水恩，乃幸福之源也。鱼离不开水，人离不开亲人和朋友，当你处于逆境和灾难时，帮助你一臂之力，渡过难关的人，都是你的亲人和朋友。吃水不忘挖井人，度过苦难，不能忘记援助过你的人。知恩图报，善莫大焉。

一个人要想获得幸福，必须懂得感恩。生活需要一颗感恩的心来创造，一颗感恩的心需要生活来滋养。

一饭之恩，当永世不忘。顺境里给你帮助的人，不能全部称作朋友，但是能够在你逆境时依然愿意援助你，走出困境的人，一定是你要用一生去感谢和珍惜的人。

唐代李商隐的《晚晴》里有这样一句诗：天意怜幽草，人间重晚晴。久遭雨潦之苦的幽草，忽遇晚晴，得以沾沐余辉而平添生意。

当一个人闯过难关的时候，一定要记住那些支撑你，陪你一起走过厄运的朋友和亲人，这个世界谁也不亏欠谁，帮你是情分，不帮你是本分。如古人所说：淡看世事去如烟，铭记恩情存如血。

学会感恩父母养育之恩，学会感恩朋友的帮助之情，生活里做一个有情有义的人。

你要知道，父母，永远是你最亲近的人，是最爱你的人，不管他们的方法怎么错误？可是爱你的心，都是一样的。千万不要因为自己一时的私心，而忘记感恩。

我们常常希望别人都对自己有情有义，可是想得到别人你真情，首先你必须先付出真情。你帮助别人，不要记在心里，别人帮助你，你要懂得感恩和感动，而不是当做理所当然。

你要知道别人帮你是情分，不帮你是本分。侍父母，要孝顺，对朋友，要真诚。不管你生活的精彩或者混沌，孝顺父母，颐养天年。

一父养十子，十子养一父。在这个美好的时代，中华很多的美德都在逐渐消失，做子孝为天，但是总有一些人，自己活在天堂，硬生生的把父母扔进地狱。

鱼知水恩，乃幸福之源也。鱼离不开水，人离不开亲人和朋友，当你处于逆境和灾难时，帮助你一臂之力，渡过难关的人，都是你的亲人和朋友。吃水不忘挖井人，度过苦难，不能忘记援助过你的人。知恩图报，善莫大焉。

科技英语综合教程课后答案句子翻译整理,刘爱军, Unit1 搏弈的实质是搏弈者采取策略之间的相互依赖性。这种策略性的相互依赖表现为两个不同的类别:连续策略之间的相互作用以及联立策略之间的相互作用。 当我们把博弈的结果表述为一种均衡的时候,并不是基于以下的假设:即博弈的每个参不者的个人最佳策略将会带来共同的最优化结果。 在一些冲突中,任何规律性的行为都会被对手发觉并利用。因而,通过采取混合性策略来迷惑对手就显的非常重要。我们可以从体育运劢中找到一些典型的例子,比如足球运劢中的特定情冴下选择跑位还是传球,网球比赛中选择击打近网球还是底线球。 边缘化策略就是故意使局势变的无法控制的策略,正是由于局势的无法收拾可能令其他对手难以接受,从而迫使对手作出妥协。 当博弈的一方掌握其他各方不了解的信息时,他会急于隐瞒这一信息(例如纸牌游戏中抽到的牌),其他情冴下他也可能想把信息令人信服的公布出来。这两种情冴下,一个基本的原则就是行胜于言。

Unit 1大规模研究发现：地球的“健康”每况愈下 有史以来对地球进行的最大规模的科学分析结果表明，地球上的许多生态系统都达不到标准。 由联合国主持的《千年生态系统评估综合报告》指出，由于不可持续的使用，地球上将近三分之二的用来维持生命的生态系统（包括干净的水源、纯净的空气以及稳定的气候）正遭受破坏。 以上大部分的破坏都是人类在过去的半个世纪里造成的。据报告分析，随着人类对食物、淡水、木材、纤维以及燃料等资源的需求日趋激增，环境发生了极大的变化，引发了诸如滥伐森林、化学污染等问题。因此，该报告的作者警告说，照此下去，本已岌岌可危的生态环境将会在21世纪的上半叶进一步恶化。 这项历史性的研究由来自世界95个国家的政府部门以及民间组织的1,300多位科学家共同完成。四年来，他们考察了地球上许多生物的生长环境、物种以及将他们联系起来的生态体系。联合国环境规划署对该报告进行了编辑整理并于昨天在中国北京公布了研究结果。 在公布该报告的新闻发布会上，联合国秘书长科菲·安南指出：“只有了解环境及其运作过程，我们才能制定出必要的措施加以保护它。”他还说，“只有珍惜所有宝贵的自然资源和人类资源，我们才有希望去建设一个可持续发展的未来。” 对社会经济的影响 该报告对自然界的大部分生物多样性持悲观态度，地球上可能有10%—30%的哺乳动物，鸟类以及两栖动物濒临灭绝。 这次大规模生态调查是根据安南的《千年发展目标》展开的，该发展目标是由联合国发起的，旨在2015年之前大幅减少饥饿与极度贫困等社会经济问题。 总部位于内罗毕的联合国环境规划署执行主席克劳斯·托普弗说：“从某些方面来说，《千年生态系统评估综合报告》让我们首次认识到生态系统服务功能的经济价值，并使我们对尊重和保护地球生命维护系统有了新的见解。” 目前由于人类社会对地球环境的开发利用，食物供应不断增加，然而增长的速度仍然太慢，难以完成联合国制定的在2015年之前消除全球一半饥饿人口的目标。 报告还说，过度使用生态系统的负面影响还包括渔业的衰退，含有大量沉积物的河口周围近海“死亡区”的出现，水质的变化以及不可预测的区域性气候等。 此外，森林的滥伐和其他生态系统的巨大改变也加剧了诸如疟疾、霍乱等疾病的传播，并使已有传染病分化出新的类别。

关于朗文国际英语教程的教材评估

对外汉语2班常晓晓 1115010203 关于《朗文国际英语教程》（side by side）的教材评估 一、教材简介： 《朗文国际英语教程》(Side by Side)是在亚洲地区销量突破1800万册的美式英语教程，是一套面向青少年学生的初级至中高级英语教材。这套教材包括一至四册的学生用书以及配套的练习册、教师用书、游戏手册、听力教材、可视教材、图片册和测验题集。全书以语法和功能为核心，教学活动均通过引导式会话练习展开，后面附有读、写、听、发音、分角色扮演和讨论等多项配套练习，以强化和扩展之。 二、教材编写的指导思想： 本套教材旨在为英语学习者提供积极互动的交际型语言学习途径，通过引导会话的方式，帮助学生运用精心策划的语法结构进行会话，并鼓励他们突破课本局限，自行组织会话。课文中的语言练习旨在促进学生之间的对话交流，让他们能够面对面地练习对话。 三、教材编写基本原则： 1、针对性原则。 这套教材针对拥有初级至中高级英语水平的英语学习者，也就是我们小学以及初中水平的学习者。鉴定此教材可以在非目的语环境学习，自学意义不大（无法互动啊），课堂教学为宜，适合长期英语学习者（一至四册难度渐高，不同阶段用不同教材），故较好适合了学习者的学习环境与学习条件。以语法为核心，以对话来巩固，通过听、说、读、写不同方式来展开（这种结构好普遍），培养学习者形成良好的学习习惯与学习方法；课文内容以生活现状为素材，如第一课“What Do You Like to Do on the Weekend?”以时态为主要语法点，配以卡通人物形象，迎合了学习者的学习兴趣与学习动机，很好滴适合了学习者的目标需求和学习需求。此外，教材中课文里的注释、课后的练习以及总结（Chapter Summary）充分而恰当地体现了教学的重点与难点。 2、科学性原则。 从内容上来看，这本书编者是Steven J.Bill Bliss，其英语的纯正性以及语音、语法、词汇的规范性一定程度上可以保证（我是这样认为的）。课文中对语法的阐释与运用很标准，口语与书面语有清晰的界限，同时难易适度、难易均匀。从另一个角度来看，这本书可以畅销亚洲1800万册，内容的规范性毋庸置疑。
