1、Parkinson\'s Disease1. 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 fｏｒsure what makes these nerve cells break down. But scientists are doing a lot of research to look fｏｒthe 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. Tremｏｒoften starts in just one arm ｏｒleg ｏｒonly on one side of the body. It may be worse when you are awake but not moving the affected arm ｏｒleg. It may get better when you move the limb ｏｒyou are asleep. In time, Parkinson\'s affects muscles all through your body, so it can lead to problems like trouble swallowing ｏｒconstipation(便秘) . In the later stages of the disease, a person with Parkinson\'s may have a fixed ｏｒblank expression, trouble speaking, ａｎｄ　other problems. Some people also have a decrease in mental skills.4. At this time, there is no cure fｏｒParkinson\'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 not obvious. Your doctｏｒmay wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctｏｒwill adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.One of the most common signs of Parkinson\'s is tremor, ______.【单选题】

A.if there isn’t enough dopamine in your body

B.what affects muscles all through your body

C.which cannot be cured yet

D.if you have a fixed ｏｒblank expression

E.which may be the first symptom you notice

F.what causes Parkinson\'s disease

正确答案:E

答案解析:本题难度不大，带着题干信息词回文章定位，答案依据是文章第三段的第一句：Tremｏｒmay be the first symptom you notice，谈到颤抖会是你注意到的第一个症状，回来看选项，E项和原文句意相符，是答案。

2、We\'ve?been?through?some?rough?times?together.【单选题】

A.short

B.difficult

C.long

D.happy

正确答案:B

答案解析:题干大意：我们一起渡过了一些困境。句中rough意为“粗糙的、艰苦的”。rough?time意为“困难时刻”，和四个选项中的difficult?time意思一样。short意为“短的”；long意为“长的”；happy意为“幸福的”，与rough意义相反。

3、Human Heart Can Make New CellsSolving a longstanding (为时甚久的) mystery, scientists have found that the human heart continues to generate new cardiac(心脏的 ) cells throughout the life span, although the rate of new cell production slows with age.The finding, published in the April 3 issue of Science, could open a new path fｏｒthe treatment of heart diseases such as heart failure ａｎｄ　heart attack, experts say."We find that the beating cells in the heart, cardiomyocytes (心肌细胞), are renewed," said lead researcher Dr. Jonas Frisen, a professｏｒof stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with ｏｒif they could be renewed," he said.The process of renewing these cells changes over time, Frisen added. In a 20 - year - old, about I percent of cardiomyocytes are exchanged each year, but the turnover (更替) rate decreases with age to only 0.45 percent by age 75."If we can understａｎｄ　how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals (药物) that promote this process to stimulate regeneration after, fｏｒexample, a heart attack," Frisen said.That could lead to treatment that helps restore damaged hearts."A lot of people suffer from chronic heart failure," noted co - authｏｒDr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.With this finding, scientists are "opening the doｏｒto potential therapies (疗法) to having ourselves heal ourselves." Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new ａｎｄ　more cells to overcome the problem they are facing. "But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.The human heart stops producing cardiac cells ______.【单选题】

A.when a person becomes old

B.as soon as a person gets sick

C.immediately after a person is born

D.once a person dies

正确答案:D

答案解析:本题有一定难度，需要吃透原文句意，答案依据是文章第一段，谈到科学家发现人一生中心脏都会不停地制造新的心肌细胞，尽管新细胞产生的速度随年龄增长而放慢，换句话说，只有人死了，心脏才会停止制造心肌细胞，回来看选项，D项和原文句意相符，是答案。

4、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US ａｎｄ　one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few vials. ａｎｄ　the last “official” stocks of live virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US ａｎｄ　Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus ____ useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

A.will?be

B.would?be

C.is

D.are

正确答案:C

答案解析:本句是个条件句。从句中动词一般用现在时表示“未来”。这就排除了will?be和would?be。virus是单数，因此D也不正确。故C为正确答案。

5、ExerciseWhether ｏｒnot exercise adds to the length of life, it is common experience that a certain amount of regular exercise improves the health ａｎｄ　contributes a feeling of well-being. Furthermore, exercise which involves play ａｎｄ　recreation, ａｎｄ　relieves nervous tension ａｎｄ　mental fatigue in so doing, is not only pleasant but beneficial.How much ａｎｄ　what kind of exercise one should take merits careful consideration. The growing child ａｎｄ　the normal young man ａｎｄ　young woman thrill with the exhilaration of strenuous sports. They fatigue to the point of exhaustion but recover promptly with a period of rest. But not so with those of middle age ａｎｄ　beyond. Fｏｒthem moderation is of vital importance. Just how much exercise a person of a given age can safely take is a question hard to answer. Individual variability is too great to permit of generalization. A game of tennis may be perfectly safe fｏｒone person of forty but folly fｏｒanother. The safe ｌｉｍｉｔfｏｒexercise depends on the condition of the heart, the condition of the muscles, the type of exercise, ａｎｄ　the regularity with which it is taken. Two general suggestions, however, will serve as sound advice fｏｒanyone. The first is that the condition of the heart ａｎｄ　general health should be determined periodically by careful, thorough physical examinations. The ____ is that exercise should be kept below the point of physical exhaustion.What type of exercise one should choose depends upon one\'s physical condition. Young people can safely enjoy vigorous competitive sports, but most older persons do bet ter to ｌｉｍｉｔthemselves to less strenuous activities. Walking, swimming, skating are among the sports that one can enjoy ａｎｄ　safely participate in throughout life. Regularity is important if one is to get the most enjoyment ａｎｄ　benefit out of exercise.【单选题】
