      We all need to exercise. Doctors say it is good for us. It makes your heart and body strong. It also gives you more energy. And you will feel better about yourself. It's best to exercise twice a week. Twenty minutes each time is enough(足够).

      There are many ways to exercise. You can walk, run, play sports, or swim. Many people go to special (特殊) places to exercise.

      They are called “fitness centers”. These places have a lot of equipments (设备) . Some people buy equipment for their homes. But it is very expensive.

      Exercising can be fun. Friends can exercise together at a fitness center. Or, they can play sports together. How do you exercise?

      (A)You can make your body healthy by bathing. Do you know? It was popular hundreds of years ago. Modern bathing with medicine or hydropathy（水疗法）first became popular in America. For many years people thought if you always bathed, it was bad for health. They didn't think bathing every day just to keep clean was good idea. By the 18th century some doctors started to think that soap and water were good for health. They believed that it was good for people to be clean.    (B)    During the late 19th century, you would see a lot of families take a bath on Saturday night.

      In America bathing every day was slow to become popular. During the 18th and early 19th centuries, Americans hardly ever washed. In one American city, for example, a man could only take a bath every thirty days. That was a law（法律）.

      (C) Now it is a habit for people to bath every day. People know that bathing can make them clean and it is important for their health. Doctors know that dirty bodies can get ill easier. Today in America people bathe, and some even bathe once a day.
