Facts about Stroke
1Every 45 seconds, someone in America has a stroke. Every 3.1 minutes, someone dies of one.
Stroke killed an estimated 167,661 people in 2000 and is the nation&39;s third leading cause of death, ranking behind diseases of the heart and all forms of cancer. Stroke is a leading cause of serious ,long-term disability in the United States.
2 Stroke is a type of cardiovascular(心血管的) disease. It affects the arteries(动脉) leading to and within the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients(营养物) to the brain is either blocked by a clot(凝块) or bursts. When that happens,part of the brain cannot get the blood(and oxygen)it needs,so it starts to die.
3The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow can&39;t reach the region that controls a particular body function, that part of the body won&39;t work as it should. If the stroke occurs toward the back of the brain, for instance, it&39;s likely that some disability involving vision will result. The effects of a stroke depend primarily on the location of the obstruction(阻塞) and the extent of brain tissue affected.
4The American Stroke Association has identified several factors that increase the risk of stroke.
The more risk factors a persor has,the greater the chance that he or she will have a stroke. Some of these you can&39;t control, such as increasing age, family health history, race, and prior stroke. But you can change or treat other risk factors to lower your risk. Factors resulting from lifestyle. or envi-ronment can be modified with a healthcare provider&39;s help. Some of these include : high blood pres-sure,current smoking,heart disease,and high red blood cell count.
5A stroke can happen to anyone at any moment. In fact about 600,000 people have strokes every year. For many years, there was no hope for those suffering a stroke. However, recent break-throughs have led to new treatments. For the treatments to work, the person must get to a hospital immediately.

What Is Death？
People in the past did not question the difference between life and death. They could see that a person died when his heart stopped beating. People have learned, however, that the body does not die immediately when the heart stops beating. They discovered that we remain alive as long as our brain remains active. Today the difference between life and death is not as easy to see as in the past. Modern medical devices can keep the heart beating and the lungs breathing long after the brain stops. But is this life？
This question has caused much debate among citizens in the United States. Many of them want a law that says a person is dead when the brain dies. A person should be considered dead when brain waves stop even if machines can keep the body alive. Such a law would permit doctors to speed removal (切除) of undiseased (没病的) organs for transplant (移植) operations.
The brain is made of thousands of millions of nerve cells. These cells send and receive millions of chemical and electrical messages every day. In this way the brain controls the other body activities. Nerve-cell experts say it usually is easy to tell when the brain has died. They put small electrodes (电极) on a person's skull (头骨) to measure the electrical signals that pass in and out of the brain. These brain waves are recorded on a television screen or on paper. The waves move up and down every time the brain receives messages from the nerve cells. The brain is dead when the waves stop moving.
Although there are people who oppose the idea of a law on brain block for variouis reasons, the idea of brain wave activity as a test of death is slowly being accepted.
People in the past held that the difference between life and death______.
A．was easy to tell
B．did not exist
C．lay in the brain
D．was open to debate
