第9题

Some individuals and citizens' groups have expressed concern about the level of viol

ence in television programs, particularly in action-adventure series and cartoons.They argue that viewers, especially children, may learn to see violence as the only way to resolve conflicts.

Early experimental researchers compared the play of children who had seen aggressive behavior. on television with the play of a control group of children who had watched nonviolent programs.Concern was intensified by findings that indicated a higher level of aggressive play in the violent-television group.Other researchers attempted to determine whether violent programs simply stimulated higher energy levels in children or actually caused them to learn violent and antisocial behavior.The results of different studies conflicted.Some researchers claimed that televised violence actually had a positive cathartic effect, allowing some viewers to release heightening tensions; these findings, however, were not confirmed in further studies.Other scholars pointed out that both prosocial and antisocial behavior. can be learned from television.

Social scientists find it especially difficult to assess accurately the subtle, cumulative effects of viewing a broad variety of television programs throughout childhood.Distinguishing the possible effects of television from other influences at home and at school is also difficult.Current research suggests that moderately higher levels of anti-social behavior. can be traced to television viewing, but further study needs to be done to confirm it.

Because of the long-standing tradition in the U.S.of freedom of speech and of the press, the government would probably not attempt to directly limit or censor the appearance of violence of television.Among the networks and producers, pressure from concerned citizens continues to be balanced by the increasing popularity of high-energy action-adventure programs.

1.What is the passage mainly about？

A.Violence in television programs.

B.Levels of violence in action-adventure series and cartoons.

C.Educational programs for children.

D.Researches on television programs.

2.Those researchers who believe violence on TV has a positive effect on viewers think that （）.

A.it teaches people not to use violence to resolve conflicts

3.A “prosocial” behavior. is one （）.

A.that is against the social norm

B.that meets the expectation of the society

C.that a child shows in communication with people

D.that can often be shaped by TV programs

4.Which of the following statements is TRUE according to the passage？

A.Television viewing leads naturally to antisocial behavior.

B.Violence on television does not help shape violent behavior. in children.

C.The effect of violent TV programs on children needs further study.

Educational attainment in rural America reached a historic

height in 2000, with nearly one in six rural adults holding a 【M1】______

4-year college degree, and more than three in four complete 【M2】______

high school. As the demand of workers with higher educational 【M3】______

qualifications rises, many rural policymakers

have come to view local educational levels as a critical

determinant of job and income growth in their communities.

But policymakers are facing with two key questions. 【M4】______

First, does a better educated population lead to greater

economic growth？ According to a recent study, rural counties

with higher educational levels saw rapid earnings and 【M5】______

income growth over the past two decades than counties with

lower educational levels. However, economic returns to

education for rural areas continue to lag that for urban areas. 【M6】______

Second, are there Ways to improve local educational attainment,

particularly through improvements in elementary and high

schools, It can enhance the economic well-being of rural 【M7】______

residents and communities？ In fact, preliminary research

demonstrates a connection between better schools and positive

outcomes in terms of earnings and Income growth for rural

workers and rural communities.

Ultimately, the strength of the tie between education and

economic outcomes is influenced in part by the extent which 【M8】______

small rural counties lose young adults through

outmigration. The loss of potential workers from rural areas, as

young adults leave college and work opportunities in urban 【M9】______

areas, has concerned rural observers for many decades. This

rural "brain drain" not only deprives rural employers of an

education workforce, but also depletes local resources because 【M10】______

communities that have invested in these workers' education

reap little return on that investment.

【M1】
