1 . More than half of Chinese children and teenagers suffered from nearsightedness, according to a survey by the National Health Commission(NHC).

    1    . It covered 1.1 million students in 1,033 kindergartens and 3,810 primary and middle schools. It found that 81 percent of senior high school students were nearsighted. In junior high school and primary school, that rate was 71.6 percent and 36 percent respectively. In kindergarten, 14 percent of six-year-olds were nearsighted.     2    .

The common phenomenon of extreme myopia has also become alarming. According to the survey, the percentage of senior students in high schools who wear glasses stronger than six diopters went up to 21.9 percent.

According to Ma Jun, deputy head of the Beijing Ophthalmology Institute, the survey was the largest in recent years. This survey has provided a basis for taking targeted measures for control and prevention.

    3    . He said that insufficient outdoor exercise and sleep time, excessive homework and near-vision work, and improper use of electronic devices were the main causes.

Nearsightedness is not curable with current medical techniques.     4    . Experts suggest that children and teenagers should exercise outdoors for two hours a day, or 10 hours per week, and reduce their amount of near-vision work, as well as use of cell phones and computers.

    5    . The plan aims to keep the myopia rate among six-year-olds at around 3 percent by 2030, and the rate among junior and senior high school students below 60 percent and 70 percent respectively. Zhang said the commission will cooperate with education authorities to pressure local governments to carry out measures for the control and prevention of nearsightedness among students, and improve the monitoring of nearsightedness.

A．China made a plan last year to control the rise in nearsightedness among children and teenagers.

B．The high rate of nearsightedness has brought about many incredible consequences, according to NHC official ZhangYong.

C．The survey was organized by the Ministry of Education, Ministry of Finance and the NHC in 2018.

D．Thus, prevention work is particularly important.

E．Overall,53.6 percent(of these students) were nearsighted.

F．Several factors are associated with the high rate of nearsightedness, according to NHC official Zhang Yong.

G．Many scientists as well as educators are concerned about the increasing rate of nearsightedness.

2 . Sneezing is one of the many wonders of the human body and one of our protective reflexes (反射动作). When something stimulates the inside of our nose - such as dust or pollen - the tiny nerve endings inside our nose send a message to our brain that in turn sends out messages to many parts of our body to release the sneeze.

Sometimes you feel the urge to sneeze when you're in a meeting or during the quiet part of a play or concert. You might do your best to stifle the reflex so you don't sneeze. But it's better to interrupt your coworkers and seatmates than risk health consequences, say researchers.

According to a case described in the journal BMJ Case Reports, a 34 - year - old in Leicester in the U. K. ended up hurting his throat while trying to hold in a forceful sneeze. The man said he felt a “popping” sensation in his neck after pinching (捏) his nose and holding his mouth closed to stop a sneeze. The pressure didn't have anywhere to go, so it tore the soft tissue. The man had to be fed by a tube after the incident and eventually made a full recovery.

I know all sorts of sneezers, quiet ones and loud ones. Each person is different. As Dr. Mitchell Grayson, a professor at the Medical College of Wisconsin in Milwaukee, explains, “Some people have bouts (一阵) of sneezing. It's a neurologic reflex, and it depends on the person. Some people may have 10 to 20 sneezes in a row.” It usually depends on the level of irritation in your nose, because you'll keep sneezing until you get it out.

The saying that your eyes will pop out of your head if you sneeze with them open is false. Our eyes shutting tight when we sneeze is simply a reflex, much like our leg going up when our knee is tapped. It doesn't really have a good reason 一 it just happens.

3 . “The comic waist challenge”, in which netizens try to imitate a comic character's pose with their legs on a chair and the upper body dropping to the ground, almost bending the waist in half, has become the latest craze to hit China's social media.

The topic has obtained hundreds of millions views on Weibo with many net users posting photos of the challenging pose to show how sexy and flexible they are.

Meanwhile some netizens argue that it is just an expansive gesture of yoga pose. So some people consult the doctors if the gesture is very dangerous. Medical experts have warned net users of the seemingly harmless yoga pose, as it may lead to damage to one's vertebrae by causing muscle strain and increasing the risk of lumbar degenerative disease.

The new challenge follows a series of similar controversial Chinese body image trends including the A4 waist challenge (measuring women's waists against a piece of A4 paper which is 21 centimeters wide), the belly button challenge (reaching one's belly button from behind), and the coin collarbone (balancing coins on people's collarbones for as long as they can) which faced heavy criticism worldwide on social media.

Women in China have long associated being beautiful with being skinny, but a desire to be thin is often taken to the extreme, with harmful effects on health and self-esteem - a situation not unique to China.

Although the opinions of the issue vary, maybe the change of the attitudes towards it is just over the horizon. Rejecting body anxiety is more than just a slogan. Many workout-obsessed women are increasingly realizing that no matter how hard they try, they won't be supermodels, and acknowledging that figures can vary due to a number of factors. This is an important step on their path to self-acceptance. Being healthy and maintaining the spiritual well-being have become the new pursuits for many.
