1、Gun Rights in the US Immediately after the shooting at Virginia Tech University, Americans gathered to mourn the dead. The president ａｎｄ　the state governｏｒboth hurried there to share the grief. But the majority of Americans still cling to their right to own weapons. Strictly speaking, the US is not the only country where gun violence has destroyed lives, families ａｎｄ　communities in everyday circumstance. But the US is one of the few countries that seems unwilling ａｎｄ　politically incapable of doing anything serious to stop it. In countries like Britain ａｎｄ　Canada. The government adopted stricter gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby ａｎｄ　the electoral system. The powerful National Rifle Association, the majｏｒsupporter of gun rights in the US, is too strong fｏｒany party to take on. Most Republicans oppose gun controls anyway. Over the years, the Democrats have found that they can either campaign fｏｒgun control ｏｒwin power, not both; they prefer power. According to the US Bureau of Justice Statistics, firearm incidents accounted ____ nine percent of the 4.7 million violent crimes in 2005. So, although opinion polls show most Americans want stricter gun laws, many don\'t want to give up their arms they keep to protect themselves. Dave Hancock, a Virginia gun lover, is one example. In an interview he said. "If one professｏｒin Virginia incident had been carrying a legal weapon they might have been able to stop all this. " In his opinion, the massacre is an argument fｏｒmore people to carry, weapons, not fewer. But at the root of Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government , commented UK\'s Guardian newspaper. One Virginia resident, who had a permit to carry; a concealed firearm, told the Guardian thin itwas every American\'s responsibility to have a gun. "Each person," he said, "should not rely solely on the government fｏｒprotection. " 【单选题】

2、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 finding could prove to be useful to ______.【单选题】

A.the analysis of cardiac cells

B.the prevention of chronic diseases

C.the treatment of heart diseases

D.the study of longstanding mysteries

正确答案:C

3、Flu doesScratchy throats, stuffy noses ａｎｄ　body aches all spell misery, but being able to tell if the cause is a cold ｏｒflu may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds ａｎｄ　the flu, ａｎｄ　one of the keys is being able to quickly tell the two apart. That\'s because the prescription drugs available fｏｒthe flu need to be taken soon after the illness sets in. As fｏｒcolds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold ａｎｄ　the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses-flu A, B ａｎｄ　C. There is no cure fｏｒeither illness, but the flu can be prevented by the flu vaccine (疫苗), which is, fｏｒmost people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although the flu ａｎｄ　common cold have many similarities, there are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose ａｎｄ　scratchy throat typically develop gradually, ａｎｄ　adults ａｎｄ　teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu fｏｒall ages. ａｎｄ　in general, flu symptoms including fever ａｎｄ　chills, sore throat ａｎｄ　body aches come on suddenly ａｎｄ　are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell when infants ａｎｄ　preschool age children have the flu. It advises parents to call the doctｏｒif their small children have flu-like symptoms.Both cold ａｎｄ　flu symptoms can be eased with over-the-counter medications as well. However, children ａｎｄ　teens with a cold ｏｒflu should not take aspirin fｏｒpain relief because of the risk of Reye syndrome (综合症), a rare but serious condition of the liver ａｎｄ　central nervous system.There is, of course, no vaccine fｏｒthe common cold but frequent hａｎｄ　washing ａｎｄ　avoiding close contact with people who have colds can reduce the likelihood of catching one.Which of the following symptoms will distinguish the flu from a cold?【单选题】

A.A stuffy nose.

B.A high temperature.

C.A sore throat.

D.A dry cough.

正确答案:B

答案解析:从第五段第二句可知“对于任何年龄段来讲发烧是流感的显著特征之一”。

4、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.A person with Parkinson-s has to learn to live with the disease, ______.【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:C

答案解析:本题难度不大，带着题干信息词回文章定位，答案依据是文章第四段前两句，谈到帕金森病还不能彻底治愈，但有几种药物可以控制症状使其变得容易忍受，回来看选项，C项和原文句意相符，是答案。
