According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year．Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom．An experiment under way off the coast of Norway, however, could help put them anywhere．
The project, called Hywind, is the world’s first large-scale deepwater wind turbine (涡轮发电机)．Although it uses a fairly standard 152-ton, 2．3-megawatt turbine, Hywind represents totally new technology．The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently．The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves．Hywind’s stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power．If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September．
To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean．To make that turbine heavier, the whole spar’s center of gravity must be moved much closer to the ocean’s surface．To do that, the company plans to design a new kind of wind turbine, one whose gearbox (变速箱) sits at sea level rather than behind the blades．
Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large．Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted．Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection．If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available．The Hywind project uses totally new technology to ensure the stability of_________.
| A．the cables which tie the spar to the ocean floor |
| B．the spar which is floating in deep-sea water |
| C．the blades driven by strong and steady sea wind |
| D．the stones filled in the spar below the sea surface |
To balance a bigger turbine high on a floating spar, a new type of turbine is to be designed with its gearbox sitting_________.
| A．on the sea floor |
| B．on the spar top |
| C．at sea level |
| D．behind the blades |
Wide applications of deepwater wind power technology can_________.
| A．solve the technical problems of deepwater windmills |
| B．make financial profits by producing more turbines |
| C．settle the arguments about environmental problems |
| D．explore low-carbon power resources available at sea |
第三部分：阅读理解(共20小题；每小题2分，满分40分)
阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
Many people often say there is more stress (压力) in today's society than in years past. In fact, these people are comparing our lives with that of the cave man, who didn't have to worry about the stock market or the atomic bomb. They forget that the cave man worried about being eaten by a bear while he was asleep, or about dying of hunger--things that few people worry much about today.
Actually stress is a normal state of affairs, and it's important that people understand what they are talking about when they speak about stress. Whenever anyone experiences something unpleasant, for lack of a better word they say they are under stress. Yet there is such a thing as pleasant stress--as in the case of the Olympic winner at the moment of his glory, or a conductor as his orchestra(乐队) performs particularly well. They are just sending out excitement, and they are giving off all the stress hormones(荷尔蒙)exactly the same as if they were in low spirits or had just heard of a death in the family. We call the pleasant or healthy kind "eustress” and the unpleasant or unhealthy kind "distress".
Then how can people deal with stress? The secret is not to avoid it but to "do your own thing". It implies doing what you like to do and what you are made to do at your own speed. For most people, it is really a matter of learning how to live and how to behave in various situations, to decide: “Do I really want to take my father's business or be a musician?” If you really want to be a musician, then be one.
1. What can be inferred from the first paragraph?
A. Modern people experiences more stress than the cave man.
B. The cave man experienced more stress than modern people.
C. People don't suffer more stress today; it's just that they think they do.
D. Modern people have the same worries as the cave man did.
2. In which of the following situations will you feel "eustress"?
A. Your favorite football team has lost an important game.
B. You have failed an important examination.
C. You are informed of an accident of your best friend.
D. You have won the first prize in an English competition.
3. The purpose of writing the passage is to let us know
A. stress does not necessarily refer to unpleasant experience
B. distress is what people call the pleasant kind of stress
C. an Olympic winner feels the same stress as one who loses a family member
D. people will feel eustress and distress at the same time
4. According to the passage, how can people deal with stress?
A. Do things that you really want to do.
B. Do whatever you're expected to do.
C. Try to do things successfully.
D. Refuse to do whatever you're told to.
Fear and its companion pain are two of the most useful things that men and animals possess, if they are properly used. If fire did not hurt when it burnt, children would play it until their hands were burnt away. Similarly, if pain existed but fear did not, a child would burn itself again and again, because fear would not warn the child to keep away from the fire that had burnt him or her before. A really fearless soldier-and some do exist –is not a good soldier because he is soon killed; and a dead soldier is of no use to his army. Fear and pain are therefore two guards without which men and animals might soon die out.
In our first sentence we suggested that fear ought to be properly used. If, for example, you never go out of your house because of the danger of being knocked down and killed in the street by a car, you are letting fear rule you too much. Even in your house you are not absolutely safe: a plane may crash on your house, or ants may eat away some of the wood in your roof, and they later may fall on you, or you may get cancer !
The important thing is not to let fear rule you, but instead to use fear as your servant and guide. Fear will warn you of dangers; then you have to decide what action to take.
In many cases, you can take quick and successful action to avoid the danger. For example, you see a car coming straight toward you; fear warns you, you jump out of the way, and all is OK.
In some cases, however, you decide that there is nothing that you can do to avoid the danger. For example, you cannot prevent a plane from crashing into your house, and you may not want to go and live in a desert where there are no plants. In this case, fear has given you its warning; you have examined it and decided on your course of action, so fear of this particular danger is no longer of any use to you, and you have to try to overcome it.
1. Children would play with fire until their hands were burnt away if _______.
A. they were given no warning beforehand
B. they didn’t have any sense of pain at all
C. they had never burnt themselves
D. they felt afraid of the fire
2. A really fearless soldier _______.
A. is of a little use to his army

A. they are warned of the danger and take quick action
B. they are quick both in mind and in action
C. they are calm in face of danger
D. they have gained much experience
4. It is implied but not stated that _______.
A. fear is always something helpful
B. too much fear is harmful
C. fear should be used as a servant and guide
D. fear is something strange and particular
Scientists are working to develop crop plants that can reduce the amount of water used for agriculture. Almost sixty percent of the world’s freshwater withdrawals from rivers, lakes and other water resources go toward irrigating fields.
Scientists are using biotechnology as well as traditional breeding methods to develop water-saving crops to feed a growing world.
Thomas “Tommy” Carter is a plant scientist in North Carolina. He works for the Agricultural Research Service in the United States Department of Agriculture. He leads Team Drought, a group of researchers at five universities. They have been using conventional breeding methods to develop and test soybeans that can grow well under dry conditions.
Tommy Carter started working on drought-resistant soybeans in 1981. His research has taken him as far as China, where soybeans have been grown for thousands of years.
Farmers in the United States, however, have grown soybeans for only about a century. Tommy Carter says the soybeans they grow are for the most part genetically similar. More differences could better protect crops against climate changes that can reduce production. Those changes include water shortages which could increase from global warming.
The Agriculture Department has a soybean germplasm(胚质) collection, a collection of genetic material passed from one generation to the next. Members of Team Drought studied more than 2,500 examples from the collection.
They looked at ones from the home of soybeans, Asia. They searched for germplasms that could keep plants from weakening and wilting (凋谢)during hot, dry summers in the United States.
Tommy Carter says they found only five. But these slow-wilting lines, he says, produce four to eight bushels（英斗）more than normal soybeans under drought conditions. The yield depends on location and environment.
Scientists are also working on other plants that either use less water or use it better, or both. For example, companies like Monsanto, DuPont and Syngenta have been developing corn with reduced water needs. Monsanto expects to be ready in a few years to market its first corn seeds genetically engineered to resist drought.
1. According to the passage, scientists try to find out how to _______.
A. grow crops with less water
B. increase crop production
C. feed a growing world
D. save the world’s water resource
2. Why did Tommy Carter come to China?
A. He likes traveling.
B. China has a long history.
C. He’s doing research into soybeans.
D. He works for the Agricultural Research Service.
3. What’s inferred from the passage?
A. Climate changes lead to global warming.
B. Water shortages contribute to global warming.
C. Genetically different soybeans need much water to grow.
D. Genetically different soybeans help to fight against damaging climate changes.
4. What do we know about slow-wilting plants talked about in the passage?
A. They yield big profits.
B. They can grow in almost any climate.
C. They seem to be drought-resistant.
D. They need much water for their growth.
At least 115 Chinese miners have been pulled alive from a flooded coal mine after more than seven days trapped underground.
Rescuers cheered and some shed tears as the latest survivors emerged alive Monday after more than a week trapped in a flooded mine in north China's Shanxi Province. Officials were also relieved as their round-the-clock rescue mission prevented one of the country's worst mining disasters.
The head of the province's Work Safety ministry, Luo Lin, was among thousands of relatives waiting desperately for news at the pit entrance after rescuers said they had heard voices deep within the mine shaft over the weekend.
It is a miracle in China's mining rescue history, Luo says. He thanked the rescuers for their effort as he counted the miners leaving the entrance.
By late evening Monday, 115 miners had been pulled out alive, China's state media said. They were led to waiting ambulances with their eyes covered to prevent the glare from lights. All are said to be in a stable condition after being trapped in water for nearly nine days. They were able to breathe during their ordeal thanks to air pockets.
Three-thousand rescuers dug and pumped water for seven days to reach the miners at the Wangjialing Coal Mine, which is considered a modern facility.
The first survivors were brought to the surface shortly after midnight on Monday. Attempts to reach the 38 who remain trapped are continuing.
153 people were believed to be trapped underground. But families say this is an underestimate, claiming many more were working in the mine at the time of the flooding.
A preliminary investigation last week found that officials had ignored reports of water leaks prior to the accident.
China relies heavily on coal to fuel its booming economy. But it has some of the most dangerous mines in the world, with many mine bosses ignoring safety concerns to meet demand and chase profits.
The government has sought to improve safety in recent years by clamping down on illegal mines and this seems to have prevented many deaths.
According to official figures, 2,631 coal miners died in 1,616 mine accidents in China in 2009 – down 18 percent from the previous year.
1. Which is the best title of the passage?
A. The Flooded Coal Mine
B. Miners Trapped were Saved
C. The Worst Coal Mine Accident
D. 115 Miners Rescued, 38 Still Missing
2. The underlined word “round-the-clock” in Para 2 most probably means “_______”.
A. finishing before a particular time
B. changing the time shown by clock
C. all day and all night without stopping
D. from the beginning to the end
3. Which of the following is True according to the passage?
A. Coal plays a decisive role in China’s economy.
B. Mine accidents have been increasing in recent years.
C. 115 miners were working underground when the flooding happened.
D. About 3200 coal miners died in mine accidents in China in 2008.
4. At least 115 coal miners were rescued _______.
A. on the day the accident happened
B. after more than 7 days trapped underground
C. after working underground for 9 days
D. 10 days after the accident happened
