Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and then, after a full day of work, going back home to Beijing and having dinner there.
Sounds unusual, doesn't it? But it's not that unrealistic, with the development of China’s high—speed railway system. And that’s not all. China has an even greater high-speed railway plan—to connect the country with Southeast Asia, and eventually Eastern Europe.
China is negotiating to extend its own high·-speed railway network to up to 17 countries in 10 to 15 years, eventually reaching London and Singapore.
China has proposed three such projects. The first would possibly connect Kunming with  Singapore via Vietnam and Malaysia. Another could start in Urumqi and go through Kazakhstan and Uzbekistan, and possibly to Germany. The third would start in the northeast and go north through Russia and then into Western Europe.
If China’s plan for the high-speed railway goes forward, people could zip over from London to Berlin in under two days.
The new system would still follow China’s high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes.
China’s bullet train(高速客車),the one connecting Wuhan to Guangzhou, already has the   World’s fastest average speed. It covers 1,069 kilometers in about three hours.
Of course, there are some technical challenges to overcome. There are so many issues that need to be settled, such as safety, rail gauge(軌距),maintenance of railway tracks. So, it’s important to pay attention to every detail.
But the key issue is really money. China is already spending hundreds of billions of yuan on domestic railway expansion.
China prefers that the other countries pay in natural resources rather than with capital  investment. Resources from those countries could stream into China to sustain development.
It’ll be a win-win project. For other countries, the railway network will definitely create more opportunities for business, tourism and so on, not to mention the better communication among those countries.
For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China’s far west. We foresee that in the coming decades, millions of people will migrate to the western regions, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west once and for all. And they’11 trade with Central Asian and Eastern European countries.
小題1:China’s new high-speed railway plan will be a win-win project because     .
A．China will get much-needed resources and develop its western regions
B．China and the countries involved will benefit from the project in various ways
C．China will develop its railway system and communication with other countries

Most people believe they don’t have much imagination. They are    11   . Everyone has imagination, but most of us, once we become adults, forget how to   12  it. Creativity isn’t always  13 with great works of art or ideas. People at work and in their free time   14   think of creative ways to solve problems. Maybe you have a goal to achieve, a tricky question to answer or you just want to expand your mind! Here are three techniques to help you.
　　Making connections. This technique involves taking   15  ideas and trying to find links between them. First, think about the problem you have to solve or the job you need to do. Then find an image, word, idea or object, for example, a candle. Write down all the ideas/words  16  with candles: light, fire, matches, wax, night, silence, etc. Think of as many as you can. The next stage is to relate the   17 to the job you have to do. So imagine you want to buy a friend an original   18  ; you could buy him tickets to match or take him out for the night.
　　NO limits! Imagine that normal limitations don’t   19  . You have as much time /space / money, etc. as you want. Think about your goal and the new  20  . If your goal is to learn to ski,    21  , you can now practise skiing every day of your life (because you have the time and the money). Now   22   this to reality. Maybe you can practise skiing every day in December, or every Monday in January.
Be someone else! Look at the situation from a    23  point of view. Good businessmen use this technique in trade, and so do writers. Fiction writers often imagine they are the  24   in their books. They ask questions: What does this character want? Why can’t she get it? What changes must she make to get what she wants? If your goal involves other people, put yourself in their    25 .

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough，the answer to both these questions is yes. To some extent（程度）our intelligence is given to us at birth，and special education can never make a genius(天才) out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of a person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts can be supported in a number of ways.
It is easy to say that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different. If on the other hand we take two identical twins, they  will very likely be as intelligent as each other. Relations like brothers and sisters，parents and children，usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine that now we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence.
小題1:By using the example that two people closer in blood relationship are closer in intelligence that writer wants to prove    _    .
A．intelligence can be developed by environment
B．intelligence is given at birth
C．intelligence can be developed by experience
D．education plays an important part in the development of education
小題2:A child who lives in rich and varied surroundings turns out higher in intelligence because ________.
A．his family is rich and therefore can afford to develop his intelligence
B．he can break the limits of intelligence fixed at birth
C．his family is rich and provides him with various healthy food
D．these surroundings are likely to help him reach the limits of their intelligence
小題3:In the second paragraph “if we take two unrelated people at random from the population．．．” means “if we ____．”
A．choose two persons who are relative
B．take out two different persons
C．choose two persons with different intelligence
D．pick any two persons
小題4:The best title for this passage might be __________.        
A．Birth and EnvironmentB．Intelligence
C．The Answer to a QuestionD．Intelligence and Education

Researchers at the University of Bedforshire have developed a new technique for powering electronic device（裝置）. The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio（無(wú)線電） waves as power.
Believed to be a world first, the team claims it could eventually eliminate (or get rid of )the need for conventional batteries. The university has now filed a patent application to secure the only rights to the technique.
Professor Allen and his team have created a system to use medium wave frequencies to replace batteries in small everyday devices like clocks and remote controls.
The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”. Professor Allen said that as radio waves have energy―like light waves, sound waves or wind waves―then, in theory, these waves could be used to create power.
“The emerging（新興的）area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said. “It’s really exciting way of taking power from sources other than what we would normally think of.”
The team is now waiting for the results of the patent application to secure recognition of the technique. Professor Allen said that the team’s achievements had all been done in their “spare time”. “Our next stage is to try and raise some real funds so that we can take this work forward and make a working prototype（模型）and maybe partner up with the right people and take this to a full product in due course,” he said.
“Power harvesting has a really important part in our future, because, just in this country, we dispose of somewhere between 20,000 and 30,000 tonnes of batteries in landfill（垃圾填理）sites every single year－that is toxic chemicals going into the ground.”
He added that development of the product could also be “commercially beneficial”. “The market for this is several billion pounds. We’ve seen market predictions for 2020 which have these kinds of figures, so there’s a lot of commercial potential in this area,” he said.
Pro-Vice Chancellor at the University of Bedfordshire, Professor Carsten Maple, said, “This type of work is a reflection of the university’s growing reputation and experience in conducting innovative（創(chuàng)新的）research.”
小題1:From the text we know the new technique for powering electronic devices_____.
A．can be applied to all electronic devices.
B．uses radio waves to create power.
C．has replaced conventional batteries.
D．produces many toxic chemicals.
小題2:According to Professor Allen, power harvesting technology______.
A．makes every use of radio waves.
B．takes power from usual sources.
C．reduces our dependency on conventional batteries.
D．a(chǎn)ims at huge commercial benefits.
小題3:What can we learn about Professor Allen and his team from the text?
A．They have made use of radio waves in their daily life.
B．They have raised a big fund to support their research.
C．They have gained a patent for their new technology.
D．They mainly did their research in their spare time.
小題4:What is Professor Carsten Maple’s attitude toward the new technique?
A．Critical.B．Favorable.C．Conservative.D．Negative.
小題5:What is the text mainly about?
A．A new technique to create power.
B．A crisis concerning conventional batteries.
C．Some special sources of power.
D．The development of power harvesting.

The Human Genome(基因組) Project, a great $3 billion, 15-year task aimed at drawing the genetic map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延長(zhǎng))human life. But those communities and policy makers are also careful about the scientific door they are opening as the project uncovers the mysteries of life.
For the last few years, the genetic advances in the fast developing field of biotechnology have provided material for all kinds of work, but the developments of modern science in unlocking the secrets of human genetic code have opened a world of possibilities for human health, as well as for the population imagination.
While European and Japanese researchers are making rapid progress in decoding human DNA, the leading organization for genetic research in the Untied States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with as yet terrible diseases, and making progress toward separating the genes that show a sign of breast cancer(乳腺癌)or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.
小題1:Why did the scientists work so hard at mapping the human genome?
A．Because the human genome can destroy many illnesses.
B．Because the human genome’s completion can help to get rid of many diseases.
C．Because they wanted to be better known than others.
D．Because the Human Genome Project can provided a lot of chances of work.
小題2:According to the passage, which of the following countries is the most advanced in genetic research?

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds (揮發(fā)性化合物) —— chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from such volatile compounds to attract insects such as bugs and bees.
Plants can also discover  volatile compounds produced by other plants. A tree under attack by hungry insets, for instance, may give off these chemicals in order to let other trees know about the attack. In response, the other trees may send off their chemicals to keep the bugs away —— or even chemicals that will attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical sensor (傳感器) called an “electronic nose”. The “e-nose” can tell such compounds as plants make. When plants are attacked, scientists say, the e-nose could help quickly decide whether plants are being eaten by insects. But today, the only way to spot such insects is to inspect individual plants by observing them. This is a challenging task for managers of greenhouses, including those that can house thousands of plants. The research team is working with an e-nose that can recognize volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds based on the interactions (相互作用), and then the e-nose will give off electronic signals that the scientists can analyze by using computer software.
To test the e-nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all being common greenhouse crops. Then scientists collected samples of the air around damaged leaves from each type of crop. These plants had been damaged either by insects or by scientists who made holes in the leaves with a hole punch (打孔器).
The e-nose, it turns out, can identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage —— by insects or with a hole punch —— had been done to the tomato leaves.
With some fine-tuning (微調(diào)), a device like the e-nose can one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this can also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, India, who studies smells of flowers and plants. Hopefully, scientists believe, the device can bring large benefits to greenhouse managers in the near future.
小題1:We learn from the text that plants communicate with each other by ______.
A．making some sounds
B．waving their leaves
C．producing some chemicals
D．sending out electronic signals
小題2:What did the scientists do to find out if the e-nose worked?
A．They fixed 13 sensors inside the device.
B．They presented it with all common crops.

If California were not already so famous for Sillicon Valley(硅谷) and Hollywood, it might be well－known for the groups of water－technology firms in its San Diego County. The reverse－osmosis (RO) spiral module, the technique that supports turning seawater and waste－water into drinkable stuff, began in San Diego in 1964. Today dozens of firms in the area supply many of the world's approximately 13，000 RO plants in places from the Persian Gulf and Israel to Australia and China.
Southern California itself, however, has not so far been a big user of its own technology. This is surprising, given that the whole American south－west faces a water problem. But now as the climate gets warmer and the population increases, there is more agreement that the existing infrastructure, consisting of vast pipes that carry water from the Sacramento Delta in the north and the Colorado River in the east, will not be enough. In places such as San Diego, which has inadequate and salty groundwater and currently imports 90% or its water, the answers must be greater conservation, reusing as much water as possible, and getting most of the rest from the sea.
The first part, conservation, has been widely accepted by the public. San Diego today uses less water with a larger population than it did in 1989, the year water consumption peaked. The second part, water recycling has been a hard sell, because of an unpleasant factor. Americans still use the term “toilet－to－tap” for recycling, even though properly treated waste－water is nowadays completely clean. Singapore made its programme acceptable in part by renaming it as NEWater.
This is where desalination comes in, which means taking the salt out of salt water. A firm called Poseidon Resources is now close to building the biggest desalination plant in America behind a power station by the beach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling, so Poseidon plans to change 104m gallons a day by using the RO spiral module.
Lots of people like the idea. Once fully running in 2015, the plant could produce 10% of the region's water. And there are plans for more desalination plants. Many places would need to take much less water from the endangered Colorado River. But a few people hate it a lot. Joe Geever, an expert in biology, says desalination uses too much energy and that Poseidon plant would kill too much sea life. He understands that there is a role for desalination, he says, but would rather not have it right there, right now, and on this scale.
小題1:Which of the following is WRONG about the RO spiral module according to the passage?
A．This technology is not widely used in its birthplace.
B．Today there are about 13，000 RO plants in the Persian Gulf, Israel, Australia and China.
C．This technology can be used in desalination plants to make sea water drinkable.
D．It is a promising water treatment technology welcomed by a lot of people.
小題2:How many solutions to the water problem in San Diego are mentioned in the article?
A．2.B．3.C．4.D．5.
小題3:What can we infer from the article?
A．The Colorado River is the main water source for California.
B．Americans still use the term “toilet－to－tap” for recycling water.
C．NEWater serves as a brand for recycled clean water in Singapore.
D．Poseidon Resources stands for the power station by the beach in Carlsbad.
小題4:What is Joe Geever's attitude toward building a large desalination plant at present?
A．Supportive.B．Negative.C．Optimistic.D．Vague.
