Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Children who watch violent television shows are at an increased risk of aggression and violent behavior. as they become young adults. That's based on a fifteen-year study published in the current issue of the research journal Developmental Psychology.
Back in the late 1970's when this study began, among the top rated shows were 'Chafiie's Angels' and 'The Six Million Dollar Man'. These were the TV shows that many of the 557 children in Raul Huseman's study were watching when they were six to ten years old. By today's standards these shows may not seem that violent, but there was a significant amount of on-screen physical violence in them. Huseman, from the University of Michigan, analyzed the types and amounts of violence in these shows and also collected other information on the kids about their home life, their friends, their school life, and importantly their levels of aggressive behavior, tike who was getting into fights, who was pushing and shoving (猛推) others, who was stealing things.
Now fast-forward 15 years: Raul Huseman was able to track down over 80% of the boys and girls from the original study. He re-interviewed them, now in their mid-twenties, and talked to their spouses (配偶) and close friends and checked their criminal records. "We found that those children back then, when they were 6, 7, 8 or 8, 9, 10, who had been watching more media violence had grown up to be more aggressive young adults as compared to the young adults who had been just as aggressive in childhood but had not watched as much violent television."
"Most at-risk children are children who watch a steady diet of violent television shows, identify with the aggressors, who sometimes the heroes and the lead-characters in those shows, and who perceive the violence as being realistic and a model for how to act in real life."
The conclusion of the fifteen-year study is that ______.
A．children born in the 1970s would display more violent behavior. than other children
B．children who like to push and shove others when fighting would develop violent behavior. quickly
C．young adults are the group of people who are most influenced by violent TV
