[单选题]请阅读短文，完成此题。 Back in the old days, when I was a child, we sat around the family round table at dinnertime and exchanged our daily experiences. It wasn't very organized, but everyone was recognized and all the news that had to be told was told by each family member. We listened to each other and the interest was not put-on; it was real. Our family was a unit and we supported each other, and nurtured each other, and liked each other, and--we were even willing to admit--we loved each other. Today, the family round table has moved to the local fast-food restaurant and talk is not easy, much less encouraged. Grandma, who used to live upstairs, is now the voice on long distance, and the working parents far too beaten down each day to spend evening relaxation time listening to the sandbox experience of an eager four-year-old. So family conversation is as extinct as my old toys and parental questions such as "What have you been doing, Bobby?" have been replaced by "I'm busy, go watch television. "And watch TV they do; count them by the millions. But it's usually not children's television that children watch. Saturday morning, the children's hour, amounts to only about 8 percent of their weekly viewing. Where are they to be found? Watching adult television, of course, from the Match Game in the morning, to the afternoon at General Hospital, from the muggings and battles on the evening news right through the family hour and past into Star sky and Hutch. That's where you find our kids, over five million of them, at 10 p.m., not fewer than a million until after midnight! All of this is done with parental permission. Television, used well, can provide enriching experiences for our young people, but we must use it with some sense. When the carpet is clean, we turn off the vacuum cleaner. When the dishes are clean, the dishwasher turns itself off. Not so the television, which is on from the sun in the morning to the moon at night and beyond! Parents must exercise some control and show some concern about the cultural influence on the child when a program not intended for that child is viewed. Parents need to intervene. Nonintervention may be a wise policy in international affairs, but the results of parental nonintervention will not be wise at all. What is the main idea of the last paragraph? 查看材料
A.Parental nonintervention will not be praised.
B.Nonintervention may be a good policy in international affairs.
C.Parents must exercise some control and show some concern about the cultural influence on the children.
D.Parents need to intervene.
