1、AirbusDespite 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.Airbus carries out Power 8 because ______.【单选题】

A.it cannot make up the deficits caused by the delays in delivering A380

B.it wants to move its production abroad to handle the problem of dollar\'s decline

C.it has not predicted the dollar decline at the beginning

D.it wants to raise money to build new production sector in low-cost countries

正确答案:A

答案解析:细节考查题。题干考查的是空中客车实行能量8计划的原因。答案参见第二段第一句:空中客车已经实施能量8计划了,目的就是要弥补因为A380交付延误造成的损失,故正确答案为A。B项并非直接原因。C项属于无关信息。D项属于结果而非原因。

2、Arctic MeltEarth\'s North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean fell to a record low. Normally, ice builds in Arctic waters around the North Pole each winter and shrinks during the summer. But for many years, the amount of ice left by the end of summer has been declining. Since 1979, each decade has seen an 11. 4 percent drop in end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner. Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. And it\'s a very large 23 percent below the previous record low, which was set just 2 years ago. This continuing trend has scientists concerned. There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer at the University of Washington at Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water. Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5℃ warmer than average and 1.5℃ warmer than the previous record high. With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3. 3 meters thick at the beginning of the summer measured just 50 centimeters by season\'s end. The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research and Engineering Laboratory in Hanover, N. H. Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover. Which of the following is closest in meaning to the word "build" in the first sentence of the second paragraph?【单选题】

A.construct

B.extend

C.create

D.expand

正确答案:D

答案解析:本句意思为“每年冬天北极附近的北冰洋开始结冰”,build为“结冰”的意思,expand有“容积扩张”的意思,所以与build相符;而construct为“修筑、建筑”的意思,所以不能选。

3、BudgetA budget is a spending plan. It can help you spend money wisely. It can do this by cutting out wasteful spending. Of course, preparing a budget takes planning, and following a budget takes will power. Your budget should meet your family\'s needs and income. The first step in creating a budget is to set your goals. What does your family need and wants. You must know this to work out the details of the budget. Keep goals realistic, in terms of income available. Then decide which goals are the most important. The next step is estimating family income. Before you can plan wisely, you need to know how much money you have to spend! Write down all the money you expect to receive (wages, savings, interest, etc.) during the planned budget period. After you have calculated how much money will be available, it is time to estimate expenses. List all of your family expenses. If you are not satisfied with what you got for your money, look carefully at your spending. Studying your records will show where overspending has occurred. It will also point out poor buying habits. It is also a good idea to set aside a small amount of money for emergencies. Every family has small emergencies: a blown tire, a broken device, or the need for minor medical care. The writer suggests that it is a good idea to set aside some money because____. 【单选题】

A.you probably will not be able to follow your budget

B.people usually spend more than they plan to do

C.things can happen unexpectedly

D.others may want to borrow some money from you

正确答案:C

答案解析:从原文最后的“It is also a good idea to set aside a small amount of money for emergencies. Every family has small emergencies”可以知道,每个家庭都会有一些意外情况发生,所以有必要准备一小笔资金作为备用金。

4、The Book of LifeSo far, scientists have named about 1.6 million living species, and that\'s a just a fraction of that probably exists on Earth. With so many plants, animals and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.To get the encyclopedia started, the creators will use information from scientific databases that already exist. And eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, for example, will be able to input which bird they\'ve seen and where. The technology for this kind of tool has only become available.As the EOL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生态系统) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven\'t been reviewed.Another convenient feature of the EOL is that you\'ll be able to pick the level of detail you want to see to match your interest, age and knowledge. If you wanted to learn about bears for a science class report, for example, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature and exploration of bears.It now takes years for scientist to collect all the data they need to describe and analyze species. The creator of the Encyclopedia of Life hope that their new tool will speed up that process.Which of the following statement is NOT true? ______【单选题】

A.The EOL will be beneficial to school kids with its development.

B.Scientists will review every piece of the information added to EOL.

C.Scientists have cataloged only a small part of the living species.

D.People with different interests and knowledge will in a way find EOL useful.

正确答案:B

答案解析:本题有一定难度,需要通读全文,寻找答案依据。答案依据主要在文章第四段倒数第二句:To make sure the encyclopedia is accurate.scientists will review much of the information added to it.显然,科学家是review much of the information,而不是every piece of the information,选项B项和原文句意不符,是答案。

5、Arctic MeltEarth\'s North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But for many years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drop in end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. And it\'s a very large 23 percent below the previous record low, which was set just 2 years ago.

In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.It can be learned from the last sentence that ______.【单选题】

A.the ice melt in the Arctic may never stop

B.scientists are trying hard to stop the ice melt in the Arctic

C.scientists are delighted to find out what is going on in the Arctic

D.the warming trend in the Arctic can be reversed in the near future

正确答案:A

答案解析:本题难度不大,最后一句话的句意不难理解。文章最后一句谈到,科学家们担心北极处于变暖趋势,而且不能挽回,答案是B。
