2．The more hours that 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．What's 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 1，300children at 10sites 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 care and problem behavior，especially those involving aggression and behavior，"said Jay Belsky of Birkbeck College in London．one of the lead investigators of the study who has previously annoyed women's 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．Yesit is a quick solution-more 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，F(xiàn)riedman 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．

分析 本文是一篇科教類閱讀，屬于議論文，根據(jù)兒童保育和開發(fā)機構進行的研究，花更多的時間照顧的孩子，他們就越有可能變得咄咄逼人，不聽話在幼兒園．本文以此展開，主要講述了照顧孩子的時間對孩子的影響．
解答 32．答案：A．細節(jié)理解題．根據(jù)The more hours that 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．可知，花更多的時間在照顧孩子上，孩子將開發(fā)更大的語言能力．故選A．
33．答案：C．細節(jié)理解題．根據(jù)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．可知，照顧孩子實際上是否會導致問題還是那些花更多時間在照顧孩子上孩子可能會變得咄咄逼人．故C項是否長期照顧是導致孩子咄咄逼人的直接原因符合文章內(nèi)容．故選C．
34．答案：C．詞義猜測題．根據(jù)該句之后的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可知，it指代的是照顧孩子的時間應該大幅減少．故選C．
35．答案：A．細節(jié)理解題．根據(jù)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．可知，減少照顧孩子的時間可能阻止家庭擁有必要的金融資源．故選A．
點評 本文是一篇科教類閱讀，題目涉及多道細節(jié)理解題，詞義猜測題．做題時學生應仔細閱讀原文，把握文章主要內(nèi)容，聯(lián)系文章上下文內(nèi)容并結合所給選項含義，從中選出正確答案，一定要做到有理有據(jù)，切忌胡亂猜測．
