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.
Questions 26 to 28 are based on the passage you have just heard.
26. What is the main idea of the passage?
【解析】選[C]。在聽錄音之前，預覽四個選項可知本文與電視帶來的負面影響有關。至于是對哪一方面的負面影響，既要根據主題句區分，還需要根據文章內容進行辨別。
27. According to the passage, what do you think “Sesame Street” is?
【解析】選[B]。預讀選項可知此題詢問的是電視節目的類型。The most famous of these is “Sesame Street”...為答案的依據，其中的these指的就是educational progmp3s.
28. What will be the consequence if a child fomp3s a habit of watching hours of television every day?
【解析】選[A]。預讀選項可知此題詢問的是They將會發生什么行為或變成怎樣的狀態，需要留意對動作和狀態的描述。答案依據為：These critics feel that the habit of watching hours of television day turns children into bored and passive consumers of their world rather than encouraging them to become active explorers of it. 選項[A]中bored ≈ 原文中的dull，passive ≈ inactive。
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”.
Questions 29 to 31 are based on the passage you have just heard.
29. What is the passage mainly about?
【解析】選[D]。根據選項的概括性強、信息密集可知，本題考查短文主旨。文章開頭的Police records show a surprising relation between changes in the season and crime patterns為短文主題句，故[D]為答案。
30. Which is the safest season?
【解析】選[B]。文章明確提到May is the least criminal month of all，表明五月是犯罪率最低的月份，也就是說五月最安全，故選項[B]正確。
31. What did Professor Huntington’s research show?
【解析】選[C]。推斷題。文章講到，Professor Huntington調查人們讀嚴肅小說、出席科技會議和考試得高分的季節，所有數據表明在春季和秋季是高峰，而夏季卻是低峰，排除[B]、[D];另外短文中聽到June出現最多的地方提到了兩個peak, 他們分別是自殺和醫院接收精神病患者數目最高峰以及結婚的高峰，由此可以排除[A]項，得出答案[C]。
