Youth is a stressful time from friends to school to families, stressful situations become common. The body can respond (反应) with faster breathing, a fast bating heart, tense (绷紧的) muscles and drop of sweat. And teens who breathe polluted air appear to respond most strongly to stress, a new study shows.
Jonas Miller, a psychologist working at Stanford University ,studied whether or how air pollution might affect the body’s response to stress. Miller’s team invited 144 teens to participate in a stressful test. Most of the kids lived in or near San Francisco,which has the worst air quality.
Before the test, the researchers used sensors(感测器) to record heart rates and sweat levels for five minutes as the kids rested. Then as the test began, a researcher read aloud the beginning of a story and the kids had five minutes to make up an exciting ending to the story. They would have to memorize their ending and present it aloud to a judge. After fishing this task. the kids were asked to do math problems, which obviously was a harder task. If he or she made a mistake, the judge let the student start over. The whole time, sensors recorded heart rates and sweat levels.
Miller found all the students had similar heart rates and sweat levels at rest. But as the test got difficult, differences began to appear Kids from places with more air pollution responded more strongly to stress and their heartbeats became irregular. They sweated more than teens who lived in cleaner places.
"The teens' bodies were preparing to deal with possible challenges in the environment and such bodily responses to stress were linked to negative feelings", Miller concludes. Over time, he says, "these responses can contribute to both physical and mental health problems."
This study has proved the negative heath effects of air pollution among teenagers. Therefore, teenagers should try to avoid their exposure (暴露) to air pollution They should consider limiting their time outside during rush hour, especially on days when air pollution is particularly strong.

Salik, a 14-yearold boy, has become an overnight online star after a Malaysian visitor to the temples (寺庙) of Angkor in Cambodia posted a video on Facebook of him speaking 10 different languages. The post went viral throughout the country and many parts of Asia, throwing the spotlight on the boy.
Salik is one of many children selling simple gifts to tourists. But Salik has surprised visitors with his ability to talk in many foreign languages. His mostly self-taught skills are amazing. With this unusual talent, he earns more than other children. The money goes directly to his mother, who uses it to support Salik's as well as his brothers' education and the family's daily needs. Their home is just a few hundred meters from the famous temple Ta Prohm, and the family has struggled with debt.
Luckily, Salik's days as a temple seller could now be over. Rich businessmen and charities have promised thousands of dollars, donated new bicycles and toys, and agreed to support Salik's
education until he finishes university. With their support, he has made up his mind to further improve his language skills and general education. His dream is to become a tour guide when he finishes school, a dream close to his home and his heart, so he can travel to new countries.
Salik has that chance now while, sadly, most of the other children around him do not. In Cambodia, there are thousands of children on the streets, many of whom are forced to beg. Their
job is to be happy and smiling for the tourists, who feel sad for them and give them money, but that money doesn't go to the children. It goes to the men in control of the children and the begging business. Therefore, the best way to help children in Cambodia, and elsewhere, is''DON'T BUY FROM CHILDREN", according to Bruce Grant, Cambodia's Chief of Child Protection. He explains that the more a child earns, the more likely it is that he will continue to be forced to work.

Since the age of three, Chelsie Hill had dreamed of becoming a dancer. That dream nearly ended one night in 2010. Hill was in a car accident that put her in hospital for 51 days and left her
paralyzed (瘫痪). For most people, that would have destroyed any hope of a dancing career. For Hill, it was the beginning. Far from being a difficult, her wheelchair encouraged her to think a lot of her life and she wanted to prove that she was sill "normal".
"Normal" for her meant dancing. With half of her body taken away, Hill had to move it with hands. It took a lot of learning and patience, but she still made it in her wheelchair with her non-disabled high school dance team.
After graduation from high school in California, Hill wanted to expand (扩展) her dance network to include women like her. She met online the women who had suffered various back injuries but shared the same determination with her.
Hoping to reach more people in a larger city and break down the false belief of wheelchair users, Hill moved to Los Angeles in 2014, formed a team of dancers with disabilities and named it the Rollettes. As she always believes, dancing on wheels can be just as good as foot-based dance.
In disabled dance competitions, all dancers from her team gave great performances and they were having fun. And the audience's cheers, whistles and applause (掌声) suggested that the fun was spreading.
Hill has achieved what many of us never will: her childhood dream. But the Rollettes has helped her find something else just as satisfying. Every year she holds a dance camp, the Rollettes Experience for wheelchair users of all ages to help them find their inner heroines (女英雄). In 2019. over 173 women from ten countries attended the Rolettes Experience. For most of these women, it was the first time they had felt they belonged .Edna Serrano told a reporter that being part of the Rollettes team challenged her to be more independent. “It even gives me the courage to take up driving." she said.
