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 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 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 not obvious. 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.A lot of research is being done to find out ______.【单选题】

2、College Night Owls Have Lower GradesCollege students who are morning people tend to get better grades than those who are night owls(晚睡的人), according to University of North Texas researchers.They had 824 undergraduate(大学本科生的) students complete a health survey that in cluded questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages(GPAs) than those who are night people."The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co - author Daniet J. Taylor said in a prepared statement."Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylor said.The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional (专业的) Sleep Societies, in Baltimore.In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠) and a decline in college students\' academic performance.The study included 64 psychology, nursing and medical students, average age 27. 4 years, who were divided into two groups—low GPAs and high GPAs.Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks or twitches (痉挛) at night, 65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day."In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study author Dr. James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student\'s academic performance, including GPAs."The passage indicates that chronotherapy can be used to help people to ______. 【单选题】

4、Online Cancer Chat with a Safety NetCancer Research UK has launched an online chat forum for cancer patients to swap (变换) stories and share experiences on how to cope with such a devastating disease.But Cancer Chat is a forum with a difference: it has an information safety net.This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue (劣等的) "cancer cures" or scientifically unsound information.Anyone can have access to the messages posted on Cancer Chat, but if people wish to post a message, they will need to register.And Rebekah Gibbs, cancer patient and star of TWs Casualty, has pledged her support for the new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer and I have had such a heart - warming response from other people going through the same thing."The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family. And with Cancer Research UK monitoring the forum, people can be reassured about the quality of information being exchanged.Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website, which is specially designed to give patients and their families 6,000 pages of up - to - date information that is easy to understand and explains a wide range of treatments for different types of cancer and gives details of clinical trials. There is also a UK database of cancer clinical trials.The award - winning website attracts around one million visitors a month and Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum.For those who do not have access to computers and have questions about cancer, the charity\'s team of cancer information nurses are available during office hours to talk over patients\' concerns on the phone.Cancer Chat is different from other forums chiefly in that ______.【单选题】

A.it has the support of a famous actress

C.it is a source of reliable information

D.it attracts a great number of visitors

5、The IcemanOn a September day in 1991, two Germans were climbing the mountains between Austria and Italy. High up on a mountain pass, they found the body of a man lying on the ice. At that height (10,499 feet, or 3 ,200 meters) , the ice is usually permanent, but 1991 had been an especially warm year. The mountain ice had melted more than usual and so the body had come to the surface.It was lying face downward. The skeleton (骨架) was in perfect condition, except for a wound in the head, There was still skin on the bones and the remains of some clothes. The hands were still holding the wooden handle of an ax and on the feet there were very simple leather and cloth hoots. Nearby was a pair of gloves made of tree bark (树皮) and a holder for arrows.Who was this man? How and when had he died? Everybody had a different answer to these questions. Some people thought that it was from this century, perhaps the body of a soldier who died in World War I, since several soldiers had already been found in the area. A Swiss woman believed it might be her father, who had died in those mountains twenty years before and whose body had never been found. The scientists who rushed to look at the body thought it was probably much older, maybe even a thousand years old.With modern dating techniques, the scientists soon learned that the Iceman was about 5,300 years old. Born in about 3300 B. C. , he lived during the Bronze Age in Europe. At first scientists thought he was probably a hunter who had died from an accident in the high mountains. More recent evidence, however, tells a different story, A new kind of X - ray shows an arrowhead still stuck in his shoulder. It left only a tiny hole in his skin, but it caused internal damage and bleeding. He almost certainly died from this wound, and not from the wound on the back of his head. This means that he was probably in some kind of a battle. It may have been part of a larger war, or he may have been fighting bandits. He may even have been a bandit himself.By studying his clothes and tools, scientists have already learned a great deal from the Iceman about the times he lived in. We may never know the full story of how he died, but he has given us important clues to the history of those distant times.All the following are assumptions once made about the Iceman EXCEPT ______.【单选题】

A.he was a soldier in World War I

B.he was a Swiss woman\'s long - lost father

C.he was born about a thousand years ago

D.he came from Italy

正确答案:D

答案解析:本题有一定难度，首先要读懂题干，好多考生因为没有读懂而做错。第三段谈到了对冰人的各种猜测：有人认为他是一战的士兵；一位瑞士女人坚信冰人是她二十年前死在山里的父亲，科学家们认为他大概有一千年的历史了，惟独没有提到冰人是意大利人的猜测，所以答案是D。
