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．

    Travel can teach kids more than a textbook. Travelling with kids is good {#blank#}1{#/blank#}them. They can find new interests. Travel makes information alive for kids, and makes it much more exciting than studying textbooks or{#blank#}2{#/blank#}experiments in the lab. While traveling, they learn{#blank#}3{#/blank#}to deal with new situations, and communicate with other people. They learn patience, because sometimes {#blank#}4{#/blank#}takes a long time to get to some exciting or interesting places.

    I've been traveling since I was seven years old. For me, to stop traveling would be like taking something {#blank#}5{#/blank#}from my soul(灵魂). I can't live without traveling and I wouldn't be who I am if I don't travel. Some people think it's {#blank#}6{#/blank#}to travel after having kids. But in my opinion, when people become parents, it doesn't mean they couldn't travel any more. My children have been traveling since they were three weeks old.

    Bringing a new life into the world comes with many responsibilities(责任)and I'd love to be a good mother. One of my duties is to educate my children. I'm{#blank#}7{#/blank#}thankful that my parents took me on family trips when I was young. I've learned that {#blank#}8{#/blank#}outside world is more colorful than the little one I was living in. Of course, I want to pass these travel {#blank#}9{#/blank#}on to my children.

    I value the memories I have traveling with my children. I'm sure they will always {#blank#}10{#/blank#}them in their lives.
