Unit 4 Astronomy the science of the stars李仕才【閱讀理解插花】The more hours young children spend in child care, the more likely they are to turn out aggressive and disobedient by the time they are in kindergarten, according to the largest study of child care and development ever conducted. Researchers said this correlation(相關(guān)性) held true regardless of whether the children came from rich or poor homes, were looked after by a relative or at a center, and whether they were girls or boys. What is uncertain, however, is whether the child care actually causes the problem or whether children likely to turn out aggressive happen to be those who spend more hours in child care. It also remains unclear whether reducing the amount of time in child care will reduce the risk that a child will turn into a mean person. Whats more, quality child care is associated with increased skills in intellectual ability such as language and memory, leading some academics to suggest that child care turns out children who are “smart and naughty”. The government-sponsored research, which has tracked more than 1, 300 children at 10 sites across the country since 1991, is bound to cause the debate over child care again: How should people balance work and family? And how should parents, especially mothers, resolve the demands that are placed on them to be both breadwinners and supermoms? That debate was already on display at a new briefing yesterday, where researchers themselves had different opinions about the data and its implications(含義). “There is a constant relationship between time in child care and problem behavior, especially those involving aggression, ” said Jay Belsky of Birkbeck College in London, one of the lead investigators of the study who has previously annoyed womens groups because of his criticisms of child care. “On behalf of fathers or mothers? ” interrupted Sarah Friedman, a developmental psychologist at the National Institute of Child Health and Human Development (NICHD) and one of the other lead scientists on the study. “On behalf of parents and families, ” responded Belsky. “NICHD is not willing to get into policy recommendations, ” said Friedman, contradicting her colleague. “There are other possibilities that can be entertained. Yes it is a quick solutionmore hours in child care is associated with more problems. The easy solution is to cut the number of hours but that may have implications for the family that may not be beneficial for the development of the children in terms of economics. ” In an interview after the briefing, Friedman said that asking parents to work fewer hours and spend more time with their children usually meant a loss of family income, which adversely(不利地)affects children. Scientists said that the study was highly reliable. But the researchers said they had no idea whether the behavioral difficulties persisted as the children moved to higher grades. 【文章大意】本文講述兒童早期在托管所的成長對孩子的心理有負(fù)面影響。1.
