A year ago August, Dave Fuss lost his job driving a truck for a small company in west Michigan. His wife, Gerrie, was still working in the local school cafeteria, but work for Dave was scarce, and the price of everything was rising. The Fusses were at risk of joining the millions of Americans who have lost their homes in recent years. Then Dave and Gerrie received a timely gift——＄7，000，a legacy (遗产) from their neighbors Ish and Arlene Hatch, who died in an accident . “It really made a difference when we were going under financially.” says Dave.But the Fusses weren’t the only folks in Alto and the neighboring town of Lowell to receive unexpected legacy from the Hatches. Dozens of other families were touched by the Hatches’ generosity. In some cases, it was a few thousand dollars; in other, it was more than ＄100,000.It surprised nearly everyone that the Hatches had so much money , more than ＄3 million—they were am elderly couple who lived in an old house on what was left of the family farm .Children of the Great Depression, Ish and Arlene were known for their habit of saving. They thrived own (喜欢) comparison shopping and would routinely go from store to store, checking prices before making a new purchase .Through the years, the Hatches paid for local children to attend summer camp when their parents couldn’t afford it. “Ish and Arlene never asked if you needed anything,” says their friend Sand Van Weelden, “They could see things they could do to make you happier, and they would do them.Even more extraordinary was that the Hatches had their farmland distributed. It was the Hatches’ wish that their legacy——a legacy of kindness as much as one of dollars and cent ——should enrich the whole community (社区) and last for generations to come.Neighbors helping neighbors ——that was Ish and Arlene Hatch’s story .56. According to the text, the FussesA. were employed by a truck company B. were in financial difficulty

DCities alarmed by deaths and injuries of pedestrians are taking efforts to make crosswalks safer for people on foot, especially seniors and children who need more time to cross streets.A pedestrian is killed in a traffic accident in the USA every 110 minutes；one is injured every nine minutes, according to official date. Crosswalk can be especially dangerous for the elderly. Among people 70 and older, 36% of pedestrian deaths in 2006 occurred in crosswalks, compared with 21% of those younger than 70 , according to the Insurance Institute for Highway Safety.The Federal Highway Administration（FHWA）advises that next year states increase by nearly 15% the amount of time traffic lights provide for pedestrians to cross the street after the flashing orange hand appears .FHWA spokesman Doug Hecox says reasons for the change include an aging population that needs more time to cross, health-conscious Americans walking more, children encouraged to walk to prevent getting overweight and high gas prices pushing people to walk instead of drive.Pedestrian deaths went down by 12% from 5,449 in 1996 to 4,784 in 2006. But among those in 2006, 471 were killed in crosswalks, down slightly from 488 ten years earlier, the National Highway Traffic Safety Administration (NHTSA) says.53. Which of the following is true according to the text?A. Among 100 pedestrian deaths there were 21 people younger than 70.B. Old people are more likely to meet with accidents in crosswalks.C. Traffic accidents killed more old people than young people.D. About seven traffic accidents happened per hour.

第三篇Exercise Lowers Employers' Health CostsCompanies can save millions in health-care costs simply by encouraging their employees to exercise a little bit,researchers reported on Friday.They said obese（肥胖的）employees had higher health-care costs , but lowered those expenses by exercising just a couple of times a week-without even losing any weight.Feifei Wang and colleagues at the University of Michigan studied 23,500 workers at General Motors.They estimated that getting the most sedentary（惯于久坐的）obese workers to exercise would have saved about$790,000 a year,or about 1.5 percent of health-care costs for the whole group.Company-wide,the potential savings could reach$7.l million per year,they reported in the Journal of Occupational and Environmental Medicine.Of the whole group of workers,about 30 percent were of normal weight,45 percent were overweight（超重的）,and 25 percent were obese. Annual health-care costs averaged $2, 200 for normal weight,$2, 400 for the overweight,and$2, 700 for obese employees.But among workers who did no exercise,health-care costs went up by at least$100 a year,and were$3,000 a year for obese employees who were sedentary.But adding two or more days of light exercise一at least 20 minutes of exercise or work hard enough to increase heart rate and breathing一lowered costs by on average$500 per employee a year,the researchers found."This indicates that physical activity behavior could reduce at least some of the harmful effects of excess body fat,and in consequence,help lower the health-care costs,"Wang and colleagues wrote. By encouraging its employees to exercise General Motors could saveA:$790,000 per year. B:$7.1 million per year.C:$3,000 per year. D:$7,300 per year.

资料：Up to 80 per cent of the world’s middle classes will live in developing countries by 2030 thanks to surprising recent gains in poverty reduction, according to a United Nations report published on Thursday.
“Never in history have the living conditions and prospects of so many people changed so dramatically and so fast.” concludes the UN’s latest Development Report. “The world is witnessing an epochal ‘global rebalancing’.”
Underpinning the improvements in the human development index（HDI） was rapid growth in countries such as China, India and Brazil, with China and India having doubled per capita economic output in less than 20 years. But the study stressed that growth and improvements in HDI spread far beyond the four Bric countries of Brazil, Russia, India and China, and included at least 40 countries that had accompanied greater economic dynamism with effective poverty-reduction policies.
Afghanistan, Sierra Leone, Ethiopia, Rwanda and Angola were among 14 countries that have recorded gains in HDI of more than 2 per cent a year since 2000. Partly as a result, the report found that worldwide extreme income poverty has plunged from 43 per cent in 1990 to just 22 per cent in 2008, including more than 500m being lifted out of poverty in China alone. The report stated that such gains had already helped the world achieve the main poverty eradication goal of the so-called Millennium Development Goals, which called for the share of people living on less than $1.25 a day to be cut by half from 1990 to 2015.
Underpinning this poverty reduction was developing countries’ increasing share of global trade, which grew from 25 per cent to 47 per cent between 1980 and 2010. “The south as a whole is driving global economic growth and societal change for the first time in centuries,” says the report.
The report found that trade among developing countries was the biggest factor in that expansion, increasing from less than 10 per cent of total global trade to more than 30 per cent. “Trade between countries in the south will overtake that between developed nations,” the report said.
“More than 500m being lifted out of poverty in China alone” illustrates ______.A.the economic development of China is important
B.the role of some developing countries is significant for poverty reduction
C.14 countries are developing faster than China
D.it is crucial to make a clear goal first

Older Volcanic EruptionsVolcanoes were more destructive in ancient history,not because they were bigger,but because the carbon dioxide they released wiped out life with greater ease.Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions.Not all volcanic eruptions killed off large numbers of animals,but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock.To his surprise,the older the massive volcanic eruptions were,the more damage they seemed to do.He calculated the"killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava（熔岩）that they produced.He found that size for size,older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.The Permian（二叠纪）extinction,for example,which happened 250 million years ago,is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe.Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide.The global warming that followed wiped out 80 percent of all marine genera（种类）at the time,and it took 5 million years for the planet to recover.Yet 60 million years ago,there was another huge amount of volcanic activity and global warming but no mass extinction.Some animals did disappear but things returned to normal within ten thousand of years."The most recent ones hardlyhave an effect at all,"Wignall says.He ignored the extinction which wiped out the dinosaurs 65 million years ago,because many scientists believe it was primarily caused by the impact of an asteroid（小行星）.He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2．Vincent Courtill.ot,director of the Paris Geophysical Institute in France,says that Wignall's idea is provocative.But he says it is incredibly hard to do these sorts of calculations.He points out that the killing power of volcanic eruptions depends on how long they lasted.And it is impossible to tell whether the huge blasts lasted for tliousands or millions of years.He also adds that it is difficult to estimate how much lava prehistoric volcanoes produced,and that lava volume may not necessarily correspond to carbon dioxide emissions。Why did older volcanic eruptions do more damage than more recent ones?A:Because they killed off life more easily.B:Because they were brighter.C:Because they were larger.D:Because they were hotter.

SleepingPeople who sleep for more than eight hours a night do not live as long as those who sleep for six hours,according to the biggest study yet into sleep patterns and mortality（死亡率）.Scientists have no explanation for the findings and do not know if they mean people who like a lie-in（睡懒觉）can extend their lives by sleeping less.Although it is a common belief that sleeping for at least eight hours a night is vital forhealth and well-being,the six-year study involving more than 1.1 million Americans older than 30 found that those who slept for less than eight hours were far from doing themselves any long-term harm."Individuals who now average 6.5 hours of sleep a night can be reassured that this is a safe amount of sleep.From a health standpoint,there is no reason to sleep longer,"said Daniel Kripke , a professor of psychiatry（精神病学）at the University of California, San Diego.Dr. Kripke said,"We don't know if long sleep periods lead to death.Additional studies are needed to determine if setting your alarm clock earlier will actually improve your health."The scientists,who were funded by the American Cancer Society,found that the best survival rates were among the men and women who slept for seven hours a night.Those who slept for eight hours were 12 per cent more likely to die during the six-year period of the study,when other factors such as diet and smoking were taken into account.Even those who spent a mere five hours a night in bed lived longer than those who slept eight or more hours.However,an increasing death rate was found among those who slept for less than five hours.Dr. Kripke said,"Previous sleep studies have indicated that both short-and long-duration （持续时间）sleep had higher mortality rates. However, none of those studies were large enough to distinguish the difference between seven and eight hours a night,until now." More than one million Americans participated in the six-year study.A:Right B:Wrong C:Not mentioned

单选题The economy of the United states after 1952 was the econnomy of a well-fed,almost fully employed people. Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom. A n economic survey of the year 1955, a typical year of the 1950’s, may be typical as illustrating the rapid economic growth of the decade. The national output was value at 10 percent above that of 1954 (1955 output was estimated at 392 billion dollars). The production of manufacturers was about 40 percent more than it had averaged in the years immediately following World War 2. The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority . Those few seemed to fear that the boom could not last and would eventually lead to the oppsite-depression.
Which of the following were LEAST satisfied with the national economy in the 1950’s?（）A
EconomistsB
FrmaersC
PoliticiansD
Steelworkers
