Being a parent of a teenager is not easy. If you have a teenager at your home, you usually feel difficult and tired. 

Parents must first understand the reasons before they start to solve the problems. There are too many reasons for problems between teenagers and parents, but there are some common reasons for parents and teenagers' problems.

Firstly, a teenager gets bad grades at school. The parents of the teenager with problems of getting the bad grades in school will be worried about the teenager's future. Secondly, a teenager is hanging out with a bad group. Thirdly, parents can't have a good talk with their teenagers.

In fact, parents can solve these problems. There are lots of parents who have the same problems as you. You can ask them for some advice. You can also ask the teenagers' teachers for help. Going to a family counsellor (顾问) is also a great idea. After all, family counsellors know some good ways to solve the problems between teenagers and their parents and they can be helpful. What's more, you'd better read some books about parenting in your free time. Though it is an old idea, it really works. Finally, do things together, such as going to a movie or playing games. You and your teenagers can find lots of common topics (话题) in these activities.

All in all, solving family problems might seem hard, but if everyone talks about his or her feelings, everything should work out in the end. There are many books about parent and teenager relationships and the books can help you improve your talks. Just try your best and everything will improve slowly. 

Since September, many schools have more PE classes from three times a week to five or even more. This is in response to(响应)China's new standard(标准)on PE classes. The standard asks schools to make sure that 10 to11 percent of all class time must be PE classes, third only to Chinese and math. 

The standard not only asks students to do easy exercise, but also asks schools to give students other popular sports to do. 

Ma Jiajun, 15, from Jilin, set a new world record for ""the most consecutive jump rope triples(连续三摇跳绳)"with 701 times. His teacher Chen Peng said that the school has always kept an eye on PE. With Ma as a role model now, students are more hard-working on not only jump rope but also other kinds of sports.

"At first tai chi was only needed during break time to show Chinese traditional culture, but students fell in love with it, " said Gao Yuxiang from a middle school of Shandong. Grade 8 students all need to do it, and there's a tai chi competition every year for Grade 8 students. "Different from ball games, tai chi can make me relaxed and help me get ready for the next class, "said Gao.

"I really enjoy hip-hop dance, "Ren Jianing, a high school student, said, "The class doesn't need any experience, so anyone can learn. "Every class they practice a part of the dance and in the next class put the parts together into a whole dance. "Our shirts are all wet after class even on the coldest days of winter, "said Ren.

On a school day, 60 students at Xishan Primary School in Shunde, Guangdong, are learning how to make corn soup and fried rice in an after-school cooking class. Working in groups of four or five, the little cooks take their responsibilities (责任) very seriously. Soon, they are showing off their own delicious dishes.

"Since last September, the school has set up after-school classes for students, with cooking classes being the most popular", said Xinhua. It comes after the "double reduction" policy (政策). The policy aims to ease the burdens (负担) of too much homework and off-campus tutoring (课外辅导) for primary and junior high school students.

The policy lists requirements in areas such as reducing the amount and difficulty of homework, as well as improving the quality (质量) of education and after-school services. For example, homework for junior high school students should take no longer than 90 minutes to finish. It gives students more free time for their hobbies and interests. Also, off-campus tutoring has been further regulated (管理) to reduce the burden on students.

"Our homework is clearly less than before," said 13-year-old Shen Yuzhe from Beijing. "We are not encouraged to buy workbooks any more. The exercises are mainly from the textbook." According to Shen, teachers have taught at a much slower pace, which gives students enough time to study.

In December, the Ministry of Education reported on the progress (进步) made through the policy so far. Almost all primary and middle schools now offer two-hour after-school services on weekdays. More than 90 percent of students can finish their written homework in the set time. About 92.7 percent of schools have opened after-school arts and sports classes. More than 80 percent of academic tutoring institutions (学科类校外培训机构) have closed down or turned to other fields of business.

"With homework done at school, my child and I can read books and listen to music together in the evening, or we can go out to play badminton or skip rope," said Lu Di, the parent of a fifth-grader in Qiqihar, Heilongjiang.
