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 programs 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 programs 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 programs 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 harmful 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. What is the main idea of the passage?
27. According to the passage, what do you think "Sesame Street" is?
28. What will be the consequence if a child forms a habit of watching hours of television every day?

选项 A、The degree of violence in programs is too high.
B、There shouldn’t be any commercials on television.
C、Watching too much television is undesirable for children.
D、Television programs in the United States are of low quality.

答案 C

解析 中心思想题。在听录音之前,预览四个选项可知本文与电视带来的负面影响有关。至于是对哪一方面的负面影响,既要根据主题句区分,还需要根据文章内容进行辨别。A,B,D选项都是对电视负面影响的具体描述,不能概括全篇。所以排除.故选C.
