让别人分享财富

    ①十岁的时候,他和父亲推着板车去镇上卖西瓜,西瓜刚推到镇上,还没有卖出,天空中就阴云密布,要下雨了,过往的人们纷纷往回赶,再也没人来买西瓜了。他(沮丧  悲伤)得很,西瓜卖不出去了,还要推回去。

    ②这时,父亲说:“我们可以把瓜免费送人。”于是父亲带着他来到沿街的门市,一家给搬了两三个西瓜,人们纷纷用诧异的目光看着他们。父亲解释道:“要下雨了,                  。”有人说:“那你不是亏了吗?我拿钱给你。”父亲摆摆手说:“不用了,西瓜送给你们,我还赚个轻松,要是留着,推回去,明天不新鲜,又不好卖了。”那天,他们一无所获地回去了。可是后来,他们再来镇上,西瓜总是第一个卖完。因为他们那次送人家西瓜,人家记着他们的好,也因为父亲的话,大家也都相信他们的西瓜最新鲜。

    ③多年之后,他拥有了一家食品公司,他牢牢记得父亲当年卖西瓜的事。

    ④金融危机爆发了,经济形势十分严峻,他的工厂也被迫停产了,产品积压在仓库里卖不出去。他召集工人们开会,说:“现在工厂停产了,我把工资都结给你们,另外                  。”那些食品平日多是出口的,价格不菲。工人们乐得不行,大包小包地挑着带回家。剩下的食品,他又免费送给附近的居民,送给有业务没业务往来的多个商店和超市。

    ⑤后来,金融危机过去,市场(复活  复苏)了,他的公司订单多得出奇。当时好多厂都遭遇用工荒,而他的公司,工人们蜂拥而至,有老工人,也有慕名而来的新工人。因为他的免费赠送,让更多的人知道了他和他的公司。他_____立即恢复了生产,_____扩大了生产规模…

    ⑥生活中,我们在遇到危机时,不要死守着“财富”,让它们在手里慢慢变质,可以免费送给需要的人。免费和赚钱,从来就不是矛盾的。我们得学学那个老板,_____舍得让别人分享自己的“财富”, _____能赢得更好的未来。
