One day a dentist (牙医) was starting his morning work. {#blank#}1{#/blank#} (sudden) a man ran in. His face was red, {#blank#}2{#/blank#} he could only say “Quick! Quick!” The dentist thought he must be very {#blank#}3{#/blank#} (illness). His assistant (助手) helped to make the poor man sit in the chair. The dentist {#blank#}4{#/blank#} (give) the man some medicine {#blank#}5{#/blank#} (make) the man sleep. Then, he looked into the {#blank#}6{#/blank#} (man) mouth and pulled out all the bad {#blank#}7{#/blank#} (tooth). As soon {#blank#}8{#/blank#} the man woke up，he said in a low voice, “Quick, doctor, quick!”

    “It's all right now”, {#blank#}9{#/blank#} dentist told him, “It is over.”

    “You don't understand.” said the man. “I came to tell you that {#blank#}10{#/blank#} house is on fire."

    Are you busy a{#blank#}1{#/blank#} school? Can you s{#blank#}2{#/blank#} English? Then we n{#blank#}3{#/blank#} you to help w{#blank#}4{#/blank#} sports f{#blank#}5{#/blank#} English-s{#blank#}6{#/blank#} students. It is r{#blank#}7{#/blank#} and easy! Please c{#blank#}8{#/blank#} to the Students' sports c{#blank#}9{#/blank#}. C{#blank#}10{#/blank#} Mrs Miller at 6753846.

    I was very quiet and shy before I became {#blank#}1{#/blank#} member of the Teen Board. At my first meeting, I remember that the Teen Board members really {#blank#}2{#/blank#} (encourage) me to speak, as I was quiet {#blank#}3{#/blank#}the whole meeting. It was then that I realized my opinion did matter and people wanted to hear my opinion. That really improved my confidence and self-worth.

    {#blank#}4{#/blank#} (Be) a member of the Teen Board has helped me develop my voice around my friends, and that's {#blank#}5{#/blank#} (especial) true at school. One day, I saw a student being bullied (恐吓) by a big boy. I came to the boy and asked him {#blank#}6{#/blank#} (stop). There's no doubt (无疑) that the confidence I had gotten from the Teen Board helped me stand up.

    I joined the Teen Board {#blank#}7{#/blank#} I knew that the teens on the board would be a good influence. I also thought that many of them had probably faced similar school situations and knew that they would be a good support system.

    {#blank#}8{#/blank#} to the Teen Board, I become a more positive person. I no {#blank#}9{#/blank#}feel sorry for myself. Now, I'm a self-confident girl. And I want to {#blank#}10{#/blank#} my experience with others.

Tony: You know so much about {#blank#}1{#/blank#}. Do you like them?

Mary: Yeah. I {#blank#}2{#/blank#} about them from the encyclopaedia

Tony: What is the encyclopaedia?

Mary: It is a book having a lot of {#blank#}3{#/blank#} you want to know.

Tony: It is so{#blank#}4{#/blank#}. Where did you find it?

Mary: From our school library. There are different encyclopaedias. 

Tony: Can I {#blank#}5{#/blank#} what I like?

Mary: Of course.

    If you take the subway in Beijing，you may see there's nobody in the driver's seat．But don't be afraid—it just means you are on the new driverless line．{#blank#}1{#/blank#}September 2017，a driverless subway line{#blank#}2{#/blank#}(name)the Yanfang Line started to try running in Beijing．The line was open to passengers at {#blank#}3{#/blank#}end of 2017．The trains on the new line are the Chinese{#blank#}4{#/blank#}(one)domestically(国内地)made driverless subway cars．The line {#blank#}5{#/blank#}(build)between Beijing's Yanshan and Fangshan areas with 960 seats and a top speed of 80 {#blank#}6{#/blank#}(kilometer)per hour. The trains are{#blank#}7{#/blank#}(complete)self-driven．The general designer says the driverless trains actually run in a{#blank#}8{#/blank#}(safe)way than regular subway trains．And of course，the "drivers" of the new trains can't become ill{#blank#}9{#/blank#}tired．So far, twelve cities in China{#blank#}10{#/blank#}(begin)to build such driverless subway lines．
