<title><![CDATA[多做点有用事]]></title>
<link>http://tgzxs4.eduol.cn/archives/2008/704680.html</link>
<description><![CDATA[多年来，经历的事不少，感触颇深。感人的事往往稍纵即逝，而那些不为心动的事却挥之不去，像一块沉重的巨石压得透不过气来。<BR>性情中人，情绪总是容易激动。哪怕一些小事，都会让情绪昂扬。对生活中的某些做法难以接受，甚至牢骚满腹。这些事并没有多大害处，但不见得有何益处。最讨厌的就是折腾，循环往复，周而复始，不厌其烦。工作的人都知道，计划、总结之类年年写、月月写、天天写，总是写不完。那种千篇一律，敷衍了事的稿子有什么用呢？哪个人不是假、大、空的胡乱一通，自我炫耀，自我表功。有几个是说真话，真的解剖自己、反省自我？你说，这样的内容，没有更好，有，反而让人不舒服。<BR>中国有句古话，活到老，学到老。这非常好，对我们来说，时时充电，可以丰富自我，完善自我。记得外国人到中国工作，不长时间，都要申请回国学习，恐怕知识陈旧，被社会淘汰。那是主动要求深造，完善自我。而我们，总是被牵着鼻子走。什么什么培训，某某某学习，都是瞎扯淡，掩人耳目。培训了，学习了，学到什么没有。我想，只有经历的人，自己才能说出钉铆。那种形式的教育，耗费的物力、财力、精力。若是没有好的身体或者忍耐的态度是经受不住煎熬的。有人说，外出学习，就是度假，是减压，也许有道理。假培训、假考试当然不费吹灰之力，人人乐而笑之。<BR>平时，每年都要进行各种考试，那简直是小儿科，形同虚设，根本没有起到任何指导和提高的作用。试卷发下，连同“标准”答案。只要依葫芦画瓢就行了，可以请他人代抄，可以抄一些、丢一些，可以灵活处理。最幸运的还是领导，从来都有人代替，自己还不知是啥回事。你说，这样的考试，恐怕就是中国特色吧！我看，简直是作孽。这种把戏，早把老百姓玩腻了。<BR>从小就听人说，国民党的税，共产党的会。那时还不甚明白，如今知道这话不假。我就不明白，为什么我们的会如此之多？天天开，时时开，没完没了。有些会必不可少，有些会可开可不开的，就不要开，是不是我们的时间太多，闲得乏味，才开会打发。要知道，很多会，很多人，都是不情愿的。你看，就连改革开放30年的庆功会，都有一部分同志昏昏睡焉。这说明，会，实在无聊；会，实在太长；会，实在太多，让同志们吃不消了。我想，如果把一些没用的会取消，用来做一些对老百姓有用的实事，老百姓欢迎，自己心里塌实、爽快，何乐而不为？如果会上的发言能够短小精悍，传达旨意即可。就可以节省很多时间去做一些实事，那有什么不好？何必要拖泥带水，拖沓冗长。一定要按样式：一、二、三……甲乙丙罗列。何必在会上显耀自己的三寸不烂口舌？借以显示自己的身份地位的不一般。也有这样的会，望而生畏，令人生厌。那就是缺乏教养的领导乱放空炮，把他娘捆到台上作为挡箭牌，这些同志，也包括教育工作者在内。你说，只会整天骂娘的领导干部，有几分成色？<BR>当然，许多同志知道这个时代，人们喜欢新奇事物。他们适应能力非常快。既然喜欢新鲜，我就跟你玩深沉，所以，变着花样，跟同志们玩猫戏老鼠的把戏。老百姓折腾得累了，麻木了，也就不会“叫嚣”，这样，社会也就安定了。也有小部分，想张扬个性，时间一久，也消磨沉寂了。中国人就是这个样，乐于做好好先生，喜欢折腾，慢慢混时光。<BR>我就不理解，为什么一代又一代的中国人，都有充裕的时间玩花样，而做有用的事的时间没有？也许是道家思想作祟吧？往事一幕一幕从眼前逝去，再也无法抓住，未来的时日还很长。提着沉重的笔，满腔热血，我希望每一个有良心的人，应该在有限时日做出有用的事，不要碌碌而为，不要瞎折腾！]]></description>

<description><![CDATA[叮当响处，驯鹿载着那个驾着卡通车子的穿戴着独一无二服装的白胡子老爹来到人间，本来他只光顾西方世界，不知从哪天起，他也兴致勃勃地来到了中国，这片古老的土地上的孩子，越来越熟悉这个老爹，每年的这个时刻，他们都会盼着他爬进自家的烟囱，悄悄给他的枕边送上自己早就心仪的礼物。虽然他们不知道为什么要送礼物，<NOBR oncontextmenu="return false" onmousemove=kwM(0) id=clickeyekey0 onmouseover="kwE(event,0, this)" style="COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick='kwC(event,0,"")' onmouseout=kwL(event,this)>圣诞</NOBR>的宗教意味他们也不关心，他们只关心能有个快乐的理由，能有个得到礼物的借口。</CLK><BR>商家是最精明的，他们不可能错过这样的商机，连什么感恩节、情人节、父亲母亲节。都引进，这样重大的节日怎么可能不做文章？虽然不能考证是什么人引进了圣诞节，但可以肯定是商家渲染了圣诞节，诱人的打折讯息掏走了多少主妇兜里的钞票！<BR>年轻人是最爱热闹的，春节恰逢了假期，各回各家，走亲访友，想聚都难，圣诞正好是个聚会的理由，呼朋引伴，三五成群，通宵狂欢，彻夜不眠，尽情释放心中的青春激情，哪管它什么《圣经》“耶稣”的神圣使命！<BR>手机时代，信息高速公路，朋友之间难得聚会，想问候时，找准节日的时机，发个短信，提个醒，表明一下自己的存在，表达一下对朋友的关心，圣诞节的意义也就成了短信问候的绝佳时机，一句“圣诞快乐！”带去多少温馨的关怀！<BR>住在这个地球村里，文化的互相渗透只是一夜之间的事，可谓“忽如一夜春风来，千树万树梨花开”，曾经闭关锁国，以天朝大国自居的封建王朝已经远去，现代的中华大地，早已是兼容并举，百花齐放，各种文化，各种文明都在这片土地找到了生存的空间，得以生根长叶。中国人的宽容，开放的胸襟，接纳，包容的肚量，是哪个民族也难以企及的。<BR>“有容乃大”，应该有海纳百川的气度，只是，我们还必须让我们的孩子知道，什么是我们的根，我们文化的根，如果有一天，他们把圣诞节过隆重了，却忘了过春节；如果有一天，他们把春节过成了圣诞节，那我们的民族就该呜咽悲戚了。诚如现在，许多婚礼的仪式完全西化，黑眼睛黑头发黄皮肤的中国新人们，也披上了洁白的婚纱，或者是不伦不类穿上红红的婚纱，走在猩红的地毯上，在西式仪式中，完成了自己一生中最神圣的时刻。连农村都开始效仿，追求这所谓的时髦，没有人知道，为什么要这样做，只是流行的前沿怎样，大众就怎样，只知其然，不知其所以然。<BR>我们不能故步自封，惟我独尊，但我们也决不能崇洋媚外，外国的月亮并不比我们的圆，我们是同一颗星球上的臣民，是同样的太阳普照，同样的月亮浸润下的人，我们和他们可以和谐相处，但我们更应该有我们的特色，世界只有文化各异了，才能多姿多彩]]></description>

<description><![CDATA[活着，真累!做人，真难!<BR>以前我一直会说“活着，真好!”现在我只想说做人真难。<BR>生活，我们得学会做人，学会听家长的话，学会孝敬父母，尊老爱幼，学会和周围的人和平相处，学会能忍则忍。可是很多时候为什么没人尊重我们，大人总把我们当小孩，“大人说话，小孩插什么嘴。”多么经典的一句台词。没人体会我们只能被动的接受你们所说的一切是否有什么不悦。很多时候在我们看来我们所做的只是一个内心的真实想法，然而却被戴上“忤逆”的头盔，成为大不孝之人，辱没祖先名声。我们还能怎样，为了对得起所谓的祖先，为了爸妈生了个乖小孩，我们也只能说"爸妈，我做错了，下次在也不会发生这种事了。”从今以后，我们是乖小孩，父母看了不会再是愁眉不展，说不定还是心花怒放。亲朋好友还会称赞真懂事。<BR>其实有时候那样也是挺不错的，好话人人都爱听，可是那样的话不就埋没了自己，每天压抑着情感过日子，那现在和皇权专政的时代有什么不同，还要什么21世纪的青年呢。<BR>父母老师不允许早恋，然而当他们的子女出现这种情况时，那些孩子变成了坏人，十恶不赦，每天都活在爸妈的强迫，老师的教育，同学的议论纷纷下生活，能不累吗。虽然这事在我身上发生过，只是每每在同学眼中看这疲惫，我也只能跟他们说放弃吧，早恋对我们来说不好，我真的不知道自己还能做身么。然而说实话如果可以的话我不希望是这样的结局。我不觉得这会有什么大不了的，以前那么大的孩子不早已成为人妻吗，也许会有人说，时代不同了，那是以前。是啊，时代不同了，那你现在还不是照样吃饭睡觉。能有什么，我知道父母是为了我们好，可是不是所有的观点都能从你们那里继承过来，我们的生活应该由我们来探测，自己领会的才会深刻。只要不会有什么意外就行。父母可以跟我们好好谈，而不是你们说什么就得是什么。;那样我们真的累。<BR>很多时候我们的所做所为换来的只是别人在背后的指指点点，乱嚼舌根。然而我们不一定是错，只是在你们看来是一场好戏。很多的人不愿理会世俗的压力，于是只有高呼不知道是哪位伟人说的“走自己的路让别人说去吧！”可是我想就是着位为人也没可能尽做的到。真正有几个人可以做到如此清高。在别人把你从上到下，从下到上，把你祖宗都扯了一遍，“三人成虎”你还能若无其事，继续走自己的路，在你身边的都是世俗的目光啊，我们如何心无旁骛。至少我做不到。人不能离开社会，我们也不能“无视”别人的存在，潇洒的说：“走自己的路让别人说去吧！”看看整个现实，我们也只能叹心有余而力不足。要想生存就得随波逐流，毕竟我们都不会想被当成另类。现在还是会有很多人不承认中国公产党的所做所为，然而还不得是应了那句老话“人在屋檐下，不得不低头。”为了生存，也只能将其隐藏，既然这样下去根本就不会如自己所愿，又何必执迷不悟，还不如做个乖小孩，那样父母会开心，也算尽了孝道。<BR>]]></description>

<title><![CDATA[君子爱财，取之有道]]></title>
<link>http://tgzxs4.eduol.cn/archives/2008/701061.html</link>
<description><![CDATA[“古来芳饵下，谁是不吞钩？”贪婪的心术，驱使着馋嘴者垂涎欲滴地去吞吃钓钩上馥郁的“芳饵”。但当吞下“芳饵”的同时，无可奈何地连锋利的钢钩也吞进了嘴里，钩尖狠狠地刺进了口腔，想吐再也吐不出来了。因而又有劝诫诗曰：“利旁有倚刀，贪人还自贼。”尽管如此，官场上还总难免有一些欲壑难填的贪吏，不惜冒着生命之险去贪食“芳饵”，徇私枉法，黑手取白银，结果自断前程。纵然有的贪官能侥幸暂时得到非分之财，但是花着和存放着的时候，心里总觉着不踏实，甚至是惶惶不可终日而忧累万千。因为自知非法钱财之来源，已经种下了犯事的祸根，心底就永远潜伏着一种如痨似癌的隐患。所以，诚实的人和有修养的人，绝对不敢伸手拿取非分之钱财。<BR>　　东汉太守杨震，部下故人夜怀十金来行贿，被他严辞拒绝。部下故人却说：“暮夜无人知晓。”杨震说：“天知、神知、我知、子知，何谓无知？”这就是史称拒贿名言：“杨震四知”。常言道“没有不透风的墙”“纸里包不住火”、“要想人不知，除非己不为”。尤其是肮脏的“权钱交易”之后，行贿之辈必然肆无忌惮地去违法谋利而彰显恶行，还自认为“无人知晓”。其实，这只不过是贪贿之徒掩耳盗铃，自欺欺人而已。法网恢恢，疏而不漏，不法之人终将难逃法律的制裁。<BR>　　现在我国在资本转型时期，就出现了形形色色的各类贪官。随着反腐斗争的不断深入，一些不法官员纷纷落马。纵观他们堕落的深层原因，无一不是贪婪之心太重所致。是他们利欲熏心，利令智昏，为自己的前途事业挖掘了陷阱，付出了沉重的代价。<BR>　　“君子爱财，取之有道。”谁不想手头宽绰一点儿？但必须是自食其力，用自己辛劳、汗水换来的应得之财，只有这样得到的酬劳之财，才是胡锦涛总书记倡导的“八荣八耻”中“以辛勤劳动为荣”所得到的光荣之财，才是真正的“取之有道”之财。“八荣八耻”集中体现的廉耻观、荣辱观，这是衡量为人处世是否有高风亮节的准则。<BR>　　钱是好东西，有了钱就有了一切，现在出现了金钱至上论调。毕竟人人都要生存，尤其是在人情日益冷漠的今天，所以有这些论调和思想也无可厚非。<BR>　　无论你是在单位或是经商，干什么工作都可以达到取财的目的，也不会遭到任何人的反对和干扰，可问题是在利益的驱动下，有些打着冠冕堂皇的下三流人物出现了，有好多是干部，国家公务员，毫不费吹灰之力就可以拿到10倍、百倍甚至更多的报酬。人都有个心理平衡，干活的拿不到多少钱，不干活的拿很多钱，如果整个社会长期都存在这种不均衡现象的话，恐怕天下就要大乱；更有甚者，背着良心拿黑钱，完全不顾别人的死活，也不管别人对自己的看法，这恐怕不得不引起国家发改委的重视。<BR>　　宋朝文学家欧阳修说：“廉耻，士君子之大节。”所谓“士君子”，现在就是包括国家公务员在内的广大知识分子阶层。而其中各级领导干部作为“士君子”的典型代表，更应具备高风亮节。事实上，绝大多数领导干部体现了我们党的优良传统作风：“节制私欲而守公德，坚持廉洁而知荣辱”。因为我们党是执政党，党的每一代领导人，总是告诫全党同志廉洁自律，特别是这次党的十七大代表提出的“务必继续保持谦虚、谨慎、不骄、不躁的作风，务必继续保持艰苦奋斗的作风”。各级领导干部只要牢记“两个务必”，真正将“两个务必”落实到行动中，才能克服可怕的贪婪之心，做到廉洁奉公，不辱使]]></description>

<link>http://tgzxs4.eduol.cn/archives/2008/701060.html</link>
<description><![CDATA[科学给人类突破自我提供了基础，凭借科学的翅膀，人类可以飞翔，那样的感觉有时候很冒险，很疯狂。科学以严谨著称，但科学飞跃的时代往往是充盈着狂想，狂想对于严谨，如同质变对于量变。对于具有狂想气质的科学家，无不具有艺术家的想象力。<BR>正如牛顿坐在苹果树下，看着苹果落地而发呆，然后疑问苹果为什么会落地。这一幕就像话剧里面的场景，也是童话书中可爱小卡通。那个小牛顿开始狂想！正如爱因斯坦，发现相对论的时候就像是一个自言自语的痴呆，有时那么着迷于自己的沉思，也会沉思和陶醉在自己的小提琴音乐里。不论是沉思里还是音乐的跳跃里，他的音乐里肯定有一曲是狂想曲。整个宇宙似乎都在他狂想着的脑海中。<BR>因此，科学需要狂想，需要一种热情，这种热情就像花儿开放一样地美好，也像孕妇生产一样苦痛和焦灼。而更多的时候，科学是枯燥的、烦琐的、甚至无趣的。尤其在你的想像受到局限，在科学中充满了很多夭折和破坏，充满太多狂想造成的疯狂，而且成为一种熟视无睹的欲求和潮流的时候。那么，科学就是危险的。<BR>因为，科学是阶梯，是武器。阶梯在送你去高处的时候，并没有为预见可能出现的倒塌做好保险准备。武器更是双刃剑。而这样的双刃剑还是很让人有后顾之忧的。<BR>如果狂想者能够像牛顿一样的谦虚平实，言称自己的终生之成就不过如同偶尔在海边荣幸的捡到的贝壳，浩淼海波，他以无比崇敬的心情感恩于造物主。爱因斯坦更是以人类之和平共处为自己终生之志愿，奔走于反法西斯的道路中，并其个性随和、天真、朴实、宽容大度。<BR>狂想者只有在闪烁着人性光辉的时候才能成为造福人类的大科学家，不然还是做个凡人的好。脚踏实地的做个科学工作者，希望如此，会少了浮躁、好胜、斗气，自然也会少了危险。<BR>即使没有狂想，也不要疯狂的沽名钓誉、唯利是图者。]]></description>

<title><![CDATA[如何提高青少年阅读品质]]></title>
<link>http://tgzxs4.eduol.cn/archives/2008/701058.html</link>
<description><![CDATA[阅读在青少年成长中的重要作用，已逐渐受到越来越多的人重视。阅读能启迪心灵，熏陶品格，提高素质，丰富精神。培养青少年的良好的阅读品质，目的就是引导青少年开阔视野，提高青少年的素养，促进青少年全面发展。如何培养青少年的阅读品质呢？<BR>培养阅读兴趣是关键。阅读品质都是阅读兴趣的拓展和延伸，一个不喜欢读书的人压根就谈不上阅读品质的问题。“强扭的瓜不甜”，因人制宜，制定确实可行的目标，充分激发调动起青少年阅读兴趣来，才能为提高阅读品质打下坚实的基础。要尊重青少年在教师和家长的引导下自由选择书籍的权利，尊重青少年的阅读兴趣和口味，然后加以因势利导才会取得成效。否则，依靠强制性举措是不会取得好效果的。<BR>为青少年营造一个良好的阅读社会文化氛围。这需要社会、学校和家庭的共同努力。青少年的阅读现状不容乐观，农村孩子的阅读范围局限在几本教科书，城里孩子的阅读范围被“太多太杂”的书籍所占领。青少年阅读的小环境离不开国民阅读的大环境，要认真实施“文化环境保护工程”，营造良好的全社会读书氛围，让青少年耳濡目染。学校要设立“读书日”，让所有的青少年都能享受阅读的乐趣。<BR>让青少年有好书可读，并在好书的圈子里博览群书。“以优秀的作品鼓舞人”，要鼓励青少年阅读名著，要看高品位的书，抵制格调低下的书。在好书中，还要引导青少年博览群书，读文学，也要读人物传记、思想理论、科普书、数理化、文史哲。正如蜜蜂，只叮在一处便枯燥了。要注意及时订阅好的期刊和报纸，以便跟上时代的阅读潮流。如《中学生阅读》、《语文报》等报刊。要引导青少年多到书店去走走看看，选购一些感兴趣的好书。教会学生辨别能力，自觉抵制品位不高的书，逐渐把兴趣转移到中外经典名著等好书上来。<BR>教师和家长要给青少年提供良好的阅读指导。学校是青少年读书的主场所，教师的阅读态度，直接影响青少年学生的阅读行为。教师要巩固青少年已有的阅读兴趣，激发和促进学生阅读品质的全面发展。家庭是青少年读书的又一个重要阵地。家长同样扮演着非常重要的角色，父母爱读书，家中拥有一定的藏书，这是对子女最好的阅读引领。家长要对孩子的自主阅读行为及时进行鼓励和赞赏，激发他们的阅读兴趣，提升他们的阅读品质。教师和家长要在阅读引领中，还要及时感知青少年阅读情感的变化，青少年的阅读情感的变化可以直接激发青少年的阅读兴趣，要帮助青少年树立阅读自信，加强阅读意志的锻炼。<BR><CLK>开展丰富多彩的读书<NOBR oncontextmenu="return false" onmousemove=kwM(0) id=clickeyekey0 onmouseover="kwE(event,0, this)" style="COLOR: #6600ff; BORDER-BOTTOM: #6600ff 1px dotted; BACKGROUND-COLOR: transparent; TEXT-DECORATION: underline" onclick='kwC(event,0,"")' onmouseout=kwL(event,this)>活动</NOBR>，在活动中提高青少年的阅读品质。只凭教师和家长的空洞说教，容易触发青少年的逆反心理。青少年处在心智成长期，自制力相对较差，自觉性相对不高，缺乏恒心和毅力，往往是对读书的意义心知肚明，但缺少深入读书的实际行动。为了让青少年更好地体会阅读之乐，就要通过开展丰富多彩的活动来激发调动。可以通过举办阅读沙龙、座谈交流、书评竞赛、读书笔记展评等形式，为青少年搭建多彩的阅读舞台，然青少年在舞台上精彩展现。</CLK><BR>“腹有诗书气自华”，读书贵在有恒，要引导青少年把读书看作“日课”，形成每天读书看报的好习惯，循序渐进，日积月累，逐渐在读书中培养了语感，积累了知识，提升了品位，增强了情趣，最终提高了阅读品质。]]></description>

<description><![CDATA[在上世纪九十年代有了它的影子后，人们就觉得它是多么神秘而又高档的东西呀。随着人们对它的进一步的了解，得知它是一种非常神奇的一种高科技产品。是它的诞生，让国防、科技、政治、军事等现代化得以迅猛的发展。也是科学的发展，让它的版本一次一次的提升。</CLK><BR>进入21世纪后，宽带一步步地通向全国各个角落，电脑也就相应地进入了寻常百姓的家中。人们可以通过网络学到许多知识，增长见识，可以在网络上畅游世界，通过网络连接的电脑，如同一个庞大的图书馆，又如同一个游乐场，在汲取知识的同时，又可以娱乐，开发大脑，调理情序。然而有的人却歪曲了它的用途，扭曲了它的真正价值。<BR>我们经常听说许多学生因沉迷网络面耽误学业，许多青年而堕落法网的事。我觉得那些事都离我们太遥远了。然而，随着电脑的普及，在给人们带来快捷、方便的同时，也真的带来许多不利因素，终究是谁的原因呢？<BR>迷恋网络游戏，顾不上吃饭、干活的有之，夫妻为此吵架，摔砸电脑。迷恋网络聊天，寄情感于网络，在网络中寻找浪漫，不能自拔者有之。尤其是女姓，平淡的婚姻让她们再也找不到激情，而网络那端一句火辣辣地问候，就点燃了那颗已经濒临熄灭的火种。而网那头的他却在偷着笑。当她思念的短信一条条发去时，却是别人的手机。当她被邀出现在视频上时，却有好几个人在一旁笑看。面对他灸烈的爱意，她时刻准备着破网相见，而那头的他却还在撩拨她真挚的情感。直到有一天，她发现被骗了，才觉得累了。更有甚者，抛弃家庭，抛弃孩子，当发现自己舍之一切追求而来的幸福却是一颗婴粟时，再回首，满脸的沧桑再也找不到原来平淡中的温暖。<BR>还有陷的更深的，就是在网络上寻找刺激。丈夫上夜班，女人在家上网等候。慢慢地她寻找到了一种颇俱情调的玩法，淫笑荡语充沛了整个夜晚，扰乱了邻居。当恩爱的丈夫气急败坏地摔了给它工作带来方便的电脑时，她也消失了。街头巷语让这位有头有脸的男人发出了歇斯底里的吼叫：“就是离婚，也要砸折她的腿。”<BR>难道这就是高科技的产物——电脑带给我们的吗？听到这些真实的故事，我真的很惊讶，也很痛心。电脑离我们越来越近了，在拥有它的同时，谁都不想它成为家庭吵架的气包子，也不想成为造成家庭战争的爆炸器，更不想成为引爆家庭破裂的导火线。<BR>说到这，我觉得太沉重了，电脑、网络，在科技发达今天，在充满诱惑的虚幻世界里，我希望接触电脑的朋友们好好地利用它的价值，把握前进的方向，让它成为我们生活中不可缺少的伙伴。<BR>]]></description>
