Text1 Habits are a funny thing. We reach for them mindlessly, setting our brains on auto-pilot and relaxing into the unconscious comfort of familiar routine. “Not ch In but habit rules the unreflecting herd,” William Wordsworth said in the 19th century. the ever-changing 21st century, even the word “habit” carries a negative connotation. So it seems antithetical to talk about habits in the same context as creativity and innovation. 习惯是件有趣的事情。我们无意识间养成了一些习惯,我们的大脑是自动运 转的,轻松进入熟知套路所带来的不自觉舒适状态。“这并非选择,而是习惯控 制了那些没有思想的人”,这是威廉?华兹华斯(William Wordsworth)19世纪时 说的话。在现在这个日新月异的21世纪,甚至习惯这个词本身也带有负面涵义。 因此,在创造和革新的背景下来谈论习惯,似乎显得有点矛盾。 But brain researchers have discovered that when we consciously develop new habits, we create parallel synaptic paths, and even entirely new brain cells, that can jump our trains of thought onto new, innovative tracks. But don’t bother trying to kil off old habits; once those ruts of procedure are worn into the hippocampus, they there to stay. Instead, the new habits we deliberately ingrain into ourselves create parallel pathways that can bypass those old roads. 但大脑研究人员发现,当我们有意识地培养新的习惯的时候,我们创建了平 行路径,甚至是全新的脑细胞,可以让我们的思路跳转到新的创新轨道上来。但 是,不必费心试图摈弃各种旧习惯;一旦这些程序惯例融进大脑,它们就会留在 那里。相反,我们刻意培养的新习惯会创建平行路径能避开原来那些老路。 “The first thing needed for innovation is a fascination with wonder,” says D Markova, author of “The Open Mind” and an executive change consultant for Professional Thinking Partners. “But we are taught instead to ‘decide,’ just as decide is to kill off president calls himself ‘the Decider.’” She adds, however, that “to all possibilities but one. A good innovational thinker is always exploring the many other possibilities.” 大学英语

It was not until in my late thirties that I made this important discovery: giving-away makes life so much more exciting. You need not worry if you lack money. This is how I experimented with giving-away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving-away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post-office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation. “Wasn’t it you that wrote us that letter a year ago about delivering a special delivery to your home?” I said yes. “Well, you certainly are going to have a box in this post office if we have to make one for you. You don’t know what a letter like that means to us. We usually get nothing but complaints.” 像绝大部分人,我长大看待生命是一个过程获得。直到我在30月底,我作出这个重要发现:给予,距离使我们的生活如此更令人兴奋的。您不必担心如果缺乏资金。这是我尝试让-消失。如果一个主意,

Unit1 Chapter1 本,查德,布兰卡和朱迪每个月的第三个星期四举行发明家俱乐部会议。他们轮流展示他们的新发明。 明天轮到本展示他的新发明。唯一的问题就是他到现在还没有想出一个发明··· 本正坐在餐桌旁吃着一杯冰淇淋。 “我能做什么呢?”他一边吃冰淇淋一边问自己。 本对自己要发明什么毫无头绪。他吃完冰淇淋,准备再去弄些来。但是,冰淇淋一点也不剩了。 “我知道了,”他兴奋地说,“我要发明一个冰淇淋机!” 词组:hold meeting召开会议 take turns轮流,更替 think of考虑;想起;有···想法 sit at坐,在···坐 a bowl of一碗 have no idea不知道,不了解 Chapter2 本抓起几张纸和支钢笔,然后他就画出了他的冰淇淋机设计草图。这个草图看起来不太像个冰淇淋机,但是本确信它是可行的。 “我不需要试验,”本对自己说,“好吧,我没时间去试验了。” 本只有找材料的时间了。 第二天下午,查德、布兰卡还有朱迪都在本的卧室。本带着一只麻袋出现了。他倒提着麻袋,许多稀奇古怪的东西掉了出来。 “一堆废品,”布兰卡说,“那真是个好发明。” “哈哈,”本说,“你们就等着瞧吧。” 词组:look much like看起来很像 say to oneself暗想,自言自语 turn up开大;翻起;出现 upside down颠倒,倒转;混乱地 fall out争吵;结果;解散;掉队 a pile of一堆 wait and see等着看;拭目以待;观望;走着瞧 Chapter3 本捡起的第一个东西又大又圆,是用钢做的。它是洗衣机的核心零部件。 本举起那部分,看了看底部的洞。 “那个洞是你钻的吗?”查德问。 “是啊,”本说。 “你这个做得不是很好,”查德说。 “只要有用就行了,”本告诉查德。 “你要知道东西也得看上去好才行,”查德说。 接着,本抓起一根软管,把它装入他钻的那个洞里。 “我想我知道这是什么了,”朱迪激动地说,“它是一个鼠窝!” “一个什么?”布兰卡和查德异口同声问道。 “一个鼠窝,”朱迪说,“老鼠通过软管爬进家里。” 朱迪经常说些奇怪的话,但其他人认为这是她说过的最奇怪的事之一。 本在地上放了一个塑料的冰淇淋盒,把软管的另一端放了进去。然后,他拿起一根细绳,把它绕在洗衣机零部件上。 当绳子紧紧地缠绕到零部件外面后,本往后退了退,仔细瞧着他的发明。 “好吧,这是什么?”布兰卡、查德和朱迪一同问道。 “它当然是一个冰淇淋机啦!”本说。 “那它如何工作呢?”查德问。 “它行不通的,”布兰卡说。

Unit 1 Genetically modified foods -- Feed the World? If you want to spark a heated debate at a dinner party, bring up the topic of genetically modified foods. For many people, the concept of genetically altered, high-tech crop production raises all kinds of environmental, health, safety and ethical questions. Particularly in countries with long agrarian traditions -- and vocal green lobbies -- the idea seems against nature. 如果你想在某次晚宴上挑起一场激烈的争论,那就提出转基因食品的话题吧。对许多人来说,高科技的转基因作物生产的概念会带来诸如环境、健康、安全和伦理等方面的各种问题。特别是在有悠久的农业生产传统和主张环保的游说集团的国家里,转基因食品的主意似乎有悖自然。 In fact, genetically modified foods are already very much a part of our lives. A third of the corn and more than half the soybeans and cotton grown in the US last year were the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic is out of the bottle. 事实上,转基因食品已经成为我们生活重要的一部分。根据农业部的统计,美国去年所种植玉米的1/3,大豆和棉花的一半以上都是生物技术的产物。今年,美国将种植6500多万英亩的转基因作物。基因妖怪已经从瓶子里跑出来了。 Yet there are clearly some very real issues that need to be resolved. Like any new product entering the food chain, genetically modified foods must be subjected to rigorous testing. In wealthy countries, the debate about biotech is tempered by the fact that we have a rich array of foods to choose from -- and a supply that far exceeds our needs. In developing countries desperate to feed fast-growing and underfed populations; the issue is simpler and much more urgent: Do the benefits of biotech outweigh the risks? 但是,显然还有一些非常现实的问题需要解决。就像任何一种要进入食物链的新食品一样,转基因食品必须经过严格的检验。在富裕的国家里,由于有大量丰富的食品可供选择,而且供应远远超过需求,所以关于生物技术的争论相对缓和一些。在迫切想要养活其迅速增长而又吃不饱的人口的发展中国家,问题比较简单,也更加紧迫:生物技术的好处是否大于风险呢? The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. And by 2050, the UN estimates, it will probably near 9 billion. Almost all that growth will occur in developing countries. At the same time, the world's available cultivable land per person is declining. Arable land has

Lesson 8 IV. Translation Put the following into Chinese. 1. Every war has had its songs that whipped up patriotic fervor or, in the case of the Vietnam War that encouraged protest against it. 每场战争都有自己的歌曲来唤起人们的爱国热情或者如在越南战争中鼓励人们反战。 2. The idea is to take a song that people like or that has particular meaning or emotional association for them and use it with new words, hoping that some of the liking, meaning, or emotional associations will transfer to the new ideas being communicated. And it often works. 改词是把一首人们喜爱或者对他们具有特殊意义或感情色彩的歌曲填上新词,希望把这种喜爱、意义或感情色彩带到正在传播的新观念中。通常这种方法很奏效。 3 As a result, a number of community and national groups have applied pressure on stations to keep these songs and performers off the air. These charges also stimulated investigations by the Federal Communications Commission, the regulatory agency charged with overseeing broadcast practices. 结果一些社团和全国性团体向电台或电视台施加压力让他们禁播这些演员的节目。这些指控也促使负责广播业的监管机构联邦通讯委员会开始进行调查。 4. Does it mean a station should permit no language or ideas in a song that it would not permit on the news or in a sports program? Or does it mean the station should recognize that different forms of communication or entertainment, or programs designed for different kinds of audiences, should have different standards concerning language and ideas? 这是否意味着在广播电台或电视台播放的歌曲中不允许出现那些在新闻或体育节目中禁止出现的语言和观念?或者这是否意味着电台或电视台应该承认不同的交流或娱乐形式,或是为不同听众设计的节目,在语言和观念上应该具有不同的标准? 5. One author has suggested that popular music also serves a "rite of passage" function for young girls. The teenage singing idols may serve as non-threatening substitutes for actual boys until boys' maturation catches up with that of girls and some semblance of easy boy-girl relationships can be established. 一位作者指出流行音乐也成了女孩子们成熟的标志。在同龄男孩子成长为像女孩子那样成熟并能较容易地与女孩子建立朋友关系之前,少年歌星可能会成为不会对女孩子形成威胁的男友的替身。 V. Oral Practice and Discussion 1. How was music used during World War II and during the Vietnam War? 2. Describe peacetime uses of music. 3. List the major effects and functions of music. 4. Identify the basic issues in the FCC regulatory position. 5. What problems do you foresee in the development of record labeling plans? 6. Adaptation of popular or favorite songs is a persuasive tactic. Where is this technique used today? Cite several examples. (Hint: Advertising commercials) 7. If music shapes our perceptions and attitudes, then, should we be forced to listen to music in public places such as restaurants and shopping malls? 8. Are there other effects of music not included in this article?
