1、Airbus
Despite bulging order books, the mood at Airbus and Boeing is far from celebratory. Both aviation giants are moaning loudly that their production systems and supply chains are flawed, albeit for ostensibly different reasons. This week Louis Gallois, the boss of EADS, the Franco-German aerospace consortium that owns Airbus, added substance to warnings a week earlier by the planemaker’s chief executive, Tom Enders, that the dollar's decline was "life-threatening" for the firm. Mr. Gallois said it was no longer just a possibility that Airbus would have to move a large part of its production to "the dollar zone" or low-cost countries, but a certainty.
Airbus is already in the middle of Power 8, a big restructuring plan that involves the loss of 10,000 jobs and the sale of several plants, which is meant to offset the losses caused by the delays in delivering the A380 superjumbo. But Power 8 assumed that a euro was worth $ 1.35, not today's $ 1.47. Mr. Gallois estimates that each 10-cent rise in the euro costs Airbus 1 billion. At present, Airbus makes 76% of its purchases within Europe, but generates over 60% of its sales elsewhere. It must now shift some production abroad.
Airbus is now likely to forge ahead much further. Mr. Gallois suggests that when the A350 enters service in 2013, 70% of it will have been "purchased" in dollars, against 50% for the A380 and an average 24% of Airbus production today. Because Airbus insists that some of its European suppliers price in dollars that means about 50% of the A350's production will be outsourced. New aircraft, such as the A320's successor, may be made almost entirely outside the euro-zone.
Airbus maintains that exchange rates are not the only reason for outsourcing: it is keen to tap into composite-manufacturing expertise wherever it exists. It also insists that it will not repeat the mistakes Boeing has made with its new 787 Dreamliner, about 80% of which has been outsourced. A few weeks ago Mike Bair, the executive responsible for the 787 programme, who was recently moved sideways after mounting production delays, launched a withering attack on some of the companies recruited to build the plane. He said that in future Boeing would not entrust design work to partners who "proved incapable of doing it", and would make suppliers build factories close to Boeing's main assembly operation, rather than flying semi-finished sections of the aircraft round the world on huge Dreamlifter transporters.
It is too early to conclude that the two rivals are heading in opposite directions- Boeing renouncing the global supply chain just as Airbus adopts it. Each company has its own axe to grind. Airbus needs greater flexibility, and the weak dollar provides helpful cover as it takes on its grumbling unions. Boeing, for its part, wants to shift the blame for delays to the 787 on to its partners. The logic of global outsourcing in the aerospace industry remains powerful. Whatever they may be saying now. Airbus and Boeing are more likely to converge than to diverge.
The lesson Airbus learns from Boeing's case of 787 Dreamliner is ______.
【单选题】

A.it should not adopt outsourcing at all given its uncertainty and insecurity

B.it should not cooperate with partners in designing

C.it should not waste time in flying the semi-finished sections of the aircraft

D.it should make use of the local manufacturing expertise instead of international partners

正确答案:D

答案解析:细节考查题。题干考查的是从波音787“梦之机”事件中空中客车得到的教训是什么。答案参见第四段：空中客车指出要海外采购的另外一方面原因是如果当地有制造技术那么就直接运用该技术，故正确答案为D。

2、Animal's "Sixth Sense"
A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.
Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island's coast clearly missed wild beasts, with no dead animals found.
"No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy director of Sri Lanka's Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka's biggest wildlife reserve and home to hundreds of wild elephants and several leopards.
"There has been a lot of scientific evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior assistant at Johannesburg Zoo. "There have been no specialist studies because you can't really test it in a lab or field setting," he told Reuters. Other authorities concurred with this assessmetn.
"Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.
Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense" -or some other mythical power-is an enduring one which the evidence on Sri Lanka's ravaged coast is likely to add to. The Romans saw owls ______ omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.

4、Dung to Death
Fields across Europe are contaminated with dangerous levels of the antibiotics given to farm animals. The drugs, which are in manure sprayed onto fields as fertilizers, could be getting into our food and water, helping to create a new generation of antibiotic-resistant "superbugs".
The warning comes from a researcher in Switzerland who looked at levels of the drugs in farm slurry ______
Some 20,000 tons of antibiotics are used in the European Union and the US each year. More than half are given to farm-animals to prevent disease and promote growth. But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.
Most researchers assumed that humans become infected with the resistant strains by eating contaminated meat. But far more of the drugs end. up in manure than in meat products, says Stephen Mueller of the Swiss Federal Institute for Environmental Science and Technology in Dubendorf. And manure contains especiaily high levels of bugs that are resistant to antibiotics he says.
With millions of tons of animals manure spread onto fields of crops such as wheat and barley each year, this pathway seems an equally likely route for spreading resistance, he said. The drugs contaminate the crops, which are then eaten. They could also be leaching into tap water pumped from rocks beneath fertilized fields.
Mueller is particularly concerned about a group of antibiotics called sulphonamides. They do not easily degrade or dissolve in water. His analysis found that Swiss farm manure contains a high percentage of sulphonamides; each hectare of field could be contaminated with up to 1 kilogram of the drugs. This concentration is high enough to trigger the development of resistance among bacteria. But vets are not treating the issue seriously.
There is growing concern at the extent to which drugs, including antibiotics, are polluting the environment. Many drugs given to humans are also excreted unchanged and are not broken down by conventional sewage treatment.
【单选题】

A.They do not easily degrade or dissolve in water.

B.And manure contains especiaily high levels of bugs that are resistant to antibiotics he says.

C.Animal antibiotics is still an area to which insufficient attention has been paid

D.But recent research has found a direct link between the increased use of these farmyard drugs and the appearance of antibiotic-resistant bugs that infect people.

E.His findings are particularly shocking because Switzerland is one of the few countries to have banned antibiotics as growth promoters in animal dead.

F.They could also be leaching into tap water pumped from rocks beneath fertilized fields.

正确答案:E

答案解析:本句中包含he这个代词，故上文中必定有它的先行词，his findings又表明此人应该是从事科研工作的，句中又提到Switzerland，考虑这种种因素，填入E是正确的。

5、People don't realize how serious this recession has actually been. 【单选题】

D.remember

正确答案:A

答案解析:realize：意识到，和know（知道、了解到、熟悉）意思相近；think:认为、觉得；doubt:怀疑、疑惑、疑问；remember:回忆起、纪念。

6、Seeing Red Means Danger Ahead
The color red often means danger and by paying attention, accidents can be prevented. In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports or other kinds of materials could one day contain a color switching material. It will turn red before a structure collapses or falls apart.
The secret behind the color switching material is a particular type of molecule. A molecule is a group of atoms held together by chemical bonds. Molecules come at all shapes and sizes, and make up everything. You can see, touch or feel. How a molecule behaves depends on what kinds of atoms it contains, and how they're held together.
When a polymer (聚合物) containing a color switching molecule called a mechanophore (机械响应性聚合物) which is about to break, it produce a color. When a polymer with mechanophore molecules becomes "injured" or weak, one of the mechanophore bonds breaks and the material turns red. "It's a really simple detection method. "says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color switching polymers in their lab. The test results proved encouraging.
There is a way to get rid of the color light when a bright light is shone on the mechanophore.
The broken bond is fixed and the red color disappears. This "self-healing" may be a problem for engineers. They need to use the color changer in big construction projects that will be outside in sunlight. And sunlight will make the mechanophore's warming system ______. Sottos and her fellow scientists still have a lot of work to do before the color switching molecules can be used outside the lab.
【单选题】

A.dangerous

B.useless

C.helpful

D.important

正确答案:B

答案解析:前后文是转折关系，前面说到是问题，又有warning system的说法，应该是使之失效的意思，选useless。

7、How to Be a Successful Businessperson
Have you ever wondered why some people are successful in business and others are not? Here's a story about one successful businessperson. He started out washing dishes and today he owns 168 restaurants.
Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, and when he was 16 years old, he learned to fly a small plane.
At the age of 23 and with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working for a company that rented cars.
While Mr. Kazi was working at the car rental(租赁的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. For two months, he worked as a cook's assistant. His job was to clean the kitchen and help the cook. "I didn't like it," Mr. Kazi says, "but I always did the best I could."
One day, Mr. Kazi's two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.
A few months later, the owners needed a manager for a new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager and soon the restaurant was making a profit.
A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside and the food was terrible. Mr. Kazi borrowed money from a bank and bought the restaurant. For the first six months, Mr. Kazi worked in the restaurant from 8 a. m. to 10 p. m. , seven days a week. He and his wife cleaned up the restaurant, remodeled the front of the building, and improved the cooking. They also tried hard to please the customers. If someone had to wait more than ten minutes for their food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.
A year later, Mr. Kazi sold his restaurant for a profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, and retrained the employees. Before long these restaurants were making a profit, too.
Today Mr. Kazi owns 168 restaurants, but he isn't planning to stop there. He's looking for more poorly managed restaurants to buy. "I love it when I go to buy a restaurant and find it's a mess," Mr. Kazi says. "The only way it can go is up. "
To save a failing restaurant, Mr. Kazi did all the following things, EXCEPT to ______.【单选题】

A.clean it up

B.improve the food

C.retrain the employees

D.advertize for it

正确答案:D

答案解析:本题有一定难度，仔细通读文章后半部分可以发现文章没有提到做广告的事情，所以不难确定答案D。

8、Meet Your Memory
1. Memory is something that cannot be seen, touched or weighed. It is thought to be abstract. It is a set of skills rather than an object. Neither is there a single standard for judging a good or poor memory. There are a number of different ways in which a person may have a good memory.
2. Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material; (2) storage refers to keeping the material in the brain until it is needed; (3) retrieval (提取) refers to getting the material back out when it is needed:
3. Memory consists of at least two different processes: short - term memory and long - term memory. Short - term memory has a limited capacity and a rapid forgetting rate. Its capacity can be increased by chunking (组成大块), or grouping separate bits of information into larger chunks. Long - term memory has an almost unlimited capacity.
4. One measure of memory is recall, which requires you to produce information by searching the memory for it. In aided recall, you are given cues (提示) to help you produce the information. In free - recall learning you recall the material in any order. In serial learning you recall it in the order it was presented and in paired - associate learning you learn pairs of words so that when the first word is given you can recall the second word. A second measure of memory is recognition, in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time and how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.
Long - term memory has an almost unlimited capacity and a ______.
【单选题】

A.short - term memory

B.relearning

C.needed

D.coded

E.recognition

F.slow forgetting rate

正确答案:F

答案解析:本题有一定难度，需要认真第三段，吃透句意。这一段谈到短期记忆和长期记忆是两个不同的过程，短期记忆遗忘率高，那么换句话说长期记忆遗忘率低，回来看选项，F项slow forgetting rate符合原文句意，是答案。

9、A Bad Idea
Think you can walk, drive, take phone calls, e - mail and listen to music at the same time 7 Well, New York's new law says you can't. _____. The law went into force last month, following research and a shocking number of accidents that involved people using electronic gadgets (小巧机械) when crossing the street.
Who's to blame? Scientists say that our multitasking (多任务处理) abilities are limited. "We are under the impression that our brain can do more than it often can," says Rene Marois, a neuroscientist (神经科学家) in Tennessee. "But a core limitation is the inability to concentrate on two things at once."
The young people are often considered the great multitaskers. However, an Oxford University research suggests this perception is open to question. A group of 18 to 21 years old and a group of 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The younger group did 10 percent better when not interrupted. But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.
It is difficult to measure the productivity lost by multitaskers. Jonathan Spira, chief analyst at Basex, a business - research firm, estimates that the cost of interruptions to the American economy is nearly $ 650 billion a year. The estimate is based on surveys with office workers. The surveys conclude that 28 percent of the workers' time was spent on interruptions and recovery time before they returned to their main tasks.
【单选题】

A.Talking on a cell phone while driving brings you joy anyway.

B.The estimate is based on surveys with office workers.

C.The younger group did 10 percent better when not interrupted.

D.However, an Oxford University research suggests this perception is open to question.

E.Scientists say that our multitasking (多任务处理) abilities are limited.

F.And you'll be fined $ 100 if you do so on a New York city street.

正确答案:F

答案解析:本题难度不是很大。可用排除法和代入法。本题的上文谈到纽约新的法律规定在走路开车时不能打电话，发邮件，听音乐，下文转到谈新法律发生效力时间，所以可以推断此处会继续跟着上文展开阐述，应该讲如果你做了会导致什么结果，回来看选项，把F代入文中，符合逻辑，答案是F。

10、Light Night, Dark Stars
Thousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文学家) with the University Corporation for Atmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they're lucky to see 150 stars.
If you've ever driven toward a big city at night and seen its glow from a great distance, you've witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates (照亮) the night sky. This haze (朦胧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.
Dust and particles of pollution factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."
Hazy skies also make it far more difficult for astronomers to do their jobs.
Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使变模糊) the faint (微弱的) light give off by distant stars. And if scientists can't locate these objects, they can't learn more about them.
Light pollution doesn't only affect star visibility. It can harm wild life too. It's clear that artificial light can attract animals, making them go off course. There's increasing evidence, for example, that migrating (迁徙) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破坏性的) influence." Sometimes birds fly into lighted towers, high - rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.
Light pollution occurs when ______.【单选题】

A.artificial lights illuminate the night sky

B.the moon lights up the night sky

C.too many stars are visible in the night sky

D.streetlights are turned off

正确答案:A

答案解析:本题难度不大，答案依据比较明显，在文章第二段第二句，谈到当来自街灯等人工灯光射入天空时，就会发生光污染，回来看选项，A项符合原文句意，是答案。
