Your teenage best friend could be good for your long-term mental health，according to a new study published in the journal Child Development According to the findings, teenagers aged 15 to 16 who had a close friendship rather than a larger group of friends they were less close to had a greater sense of self-worth by the time they were 25 years old. Those people with a very close best friend were also less likely to experience depression and social anxiety, the study found．
“Close friendship strength in mid-adolescence predicted relative increases in self-worth and decreases in anxiety and depressive symptoms by early adulthood，”the authors, led by Rachel K, Narr，a postdoctoral student focused on clinical psychology at the University of Virginia, wrote.
A past research has suggested that adolescent friendships are important. Friendships during the teenage years predict academic success and improved mental health. But the new research further explores the type of friendships teenagers have. “My hunch（预感）was that close friendships compared to broader friendship groups and popularity may not function the same way,” Narr told Quartz. "Being successful in one is not the same as being successful in the other."
Many study participants did not continue to have a close relationship with their high-school best friend, leading the researchers to wonder what exactly was responsible for the mental health benefits. They suspected that the skills and ability to build such a friendship may be more important than the friendship itself.
And as the researchers point out, those skills are not necessarily brought to bear in the world of social media. "As technology makes it increasingly easy to build a social network of shallow friends, focusing time and attention on developing close connections with a few individuals should be a priority," study co-author Joseph Allen said in a statement.
1.What is the benefit of having a close teenage friendship?
A.Excellent performance in high school. B.A larger group of friends.
C.Mental health by early adulthood. D.A large social network in the future.
2.What can we learn about the past research?
A.It attached great significance to adolescent friendships.
B.It was totally different from the new research.
C.It helped improve teenagers' mental health.
D.It compared broader friendship groups with popularity.
3.What did the researchers think might lead to the mental health benefits?
A.Not continuing to have a close relationship. B.Having a best friend in high school.
C.Understanding the world of social media. D.Knowing how to build a close friendship
4.What did the researcher Joseph suggest?
A.Learning to use social media.
B.Broadening your social circle.
C.Improving the skills of making friends.
D.Concentrating on high-quality relationship.

According to a team of researchers, an animals' ability to perceive(感知)time is linked to their pace of life.
"Our results lend support to the importance of time perception in animals where the ability to
perceive time in a very short time may be the difference between life and death for fast moving
creatures." commented lead author Kevin Healy from Trinity College Dublin.
The study was done with a variety of animals using a phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans.
One example of this phenomenon at work, the authors say, is the housefly and its ability to avoid being hit. The research showed flies "observe motion in a shorter time than our own eyes can achieve," which allows them to avoid being hit.
Professor Graeme Ruxton of the University of St Andrews in Scotland, who worked jointly(共同地) on the research project, said in a statement, "Having eyes that send updates to the brain at much higher frequencies than our eyes do is of no value if the brain cannot process that information equally quickly. Thus, this work highlights the impressive abilities of even the smallest animal brains. Flies might not be deep thinkers, but they can make good decisions very quickly."
In comparison the tiger beetle(虎甲虫)runs faster than its eyes can keep up, basically becoming blind, which requires it to stop periodically to re-evaluate its prey's(猎物)position.
Our results suggest that time perception offers an as yet unstudied dimension along which
animals can specialize and there is considerable range to study this system in more detail.
1.What is the research mentioned in the passage mainly about?
A. Pace of life of animals. B. Time perception of animals.
C. Lifetime of small animals. D. Impressive abilities of animals.
2.Why can houseflies avoid being hit?
A. They can think very deeply before they act.
B. They can fly much faster than their eyes can keep up.
C. They can process the information as quickly as they receive it.
D. They can send information to brain more quickly than to their eyes.
3.What will a tiger beetle have to do to catch a moving prey?
A. Try to run as fast as it can. B. Prevent itself from becoming blind.
C. Slow down to gain its time perception. D. Stop occasionally to spot the prey again.

Losing an arm means losing the ability to grab, as well as losing the sense of touch. Scientists have been working on mind-controlled prostheses (义肢) and have successfully built a few to help patients regain their ability to grab. But restoring the sense of touch has been quite a challenge – until now.
Seven years ago, a group of Swedish scientists created a new type of prostheses, which has since then been tried out on three patients to see how they perform in people’s daily lives. The study result was recently published in the New England Journal of Medicine.
According to the study, this is the first time that people who have had an arm amputated (截肢) can experience sensations of touch in mind-controlled arm prostheses.
The new product is named “neuromusculoskeletal” prosthesis. As the name indicates, the prosthesis is connected directly to a user’s nerves, muscles and skeleton. The sensation of touch becomes possible by stimulating nerves that used to be connected to the biological hand before the amputation.
When a patient grabs an object, for example, force sensors planted in the prosthetic thumb would measure contact and pressure. The collected information would then be transmitted to the patient’s nerves that lead to the brain. In this way, the patient can “feel” the characteristics of the object being touched and perceive (感知) its pressure against the prosthetic hand, which can be crucial when handling delicate objects – an egg, for example.
“The ability of the patients to discern (觉察) smaller changes in the intensity of sensations has improved,” Max Ortiz Catalan, Associate Professor at Chalmers University of Technology, Sweden, who is the leader of the study, told Science Daily.
According to Catalan, the new study has demonstrated that their prosthesis is qualified as a “clinically viable replacement for a lost arm”.
“The sensors are not the obstacle for restoring sensation,” Catalan added. “The challenge is creating neural interfaces (接口) that can seamlessly (无缝地) transmit large amounts of artificially collected information to the nervous system, in a way that the user can experience sensations naturally and effortlessly.” And they did it.
With the development of prosthesis technology, people who suffer from limb loss will have a greater chance of getting their normal lives back.
1.Neuromusculoskeletal prosthesis’ unique advantage is helping people with arm amputations to _____ .
A.carry heavy objects again B.regain the ability to grab objects
C.move their prostheses as they wish D.experience the sense of touch again
2.The new prosthesis is connected directly to __________.
① user’s nerves ② user’s brains ③ user’s muscles ④ user’s skeleton
A.① ② ③ B.① ③ ④ C.② ③ ④ D.① ② ④
3.How do the new prostheses work?
A.They collect information about objects and process it.
B.They stimulate the cut nerves to restore the sense of touch.
C.They measure the size of objects and send the information.
D.They detect the material of objects and send the information.
4.What can patients perceive with the new prosthesis?
A.The intensity of an object. B.The structure of an object.
C.The pressure from an object. D.The changes inside an object.
5.What is the difficulty in developing the new technology?
A.Measuring the pressure of objects. B.Connecting the sensors to nerves.
C.Creating good neural interfaces. D.Building responsive sensors.
6.What’s the author’s attitude towards the prospect of prosthesis technology?
A.Optimistic. B.Neutral.
C.Critical. D.Unconcerned.
