　　Are you in shape?To find out, ask yourself some questions：Do I exercise regularly?Do I ever walk places instead of driving my car?Do I ever play sports for fun?Do I ever take the stairs instead of the elevator?If you answered no to any or all of the above questions, you are probably out of shape and need to start a fitness program．

　　Exercise is very important．It improves your strength and blood circulation(循環)．It gives you more energy．It can help you relax and sleep well, and it can help control your weight．In fact, the U．S．Surgeon General says that exercise can help prevent heart disease, diabetes, obesity, and osteoporosis(a disease that weakens the bones)．

　　The first step is to make a program．A good fitness program should be fun．It should involve(包含)both your arms and your legs, and it should help you to build endurance(the ability to do exercise for a long time)．To make a good program for yourself, first you should think about the types of activities you like to do, what you think you are able to do, and when you will have time to do it．A good exercise program will involve cardiovascular activities, such as running, biking, swimming, roller skating, playing soccer or tennis, or jumping rope．It will also involve weight-bearing exercise, such as weightlifting, and stretching activities．Also, daily, low-intensity activities such as walking, gardening, dancing, and climbing stairs are good for your physical health．

　　So what are you waiting for?Get off of the sofa and start exercising．Sign up for yoga, tai chi, or pilates．Join a gym or a running club, or just start walking a half an hour every day．Every little bit helps!

　　You will have a lot of reading to do in this grade this year．You can do more of it in less time if you learn to read rapidly．

　　Perhaps you have been told about some habits (習慣) which keep a person from reading fast and have been strongly asked to break those habits which you might have．

　　Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions．

　　(1) Do you move your lips (嘴唇) when reading silently?

　　(2) Do you point to words with your finger as you read?

　　(3)Do you move your head from side to side as you read?

　　(4)Do you read one word at a time?

　　If you answer“yes”to any of these questions,start at once to break the habit．If you move your tips，hold your fingers over them，or hold a piece of paper be-tween your lips while you are reading．Then if your lips move，your will know it and can stop them．

　　If you point to words，hold the two sides of your book，one side with your left hand，the other side with your right hand．Then you won't have a free finger to use in pointing while reading．If you move your head，place your chin (下巴) in one hand and hold your head still (靜止不動的)．
