Lights out, phones on. Many teenagers reach for their smartphones or tablets at bedtime, but it may be a good idea to switch off before you hit the pillow.

    According to a study by researchers at Murdoch and Griffith Universities in Australia, using mobile devices late at night could harm teenagers' sleep and lead to an increased risk of mental health problems.

    The study was carried out on more than 1,000 Australian high school students aged between 13 and 16. It lasted four years as student participants moved from Year 8 to Year 11.

    During the study, students were asked what time of the night they received or sent text messages and phone calls, and how well they slept.

    The results are impressive. When the study started in Year 8, more than 85 percent of the students had a mobile pone and around one-third of these students never used phones after lights out. In contrast, 93 percent of Year 11 students had a mobile phone and only 22 percent of then had no late night mobile use when the study concluded four years later.

    As the levels of mobile phone use increased, there was a growth in poor sleep behavior among the students. Meanwhile, mental health problems also increased. Students in Year 8 who were more likely to use phones at night were found to have higher levels of depression (抑郁) and lower self-esteem (自尊心) one year later.

    Lynette Vernon, lead author of the study, explained that phones affect our sleep patterns because of the unnatural blue light they produce. This light could affect the level of hormones (荷尔蒙) in the body, disrupting (打乱) its balance.

     “The more you sit in bed and watch TV, play with your tablet, and play with your phone at three o'clock in the morning, the more these things affect the slow waves of your sleep pattern and give your poor quality sleep,” Mark Levi, a Sydney-based sleep doctor said.

    Based on the findings, the researchers suggested parents should focus on guiding their children's use of mobile devices.

    According to Vernon, the solution is not simply to ban teenagers from using their devices, but teach them better ways of using them

     “Back when they're aged 7 to 10, you have to be a role model. If you put your phone away at night and it doesn't go into your bedroom, it becomes normalizedin the household and you have a much easier job,” he told The Guardian.

    An Indian movie about two sisters has become a huge hit in China. The Hindi language film, called Dangal, has earned almost $ 170 million in China since its release there on May 5.

    Much has been written about why Dangal has enjoyed such big success in China. Some people say one reason is that the film's star and producer, Aamir Khan. He is famous in India's Bollywood film industry. Two of his earlier films were also big hits in China.

    Khan's popularity was clear after he got more than 600,000 followers on the Chinese social media service Sina Weibo within two months of joining. But he is not the only reason that the film strongly connects with audience across China. Media has pointed out how it shows similarities between parental systems in China and India.

    Dangal is based on the true story of a man who enjoyed the sport of wrestling (摔跤). He competed as a wrestler, but never could achieve his lifelong dream: winning a gold medal. As a father, he wanted his son to win the medal. But his wife only gives birth to daughters. So he finally decides to train them to be world-class wrestlers.

    The movie is more serious than most Bollywood productions, which tell happy love stories and include colorful music and dance performances.

    Edward Chan is a professor at the Hong Kong Polytechnic University. He says the strict way of parenting in the film is something people in China can easily relate to. “I think the father role described by the movie in India is quite similar to the culture, especially the traditional culture in China.”

    The Chinese government-supported Global Times newspaper pointed that movie critics (评论家) in China did not like Dangal. Most of them agree with the fact that the father in the film was forceful in pushing his daughters to become wrestlers. But the film Dangal is really aimed to educate children to work for their dreams.

    One of the most striking findings of a newly research in the UK is that of the people interviewed, one in two believes that it is becoming more difficult to meet someone to start a family with.

    Why are many finding it increasingly difficult to start close relationships? Does modem life really make it harder to fall in love? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for money or status. A man doesn't expect his wife to be in (唯一的) charge of running his household and raising his children.

    But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence.

    In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soul mate was limited by geography, social convention and family tradition. Although it was never clear，many marriages were essentially arranged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster ( 牡蛎), you surely have a better chance of finding a pearl.

    But it seems that the old conventions have been replaced by the limitations of choice. The expectations of partners are raised to an unmanageable degree: good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression.

    We think that a relationship can be perfect. If it isn't, it should be ended. We work to protect ourselves against future heartache and don't put in the hard emotional labor needed to build a strong relationship. Twelve-hour work at the office makes relaxed after-hours dating difficult. The cost of housing and child-raising creates pressure to have a stable income and Career before a life partnership.

    Every new person added to the planet needs food, water, clothes, and so on.{#blank#}1{#/blank#}. Those things require extra natural resources，including land and water. But Earth's riches are limited. Less than 1 percent of Earths water can be used for drinking and washing. One out of every thirteen people around the world does not always have enough clean water. {#blank#}2{#/blank#}. Too many people are using too much water, especially in the already dry areas of the southwestern United States.

    Food shortages(不足)are even more common. Worldwide, one out of every seven people does not get enough to eat. {#blank#}3{#/blank#}. Over time, the soil loses its nutrients (营养）and the farmland becomes useless for growing food. As the world becomes more crowded (拥挤的）， more land is needed to make way for growing cities.{#blank#}4{#/blank#}. That's a problem because trees help take in a gas called carbon dioxide. Humans produce carbon dioxide by burning coal and oil. Fewer trees mean more carbon dioxide in the atmosphere. The buildup of carbon dioxide traps heat and pollution above Earth.

    {#blank#}5{#/blank#}, although every person uses the planet's resources. The richest billion people, Americans especially, use the most resources. They also produce the most waste.

A. Forests are cleared away

B. Some people use a lot more than others

C. Water shortages have hit many parts of the world

D. Water pollution is a serious problem in some areas

E. More trees should be planted to handle air pollution

F. Huge needs for food force farmers to overuse their land

G. More people mean more cars, roads, schools, hospitals, and stores

Why Do We Find It Hard to Say "No"?
