest Oxford English-Chinese, Chinese-English Dictionary is on the market.C.Oxford Dictionary has become more fashionable due to the Chinese language.D.Beijing International Book Fair was where the new Oxford Dictionary was published.第二节(共5小题;每小题2分,满分10分)__71____Painkillers in a tablet can make your headache go away. Antibiotic cream(抗生膏)from a tube can prevent your cuts from becoming infected. But can medicine come packaged in chicken eggs?A team of scientists from Scotland says yes. They've engineered special chickens that lay eggs with disease-treating drugs inside.__72____Animals make thousands of proteins—they’re the main ingredient in skin, hair, milk, and meat. Since animals c an make proteins easily, they’re good candidates for making protein drugs.Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk. But chickens are not expensive to take care of; what’s more, they need less room, an d grow faster than these other animals. ―__73____‖says Simon Lillico of the Roslin Institute near Edinburgh, Scotland.Lillico and a team of researchers changed chickens’ DNA—the code that tells cells how to make proteins so that the birds’ cells made t wo protein drugs. __74____The scientists altered the chickens’ DNA so that the birds made these drugs only in their egg whites (蛋清). This protects the chickens’ bodies from the drugs’ possible harmful effects and makes it easy for scientists to collect the drugs.These special chickens can pass on their drug-laying abilities to their chicks. __75____ The scientists need to improve these chickens before they roost (栖息) in drug companies’ labs. The birds don’t make enough drugs to treat people yet. But on ce the researchers perfect their technique, you might eventually take your medicine sunny-side up.A. Medicine comes in lots of different uses.B. Those qualities could make chickens a better choice to become living drug factories.C. So far, the Scottish researchers have bred five generations of drug—producing birds.D. Some chickens are found having the ability of treating diseases.E. One drug can treat skin cancer, and the other treats a nerve disease called multiplesclerosis(硬化).F. These drugs are made of molecules called proteins.G. Medicine comes in lots of different packages.第二卷(共35分)第四部分:写作(共两节,满分35分)第一节:短文改错(共10小题;每小题1分,满分10分)Recently, as the development of the Internet, there is a kind of language calling Web language. Some people even speak Chinese mixed with English letters. The other day our class had a discussion about if we should welcome the Web Language.Forty percent of the students think it ridiculous. In their opinions, it does no good to help people communicate, nor is it usefu l for learning English. Besides, it’ll make Chinese more standard and pure, finally ruining our mother tongue. However, 69% of our class is fond of it. They think it is simple, convenient and helpful in expressing them. What’s more, it may make the languag e more interesting.Personally, it’s not good habit to use the Web language. It may be popular, but you may also make yourself be misunderstood.第二节:书面表达(满分25分)学校英语论坛对是否需要安装"绿坝——花季护航"软件(the software Green Dam —Y outh Escort)以保证学生健康上网一事展开了一场激烈的讨论。
