2、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.Paragraph 2 ______【单选题】

A.Tips for Patients with the Disease

B.Common Treatment for the Disease

C.Means of Diagnosis of the Disease

D.Typical Symptoms of the Disease

E.Possible Causes of the Disease

F.Definition of Parkinson\'s Disease

3、Early childhood educationIn a time of low academic achievement by children in the United States, many Americans are turning to Japan, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find in most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japanese children are taught to read at home by their parents.In the recent comparison of Japanese and American preschool education, 91 percent of Japanese respondents chose providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented (强调个性发展的) Americans listed group experience as one of their top three choices. An emphasis on the importance of the group seen in Japanese early childhood education continues into elementary school education.Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the children\'s chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.We learn from the first paragraph that many Americans believe ____.【单选题】

A.Japanese parents are more involved in preschool education than American parents

B.Japan\'s economic success is a result of its scientific achievements

C.Japanese preschool education emphasizes academic instruction

D.Japan\'s higher education is superior to theirs

正确答案:C

答案解析:从第一段的前三句话中我们可以很容易地看出“美国儿童学业成绩较低的情况，许多美国人试着把孩子送到日本读书，那里经济发达而且儿童学业成绩不错。然而，日本学前教育的情况并不像美国家长所期待的那样。在大多数的日本学前班里，知识的教授仅占很小的比重。”故C正确。

4、Egypt Felled by Famine Even ancient Egypt\'s mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same or worse could happen today. The ancient Egyptians depended on the Nile\'s annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods. Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile. The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt\'s Old Kingdom. The weakened waters would have been catastrophic for the Egyptians. " Changes that affect food supply don\'t have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York. "Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. " Why does the author mention "pyramid builders " ? 【单选题】

A.Because they once worked miracles.

B.Because they were well-built.

C.Because they were actually very weak.

D.Because even they were unable to rescue their civilization.

正确答案:D

答案解析: D：甚至是他们也不能挽救他们的文明。因此D是正确的答案。A：他们曾创造过奇迹。B:他们很强壮。C：他们其实很弱。

5、MemoriesMost episodes of absent-mindedness forgetting where you left something or wondering why you just entered a room are caused by a simple lack of attention, says Schacter. "You are supposed to remember something, but you haven\'t encoded it deeply."Encoding, Schacter says, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don\'t pay attention to what you did because you are involved in a conversation, you will probably forget that the phone is in the jacket now hanging in your wardrobe. "Your memory itself isn\'t failing you," says Schacter. " ____. "Lack of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to drop a letter in the mailbox. " Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that.Visual cues can help prevent absent-mindedness, says Sclnacter." But be sure the cue is clear and available.,"he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table don\'t leave it in the medicine chest and write yourself a note that you keep in a pocket.Another common episode of absent-mindedness: walking into a room and wondering why you are there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, and you will likely remember.【单选题】
