“唔好同佢一般见识” 的英文？ 同什么人讲这句说话也好 用 idiot (笨蛋、傻瓜) 是冒犯了一点。“一般见识” 是比较含蓄、文雅的用词 英文可以是 shallow 或 superficial。以 ‘shallow" 或 ‘superficial" 形容某人 是指其见识 ‘肤浅"、论据 ‘浅薄"、思想 ‘缺乏深度" lacking deep or serious thinking、 (of knowledge thinking e) not thorough or plete (Longman Dictionary Of Contemporary English)。“唔好同佢一般见识” 可说成：“Don"t be as shallow as he/she is” 或 “Oh don"t be so superficial as he/she is！”。 此外 亦可用 ‘empty-headed" 一词 意思是 ‘愚蠢的"、‘没有头脑的" silly、 pletely lacking the power of serious thought or feeling (Longman Dict. Of Contemporary English) 但较 idiot 客气。“唔好同佢一般见识” 是：Now you don"t want to be an empty-headed fellow like him/her do you?” 唔好 同佢一般见识 Is not good with his / her / their lowers oneself to the same level. don"t be a idiot as he is. ....我谂你系想呢句野同fd讲 我谂你都唔会咁同你d长辈讲架啦..."唔好 同佢一般见识" 你既见识同你长辈d见识唔同.... 参考: me

当你被问及考虑是否上大学的决策中、你的成本是什么呢？大多数人会将学费、生活费、住宿费用加在一起。但这些钱不代表你上一所大学所放弃的东西。第一个问题在于：即使你不上学也依然需要住宿的地方、要吃饭。第二个问题在于：大学四年的时间才是你最大的成本。当你在大学听课、写论文的时候，便无法工作赚钱。大学里的运动员如果退学成为职业运动员、每一年有上百万的收入，此时上学的成本实在太大了。多付出的边际成本能否为我带来大于边际成本的边际收益。理性人明白：生活中的很多决策不是非黑即白的选择，而往往是介于其间的灰色地带；因此理性人通常对比边际收益和边际成本来做决策关键概念。理性人（rational people） ：系统且有目的地尽最大努力实现其目标的人（优秀的人）边际变动（marginal change）：对行动计划的微小增量调整边际成本（margial cost）：没增加一个单位的物品或者服务的生产 需要额外支付的成本边际收益(margial revenue)：每增加单位物品或服务的生产 带来的额外收益

buy在英语中的发音为/bau026a/，其中的“u”发音为/ai/，读音与“by”相似。buy是一个常用的动词，表示“购买，买入”等意思。下面是buy的一些常见用法及其固定搭配：1.buy + 名词buy + 名词表示“购买某物”，例如：I want to buy a new phone.（我想买一部新手机。）She bought a dress for the party.（她为聚会买了一条裙子。）2.buy + 动词不定式buy + 动词不定式表示“购买某种服务或机会”，例如：He bought a ticket to the concert.（他买了一张音乐会的门票。）She bought a membership to the gym.（她购买了健身房的会员资格。）3.buy + 介词短语buy + 介词短语表示“用某种代价或方式购买某物”，例如：He bought the car for $10,000.（他以1万美元的价格买下了这辆车。）She bought the house with a mortgage.（她通过抵押贷款购买了这栋房子。）4.buy + frombuy + from表示“从某人或某地购买某物”，例如：I always buy my groceries from the local market.（我总是从当地市场购买食品杂货。）She bought the book from the bookstore.（她从书店买了这本书。5.除了以上用法外，buy还有一些常见的固定搭配，例如：buy in bulk（批量购买）buy on credit（赊购）buy out（买下全部股份）buy into（购买股份或投资）buy time（争取时间）

华尔兹是舞厅舞中最早的、也是生命力非常强的自娱舞形式，亦称圆舞。“华尔兹”一词最初来自古德文Walzer，意思是“滚动”、“旋转”或“滑动”。华尔兹舞步在速度缓慢的三拍子舞曲中流畅地运行，因有明显的升降动作而如一起一伏连绵不断的波涛，加上轻柔灵巧的倾斜、摆荡、反身和旋转动作以及各种优美的造型，使其具有既庄重典雅、舒展大方、又华丽多姿、飘逸欲仙的独特风韵。它因此而享有“舞中之后”公主小妹 里有 一段 你可以看看

原理一人们面临交易关系原句可理解为"人们面临权衡取舍"。当人们组成社会时，他们面临各种不同的权衡取舍。典型的是在"大炮与黄油"之间的选择，当一个社会的支出更多的运用在保卫海岸线上免受外国入侵的时候(大炮)，用于提高国内生活水平的消费品(黄油)就少了。在现代社会里，同样重要的是清洁的环境和高收入水平之间的权衡取舍。认识到人们面临权衡取舍本身并没有告诉我们，人们将会或应该做出什么决策。然而，认识到生活中的权衡取舍是重要的，因为人们只有了解了他们面临的选择，才能做出良好的决策。原理二某种东西的成本是为了得到它而放弃的东西一种东西的机会成本是为了得到这种东西所放弃的东西。当做出任何一项决策，例如，是否上大学时，决策者应该认识到伴随着每一种可能的选择而来的机会成本。实际上，决策者通常是知道这一点的。那些到了上大学的年龄的运动员如果退学，转而从事职业运动就能赚几百万美元，他们深深认识到，他们上大学的机会成本极高。他们往往如此决定:不值得花费这种成本来获得上大学的利益，这一点也不奇怪。原理三理性人考虑边际量"边际量"是指某个经济变量在一定的影响因素下发生的变动量。经济学家用边际变动(marginal change)这个术语来描述对现有行动计划的微小增量调整，边际变动是围绕你所做的事的边缘的调整。个人和企业通过考虑边际量，将会做出更好的决策。而且，只有一种行动的边际利益大于边际成本，一个理性决策者才会采取这项行动。原理四人们会对激励做出反应由于人们通过比较成本与利益做出决策，所以，当成本或利益变动时，人们的行为也会改变。这就是说，人们会对激励做出反应。 然而，政策有时也会有事先并不明显的影响。在分析任何一种政策时，我们不仅应该考虑直接影响，而且还应该考虑通过激励发生的间接影响。如果政策改变了激励，那就会使人们改变自己的行为。原理五贸易能使每个人状况更好也许你在新闻中听到过，在世界经济中日本人是美国人的竞争对手。实际上，两国之间的贸易可以使两个国家的状况都变得更好。从某种意义上说，经济中每个家庭都与所有其他家庭竞争。尽管有这种竞争，但把你的家庭与所有其他家庭隔绝开来并不会使大家过得更好。通过与其他人交易，人们可以按较低的成本获得各种各样的物品与劳务。原理六市场通常是组织经济活动的一种好方法2014年之前大部分曾经是中央计划经济的国家已经放弃了这种制度，并努力发展市场经济。在一个市场经济中央计划者的决策被千百万企业和家庭的决策所取代。这些企业和家庭在市场上相互交易，价格和个人利益引导着他们的决策。原理七政府有时可以改善市场结果为什么我们需要政府呢?一种回答是，看不见的手需要政府来保护它。只有产权得到保障，市场才能运行。但是，还有另一种回答。政府干预经济的原因有两类:促进效率和促进平等。尽管看不见的手通常会使市场有效地配置资源，但情况并不总是这样。经济学家用市场失灵(market failure)这个术语来指市场本身不能有效配置资源的情况。我们说政府有时可以改善市场结果并不意味着它总能这样。学习经济学的目的之一就是帮助你判断什么时候一项政府政策适用于促进效率与公正。原理八一国的生活水平取决于它生产物品与劳务的能力世界各国生活水平的差别是惊人的。随着时间推移，生活水平的变化也很大。用什么来解释各国和不同时期中生活水平的巨大差别呢?答案是几乎所有生活水平的变动都可以归因于各国生产率(productivity)的差别。生产率与生活水平之间的关系对公共政策也有深远的含义。在考虑任何一项政策如何影响生活水平时，关键问题是这项政策如何影响我们生产物品与劳务的能力。原理九当政府发行了过多货币时，物价上升什么引起了通货膨胀?在大多数严重或持续的通货膨胀情况下，罪魁祸首总是相同的---货币量的增长。当一个政府创造了大量本国货币时，货币的价值下降了。原理十社会面临通货膨胀与失业之间短期权衡取舍当政府增加经济中的货币量时，一个结果是通货膨胀，另一个结果是至少在短期内降低失业水平。说明通货膨胀与失业之间短期权衡取舍的曲线被称为菲利普斯曲线(Phillipscurve)，这个名称是为了纪念第一个研究了这种关系的经济学家而命名的。
