2、ld take about eight months on a modern spaceship. That might seem like a great opportunity to catch up on your sleep. 1 “If we at some point really want to go to Mars and we want to send humans, then we need to know how they will cope,“ Mathias Basner told Science News. He is a sleep researcher at t

3、he University of Pennsylvanias Perelman School of Medicine in Philadelphia. 2 Their experiment was like a long-running game of make-believe: Six men spent 520 days a little more than 74 weeks on a pretend voyage to Mars. In fact, the crew spent the entire time confined inside a small, windowless cap

4、sule in Moscow, Russia. 3 During their “trip,“ the travelers pretended to land on Mars and to carry out science tests. Throughout the pretend trip, other scientists collected data on the travelers. 4Once every minute, that device recorded the mans motions. From these data, Basners team found that th

5、e volunteers were less active and slept more as the pretend mission continued. During the last 18.5 weeks of the trial, most participants were sleeping more each day than they had during the first 18.5 weeks. 5One mans natural sleep cycle shifted from a roughly 24-hour day to almost 25 hours long.(B

6、y coincidence, that time is closer to the length of a day on Mars.)This meant that he was sometimes awake when his crew members were asleep, and vice versa. 6Tests showed that he became less alert. Messing with sleep can have serious consequences, says Jeffrey Sutton. 7He also directs the Center for

7、 Space Medicine at the Baylor College of Medicine in Houston. “When you are doing high-risk behavior in space, a performance deficit can be life threatening, he told Science News. The decrease in activity found by Basners team could also prove problematic in space, says Sutton. 8 A. Hes a doctor and

8、 scientist who worked on the study. B. Another one of the six pretend travelers slept less over time. C. His team published its new findings in early January. D. Each participant wore a device on his wrist. E. Astronauts may need to increase their exercise to stay healthy. F. But a recent experiment

9、 finds that people may develop sleep problems on a long space journey or at least on the pretend trip in these tests. G Four of the men also developed sleep problems. H. The goal of this trial: to learn how people would cope with living in close quarters during travel to and from the Red Planet.（分数：

On its 75th anniversary Social Security is once again under attack and so are its defenders. Those who

11、would axe benefits are spreading myths designed to make you think there is a looming crisis. Well, it is just not true. The stark reality is that it will be several decades before the program encounters any financial problems. The programs trust fund will have a $4.3 trillion surplus by 2023, and ca

12、n pay all its obligations for decades to come. And strengthening Social Security is easymaking the very rich pay their fair share by lifting the cap on contributions by the wealthy would allow the program to pay all its obligations indefinitely. 2. Social Security was a centerpiece of FDR(Franklin D

13、elano Roosevelt)s New Deal reforms that helped this country recover from the Great Depression. These programs provided Americans a measure of dignity and hope and lasting security against the vicissitudes of the market and life. FDR therefore accomplished what the venerable New Deal historian David

14、Kennedy says is the challenge now facing President Obama a rescue from the current economic crisis which will also make us “more resilient to face those future crises that inevitably await us.“ 3. This anniversary is also a reminder of how major social reforms in this country have come aboutin fits

15、and starts. As former Clinton adviser Paul Begala observed in a Washington Post op-ed, “No self-respecting liberal today would support Franklin Roosevelts original Social Security Act. If that version of Social Security were introduced today, progressives like me would call it cramped, parsimonious,

16、 mean-spirited and even racist. Perhaps it was all those things. But it was also a start. And for 74 years we have built on that start.“ 4. Indeed when Social Security was first passed it left out African Americans and migrant workers. It was an imperfect piece of legislation but one that progressiv

17、es built on to create the program we know todaya program like Medicarethat people feel an emotional connection to and will fight to protect. A new campaign from MoveOn and Campaign for Americas Future will tap into that energy, enlisting candidates to pledge their support to Social Security this ele

18、ction seasonopposing any cuts in benefits, including raising the retirement age. And these candidates would be wise to pay attention: A just-released poll shows that 65% of voters reject raising the retirement age to 70. And a separate AARP(American Association of Retired Persons)poll shows the vast

19、 majority oppose cutting Social Security to reduce the deficit, and 50% of non-retired adults are willing to pay more now in payroll taxes to ensure Social Security will be there when they retire. 5. Progressives can also mark this anniversary by not only rededicating themselves to defending Social

20、Security, but also going on the offensive to expand and improve our social security system to provide economic security for everyone.

26、your Answer Sheet Small, Imperfectly Formed One has to look a long time for an American politician of any political stripe who has failed to laud small businesses. Still, many have little clue as to what makes such businesses succeed or fail. Federal agencies aimed at helping small business, such as

27、 the Small Business Administration and the Minority Business Development Agency, have been around for half a century, yet persistent differences remain between the performance of businesses founded by white, male entrepreneurs and the rest. Blacks are less likely to be self-employed, for example, an

28、d when they are their businesses, on average, have lower sales and profits than do their white-or Asian-owned counterparts. If researchers could explain the causes of these differences, policy-makers could(at least in theory)supply small businesses with more useful help. Two researchers for the Cens

29、us Bureaus Centre for Economic Studies, Ron Jarmin and C.J. Krizan, recently published a working paper attempting to understand demographic differences behind small businesses success and failure. They concentrated on the years 2002 to 2005, with three databases at their disposal: the Survey of Busi

30、ness Owners, conducted every five years; the Longitudinal Foreign Trade Transaction Database, which includes every US export transaction between 1992 and 2005; and a database co-developed by Mr. Jarmin, which allowed the authors to track whether the owners of the firms in their sample had prior expe

31、rience being their own bosses. By drawing from on the power of the Censuss data collection efforts, the authors hoped to create a more nuanced picture of business survival. Some of their findings were not terribly surprising. A firms chances of survival, regardless of the race or sex of its owner, d

32、ecreased in poorer areas; and the better the education of the founder, the more likely it was to succeed. Businesses owned by Asians, Hispanics, or Pacific Islanders were more likely to be exporters. Older entrepreneurs were more likely to use personal savings to start their businesses; younger owne

33、rs were more likely to have to close up shop during the study period than were their middle-aged rivals. However, the data also confirmed that black and female owned businesses tended to perform worse than the average. They were also less likely to have been funded by bank loans. Still, the business

34、es that survived, regardless of the owners race, tended to add employees at similar rates. Furthermore, after controlling for factors such as the education and race of the owner, there was no statistically significant difference in firms abilities to expand into different locations. Finally, black e

35、ntrepreneurs were more likely to have a history of self-employment than their white counterparts. Messrs Jarmin and Krizans paper is not the first to suggest that black entrepreneurs, less likely to have other business owners in their family or personal networks, tend to “start small“ when they vent

36、ure out on their own. Most researchers get to end their papers by speculating, usually without much fear of consequence, as to the policy implications of their work. The authors of this paper, not wishing to imply that the Census Bureau might have policy opinions, declined to do so. But the reader c

37、an make some guesses. One is that mentorship programmes may be particularly useful for promoting entrepreneurship among blacks. Another is that reaching out to businesses based on the owners race might be less useful than supporting businesses in poorer areas. And small businesses of all stripes wou

38、ld be helped by improving that other institution lauded by politicians: Americas education system.（分数：14.00）(1).Most politicians in the U.S. _.（分数：2.00）A.have had some experiences in running a small businessB.have made great efforts in helping small businessesC.have paid little attention to small bu
