2 . Teenagers' fitness is now a major concern, to which physical exercise is very important. It reduces stress and improves fitness. Exercise makes your body strong, and helps you to keep the right body weight. Sports scientist Dr. Helen Lopez offers the following advice to teenagers: "First, you need to find out your present level of fitness.Then you can design a programme that will help you become healthier."

Dr. Lopez suggests that there are three levels of fitness that need a change of lifestyle. "Overweight" means that the person gets very little exercise and often has a serious weight problem."Inactive" means that the person does not join in many physical activities, but is not seriously overweight. "Active" refers to people who take part in sports and other physical activities, but are not at a high fitness level.

According to Dr. Lopez, overweight teenagers should keep active to keep healthy. "Ride a bike, play volleyball or basketball for a while, and go for a twenty- minute walk each day. All these will help to burn calories." Inactive teenagers should do similar activities, but add some bending and stretching exercises, such as push-ups and sit-ups, starting with twenty each day. "Inactive people can take a little more exercise than overweight people because their bodies are stronger," said Dr. Lopez. The same principle applies to active teenagers.

Dr. Lopez suggests one hour a week or more on running and other forms of intensive exercise (强化训练), together with fifteen minutes a day spent on stretching and bending activities. "These are really important in order to prevent injuries," Dr. Lopez said. Some weight-training and other body-strengthening exercises could also be planned in the programme in order to increase the person's strength.

3 . Before there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between.

    1    We dance from Florida to Alaska, from north to south and sea to sea. We dance at weddings, birthdays, office parties and just to fill the time.

“I adore dancing,” says Lester Bridges, the owner of a dance studio in Iowa. “I can’t imagine doing anything else with my life.” Bridges runs dance classes for all ages. “Teaching dance is wonderful.     2    It’s great to watch them. For many of them, it’s a way of meeting people and having a social life.”

    3    “I can tell you about one young couple,” says Bridges. “They’re learning to do traditional dances. They arrive at the class in low spirits and they leave with a smile.     4    ”

So, do we dance in order to make ourselves feel better, calmer, healthier? Andrea Hillier says, “Dance, like the pattern of a beating heart, is life. Even after all these years, I want to get better and better.    5     I find it hard to stop! Dancing reminds me I’m alive.”

D．My older students say it makes them feel young.

E．I keep practicing even when I’m extremely tired.

F．Dancing seems to change their feeling completely.

G．They stayed up all night long singing and dancing.
