According to a recent survey, violence did {#blank#}1{#/blank#}(existence) in schools. Students showed their fear and parents and teachers also expressed their great concern about it. {#blank#}2{#/blank#} (obvious), it's time for the whole society to pay more attention to the mental health of adolescents (青少年).

    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 to prevent violence from {#blank#}5{#/blank#}(happen) at school, for more and more students would drop out of school {#blank#}6{#/blank#}their personal safety could not be ensured. In fact, violence can {#blank#}7{#/blank#}(learn). Children learn violent behavior from adults or from {#blank#}8{#/blank#}they see on television or on the Internet.

    If I meet with school violence, I will not answer violence {#blank#}9{#/blank#}violence, for it will result in more 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 {#blank#}10{#/blank#}behave himself and keep away from violence.

In China, a site that amazed me was one {#blank#}1{#/blank#} (provide) by nature—the Hukou Waterfall on the Yellow River, the mother river of the country.

    The Yellow River was a main source of transportation in the past. Many ports and bridges were built and destroyed by the river's strong current(水流), and it was {#blank#}2{#/blank#} (challenge) for the locals back then to build a bridge {#blank#}3{#/blank#} was strong enough to withstand(承受) the current of the Yellow River.

    About 1,500 years ago, the locals of Puzhou, which is now Yongji,{#blank#}4{#/blank#} (make) several iron oxen anchors, each {#blank#}5{#/blank#} (weigh) more than seventy metric tons to hold a floating bridge across the Yellow River. It was amazing to see these{#blank#}6{#/blank#} person and I was astonished by the {#blank#}7{#/blank#} (wise) and workmanship of people back then.

    The hotels that {#blank#}8{#/blank#} (arrange) for us to stay in were among the best in each city we visited, which sums up {#blank#}9{#/blank#} China was shown to me, with sights both beautiful and amazing {#blank#}10{#/blank#} kind and helpful people.

    Beijing was once a city of bikes, known as the Bicycle Kingdom{#blank#}1{#/blank#} cars were reserved for official business and the politically powerful. However, decades of economic{#blank#}2{#/blank#} (grow) led to a huge flowing of cars in the city. Owning one became not just a marker of reaching the middle class but also a requirement for marriage. As the economy developed, autos pushed bikes off the roads{#blank#}3{#/blank#} (create) heavy pollution and miserable traffic.

    {#blank#}4{#/blank#}(fortunate), now Beijing may he returning to its roots. Thanks to about 20 technology companies, brightly colored shared bikes {#blank#}5{#/blank#}(flood) into Beijing in the last two years. Many local residents welcome the shared bikes{#blank#}6{#/blank#}the flexibility and freedom they offer. They pick up the bikes and then ride and drop{#blank#}7{#/blank#} off anywhere they like, locking the back wheel, with no need to find a fixed place.

    Analyses in China say it is three factors that contribute to bikes {#blank#}8{#/blank#}(increase) rapidly: a lot of cash looking for a home, a good idea and government support. “As the city s population grew, traffic jams got {#blank#}9{#/blank#} (bad).” Cai, the Ofo spokeswoman, said, “Shared bikes could solve the 'last mile' problem in {#blank#}10{#/blank#} environmentally friendly way.”

    I wonder if it is because I haven't been able to be outdoors for so long {#blank#}1{#/blank#}I have grown so crazy about everything to do with nature. I can well remember that there was a time{#blank#}2{#/blank#}a deep blue sky, the song of the birds, moonlight and flowers could never have {#blank#}3{#/blank#}(keep) me spellbound. That has changed since I came here. For example, one evening when it was so warm, I stayed {#blank#}4{#/blank#} (wake) on purpose until half past eleven in order to have a good look at the moon by myself. But as the moon gave far too much light, I didn't dare open{#blank#}5{#/blank#}window. Another time five {#blank#}6{#/blank#}(month) ago, I happened {#blank#}7{#/blank#}be upstairs until the window had to {#blank#}8{#/blank#} (shut). The dark, rainy evening, the wind, the thundering clouds held me {#blank#}9{#/blank#}(entire) in its power; it was the first time in a year and a half that I{#blank#}10{#/blank#}(see) the night face to face...

    Back in 1995, Jack Ma made his first trip to the US and used the Internet for the first time. After searching for “beer”, he saw that no results came up related {#blank#}1{#/blank#}China. When he then searched for “China” and still saw no results, he decided {#blank#}2{#/blank#} (set) up a Chinese website—the seed for Alibaba was sown.

    Ma {#blank#}3{#/blank#}(simple) wanted his company to have a {#blank#}4{#/blank#}(globe) and interesting name, and realized Alibaba was a story {#blank#}5{#/blank#}(know) across the world.

    The company{#blank#}6{#/blank#}(found) in 1999 and {#blank#}7{#/blank#} then has grown from 15 employees to over 30,000. Alibaba has directly and indirectly created 40 million jobs for China.

    Ma hopes to keep expanding Alibaba outside of China and is aiming for 2 billion {#blank#}8{#/blank#}(consume) and 10 million small businesses to use {#blank#}9{#/blank#}company outside of China.

    Ma became the richest man in China, when  the company he founded floated on the stock market last year with a value of around ＄140 billion—the {#blank#}10{#/blank#} (large) public offering in history.
