根据以下材料，回答题Laziness is a sin, everyone knows that.We have probably all had lectures pointing out that laziness is immoral, thatit is wasteful, and that lazy people will never amount to anything in life. Butlaziness can be more harmful than that, and it is often caused by more complexreasons than simple wish to avoid work. Some people who appear to be lazy aresuffering from much more serious problems. They may be so distrustful of theirfellow workers that they are unable to join in any group task for fear ofridicule or fear of having their ideas stolen. These people who seem lazy may beparalyzed by a fear of failure that prevents fruitful work. Or other sorts offantasies (幻想)may prevent work; some people are so busy planning, sometimes planning greatdeals or fantastic achievements that they are unable to deal with whatever"lesser" work is on hand. Still other people are not avoiding work;strictly speaking, they are merely procrastinating--rescheduling their day.Laziness can actually be helpful. Likeprocrastinators (拖延者), some people may look lazy when they are really thinking,planning, contemplating (沉思), researching. We shouldall remember that great scientific discoveries occurred by chance. Newtonwasn′t working in the orchard when the apple hit him and he devised the theoryof gravity. All of us would like to have someone "lazy" were causedby the worker′s taking time to check each step of his work and to do his jobright. And sometimes, being lazy that is, taking time off for a rest is goodfor the overworked students or executive.Taking a rest can be particularly helpful tothe athlete who is trying too hard or the doctor who′s simply working himselfovertime too many evenings at the clinic. So be careful when you are tempted tocall someone lazy. That person may be thinking, resting, and planning his orher next book.

根据以下材料，回答题Every day 25 million U.S. children fideschool buses. The safety record for these buses is much better than forpassenger cars; but nevertheless, about 10 children are killed each year ridingon large school buses, and nearly four times that number arc killed outsidebuses in the loading zones. By and large, however, the nation′s school childrenare transported to and from school safety.Even though the number of school buscasualties (伤亡事故) is not large, the safety of children is always of intense publicconcern. While everyone wants to see children transported safely, people aredivided about what needs to be done particularly whether seat belts should bemandatory (强制).Proponents of seat belts on schoolbuses--many of them parents and medical organizations argue that seat belts arcnecessary not only to reduce fatality and injury, but also to teach children lessonsabout the importance of using them routinely in any moving vehicle. A sidebenefit, they point out, is those seats belts help keep children in theirseats, away from the bus driver.Opponents of seat belt installation suggestthat children are already well protected by the school buses that adhere to theNation Highway Traffic Safety Administrations (NHTSA) safety requirements setin 1977. They also believe that many children won′t wear seat belts anyway andthat may damage the belts or use them as weapons to hurt other children.A new Research Council report on school bussafety suggests that there are alternate safety devices and procedures that maybe more effective and less expensive. For example, the study committeesuggested that raising seat backs four inches may have the same safetyeffectiveness as seat belts.The report sponsored by the Department ofTransportation at the request of Congress, reviews seat belts extensively whiletaking a broader look at safety in and around school buses. It may be inferred from this passagethat ______.查看材料

材料一：共享单车是指企业在校园、地铁站点、公交站点、居民区、商业区、公共服务区等提供自行车共享服务，是共享经济的新形态。截至2016年底，中国共享单车市场整体用户数量已达到1886万，预计2017年，共享单车市场用户规模将继续保持大幅增长，年底将达5000万用户规模。材料二：最近，各地有关共享单车“被虐”的消息不少。有的共享单车被“肢解”，零件缺失；有的被丢到河里、沟里；有的被人额外加了锁；有的车身被贴上“刻章办证”“信用卡套现”；有的二维码、编号被喷涂遮盖……有人说，共享单车是面“照妖镜”，照出了中国人丑陋的一面。公民的规则意识不足，“共享”理念尚未在人们心中扎根，正因如此，共享单车才在中国遭遇如此多的灾厄。材料三：共享单车是我国共享经济发展过程中的一个缩影，体现了我国在新时代背景下追求发展的新思维。我们都知道，每一个新想法，每一个新模式，最终要成为现实，都不可能是一蹴而就的。这其中或多或少会出现一些问题。而在此时，最重要的就是我们要齐心协力去寻找解决的途径与方法，这是对共享平台的要求，也是对公共监管的要求，更是对每一个参与其中、享受其中的人的要求。(1)请你运用经济生活的知识，分析共享单车行业迅速发展的积极意义。(4分)(2)结合材料和所学的哲学知识，分析在共享单车推广过程中出现种种乱象的原因，并说明我们应该如何应对。(4分)(3)请从政治生活的角度，为解决共享单车遭遇的问题提出对策建议。(10分)
