Reading Comprehension Directions: There are 1 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. You should decide on the best choice.Passage 1While it is true that Americans believe climbing the educational ladder leads to success, they are less certain that intellectual achievement, which is main purpose of the schools, is the only important factor leading to success. A competitive-even aggressive-personality is seen as important to success, especially in men.The development of social and political skills is also considered to be very important. To help Americans develop these other important skills, schools have added a large number of extracurricular activities to daily life at school. This is especially true of high school and colleges but extends down into elementary schools as well. Athletics, frequently called “competitive sports”, are perhaps the most important of these activities. Football, basketball, and baseball teams are seen as very important in students, particularly boys, the “winning spirit”. At times, athletic teams seem to become more important to some students and their parents than the academic programs offered by the schools.Student government is another extracurricular activity designed to develop competitive, political, and social skills in students. The students choose a number of student government officers, who compete for the votes of their fellow students in schoolwide elections. Although these officers have little power over the central decisions of the school, the process of running for minor matters if elected is seen as good experience in developing their leadership and competitive skills.Athletics and student government are only two of a variety of extracurricular activities found in American schools. There are clubs and activities for almost every student interest, all aimed at helping the student to become more successful in later life. Many parents watch their childrens extracurricular activities with as much interest and concern as they do their childrens intellectual achievements in the classroom.1.

Developing leadership and competitive skillsPassage 2Spending 50 minutes with a cell phone close to your ear is enough to change brain cell activity in the part of the brain closest to the antenna (天线). But whether that causes any harm is not clear, scientists at the National Institute of Health said at a conference last month, adding that the study will not likely settle concerns of a link between cell phones and brain cancer. “What we showed is glucose (葡萄糖) metabolism(代谢)(a sign of brain activity) increases in the brain in people who were exposed to a cell phone in the area closest to the antenna,” said Dr. Nora Volkow of the NIH, whose study was published in the Journal of the American Medical Association. The study was meant to examine how the brain reacts to electromagnetic fields caused by wireless phone signals.Volkow said she was surprised that the weak electromagnetic radiation(电磁辐射) from cell phones could affect brain activity, but she said the findings do not shed any light on whether cell phones cause cancer. “This study does not in any way indicate that. What the study does is to show the human brain is sensitive to electromagnetic radiation from cell phone exposures.” Use of the devices has increased dramatically since they were introduced in the early 1980s, with about 5 billion cell phones now in use worldwide.Some studies have linked cell phone exposure to an increased risk of brain cancers, but a large study by the World Health Organization did not offer a clear answer to this. Volkows team studied 47 people who had their brain examined while a cell phone was turned on for 50 minutes and another while the phone was turned off. While there was no complete change in brain metabolism, they found a 7 percent increase in brain metabolism in the region closest to the cell phone antenna when the phone was on.Experts said the results were interesting, but urged that they be understood with great care. “ Although the biological significance, if any, of increased glucose metabolism from too much cell phone exposure is unknown, the results require further investigation,” Henry Lai of the University of Washington in the U.S. and Dr. Lennart Hardell of University Hospital in Sweden, wrote in an article in JAMA. “Much has to be done to further investigate and understand these effects.” They wrote.6.
