什么叫“液击”？它有什么危害？

（19分）雷锋，离开我们已经整整50年了。半个世纪以来，雷锋这个响亮的名字和以他的名字命名的雷锋精神，深深镌刻在一代又一代中国人的心中，影响和激励着一代又一代人的成长。值此毛 * * * * 题词“向雷锋同志学习”49周年之际，国内外媒体热炒“雷锋精神”。某中学高三（1）班的学生对此颇感兴趣，成立自主学习小组，围绕“雷锋精神伴我们成长”的主题进行探究，请你一并参与其中。

第一小组的同学了解到，雷锋出生在旧社会一个穷苦农民家庭，7岁沦为孤儿，然而他没有在逆境中沉沦。解放后，他先后加入少先队、共青团，并成为一名军人和 * * 党员。他从事的是拖拉机手、推土机手、汽车驾驶员等普通而平凡的工作，但他干一行、爱一行、钻一行，在平凡的岗位上做出了不平凡的业绩。他“把有限的生命投入到无限的为人民服务之中去”，省吃俭用捐助受灾群众；利用休息时间到车站扶老携幼；出差时，为旅客端茶送水，打扫卫生，他从一点一滴小事做起，但做了好事却从不留姓名。1962年，22岁的雷锋在执行运输任务时不幸殉职。

(1)该班学生探究的主题蕴含的唯物论道理是什么？(3分)

(2)材料中雷锋的成长足迹对你有何辩证法启示？（12分）

第二小组的同学在探究中发现了一件有趣的事，在时尚嗅觉敏锐的年轻人中间，一股“雷锋热”又悄然兴起：雷锋帽、大茶缸子、帆布绿背包，这些曾一度被封上“老土”标签的玩意如今又刮出了时尚风，由于供不应求，几家大型电子网购网站甚至打出了“雷锋帽”售罄字样。这一现象引起了同学们的议论。

甲同学说：“雷锋精神的实质是奉献，学习雷锋不应单纯着眼于经济利益”。

乙同学说：“现在是市场经济，利用雷锋的影响力获取经济利益无可厚非”。
