1 . 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.

Last Friday afternoon, we had basketball match against Class Three. At the beginning we both tried to show each to be the best player. We just ran around and didn't pass down the ball to others. Soon we fall behind. During the break, our headmaster Mr. Li patient advised us to working together as a team. We followed her advice. In the end we won the game but each of us felt happy.

Through this game, I realize deeply that in a team, we can't achieve success no matter what excellent each one is. The key to success are teamwork.

4 . Sports can help us a lot. Taking exercises can make us strong. In collective sports like basketball, volleyball or football, we will learn the importance of cooperation. And sports can also help us relax after work or study.

However, as the saying goes, “there are two sides of everything.” Sometimes we may hurt other players or ourselves if we are not careful enough when participating in sports activities. What’s more, too much or hard practice can be bad for our health.

Sports can make us healthy both physically and psychologically. It is also a good way for people to know each other and can improve friendship between people. So long as we are careful enough, sports can do us nothing but good.

I became interesting in playing football because a small accident. At that time, I was in primary school. One afternoon which I was walking by the school playground, suddenly, a football fell just in the front of me but almost hit me. I stopped the ball and kicked it hardly back to the playground. To everyone’s surprising, the ball went into the net. All the football player cheered loudly, say that I had a talent for football. I was persuaded to join them. From now on, I started to play football with classmates after school. Now, I am a member of our school football team.

Mountain climbing has appealed    1    many people. With more and more mountain climbing    2    (sight) developed, people are getting more chances to experience this exciting sport.

Those who aren’t brave enough to climb a mountain but still want to get a similar experience can go for man-made rock climbing wall. While mountain climbing is more difficult and dangerous and needs    3    (great) focus, the man-made rock climbing wall is less dangerous as the person just needs to climb a cliff(悬崖)    4    is not so high as a mountain.

Climbing man-made rock wall doesn’t need much skill and can    5    (do) with the help of a coach even if you don’t have any knowledge about the sport. However, those    6    (plan) to go for mountain climbing must have information about how this sport is carried out, though they needn’t learn the knowledge of mountain climbing    7    (thorough).

It is also important    8    (make) sure that you are fit to take part in this sport.    9    is suggested that you speak to someone with the first-hand experience of mountain climbing before planning to take up the sport.

I have tried climbing man-made rock wall with incredible    10    (brave) and the experience is very good. I would also like to try mountain climbing and I need to get enough courage for it first.

9 . 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.”

10 . When I was in my fourth year of teaching，I was also（and am still）a high school track and field coach（田径教练）. One year，I had a student，John，who entered my class when he was a junior. John changed to our school from Greece，and seemed to be interested in sports，so I encouraged him to join our track team. I explained to him that even though he had never taken part in it before，I did believe that he could do well in any event，and that I would be willing to coach him in whichever ones interested him. He accepted the offer，and began to work hard at every practice.

About a month later，I had found out from other sources that John was a first-class tennis player，winning various junior awards in his home country. I went to him asking，“John，I really appreciate that you came out for the track team，but why didn’t you play tennis instead？It seems that would interest you a lot more，since you’re so good at it.”John answered，“Well，I like tennis，but you told me that you believed in me，and that you thought I could do well in track，so I wanted to try it for that reason.”

From then on，I often remember my student’s reply. I told it to a friend and she suggested I write it down to share somewhere with more teachers. No matter how critical（挑剔的）students can be of themselves，I’ve found that a simple“I trust that you can do it！”can go a long way！
