“Educational researchers, political scientists and economists are increasingly interested in the characteristics and skills that parents, teachers and schools should foster in children to increase chances of success later in life,” said lead author Marion Spengler, PhD of the University of Tubingen.” Our research found that specific behaviors in high school have long-lasting effects for one’s later life.”

Spengler and her co-authors analyzed data collected by the American Institutes for Research from 346, 660 U. S. high school students in 1960, along with follow-up data from 81,912 of those students 11 years later and 1,952 of them 50 years later. The initial high school phase measured a variety of student behaviors and attitudes as well as personality characteristics, cognitive abilities, parental socioeconomic status and demographic(人口统计的)factors. The follow-up surveys measured overall educational attainment, income and occupational prestige(声望).

Being a responsible student, showing an interest in school and having fewer problems with reading and writing were all significantly associated with greater educational attainment and finding a more prestigious job both 11 years and 50 years after high school. These factors were also all associated with higher income at the 50-year mark. Most effects remained even when researchers controlled parental socioeconomic status, cognitive aibility and other broad personality characteristics such as conscientiousness.

While the findings weren’t necessarily surprising, Spengler noted how reliably specific behaviors people showed in school were able to predict later success.

Further analysis of the data suggested that much of the effect could be explained by overall educational achievements, according to Spengler.

“Student characteristics and behaviors were rewarded in high school and led to higher educational attainment, which in turn was related to greater occupational prestige and income later in life,” she said. “This study highlights the possibility that certain behaviors at crucial periods could have long-term consequences for a person’s life.”

1.What’s the finding of Marion Spengler’s research?

A. Teachers play a decisive role in students’ later success

B. Personality characteristics are more important than academic performances

C. Higher educational attainment has little to do with occupational prestige

D. Behaviors in the high school should be highly stressed.

2.Which is TRUE about the research?

A. The research was conducted among totally different people during different periods

B. The research was based on the data collected from 1960 to 2010

C. More people were involved in the follow-up surveys

D. The initial high school phase measured attitudes only

3.What is likely to contribute to later success according to the research?

A. Parental socioeconomic status

B. Overall educational achievements

C. Cognitive ability

D. Hard work

4.Why did the researchers control some factors like parental socioeconomic status?

A. To avoid the previous mistakes

B. To highlight the effects of certain specific behaviors

C. To draw an immediate conclusion

D. To hid some negative findings

Researchers around the world interested in uncovering complex human disorders, such as Alzheimer’s disease, could soon have access to cloned monkeys with genomes that have been edited to display these conditions in China.

On 24 January, scientists at the Institute of Neuroscience (ION) in Shanghai reported that they had used gene-editing to disable a gene in monkeys that is crucial to their sleep- wake cycle. The scientists then cloned one of those monkeys to produce five primates (灵 长目动物)with almost identical (相同的) genes. It is the first time that researchers have cloned a gene-edited monkey.

Primates are the best animal model for studying higher cognitive (认知的)functions and brain disorders in humans, says neuroscientist Mu-ming Poo, ION’S director and co-founder of the new 720 million yuan (US$106 million) centre. The advantage of creating cloned monkeys is that it reduces the number of animals needed for certain types of experiments, such as testing whether a drug works.

But some scientists think that experiments using monkeys should be a last approach because of their higher levels of cognition. Mitchell Lazar, who studies metabolic disease at the University of Pennsylvania, says that some experiments in mice—for example, research into the genes behind human diseases—are equally appropriate scientifically as in primates. Research in mice is also more accepted by the public, and the animals are cheaper and quicker to produce. Lazar worries that if scientists have ready access to populations of gene-edited monkeys, they might use them for experiments when rodents (啮齿动物)would do.

Poo says that mice are not a good substitute for studying higher cognitive functions and brain disorders in humans. He argues that cloning will reduce the burden on monkeys by cutting the number used in labs. The ION follows strict international guidelines for animal research, he says.

Poo’s team will continue to study the effect of gene editing on their five cloned monkeys. The group disabled a gene, BMAL1, that has a crucial role in maintaining circadian rhythm (生理节奏)，the internal clock that helps a healthy sleep-wake cycle. In people, BMAL1 mutations have been linked to diabetes, hypertension and depression.

The monkeys with the disabled BMAL1 genes move more at night and sleep less overall. They also display psychosis-related symptoms, such as fear and anxiety, when put in unfamiliar environments.

The team ’ s next step is to look in detail at the neural (神经的)mechanisms that might create these problems. It will also take advantage of the genetically identical monkeys to hunt for diagnostic markers of circadian rhythm-related disorders and possible treatments.

1.Why were the genetically identical monkeys cloned?

A. To prove scientists’ innovation in cloning animals.

B. To study the rare characteristics of cloned monkeys.

C. To explore many possibilities for monkeys’ cognition.

D. To provide improved animal models of human diseases.

2.What does Mitchell Lazar think of cloning monkeys?

A. It is of little value.

B. It is of much practice.

C. It is hardly acceptable.

D. It is completely illegal.

3.From the passage we can know that Poo’s team will .

A. continue to disable a gene on the monkeys

B. try to clone more monkeys and edit their genes

C. find the similarities between humans and monkeys

D. determine the cause of sleep disorders and find cures

4.What’s the main idea of the passage?

A. Chinese effort to clone gene-edited monkeys kicks off.

B. Chinese dream to clone monkeys has finally come true.

C. Cloning monkeys is an important breakthrough in science.

D. Cloning gene-edited monkeys has caused some moral risks.

Following the crowd may not always be in a person’s best interest.But new research suggests that teens who go along with their friends may end up healthier as adults.

Scientists have known that close friendships help boost health.That’s true for both teens and adults.The finding inspired Joseph Allen,a psychologist at the University of Virginia,and his team to study whether experiences during teen years would influence adult health.So they followed 171 teens,starting when the kids were just 13.They interviewed each one every year for five years,and also spoke to these teens’ closest friends,who provided additional information about the quality of their friendships.The same 171 people were interviewed again at ages 25,26 and 27. This time,the questions surveyed each person’s overall health.When the researchers analyzed the data they found a strong connection between a teen’s behavior and adult health.Teens who had close friends grew up to be the healthier adults.Whether teens held back their feelings or expressed them to a close friends also influenced later health.Those who held back were more likely to be sick as adults.The connection held up even after the scientists accounted for other possible influences on health.Weight,family income and drug use were all examined.So were mental health issues,such as anxiety and depression.And in these people,such other factors did not explain adult health as well as teen friendships did.

Going along with the crowd may have benefits,says Allen,but there are also drawbacks.Teens who are more independent tend to do better at school and work.And peer pressure may lead some kids to engage in risky behavior, such as smoking,drinking or using drugs.Dealing with it is an ongoing challenge,Allen acknowledges.“Finding the right balance is the key.Teens shouldn’t lose heart for not finding this easy.”And,he adds,“Parents need to be understanding about the pressures teens face.”

A. in order to do better at school,teens should not follow the crowd

B. though it’s challenging for teens to deal with peer pressure,they should not give up

C. teens will engage in smoking,drinking or using drugs when facing peer pressure
