    The GIF turned 30 this year,{#blank#}4{#/blank#} is even two years older than the World Wide Web itself. Ever since the GIF{#blank#}5{#/blank#} (create) in 1987, it has long been overlooked. It wasn't until the age of smartphones and social media{#blank#}6{#/blank#} it became part of our daily lives.

    The GIF does a {#blank#}7{#/blank#} (good) job of showing people's feeling than short text messages do. It is also a very small file format compared with regular videos, which helped it become popular among smartphone {#blank#}8{#/blank#} (use).

    Anna lost her arms in a car accident when she was a teenager. What was worse, she lost her parents at {#blank#}1{#/blank#}age of 20. Her elder sister, {#blank#}2{#/blank#} was ten years older than her, wanted to take care of her. However, Anna refused {#blank#}3{#/blank#} (live) with her sister, saying that she would take care of {#blank#}4{#/blank#}(she). She managed to enter college and {#blank#}5{#/blank#} (study) very hard. Four years later, she graduated and {#blank#}6{#/blank#} (give) a job. Once she wrote {#blank#}7{#/blank#} her diary, “I am quite lucky. Though I lost my arms, I still have my legs.” Anna chose to face her misfortune in a positive way. Instead of {#blank#}8{#/blank#} (feel) sad every day, she decided not to let it hold her back. She has taught us a good lesson. When something bad happens to us, we have two {#blank#}9{#/blank#} (choose). One is to complain, and the other is to face it {#blank#}10{#/blank#} (brave). If we choose to escape, it will always follow us wherever we go. If we decide to be strong, new hopes will come. So choose wisely.
