    Early in the morning, at noon, or in the evening in big cities and in the countryside, all over the United States, you can see Americans running—men and women, young and old. People run1 — along the beaches of California, 2 Central Park in New York, down quiet streets in small towns or at the gym. Some people even run in 3 living rooms.

    Running wasn't so popular in the past. In the 1960s, runners were mostly athletes and healthy strong people. When people saw a runner, they used4, "Hey, what's the hurry for?" or they might say to 5 , "Is he crazy?" At that time, women almost never ran. If they did, they might be laughed at. But today all these have6. Men and women of all 7 enjoy running.

    Doctors say many of the health problems in the United States 8these bad habits: eating too much, smoking cigarettes, and taking 9 exercise. Doctors tell us, "Eat less, don't smoke, and exercise more." Running is good exercise10 it helps build strong hearts and lungs. It also helps most people lose weight.

    Exercising is a good way to keep fit. However, many people do not know how to exercise well. Here are some tips.

    First, you should warm up. It is important to warm up before you exercise. You need to stretch your legs, arms, back and neck before you do any difficult activities like running.

    Second, you should find good places to exercise. You do not need to spend a lot of money. You can run or do sports in a park or in your school gym. You don't need to buy exercise equipment for your home. Just get your body moving. 

    Third, don't work too hard. Choose a sport that you enjoy and then your exercise will be fun instead of work. Also, you only need to exercise a few times each week. If you exercise 30 minutes each time, you will stay healthy.

    Fourth, drink enough water. It is important to drink water when you exercise. Your body needs the water for energy and for keeping cool.

    Finally, you must be careful! If you hurt yourself while you are exercising, rest until you feel better. Exercising when you are hurt is bad for your health.

    Skin­diving is a new sport today. This sport takes you into a wonderful new world. It is like a visit to the moon. When you are under the water, it is easy for you to climb big rocks, because you are no longer heavy.

    Here, under the water, everything is blue and green. During the day, there is plenty of light. When fish swim nearby, you can catch them with your hands.

When you have tanks of oxygen on your back, you can stay in deep water for a long time. But you must be careful when you dive in deep water.

    To catch fish is one of the most interesting parts of this sport.

    What's more, there are more uses for skin­diving. You can clean ships without taking them out of water. You can get many things from the deep sea.

    Now you see that skin­diving is both useful and interesting.
