1. D细节理解题。由题目中的关键同over 700 children in Redondo Beach. California,可回原文定位于第三段。根据"The students do this once a week."可知，他们每周步行去上学一次，因此D项表述"他们和父母每天步行去上学"是错误的。根据第三段最后一句"It also means to increase their activity,or fitness levels."可知，步行去上学意味着改善健康，排除A;根据第三段第一句"...walking to school with parents and,in some cases,even their dogs."可知，他们和父母或狗一起去上学，排除B;根据第四段"It's a good way to make the kids exercise in the morning."可知,步行去上学是让孩子锻炼的好方法，排除C。
