3 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.

Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.

According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.

9 . Apps (short for applications) are becoming increasingly popular nowadays, and for good reason. They can help you out in just about every area of your life, whether it's keeping fit, communicating with friends, or even learning a language.    1    Here's what you should think about before downloading an app for language learning.

·Learn from diverse sources(not just apps)

Any seasoned language learner will tell you that the beauty of mastering a foreign language is the world which it opens up to you. This is a world of diverse sources(来源) of information, from newspapers and books to TV, radio, music and even real people. Would you limit yourself to one medium in your native language?    2

·Make it social

    4    I mean social for real. I owe the speed of progress I made in Italian to the support from Jim, my partner in study time. Find a friend to accompany you. Take an evening class. Borrow a book. Buy a book. Book a week away and attend a language school. Just don't forget your phone!

If I may speak sincerely, the combination of app, language school, Jim, evenings out, and a choice book or two proved extremely effective.    5
