In her book No Exit: What Parents Owe Their Children and What Society Owes Parents, she argues that parents are burdened in many ways in their lives: there is “no exit” when it comes to children. “Society expectsand needsparents to provide their children with continuity of care, meaning the intensive, intimate care that human beings need to develop their intellectual, emotional, and moral capabilities. And society expectsand needsparents to persist in their role for 18 years, or longer if needed.”What is Professor Anne Alstotts argument for parental support? A、Good parenting benefits society. B、The cost of raising children in the US has been growing. C、The US should keep up with other developed countries. D、Children need continuous care.【正确答案】A【答案解析】答案选 A。推理判断题。本段提到，社会也需要家长们对他们的孩子付出关爱，因为良好的父母教养能造福于社会，应选A项。B项“抚养孩子的成本在美国已越来越大”，C项“美国应该赶上其他发达国家”，这两项在文中均未提及；D项“儿童需要持续的照顾”，是对文中的parents to provide their children with continuity of care设置的干扰项。第8题【单选题】Sarah hopes to become a friend of _ shares her interests.
