1、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. _____. 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 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 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: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。
2、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.Remembering involves getting the material back out when it is ______.【单选题】
A.short - term memory
B.relearning
C.needed
D.coded
E.recognition
F.slow forgetting rate
正确答案:C
答案解析:本题难度不大,答案依据比较明显,在文章第二段:…getting the material back out when it is needed回来看选项,C项needed符合原文句意,是答案。
3、Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world. But ecologists can\'t be everywhere so they\'re turning to non-scientists, sometimes called citizen scientists, forhelp. Climate scientists are not present everywhere. Because there are so many places in the world and not enough scientists to observe all of them, they\'re asking foryour help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. and send their observations to a giant database to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready forthe conditions where they live. All that\'s needed to become one is a few minutes each day oreach week to gather data and send it in. Agroupof scientists and educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group\'s first efforts relies on scientists and non-scientists alike to collect data about plant flowering and leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website. "People don\'t have to be plant experts, they just have to look around and see what\'s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we\'ll be able to make an estimate of how plants and communities of plants and animals will respond as the climate changes. "In "All that\'s needed to become one. . . (paragraph 2)", what does the word "one" stands for?【单选题】
A.a citizen journalist
B.a citizen scientist
C.a scientist
D.a citizen
正确答案:B
答案解析:根据后文a few minutes each day oreach week to gather data…,可见就是对citizen scientist的描述。
4、Walking to Exercise the BrainDo you think sitting and studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn\'t exercise.Previous research had shown that mice learn, remember and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don\'t. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true forpeople. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible forpaying attention and making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching and toning (韵律操) exercises forthe same amount of time.So, even going fora walk every 2 or3 days forjust 10 to 45 minutes can help. That should be good news forthe elderly.The effects of exercising on the brains of younger people haven\'t been studied yet. Still, it can\'t hurt to take occasional breaks and go fora walk orrun around with friends. Whatever you do, though, don\'t try to read and walk at the same time. You could end up hurting yourself!After taking exercise fora few weeks, the mice were found to have ______.【单选题】
A.higher blood pressure
B.faster heartbeat
C.more blood flow to the brain
D.better appearance
正确答案:C
答案解析:本题难度不大,找到答案依据不难。答案依据在文章第三段。带着题干信息词回到文章定位。第三段第二句谈到运动老鼠大脑中的血液流量大于不运动的,回来看选项,很明显,C是近义解释,是答案。
5、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 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 ______ 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】
A.which
B.that
C.something
D.anything
正确答案:D
答案解析:根据语法结构和句意判断D(任何事情)合适。
