The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics (有氧運動), strength building, and flexibility (柔韌) exercise. Make exercise a habit by arranging some time every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it’s OK to divide it into shorter exercise breaks throughout the day.
Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching (伸展) activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school — or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
Here are five simple ways to make an exercise lifestyle change:
小題1:The writer thinks many people probably misunderstand the word“activity” to be “_______”.  
A.physical activityB.body movement
C.sports hall exerciseD.outdoor exercise
小題2:When exercising, the most important fact is ________.
A.the time spent on exercise
B.the intensity of activity
C.the difficulty of exercise
D.the right balance of activity
小題3:The author advises dividing activity into shorter exercise breaks because ___.
A.exercising for a long time is bad for people’s health
B.it has the same effect as soccer practice
C.people usually haven’t much time to exercise
D.no one can spare lots of time to exercise
小題4:What’s the best title for this passage?
A.Regular exercise.B.School exercise.
C.Indoor exercise.D.Difficult exercise

There are many things you can do to improve your memory. Among them are many kinds of useful ways are well as taking special care of your health.
It is important that you make yourself excited to make your memory more active. You can do this by doing some new activities and by changing your daily habits. Learning a new skill helps your brain(大腦)to develop. When trying to remember something, you should pay special attention to the most important things about it .Do not allow other thoughts to enter your mind because this will reduce your chances of making right memories.
An excellent way to help memory is to connect information with pictures. Try to see the pictures in your mind. Taking notes and keeping a diary will also be helpful.
Healthy food and plenty of vitamins are necessary for your memory to work well. Drinking a lot of water also helps keep your memory. You must allow your brain to have enough sleep and rest. When you are asleep, your brain stores memory. Not enough sleep can cause problems with storing information. And being tired will also stop you from being able to think clearly and well.
In order to keep your mind on your work, you must be free from worry. Generally keeping fit and normal health checks are both important as well-not just for improving your memory.
