Feeling tired lately? Has the doctor said he cannot find anything wrong with you? Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong. Then consider this, you might be in a state of sub health (亚健康).
Sub health, also called the third state or grey state, is explained as a border line state between health and disease. According to an investigation by the National Health Organization, over 45 percent of sub healthy people are middle-aged or elderly. The percentage is seven percent higher among people who work in management positions as well as students around exam time.
Symptoms include a lack of energy, depression, slow reactions, insomnia(失眠), agitation(焦虑), and poor memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.
The key to preventing and recovering from sub health, according to some medical experts, is to form good living habits, alternate work with rest, exercise regularly, and take part in open-air activities.
As for meals, people are advised to eat less salt and sugar. They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements——vitamins and trace elements——that are important to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy change in the digestive tract(消化道). They also say that a balanced diet is very helpful in avoiding sub health.

Physical fitness is the result of many factors: good medical and gentle care, proper nutrition, enough rest and relaxation, and sensible personal habits. But these are never enough. An essential factor is regular physical activity for a body to function well.
All of us know that ordinary movements like running, jumping, and bending are made possible by muscles. Muscles also do many other things. They suck air into your lungs, push food along your digestive tract（消化管）, and tighten your blood vessels to raise blood pressure when you need more pressure for an emergency. Your heart is a muscular pump（强健的泵或抽水机）.
When your muscles are not used, or not used enough, they do not develop and grow properly. They soon become weak, smaller in size and lose their ability to do the jobs they were meant to do.
Recent studies showed that the average high school student spend fifteen to thirty hours a week watching television and only two hours a week in organized play or exercise. That is one reason why one-third of the 200,000 pupils tested for the President's Council on Physical Fitness failed a simple test of strength. Some of the boys and girls could not raise themselves to a sitting position without using their hands!
Cars and buses, lifts, TV and push-button machines all tend to reduce physical activity. But our bodies still need exercise. Without it they soon become weak and unattractive.
1． In the article，muscles are said to do all of the following except _______ .
A．suck air B. run， jump and bend C. tighten blood vessels D. reduce pain
