问题 共用题干 Parkinson's Disease

1 Parkinson's disease affects the way you move.It happens when there is a problem with certain nerve
cells in the brain. Normally , these nerve cells make an important chemical called dopamine(多巴胺).
Dopamine sends signals to the part of your brain that controls movement.It lets your muscles move smoothly
and do what you want them to do.When you have Parkinson's,these nerve cells break down.Then you no
longer have enough dopamine,and you have trouble moving the way you want to.
2 No one knows for sure what makes these nerve cells break down.But scientists are doing a lot of
research to look for the answer. They are studying many possible causes,including aging and poisons in the
environment.Abnormal genes seem to lead to Parkinson's disease in some people.But so far,there is not
enough proof to show that it is always inherited.
3 Tremor(颤抖)may be the first symptom you notice.It is one of the most common signs of the
disease,although not everyone has it.Tremor often starts in just one arm or leg or only on one side of the
body.It may be worse when you are awake but not moving the affected arm or leg.It may get better when you
move the limb or when you are asleep.In time,Parkinson's affects muscles all through your body,so it can
lead to problems like trouble swallowing or constipation(便秘).In the later stages of the disease,a person
with Parkinson's may have a fixed or blank expression,trouble" speaking,and other problems.Some people
also have a decrease in mental skills.
4 At this time,there is no cure for Parkinson's disease.But there are several types of medicines that
can control the symptoms and make the disease easier to live with.You may not even need treatment if your
symptoms are mild.Your doctor may wait to prescribe medicines until your symptoms start to get in the way of
your daily life.Your doctor will adjust your medicines as your symptoms get worse.You may need to take
several medicines to get the best results.
选项 A lot of research is being done to find out__________. A:what affects muscles all through your body B:if there isn't enough dopamine in your body C:which cannot be cured yet D:which may be the first symptom you notice E:if you have a fixed or blank expression F: what causes Parkinson's disease
答案 F
解析 即帕金森综合征的定义。本段的中心意思是“什么是帕金森综合征”。
即导致疾病产生的可能的原因。本段主要探讨的是这种疾病发生的原因。

即通常的治疗方法。从本段可知,虽然帕金森综合征还不能治愈,但是可以通过几种 药物控制患者的病情。
即如果没有足够的多巴胺你会发现自己难以随心所欲地行动。根据第一段最后一句 "Then you no longer have enough dopamine,and you have trouble moving the way you want to.”可 知,本题应选B。
即科学家做了很多研究试图发现导致帕金森综合征的原因。从第二段第一句“No one knows for sure what makes these nerve cells break down.”可知,本题应选F。
即帕金森病最常见的病症是颤抖,它可能是你发现的第一个症状。从第三段第一句 "Tremor (颤抖)may be the first symptom you notice.”可知,本题应选D。
患帕金森综合征的人必须学会和这种疾病共处,因为现在人们还无法治愈它。从最后 一段第一句“At this time, there is no cure for Parkinson's disease.”可知,本题应选C。第4部分:阅读理解第一篇 本篇文章主要介绍了心脏在人的生命过程中产生新的心肌细胞的能力。
