1 . For better eyesight (视力), doctors advise limiting (限制) the hours of screen time and encourage having enough eye resting time.
However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia (近视). An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia. The research team found that there were less children who had myopia in Sydney than those in Singapore, even though they spent more time in front of computer and TV screens. The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore.
Indoor and outdoor sports both make the eyes pay attention to more distant (远处的) objects, which stops the eyes from changing original shape. But outdoor sports may be better than indoor sports for myopia. Because natural light is good for eye growth and vitamin (维他命) D from the sunlight might be useful to it. Many doctors suggest that every child get its first eye test when he/she is about two and half years old, and even if his/her sight seems good enough. It is necessary for myopic(近视的) children to wear glasses to stop headaches, trouble reading and so on. It is also important that schools invite doctors to test their students’ eyes.
If that is not possible, school teachers should at least encourage parents and children to have regular eye examination and wear glasses. And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors.

2 . Playing sports is a lot of fun. Getting hurt is not.
Wear protective equipment.
The equipment you wear depends on the sport you play. Helmets (头盔) are the most common protective equipment. They protect your head while you’re playing football, baseball, softball, and so on.
Warm up.
Know the rules of the games.
Traffic lights help prevent crashes between many cars that run on the road together. This works because drivers know the rules and follow them—at least most of the time.
This is a really important one. If you love sports, you may want to get back in the games, even after an injury. But playing when you’re hurt is a bad idea.
Now you know how to prevent sports injuries. If you follow these rules, you can stay safer while you are playing sports.
A.Don’t play when you’re injured. |
B.Don’t do too much exercise. |
C.It’s the same with sports. |
D.It can lead to an even worse injury. |
E.It’s not a good idea to just go to the field and start playing. |
F.You and the other players know what to expect from each other. |
G.Take these steps to prevent injuries so you can stay in the game. |
3 . Even though one out of three American children live within a mile of their schools, almost not half of those students often bike or walk to class, scientists report. Children who live in the South, in country areas, or who have college-educated parents, are among those least likely to bike or walk to school, which is reported in the American Journal of Preventive Medicine.
Sarah Martin and her workmates at the US Centers for Disease Control and Prevention (CDC) studied materials from more than 7,000 children between 9 and 15 years of age. They found that almost 35 percent of the children lived within one mile of their schools. Children between 11 and 13 years old were more likely to walk or bike than 9-year-olds. Children whose parents had a high school education were more likely to ride a bike or walk than children with college-educated parents.
“The majority of children are missing an opportunity to increase daily physical activity,” Martin said in a prepared statement. According to the CDC, nearly one in five (18.8 percent) children between 6 and 11 years old are overweight. Increased daily physical activity is one of the methods the CDC gives to help deal with the problem among children.
According to Martin, there are all kinds of reasons why children in city areas might be more likely to bike or walk to school. They pointed out the fact that if schools are in places where there are fewer safe sidewalks, the students will be less likely to ride or walk to school. The students should try to ride or walk to school as much as possible and parents are advised to pay great attention to their children’s health.
