The new teen wave is richer, better educated and healthier than any other in history, in many ways, these teens are uniquely privileged. Cable and the Internet have given them access to an almost infinite amount of information. Most expect to go to college, and girls, in particular, have unprecedented opportunities; they can dream of careers in everything from professional sports to politics, with many women's role models to follow.
But this positive image of modern teens is a little like yearbook photos that depict every kid as happy and ideal. In survey after survey, many kids say they feel very lonely, unable to connect with their parents, teachers and sometimes even classmates. They're desperate for guidance, and when they don't get what they need at home or in school, they join groups or create their own universe out of their parents' reach, a world defined by computer games, TV and movies. Sociologist Barbara Schneider from University of Chicago has been studying 7,000 teenagers for five years and has found they spend an average of 3 and 1/2 hours alone every day. Teenagers may claim they want privacy, but they also need attention — and they don't always get it. Even the most caring parents can't protect their kids from teenage problems, but involved parents can make an enormous difference — kids do listen.
1) Why are the new teens uniquely privileged?
A) The new generation is more intelligent.
˅B) The new generation has more opportunities.
C) The new generation works more.
D) The new generation can use a computer. :.
2) What is a major problem of modern kids?
A) Too much information. C) Lack of computer games.
B) Loneliness. D) Teacher's guidance.
3) What do children who don't get attention at home do?
A) They try to talk to parents.
B) They misbehave.
C) They join groups or create their own world.
D) They escape from home.
4) What do teenagers really need?
A) Privacy. C) Attention.
B) A TV and computer. D) Confidentiality.
