Last year, I had a chance to be {#blank#}1{#/blank#} exchange student. I went to the USA. It was the  {#blank#}2{#/blank#} (one) time for me to be there. I was {#blank#}3{#/blank#} (excite), because I had never gone abroad. When I arrived in America, I stayed with a host family. At first, I was {#blank#}4{#/blank#} nervous that I could hardly speak a word. But my host parents were very kind to me and helped me to be relaxed. Gradually, I managed {#blank#}5{#/blank#} (understand) them and my friends. Soon I got used to {#blank#}6{#/blank#} (live) in the USA. Now I can speak English {#blank#}7{#/blank#} (good) than before. Sometimes I still share my ideas {#blank#}8{#/blank#} my friends in America. I really enjoy my experience as an exchange student. It's exciting to 1ive in a country with {#blank#}9{#/blank#} (difference) culture. I hope that I will have more {#blank#}10{#/blank#} (chance) to go abroad.

Dear Dr. Know,

    How are you? Let me tell you something about my life now. I go to school {#blank#}1{#/blank#}subway, because my school is {#blank#}2{#/blank#} from my home. It {#blank#}3{#/blank#}（take） 30 minutes. {#blank#}4{#/blank#}school, there are so many {#blank#}5{#/blank#}（rule）: I  {#blank#}6{#/blank#}（can） run in the hallways. I can't {#blank#}7{#/blank#} noisy in class. I have{#blank#}8{#/blank#}（clean） the classroom every day. My teacher{#blank#}9{#/blank#}（say） I should follow all of{#blank#}10{#/blank#}（it）.

    I believe there are many things that we can do to make life in our town a lot better for teenagers.

    First of all, I think more bike lanes should {#blank#}1{#/blank#} (build). A lot of teenagers in my town bike everywhere, {#blank#}2{#/blank#} it's very dangerous because there is a lot of traffic. If there are more bike lanes in the future, it will be much {#blank#}3{#/blank#} (safe) for us.

    {#blank#}4{#/blank#} (two), I believe that we need more places for teenagers to go to. {#blank#}5{#/blank#} my opinion, teenagers won't cause problems in the street if there are more places for us to go to. So we need more {#blank#}6{#/blank#} (club) and other places where we can meet.

    Thirdly, teenagers here need more sports facilities. There {#blank#}7{#/blank#} (be) places to play ball games so far like tennis and basketball, but what about other sports, {#blank#}8{#/blank#} skating and rollerblading?

    Finally, I'm sure we'll make the town better {#blank#}9{#/blank#} we don't drop litter. If we all do something {#blank#}10{#/blank#} (help) now, our town will be much better for everyone in the future.
