Unit 1 Book 3 Do you remember your first love? All those exciting and wonderful new emotions – the way your heart raced when that special person was near –those anxious, awkward moments when you didn't know what to say or do? And then (for most of us) that sad moment when for one reason or another it all came to an end … Ernest Hemingway once said, "Every love story ends as a tragedy" – but the authors of the texts in this unit have a different point of view. Text A focuses on the unexpected side effects of the author's first venture into romance, while Text B recalls the ups and downs of the author's great love for … his car! Finally, the authors of Text C offer some fascinating advice about how to successfully navigate romantic relationships. Text A How I Got Smart A common misconception among youngsters attending school is that their teachers were child prodigies. Who else but a bookworm, with none of the normal kid's tendency to play rather than study, would grow up to be a teacher anyway? I've tried desperately to explain to my students that the image they have of me as an enthusiastic devotee of books and homework during my adolescence was a bit out of focus. On the contrary, I hated compulsory education with a passion. I could never quite accept the notion of having to go to school while the fish were biting. But in my sophomore year, something beautiful and exciting happened. Cupid aimed his arrow and struck me right in the heart. All at once, I enjoyed going to school, if only to gaze at the lovely face in English II. My princess sat near the pencil sharpener, and that year I ground up enough pencils to fuel a campfire. Alas, Debbie was far beyond my wildest dreams. We were separated not only by five rows of desks, but by about 50 I.Q. points. She was the top student in English II, the apple of Mrs. Larrivee's eye. Occasionally, Debbie would catch me staring at her, and she would flash a smile that radiated intelligence and quickened my heartbeat. It was a smile that signaled hope and made me temporarily forget the intellectual gulf that separated us.

新21世纪大学英语综合教程4 Unit1译文 Harsh Reality of the American Dream 美国梦的严酷现实

美国梦的严酷现实 汉弗莱·霍克斯利 这是西雅图海边阳光明媚、赤日炎炎的一天,穿越海湾能一眼望见远处的岛屿,其自然美景没有受到任何破坏。 人们躺在一片草坪上看书或和恋人相依,一阵充满活力的无伴奏的歌声从草坪的另一端传了过来。原来是一家咖啡馆外面有4位男子正在唱着一首关于丘比特的情歌,每个人都有着不同的音域。围了几圈的人群正摇摆着身体合着节奏拍手。 这家咖啡馆的星巴克徽标让我觉得有一点过时,直到有人提到这是世界上第一家开张的星巴克时我才恍然大悟。 我是因为最近的一次调查来到西雅图的。这项调查是由位于伦敦的经济运转情况中心发起的,旨在了解在世界不同的地方发财致富究竟有多么容易或多么困难——如果不是发财致富,至少也是摆脱贫困。 “如果你生在美国的一个穷人家庭,”其中的一位作者说,“那么比起在欧洲、北欧国家,你更有可能终身贫困,就连在加拿大,一个你觉得和美国差不多的国家,那里的情况也要比美国好。” 机会 这项研究连同伊拉克战争以来愈来愈普遍的反美情绪,让我想到了一个有关美国梦——认为在美国任何事情都有可能实现的想法——的问题。 我之所以选择西雅图不仅仅是因为星巴克诞生在那里,还因为微软、亚马逊图书以及波音飞机都来自这座小城市。如果你愿意将它们称作梦想的话,那么这些小梦想现在已经变成了全球的大品牌。 “天气真不错,是吗?”我转过身来,看到一张布满皱纹、略显疲惫的男人的脸,我称呼他“戴夫”。“你会得到你想要的吗?” 我们几天前见过面,当时他正在一家帮助穷人和无家可归者的慈善机构里吃早饭,我曾问他是否相信美国梦。 “美国梦,”戴夫吃着松饼,用餐巾纸擦了擦嘴说道,“这个嘛,它时来时去。它还会再来的。” 成功者和失败者 在一家天花板很低的餐厅里,有一百来个男人沿着搁板桌并排而坐。 他们5点就开始排队登记了,因为说不定会有工作。然后他们吃饭,而保安则在一边监视他们,以防有什么麻烦发生。 在欧洲或仅仅是边界那一边的加拿大,人们更有可能获得社会保障。但是,这里是美国。在这里,社会被无情地划分为成功者和失败者。 不过,奇怪的是,对于政府的愤恨或指责却很少。美国文化注重的是自力更生与个人奋斗。 “美国梦,”其中一位男子说,他的眼睛炯炯有神,鼻子歪得厉害,一定是在数起斗殴中被打断过多次。“我猜你说的是家、妻子、孩子,以及诸如此类的东西吧。” “这些你有吗?”我说。 “没有,我没有。我曾经有过机会,但我失去了。” 控制 就在马路那边的一家小印刷所里,一位身体健康、若有所思的前空军军官博比·雷·福布斯正在往信封里塞日历。 他的生活因婚姻失败而崩溃。他最终流落街头,不过最近终于找到了一份工作,一直在干。

Unit1 赞美之词的魔力 1、一次,一位百老汇喜剧演员做了一个噩梦:他梦见自己在一个座无虚席的剧场里讲故事、唱歌,数以千计的人们看着他—但是没有人笑或拍手。“即使一个星期能赚10万美元,”他说,“那也像人间地狱一般。” 2、不仅演员需要掌声,没有赞扬和鼓励,任何人都会失去信心。因此,我们都有着双重需求:被别人称赞以及懂得如何去称赞别人。说赞美的话是有技巧的,有正确的说法。比如,因为某些显而易见的成就而去表扬一个人,这不是真正的赞扬。你得运用辨别力和创造力。“您今晚的演讲很精彩、很有说服力,”一次,一位和蔼可亲的女士对一位商人说,“我禁不住想,您肯定也能当一名出色的律师。”听到这意外的溢美之词,那位商人像个男生般地脸红了。 3、无论声名显赫还是默默无闻,没有一个人会对真诚的赞赏无动于衷。耶鲁著名的英语教授威廉·里昂·费尔普斯讲述道:“一个炎热的夏日,我走进一家拥挤的饭馆吃中饭。服务员递给我菜单时,我说,‘今天厨房里的小伙子们肯定在受罪!’服务员惊讶地看着我说:‘来这儿的人都抱怨菜的味道不好,对服务评头论足,还埋怨太闷热。19年了,你是第一个对后面厨房里的厨师们表示同情的人。’人们所需要的,”费尔普斯下结论道,“是作为人能得到一点点关注。”在那种关注中,真诚是至关重要的。当劳作了一天的男人回家时看见孩子们将脸贴在窗上、张望着等待他,他也许会感到这种无声而珍贵的语言如甘露一般涤荡了他的心灵。 4、孩子们尤其渴望鼓励。童年时如果得不到善意的赞赏,将会危及性格的发展。一位年轻妈妈向A·W·比文牧师讲述了一件让人伤心的事:“我的小女儿常常不听话,我不得不批评她。但是有一天,她特别乖,没有做一件会挨批评的事。当天晚上,我给她盖好被子、准备下楼时,听见她在抽泣。我走回去,发现她把头埋在枕头里。她一边呜咽一边问:‘难道我今天还不够乖吗?’” 5、“那个问题,”那位妈妈说,“像把刀一样刺痛了我。当她做错事时,我总是急于纠正,可是当她努力表现得好些时,我却没有注意。我哄她睡觉时连一句称赞的话都没有。” 6、同样的准则——说友善的话——适用于所有的人际关系。我小时候住在巴尔的摩,当时街坊里开了一家新的药店,为此我们那位技能娴熟、资历颇深的药剂师老派克·巴洛很生气。他指责他的年轻对手出售廉价药品而且在配药时没有经验。最后,那位受到伤害的新来的药剂师考虑以诽谤罪起诉对方,于是他去见了一位明智的律师托马斯·海斯。“别把争端扩大化,”海斯建议说,“试试友善(地处理)。” 7、第二天,当顾客们告诉他他的对手在讲他坏话时,这位新药剂师说,一定是哪里发生误会了。“派克·巴洛,”他对他们说,“是这个镇上最好的药剂师之一。他能在任何一刻、任何一天或任何一晚配出急救药方。他的细心是我们所有人学习的榜样。这个街坊已经扩大了—有足够的空间同时容下我们俩。我把他的药店当作我学习的典范。” 8、当那位老人听说这些话时——因为称赞和丑闻一样会长着闲聊的翅膀迅速散播——迫不及待地要亲自见见这个年轻人,给他一些有用的建议。怨恨因真挚诚实的赞扬而化解了。 9、为什么我们大多数人对于那些能让其他人高兴的事实避而不提呢?“给生者一朵玫瑰,其意义远远胜于送给逝者华丽的花圈。”一位风度翩翩的老绅士以前常常顺路去新罕布什尔州靠近康韦的一家古董店里推销商品。有一天,等他走了以后,古董商的妻子说,她很想告诉他他的来访给他们带来了很多乐趣。丈夫回答说:“下一次我们告诉吧。” 10、第二年夏天,一个年轻女子来到店里,她自我介绍说是那个销售员的女儿。她说,她的父亲已经去世了。“从那天以后,”古董店老板说,“不管什么时候当我想到一个人的优点,我就会立即告诉他。也许我不再有另一个机会了。” 11、如同艺术家们在把美展示给别人的过程中能获得满足一样,任何一个掌握赞美艺术的人会发现它对给予者和接受者来说都是一种幸福。它给陈词滥调注入温暖和愉悦,将喧嚣的世界转变成优美的音乐。 12、每个人身上都有值得称道的地方。我们只是需要把它说出来。 Unit2 你当然有创造性 1、对于我们很多人来说,“创造性”一词的周围有一堵墙,我们却在墙外边。我们会申辩说,我们没有那份

玻璃——捕捉光晕的舞步 威廉·埃利斯 长期以来,玻璃以其各种形式高尚地为人类服务。作为使用最为广泛、性能最多样化的人工制造材料,玻璃既可以用来制作如网球场般大的望远镜的镜面,也可以制作又小又简单在地上滚动的弹珠。新技术进一步拓展了这种极具可塑性的材料的用途。长度超过800万英里的玻璃光纤把电话和电视信号传递到五湖四海,玻璃陶瓷可以用来制作导弹的鼻锥体和牙齿的人造冠,玻璃微珠可以对人体的特定器官进行靶向放射治疗,甚至还可以为了清除核废料而把它加工成一种新型的玻璃。 光学计算机即将问世,其工作原理是通过光子(即小型激光发射的脉冲)而不是通过电子来储存程序、处理信息。脉冲通过玻璃纤维而不是通过铜丝传递。光学计算机的运行速度将比如今的电子计算机提高几百倍,储存的信息量也大大增加。如今,由于纤维光学技术的运用,我们能够观察到的物体越来越细微,甚至细菌病毒的内部结构也能一览无遗,所看到的图像也越来越清晰。新一代的光学仪器已经出现,可以详尽地呈现细胞内部的运动。正是纤维光学和液晶显示技术的大量运用,已经拥有15万名员工、总产值达160亿美元的美国玻璃工业不得不新建工厂增加产量以满足市场的需求。 然而,玻璃不仅在技术和商业领域拓宽了用途,起源于古罗马时代的传统—玻璃艺术也繁荣起来。几乎到处可见人们在吹制玻璃工艺品。“1975年之前我没有卖掉过一件玻璃制品,”戴尔·奇休利

微笑着说。然而,经历了低潮期之后,18年前玻璃艺术再现辉煌,如今奇休利成了20世纪最为成功的商业艺术家之一。现在,他又接到了一宗新的活儿,为一家比萨饼公司的总部制作一个玻璃雕塑,这个任务将为他带来50万美元的酬劳。 然而,并不是所有与我们生活相关的玻璃技术都是超现代的。以简单的灯泡为例,在本世纪初,大多数灯泡都是人工吹出来的,一个灯泡的成本相当于一个普通工人半天的报酬。事实上,20世纪20年代康宁公司发明的带式玻璃成型机照亮了全美国,使得灯泡的价格大幅下降。毫无疑问,这项成就被称为人类历史上最伟大的机械发明之一。然而,其工作原理却非常简单:将玻璃熔化成狭窄的液体带状,令它在一根上面有孔的移动的钢条上行进,玻璃液通过小孔流入准备好的模具中,喷出压缩的空气接着把玻璃定型。用这种方式,一台机器一小时可以制作66000个灯泡外壳,而4个吹玻璃工人一天的产量仅为1200个。 玻璃性能多样化的奥秘在于其内部结构。尽管玻璃像固体一样是刚性的,其原子的分布却像液体一样是随意混乱的。在熔化的过程中,原材料中的原子在其分子结构中的正常位置被打乱,而在原子还原到晶体结构的分布之前玻璃就冷却了。这种分子结构的松散性使玻璃具备了如工程师所说的极强的“可塑性”,因此技术人员可以根据需要任意裁剪玻璃。 如今,科学家正继续试验新的玻璃混合材料,建筑设计师则通过使用特殊玻璃继续发挥他们的想象力。伦敦建筑师迈克·戴维斯
