As the pace of life continues to increase, we are fast losing the art of relaxation.   5   you are in the habit of rushing through life, being on the go from morning till night, it is hard to    6     down. But relaxation is 7 for a healthy mind and body.

Stress is a 8 part of everyday life and there is no way to 9 it. In fact, it is not the bad thing that it is often supposed to be. A 10 amount of stress is important to provide motivation and give    11    to life.

It is only when the stress gets out of control 12 it can lead to poor performance and  13 health.

The amount of stress a person can bear 14 very much on the individual. Some people are not afraid of stress, and such 15 are obviously chief material for managerial responsibilities. Others lose heart at first 16 of unusual difficulties. When exposed to stress, in 17 form, we react both chemically and physically. In fact we make a choice between 18 and fight. And in more ancient days the choices made the 19 between life and death. The crises (危机)we meet today are 20 to be so extreme, but however little the stress is, it requires the same response. It is when such a reaction 21 long through continued exposure to stress, that health becomes 22 Such serious conditions as high blood pressure and heart diseases have 23 links with stress. 24 we cannot remove stress from our lives we need to find ways to deal with it. It would be unwise to do so even if we could.

So what do you think of stress? What is your way to deal with it?

The virus "Ebola" is named after the Ebola River in what is now the Democratic Republic of the Congo. That's where the virus was discovered in 1976. A per?son can only get Ebola through direct contact with an in?fected person's bodily fluids, for example, sweat or spit. Additionally, the virus can get into your body through your eyes and mouth if those areas come into contact with something that contains the bodily fluids of an infected person. That's why health care workers are supposed to keep themselves completely covered while treating patients.

The deadliest Ebola outbreak is spreading fast in West Africa, taking over 900 lives so far. The health systems in Guinea, Sierra Leone and Liberia are severe?ly lacking resources, and health care workers may not have access to adequate protective clothing when work?ing in rural clinics, where the proper protections are lac?king. Since Guinea, Sierra Leone and Liberia share a border, it's easier for people to move from one country to another, increasing the risk for disease spread. Infec?ted people may be kept separate with other people infec?ted with the disease, making this kind of contact easier.

The virus has a 2-to-21-day incubation(潜伏)peri?od. It is systemic and can move to and affect every part of the body, causing direct damage to organs and inter?nal bleeding. This causes shock, dropping a person's blood pressure and causing multi-system organ failure.

For now, all doctors can do is treat the symptoms and provide supportive care like monitoring heart rate, blood pressure, and breathing while making sure the patients' fluids are supplied. Sometimes patients are given antibiotics(抗生素)to treat other possible infections. The hope is to make the patients pull through the infec?tion so their immune systems can eventually clear the vi?rus. The people who survive Ebola have created enough antibodies to kill it. This is harder to achieve in rural health systems in West Africa that are tasked with trea?ting thousands of patients with poor resources.

There are several promising drugs and vaccines in development, but since Ebola is less common―and re?search about it is not well funded―there is no drug or vaccine that has been approved for use in humans. Many of the other drugs and vaccines have not yet been tested in humans. The WHO (World Health Organization) is meeting next week to discuss whether experimental treatments should be used during this outbreak.
