Facebook and Twitter are just two of my favorite things. These websites help me keep in touch with my friends and family, find out what     1     (interest) events are going on and see and share photographs within my social circle.

I began to wonder whether or not there could be a relationship between the hours I spent on the screen and the bad effects it had the next day at school.     6    (answer) my question, I made some research. I surveyed local middle and high school students. Eight hours is     7     recommended (建议的) amount of sleep for teenagers. From the responses, I found that those who slept for less than eight hours had about three hours of screen time per day,     8     kids who got more than eight hours of sleep had about two hours of screen time. The kids who slept less were more likely to suffer     9     stress, sleeplessness and anxiety. They performed poorly in tests and showed more mood     10     (problem).

Many netizens even joked that the 49-year-old was facing a contest with Li Jiaqi,     10     (know) as the King of livestreaming, because Li empties our wallet while Liu empties our body!

When people     1     (face) with health or nutrition questions, it is     2     (increasing) common to go online and diagnose themselves. But the Internet is full of conflicting health warnings with no regulation to get rid of the wrong advice, some of     3     is extremely dangerous! Also, search engines rank results by     4     (popular) rather than accuracy, so solid facts can be tricky to find. It is worth     5     (check) if the writer of an online piece is properly qualified as an expert. Anyone can call     6     (they) a “diet expert”, “nutritionist” and even a “doctor” — given it could refer to qualifications like a PhD. But remember, only officially     7     (recognize) practicing doctors as well as dietitians have degrees     8     giving medical     9     (suggest).

Then I focused     10     all the different kinds of candles and the special sales I could offer and convinced her that our candles were the best choice for gifts and home decorations. Finally she bought three candles.
