| The media can impact current events. As
a graduate student at Berkeley in the 1960s, I remember experiencing the events
related to the People’s Park that were occurring on campus. Some of these events
were given national media coverage in the press and on TV. I found it
interesting to compare my impressions of what was going on with perceptions
obtained from the news media. I could begin to see events of that time feed on
news coverage. This also provided me with some healthy insights into the
distinctions between these realities. Electronic media are having a greater impact on the people’s lives every day. People gather more and more of their impressions from representations. Television and telephone communications are linking people to a global village, or what one writer calls the electronic city. Consider the informa A. the 1992 Los Angeles riots lasted a whole week B. Rodney King seemed very angry when he appeared on television on Friday C. media coverage of events as they occur can have either good or bad results D. most people who had seen the video of Rodney King beating agree with the verdict [简答题]资本主义为什么必然爆发经济危机？
