Nearly forty percent of China's young people born after 1990 have turned off notifications（通知）from social media apps due {#blank#}1{#/blank#}sensing the negative effects of social media, according to the {#blank#}2{#/blank#}(recent) released Kantar China Social Media Impact Report, Beijing Evening News reported.

    The report shows that all kinds of social media, especially WeChat, {#blank#}3{#/blank#}(become) more and more popular in the past years among people over the age of 40, {#blank#}4{#/blank#} the WeChat use of the “post-90s” generation has slightly decreased, from 94.1 percent to 86.6 percent.

    Most of those people {#blank#}5{#/blank#}(interview) for the report mentioned that positive effects of social media include socializing with {#blank#}6{#/blank#}(acquaintance) and taking in more information. However, respondents also noted that social media has caused them to read fewer books, suffer from {#blank#}7{#/blank#}(bad) eyesight, sleep less and have less privacy, among other concerns.

    As {#blank#}8{#/blank#} result, 39 percent of the “post-90s”generation attempts {#blank#}9{#/blank#}(avoid) the negative effects of mobile phone use. In the first place, they turn off app notifications when necessary. Moreover, they intentionally limit the {#blank#}10{#/blank#}(frequent) of social media interactions and stay away from social media entirely in certain situations.

    How would you feel if you woke up and found your entire computers—including your photos, your recent documents—no longer{#blank#}1{#/blank#}(access)? What if you found out that they had been wiped from your computer, {#blank#}2{#/blank#}(leave) you with nothing but heartache?

I'm not talking about an external hard drive. I'm talking about an online backup solution that runs{#blank#}10{#/blank#} (quiet) in the background on your computer. If you have one installed (安装)，when your computer crashes, you'll be just one click away from bringing your files back to life.

When I brought her home with delight, I {#blank#}3{#/blank#}(tell) we could not have that dog in the house. My father told me we could take care of her{#blank#}4{#/blank#}we found another home for her. My father did all he could to avoid {#blank#}5{#/blank#}(stay) with the dog, giving her no attention. Occasionally, he urged me to find the new owner{#blank#}6{#/blank#}the dog. One day, when my mother and I came home from the grocery store, my mom stopped me at the front window.

Comets are among the most beautiful and interesting {#blank#}1{#/blank#}(sight) in the universe. For centuries, people {#blank#}2{#/blank#}(show) great interest in studying them. In 1682, Edmund Halley, an astronomer, noticed a comet that was especially bright and large. Based on his calculations, Halley predicted that this bright comet would return in 1758 or 1759—this was about 75 years {#blank#}3{#/blank#} he first saw the comet. The comet really returned on time and it was named "Halley's Comet" in honor of Edmund Halley.
