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.

Text 2 Britain's flexible labour market was a boon during the economic slump,helping keep joblessness down and then,when the recovery began,allowing employment to rise.Yet one of its bendier bits is causing politicians to fret.Ed Miliband,the leader of the Labour Party,has promised a crackdown on"zero_hours contracts"if he wins the next election.The government has launched a consultation.Zero-hours contracts allow firms to employ workers for as few or as many hours as they need,with no prior notice.In theory,at least,people can refuse work.Fully l.4m jobs were based on these contracts in January 2014,according to a snapshot taken by the Office for National Statistics.That is just 4%of the total,but the share rises to a quarter in the hospitality business.The contracts are useful for firms with erratic pattems of demand,such as hotels and restaurants.They have also helped firms to expand during the recovery-allowing them to test new business lines before hiring permanent staff,who would be more costly to make redundant if things went wrong.Flexibility suits some workers,too.According to'one survey,47%of those employed on zero-hours contracts were content to have no minimum contracted hours.Many of these workers are in full-time education.The ability to tum down work is important to students,who want to revise（or sit in the sun）at this time of year.Pensioners keen for a little extra income can often live with the uncertainty of not having guaranteed hours.Yet that leaves more than a quarter of workers on zero-hours contracts who say they are unhappy with their conditions.Some of this is cyclical.During recessions,a dearth of permanent positions forces people into jobs with no contracted hours even if they do not want them（the govemment has just said that unemployed people who refuse to accept zero-hours contracts could be cut off from benerits）.Underemployment is particularly prevalent among these workers,35%of whom would like more hours compared with 12%in other jobs.As the economy recovers,many should be able to renegotiate their contracts or find permanent jobs.But the recovery will not cause unwanted zero hours contracts to disappear.Some workers will never have much negotiating power:they are constrained by geography,family commitments and lack of competition for their skills among a small number of big employers.Zero-hours contracts make it easier for employers to abuse their labour-market power.Some use them to avoid statutory obligations such as sick and maternity pay.Workers are penalised for not being available when requested.And some contracts contain exclusivity clauses which prevent workers from taking additionaljobs.These can harm other employers as well as workers,and actually reduce labour market flexibility.That,at least,is worth doing away with.
"Zero-hours contract"would be helpful for some firms in that_____.A.working hours for works should be agreed on
B.people can refuse work practically
C.it would bc less costly to cut jobs than hire permanent staff
D.it would cut cost to scale up the company
