Wantang Primary School,     1     (locate) in Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, came into the spotlight after all     2     (it) 536 students cleared the myopia (近视) test.    3     (surprising), no nearsighted student was found in the school.

A national myopia survey     4     (conduct) from September to December 2020, which found 52.7% of Chinese students had myopia in 2020, 2.5 percentage points     5     (high) than that in 2019.The rate was as high as 80.5%among high school students and 14.3% among 6-year-olds.

Against this situation,    6     Wantang Primary School has achieved is no less than a miracle.

Reports say students there follow     7     healthy routine with three hours of outdoor games every day, and at least 10.5 hours of sleep. They are not allowed to carry smartphones to school. The most effective of all these     8     (measure) is the three hours of outdoor games every day. Exposure to sun is known to decrease the severity of myopia, because natural light stimulates the retina (视网膜) and releases dopamine (多巴胺). As students adjust their eyes     9     different light patterns while playing outside, from very bright to less bright, it helps prevent myopia.

In contrast, when children spend a long time     10     (study) indoors, their eyes cannot get enough sunlight and therefore produce less dopamine, which leads to them getting myopia.

Other schools should let their students play outdoors more often.

You already know the fact that regular exercise is important for controlling weight and     1     (avoid)a variety of health conditions. But it can also improve your academic     2    (perform). And. if you’re a distance learning student, you may miss out on some of the opportunities for physical activity afforded to more traditional students who routinely walk around campus. But it’s well worth the effort     3     (put) the schedule exercise into practice.

The study, which     4    (publish) in the Journal of Medicine & Science, describes physical activity as     5     vigorous movement that produces sweat and heavy breathing. Mike McKenzie found that students who studied over three hours per day were 3. 5 times     6    (likely) to be exercisers. Over a decade ago, McKenzie     7     (say) researchers discovered a link     8     exercise and focus in children.

More recently, another study by Johnson reveals that even short ”microbursts“ of physical activity throughout the day can have positive effects. Jennifer tells that sitting for long periods of time,     9    college students tend to do, can have a negative health effect. In addition, the study found that five-minute bouts of walking every hour had a positive impact on mood, tiredness, and hunger at the end of a day. This may be     10    (particular)beneficial to students who also work a full-time job and study in the evening and nighttime hours.

Videos on the social networking platform Douyin—also known globally as TikTok—that show men and women with perfect body working out,     1     (be) common.

    2     (try) to stand out from the crowd among the large number of such videos can often be difficult, but a     3     (relative) new account, which has only been active since last year, has managed     4     (do) so easily.

The fitness instructor behind this account is not a young woman     5     a thin figure that would leave viewers green with envy (羡慕). The star here is 70-year-old Chen Jifang, a Shanghai resident (居民)with 3 million     6     ( like) on her Douyin videos. She was once even featured on a     7     (real) show on China Central Television.

According to her trainer,     8     helped to manage the Douyin account, Chen attracted more than 400,000 followers within just     9     few months.

“The main group that I want to encourage is people aged 30 to 50,” says Chen. “I think they will     10     (inspire) to work out in the gym after seeing that a granny like me can. The message I want to convey is that it is never too late to pursue good health.”
