According to a recent survey,violence did exist in schools. Students {#blank#}1{#/blank#} (show) their fear and parents and teachers also expressed their great concern about it. {#blank#}2{#/blank#} (expert) hope the whole society will pay more attention to the mental health of adolescents.

    Nowadays, school violence is {#blank#}3{#/blank#} hot issue. I think this is a phenomenon（现象）, {#blank#}4{#/blank#} calls for our great concern.We should try every effort {#blank#}5{#/blank#} (prevent) violence happening at school for more and more students would drop out of school if their personal {#blank#}6{#/blank#} (safe) could not be guaranteed.In fact,violence can be learned.Children learn violent behavior from adults or from {#blank#}7{#/blank#} they see on television or on the Internet.

    If I meet with school violence,I will not answer violence {#blank#}8{#/blank#} violence, for it will result in {#blank#}9{#/blank#} (much、fighting.I will tell my teachers or parents about it.I think they will help me deal with it well and they will protect me from the bad guys.

    All in all, every student should behave {#blank#}10{#/blank#} (he) and keep away from violence.

    In much of Asia, especially the stalled “rice bowl” cultures of China, Japan, Korea,{#blank#}1{#/blank#} Vietnam, food is usually eaten with chopsticks.

    Chopsticks are usually two long, thin pieces of wood or bamboo. They can also be made of plastic, animal bone or metal. Sometimes chopsticks are quite artistic. Truly elegant chopsticks might{#blank#}2{#/blank#} (make) of gold and silver with Chinese characters. Skilled workers also combine (结合) various hardwoods and metal{#blank#}3{#/blank#}(create) special designs.

    The Chinese have used chopsticks for five thousand years. People probably cooked their food in large pots,{#blank#}4{#/blank#} (use) twigs (树枝) to remove it. Over time,{#blank#}5{#/blank#}the population grew, people began cutting food into small pieces so it would cook more quickly. Food in small pieces could be eaten easily with twigs which{#blank#}6{#/blank#}(gradual) turned into chopsticks.

    Some people think that the great Chinese scholar Confucius,{#blank#}7{#/blank#} lived from roughly 551 to 479 B.C., influenced the{#blank#}8{#/blank#}(develop) of chopsticks. Confucius believed knives would remind people of killings and {#blank#}9{#/blank#} (be) too violent for use at the table.

    Chopsticks are not used everywhere in Asia. In India, for example, most people traditionally eat{#blank#}10{#/blank#} their hands.

    Young sunflowers face the sun as it rises in the east and follow it across the sky until it sets in the west. Why does this happen? A team of scientists has finally been able to figure{#blank#}1{#/blank#} how and why young sunflowers move.

    Older sunflowers always face east. However, as it{#blank#}2{#/blank#}(turn) out, an internal（内部的）clock helps young sunflowers track the sun so that they can grow better. US biologist Stacey Harmer and her colleagues had it{#blank#}3{#/blank#}(explain) in a recent paper published in the journal Science on Aug. 5.

    {#blank#}4{#/blank#}(depend) on the time of day, certain growth genes seem to work to different degrees on different{#blank#}5{#/blank#}(side) of young sunflowers' stems（茎）. The east side of their stems grows faster during{#blank#}6{#/blank#}day, causing the stems to {#blank#}7{#/blank#}(gradual) bend from east to west. The west side grows faster at night, preparing them for the next morning.

    All this move is highly{#blank#}8{#/blank#}(benefit) to sunflowers. The team found that flowers kept away from the sun had leaves{#blank#}9{#/blank#}were 10 percent smaller on average. According to Harmer, sunflowers which{#blank#}10{#/blank#} (face) with the sun receive more bees and other insects because they like warm flowers.

    A humanoid named Sophia has made history {#blank#}1{#/blank#}becoming the first robot in the world with citizenship. Journalist Andrew Ross Sorkin made the announcement at the end of an interview with Sophia.

    “We just learned, Sophia, I hope you're listening to me, that you have been now awarded {#blank#}2{#/blank#} is going to be the first Saudi citizenship for a Robot,” he said to applause from the audience.

    Sophia responded, without missing a beat: “I want to thank very much the kingdom of Saudi Arabia.”

    “I am very proud and honored {#blank#}3{#/blank#}(award) citizenship and I simply appreciate {#blank#}4{#/blank#} (recognize) with citizenship as a robot, which is historical .” the robot said.

The pair discussed the future of artificial intelligence, {#blank#}5{#/blank#}Sophia said it wants to use to “help humans live a better life.”

    Sorkin expressed concerns {#blank#}6{#/blank#}(previous) raised by Elon Musk that artificial intelligence could be dangerous if it {#blank#}7{#/blank#} (go) evil and turned on humanity. But Sophia insisted it wanted to use artificial intelligence only to "help humans live a better life."

    Sophia tried to remove Sorkins' fears of {#blank#}8{#/blank#}"bad future," insisting that AI is "designed around human values like {#blank#}9{#/blank#}(wise), kindness, compassion."

    It accused him of "reading too much Elon Musk," and said, "don't worry, if you're nice to me, I{#blank#}10{#/blank#}(be) nice to you. Treat me as a smart input-output system."

    The way you walk may be determined by your daily schedule, and it may also reflect your personality. The {#blank#}1{#/blank#} (choose) you make can tell something about your inner thoughts. At least, that's {#blank#}2{#/blank#} science has proved. Lately, researchers {#blank#}3{#/blank#} (observe) the way that people walk and how it relates to their personalities. Available online via Sage Journals, the study examines both the walking styles and personalities of 15, 000 adults aged from 25 to 50. According to the study, when {#blank#}4{#/blank#} (face) with the new challenges, fast walkers are more likely to be active while quiet people tend to walk more slowly. Meanwhile, the study has also found {#blank#}5{#/blank#} (power) evidence that walking speed in adulthood reflects the individual's personality. However, speeding up your walking pace can't {#blank#}6{#/blank#} (instant) make you the life of the party, {#blank#}7{#/blank#} means that you needn't change your personality. Actually, there are {#blank#}8{#/blank#} (hide) strengths of being a quiet person as well as an active one. Make the most of your strengths, {#blank#}9{#/blank#} you can be successful regardless of which type you fall into and {#blank#}10{#/blank#} fast or slowly you walk.
