　　答案及解析：

　　Section B

　　Passage One

　　Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school. And, by the time that the average child finishes high school, he or she will have spent 18,000 hours in front of a television set as opposed to 12,000 hours in a classroom.

　　Parents are concerned about these figures. They are also concerned about the lack of quality in television progmp3s for children. The degree of violence in many of these shows also worries them.

　　Even if it is unreal — a cartoon cat beating up a cartoon mouse with a baseball bat — this violence may have a negative effect on the young minds exposed to it. Studies indicate that, when children are exposed to violence, they may become aggressive or insecure.

　　Parents are also concerned about the commercials that their children see on television. Many parents would like to see fewer commercials during progmp3s for children. And some parents feel that these shows should not have commercials at all because young minds are not mature enough to deal with the claims made by advertisers.

　　Educational television has no commercials and has progmp3s for children that many parents approve of. The most famous of these is “Sesame Street”, which tries to give preschool children a head start in learning the alphabet and numbers. It also tries to teach children useful things about the world in which they live.

　　Even though most parents and educators give “Sesame Street” and shows like it high marks for quality, some critics argue that all television, whether educational or not, is hamp3ful to children. These critics feel that the habit of watching hours of television a day turns children into bored and passive consumers of their world rather than encouraging them to become active explorers of it.

　　Passage Two

　　Crime has its own cycles, a magazine reported some years ago. Police records show a surprising relation between changes in the season and crime patterns.

　　The pattern of crime has changed very little over a long period of years. Murder reaches its high during July and August, as do other violent attacks. Murder, in addition, is more than seasonal; it is a weekend crime. It is also a nighttime crime: 62 percent of murders are committed between 6 p.m. and 6 a.m. One is most likely to be robbed between 6 p.m. and 2 a.m. on a Saturday night in December, January, or February. Except for one strange statistic, May is the least criminal month of all.

　　Apparently our intellectual season cycles are completely different from our criminal patterns. Professor Huntington made a lot of studies to discover the seasons when people read serious books, attend scientific meetings, and make the highest scores on examinations. In all examples, he found a spring peak and an autumn peak separated by a summer low. On the other hand, Professor Huntington’s studies showed that June is the peak month for suicides and for admitting patients to mental hospital. June is also a peak month for marriages!

　　Possibly, high temperature and humidity bring on our strange and surprising summer actions, but police officers are not so sure. “There are, of course, no proof of a relation between humidity and murder”, they say. “Why murder’s high time should come in the summer time we really don’t know”.
