Still want a laptop? That was so yesterday. Get ready for the next stage in the personal computer revolution: It's the ultrathin (超薄的), cheap netbook.
According to a New York Times report last week, personal computers are about to go through their biggest change since the rise of the laptop. By the end of the year, consumers are likely to see laptops the size of thin paperback books that can run all day on a single charge and are equipped with touch screens or slide-out keyboards. The netbook is a kind of portable computer with learner functions for online surfing and basic computing activities, for example, word processing. To cut the cost and weight, they usually have a low-powered processor, small screen, narrow keyboard, and no ODD.
Currently, some of the devices look more like a toy than a full-feature computer. That's because most of the netbooks sold today run on an Intel chip called Atom. This is a lower-power version of the company's standard laptop chip, so they have trouble running demanding software like games and photo-editing programs.
This year, a group of companies who make cheap, power-saving chips used in cell phones are applying that expert skill to PCs. That means they will break Atom's netbook dominance (統(tǒng)治地位) and reduce the size while letting it run complicated programs.
The big winner in the rise of netbooks will be the consumer. AT&T announced last week that customers in Atlanta, Georgia, US, could get a netbook for just $50 (342 yuan) if they signed up for an Internet service plan. This trend will soon spread to Asia, according to industry experts.
University campuses are a major target of Shanzhai netbooks—uncopyrighted (無版權(quán)的) domestic copies of foreign brands. These products are usually sold at less than 2,000 yuan. But industry insiders suggest students not use these nameless products because many of them don't provide good after-safes services.
49.The following are all advantages of netbooks EXCEPT that      .
A.people can easily edit photographs with them
B.they cost less than other personal computers
C.they are very thin and easy to carry
D.they save power
50.Why are students advised not to use Shanzhai netbooks?
A.Because they are of poor quality.
B.Because they are not easy to operate.
C.Because they will soon be out of date.
D.Because they lack good after-sales services.
51.What can be inferred from the passage?
A.Laptops are becoming more and more popular.
B.University students seldom buy Shanzhai netbooks.
C.Shanzhai netbooks are sold better than those of famous foreign brands.
D.Atom's netbooks make up the largest part of the sales of portable computers at present.
52.What is the general idea of this passage?
A.Shanzhai netbooks are taking control of laptop market.
B.Netbooks have advantages over laptops in everything.
C.Netbooks are becoming the trend of personal computers.
D.Most of the netbooks sold today run on an Intel chip called Atom.

“A good book for children should simply be a good book in its own right,” says Mollie Hunter. Born and brought up near Edinburgh, Mollie has devoted her talents to writing primarily for young people. She firmly believes that there is always and should always be a wider audience for any good book whatever its main market is. In Mollie's opinion it is necessary to make full use of language and she enjoys telling a story, which is what every writer should be doing. “If you aren't telling a story, you're a very dead writer indeed,” she says. With the chief function of a writer being to entertain, Mollie is indeed an entertainer. “I have this great love of not only the meaning of language but of the music of language,” she says. “This love goes back to early childhood. I've told stories all my life. I had a school teacher who used to ask us what we would like to be when we grew up and, because my family always had dogs, and I was very good at handling them, I said I wanted to work with dogs, and the teacher always said ‘Nonsense, Mollie, dear, you’ll be a writer.’ So finally I thought that this woman must have something, since she was a good teacher and I decided when I was nine that I would be a writer.”
This childhood intention is described in her novel, A Sound of Chariots, which although written in the third person is clearly autobiographical and gives a picture both of Mollie's ambition and her struggle towards its achievement. Thoughts of her childhood inevitably(不可避免地)brought thoughts of the time when her home was still a village with buttercup meadows and strawberry fields—sadly now covered with modern houses.“I was once taken back to see it and I felt that somebody had lain dirty hands all over my childhood. I'll never go back,”she said. “Never.”“When I set one of my books in Scotland,”she said,“I can recall my romantic (浪漫的) feelings as a child playing in those fields, or watching the village blacksmith at work. And that's important, because children now know so much so early that romance can't exist for them, as it did for us.”
57. What does Mollie Hunter feel about the nature of a good book?
A. It should not aim at a narrow audience.
B. It should not be attractive to young readers.
C. It should be based on original ideas.
D. It should not include too much conversation.
58. In Mollie Hunter's opinion, which of the following is one sign of a poor writer?
A. Being poor in life experience.        B. Being short of writing skills.
C. The weakness of description.           D. The absence of a story.
59. What do we learn about Mollie Hunter as a young child?
A. She didn't expect to become a writer.         B. She didn't enjoy writing stories.
C. She didn't have any particular ambitions.   D. She didn't respect her teacher's views.
60. What's the writer's purpose in this text?
A. To describe Mollie Hunter's most successful books.
B. To share her enjoyment of Mollie Hunter's books.
C. To introduce Mollie Hunter's work to a wider audience.
D. To provide information for Mollie Hunter's existing readers.

One of the main challenges facing many coutries is how to maintain their identity in the face of globalization and the growing multi-language trend. “One of the main reasons for economic failure in many African countries is the fact that,with a few important exceptions,mother-tongue
education is not practiced in any of the independent African states." said Neville Alexander.Dutctor of the Project for the Study of Aitemative Education in South Africa at the  University of Cape Town.
In response to the spread of English and  the increased  multi-language trends arising from Immigration . many countries have inuoduced language laws in the laws in the last decade .In some ,the use  of languages other than the national language is banned in public spaccs such as advertsing  posters.  One of the first such legal proviaions was the  1994  " Toubon law'  in France. but the idea hs been copied in many counuics since then. Such efrorts to govern language use are often
dismisscd as futile by language experts . who are well aware of the difficulty of controlling fashions in specch and know  from research  that language switching among bilinguals is a natural process.
It is especiaLly difficult for native speakers of English to understand the desire to maintain the 'purity" of a language by law.  Since the time of Shakespeare . English has continually absorbed
foreign words into its own language. EngLish is one of the most mixed and rapidly changing languages in the world. But the  has not been a barrier to acquiring prestige and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it bas never been the Aryllo-Saxon way of doing things. English has never had a state-controlled
autharity for the language,  similar, for example . to the Academie Francaise in France.
The need to prorect national languages is for most western Europeansa recent phenomenon- especially the need to ensure that English does not unnecessarily take over too many fields.
Public communication, educauon and new modcs of communication promoted by technology,may be key fields to defend.
46. Neville Alexander believes that___________.
A. mother-tongue education is not practiced in all African countries
B. lack of mother-tongue education can lead to economic failure
C. globalization has led to  the rise of multi-language trends
D. globalization has resulted in the econonuc failure of Africa
47 .  The underlined word " futile"   (in paragraph 2)  most probably means "___________"     
A. useless     B. pracucal     C. workable     D. unnecessary
48. Why do many English-speaking; cuuntries not support the language protection efforts described  in the passage?
A. They think language protection laws are ineffective.
B. They want their language to spread to other countries.
C. They have a long history of taking words from other languages.
D. It reduces a language's ability tO acquire intenatiunal importance.
49.what  can we infer from the last paragraph?
A. English has taken over fields like public communication and education.
B. Europeans have long realizcd the need to protect their national Languages.
C. Most language experts believe it is important to promote a national language.
D. Many aspects of national culture are threatened by the spread of English.
50.  The best title for the passage is___________.
A. Fighting against the rule of English

閱讀下列短文,從每題所給的A、B、C和D項中,選出最佳選項,并存答題卡上將該
項涂黑。
(A)
Increasingly over the last few years,we have become familiar with the range of small electronic devices or  “smart” accessories (附件,飾品 ) . Pocket heart -rate monitors for joggers and electronic maps are just the first examples of many new products that promise to change our lives in all sorts of surprising ways.
As a scientist at New York University . Rosalind Picard tries out different smart accessories before they go on the market.  One of these was the so-called " frown (皺眉)headband". Rosalind was shocked to realize just how often she frowned. Stuck in a traffic jam recently, Rosalind kept hearing the sounds of the tiny sensor inside the band worn around her forehead -each time she frowned in annoyance, the sensor gave out a signal.
Another computer scientist , Stevcn Feiner, is working on a pair of glasses that will do more than help you to see .Imagine you want to try a restaurant in a foreign city but you're not familiar with the dishes on the menu.  If you are weanng a pair of Steven's glasses . all yau have to do is glance above the restauran’s doorway and your glasses will immediately become windows to the Tntemet, offering you full details of the meals served inside. The glasses could also be used to help people make speeches,give chefs access to the latest recipes and even provide doctors with
patient information while they carry out operations.
At the moment, Steven's invention looks more like a large ski mask than a pair of glasses.
It's a headset connected to a hand-held computer and a Global Positioning  System  ( GPS ) receiver, which tracks the wearer's position. But he says that these head-worn displays will eventually get smaller and lighter as technology improves.
And, of course, this new technology has a fashionable as well as a useful application. A chemical engineer named Roben Langer has invented a new microchip that, if put inside a ring,can give off different smells according to a person's mood. That, of course, may or may not appeal to you.  And,in the end , it is  shoppers . not scientiscs , who will determine which of these smart accessories will succeed as fashionable items and which are sure tO join history's long list of crazy inventions.
It is clear,however ,that as computers get smaller and cheapcr.  Lhcy will pop up in all sorts
of easily-wearable accessories . even in the buttons on your coat.  WhaCs morc, this is something that's going to happen a lot sooner than we all expect.
41. When Rosalind wore the headband, she was surprised a___________
A. how well the sensor worked           B. how she was affected by traffic
C. how strong the signal was            D. how uncomfortable it was
42.  For people eating out , Steven’ s glasses can___________      
A . give them a restaurant's location
B.  let them see a restaurant's environment
C.  inform them about a restaurant’s menu 
D.  tell them about a restaurant's quality
43. What is the current problem with Stevcn's glasses?
A. Limited function.                B. Inconvenience.
C. High cost.                       D. Poor Internet access.
44.  In general, what does the writer think about smart accessories?
A. They will soon be widely available.
B. Much more research is needed into them.
C. Only a few of them will appeal to shoppers.
D. Most of them are considered to be crazy inventions.
45. What's the writer's purpose in writing this passage?

C
Recently scientists have worked out a way to judge roughly where a person has lived using strands(縷) of hair, a technique that could help track the movements of criminal suspects or unidentified bodies .
The method depends on measuring how chemical variations in drinking water show up in people’s hair.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as clouds move.
Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid(列陣)falls first. As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can establish a geographic timeline. Each inch of hair corresponds to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a frame of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops. They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems. 
“It’s not good for pinpointing (精確定位),” he said. “It’s good for ruling out many possibilities.”
64. What can we learn from the passage about the latest discovery?
A. One’s hair growth has to do with the amount of water they drink.
B. A person’s hair may reveal where they have lived.
C. Hair analysis identifies criminal suspects accurately.
D. The chemical composition of hair varies from person to person.
65. What does the underlined word “identical” in paragraph 3 probably mean?
A. similar                        B. fantastic                C. beneficial              D. healthy
66. What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.

第三部分 閱讀理解(共15小題;每小題2分,滿分30分)
閱讀下列短文,從每題所給的四個選項(A、B、C和D)中,選出最佳選項。
A
The iPad, a new e-tablet gadget will take online activities truly mobile. It will allow you to read the news in bed, play multiplayer game on any surface, check a recipe in a busy kitchen or view a large-scale Google map.
It will declare a new age of online media production, taking newspapers and magazines down the new stage. Online versions can now become truly interactive. The editor of Time magazine Richard Stengel said, “The iPad will transform the way journalism works. It will become a new way of storytelling”.
Perhaps most important to the masses, it is a traditional computer but so convenient to use. There are no cords(電線), and it’s totally mobile. You press a button and it comes on in seconds. To add a program, you just download it from the Internet. There is no file directory, so you won’t be confused with file locations.
Since almost everyone uses a computer in the office or at school, the need for the traditional desktop model at home is disappearing. Slate Magazine’s Farhad Manjoo calls the iPad the perfect alternative to the full home computer system.
However, opinions are summarized as a simple statement: If you are a tech-head you will hate it, if you are everyone else you will love it. It’s “l(fā)aughably absurd” on one blog and a “magical revolution” on another.
This first version of the iPad lacks many basic features. Tech-heads dislike the device not because of what it offers, but because of what it doesn’t offer. It doesn’t have flash or a camera. It can’t access many of the world’s mobile applications, and it has a very restricted APPLE store. Based on purely technological grounds, the iPad is said to lack more than it gives.
But if you are not part of the technologically well-versed, and you love the iPod and iPhone, “this device is for you,” said Steve Jobs, Apple’s CEO.
But no matter how you feel about the iPad, as a tech-head or an everyman, there’s no arguing with its appeal. Love it or hate it, the iPad sold over 600,000 units on its opening weekend, surpassing(超過) the iPhone’s record sales in 2007.
It’s uncertain how long it will take to hit the tech markets here in China, but when it does, expect the iPad fashion to continue. Apple predicts it will sell over 7.1 million units in the first year. Maybe not magical, and definitely not absurd, but if the iPad follows in the footsteps of the iPhone and iPod, you could be reading this newspaper on it in the near future.
56. Which of the following is NOT the reason why people think the iPad a “magical revolution”?
A. The iPad will make online activities truly mobile.
B. The iPad will predict a new age of online media production.
C. The iPad is sure to take the place of the full home computer system.
D. The iPad can make many world’s mobile applications accessible.
57. Which of the following statements is false according to the passage?
A. Unlike those traditional computers, the iPad can save you much trouble.
B. The iPad set up a new record sale when it first came onto the market.
C. The iPad will probably hold a big share in the tech market in China.
D. The iPad depends on cords to download a program from the Internet quickly.
58. What technological problem do experts think the iPad has?
A. The iPad is lacking in what other computers can offer.
B. People might misunderstand its magical features.
C. Reporters and journalists don’t have to efficiently with the help of the iPad.
D. Compared with the iPhone and iPod, iPad might confuse the users more easily
59. Which of the following would be the best title for the passage?
A. Why do People Love the iPad            B. The Popularity of the iPad
C. Loving and Hating the iPad                     D. A Magical Revolution

C
Poorer children would be offered the chance to attend lessons on Saturday to help catch up with their middle?class peers (同齡人), the shadow schools secretary, Michael Gove, said today.?The Conservatives would give English state schools the freedom to choose to have longer teaching hours and extra classes at the weekend, he told the Association of Teachers and Lecturers’annual conference.?
Gove said the move would help to close the achievement gap with richer children whose parents could afford extras such as tutoring and music lessons.?
He told delegates (代表) in Manchester: “For children who come from homes where parents don’t have the resources to provide additional stretch and cultural experiences, there are benefits in having those children in the learning environment, in school, for longer.”?
“Parents would love to have schools starting earlier in some circumstances, and certainly going on later in the afternoon, given the reality of their working lives,” he said. He held up the example of Kipp (Knowledge is Power Program) schools in the US, which are often based in the poorest communities and open from 7:30 am to 5pm on weekdays, plus Saturdays.?
But it would be up to schools to decide to offer longer hours, Gove added. ?
Parents said Saturday classes could become a “badge of dishonor”if pupils were forced to go, while teachers raised concerns about their workload.?
Margaret Morrissey, of Parents Outloud, said: “I think the suggestion the government made about one-to-one teaching for these kids would be a more preferable way of improving these children’s performance. I’m just not sure whether taking away a child at weekends is actually going to make them cleverer in the week.”?
The ATL’s general secretary, Mary Bousted, said: “If we want Saturday schools, then we need more teachers doing the extra hours, not the same teachers working longer.”?
66. The program is intended for children____________. ?
A. who are from middle-class families?     B. whose parents can’t afford extra help ?
C. who perform poorly academically ?      D. whose weekends are mostly unoccupied
67. “Additional stretch” in Paragraph 4 probably refers to_________.?
A. music lessons                  B. physical relaxation ?
C. entertainment activities?        D. out-of-school improvement
68. Why did Gove mention Kipp schools in the US? ?
A. To make a comparison.?         B. To introduce a new program.?
C. To seek supportive evidence.?     D. To prove his program is better.
69. What is Margaret Morrissey’s opinion about the new program? ?
A. Favourable.          B. Doubtful.           C. Optimistic.         D. Acceptable.
70. Which of the following is true??
A. Teachers may not like the program. ?   B. Schools are trying to make profits.?

B
Across the United States, there are several places where two independent towns grew together to become one city — but kept both their names.
Winston?Salem is one of them. It’s a mid?sized city in what’s called the plateau(high land), between the Atlantic Coast and the inland mountains in the state of North Carolina. The Winston part is a relatively new place, founded early this century. It’s home to the nation’s biggest open?air tobacco market.?
The giant R.J. Reynolds Tobacco Company’s headquarters is in Winston?Salem, and Winston is the name of one of Reynolds’best?known cigarette brands. Fast?growing Winston soon surrounded the much older town of Salem, so in 1913, people in the area voted to combine them into a single place.?
From a historical and tourist point of view, Salem, or Old Salem, as it’s called today, is the interesting and unusual part of town.?
Salem was founded in the 1700s by the Moravians. They spoke German, and their community was religiously based, with single men and single women living apart in separate dormitories. The Moravians greatly valued women’s work and brainpower. In fact, one of the nation’s oldest boarding schools for young women— the Moravians’Salem Academy founded in 1772 — is still in operation. ?
Over the years, Salem lost its Moravian character. That all changed, though, when a nonprofit group began to rehabilitate the historic area. These days Old Salem is what’s called a living history museum, with exhibits, music, and tours of 18th-century houses, taverns and Moravian dormitory buildings just seven blocks from the tallest skyscraper in Winston-Salem.?
The historic community is booming again. Just as R. J. Reynolds is taking in millions of dollars making cigarettes across town, Old Salem is generating about S| 15 million a year in tourism revenue and donations.?
61. From the passage we can know that____________.?
A. Winston-Salem is the name of a city?
B. Salem is home to the tobacco market?
C. the city Winston-alem has two names?
D. Old Salem is the name of a tobacco brand
62. It can be inferred from Paragraph 3 that__________.?
A. the two cities benefited each other?
B. Salem developed faster than Winston?
C. R.J. Reynolds Company has moved into Salem?
D. the combination meets the wishes of the people
63. The city Salem is special for its__________.?
A. boarding school                          B. lifestyle and tradition?
C. respect for brainpower                    D. religious belief
64. The underlined word “rehabilitate” in Paragraph 6 is closest in meaning to “_________”.?
A. reconstruct            B. evaluate         C. enlarge         D. decorate?
65. What will probably be talked about in the following part? ?
A. Some other attractions in Winston-Salem. ?
B. How Winston makes profits from tourism. ?
C. Other examples of cities combined by two parts.?
D. Something about the boarding school for women.

London: What could possibly he wrong with planting trees? The benefits are obvious: they firm the soil, absorb extra water and take carbon dioxide out of the atmosphere.
However, it now turns out that planting trees could add to global warming. Tree roots do a great job of keeping soil firmly on the ground and out of the wind's power. The problem is that some of those dust clouds play an important part in taking in carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting program there is successful and the dust supply reduced, the final result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work shows clearly the complexity of the system and the importance of not working uselessly with it without understanding the results. For this reason the need is to focus on cutting carbon dioxide giving off rather than dealing with the land surface aimlessly.
An American scientist, Robert Jackson, has shown that when native grassland areas are occupied by trees, carbon is lost from the soil. "We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees. " said Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed by the loss of carbon from the soil below ground.
Countries that plan to combat global warming by planting trees may have to think again. Solutions to environmental problems are often more complex than they first appear, and understanding the Earth's climate is a very great challenge.
64. People usually hold the opinion that _______.
A. huge dust storms can destroy carbon dioxide
B. huge dust storms can destroy the oceans on the earth
C. planting trees could reduce global warming
D. planting trees is the only way to control huge dust storms
65. Andy Ridgwell, the environmental scientist, believes that _______.
