| Regular child care provided outside
home or by someone other than the mother does not in itself undermine healthy
emotional connections between mothers and their 15-month-old infants, according
to a long-term national study. The finding holds even if care begins during the
first 3 months after birth and runs for 30 hours or more per week. Among infants who receive unkind and unresponsive care from their mothers, however, the mother-child relationship may be damaged. "This research helps us put apart complexities regarding child care that have not previously been studied in detail," contends Jay Belsky, a psychologist. The investigation consists of 1,153 children and their families living in or near Boston. The youngsters, no more than 1 month old when they entered the study in 1991, will be tracked until the age of 7. Experimenters administered que A. rain a kid’s growth B. harm the mother-child tie C. injure a baby’s emotional reaction D. spoil a child’s personality [单项选择]思想品德教育过程中，如果只看到学生差的地方，认为无可救药，那就违背了（）原则。

A. A组和B组受试者在心里素质方面有很大差异吗？ B. B组受试者是被授意说假话，而不是自己要说假话，由此得出的说假话与眨眼之间的关联可靠吗？ C. 用于A组和B组的仪器设备是否有什么异常？ D. 说假话是否会导致心跳加速，血压升高？ [填空题]不合格产品包括（）品和（）品。
