1、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack ｏｒstroke later in life ａｎｄ　could prevent hundreds of ______ of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections ａｎｄ　allergies ａｎｄ　are less prone to obesity. British scientists have now shown that breastfeeding ａｎｄ　slow growth in the first weeks ａｎｄ　months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol ａｎｄ　increasing their tendency to diabetes ａｎｄ　obesity-the four main risk factors fｏｒstroke ａｎｄ　heart attack." said ProfessｏｒAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure ａｎｄ　cholesterol later in life are greater than anything adults can do to control the risk factors fｏｒcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack ａｎｄ　strokes, each year, according to the World Health Organization. Lucas ａｎｄ　his colleagues compared the health of 216 teenagers who as babies had either been breastfed ｏｒgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol ａｎｄ　lower concentrations of a protein that is a marker fｏｒcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks ａｎｄ　months of life, the greater was their later risk of heart disease ａｎｄ　stroke. The effect was the same fｏｒboth boys ａｎｄ　girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【单选题】

2、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.According to the passage, the 787 programme is delayed probably because ______.【单选题】

A.the partners are not incapable of building the plane

B.The suppliers are far away from the main assembly operation

C.80% of it has been outsourced to other countries which affected efficiency

D.the executive is not qualified incapable of finding qualified partners

正确答案:B

答案解析:推理题。题干考查的是787项目被延误的原因。答案参见第四段：可能的原因有两方面，不能胜任的合作人和运输飞机半成品部件的费用，故正确答案为B。

3、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 ｏｒwhat 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, fｏｒexample, will be able to input which bird they\'ve seen ａｎｄ　where. The technology fｏｒthis kind of tool has only become available.As the EOL develops, you might find it useful fｏｒschool projects. The site will feature special pages fｏｒkids 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 fｏｒa science class report, fｏｒexample, 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 fｏｒscientist to collect all the data they need to describe ａｎｄ　analyze species. The creatｏｒof the Encyclopedia of Life hope that their new tool will speed up that process.At the starting stage, the EOL will get information from ______. 【单选题】

A.all the Web sites available

B.ｄａｔａｂａｓｅs built up by its creators

C.Nonscientist with specialized knowledge

D.the existing scientific ｄａｔａｂａｓｅs

正确答案:D

答案解析:本题难度不大，答案依据比较明显。带着题干信息词回文章定位，答案依据主要在文章第三段第一句：To get the encyclopedia started，the creators will use information from scientific ｄａｔａｂａｓｅs that already exist.谈到了主要从现有的科学数据库获取信息，回来看选项，D项和原文句意相近，是答案。

5、AIDSAs a science writer, I don\'t have to wear emotional armｏｒvery often. Before I went to Zimbabwe fｏｒa visit, I had talked to other reporters who had spent time in Africa. All told me to get prepared fｏｒthe orphans, many of whom had caught the AIDS virus from their mothers ａｎｄ　the strong desire to make everything all right fｏｒthem. Then again, nothing could have prepared me fｏｒthe visit to creche(育婴堂) fｏｒAIDS orphans in Harare, where one sick, smiling four-year-old boy tried to keep up with the other kids playing ring-around-the-rosy but was so weak he kept falling to the floor, ｏｒmeeting a 25-year-old unmarried girl who cared fｏｒher nephew Only when I got back about a week later The boy who called his aunt "Mama" was too weak even to take the piece of banana I offered. Meanwhile photojournalist Karin Retief was visiting a room at the hospice (济贫院) where she had been told a particularly sweet orphan boy stayed. At first she did not see anyone on the bed ａｎｄ　was about to say he must be elsewhere, when suddenly she spotted his tiny arm in the air, his body lost in the folds of the bedclothes. Recently Karin wrote to me that she had been able to keep our assignment from taking too great an emotional suffering at the time. " ______, could I moum the people I met", she continued. "I sat in church ａｎｄ　wanted to ask the priest to pray fｏｒthe people with AIDS in Zimbabwe ａｎｄ　all over the world. Then all the people\'s faces, pain ａｎｄ　suffering became so real, I could not get the words out. I broke down ａｎｄ　cried ａｎｄ　cried fｏｒthem". 【单选题】
