Exercise Lowers Employers' Health Costs
Companies 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.How can employees help lower the health-care costs?
A:By taking more rest.
B:By eating less.
C:By exercising a little bit.
D:By saving more money.答案：C解析： -

单选题Which of the following is true about the Internet according to the passage?AAmericans were more in contact before the advent of the Internet.
BThe Internet is weakening the tie of social networks.
CIf you use the internet, you are more likely to get help from network members.
DInternet users are more likely to receive help from non-users.
正确答案： B解析：
录音中最后一句提到“Internet users are more likely than non-users to receive help from network members.”(网络用户比非网络用户更有可能获得来自网络成员的帮助)，由此可知如果你使用网络，你更有可能得到网络成员的帮助，所以选C。
【录音原文】
As the size of a person’s social network increases, it becomes more difficult for people to contact a large percentage of network members. The percentage of one’s social network contacted declines as network size grows. This pattern holds true for almost all forms of contact analyzed in the Social Ties survey. The one exception is email.
As the size of people’s social network increases, the percentage of one’s social network contacted weekly by email does not decline, but remains about the same at about 20% of their ties. Several qualities of email help explain this finding. Email enables people to maintain more relationships easily because it is convenient as a communication tool and it gives the control in managing communication. The nature of email is such that people could carry on conversations at different times and at their leisure. This makes it possible for a quick note to an associate, whether it is about important news or seeking advice on an important decision. Moreover, it is almost as easy to email a message to many people as it is to email to only one...
Contrary to fears that email would reduce other forms of contact, there is “media multiplexity”: that is, the more contact by email, the more in-person and phone contact. Therefore, Americans are probably more in contact with members of their communities and social networks than before the advent of the Internet. And Internet users are more likely than non-users to receive help from network members. -

单选题A recent study of an insurance company’s underwriters indicated that those who worked in pleasant physical surroundings were 25 percent more productive than their peers in unpleasant physical surroundings. Objective criteria for evaluating job performance included caseload and complexity of cases. This shows that improving workers’ environments increases those workers’ productivity. Which of the following, if true, most seriously weakens the conclusion above?AOn average, less-productive employees spend no fewer hours per day at their workstations than do their more-productive peers.
BUnpleasant surroundings give employees less motivation to work hard than more pleasant surroundings do.
CThe more-productive employees are generally rewarded with pleasant office space.
DMore-productive employees do not work any more hours than their less-productive peers.
EPeer pressure discourages employees in crowded, unpleasant surroundings from making phone calls to their own family members during work time.
正确答案： D解析：
文段由一项研究的结果：在令人舒适的工作环境中的员工比处于不太舒适的工作环境中的同时的效率高25%，得出结论：改善工人的工作环境能提高他们的效率，文中没有提到工作效率高和环境好的因果关系，所以如果工作效率高导致了工作环境的变好，那么该假设会得到削弱，故本题应选C项。
