Insurance (保险) may be considered a game of risk in which individuals and businesses protect themselves, their families, and their property from possible losses resulting from unpredictable events such as storms, fires, accidents and illnesses. The first rule of the game, devised centuries age, is "share the risk". To play by this rule, many people take a small loss in place of one person′ s taking a large one.
It is a simple idea: an individual pays a small amount of money called a premium (保险费) to an agent who acts on behalf of an insurance company, or underwriter, which holds the individual′s premium and the premiums paid by thousands of others. The individual receives an insurance policy, a promise that if there is a loss to the individual as defined in the policy the insurance company will pay for it. The funds will come from the individual′s premium, the premium paid by others who did not have losses, and money from the company′ s investment of all the premiums. An individual who does not have a loss loses the premium money but purchases what insurance underwriters call "peace of mind". It is a gamble for the customer and the underwriter, but it is built on the first rule of risk that losses are small when shared by many.
Which of the following statements is NOT TRUE?

A.The first rule of the game in insurance business was devised hundreds of years ago.
B.There are many agents who sell insurance policies and collect premiums on behalf of underwriters.
C.An individual who pays premium for a policy is insured by an insurance company.
D.An individual pays premium directly to an insurance company.

When researchers first discovered a link in the late 1990s between childhood adversity and chronic health problem later in life, the real revelation was how common those experiences were across all socioeconomic groups. But the first major study to focus on adverse childhood experiences (ACEs) was limited to a single healthcare system in San Diego. A study published in JAMA Pediatrics- the largest nationally representative study to date on ACEs一confirms that these experiences are universal, yet highlights some disparities among socioeconomic groups.
The current study finds three out of five adults across the U.S. had at least one adverse experience in their childhood, such as divorce, a parent's death, physical or emotional abuse, or a family member's incarceration or substance abuse problem. A quarter of adults have at least three such experiences in childhood, which according to other research- increase their risk for most common chronic diseases, from heart disease and cancer to depression and substance abuse.
"This is the first study of this kind that alows us to talk about adverse childhood experience as a public health problem in the same way we talk about obesity or hypertension or any other highly prevalent population risk factor" says Adam Schickedanz, an assistant professor of pediatrics at the David Geffen School of Medicine at UCLA, who was not involved in the research. "Up until now,we haven't really had a study that takes a national look .
The study researchers, led by Centers for Disease Control and Prevention researcher Melissa T. Merrick, analyzed data from 214, 157 adults in 23 states recently. The participants answered 11 questions about whether they'd experienced what have now become well recognized as ACEs: parental separation or divorce, child abuse (physical, emotional and sexual ), domestic violence and living with someone who has been incarcerated or has a mental ilness or a substance use disorder.Nearly 62 percent of respondents had at least one ACE and a quarter reported three or more. The remaining respondents had at least two ACES, including 16 percent with four or more such experiences .Those identifying as black or Latino and those with less than a high school education or an annual income below $15,000 were more likely to have more ACES. Women, younger adults,unemployed people and those unable to work also tended to have more ACES. But Schickedant cautions that, while the disparities are real, it's important to recognize how common these experiences are among all people, including white and middle class families.”This study shows that ACEs affect people from all walks of life everywhere," he says.
This new study suggests that a need to target prevention resources where they can help most,says Jack Shonkoff, a professor of child health and development at the Harvard T. H. Chan School of Public Health. This requires identifying what makes some people more susceptible than others to the effects of adversity,“Nobody is immune to adverse experiences in childhood but for some population groups, they're a larger burden of childhood adversity than others." he says.
What is found by the first major study on adverse childhood experience(ACEs)?

A. ACEs are common across all socioeconomic groups.
B. There are some disparities for some population groups.
C. ACEs are not directly related to chronic health problems.
D. Children are more vulnerable to adverse experiences than adults.

Only those who worked here for more than five years are eligibie for the special payment.

资料：Placing the right type of workers in close proximity to each other can generate up to a 15 percent increase in organizational performance，according to the study from Cornerstone On Demand，a provider of cloud-based learning and talent-management software，and researchers at Harvard Business School in Massachusetts. For businesses with 2，000 employees, this translates into an additional $1 million in profit each year，the study said.
For the study，researchers examined data from a two-year period of more than 2，000 employees working at a large technology company with locations in the U.S. and Europe. The study’s authors separated workers into three different categories based on the work they produced：
Productive： These employees are very productive，but don’t always produce quality work.
Quality：These workers produce work of superior quality，but aren’t always productive.
Generalists： These employees are average in terms of both productivity and quality.
The researchers defined productivity by how long it takes an employee to finish a task，and effectiveness by how often employees need to ask a co-worker for help completing a task.

What is NOT true about the categories of the workers？

A.There is no particular order of these categories
B.Generalists are those who are neither productive nor effective
C.The frequency employees need to ask a co-worker for help completing a task is recorded as effectiveness
D.Productive workers are those who finish a task quickly

Sleeping

People 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 for
health 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."

The findings indicate that it is all right to sleep for 6.5 hours a night.

Young Adults Who Exercise Get Higher IQ Scores
Young adults who are fit have a higher IQ and are more likely to go on to university,reveals a major new study carried out at the Sahlgrenska Academy and Sahlgrenska University Hospital.
The results were recently published in the Proceedings of the National Academy of Sciences (PNAS)The study involved 1 .2 million Swedish men doing military service who were born be-tween 1950 and 1976 .The research group analyzed the results of both physical and IQ tests the youngsters took right after they started serving the army.
The study shows a clear link between good physical fitness and better results for the IQ test. The strongest links are for logical thinking and verbal comprehension.But it is only fitness that plays a role in the results for the IQ test,and not strength.“Being fit means that you also have good heart and lung capacity and that your brain gets plenty of oxygen,”says Michael Nilsson, professor at the Sahlgrenska Academy and chief physician at the Sahlgrenska University Hospital. “This may be one of the reasons why we can see a clear link with fitness,but not with muscular strength .We are also seeing that there are growth factors that are important.”
By analyzing data for twins,the researchers have been able to determine that it is primarily environmental factors and not genes that explain the link between fitness and higher IQ.
“We have also shown that those youngsters who improve their physical fitness between the ages of 15 and 18 increase their cognitive performance,”says Maria Aberg,researcher at the Sahl-grenska Academy and physician at Aby health centre.“This being the case,physical education is a subject that has an important place in schools,and is an absolute must if we want to do well in maths and other theoretical subjects.”
The researchers have also compared the results from fitness tests during national service with the socio-economic status of the men later in life.Those who were fit at 18 were more likely to go into higher education,and many secured more qualified jobs.

Which of the following is an implication of physical fitness?
A: Brain size.
B: Good logical capacity.
C: Clear logical thinking.
D: Muscular strength.
