冰冷的江水中，10多名大学生手拉手搭成“人梯”，将两名落水少年拉向生的此岸，3名大学生却终被无情的江水卷走……2009年10月24日，在湖北省荆州市的长江边，上演了如此感人、如此惊心动魄的一幕。10月26日，荆州市授予在长江荆州宝塔河段救起两名落水少年的17名大学生和市民“舍己为人见义勇为英雄群体”。这17人当中包括14名长江大学的学生和3名沙市冬泳队的老人。2009年11月12日上午，10月24日长江救人英雄集体先进事迹首场报告会在湖北荆州市委礼堂举办，来自荆州市的机关干部、在校大学生、武警官兵、医护人员、普通市民等四百多名代表，聆听了英雄事迹报告。
材料2
10月24日，长江大学3名大学生何东旭、方招、陈及时为救两名落水少年，献出了宝贵的生命。令人心寒的是，在打捞英雄遗体时，面对同学们的“跪求”，个体打捞者不仅不为所动，而且挟尸要价，一共收取了3.6万元的捞尸费。11月7日，荆州市人民政府召开新闻发布会，向社会通报打捞3名大学生英雄遗体全过程。结果显示，10月24日在打捞3名大学生英雄遗体过程中，现场收取3.6万元费用的打捞公司业务负责人陈波，因额外向学校索要烟和矿泉水“构成了敲诈勒索”，公安机关已依法将其拘留15天，罚款1000元。

Solving a problem can be broken down into several steps. First, the problem must be identified correctly. Psychologists refer (1) this step as problem representation. For many problems, figuring (2) which information is relevant and (3) is extraneous can be difficult and can interfere (4) arriving at a good solution. Clearly, before a problem can be solved, it must be obvious (5) the problem is, however, this is not as easy (6) it might seem. One obstacle to efficient problem representation is functional fixedness, that is, allowing preconceived notions and even prejudices (7) color the facts. Most people tend (8) see objects and events in certain fixed ways, and by being inflexible in viewing the problem, they may be unable to notice the tools (9) the solution. Once the problem is identified accurately, (10) , the second step consists (11) considering the alternatives for a solution. A common way to evaluate alternatives is to write them (12) and then make a list (13) advantages and disadvantages for each solution. Here again, people may be limited by prior experiences. Often people adopt mental sets (14) lead them to the same problem-solving strategies that were successful for problems (15) the past. Although that can be helpful most (16) the time, sometimes a new situation requires a different strategy. (17) that case, the mental set must be abandoned, (18) new alternatives must be explored.
After the alternatives have been compared, a strategy must be selected (19) among them. One way to avoid becoming mired in the options is (20) try the best option with a view to abandoning it for another (21) the results are unfavorable. This attitude allows many people to move on expeditiously (22) the next step—action. The strategy selected must be implemented and tested. If it solves the problem, no further action is necessary, but if (23) , then the cycle begins again, starting (24) problem identification. By continuing to review the problem (25) repeat the problem-solving steps, the solution can be improved upon and refined.
