Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3,000 feet away straight up. A decade ago, adopting the infrared （紅外線）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (殺蟲劑)spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest(害蟲)problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat sent out by crops. The data were transformed into a color-coded map showing where plants were running “fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide that they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements（改進(jìn)）ininfrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States,” says George Oerther of Texas A& M, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

［1］Today, millions of people want to learn or improve their English but it is difficult to find the best method．Is it better to study in Britain or America or to study in your own country?
［2］The advantages of going to Britain seem obvious．Firstly, you will be able to listen to the language all the time you are in the country．You will be surrounded completely by the language wherever you go．Another advantage is that you have to speak the language if you are with other people．In Italy,it is always possible, in the class, to speak Italian if you want to and the learning is slower．
［3］On the other hand,              staying at home to study．You don’t have to make big changes to your life．As well as this,it is also a lot cheaper than going to Britain but it is never possible to achieve the results of living in the UK．If you have a good teacher in Italy,I think you can learn in a more concentrated way than being in Britain without going to a school．
［4］So,in conclusion,I think that if you have enough time and enough money, the best choice is to spend some time in the UK．This is simply not possible for most people, so being here in Italy is the only（可行的）viable option．The most important thing to do in this situation is to maximise your opportunities:to speak only English in class and to try to use English whenever possible outside the class．

[1] If you are applying for an American higher education, you probably dream of getting into an Ivy League (常青藤聯(lián)盟) university．The eight schools with the best reputations attract top students from the United States and many other countries． However, on average, the Ivy League schools accept less than 15 percent of applicants．And with the applicants growing in size year on year, it is becoming more and more difficult _________．
[2] So how can you give yourself the best chance of admission?
[3]Having a high school grade point average （GPA） in the top 10 percent of your class and being ranked among the top few students dramatically betters your chances．But although GPA and SAT scores are important, they only tell admission deans（主任）part of the story．
[4] The whole admissions process will single out (挑選出) from a large pool of academically strong applicants the unique individuals．They stand out because they have shown in their interviews a range of virtues (優(yōu)點) expected of these universities．Take Harvard for example．Although there is no guarantee of admission, the school judges applicants based on 15 additional criteria．
[5] Intellectual curiosity (求知欲) comes first tor almost all admission deans．Schools look to such students because they believe their peers find them stimulating（激勵人的）inside and outside the classroom．
[6] Leadership also weighs heavily．The school would rather see an applicant who takes on additional responsibility in one or two areas where he or she is good at, rather than one who is merely "very good" academically．This can mean the class presidency（主席職務(wù)）, leading the cheerleading team or being the officer of a student union．
[7] Whether a person has personal warmth and cares about others counts a lot with the admission deans．Writing an essay on a personal experience, like a summer spent raising funds for the earthquake victims or teaching in a local school, can show that a person has qualities in addition to academic experience．
小題1:What is the purpose of the passage? （no more than 15 words）

Read the following passage. Answer the questions according to the information given in the passage.
Indian’s snake charmers are to be retrained as wildlife teachers under a plan to prevent their unique skills and knowledge from being lost. The charmers， who make snakes dance to the sound of flutes， used to be a traditional feature of Indian life， performing in towns and villages， until they were banned in 1972 to control the trade in snake skins.
The government is now considering a plan to train the saperas， as they are known， to visit schools and zoos to tell children about forests and wildlife. There is also a proposal to set up a “dial a snake charmer” service to help householders to deal with unwelcome intruders.
“For generations they have been a feature of Indian life but now they can’t earn a living for fear of arrest，” said Behar Dutt， a conservationist behind the plans， “if a policeman doesn’t catch them， animal rights activists report them.”
Many snake charmers have continued to work clandestinely(暗中地) since the ban， despite the threat of up to three years in jail. But their trademark cloth-covered baskets， hung from a bamboo pole carried across their shoulders， make them an easy target for police.
The fate of Shisha Nath， 56， from Badarpur， a village just outside of New Delhi， is typical of practitioners(從業(yè)者) of the dying art. “I used to earn enough to support my family and send my children to school，” he said. “Now it’s hard to earn even $1 a day. My children want to be snake charmers. It’s our identity. We love the work. But it’s become impossible.”
Next month Dutt’s project to train 30 snake charmers will begin at a snake park in Pune， western India， where experts will enrich their home-grown skills with some formal knowledge.
More than the law， though， it is the dishonest attitude of their fellow countrymen that anger many snake charmers.
“We’re disturbed all the time but when people want a snake removed from the house， they rush to us，” said Prakash Nath， who was ordered recently to the home of Sonia Gandhi， the Congress party leader.
小題1: What do snake charmers usually do in India？ (no more than 8 words) (2 marks)
小題2: How long will a saperas be in prison if he is caught during the ban？ (no more than 3 words) (2 marks)
　
小題3:For what purpose will snake charmers in India be retrained as wildlife teachers？(no more than 10 words) (3 marks)
　
小題4:According to the passage， what will make snake charmers angry？ (no more than 11 words) (3 marks)

[1] When it comes to protecting the privacy of their children，US parents give social networks a failing grade.
[2] Three out of four parents believe social networks are not doing a good job of protecting kids’online privacy. The survey was conducted for Common Sense Media，a nonprofit organization dedicated to helping families surf the world of media and technology. 92 percent of parents said they are concerned that children share too much information online，and 85 percent said they are more concerned about online privacy than they were five years ago.
[3] The poll found a great deal of concern about geo-location services which pinpoint someone’s whereabouts.91 percent of parents said search engines and social networking sites should not be able to share the physical location of children with other companies until parents give authorization.
[4] The results present a clear divide between the industry’s view of privacy and the opinion of parents and kids. Common Sense Media chief executive and founder James Steyer said：“American families are deeply worried about how their personal information is being used by technology and online companies. However， the companies appear to be keeping their heads deep in the sand.”
[5] Technology companies need to step up but parents，children，schools and government also need to do more，he said.“Parents and kids have to educate themselves about             ，”he said.“Schools should teach all students and their parents about privacy protection.

SECTION B (10 points)
Direction: Read the following passage and answer the questions according to the information you get in the passage and the required words limit.
Several years ago, Masaru Ibuka, the chairman of Sony, was at a company planning a meeting. Suddenly he had a brilliant idea. He stopped the meeting and asked everyone present what would happen if Sony removed the recording function and speaker and sold headphones(耳機) with a tape player instead. Almost everyone thought he was crazy. Still, Ibuka kept thinking about his idea and worked at refining it. The result, of course, turned out to be the wildly successful Sony Walkman.
Good ideas often start with a really silly question. Bill Bowerman was making breakfast one day. As he stood there making waffles(蛋奶烙餅)for his son, he wondered what would happen if he poured rubber into his waffle iron(蛋奶烙餅烤模).So, he tried and the result looked something like the bottom of most sports shoes we see today. Still, when he took this idea to several existing shoe companies he was literally(確實地)laughed at. In fact, every single company turned him down. Though rather disappointed, Bowerman was determined and went on to form his own company, making NIKE athletic shoes.
Sometimes good ideas grow out of frustration(挫敗). When Fred Smith was a student at Yale University, he had some paperwork that he needed to have delivered across the country the next day. Smith was amazed to find out that overnight delivery(隔夜送貨) was impossible. He sat for a long while wondering why. Why couldn’t there be reliable overnight mail delivery service? He decided to design one. Smith did just that and turned his design into a class project. His business professor thought it was not a good class project and gave him only a C. However, Smith refined the idea in that class project and eventually turned it into one of the first and most successful overnight mail services in the world——FedEx.

After Mom died, I began visiting Dad every morning before I went to work. He was frail and moved slowly, but he always had a glass of freshly squeezed orange juice on the kitchen table for me, along with an unsigned note reading, “Drink your juice.” Such a gesture, I knew, was as far as Dad had ever been able to go in expressing his love. In fact, I remember, as a kid I had questioned Mom“ Why doesn't Dad love me!” Mom frowned. “Who said he doesn't love you!” “Well, he never tells me,” I complained. “He never tells me either,” she said, smiling. “But look how hard he works to take care of us, to buy us food and clothes, and to pay for this house. That's how your father tells us he loves us.” Then Mom held me by the shoulders and asked, “Do you understand?’’ I nodded slowly. I understood in my head, but not in my heart. I still wanted my father to put his arms around me and tell me he loved me. Dad owned and operated a small scrap（片）metal business, and after school I often hung around while he worked. I always hoped he'd ask me to help and then praise me for what I did. He never asked. His tasks were too dangerous for a young boy to attempt, and Mom was already worried enough that he'd hurt himself. Dad hand fed scrap steel into a device that chopped it as cleanly as a butcher chops a rack of ribs. The machine looked like a giant pair of scissors, with blades thicker than my father's body. If he didn't feed those terrifying blades just right, he risked serious injury. “Why don't you hire someone to do that for you?” Mom asked Dad one night as she bent over him and rubbed his aching shoulders with a strong smelling liniment. “Why don't you hire a cook? ”Dad asked, giving her one of his rare smiles.
Many years later, during my first daily visit, after drinking the juice my father had squeezed for me, I walked over, hugged him and said, “I love you, Dad.” From then on I did this every morning. My father never told me how he felt about my hugs, and there was never any expression on his face when I gave them.
小題1:What would be the best title for the passage?

閱讀下面文章，回答有關(guān)小題，注意括號內(nèi)的詞數(shù)。
Do you have a friend who is upset about his or her parent’s drinking? You want to do something to help, but what? Your friend may not talk about this with you, but you can still be a good friend. One out of four children lives with at least one adult who has alcoholism, so your friend is not alone.
●Be a good listener. Your friend may need someone to talk to. Listen to your friend and suggest that she or he talk to a trusted adult in addition to talking to you .You can offer a good listening ear, but sometimes an adult is needed for more serious things. Maybe you can suggest a caring adult for your friend to talk to, such as a teacher, a neighbor, or a grandparent. He will listen and support your friend, and he will not hurt your friend or put your friend down.
●Don’t spread gossip(閑話) about your friend’s family. It’s okay to tell your parents or another trusted adult what is going on, but respect your friend’s right by not telling other kids in your class.
●Ask your parents if your friend ___________your house, and then invite your friend over for enjoyable activities or to do homework together. Sometimes your friend might just need to get away and have fun being a kid.
●Don’t ride in a car when a friend’s parent has been drinking if you can avoid it. It is not safe. Call your parents, walk, or try to get a ride with an adult you know who has not been drinking. If you must get in the car with a drinking driver, sit in the middle of the back seat with your seat belt fastened. Lock your doors and try to stay calm.

One thing Britain is famous for is pubs, and no trip to the UK would be complete without a visit to one of the thousands of pubs across the country.
Pubs play an important part in the social structure of the country. They are places where all ages and social classes mix to talk, do business, or just spend a couple of quiet hours before heading home in the evening.
There are many different types of beer available in pubs. Traditional British beer is called bitter, or ale, and is usually served at room temperature. As a result, the British are famous for their ‘warm beer’! If you prefer a cold one, ask for lager. This beer is a light yellow in colour whereas bitter is usually a darker brown. All beers are served as pints (500ml) or halves (250ml). To order, you need to ask for a pint or half, and then name the beer. So, you could say “             .”
Wine, red or white, is normally available in all pubs, as are spirits such as whisky, gin or vodka. It is not, however, necessary to drink alcohol. Non－alcoholic drinks are called soft drinks. You can have juice, lemonade or cola, among others.
If you visit a pub in a group, it is important to pay for your ‘round’. This means that you buy a drink for everyone in your group. Not buying your round is a big social mistake! Remember that you need to order and pay for your drinks at the bar.
So, follow these tips if you want to get the most out of visiting a pub, and, “cheers!”
