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.You\'ll find it hard to move the way you want to ______.【单选题】

4、TV Games Shows One of the most fascinating things about television is the size of the audience. A novel can be on the "best sellers" list with a sale of fewer than 100,000 copies, but a popular TV show might have 70 million TV viewers. TV can make anything or anyone well known overnight. This is the principle behind "quiz" or "game" shows, which put ordinary people on TV to play a game for the prize and money. A quiz show can make anyone a star, and it can give away thousands of dollars just for fun. But all of this money can create problems. For instance, in the 1950s, quiz shows were very popular in the U. S. and almost everyone watched them. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show\'s producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn\'t like the person who won the game, they turned the show off. Based on his story, a movie under the title " Quiz Show" is on 40 years later. Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren\'t taken as seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions. The principle behind "quiz" or "game" shows is to put ordinary people on TV to play a game for prizes and money. 【单选题】

A. Right

B. Wrong

C.Not mentioned

正确答案:B

答案解析:该句是说“猜谜节目背后的原则是为了让普通人参加赢取奖品和奖金的电视节目”。答案查找的线索词： ordinary people（普通人）。从第二段开始查找（因为问题一的答案在第一句的结尾），不难在第二段的第一句中找到含有ordinary people的相关句。对照原句和问题句，不难发现原句的结构与问题句的结构有所不同：原句中有代词this，说“这就是猜谜节目背后的原则”，而代词往往指代前一句的内容，可见TV can make anything or anyone well-known overnight. 才是猜谜节目背后的原则。所以该句说法错误。

5、Smoking Can Increase Depressive Symptoms in TeensWhile some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens."This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating ____ or to improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools located in high, moderate and low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical state; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; and worried too much about things."Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O\'Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression and smoking exists principally among teens that use cigarettes to feel better. "It\'s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.【单选题】

A.effects

B.methods

C.steps

D.directions

正确答案:A

答案解析:句中的or是“即”，也就是说，to have self-medicating加上填入的词之后的意思相当于to improve mood。四个选项中只有选项A的effects（效果）是填入空格的最合适的词。to improve mood是自我治疗的效果。其他三个选项methods、steps、directions与self-medicating连用，意思分别为“自我治疗的方法”、“自我治疗的步骤”、“自我治疗的指导”，与句子的意思不相配。
