    Many teenagers are short of exercise in their spare time now.
    All in all，teenagers need to do exercise in their spare time.The more exercise they do，the better it is for them.______

【考点】安全与健康．

【答案】Many students are short of exercise these days.On the one hand，they have too much homework to do after school.On the other hand，they probably have so many after-school classes such as playing the piano.So there is no time for them to do exercise.
Being short of exercise is harmful to students.They are growing quickly，so they need to do more exercise to keep healthy.Even though they are too busy with their schoolwork，they still need to play sports to make their bodies strong.I think they had better exercise in their daily life.First，they can take a walk after dinner on weekdays.After all，it's bad for them to do homework at once after dinner.Second，they can go swimming on weekends.Swimming is a very good sport and it doesn't need too much time.
All in all，students need to do exercise in their spare time.The more exercise they do，the better it is for them.
