Ⅰ.阅读理解

Healthy Habits,Healthy Body

Feel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you.

Then,consider this: you might be in a state of subhealth(亚健康).

Subhealth,also called the third state or gray state,is explained as a borderline state between health and disease.

According to the investigation by the National Health Organization,over 45 percent of subhealthy people are middle-aged or elderly.The percentage is even higher among people who work in management positions as well as students around exam weeks.

Symptoms(症状) include a lack of energy,depression (压抑),slow reactions,insomnia (失眠),agitation,and poor memory.Other symptoms include shortness of breath,sweating and aching in the waist and legs.

The key to preventing and recovering from subhealth,according to some medical experts, is to form good living habits,alternate work and 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, fruit and fish because they are rich in nutritional elements-vitamins and trace elements that are important to the body.

Nutrition(营养) experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化系统).They also say that a balanced diet is very helpful in avoiding subhealth.

[语篇导读] 本文介绍了亚健康的症状、原因及治疗的对策。 1.According to this passage,which of the following is RIGHT?

A.When you are in a state of subhealth,you should stay home and keep silent.

C.When you are in a state of subhealth,you should have yourself examined in foreign countries.

D.When you are in a state of subhealth,you should find out the reasons and relax yourself. 解析:细节理解题。根据全文及第五、六段可知处于亚健康状态不是待在家里、不是去看医生、也不是到国外去检查,而应该找到症状出现的原因、养成良好的生活习惯,故答案为D。

答案:D

2.It may be easy for middle-aged people to be in a state of subhealth because ________. A.they have used up their energy B.they have lost their living hopes C.they have more pressure in life and work D.they begin to get older
