【简答题】
Televisions, stereos, telephones, and computers have changed the way we spend our time and what we know about the world. Some of the changes brought about by these material possessions have improved our way of life, but others have made it worse. Our young teenagers turn on the television, play the stereo, play games on the computer, talk on the telephone, and eat all the same time. This drives me right up the wall to instant insanity(精神失常). However, teens of today place too great an importance on material property. They spend an average of several hours a day watching television, listening to stereos, playing on the computer, playing video games, and talking on the telephone. Families no longer watch television together and there is great lack of communication. Materialism is evident when an otherwise intelligent teenager drives their parents crazy, and into debt, when misusing communication equipment. Teens judge and admire other teens for what they own and have, rather than for what they are or what they can do. They no longer care about values, like honesty, integrity(正直), freedom, talent, quality and other values and morals. However, good or bad, communication devices are here to stay. It is up to us, as parents, to stop our beloved teenagers from misusing and abusing our communication equipment and devices. We need to avoid the problems they present and to make the most of their opportunities they possess and hold for us all. 小题1:The writer’s attitude toward the modern material possessions is generally _____. A.positive B.negative C.neutral D.indifferent 小题2:According to the writer, teens’ overuse of communication equipment can do harm to _____. A.their own health B.their own study C.their own morality D.their neighbors’ life 小题3:The writer attributes (归咎) the unsatisfactory behavior of teens to _____. A.teens’ too much free time B.parents’ non-interference C.inadequate school education D.material property 小题4:It can be inferred from the passage that the writer seems to be most annoyed at ______. A.all the modern material possession B.eating while talking on the phone C.the decline in teens’ morality D.all the communication equipment
