传媒的作用：
111 "The worldwide distribution of television programs and advertisements is seriously diminishing the differences among cultures."
151. "High-speed electronic communications media, such as electronic mail and television, tend to prevent meaningful and thoughtful communication."
a) 现代的通信有助于交流，比如电话，email等，效率很高，而且很快。可以达到及时交流的目的，十分方便。比如你和你的父母离的很远，书信方式显然很慢，而电话或者邮件，既省时间，又可以随时的达到沟通,可以让它们及时了解你的情况。
b) 在人与人交往方面，阻止了meaningful，thoughtful的交流。Meaningful，thoughtful的交流需要面对面，有肢体语言作为辅助，很生动形象。比如一对情侣会以接吻的方式来表达对对方的爱，一个母亲会用抚摸孩子的方式来表达对孩子的关心等等，然而目前所有的高速交流方式都达不到这个要求。即便是可视电话，虽然可以看到对方的相貌，但是仍然不能让对方得到你的拥抱或者热吻。
c) 在学习知识方面，这些通讯工具阻止了meaningful，thoughtful的交流。听老师讲课是一种互动的过程，可以提问，老师的回答帮助更好的理解。老师还能给学生自己的生动的经验。而通过这些告诉通讯工具来学习知识，是一种被动的过程，而且电视中更多的节目是迎合了人们追求感官享受，而很少能提供有益的知识。
161. "In this age of intensive media coverage, it is no longer possible for a society to regard any woman or man as a hero. The reputation of anyone who is subjected to media scrutiny will eventually be diminished."
109. "The purpose of many advertisements is to make consumers want to buy a product so that they will 'be like' the person in the ad. This practice is effective because it not only sells products but also helps people feel better about themselves."
107 "Instant communication systems encourage people to form hasty opinions and give quick replies rather than take the time to develop thoughtful, well-reasoned points of view."
215 "The bombardment of visual images in contemporary society has the effect of making people less able to focus clearly and extensively on a single issue over a long period of time."
