Having a teenager at home can be a real headache. Many teenagers smoke, wear strange hairstyle and even fight. Basically (基本上) , they are often taking risks.

Earlier studies have shown that teenagers are more likely to make irrational decisions than people from any other age group, including children and adults. Is it that teenagers are too young to tell right from wrong? Not really. So what’s the reason?

According to Laurence, a teacher from a US university, the reason is that teenagers care a lot about how their peers (同龄人) view them—that is “peer influence”.

As children enter their teenage years, they spend more time with their friends and classmates, and also they care more about what they think of them. This makes teenagers make decisions without thinking about the costs.

In a test, a group of teenagers were asked to play a video driving game. When they played with their friends watching around them, they took more chances and drove more carelessly because that would increase their possibility of winning. But when they played alone, they drove more safely.

Why do peers have such a big influence on teens’ behavior?

As Laurence sees it, a teenager’s brain is like a car with a good accelerator (油门) but a weak brake (刹车). The “accelerator” is fully developed by teenage years while the “brake” is still not fully developed. When teenagers are watched by their peers, they usually push hard on the accelerator. With their weak brake, it is likely that they are going to end up in an accident.

But the good news is that a violent (暴力的) teenager doesn’t necessarily become a violent adult. About two-thirds to three-quarters of violent youth grow out of it. “They get more self-controlled.”

Are you a gourmand(美食主义者)? Do you want to eat every delicious food in the world? Then do you watch the popular program? “A Bite of China(舌尖上的中国)” is a documentary on Chinese delicious food which has been broadcasted by Chinese central television. Is there any holiday that isn't celebrated with a special festival food? Here are several traditional Chinese foods:

Eggs hold a special meaning in many cultures, and China is no exception(例外). The Chinese believe eggs mean producing something new. After a baby is born, parents may hold a "red egg and ginger party," where they pass out eggs to announce the birth. In some areas of China the number of eggs represents the sex of the child, for example, an even number(1, 3, 5, ---) for a girl, and an odd number(2, 4, 6 ---) if a boy has been born.

Noodles are a symbol of longlife in Chinese culture. They are as much a part of a Chinese birthday celebration as a birthday cake with lit candles is in many countries. Since noodles represent long life, it is considered very unlucky to cut it off.

Although westerners sometimes may be very sorry to see fish lying on a plate, in China a whole fish is a symbol of richness. In fact, at a party it is traditional to serve the whole fish last, pointed toward the valued guest. Fish also has a special meaning because the Chinese word for fish, yu, sounds like the word for richness or plenty, and it is believed that eating fish will help your wishes come true in the year to come.

A very popular dish during the Dragon Boat Festival is Zongzi. This tasty dish is made of rice dumplings with meat, peanut or other delicious food in bamboo leaves. The tradition of Zongzi is meant to remind us of a great man, Qu Yuan.

The 50-minute program tries to bring something new by presenting more cultural elements(元素), such as eating habits and the quality of eating.
