　　Unit 1 How often do you exercise? 文化背景知识介绍

　　1. In American, young people spend their free time in many different ways, according to their ages, interests, and environments. For many young people, watching television programs and using computers are popular activities. Many young people use computers to play games, look for interesting websites, listen to music, watch movies, send e-mail, and chat with their friends.

　　On the other hand, many young people enjoy outdoor activities. In a neighborhood, young people may play games with their neighbors including touch-football, basketball, tag, and hide-and-seek. Skateboarding, bicycling, and roller-blading may be popular. In winter, ice-skating, hockey, and skiing may be popular in areas where it snows. In middle school and high school, young people can join a sports team such as track and field, basketball, baseball, football, volleyball, swimming, and so on.

　　There are often clubs that young people can join, and these clubs usually meet after school. Such clubs might include the singing club in elementary school and band (orchestra) in middle school and high school. Other clubs include the drama club, mathematics club, foreign language club, debate club, student newspaper, and so on.

　　There are also community centers where young people can become involved in a variety of activities including sports, arts and crafts, and educational activities such as learning to play a musical instrument.

　　2. In order to stay healthy, you should do the following things.

　　Eat a balanced diet, which includes foods from the different food groups (grains, vegetables, fruit, meat, milk, sweets), and eat the most from the grains group and the least from the sweets group.

　　Exercise and drink lots of water and milk.

　　Get enough sleep. (Kids between 5 and 12 usually need 10 to 11 hours of sleep each night.)

　　Don't smoke or use drugs (including alcohol).

　　Take care of your teeth and gums.

　　Wear the proper clothing to stay warm (or cool), protect your skin from the sun, and avoid injury from activity.

　　See a doctor and a dentist on a regular basis.

　　3. To take care of your teeth, you should do the following:

　　Use toothpaste that contains fluoride.

　　Brush your teeth at least twice a day (after breakfast and before bedtime).

　　Brush all of your teeth (away from your gums) for about three minutes.

　　Use a toothbrush ever three mouths.

　　Be careful about what you eat and drink.
