    We always knew our daughter Kendall was going to be a performer of some sort. She entertained people in our small town by {#blank#}1{#/blank#} (put) on shows on our front porch when she was only three or four.

    When Kendall was five, we began to notice that she was blinking a lot and clearing her throat {#blank#}2{#/blank#}(frequent). We had her {#blank#}3{#/blank#} (test) for allergies(过敏), but the doctor said she wasn't allergic to anything at all. We took her to our local children's hospital, in {#blank#}4{#/blank#} she was diagnosed {#blank#}5{#/blank#} Tourette's Syndrome.

    We took her from doctor to doctor, but all they did was give her medicine that just made it {#blank#}6{#/blank#} (bad), so we decided to go the natural route and luckily she got better. When Kendall was sixteen, we thought she was out of danger. But at a birthday party, {#blank#}7{#/blank#} accident happened and she was badly hurt. Her biggest concern wasn't whether she would walk again, but whether she would be able to sing for American Idol.

    She trained hard and willed {#blank#}8{#/blank#} (her) to move again. At last Kendall walked into the stadium to sing for American Idol. And our {#blank#}9{#/blank#} (tear) turned into shouts when she {#blank#}10{#/blank#} (give) a golden ticket to Hollywood.

    On the first day of my first grade, I stood by the door with butterflies in my stomach. I {#blank#}1{#/blank#} (voice) my biggest concern to my mother. "How will I make friends?" She handed me advice. "Be yourself." For the past 20 years. I have lived by these words. Soon I will graduate and become part of the real world. Nervously {#blank#}2{#/blank#} (face) challenges. I know I will whisper to {#blank#}3{#/blank#} (I) the two simple words "Be yourself".

    China has once again proved its {#blank#}1{#/blank#} (able) to change the world with the "new four great inventions": high-speed railways, electronic payments, shared bicycles and online shopping. They're related to China's high-tech innovation (创新),{#blank#}2{#/blank#} has improved the quality of people's lives, according to a survey {#blank#}3{#/blank#}(make) by the Belt and Road Research Institute of Beijing Foreign Studies University.

    "My wallet is no longer in use. I can buy and eat whatever I want simply with a fingertip on my phone," said {#blank#}4{#/blank#}university student, adding that "even pancake sellers are using mobile payment".

    The bikes {#blank#}5{#/blank#}(them) are not new, but the operating model of bike-sharing {#blank#}6{#/blank#}(base) on satellite navigation system, mobile payment, big data and other high technologies.

    China has entered a new innovative era, thanks to the large amounts of capital China has invested in {#blank#}7{#/blank#}(encourage) innovation, said Bernhard Schwartlander, WHO Representative in China.

    It is increasingly clear that China is innovating and no longer copying Western ideas. This is especially true in mobile, where China is leading {#blank#}8{#/blank#}many ways such as…social messaging app WeChat, she said. This is partly {#blank#}9{#/blank#}China skipped over the PC era and went directly to mobile. China has a {#blank#}10{#/blank#}(large) mobile use than any other country in the world.
