[填空题]Physical fitness is the result of many factors—good medical care, proper nutrition, adequate rest and relaxation, and sensible personal habit. But these are never enough. An essential factor is regularly physical activity-exercise for a body that needs it to function well.
All of us know that ordinary movements—things as running, jumping, and bending— made possible by muscles. Muscles also do many other things.

To find out what the weather is going to be, most people go straight to the radio, television or newspaper to get an expert weather forecast. But if you know what to look for, you can use your own senses to make weather predictions.
There are many signs which can help yon. For example, in fair weather the air pressure is generally high. Tile air is still and often full of dust. Faraway objects may look hazy. But when a storm is brewing, the pressure drops and you are often able to see things more clearly. Sailors took note of this long ago and came up with a saying "The farther the sight, tile nearer the rain. ’
Your sense of smell can also help you detect weather changes. Just before it rains, odors become stronger. This is because odors are repressed in a fair, high-pressure center. When a bad weather low moves in, air pressure lessens and odors are released.
