2016年12月25日圣诞节到来之际，国内许多超市和水果店的苹果傍上平安夜化身“平安果”，销量大增，平时2元/个的苹果价格涨到10元/个。下列对苹果在平安夜价格大幅上涨的原因分析正确的有①苹果的生产成本大幅提高 ②市场上的供求状况发生了变化 ③苹果的使用价值增加是决定性因素 ④商家借机炒作以谋取利润A. ①② B. ②④ C. ①③ D. ③④Greg Woodburn, a student at the University of Southern California, spends a lot of time cleaning sneakers he collected. But soon the shoes will be sent to poor children in the United States and 20 other countries, thanks to Woodburn’s Share our soles (S.O.S) charity.A high school track star in the town of Ventura, California, Woodburn was treated in hospital for months with foot injuries.“I started thinking about the health benefits, the friendship and the confidence I got from running,” he says, “And I realized there are children who don’t even have shoes”.Woodburn gathered up his old sneakers, and then asked his friends to donate. His goal was to have 100 pairs by Christmas 2006. When he collected more than 500 pairs, he decided to turn the shoe drive into a year-round effort.Back then, the sneakers came from donation boxes and the local sporting goods store and from door-to-door pickups. Woodburn has now set up collection boxes at two high schools, city gym and recreation center. So far, S.O.S has collected and donated more than 3,000 pairs.Woodburn has cleaned all the shoes. After sorting the shoes by size, Woodburn selects the good shoes for the washing machine and the worn-out ones for recycling.For many recipients, the shoes represent opportunity. Two young boys in Southern California attended school every other day because they shared a pair of shoes. They were too big for one boy and too small for the other. Thanks to S.O.S, each brother received his own pair of shoes. The boys now attend school daily and enjoy their learning.
