Free time is a good chance for teenagers to have fun. What about free time with parents around? Some teenagers want free play without parents' supervision(监管) while parents and experts(专家) may think differently

Lin Tao, a middle school student, thinks teenagers should be free to play. "Last time I played with my parents around, I was nervous and just couldn't enjoy myself to the fullest, " Lin says. "And my friend Chen Xiaoxin has similar experiences. Once, he went out to play with his classmates. Everyone felt uncomfortable with his mother's supervision. "

Wang Min, a mother of a 14-year-old boy, thinks playtime needs supervision. She explains "People usually say I like to control my kid, but that's not true. I am just worried that he will get into trouble. Some guys may have a bad influence on him and some games like LARP(剧本杀) may mislead him. He might even get indulged in the stories and can't get back to real life. "

Mr. Ma, a doctor of social studies, says it's understandable for teenagers to wish for freedom. Free play helps them to be independent. Parents can give them more space. They don't have to supervise them all the time. However, teenagers should find out the exact details(细节) about the activities before playtime. Then they can communicate with their parents and decide together whether they can go out to play alone.

Jerry is a world—famous mountain climber. He has climbed many high mountains in the world. Starting in 2015, he and his friends spent two years on an adventure (探险) in South America, covering 7,800 miles. He was even named Adventure of the Year by a famous geography magazine in 2018.

Although Jerry had achieved great success, he didn't feel fulfilled. He asked himself, "Is it enough to climb the highest mountains? Am I doing something helpful? How can I turn my adventures into something that can help the world?"

Jerry learned that scientists need plans, rocks and water samples (样本) from the places far away to do research. But scientists can't get there themselves as such places are hard to reach—only the bravest adventurers can make it. Jerry thought himself could do something to help. He then came up with an idea. He set up a team of top adventures to collect samples for scientists. By studying the samples, scientists could know more about the earth and find ways to protect it.

Recently Jerry and his adventurer friends have discovered a special plant life of Mountain Qomolangma. The samples they brought back have helped scientists how plants live in extreme(极端的) condition.

For Jerry, this kind of adventure is most satisfying. "Such adventures had made us see life in a different way. Now, being the best climber isn't important for me. What matters is doing something helpful while climbing the mountains. There is still much more we can do." Jerry said to a newspaper.

Mrs. Luo is a teacher. She asked her students to hand in their homework through a QR code (二维码 ). "When students finish the homework, they keep it on We Chat. So I can check their homework everywhere using my computer or mobile phone," said Luo.

Most students like the new way and think it is interesting. "We are living in the formation age Many students like to work with computers, which makes laming more fun," said Tingting, a student of Luo's.

"The paper is not easy to keep, but the code is easy to keep and share," lug said. "It is worth trying to use new technology in education. Education itself is a kind of creation. I don't want my students to fall behind the times."

However, some parents are worried. They are afraid that their children will spend too much time on computers and little time communicating with teachers. But in fact, it is unnecessary. Students still need to    ▲   information in books and write it down when they do their homework, which doesn't take them too much time. As for teachers, it allows them to check the students' work at any time. And it is also an easy way to share homework with other students.
