1、Musical Training Can Improve Communication Skills American scientists say musical training seems to improve communication skills and language retardation. They found that developing musical skills involves the same process in the brain as learning how to speak. The scientists believe that could help children with learning disabilities. Nina Kraus is a neurobiologist at Northwestern University in Illinois. She says musical training involves putting together different kinds of information, such as hearing music, looking at musical notes, touching an instrument and watching other musicians. This process is not much different from learning how to speak. Both involve different senses. She further explains musical training and learning to speak each make us think about what we are doing. She says speech and music pass through a structure of the nervous system called the brain stem. The brain stem controls our ability to hear. Until recently, experts have thought the brain stem could not be developed or changed. But Professor Kranss and her team found that musical training can improve a person\'s brain stem activity. The study involved individuals with different levels of musical ability. They were asked to wear an electrical device that measures brain activity. The individuals wore the electrode while they watched a video of someone speaking and a person playing a musical instrument ---- the cello. ____ The study found that the more years of training people had, the more sensitive they were to the sound and rhythm of the music. Those who were involved in musical activities were the same people in whom the improvement of sensory events was the strongest. It shows the importance of musical training to children with learning disabilities. She says using music to improve listening skills could mean they hear sentences and understand facial expressions better. 【单选题】

A.Both involve different senses.

B.Nina Kraus is a neurobiologist at Northwestern University in Illinois.

C.Some disabled children attended the musical training Class.

D.It shows the importance of musical training to children with learning disabilities.

E.Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech.

F.The brain stem controls our ability to hear.

正确答案:E

答案解析:同上面第三题的解释一样，选项E的句子中出现特指的the cellos，与上一句的cello相呼应，该句说明科学家为什么要选择大提琴作为音乐训练的乐器，上下文意思连贯，所以E是答案。

2、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。

3、PopulationThe advantages and disadvantages of large population have long been a subject of discussion among economists. It has been argued that the supply of good land is limited . To feed a large population, inferior land must be cultivated and the good land worked intensively. produces less and this means a lower average income than could be obtained with a smaller population . Other economists have argued that a large population gives more scope for specialization and the development of facilities such as ports, roads and railways, which are not likely to be built unless there is a big demand to justify themOne of the difficulties in carrying out a worldwide birth control program lies in the fact that official attitudes to population growth vary from country to country depending on the level of industrial development and the availability of food and raw materials. In the developing country where a vastly expanded population is pressing hard upon the limits of food, space and natural resources, concern of government to plane a limit on the birth rate, whatever the consequences may be. In a highly industrialized society the problem may be more complex. A decreasing birth rate may lead to unemployment ____. When the pressure of population on housing declines, prices also decline and the building industry is weakened. Faced with considerations such as these, the government of a developed country may well prefer to see a slowly increasing population, rather than one which is stable or in decline.【单选题】

A.which are not likely to be built unless there is a big demand to justify them

B.It has been argued that the supply of good land is limited

C.it will be the first concern of government to plane a limit on the birth rate, whatever the consequences may be

D.Thus, each person produces less and this means a lower average income than could be obtained with a smaller population

E.A small population may mean lower productivity, but a higher average income

F.because it results in a declining market for manufactured goods

正确答案:F

答案解析:根据空白处前面的半句话可以找出在语义上和逻辑上都与之连贯的选项。由于人口减少，需求量变小，制成品的市场萎缩，从而导致失业，造成社会问题。逻辑推理是解决该题的重点。

5、Human Heart Can Make New CellsSolving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac 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 for the treatment of heart diseases such as heart failure and heart attack, experts say. "We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professor of 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 or if they could be renewed," he said. The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover 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 that promote this process to stimulate regeneration after for example, 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-author Dr. Ratan Bhardwaj. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said. With this finding, scientists are "opening the door to potential therapies 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.Chronic heart failure is attributed to ____.【单选题】

A.the dying heart cells

B.the effect of pharmceutical

C.the weight of a patient

D.the life span of a person

正确答案:A

答案解析:倒数第三段说：Chronic heart failure arises from heart cells dying。慢性心衰是由心肌细胞死亡导致的。
