1、AirbusDespite bulging ｏｒｃｅｒbooks, 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 fｏｒostensibly 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" fｏｒthe 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" ｏｒlow-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 offｓｅｔthe 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% fｏｒthe 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 fｏｒoutsourcing: 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 fｏｒthe 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, fｏｒits part, wants to shift the blame fｏｒdelays 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 sectｏｒin 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、A special educationVideodisc holds great promise of helping to meet the needs of American schoolchildren who have problems seeing, hearing, speaking, ｏｒsocializing. Almost eleven percent of the students aged 3-21 in this country have an impairment that affects their ability to benefit from a regular education program. Handicapped students require special education because they are often markedly different from most children in one ｏｒmore of the following ways: mentally retarded (发展迟缓的) learning-disabled, emotionally disturbed, deaf, visually handicapped, physically handicapped, ｏｒother health impairments. The education of these handicapped children is rewarding but challenging. A special education student usually needs a longer period of time to acquire information. Repetitive teaching techniques are often beneficial, ａｎｄ　indefatigable (孜孜不倦) consistency on the part of the teacher is frequently necessary. Interactive videodisc courseware has characteristics that can be capitalized upon to meet the challenges that special education poses. A videodisc program is infinitely patient. Repetition of any videodisc lesson can continue endlessly, ａｎｄ　designers can assure absolute consistency within a program. Most important, according to special educatｏｒWilliam Healey of the University of Arizona, is that videodisc "adds an extra dimension of realism fｏｒchildren who need graphic representations."Healey explained that deaf ａｎｄ　mentally retarded children especially have difficulty grasping figurative language ａｎｄ　higher-ｏｒｃｅｒlanguage concepts. He believes that fｏｒspecial education, the power of videodisc lies in the ability of the technology to visually represent language concepts normally taken fｏｒgranted by non-handicapped persons. Complex figurative language forms such as idioms ａｎｄ　metaphors come most readily to mind as being difficult fｏｒhandicapped learners. A videodisc courseware is beneficial to those who have study difficulties because______【单选题】

A.its fancy design is very attractive

B.it allows the user to go back to where he wants to restudy

C.the content of it is healthy ａｎｄ　promising

D.it is developed by university professors

正确答案:B

答案解析:文章第2段第2句指出，残疾儿童往往需要老师不厌其烦地反复教导，接着谈到互动式影碟课件可以不断地重放课程，由此推断，影碟课件使学习有困难的学生能够回放他们想再次学习的课程，故选B。

3、Meet Your Memory1. Memory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. 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), ｏｒgrouping 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 fｏｒit. 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 ｏｒｃｅｒit 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.Paragraph 3 ______【单选题】

A.Why do we forget things?

B.How do we measure memory?

C.What are the stages memory consists of?

D.What is the difference between short - term memory ａｎｄ　long - term memory?

E.What is memory?

F.Who may have a poｏｒmemory?

5、Will We Take Vacation in Spaces?When Mike Kelly first ｓｅｔout to build his own private space-ferry service, he figured his bread-and-butter business would be lofting (发射) satellites into high-Earth orbit. Now he thinks he may have figured wrong. "People were always asking me when they could go," says Kelly, who runs Kelly Space & Technology out of San Bemardino, California. "I realized that real market is in space tourism."According to preliminary market surveys, there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington, Virginia, has taken more than 130 deposits fｏｒa two-hour, $98, 000 space tour tentatively ａｎｄ　somewhat dubiously (可疑地) ｓｅｔto actｏｒby 2005. Gene Meyers of the space Islａｎｄ　Group says: "Space is the next exotic(风光奇特的) vacation spot. "This may all sound great, but there are a few hurdles (困难). Putting a simple satellite into orbit with no oxygen, life support ｏｒreturn trip necessary already costs an astronomical (天文数字) $ 22,OOO/kg. ａｎｄ　that doesn\'t include the oust of insuring rich ａｎｄ　possibly litigious passenger. John Pike of the Federation of American Scientists acerbically (尖刻地) suggests that the entireｇｒｏｕｐof entrepreneurs trying to corner (垄断) the space-tourism market have between them "just enough money to blow up one rocket."The U. S. space agency has plenty of money but zero interest in mailing space less expensive fｏｒthe little guys. So the little guys are racing to do what the government has failed to do: design a reusable launch system that is inexpensive, safe ａｎｄ　reliable. Kelly Space\'s prototype looks like a plane that has sprouted rocket engines. Rotary Rocket in Redwood City, California, has a booster with rotors to make a helicopter-style return to Earth; Kistler Aero-space in Kirkland, Washington, is piecing together its versions from old Soviet engines, shuttle-style thermal protection tiles ａｎｄ　an elaborate parachute system. The first passenger countdowns are still years away, but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations. After all, you can\'t be too prepared, fｏｒa trip to that galaxy far, far away. Fｏｒthose who are intent on joining the 100-mile high club, Hilton ａｎｄ　Budget are plotting to build space hotels. Before the Russian spaceship Mir came down, some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space, ａｎｄ　if you are thinking of staying in it, you may want to check the Michelin ratings before booking yourself a suite. It sounds great that soon there will be space residence, although it is still a tentative plan. 【单选题】
