【天下没有免费的午餐】青年苦读练就纯正美式英语,冒充大学老师骗财色
青年苦读练就纯正美式英语，冒充大学老师骗财色一名80后农村青年，靠着自己在大学期间的勤学苦读，练就了一口令人艳羡的纯正美式英语。
然而，他没有用其技能为自己谋取一份好工作，多年来竟一直冒充大学老师以骗财、骗色为生。
今年3月1日，本报的一篇报道促使此人落网。
昨日（19日），从（武汉）江汉区人民法院传来消息，“此人因盗窃、诈骗二罪并罚，被判入狱11年。
据了解，这名冒充高校老师行骗的男子，名叫樊志敏(曾用名凡志敏、王杰、绰号“阿奔”)，生于1982年6月，毕业于武汉某大学国贸专业，是本省天门市小板镇张岭村六组人，大学毕业后一直处于无业状态，但却能屡次骗财、骗色得手。
早在2009年就被樊某骗去3万元的左先生告诉记者，樊某的行骗对象多为涉世未深的年轻人或女性，行骗时间大约有七八年，行骗地涉及广东、上海等地。
因曾屡次使用真名或“凡志敏”行骗，网上有大量的受害者声讨他的网帖。
其关键的行骗技能就是一口流利的英语。
据多名受害者介绍，用英语跟不认识的女性搭讪是樊某行骗的第一步。
樊某通常会穿着一身名牌，在时尚商场或品牌电器店游荡，在看准目标后先与对方搭讪，并伺机让自己的手机响起，随后就用英语“接”电话，当发觉对方向其投来钦羡的眼光并询问其英语为何如此流利时，樊某再自然道出自己是“高校老师”。
如果对方对其说英语并不感冒，他便会重新选择下手对象。
第二步，与成功搭讪的女性建立恋爱关系。
在显露了自己的英语技能后，大多数被搭讪的年轻女子都会对其产生好感。
加之樊某英语流利，结识了不少高校的留学生朋友，他便经常将初识的女子带到留学生宿舍游玩，不少初识女子就更加信任樊某的“老师”身份。
此时，樊某就会伺机与对方建立恋爱关系。
第三步，以升职、买房急需钱向“女友”及其朋友借钱。
为了给自己的“高校老师”身份圆谎，平时没有收入的樊某经常会重复使用第一步搞些“短打”，在初识女子掉以轻心时偷盗对方的贵重物品，然后再用这些贵重物品“武装”自己，博取“女友”家人和朋友的好感。
表达天下没有白吃的午餐的句子
表达天下没有⽩吃的午餐的句⼦1. 请问"天下没有⽩吃的午餐"这⼀句话是从哪⾥来的智慧之书的第⼀章，也是最后⼀章，就是天下没有⽩吃的午餐。
天下所有的智慧是要通过努⼒来取得的，如果不通过⾃⾝的努⼒，你永远得不到属于⾃⼰的智慧，简⽽⾔之，天下的智慧其实就是努⼒，想要不通过努⼒（吃⽩饭），你是永远⽆法得到你想要的东西.所以做事要努⼒.天下有⽩吃的午餐是从经济学的⾓度来说的，它与我们息息相关。
经济学来源于⽣活，他的最终⽬的也是为⽣活服务的。
谈到经济学在⽇常⽣活的运⽤，这个运⽤可谓⽆处不在。
这句话的潜台词其实就是“没有不劳⽽获”的事，它的意思告诉我们，什么事情都要有所付出，不付出就想得受益，不付出就想捡到便宜，那是不可能的。
2. 表达午餐的句⼦有哪些1、营养午餐对⾝体有好处，我们应该要多吃，这样才会有健康的⾝体。
2、这次的午餐营养很丰富。
3、你有明天午餐的⾷谱吗？4、这顿午饭我吃得好饱。
5、今天胃⼝不太好，午饭煮⼆汤三菜四⾁就好了。
6、这顿午餐⼗分丰盛，飞禽⾛兽全在盘⼦上了。
7、中午在学校⾷堂吃的午饭。
8、今天中午⼜吃剩菜。
9、天下没有⽩吃的午餐。
10、单位炒的辣椒炒⾁很特别，我们每天中午最喜欢玩的游戏就是找到底有⼏⽚⾁，我们的最⾼纪录是3⽚。
11、中午还是回家吃饭吧，外⾯的菜不⼲净。
12、那家餐厅味道很好，我们下次约会可以去那吃午饭。
13、今天中午的⼯作餐味道还不错。
14、午饭吃的太饱，下午会⾮常困。
15、午饭吃完了我们出去⾛⾛，散散步。
3. 以论点为‘’天下没有⽩吃的午餐”写⼀篇议论⽂优质解答不知道你是初中的还是⼩学的，但我直说的话请别⽣⽓，在我看来这篇作⽂有以下⼏点问题：1、举的例⼦有误，所谓“免费”的午餐指的是不需要通过任何劳动或者付出任何代价就可以⾏到的，⽽你举的宠物狗和乞丐是分别是付出了⾃由与尊严才换取到⾷物的，所以并不能说是免费的.2、中间的例⼦占⽤篇幅太过，开头和结尾都⽐较敷衍，并不能很好的表达出你想传达的意思，3、部分语句不通顺，如“我还在苦苦的……⼀份免费午餐”这句语⽓不连贯，再有“⼀看就是它的主⼈对它百般呵护”我认为应该可以改为“显⽰出它平时受到了主⼈百般的呵护以及享受的可⼝的⾷物‘，这有⼏处请仔细查看；4、整篇⽂章结构不够严谨，思路不够明确，语句不够通顺，⽴意不够明确，虽然能看出作者想表达什么的意思，但整篇⽂章却没有很清晰的表达出中⼼思想，虽说写作不要求有华丽的词藻，但字词应使⽤恰当，才能组成⼀句能表达⽴意的语句不过，作者能⽤例⼦来表达出⽂章的中⼼思想也是⼀个不错的想法请别⽣⽓。
浅析“天下没有免费的午餐”
浅析“天下没有免费的午餐”一、“天下没有免费的午餐”由来《贝尔格莱夫经济词典》中“免费午餐”词条：免费午餐”一词始见于19世纪，当时的酒吧和客栈，为了吸引客商光顾，纷纷在门外张贴广告，以“提供免费三文治和零食”为招徕；但顾客若只吃三文治而不“买醉”，很快就发现不能照字面解释来理解这句广告。
不买饮料只索取三文治的人，毫无例外被“抛出门外”。
显而易见，“没有免费三文治”，是“没有免费午餐”的“前身”。
货币学派大师佛利民，于1997年6月中旬，前往以色列接受希伯莱大学名誉博士学位时，与以色列国会财经委员会主席路年思言谈甚欢。
路年思说，犹太教教义可用“已不欲，勿施于人”八个字概括之，其余都是次要；他请佛利民用一句简单的话来概括其经济学精义，佛利民脱口而出：“世上没有免费午餐是我的经济理论的全部，其余只是枝节!”政治学家杜兰曾提出两大原理，其一是“世上没有免费午餐原理”，其二是“世上没有无懈可击的影响力原理”。
二、天下没有免费的午餐“免费午餐”通常是骗局，尤其是出现在大众媒体上的时候。
通常来说接受过一些投资教育，或者是有实际投资经验的人会知道收益和风险是对等，天下没有免费的午餐。
那么“免费午餐”是否真的不存在呢？存在的。
但是普通人要吃到免费午餐条件极为苛刻。
（1）免费午餐的存在时间极为短暂，可能会出现走路捡到钱的情况，但是如果不去理睬它，很快会被其他人捡走。
（2）免费午餐发生的概率很低，可能四五年会捡到一张10元，但是如果不是专业捡破烂，不会天天捡到钱。
（3）免费午餐存在的信息只被很少人知道，假设某个自动售货机经常会有1元硬币掉出来，而这件事情又被众而周知的时候，蜂拥而来的捡钱大军会让再次捡到钱的概率大大降低。
（4）免费午餐不需要大量的精力和金钱投入，也就是不能有很高的门槛，通俗地说，就是普通人也能吃到的免费午餐。
比如有些人会在外国运入的废旧汽车里面找硬币赚钱，这是他们的主要工作之一，要付出不少的精力成本。

高三精选作文：天下没有免费的午餐
高三精选作文：天下没有免费的午餐
我不知道现在的人们为什么那么的热衷于免费，并且对免费的东西，有种近乎于狂热的执着。
看看朋友圈，如果哪个人说，免费送什么东西？看看下面一定是长长的评论，怎么送？送什么？真的吗？
大概，以前的自己也是这样的吧。
可是，现在看到这些消息，都移动到忽略。
有的时候，我宁愿去掏钱买，而这些所谓的免费送，你问问，大都是买一个别的东西，才会免费送一个小东西。
所以，时间长了，我还是坚信，天下没有免费的午餐。
而且，的时候，我们应该注意的是，这些免费送的东西，会不会有骗人的陷阱。
每次看到那些谁谁谁被骗多少钱的新闻，都会感到很心疼。
挣钱，谁都不容易。
就这么轻易被骗，也真是可怜。
可是，仔细一想，这又能怨得了谁。
真希望每个人都可以睁大眼睛，看清楚身边的这些免费东西是不是安全。
因为，真的是，天下没有免费的午餐。

10个英文成语详解
10个英文成语详解10个英文成语详解所谓的精选就是字字珠玑, 没有烂竽充数的意思. 虽然英语的成语何其多, 没有几万也有几千, 小笨霖不求一网打尽, 但求每个列举出来的成语都是真正有用而且非常好用的成语.例如像是, "说曹操曹操就到"这句中文里耳能详的成语, 你知道英文版要怎么说吗? 答案就在下面喔!1. Speak of the devil.说曹操曹操就到.有些中文的成语用直接用英文翻出来老美还可以接受, 但是"说曹操, 曹操就到" 这句话要翻可就没有那么容易了.而何况你还要先解释曹操是谁, 那难度又更高了.以前我不会 Speak of the devil 时, 我都是说, That's a coincidence. (那真是一个巧合.) 但是大家现在学会了这句之后, 又更加好用了.下次当你们谈到某人, 某人就正好出现时, 你就可以说Speak of the devil. 或是 Talk of the devil.2. That's the best thing since sliced bread.那是有史以来最好的事情.像这句话要避免说成, the best thing in the history, 听来就不那么道地.老美他们都是用 the best thing since sliced bread 来表示有史以来最好的事情. 这句话的典故是这样的, 在 1928 年以前, 在美国所贩卖的面包都是整条没有切过的.所以面包买回家后还要自己切. 后来有一个密西根人Otto Rohwedder 发明了切面包的机器, 美国人一时之间觉得这种机器实在是太神奇了, 所以往后要是有什么很棒的事情发生, 他们就会说那是自从切面包的机器发明以来最好的事情. That's the best thing since slice bread. 这句话我常听到, 例如有一次网路银行Net Bank 的广告就说, Net Bank is the best thing since sliced bread.或许你会跟我一样觉得实在很可笑, 因为美国历史上重要的发明何其多. 这个切面包机可能连前一百名都排不进去, 为何把它的发明说成是最棒的事呢? 这个问题也许就要留给老美了. 不过如果你要展现一下自己的创意和幽默感, 建议你可以'故意'把这句话说成, That's the bestthing since the invention of space shuttle. (自从太空梭发明以来最棒的事.)3. When in Rome, do as the Romans do.When you are at Rome, do as they do at Rome.入境随俗.在美国有一群特殊的美国人, 他们坚持用传统的方式生活, 自己耕种, 驾马车, 不用电, 不能拍照. 这群人就是 Amish. 也因为这样, 很多他们居住的地方现在却成了观光胜地.听来很讽刺, 不是吗? 话说上次我去某个个 Amish 的市集买东西时, 看到很多的 Amish. 我好奇之下就问其中一个作 Amish 打扮的人说, Are you Amish? 结果你猜他怎么说? 他说, When in Rome, do as the Romans do. 天啊! 原来是个冒牌货! 所以大家下次不要再被骗了.从字面上的意思来看, When in Rome, do as the Romans do. 就是说当你在罗马的时候, 要表现的跟罗马人一样, 所以就有入境随俗的意思在内.另外关于罗马还有一些很常听到的成语可以顺便记一下, Rome was not built in a day. (罗马不是一天造成的.) All roads lead to Rome. (条条大路通罗马.)4. The lesser of the two evils.二颗烂苹果中比较不烂的.记得我刚来美国时我都会把这句话照中文的字面意义下去直接翻译, 说成, The better one of two rotten apples. 当然老美也是听得懂.直到有一次我班上的同学纠正我说, 这句话应该是The lesser of the two evils. 意谓著二恶相权取其轻. 说得再口语一点, 就是二颗烂苹果中比较不烂的意思吧!5. This is like chickens and eggs.这就像是倒底是先有鸡还是先有蛋的的道理.记得我在小学的时候我就会问, 鸡生蛋, 蛋生鸡, 那到底是先有鸡还是先有蛋.这个问题到我现在念到博士班了还是不会.所以看来这二十年是不是有点浪费了? 回到主题, 任何不知道时间先后的事情我们都可以用 chicken and eggs 来形容. 例如, 到底是有钱才去从政还是从政之后才有钱? This is like chickens and eggs.6. Beauty is in the eyes of the beholder.情人眼里出西施.这句话大家都不陌生吧! 要是看到某个美男和某个丑女走在一起, 你就可以深表婉惜地说, "Beauty is in the eyes of the beholder." 总之这是各人喜好, 我们也不便多说什么. 另外有一句成语, 一朵鲜花插在牛粪上, 我曾试著用 A flower in the bullshit 来诠释, 可惜似乎老美不太懂我在说些什么. 各位有什么更好的建议吗? 至于速配的'话, 可以试试, Every Jack has its Jill. (破锅自有烂盖配.) 或是 Let beggars match with beggars. (乞丐配乞丐)7. Practice makes perfect.熟能生巧.不但是音乐家也好, 运动员也好, 在他们的成长过程中, 总是需要不断的练习才能有完美的演出. 这就造就了一句成语, Practice makes perfect. 鼓励别人要不断地去尝试错误.类似的成语例如 When at first you don't succeed, try try again. (如果一开始不成功的话, 要不断地尝试下次, 注意这里的 try try again 不是我多打了一个 try 而是老美真的是这样说的.),8. There is no such a thing as free lunch.天下没有白吃的午餐.这句成语太出名了, 似乎没有人不知道.这也是经济学的理论基础吧! 天底下没有那么好的事情可以不劳而获. 总之, 当我们听到一件事情好到不可思议时, 例如一元手机, 免费上网, 我们就可以对别人说, There is no such a thing as free lunch.但是有规则就有例外, 个人觉得美国的教会或是救世军(Salvation Army) 之类的慈善组织就蛮喜欢请大家吃免费的午餐.例如他们有时会办一些免费的 BBQ, 随到随吃, 吃到饱为止, 完全打破了天下没有白吃的午餐这个规则.9. If you can't dazzle them with your brilliance, baffle them with your bullshit.如果你无法用你的才能无法说服别人, 就用你的废话迷惑别人吧!这也许是个不争的事实, 老美在数理的基础上也许不如我们东方人, 但他们在数据收集, 上台报告方面却硬是比我们强上一大截, 这或许也是外国人无法在美国站上主流社会的原因之一吧! 所以各位要记得, baffle others with your bullshit. 把三分的结果加上七分的 bullshit. 就能拿到一个十分的成绩. 或许很讽刺, 但现实生活不也是如此吗?还有一些类似摆烂的成语, 蛮有趣的, 例如, If everything else fails, manipulate the data. (如果所有的方法都失败了, 就试著去改变量据吧!) 或是 If at first you don't succeed, destroy all evidence that suggests you tried. (如果你不成功, 就把建议你这么作的所有证据都给毁了.)10. God is shining on you.你真是幸运.God is shining on you 就是指一个人非常幸运, 也就等于 You are very lucky 的意思. 例如大家修理一台机器都修不好, 结果你一来一下子就把问题给找出来, 别人就会对你说 God is shining on you.。
英语文化小常识
英语文化小常识There's no such thing as a free lunch我们常常听说这样一句话：There's no such thing as a free lunch.（没有免费的午餐），你知道这句话是怎么来的吗？十九世纪的时候，美国有些酒吧给顾客提供“免费的午餐”。
所谓午餐，其实不过是些用来和啤酒一起送出的脆饼；而所谓免费，当然不是真的，不买酒喝就没有饼吃。
所以，当时有人说：There's no such thing as a free lunch.到了二十世纪七十年代，经济学家弗里德曼 (Milton Friedman)写的一本书用了这句话做书名。
他在别的著作、演讲里也多次引用这句话。
于是，这句话就又流行了起来。
有时，我们不相信会得到一些优惠，就可以用这句“弗里德曼名言”。
例如： I don't believe he's giving us the money without any ulterior motive. There's no such thing as a free lunch. 我不相信他送钱给我们不是别有用心，世上没有免费的午餐Honeymoon大家一定都知道honeymoon吧，honey（蜂蜜）和 moon（月）结合在一起的意思就是“蜜月”。
honeymoon指的是新婚夫妇结为伉俪的最初一段时光（并非一定是结婚后的第一个月，虽然很多人都有这样的错觉）。
爱情经过长久的期盼和耕耘，相爱的情侣终于手拉手走到了一起，双方的感觉能不像蜜一样甘甜醇美吗？有一种说法认为honeymoon这个词来源于巴比伦的民俗传统。
这个古老的国家一直保留着这样一个传统，在女儿出嫁的第一个月，女孩的父亲每天都会让女婿喝mead（蜂蜜酒），以希望后辈们的婚姻永远幸福甜蜜。
然而，从词源学的观点来看，这种说法是错误的。
honeymoon 最早出现于16 世纪，honey 用以喻指新婚的甜蜜，但moon并不是指很多人认为的阴历月份(lunar-based month)，它是一种苦涩的暗示，旨在告诫人们婚姻固然是幸福甜美的，但这种甜蜜就像月亮的盈亏，只是暂时的（因此要十分珍惜才对喔！），婚姻更多的意味着双方要一起肩负生活的重担，一起承受人生的酸甜苦辣，一起经受生活的风风雨雨Darlingdarling可能是英语中最流行的昵称了，也是最古老的词语之一。

英语阅读带翻译校园小故事mp3在线听天下没有免费的午餐No Such Thing as Free Lunch天下没有免费的午餐Ever since Mary moved to the United States one year ago, she often heard the phrase "no such thing as free lunch". While she understood this to mean that you can't get something for nothing, she heard other mothers at her child's school talking about the free lunch program.自从玛丽一年前搬到美国，她经常听到“天下没有免费的午餐”。
她明白这意思是你没有付出就不会有收获，她听到其他母亲在她孩子的学校谈论免学费的事情。
"How much does it cost to enroll?" Mary asked the secretary at her child's school. The secretary smiled and told Mary that it didn't cost anything except a little bit of time. In order to find out if Mary's child was qualified to get free lunch at school, she had to fill out a form. The form was available in many languages besides English. It asked Mary basic questions like where she lived, how many children she had, and what her annual income was.“要参加这个需要多钱？”玛丽问她孩子的学校秘书。

天下没有免费的午餐？
天下没有免费的午餐？作者：俞可杨薇来源：《世界教育信息》2013年第17期摘要：全球学校供餐计划保证了儿童的健康与营养，有效提高了学龄儿童的入学率和出勤率，但在实施过程中困难重重，印度学生午餐中毒事件凸显了全球供餐计划在食品安全等方面存在的诸多问题。
世界粮食计划署发布的《全球学校供餐现状调查报告2013》阐述全球学校供餐计划存在的问题，并提出解决方案。
各国政府应承担起责任，将学校供餐计划与国家的长期发展联系起来。
关键词：全球学校供餐报告；世界粮食计划署；印度比哈尔事件；政府责任“天下没有免费的午餐”，这条广为流传的定律已被破除，遍及全球的学校供餐计划使亿万莘莘学子受益。
该计划发端于20世纪中叶的富裕国家，实施手段大致可分为两大类，分别为学生接受在校供餐模式和将配给的口粮让学生带回家模式。
学校供餐计划既是一项社会福利，也是一种教育普及。
然而，7月中旬在印度突发的小学生集体中毒事件为该计划蒙上了阴影，进而鞭策各国理性审视并合力推进这项功在千秋的事业。
一、印度事件责问功过是非今年7月12日，印度比哈尔邦瑟伦区甘达曼村一所名为达拉姆萨蒂的公立小学，27名4～12岁小学生食用学校提供的免费午餐后因食物中毒死亡（以下简称比哈尔事件），全球震惊。
印度是学校供餐计划（在印度被命名为“午餐计划”）实施规模最大的国家，至2011年已覆盖全国约120万所学校，惠及1.136亿多名中小学生。
2010-2011年度，中央政府和各邦政府对学校供餐计划的耗资总额高达38.5亿美元。
对于这个高举脱贫大旗的发展中国家，该计划无疑是一项史无前例的善举，绝不会因某一个突发事件而因噎废食。
正如媒体所言，午餐计划是印度穷人唯一真正广为受益的项目，用比哈尔事件抨击甚或否定午餐计划，将会在印度造成更大悲剧。
该计划可追溯到上世纪60年代在泰米尔纳德邦展开的试点。
1995年，中央政府启动旨在确保小学生就学与营养的“小学教育营养支持全国项目”，每天为每位小学生提供100克大米或小麦，并为粮食的运输与管理发放补贴，邦政府则负责提供配套的原料、劳力、场地及设备。

天下没有免费的午餐励志文章
天下没有免费的午餐励志文章天下没有免费的午餐励志文章俗话说，天下没有免费的午餐。
虽然这是天下人人尽皆知的道理，人，作为理性和感性相结合的动物，难免被外界的喧嚣蒙蔽双眼而冲动地参加免费的盛宴。
又是一年双十一，这个特定的日子，阿里用短短10年时间，把它从单身男人哭的日子变成了已婚男人哭的日子。
作为全国乃至全世界规模最大的全民网络购物狂欢节，成交量之大，速度之快，让任何一个商家都不敢轻视，当然商品折扣力度也是很大的。
买卖之间，信息不对称永远是一个存在的问题，尽管因为互联网的出现，信息不对称的情况在降低但却一直存在。
因为买卖双方信息完全对称，那么商家就不可能获得利润，无法推动商业的发展。
记得以前的一段网购经历，在购买了一批商品后，电商平台送了100元、50元不等的购物券购买达到一定金额的指定商品后可以抵扣相应的金额。
虽然，我们都自称是理性消费人，但看到相应的购物券后，贪便宜的`心理油然而生，对指定商品里自己心仪的商品。
作为所谓的理性，既要对商品进行组合，又要计算使用购物券达到最大化。
不知不觉中，1小时过去了，在最终确定购买的商品后，一阵好奇心驱使，想看看其它电商平台的价格，却发现另一家电商平台的报价是抵扣购物券之后的价格，我果断地放弃购物。
虽然没有购物，平台没有成功交易商品，自己也没有损失，仿佛是自己的计谋更胜一筹，没有落入陷阱。
但我却在对比、查找商品中丢失了1小时的时间。
也许，有人会说1小时也没什么了不起的，起码你也浏览了很多的商品呀。
但这1小时本来我可以做其它的事情却浪费在对比、查找当中。
当问到世界上什么东西最贵的问题时，答案可能是仁者见仁，智者见智。
我很想借用以前音频里听到的一段答案：免费的东西最贵。
当然，人性的弱点又决定了我们会在某些情况下追求免费。
在停车场或者路边收费停车的地段，开车一族大多会逃费的经历，或者总想把车停在不收费的公路一侧，虽然小城市的停车收费费用并不算高，但我们停车首选当然是不收费的地方，而不论我们的座驾到底是豪车还是代步车，人性使然而已。

The cafeteria ladies give us a tray with food like chicken nuggets, pizza, or a peanut butter and jelly sandwich. We don't have to pay any money for it. So how can there be no such thing as a free lunch when I get one every day?My dad tried to explain it to me. He said the lunch isn't really free because my parents and other people in our town pay taxes. Part of that tax money goes to the school to pay for the free lunches. So while I don't pay for my own lunch, someone else has to pay for it with their taxes.I still don't really get it. If I don't have to hand over any money for my food, isn't that a free lunch for me? I mean, I know my parents pay taxes, but they would have to pay those anyway whether I got a free lunch or not. It seems like a free lunch to me!Dad says it's just a saying that means you can't get something for nothing. Everything has a cost, even if you don'tsee it right away. He told me to imagine I did some work around the house like cleaning my room. If my parents then gave me 5, it wouldn't really be free money. I had to work for it by doing my chores first.The Same Goes for School LunchesThe lunch ladies at school didn't just wake up one morning and decide to make free food for everyone. The lunches get paid for somehow - through taxes, fees from the government, or fundraisers. Someone has to pay for the food, the cooking equipment, the workers' salaries, and all the other costs. Even though I don't personally pay anything for my school lunch, there's no such thing as a totally free meal. Somebody always has to cover the cost.I think I kind of understand the idea now, but it's still confusing. Like when I go to my friend Danny's house, his mom always gives me a snack like chips or cookies for free. She doesn't make me do any chores or pay any money. Isn't that a real free treat then? My dad disagrees.He says Danny's mom didn't really get those snacks for free either. She had to pay for them at the grocery store using the money she earned from her job. Or maybe Danny's dad got paid, which gave them money to buy the snacks. Somebodysomewhere had to put in work or spend money to get those free chips and cookies. There's always a cost to getting things, even if we don't see it.The Same Applies to Other Free StuffDad gave me another example: Let's say you go to a baseball game, and they're doing a giveaway, tossing free t-shirts to people in the crowd. You catch one, so you got a free shirt, right? Wrong!The baseball team had to pay to make those shirts. The cost gets built into things like higher ticket prices so they can afford the giveaway items. Or maybe they have businesses sponsor the shirts by putting logos on them. Either way, somebody spent money on those "free" shirts.This whole "no free lunch" thing seems to apply to all sorts of situations:• Free software usually has ads to make money• Free apps might share your personal data to make money• Free to play games push you to buy upgrades• Free samples are used to get you interested in buying the full productBehind anything labeled "free," there's usually some way the company is still making money or getting something in return. Otherwise, they'd just go out of business from giving stuff away without making any profit!It Makes Me Appreciate Things MoreLearning about this "no free lunch" concept has made me think more about howmany people's effort and money goes into making the things we use and consume every day - even stuff that seems totally free to us. Now when I get my free school lunch, I make sure to at least say "please" and "thank you" to the lunch ladies. They work hard to provide those meals, and I'm grateful my parents' taxes help pay them.I also don't take "free" things for granted as much. Like when we got those free t-shirts at the baseball game last summer, I made sure to wear and enjoy it instead of just throwing it aside. Somebody put in effort and resources to create that "free" shirt, so I should appreciate it.The idea of "no free lunch" has also encouraged me to start working harder myself. I help out more with chores at home, because I realize when my parents pay me an allowance, that money isn't totally free - I'm earning it a bit through my work. I've started a lemonade stand too, so I can make my own moneyto buy video games instead of just asking my parents for free games. It feels better to pay for stuff through my own efforts.In the end, I guess this whole "no free lunch" thing means we should appreciate the time, labor, and money that went into creating every product we use - even stuff that seems free to us at first. We shouldn't take those "free" things for granted, since they're not really free. The phrase reminds us that everything has a cost, even if we can't directly see it. Now when I get my next free lunch at school, I'll be sure to say an extra "thank you"!篇2No Free Lunches? I Beg to Differ!When my parents or teachers use the expression "there's no such thing as a free lunch", I can't help but feel a bit skeptical. After all, I've gotten plenty of free lunches in my life! Just last week, my friend Johnny shared his sandwich with me because I had forgotten my lunch at home. And at my birthday party, I got a free slice of cake from the pile my mom had made. So clearly, there are free lunches out there if you look hard enough!But I know the grown-ups don't actually mean it literally when they say that phrase. They're using it to teach an important lesson about economics and life. From what I can gather, itmeans that you can't get something for nothing. Everything has a cost, even if that cost isn't money.For example, when Johnny gave me half his sandwich, it didn't cost me any money. But it did "cost" Johnny half his lunch that day. So while the sandwich was free for me, it came at the Price of Johnny going a bit hungrier until dinnertime. There was a trade-off involved.Or take the free slice of birthday cake. Sure, it was free for me to eat it. But someone had to pay for the ingredients to make the cake. Not to mention all the work and time my mom spent baking it! Just because I didn't have to pull out any cash, doesn't mean the cake was truly free of all costs.The more I think about it, the more this idea of "no free lunches" makes sense. Every single thing in life has some kind of cost or trade-off. Even doing things that are free of money costs you something else, like time or effort. To earn good grades, I have to pay the cost of studying hard instead of playing video games. Getting to run around at recess takes the cost of sitting still during class first.In fact, I'd say there are very few things in life that are completely free of any costs at all. The only example I can really think of is just breathing the air around us. But even that's nottotally free, since trees and plants have to do tons of work making our air breathable! We just don't directly pay them anything for doing that hard work.This whole idea helps explain something I never understood before - why my parents are so careful about how they spend money. For a long time I thought they were just being mean or stingy when they would say no to buying me a new toy or taking me out for ice cream every night. But now I realize that money doesn't come out of nowhere for them. Every dollar they spend on something is a dollar they can't spend on other important things we need, like food, clothing, or paying the bills. There's always a trade-off when using limited resources like money.So while free lunches may exist in the most literal sense, the saying is really teaching that nothing is truly free from all costs when you look at the bigger picture. Every choice has an opportunity cost - meaning what you give up to get that choice. When I choose to spend all my weekly allowance at the arcade, the cost is not having that money to buy a new book I wanted. Getting good grades costs time I could have spent playing instead. Nothing is free!I think the "no free lunch" rule applies to big things in life too, not just little choices. For example, I want to play professionalsoccer when I grow up. That's not going to be free. I'll have to pay the cost of exercising and training really hard for years and years. Or say I want to be an astronaut - that means I'll have to pay the cost of studying sciences like crazy so I can get into a great college. Every dream job or amazing opportunity will require paying some sort of costs to get there.Now that I'm wrapping up this essay, I realize just how smart and true that little phrase really is. You really can't get something for nothing in this world. Every single thing we enjoy has involved someone, somewhere paying a cost to make it happen - even if we don't directly pay for it ourselves. There's no such thing as a free lunch. But as long as we're willing to pay the necessary costs and make the required trade-offs, we can work toward getting those things we want most in life. No dream is free, but all dreams are possible if you're willing to pay the price!篇3There's No Free LunchHave you ever heard the saying "There's no such thing as a free lunch"? It's a weird phrase, isn't it? I mean, of course there are free lunches - my school has a free lunch program where kids can get a sandwich, a piece of fruit, and milk for no money at all!And sometimes when I'm out with my parents, the restaurant will give free bread or tortilla chips before the meal. So what does that strange saying really mean?Well, after thinking about it for a while, I think I understand. You see, even though those lunches are free for me, someone still has to pay for the food somehow. The school lunch isn't really free - it's paid for by taxes that everyone chips in. And those free appetizers at restaurants? The cost is just built into the prices for other menu items. Nothing is truly free - there's always a cost that someone has to cover.That's the basic idea behind "there's no free lunch." It means that you can't get something for absolutely nothing. Everything has a price or a trade-off of some kind. Let me give you a few more examples to explain what I mean:Last summer, my parents and I went to a waterpark. The tickets were pretty expensive, but they let kids under 10 get in free with a paying adult. So I got in free, right? Not really. My parents had to pay a lot for their tickets to cover the cost of me getting in "free." If they hadn't brought me along, their tickets would have been cheaper.Another example is with video games. Sometimes you can download a game for free, but then you'll get bombarded withads or they'll try to get you to pay for extra features once you're hooked. The game itself isn't really free - you're either dealing with annoying ads or feeling pressured to spend money once you're playing.Or what about "free" samples at the grocery store? You get a little bite or drink for free to try a new product. But of course, the company is just hoping you'll like it enough to buy the full-priced item. They're not giving it away out of the goodness of their hearts - it's a sales tactic! The "free" sample has the hidden cost of trying to make you a paying customer.I see this principle at work with my own allowance too. My parents don't just hand me money for free - I have to do chores and behave well to earn it. The money itself isn't free; I have to "pay" by working for it. If I slack off on my responsibilities, my allowance gets taken away.In fact, pretty much everything in life works this way when you think about it. You don't get good grades just for free - you have to pay the price of studying hard. You can't get strong muscles without putting in the hard work of exercising. Having friends isn't free either; it requires the effort of being kind, loyal, and thinking about others.Here's one more example that really drives the point home for me: Remember last year when I played a bunch of those online games that were "free to play?" Well, I ended up begging my parents for money to buy power-ups, lives, outfits for my characters, and other extras. Pretty soon, those "free" games had cost a small fortune! By falling for their tricks, I learned that there's definitely no such thing as a free lunch...or a free game!When you start looking for it, you see this truth about sacrifice and trade-offs everywhere in life. Even the people who seem to get things for "free" have usually made sacrifices to get there. Professional athletes get paid a lot, but they've spent years of effort training and developing their talents. Famous actors and singers get fancy perks, but they've traded privacy and ordinary lifestyles for their fame and wealth.The more I think about it, the more this lesson of "no free lunch" seems really important. It teaches that anything worthwhile in life has a price. You have to put in the work for whatever you want - whether it's money, success, fitness, or even just a good reputation. If someone's trying to sell you on something being completely "free," you should be wary because there's always a hidden cost somewhere.Instead of looking for freebies, we should appreciate that things have Value and learn to make wise trade-offs. If I want to play more video games, I may have to accept less TV time. If I want to go to an expensive summer camp, I need to earn more through chores or get better birthday gifts. Every choice has a cost, but being mindful of that principle helps me make smart decisions.At the same time, I've learned that some of the best things in life really are "free," at least when it comes to money - things like friendship, laughter, enjoying nature, or family time. But even those have a different kind of price, like making the effort to nurture relationships or skip screen time. Everything has a trade-off, one way or another. There's no such thing as a free lunch!So while the saying seems confusing at first, I've realized it's an important reminder to always be thoughtful about costs and sacrifices. By understanding that universal truth, I can make better choices going forward. Appreciating that nothing is truly free helps me to be grateful, work hard, spend wisely, and value the good things in life that ARE available to everyone through effort and wise trade-offs. It's a simple saying, but powerful advice for living!。
