1、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack ｏｒstroke later in life ａｎｄ　could prevent hundreds of thousands 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 ______ 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、A Bad IdeaThink 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. ａｎｄ　you\'ll be fined $ 100 if you do so on a New York city street. 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. Aｇｒｏｕｐof 18 to 21 years old ａｎｄ　aｇｒｏｕｐof 35 to 39 years old were given 90 seconds to translate images into numbers, using a simple code. The youngerｇｒｏｕｐdid 10 percent better when not interrupted. But when both groups were interrupted by a phone call ｏｒan instant message, the olderｇｒｏｕｐmatched the youngerｇｒｏｕｐin 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 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 youngerｇｒｏｕｐdid 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:B

答案解析:本题有一定的难度，需要认真阅读文章，理解好句意。可用排除法和代入法。本题的下文谈到了对（办公室）职工做的一次调查，涉及具体内容，所以可以推断此处应该是概括性的句子，来引导下文，而且和职工调查有关，回来看选项，把B代入文中，符合逻辑，答案是B。

3、Houses of the FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict. What will our home be like then?Future houses will have to be flexible. In thirty years\' time even more of us will be working from home. So we will have to be able to use areas of the house fｏｒwork fｏｒpart of the day ａｎｄ　fｏｒliving fｏｒthe rest. Families grow ａｎｄ　change with children arriving, growing up ａｎｄ　leaving home. _____. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines ａｎｄ　discuss with them what to do. Like this, "We\'ll be having a party this weekend. What food shall we cook?" ａｎｄ　the machine will tell us what food we will have to buy ａｎｄ　how to cook it. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.The house of the future will be personal, each house will be different. You will be able to change the colｏｒof the wall easily.You won\'t have to paint them-you\'ll be able to tell the wall to change the color! ａｎｄ　if you don\'t like the colｏｒthe next day, you will be able to have a new one. The only thing you won\'t be able to do is move the house somewhere else!【单选题】

4、Arctic MeltEarth\'s North ａｎｄ　South Poles are famous fｏｒbeing 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 fｏｒmany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent ｄｒｅｐin 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 ｓｅｔjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons fｏｒthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in 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 3.57 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.The Beaufort Sea mentioned in paragraph 7 is an example to show ______.【单选题】

A.how accurate the new measurements are

B.how thick the ice is in it

C.how serious the problem of the ice melt in the Arctic is

D.how dangerous it is to travel to it

正确答案:C

答案解析:本题难度不大，答案依据比较明显，文章第七段和第八段谈到，夏天冰层以超出科学家预料的速度迅速融化，答案是C。

5、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting ______ about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.invention

B.experiment

C.theory

D.paper

正确答案:C

答案解析:本题有一定难度，考查词义辨析，干扰项有一定的干扰。根据上下文逻辑，文章此处是说“……在研究有关光子的一种有意思的理论”，答案是C。
