1 . China has set new rules limiting the amount of time children can play online games. The rules limit children to just three hours of online game playing a week. That is one hour between 8 p. m. and 9 p. m. on Friday, Saturday and Sunday most weeks.

Li Zhanguo has two children aged 4 and 8. Even though they do not have smartphones, they enjoy playing online games. Like many other parents. Li is happy with new government rules. But experts say it is unclear if such policies can help prevent addiction to online games. Children might just get addicted to social media instead. In the end, experts say, parents should be the ones to set limits and support good practice.

There has been a growing concern in China about gaming addiction among children. Government reports in 2018 found that about one in ten Chinese children were addicted to the Internet. The new rules are part of an effort to prevent young people from spending too much time on unhealthy entertainment. That includes what officials call the “irrational fan culture”

Under the new rules, the responsibility for making sure children play only three hours a day as largely on Chinese gaming companies like Net Ease and Ten cent. Companies have set up real-name registration systems to prevent young users from going past game time limits. They have used facial recognition technology to check their identities. And they have also set up a program that permits people to report what is against the law. It is unclear what punishments gaming companies may face if they do not carry out the policies. And even if such policies are performed, it is also unclear whether they can prevent online addiction.

A specialist treating Internet addiction expects about 20 percent of children will find ways to break the rules by borrowing accounts of their older relatives and find a way around facial recognition. In his opinion, short-video alps such as Douyin and Kuaishou are also very popular in China. They are not under the same restrictions as games.

3 . A new study indicates that living in a city makes it harder for people to concentrate on some tasks. The research found that people living in rural areas can focus better than those in urban areas. The study is from Goldsmiths College, which is part of the University of London. Head researcher Dr Karina and her team made great contributions. They studied how two groups of people did the same “thinking tasks”. The team went to a remote (偏远的) part of Namibia, southwest Africa, to study the Himba tribe. Himba people live a very basic life in the desert. They are still doing traditional farming. The team also studied members of the same tribe who had moved to the nearest town. The Dr. said the tribe who lived in the desert did much better on the tests than those in the town. It’s really interesting and shocking.

Dr Karina said their research may lead to changes in the way companies operate. In the future, workers may move from cities to live and work in the countryside. She said there are too many things around us in the city that stop us from thinking about one thing for a long time. This means we do not work at our best. She asked, “What if, for example, companies realized certain tasks would be better carried out by employees based outside of the urban environment? There their concentration ability is better.” The past century has seen billions of people move from the countryside to big cities. In the future, the trend may not continue. If Dr.’s research is true, this century might see many of those people return to the great outdoors. Let’s wait to see what will happen.

4 .    

Cheating can happen in a lot of different ways.When people cheat,it’s not fair to other people，like the kids who studied for the test or who the true winners of a game were.

Many people like the action of cheating.In their opinion,it makes difficult things seem easy,like getting all the right answers on the test.But it doesn't solve the problem of not knowing the material and it won't help on the next test—unless the person cheats again.

Some people lose respect for cheaters and think less of them.The cheaters themselves may feel bad because they know they shouldn't get that good grade.And,if they get caught cheating,they will be in trouble at school，and maybe at home,too.

Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying.Other kids might feel like they can’t pass the test without cheating.Even when there seems to be a “good reason” for cheating,cheating isn’t a good idea.

If you were sick or upset about something the night before the day and couldn’t study,it would be better to talk with the teacher about this.And if you don’t have enough time to study for a test because of swim practice,you need to talk with your parents about how to balance swimming and school.A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together.Talking about these problems and working them out will feel better than cheating.

10 . Tests, after­school activities and problems at home can increase stress for students. But research now suggests that the main reason for the students’ rising anxiety levels is something else.

A psychology professor Jean Twenge said, “What a lot of teens told me is that using social media and their phones seems forced. This use of phones has led to a loss of sleep and face-to-face interactions.” Last year, in the journal Pediatrics three researchers wrote that too much social media use might contribute to the development of mental health problems in teenagers, such as loneliness, depressive symptoms and anxiety.

Researchers are still not sure whether phones cause student depression or depression causes phone use. Yet 70 percent of teens see anxiety and depression as major problems among their peers, according to a February Pew Research Center report.

Schools are starting to take steps to deal with the problem. Many public schools pay outside companies to watch students’ social media activity for signs of pain. Some schools have organized some events in which people do not use their electronic devices. Belfast Area High School in Maine had one such event in April. About 20 percent of students and school employees took part, demonstrating the influence that the technology has on their daily life.

Emily Mogavero, a 17­year­old student in New York, said, “I definitely feel stressed to keep up my information and stuff. It kind of worries me that I’m on my smart phone so long.” Mogavero said she sometimes puts her phone out of reach or powers it down so she doesn’t hear anything.

Some parents are not letting their children get smart phones until they grow up. A teacher, Erin Schifferli, says her 12­year­old daughter, Aeva, won’t get a phone until she is 16 years old. Deirdre Birmingham of Montclair signed on a campaign called “Wait Until Eighteen” because she didn’t think her video game­loving 10­year­old son was ready for a smart phone.
