Findings suggest that playing with smartphones before sleep {#blank#}1{#/blank#}(be )positively associated  with insomnia(失眠症). Recent {#blank#}2{#/blank#}(study) show that nearly 24 percent of Chinese people suffer from insomnia and {#blank#}3{#/blank#}number of young people affected is rising. And more than 60percent of people born after 1990,the group that are most likely{#blank#}4{#/blank#}(use) their smartphones just before sleep, do not sleep well.

    Bedtime mobile phone use is an unhealthy sleep habit because{#blank#}5{#/blank#}can delay falling asleep and reduce sleep quality. According to the research, nearly three-quarters of the young people fall asleep each night with their phones {#blank#}6{#/blank#}reach. About 60 percent of them use their smartphones for up to 80 minutes before sleep. And 54.7 percent of the people aged between 18 and 25 go to bed{#blank#}7{#/blank#}(late) than 12 am.

    Good sleep is helpful in protecting the brain's neurons(神经元)and lack of sleep for long periods can{#blank#}8{#/blank#}(danger) health. Therefore, all people, including the young,{#blank#}9{#/blank#} (advise) to avoid using electronic devices one hour before sleep and go to bed at fixed times. But it is{#blank#}10{#/blank#}(benefit) to sleep if people listen to soft music and read books before going to bed.

    Henry Bond was about ten years old when his father died. He lived {#blank#}1{#/blank#} poor life with his mother. When in fourth grade, Henry wanted a grammar book in order to join a class in the school. But his mother didn't have money {#blank#}2{#/blank#} (buy) one for him. {#blank#}3{#/blank#}(trouble) by it, Henry started thinking about {#blank#}4{#/blank#} could be done.

    One morning, it snowed {#blank#}5{#/blank#} (heavy) and the cold wind blew hard. {#blank#}6{#/blank#} (look) at the deep snow, Henry said to {#blank#}7{#/blank#} (he), “It is an ill wind that blows nobody good.”

    He ran to the house of a neighbor, and offered his services to clear a path in front of his house. The offer was accepted. After {#blank#}8{#/blank#} (complete) this work, he received a tip. Then he went to another place for the same purpose, and then to another, until he earned enough to buy the book.

    When school {#blank#}9{#/blank#} (start), Henry was in his seat, the happiest boy in the class, ready to begin the lesson in his new book.

    Henry was always one of the top students in his class. He knew no such word {#blank#}10{#/blank#} “fail”. Having the will, he always found the way.

    What on earth does happiness mean? I can't give you its exact definition, but I'm sure if you love and help others, you'll get it.

    I'll never forget {#blank#}1{#/blank#}old lady. She lives in a small house alone. It is said that her husband and her son died in a road accident years ago. Her life is bitter, {#blank#}2{#/blank#} she often helps others with a smile. Whenever{#blank#}3{#/blank#} snows, she is always the first to clean the paths. She looks after several children {#blank#}4{#/blank#} (live) nearby. I am one of them. I often remember the stories she told us and her kind smile. Perhaps she is unlucky, but I think she is a happy person. Her life is full of{#blank#}5{#/blank#} （laugh）and love.

    But I'm sad to see some people getting their happiness {#blank#}6{#/blank#}bad ways. They talk {#blank#}7{#/blank#}（noisy）in cinemas and meeting rooms; they destroy trees to enjoy themselves and they laugh at others' shortcomings. Perhaps they feel happy at that time, but they will never get true happiness because they {#blank#}8{#/blank#}（lose）their personality already.

    Now I know {#blank#}9{#/blank#} happiness is. It means kindness, love and unselfishness. Above all, I have come to understand that bringing happiness to others {#blank#}10{#/blank#} (be) getting ourselves happiness.

    In northeastern Liaoning Province, winter can be very cold. For months, almost nothing grows on these frozen areas, except for one {#blank#}1{#/blank#} (surprise) product—grapes, which make something special, ice wine. Ice wine {#blank#}2{#/blank#} (make) from frozen grapes. The freezing process gives the wine a sweet flavor. It's so much {#blank#}3{#/blank#} (strong). It tastes like a raisin (葡萄干).

    Here, conditions for making ice wine are so perfect {#blank#}4{#/blank#} a third of the world's ice wine is now produced here. Strict rules mean that the temperature must be at least -8℃ for hours. While they wait, the grapes could go bad. So, {#blank#}5{#/blank#} (prevent) this from happening, they need to be picked as soon as the conditions {#blank#}6{#/blank#} (be) right.

    In the early morning, the villagers are all {#blank#}7{#/blank#} (die) to help. The grapes planted here are called Vidal. As soon as the grapes are picked, they are transported to the wine company—the largest {#blank#}8{#/blank#} (produce) in China. Two years later, the wine is ready to be in the bottles, each of {#blank#}9{#/blank#} contains the juice of a 2.5 kilograms of grapes. These bottles will be{#blank#}10{#/blank#} the dinner table across China and even the world.

    The falling stars challenge, which began in Russia, invites participants{#blank#}1{#/blank#}(share) their best fake fall and recommend their friends to do the same, and people have been going to make their falls as dramatic as possible. At first, the falling stars challenge{#blank#}2{#/blank#}(regard) as a way for the wealthy to show their{#blank#}3{#/blank#}(possession). People were photographing themselves falling from cars, boats and even their own private jets,{#blank#}4{#/blank#}(lie) face-down with luxurious jewelry, expensive items from high-end brands surrounding them.

    However, as the challenge spread, it transformed from being a way of showing off to a creative way to show {#blank#}5{#/blank#}people consider important in their lives. The social media craze soon made{#blank#}6{#/blank#}(it) way to Weibo, a Chinese social media platform. A major difference with the Chinese version of the challenge {#blank#}7{#/blank#}(be) that professionals from different industries participated to show their daily routine. These include a firefighter lying in front of a row of fire trucks and {#blank#}8{#/blank#}officer at an emergency call center on the ground with documents thrown in all directions.

    While some pictures are intended {#blank#}9{#/blank#}fun online, Chinese authorities are taking it {#blank#}10{#/blank#} (serious). Some people who have participated in the trend have received tickets for breaking traffic laws to get the perfect photo.

    It's difficult to say exactly when IWD(International Women's Day) began. It dates back to 1908, {#blank#}1{#/blank#} 15,000 women marched through New York City demanding voting rights, better pay and {#blank#}2{#/blank#}(short) working hours.

    A year later, the first National Woman's Day {#blank#}3{#/blank#}(allow) in the US on February 28, according to an announcement by the Socialist Party of America.

    In 1910, a woman {#blank#}4{#/blank#}(call) Clara Zetkin—leader of the "women's office" for the Social Democratic Party in Germany came up with the idea of International Women's Day. She suggested that every country {#blank#}5{#/blank#} (celebrate) International Women's Day on one day every year to push for their demands.

    A meeting of more than 100 women from 17 {#blank#}6{#/blank#}(country) agreed to her suggestion and IWD was formed. In 1911, it was celebrated for {#blank#}7{#/blank#} first time in Austria, Denmark, Germany and Switzerland {#blank#}8{#/blank#} March 19.

    In 1913, it was decided {#blank#}9{#/blank#}(change) IWD to March 8, and it has been celebrated on that day ever since. The day was only recognized by the United Nations in 1975. It {#blank#}10{#/blank#}(create) a theme (主题) each year for the celebration ever since.
