【推荐2】Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle.

Keep a scientific diet. Keep in mind that sugar can be removed from our diet completely. Over intake of sugar is one of the main reasons for getting fat. Over intake of protein (蛋白质) or fat and low intake of fiber (纤维) can also lead to getting fat. We only need a few grams of protein every day to keep our body in order. Like rain to crops, not the more the better.

Be always in a good mood. There is a relationship between the mood and health. A good mood keeps you in high spirits. Thanks to the Internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains (廉价品) , enjoy music and movies and chat with good friends. Just keep happy.

Enough sleep. Two studies show the reasons why teens and adults don’t have enough sleep. With teens, a major reason is mobile phone use; with adults, it’s work. Meanwhile, a third study of young children shows that lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover from tiredness and the hurt caused by hard work in the daytime.

Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of the modern life, you don’t have time to do exercise every day, but at least three times a week and 45 minutes each time.

【推荐3】Technology is everywhere. Almost all of us carry some piece of technology with us every time. It’s true to say that technology makes our lives easier. However, scientists are saying that we need to give ourselves a break-otherwise we put ourselves at risk of developing hundreds of health problems. With all this free time, why not put it to good use and do something without technology?

To start with, you could learn a new skill. There are hundreds of possibilities: crafts(工艺), cooking, learning a musical instrument or a new sport. Maybe you’ve always wanted to learn to cook for your family, but haven’t had time? Perhaps you feel like learning how to knit(编织), so you can have a new sweater for the autumn? You could use your free time to learn something new—and perhaps it will lead to an exciting chance in the future.

If you just want to relax, why not go to a beach? Take along your favorite book and relax on the sand, or go for a walk along the coastline. If you don’t live near a beach, you could go to your local park. Why not take along a picnic, or try and discover some of the local wildlife?

Little things, like challenging yourself to complete a crossword or a Sudoku, are a great place to start. You could even follow the latest fashion: adult coloring books! Coloring is amazing, and it can be a nice way to escape from the pressure of modern life!

Whatever you choose to do with your summer, try something new! You might surprise yourself and find a hidden talent within you; you might make new friends along the way. Next time you find yourself aimlessly switching channels, have a think at what else you could spend your time doing.

【推荐1】Children are starting on digital devices at ever younger ages, and opinions on the effects of children's digital-media habits are deeply polarised.(两极分化的).

Jean Twenge, a psychology professor, thinks excessive use of the internet and social media makes children lonely and depressed and poses serious risks to their physical and particularly their mental health, sometimes to the point of driving them to suicide.

However, Daniel Kardefelt-Winther of the Innocenti research office of Unicef examined various evidence and found less cause for alarm than is often suggested.Most of the studies he examined seem to show that the technology helps children stay in touch with their friends and make new ones.

The relationship between the use of digital technology and children's mental health, broadly speaking, appears to be u-shaped.Researchers have found that moderate use is beneficial, whereas either no use at all or extreme use could be harmful.

What worries some experts more is that screens are becoming part of the middle-class armoury( 武器 ) for perpetuating( 巩固 ) social advantage.Children from well-off homes are enrolled in private classes to learn skills like "How to be a YouTuber", which poorer parents cannot afford.

【推荐3】China Youth says that more and more girl students have entered colleges to study in the recent few years. As we know, once the number of boys was larger than that of girls and boys did much better than girls in our country for a long time. Now, things have changed a lot.

In recent years, the proportion (比例) of girl students is growing fast. In 1998, about 39.7% of college students were girls. In 2000, it was 41.07% and in 2001, the number was 42.14%.

There are several reasons for this.

Firstly, there is little difference between boys and girls in their intelligence (智力). That’s to say, girls are as clever as boys. And boys have more interests than girls, so they may not always do well in their study.

Secondly, girls are more careful than boys. They work harder at school and they do better in all exams.

Another reason is that with the development of society, people pay more and more attention to girls’ education.
