Multiple Sclerosis (多发性硬化症 )
l. Multiple Sclerosis (MS) is a disease in which the patient&39;s immune (免疫的) system attacks the central nervous system. This can lead to numerous physical and mental symptoms, as the disease af-fects the transmission of electrical signals between the body and the brain. However, the human body,being a flexible, adaptable system, can compensate for some level of damage, so a person with MS can look and feel fine even though the disease is present.
2. MS patients can have one of two main varieties of the disease: the relapsing form. (复发型) and the primary progressive form. In the relapsing form, the disease progresses in a series of jumps; at times it is in remission (减轻) which means that a person&39;s normal functions return for a period of time before the system goes into relapse and the disease again becomes more active. This is the most com-mon form. of MS; 80～90% of people have this form. of the disease when they are first diagnosed. The relapse-remission cycle can continue for many years. Eventually, however, loss of physical and cogni-tive functions starts to take place and the remissions become less frequent.
3. In the primary progressive form. of MS, there are no remissions and a continual but steady loss of physical and cognitive functions takes place. This condition affects about 10~15 % of sufferers at di-agnosis.
4. The expected course of the disease, or prognosis (预后), depends on many variables: the sub-type of the disease, the patient&39;s individual characteristics and the initial symptoms. Life expectancy of patients, however, is often nearly the same as that of an unaffected person-provided that a reasona- le standard of care is received. In some cases a near-normal life span is possible.
5. The cause of the disease is unclear; it seems that some people have a genetic susceptibility(易感性) , which is triggered by some unknown environmental factor. Onset (发作) of the disease usually occurs in young adults between the ages of 20 and 40. It is more common in women than men; howev-er, it has also been diagnosed in young children and in elderly people.

参考答案
问题 1 答案解析：
??B；第一段主要讲述多发性硬化症的定义及其症状。所以本题选“The Definition of MS”（多发性硬化症的定义），故选B??
问题 2 答案解析：
??A；第二段主要讲述复发型多发性硬化症相关的内容。所以本题选“The Relapsing Form. of MS”（复发型多发性硬化症），故选A??
问题 3 答案解析：
??F；第三段主要讲述原发进展型多发性硬化症的相关内容。所以本题选“The Primary Progressive Form. of MS”（原发进展型多发性硬化症），故选F。??
问题 4 答案解析：
??D；第四段主要讲述患多发性硬化症的后果。所以本题选“The Development of MS”（多发性硬化症的发展），故选D。??
问题 5 答案解析：
??B；句意：多发性硬化症影响年轻人躯体和……之间的神经细胞的联络。根据第一段第二句后半句“as the disease affects the transmission of electrical signals between the body and the brain”可知应选多发性硬化症影响躯体与大脑间的电信号传输。故选B。??
问题 6 答案解析：
??E；句意：多发性硬化症患者可以不受……的影响很好地生活多年。根据第一段最后一句“However，the human body，being a flexible，adaptable system，can com-pensate for some level of damage, so a person with MS can look and feel fine even though the disease is present.”可知，由于人体的灵活性与适应性多少可以补偿因疾病所造成的损害，所以病人仍可不受疾病的影响，看起来很好，故选E。??
问题 7 答案解析：
??F；句意：io%～15%的患者被诊断为……。第三段讲述原发进展型多发性硬化症的相关内容，由最后一句“This condition affects about 10～15% of sufferers at diagnosis.“可获知此项应为“原发进展型多发性硬化症”，故选F??
问题 8 答案解析：
??A；句意：年轻成人比……得此病的几率更高。根据文章最后一段最后两句“Onset of the disease usually occurs in young adults between the ages of 20 and 40. It is more common " women than men; however, it has also been diagnosed in young children and in elderly people.”，可知患此病的人通常年龄在20岁到40岁之间，故选A。??
