You want to know where the safest place for young children is in the car? Experts all say the back seat is the safest place for a child of any age. In the back seat, the child is farthest away from the force or effect of a head-on collision (迎头撞击) , which can cause the most injuries. Just as important, the child in the back seat is removed from the passenger airbag, if there is any. If your child is under eight years of age and weighs more than 80 pounds, it is necessary to fit your car with a special child-safety seat. The child-safety seat comes in three types or sizes: The first type is designed for babies from birth to one year of age, until the baby weighs about 20 pounds; the second size is for children between one and four years of age, who weigh between 20 and 40 pounds; the third kind is used by older children big enough to use the car's belt system. Moreover, all these safety seats must be fitted and held in place on the car's back seat. If your child does need your attention while. you are driving, don't look back with only one hand on the wheel. Just pull over.

【正确答案】
B
【答案解析】[精解] 细节题。题干意为“第三种型号的安全座椅是为哪些孩子准备的?”文章第一段的最后一句说If your child is under eight years of age and weighs more than 80 pounds, it is necessary to fit your car with a special child-safety seat．即对于小于8岁的孩子有安装安全座椅的必要。又根据文章第二段的the third kind is used by older children big enough go use the car's belt sys- tem．这里的older是和前一句中的one and four years of age来比较的，所以第三种型号的座椅是为那些大于4岁却小于8岁的孩子们准备的。所以本题的正确答案为B。
