Feel tired lately? Has a doctor said he can’t find anything wrong with you? Perhaps he has 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 sub-health（亚健康）. Sub-health, also called the third state or gray state, is explained as a borderline（界限）state between health and disease.
According to the survey by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week.
Symptoms include a lack of energy, depression, slow reactions, insomnia, anger, and poor memory. Other symptoms include shortness of breath, sweating and aching in the wai
st and legs.
The key to preventing and recovering from sub-health, 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, fruits, fish because they are rich in nutritional elements -- vitamins and other 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 changes in the digestive tract（消化道）. They also say that a balanced diet is very helpful in avoiding sub-hea
lth.

| A．When you are in a state of sub-health, you should stay at home and keep silent. |
| B．When you are in a state of sub-health, you should go to see a doctor and buy some medicine. |
| C．When you are in a state of sub-health, you should have yourself examined in foreign countries. |

We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it’s hard not to wonder if the disease that comes from foreign animals is homing in on human beings. “Most of the infections (感染) we think of as human infections started in other animals, ” says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University.
It’s not just that we’re going to where the animals are, we’re also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen’s pets, and she now thinks that keeping foreign pets is a bad idea. “I don’t think it’s fair to have them as pets when we have such a limited knowledge of them,” says Isaksen.
“Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,” says Peter Schantz. Monkey-pox may be thewake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But some strains (变异体) may become harmful. Monkey-pox doesn’t look a major infectious disease. But it is not impossible to pass the disease from person to person.We learn from Paragraph 1 that the pet sold at the shop may ________.
| A．come from Columbia |
| B．enjoy being with children |
| C．prevent us from being infected |
| D．suffer from monkey-pox |
Why did Isaksen advise people not to have foreign pets?
| A．They attack human beings. |
| B．We need to study native animals. |
| C．They can’t live out of the rain forest. |
| D．We do not know much about them yet. |
What does the phrase “the wake-up call ” in Paragraph 3 most probably mean?
| A．a new disease |
| B．a clear warning |
| C．a dangerous call |
| D．a morning call |
The text suggests that in the future we_____.
| A．may have to fight against more new diseases |
| B．may easily get infected by diseases from dogs. |
| C．should not be allowed to have pets |
| D．should stop buying pets form Africa. |

I suddenly heard an elephant crying as though frightened. Looking down, I immediately recognized that something was wrong, and ran down to the edge of the near bank. There I saw Ma Shwe with her three-month-old calf struggling in the fast-rising water, and it was a life-and-death struggle. Her calf was floating and screaming with fear. Ma Shwe was as near to the far bank as she could get, holding her whole body against the rushing water, and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.
There was a sudden rise in the water and the calf was washed clean over the mother’s body and was gone. Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk against the rocky bank. Then with a huge effort, she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rock.
Just at this moment, she fell back into the river. If she were carried down, it would be certain death. I knew, as well as she did, that there was one spot where she could get up the bank, but it was on the other side from where she had put her calf.
While I was wondering what I could do next, I heard the sound of a mother’s love. Ma Shwe had crossed the river and got up the bank and was making her way back as fast as she could, roaring(吼叫) all the time, but to her calf it was music.The moment the author got down to the river bank he saw ___.
