    Facts about Stroke
    1. Every 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'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.
    3. The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow can't reach the region that controls a particular body function,that part of the body won't work as it should. If the stroke occurs toward the back of the brain,for instance,it'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.
    4. The American Stroke Association has identified several factors that increase the risk of stroke.
    The more risk factors a person has,the greater the chance that he or she will have a stroke.Some of these you can'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 environment can be modified with a healthcare provider's help.Some of these include:high blood pressure,current smoking,heart disease,and high red blood cell count.
    5. A 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 breakthroughs have led to new treatments.For the treatments to work,the person must get to a hospital immediately.

    Paragraph 3_________
    A: Effects of a stroke
    B: Annual cost of stroke in the US
    C: Definition and description of a stroke
    D: Breakthroughs in treatment
    E: Risk factors of stroke
    F: Warning signs of a stroke

    本段列举了一些经过美国中风学会证实的危险因素,并对它们是否可预防加以分析。


    本段说,多年以来,中风病人是毫无希望的,不过现在已有一些突破,只要及时送到医院,新的治疗方法就可能起作用。


    第二段第二句说的就是中风影响到通向大脑的动脉以及大脑里面的动脉。


    第三段第三句说的就是如果中风发生于大脑的后部,病人的视力就会受到某种程度的影响。


    第四段后半部分说到,有些因为生活方式及环境造成的危险因素是可以改变的,从而可以降低中风的危险性。


    第五段说到,现在对中风病人已经有了一些新的疗法,只要将病人及时送到医院就有希望。
