Once we learn the rules for map reading, they seem so simple: up is north, blue is water, a star stands for a capital. But when and how do we learn to read a map? Research shows that even three-year-olds can master, at least in a basic way, the key map-reading concept(概念): a map is a two-dimensional symbol(二维的符号)for three-dimensional space. Linda Acredolo of the University of California, showed a child a map of a room pointed out on it where a toy was hidden and asked the child to find that toy. Depending on the maps orientation(方位), about half the three-year-olds could successfully do so. Three years may be the age at which the ideas become fully understood. Judy Deloache of the University of Illinois let children watch her hide a small toy in a scale model of a room and asked them to find a large one in a real room. "A three-year-olds can do it, but a two-year-olds has no idea that the model has to do with anything larger, " she says. But even if the basic concept is there early, Lynn Liben and Roger Downs of Pennsylvania State University found that children still have a lot to learn. Second graders believe that north is always at the top of a map because of the hanging maps they have seen. "If you asked them to close their eyes and point in the direction of north, often theyll point straight up," says Lihen. She says that children get map-reading skills gradually, and teachers must begin by using maps of familiar areas: their own classrooms, homes, and neighbourhoods.The first two experiments show that______.A．children have better understanding than grown-upsB．children have special natural ability for map readingC．children are more interested in toys than in mapsD．children can start to learn map-reading early

苏某系某市制药厂的职工，受该厂委托去某限价区内收购当地农民采挖的麻黄草，收购后苏某雇了个体运输户陈某的汽车，将麻黄草运往所属的制药厂。在运输途中，被该县草原监理所工作人员发现，经检查，苏某、陈某并未持有采药许可证及调运、货运的合法批准手续，该县草原监理所遂对苏某作出没收麻黄草并处以麻黄草价款2倍的罚款处罚。在执法过程中，该监理所工作人员认为苏某认错态度不好，对其进行了殴打。苏某不服，提起行政诉讼，要求撤销该行政处罚决定、确认该监理所工作人员的行为违法并对其所造成的人身伤害给予赔偿。在诉讼过程中，苏某提出县草原监理所处罚对象错误，他受市制药厂的委托，不应对其进行行政处罚。被告遂向法院申请补充收集与此相关的证据。法院应否准许？（）
