    Teens and younger children are reading a lot less for fun, according to a Common Sense Media report published Monday.

    While the decline over the past decade is steep for teen readers, some data in the report shows that reading remains a big part of many children's lives, and indicates how parents might help encourage more reading.

    According to the report's key findings, "the proportion (比例) who say they 'hardly ever' read for fun has gone from 8 percent of 13-year-olds and 9 percent of 17-year-olds in 1984 to 22 percent and 27 percent respectively today."

    The report data shows that pleasure reading levels for younger children, ages2-8, remain largely the same. But the amount of time spent in reading each session has declined, from closer to an hour or more to closer to a half hour per session.

    When it comes to technology and reading, the report does little to counsel(建议)parenst looking for data about the effect of e-readers and tablets on reading. It does point out that many parents still limit electronic reading, mainly due to concerns about increased screen time.

    The most hopeful data shared in the report shows clear evidence of parents serving as examples and important guides for their kids when it comes to reading. Data shows that kids and teens who do read frequently, compared to infrequent readers, have more books in the home, more books purchased for them, parents who read more often, and parents who set aside time for them to read.

    As the end of school approaches, and school vacation reading lists loom(逼近)ahead, parents might take this chance to step in and make their own summer reading list and plan a family trip to the library or bookstore.

    When a child is told he is "uncool", it can be very painful. He may say he doesn't care, and even act in ways that are different from cool on purpose(故意地）. But these are simple ways to deal with sadness by pretending it's not there.

    Helping a child feel better in school had to be careful. If you say, "Why are you worried about what other children think about you? It doesn't matter!" Children know that it does matter. Instead, an active way may be best. You could say, "I'm going to do a couple of things for you to help you feel better in school."

    If a boy is having trouble making friends, the teacher can help him. The teacher can arrange things so that he has chances to use his abilities to contribute to class things. This is how the other children learn how to value his good qualities and to like him. A teacher can also raise a child's popularity in the group by showing that he values that child. It even helps to put him in a seat next to a very popular child, or let him be a partner with that child in activities, etc.

    There are things that parents can do at home, too. Be friendly when your child brings others home to play. Encourage him to invite friends to meals and then serve the dishes they consider "super" .When you plan trips, picnics, movies, and other shows, invite another child with whom your child wants to be friends.

    What you can do is to give him a chance to join a group that may be shutting him out. Then, if he has good qualities, he can start to build real friendship of his own.

    The audiences of the UK will have an opportunity to enjoy a feast of Chinese culture when the China National Peking Opera Company returns to the country for the fourth time for a series of workshops and performances. Events will be held at the British Library, Oxford's Ashmolean Museum and the world-famous dance theater of Sadler's Wells, featuring artists including Lisa Lu, Yu Kuizhi and Li Shengsu.

    On Thursday at the British Library, Lisa Lu, who also played a role in recent cinema hit Crazy Rich Asians, will lead a group of artists from China, the US and the UK to discuss their experiences of working across a variety of artistic fields in different cultures over many decades.

    The series of activities also include interactive workshops, which explain the intricacies（错综复杂）of the attractive art of Peking Opera. The secrets behind a great opera, from music to instruments, from make-up to martial arts, will be revealed at the British Library workshops on Saturday and Sunday.

    Events end on Oct 19 and 20 at Sadler's Wells in North London, with two performances of The Emperor and the Concubine, one of the most celebrated operas, as well as The Crossroads Inn and The Monkey King and The Leopard.

    Li Shengsu, who led the cast of The Emperor and the Concubine, explained that the show is the beautiful love story championed by Peking Opera Master Mei Lanfang, and it is one of the very few works from the Master Mei's that had been handed down since 1920s.

    The productions are being presented in partnership with London-based Sinolink Productions, a company that promotes Chinese art, culture and performance to British audiences.

    Zhang Kewei, producer and director of Sinolink, said, “It is delightful to see that the China National Peking Opera Company returns to London for the fourth time with another two masterpieces this year. The performances so far have received very positive comments from audiences and the United Kingdom's media and we are looking forward to further expanding our program.”

    Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer (癌症)?

    People have been wondering why elephants do not develop cancer, even though they have lifespans (寿命) that are similar to humans, living for around 50 to 70 years.

    Now scientists believe they know why. A team at the University of Chicago, US has found that elephants carry a large number of genes that stop tumors (肿瘤) from developing. To be precise, they found 20 copies of an anti­tumor gene called TP53 in elephants. Most other species, including humans, only carry one copy.

    According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal's sensitivity to DNA damage. This lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors.

    “An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals，” study author Dr. Vincent Lynch told The Guardian. If every living cell (细胞) has the same chance of becoming cancerous, large creatures with long lifespans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass.

    This_phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named "Peto's paradox". Evolutionary (进化的) biologists believe it results from larger animals using protection that many smaller animals do not. In the elephant's case, the making of TP53 is nature's way of keeping this species alive.

    The study also found that when the same genes were brought to life in mice, they had the same cancer resistance (抵抗) as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place.

    "Nature has already figured out how to prevent cancer, " said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US.

    “It's up to us to learn how different animals tackle (处理) the problem so we can use those strategies to prevent cancer in people.”

    Dr Dian Fossey, one of the world's leading women scientists, had a remarkable career. The work she devoted her life to protecting and studying the mountain gorillas (大猩猩) of Africa—has proved highly effective and has resulted in the steady (平稳的) increase of this most endangered great apes.

    Fossey made her first trip to Africa in 1963. Three years later, she returned to Africa to begin a long term study of the mountain gorillas. She set up camp in the Democratic Republic of Congo but moved to Rwanda because of political reasons in 1967. She established her "Karisoke" Research Centre camp on September 24, 1967.

    Fossey's aims were to study gorilla ecology (生态学) and social organization. She found that in order to achieve this, she needed to recognize individual gorillas, which required that the gorillas get used to her presence (出现). By copying gorillas' behaviour and sounds, Fossey began to gain their trust, and in 1970 an adult male gorilla she had named "Peanuts" reached out to touch her hand.

    Close observations over thousands of hours enabled Fossey to gain the gorillas' trust and bring forth new knowledge about their behaviour. Stories and photographs of her work were published in National Geographic Magazine and elsewhere.

    In 1977, one of Fossey's favorite gorillas, Digit, was killed by poachers and she established the Digit Fund to help raise money for gorilla protection efforts in the same year.

    On December 26, 1985, Fossey was murdered while going back to her house in Karisoke. Her body was discovered near the research centre. Most probably? Dian Fossey had been killed by the poachers she'd fought against. On her tombstone (墓碑): "No one loved gorillas more..."

    In 1988, the life and the work of Fossey were made into a movie based on her book.
