A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults .

The researchers used a national long-term survey of adolescent（青少年的）health to investigate （调查）the relationship between media use and depression. They based their findings on more than four thousand adolescents who were not depressed when the survey began in 2000.

As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.

Seven years later, in 2007, more than seven percent of the young people had signs of depression. The average age at that time was twenty-one.

The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio, etc. But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression. Young men were more likely than young women to develop depression given the same amount of media use.

The study didn't explore if watching TV causes depression. But one possibility is that it was taking time away from activities that could help prevent depression.

Last December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, to attend religious services and to vote.

1.The best title for this passage should be____________.

　A. Teens, Television and Depression

　B. Men Develop Depression Easier than Women

　C. Media Use is Harmful to Adolescents

　D. Take Great Care of Teenager's Depression

2.The result of the research seems to prove______________.

　A. teenagers are more likely to develop depression than adults

　B. other media uses do no harm to adolescents

　C. TV probably causes teenagers to grow up with depression

　D. those who watch no TV will not develop depression

3.We can learn from the survey that of all the media use

　A. computer games are teenagers' favourite

　B. most teenagers prefer to listen to the radio

　C. teenagers enjoy watching TV very much

　D. newspaper is not included in the survey

4.We can conclude that a teenager should _____

　A. play more video games instead of watching TV

　B. be active in taking part in outdoor activities

　C. be more active in watching educational TV programmes

　D. attend religious services and care for politics

A new study suggests that the more teenagers watch television, the more likely they are to develop depression(情绪低落) as young adults.

The researchers used a national long-term survey of adolescent（青少年的）health to survey the relationship between media use and depression. They based their findings on more than 4,000 adolescents who were not depressed when the survey began in the year 2000.

As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.

Scientists at the University of Oxford have developed new artificial intelligence software to recognize the faces of chimpanzees in the wild. The new software will allow researchers to significantly cut back on time and resources spent analyzing video footage.

“For species like chimpanzees, which have complex social lives and live for many years, recording their behavior from short-term field research can only tell us so much.” says Dan Schofield, researcher and DPhil student at Oxford University’s Primate Models Lab. “By using the power of machine learning to unlock large video footage, it makes it feasible to measure behavior over the long term. Observing how the social lives of a group change over several generations become possible as well.”

The computer model was trained using over 10 million images from Kyoto University’s Primate Research Institute (PRI) video footage of wild chimpanzees in West Africa. The new software is the first to recognize individuals in a wide range of poses, performing with high accuracy in difficult conditions such as low lighting, poor image quality and movement blur (模糊).

“Access to this large video footage has allowed us to use cutting edge deep neural networks to train models at a scale that was previously not possible.” says Arsha Nagrani, co-author of the study and DPhil student in University of Oxford. “Additionally, our method differs from previous primate face recognition software in that it can be applied to raw video footage with limited manual intervention (人工干预) or pre-processing, saving hours of time and resources.”

The technology has potential for many uses, such as monitoring species for protection. Although the current application focused on chimpanzees, the software provided could be applied to other species, and help drive the adoption of artificial intelligence systems to solve a range of problems in the wildlife sciences.

“All our software is available open-source for the research community.” says Nagrani. “We hope that this will help researchers across other parts of the world apply the same cutting-edge techniques to their unique animal data sets. As a computer vision researcher, it is extremely satisfying to see these methods applied to solve real, challenging biodiversity (生物多样性) problems.”

“With an increasing biodiversity crisis and many of the world’s ecosystems under threat, the ability to closely monitor different species and populations using systems will be important for protection efforts, as well as animal behavior research.” adds Schofield. “Interdisciplinary cooperation like this have huge potential to make an impact, by finding solutions for old problems, and asking biological questions which were previously not available on a large scale.”

1.What’s the function of the new artificial intelligence software?

A.Analyzing video footage in difficult conditions.

B.Recognizing the faces of chimpanzees in the wild.

C.Cutting edge deep neural networks to train models at a scale.

D.Saving hours of time and resources without manual intervention.

2.What does the underlined word “feasible” in Paragraph 2 probably mean?

A.possible B.important

C.natural D.official

3.From the passage, we know that the artificial intelligence software could ________.

A.recognize individuals but not clearly

B.save time and resources only

C.help to protect different species

D.hardly solve biodiversity problems

4.What is the main purpose of the passage?
