The Internet {#blank#}1{#/blank#}(become) part of young people's life already. A report shows that 38% of students often use the Internet . Most of them get {#blank#}2{#/blank#} (use) information on the Internet {#blank#}3{#/blank#}use the Internet to help their studies. But many students don't use it {#blank#}4{#/blank#}a good way. Some play games too much, some visit websites that{#blank#}5{#/blank#}shouldn't look at. So bad things may happen{#blank#}6{#/blank#}students spend too much time on the Internet.

    {#blank#}7{#/blank#} is important for students to use the Internet properly. Now we have a textbook,{#blank#}8{#/blank#}uses many examples to teach students some good ways to use the Internet. It gives useful {#blank#}9{#/blank#} (advise).

    Some students also make friends on the Internet.  But  if you want to have  a face-to-face {#blank#}10{#/blank#} (meet) with your online friends, let your parents know and meet in a proper place.

    Have you ever asked {#blank#}1{#/blank#}(you) why children go to school? You will probably say that they go to learn languages, arithmetic, history, science and some other {#blank#}2{#/blank#}(subject). That is quite accurate. But why do they learn these things?

    We send our children to school {#blank#}3{#/blank#}(prepare) them for the time when they will be big and will have to work for themselves. Nearly everything they study at school has some {#blank#}4{#/blank#}(practice) use in their life. But is that the only reason for {#blank#}5{#/blank#}they go to school?

    There is more in education than just {#blank#}6{#/blank#}(learn) factors. We go to school to learn how to learn, so that when we have left school, we can continue to learn. A man who really {#blank#}7{#/blank#}(know) how to learn will always be successful, because when he has to do something new, he will not only be able to do it well himself, {#blank#}8{#/blank#}be able to teach others how to do it in the best way. The uneducated person, on the other hand， is either unable to do something new, or just does it {#blank#}9{#/blank#}(bad). The purpose of schools, therefore is not to teach languages， arithmetic, history science, etc. , but to teach pupils {#blank#}10{#/blank#}way to learn.

    When I was in the middle school, I founded a student club{#blank#}1{#/blank#} (name) "green planet" inspired by Chai Jing's documentary Under the Dome. At first people knew this club. As a result, we had only 15 members. And I {#blank#}2{#/blank#} (laugh) at for being crazy. However, I didn't lose heart and I insisted. Every day, we club y members broadcast weather reports and PM 2.5 levels. We then published articles and pictures of the serious {#blank#}3{#/blank#} (pollute) of the city on the school website. Meanwhile, my club also shares suggestions {#blank#}4{#/blank#} how to live a low carbon life on the school board, for example: take public transportation or car pool to school; do {#blank#}5{#/blank#} (little) shopping and so on.

    {#blank#}6{#/blank#} time went by, more are what students showed great interest in our club. And luckily, I persuaded my headmaster to join us. After what seemed ages of waiting, the club was finally accepted by the majority of students in my school. An increasing number of students supported {#blank#}7{#/blank#} (ours).

    Since then, we're worked together {#blank#}8{#/blank#} (promote) our club. And up to now, 85% of the students {#blank#}9{#/blank#} (join) us and enjoyed the simple but eco-friendly life.

Such is Joy, {#blank#}10{#/blank#} responsible and persistent girl.

    Out of the 20 little things you've always wondered about, one of them {#blank#}1{#/blank#} (probable) has to do with the small {#blank#}2{#/blank#} (five) pocket on your jeans. By now, you might have given up on trying to use it since it's too small to fit anything you actually need. But why is it there in the first place? Well, today, it doesn't really serve {#blank#}3{#/blank#} purpose, but it used to in the late 1800s.

    Actually the small pocket is called a watch pocket because it was originally intended as a safe place for men to store their pocket {#blank#}4{#/blank#} (watch). It {#blank#}5{#/blank#} (date) back to Levis first ever pair of jeans, which hit the market in 1879.

    The Levi Strauss blog also pointed {#blank#}6{#/blank#} that originally, there were only four pockets on a pair of blue jeans, the watch pocket {#blank#}7{#/blank#} (include). "The first blue jeans had four pockets—only one in back and, in the front, two plus the small, watch pocket," the blog stated.

    So next time you find {#blank#}8{#/blank#} (you) standing casually with your thumb hooked in that small pocket, know that it originally {#blank#}9{#/blank#} (use) to store a pocket watch. And now that we've got to know the tiny jean pocket, find out {#blank#}10{#/blank#} blue is the most common color.
