1 While some studies have suggested that frequent use of cell phones causes increased risk of brain and mouth cancers, others have found no such links. But since cell phones are relatively new and brain cancers grow slowly, many experts are now recommending taking steps to reduce exposure.

by bruce stutz

一些研究显示,经常使用手机会增加得脑部和口腔癌症的几率。有的研究却没发现两者之间有什么联系。但是,手机算是个新兴事物,而脑癌发展也缓慢,许多专家还是建议减少使用手机。

2 Does your cell phone increase your risk of brain cancer? Does it affect your skin or your sperm viability? Is it safe for pregnant women or children? Should you keep it in your bag, on your belt, in your pants or shirt pocket? Should you use a hands-free headset? Are present cell phone safety standards strict enough?

手机会增加得脑癌的几率吗?会不会影响皮肤或者精子活性?使用手机对孕妇或孩子安全吗?应该把手机放在哪,包里、衣服口袋,还是挂在腰带上?打电话的时候要用耳机吗?现在的手机安全标准够不够严?

3 You don’t know? You’re not alone.

你不知道?这很正常。

4 With some 4 to

5 billion cell phones now in use worldwide and hundreds of studies seeking evidence of their health effects published in peer-reviewed journals over the last 10 years, there’s precious little scientific certainty over whether cell phones pose any danger to those using them. For nearly every study that reports an effect, another, just as carefully conducted, finds none. All of which leaves journalists, consumer advocates, regulatory agencies, politicians, industry spokespersons, and cell phone users able to choose and interpret the results they prefer, or ignore the ones they don’t.

如今,全世界共有40-50亿手机正在使用。过去十年里,成百上千的研究也在致力于寻找手机影响健康的证据,并在相关刊物上发表论文。但还没有确凿的证据能证明,使用手机损害健康。几乎没有研究发现手机对健康有不良影响。但这还是没影响到政治家、新闻记者、管理机构、产业发言人、消费者保护团体,还有消费者自己,选择他们喜好的结果去理解,忽略不喜欢的那些。

5 Do you, for instance, cite the studies that report adverse effects on sperm viability and motility, due to exposure to cell phone radiation or the studies that showed no —or mixed —results?

6 Do you cite the 2001 study that found increased incidence of uveal melanoma (a cancer of the eye) among frequent cell phone users, or the 2009 study by the same authors that, in reassessing their data, found no increase?

2001年的研究显示,常用手机的人患葡萄膜黑色素瘤(一种眼内癌症)几率会增大。2009年这些研究员又发表报告称,他们再分析当年的数据时,又不能确

定几率是否真会增大。你是否也引用了以上结果呢?

7 Do you cite the Israeli study that found an association between salivary gland cancer and heavy use of cell phones or the Swedish study that found none?

以色列科学家发现唾液腺癌和经常使用手机有一定联系,瑞典科学家门确没得出这个结论。你是否还引用过这些?

8 Do you parse the data and report only those results that have found effects —no matter how small —without citing studies that found no effects? In its much-cited review of cell phone studies, the Environmental Working Group has done just that, reporting, for instance, that “a study from the University of California, Los Angeles, found a correlation between prenatal exposure to cell phone radiation and behavioral problems in children.”But the group left out the study’s very next sentence acknowledging that the association may be “noncausal and may be due to unmeasured confounding.”

你是不是只引用发现不良影响的研究报告,不管其影响多么微乎其微?而从来对没发现不良影响的研究视而不见?环境工作小组就在关于手机的报告中引用了许多负面结论,例如:洛杉矶加州大学的一项研究发现胎儿受到手机辐射和长大后的行为问题有关。但这个研究组在下一句中接着又承认这种关系可能“并没有因果关系,而且也许是其他因素共同作用造成的”。

9 The effects of cell phones have proven difficult to assess because they are relatively new, the way and the amount they’re used continues to evolve, and the problems that cell phones might cause are hard to detect. Brain cancers, for instance, are very rare cancers. They affect only some 18 out of every 100,000 people. But the fact that there’s been no recent increase in the numbers may be meaningless with regard to cell phone use since brain cancers are very slow-growing.

众所周知,手机的影响很难估计。因为手机还是个新鲜事物,人们使用手机的方式和数量也在不断改变,所以这个作用就很难检测。举个例子,脑癌,这是一种很少见的癌症。十万人但中只有18个人可能患脑癌。事实上,最近几年,这个比例并没增长,这说明手机的使用和脑癌并没有因果关系。

10 Cell phones produce “non-ionizing”radiation, which, unlike X- or gamma rays, doesn’t damage DNA by stripping away electrons from molecules in cell tissue. Radiofrequency energy does, however, produce heat and, at high enough levels, can damage cell tissue. This, in the late 1990s, The question is whether safety standards are sufficient to protect against long-term exposure.prompted the U.S. Federal Communications Commission (FCC) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) in Europe to set limits on cell phones’Specific Absorption Rate (SAR) —the measure of the amount of radiofrequency energy a cell phone user absorbs —at, respectively, 1.6 and 2.0 watts per kilogram. The question remains, however, whether these standards are sufficient to protect against long-term exposures and whether the buildup of heat in cell tissues is more damaging where there’s less blood flow to dissipate it, such as the outer ear, brain,

skin, or testes.

手机产生“非电离”辐射,它不像X或伽马射线那样从细胞组织中的分子里分理出电子,从而破坏DNA。但高频能量确实产生热量,而且当频率足够高时能破坏细胞组织。以上结论是上世纪九十年代末,由美国联邦通讯委员会(FCC)与欧洲的国际非电离辐射保护委员会(ICNIRP)提出,为了限制手机辐射吸收率(SAR)(即每个手机用户使用电话时吸收的高频能量多少),前者规定最高不能超过1.6瓦特/千克体重,而后者为2.0瓦特/千克体重。这就给我们留下了一些问题:这些标准到底能不能有效保护人们免受长期辐射?是不是当细胞组织(如外耳、大脑、皮肤和睾丸)中血量不够分散热量时,其本身积累的热量破坏性更大?

11 The exposure standard has been the subject of Congressional hearings. Consumer groups have warned that children may be more susceptible to radiofrequency heating effects than adults. U.S. Congressman Dennis Kucinich introduced a bill for a federal research program on the effects of cell phone radiation that also calls for a label warning users about potential links between long-term use and cancer.

辐射量标准已经成为议会听证会的议题。消费者被告知,儿童比成人更容易受到高频热效应的影响。美国议员Dennis Kucinich提出一项议案,即设立一个联邦项目,研究手机辐射的影响,并号召以后再手机上标示出“长时间使用手机与癌症有潜在关系”之类的标语,警告消费者。

12 Last month, San Francisco passed a “Cell Phone Right-to-Know”law that requires manufacturers to post in stores each cell phone’s Specific Absorption Rate. In response, CTIA-The Wireless Association, which represents the wireless communications industry, filed suit July 23 in U.S. District Court in San Francisco to block enforcement of the new law. It cites the U.S. Food and Drug Administration’s (FDA) statement that “the weight of scientific evidence has not linked cell phones with any health problems.”

上月,旧金山通过了一项“手机知情权”法律,要求生产商在销售店明确标示每一部手机的辐射吸收率。同时,代表无线通讯产业的美国无线通讯协会,于7月23日在美国地方法院提出反对诉讼,阻止这项新法律的实行。其引用了美国食品与药物管理局(FDA)的报告“现有科学证据不足以证明手机与任何健康问题间存在联系”。

13 So far, the National Cancer Institute stands by the FDA. And neither the FCC nor the ICNIRP has recommended any changes in their present standards until there’s clear scientific evidence to demonstrate they need changing.

美国国家癌症研究所支持食品与药物管理局的结论。联邦通讯委员会与国际非电离辐射保护委员会也表示,在未有清楚科学依据证明现有标准需要变动前,他们将维持此标准。

14 That kind of clarity may be a long way off.

不过这些清楚科学证据似乎离我们还很远。

15 Take, for example, the findings released in May of INTERPHONE, the largest

and longest study ever conducted on whether —and by how much —cell phone use increases the odds of developing brain cancer. Carried out by the International Agency for Research on Cancer —at a cost of some $25 million and nearly 10 years in the making —the study involved roughly two dozen scientists and research teams from around the world and some 10,000 patients and cell phone users from 13 countries. The study’s epic scope, however, only made its meager conclusions seem all the more unsatisfying.

以INTERPHONE研究五月份发表的结论为例子。这是目前规模最大持续时间最长的研究,针对手机会不会增大使用者患脑癌的几率,且会在多大程度上影响。由国际癌症研究署(IARC)主持,耗资2500万美元,历时十年。共有世界各国的约24位科学家和研究团队参与,涉及来自13个国家的一万多名患者和手机用户。研究对象范围虽然很广,但结论还是太缺乏说服力。

16 “Overall, no increase in risk of glioma [a cancer of the cells that protects the brain’s neurons] or meningioma [tumors that develop in the tissue that surrounds the brain] was observed with use of mobile phones,”the study concluded. “The possible effects of long-term heavy use of mobile phones require further investigation.”

研究结论是:“总体来看,手机用户患神经胶质瘤(神经胶质是保护大脑神经的一种细胞)和脑膜瘤(脑膜是大脑周围的组织)的风险不会增加。长时间大量使用手机可能造成的影响,需要进一步研究。”

17 And yet even these modest claims proved contentious. The study scientists themselves recognized problems in the methodology: While they had good data on the participants’tumor and cancer histories, they had very suspect ‘After 10 years of research, we do not have an answer whether mobile phone radiation causes brain cancer,’says one expert.data on their cell phone usage. Participants’recall of how often and how much they talked on their cell phones, when checked against their actual cell phone records, in some cases proved very unreliable. The matching of patients with control subjects also turned out to be problematic. Should controls include only those who never used a cell phone and exclude those who’d used one only infrequently? While the distinction may seem insignificant, such selection biases can wreak statistical havoc. The analysis using the first group, for instance, resulted in the somewhat astonishing finding that regular users of cell phones had a reduced risk of developing glioma.

但这一谨慎的结论颇具争议。参与的科学家发现了研究方法的缺陷:虽然他们在参与者肿瘤及癌症病史方面的数据比较准确,但对于患者手机使用情况的数据就很难保证了。使用情况方面主要通过病人自己回忆他们打手机的频率和时间长短,但有时在查询他们的手机实际通话记录时,病人的回忆也很不可靠。用来对照研究结果的非手机用户组数据也有问题。这一组是不是应该只研究从来不用手机的人,而把极少用手机的人排除在外呢?虽然这一差别看起来对研究结果影响不大,但实际上这种选择误差会破坏数据的准确性。例如,只选从不用手机的参与者的数据分析,竟然发现经常使用手机的用户患神经胶质瘤的几率低!

18 No one was surprised, therefore, that divisions appeared over interpreting the

study’s results. These delayed its release for four years. The raw data, in fact, showed that “long-term heavy use”—that is, talking on a cell phone for 30 minutes a day for 10 years —increased the odds of developing glioma by 40 percent. The question was whether this result was subject to the same selection bias as that which strangely showed a reduced risk among regular users. The final decision was that the findings with regard to the “effects of long-term heavy use”were, while worth “further investigation,”too unreliable to conclude they represented a clear and irrefutable increased risk.

因此,大家也没感到惊讶,这种分组方法显然过度解释了研究结果。所以,研究结果的发布推迟了整整四年。其实,原数据表明,“长时间大量使用”手机(即每天打电话30分钟以上,保持10年),将导致神经胶质瘤的发生几率提高40%。但问题是,这一结果是否与之前经常使用手机的用户患病几率降低的结论一致呢?最后他们决定,针对“上时间大量使用的影响”,若下结论说其会增加患病几率则太没说服力,需要“进一步研究”。

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,

A “Key Player” is a phrase that I've heard about from employers during just about every search I've conducted. 几乎每次进行调查时,我都会从雇主们那里听到“核心员工”这个名词。 I asked a client —a hiring manager involved in recent search — to define it for me. 我请一位客户——一位正参与研究的人事部经理,给我解释一下。 “Every company has a handful of staff in a given area of expertise that you can count on to get the job done. “每家公司都有少数几个这样的员工,在某个专业领域,你可以指望他们把活儿干好。 On my team of seven process engineers and biologists, I've got two or three whom I just couldn't live without,” he said. 在我的小组中,有七名化工流程工程师和生物学

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

Text 1 如果你打算在2006年世界杯锦标赛上调查所有足球运动员的出生证明,那么你很有可能发现一个引人注目的巧合:优秀足球运动员更可能出生于每年的前几个月而不是后几个月。如果你接着调查世界杯和职业比赛的欧洲国家青年队的话,那么你会发现这一奇怪的现象甚至更明显。 什么可以解释这一奇怪的现象呢?下面是一些猜测:a)某种占星术征兆使人具备更高的足球技能;b)冬季出生的婴儿往往具有更高的供氧能力,这增加了踢足球的持久力;c)热爱足球的父母更可能在春季(每年足球狂热的鼎盛时期)怀孕;d)以上各项都不是。 58岁的安德斯?埃里克森是佛罗里达州立大学的一名心理学教授,他说,他坚信“以上各项都不是”这一猜测。在瑞典长大的埃里克森,一直研究核工程,直到他认识到,如果他转向心理学领域,他将会有更多机会从事自己的研究。他的首次试验是在大约30年以前进行的,与记忆相关:训练一个人先听一组任意挑选的数字,然后复述这些数字。“在经过大约20小时的训练之后,第一个试验对象(复述)的数字跨度从7个上升到20个,”埃里克森回忆说。“该试验对象不断进步,在接受大约200个小时的训练后,他复述的数字已经达到80多个。” 这一成功,连同后来证明的记忆本身不是遗传决定的研究,使得埃里克森得出结论,即记忆过程是一种认知练习,而不是一种本能练习。换句话说,无论两个人在记忆力能力上可能存在怎样的天生差异,这些差异都会被每个人如何恰当地“解读”所记的信息所掩盖。埃里克森确信,了解如何有目的地解读信息的最佳方法就是一个为人所知的有意练习过程。有意练习需要的不仅仅是简单地重复一个任务。相反,它包括确定明确的目标、获得即时的反馈以及技术与结果的浓缩。 因此,埃里克森和他的同事开始研究包括足球领域在内的广泛领域中专业执行者。他们收集了能够收集的所有资料,不只是表现方面的统计数据和传记详细资料,还包括他们自己对取得很高成就的人员进行的实验室实验结果。他们的研究得出了一个非常令人惊奇的结论——我们通常称为天分的特征被高估了。或者,换句话说,专业执行者――无论是在记忆还是手术方面,在芭蕾还是计算机编程领域――几乎总是培养的,而不是天生的。 21. 文中提到足球运动员中的出生现象是用来__________. A 强调职业训练的重要性 B 聚焦世界杯上的足球巨星 C 引出什么决定了杰出表现这个话题 D 解释为什么一些足球队比其他足球队表现好

研究生英语系列教材综合教程(上)课文翻译 Unit 1 核心员工的特征 1核心员工究竟是什么样子的?几乎每次进行调查时,我都会从雇主们那里听到“核心员工”这个名词。我请一位客户——一位正参与研究的人事部经理,给我解释一下。“每家公司都有少数几个这样的员工,在某个专业领域,你可以指望他们把活儿干好。在我的小组中,有七名化工流程工程师和生物学家,其中有那么两三个人是我赖以生存的,”他说,“他们对我的公司而言不可或缺。当请你们公司替我们招募新人的时候,我们期待你们会去其他公司找这样的人:其他公司经理不想失去的员工。我们只招募核心员工。” 2这是一段充满了鼓动性的谈话,目的是把猎头们派往竞争对手的公司去游说经验丰富的员工们做一次职业变更。他们想从另一家公司招募核心员工。然而,每家公司也从新人中招人。他们要寻找的是完全一样的东西。“我们把他们和公司顶级员工表现出的特质进行对照。假如他们看起来有同样特征的话,我们就在他们身上赌一把。”只是这样有点儿冒险。 3“这是一种有根据的猜测,”我的人事经理客户说。作为未来的一名员工,你的工作是帮助人事部经理降低这种风险,你需要帮助他们认定你有潜力成为一名核心员工。 4特征1:无私的合作者 职业顾问和化学家约翰·费策尔最早提出了这个特征。关于这个特征,人们已经写了大量的文章。它之所以值得被反复谈及,是因为这一特征是学术界和企业间最明显的差别。“这里需要合作,”费策尔说,“企业的环境并不需要单打独斗,争强好胜,所以表现出合作和无私精神的员工就脱颖而出了。在企业环境中,没有这样的思维方式就不可能成功。” 5许多博士后和研究生在进行这种过渡的过程中表现得相当费力。因为生命中有那么长一段时间他们都在扮演一个独立研究者的角色,并且要表现得比其他年轻的优秀人才更出色。你可以藉此提高在公司的吸引力:为追求一个共同的目标和来自其他实验室和学科的科学家们合作——并且为你的个人履历上的内容提供事迹证明。这个方法,加上你在描述业绩时开明地使用代词“我们”,而不是“我”,能使公司对你的看法从“单干户”转变成“合作者”。更为有利的是,要在你实验室内部,以及在和你们实验室合作的人们之间,培养一个良好声誉:一个鼓励并发动合作的人——还要保证让那些会接听调查电话的人们谈及你的这个品质。 6特征2:紧迫感 唐-豪特是一位给aaas.sciencecareers@org 网站论坛频繁写稿的撰稿人。他之前是一名科学家。许多年前他转向了企业,并一直做到高级管理的职位。他在3M公司一个部门负责策略和商业开发工作,这个部门每年上缴的税收高达24亿多美元。他就是一个重视紧迫感的人。 7“一年365天,一周7天,一天24小时,生意始终在进行,那意味着一年365天,一周7天,一天24小时,竞争也同样在进行,”豪特说,“公司取胜的方法之一就是要更快地到达‘目的地’。这就是说,你不仅要把所有能支持公司快速运转的功能都调动起来,而且还得知道如何决定‘目的地’是哪里。这样,不仅对那些行动快速的人们,也对那些思维敏捷,并有勇气按自己的想法行事的人们都提出了要求。这需要全公司各部门的运作,而不仅仅是管理部门的工作。” 8特征3:风险容忍度 企业要求员工能承受风险。“一名求职者需要表现出仅凭不准确、不完整的信息就做出决策的能力。他或她必须能接纳不确定因素并冒着风险做出结论,”一位客户在职业描述中写道。 9豪特赞同这一说法。“商业成功通常有这样一个特质:那就是能接受不确定因素和风险——个人的,组织上的和财务上的。这就让许多科学家感到不适应,因为学术上的成功其实是依靠认真而严谨的研究。更进一步说,伟大的科学常常是由找寻答案的过程和答案本身两者同时来定义的。因此科学家们往往沉迷于过程。在企业里,你需要了解过程,但最终你会迷上答案,然后根据你认为该答案对你的企业所具有的意义来冒风险。像这样敢冒风险是一套技能组合,是所有雇主在他们最好的员工身上所寻找的东西。” 10风险容忍度的另外一个要点是求职者对失败的承受度。失败很重要,因为这表示你不怕冒险。所以各家公司总会寻找有可能犯错误并敢于承认错误的求职者。大家都知道如何谈论成功——或者当他们在寻找工作的时候应该知道。但很少有人乐意谈论失败,更少有人知道如何从失败的边缘吸取教训和获得经验。“对我的企业来说,求职者需要坦然地谈论他或她的失败,而且他或她需要有真正的失败经历,而不是特意为面试而杜撰的东西。如果做不到的话,那么这个人冒的风险还不够,”豪特说。 11特征4:善于处理人际关系 瑞克·李奇在迪科德遗传工程公司从事业务拓展。李奇最近才转行到企业,做业务方面的工作。我向他咨询这个重要特征,是因为在他的新业务角色中,人际沟通能力在成功和失败之间发挥着很大的作用。“科学家毕生都在积累知识,培养技术上的敏锐感,”他说,“但为企业工作需要完全不同的东西——人际交往的能力。想转行到企业界的科学家们必须优先考虑他们的社会关系资源而不是技术资源。对一个以前一直根据专业知识水平被评价的人来说,突然之间要根据他的人际交往能力来评价他,真是十分令人恐惧。” 12然而,如果认为只有像李奇那样的生意人才需要熟练的人际沟通技巧,那就错了。事实上,我所遇见的在企业工作的核心费工们之所以取得成功,很大程度上是因为他们能够与公司上下各种各样的人共事。 Unit 4 爱和情感连系 1爱,对于人类的生存是不可或缺的。它既是一种情感,又是一种行为。家庭通常是我们最早和最重要的爱和

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

Unit One 旅行通用语 1 数十年来,法兰西语言研究院一直捍卫着法语的尊严。几年前,由于法国人对英语词汇的入侵非常敏感,该机构颁布了净化法语的法律,其内容甚至涉及专业术语。就拿波音747 (Boeing747)来说吧,现在法国人必须用法语词gros-porteur;表示出租的leasing也变成了credit-bail。此类例子不胜枚举,触及生活的方方面面。法国总统希拉克很可能会继续加大力度,直至连英特网internet和字节流(信息组)byte stream之类的词也找到相应的法语新词。哎,真不知未来的法语会变成什么样。 2 不幸的是(或许并非不幸),英语没有受到如此的保护。在美国,随处可见严重偏离英国标准英语的美式英语。“honour”普遍被写成“honor”,“night”也变成了“nite”。许多词意广为人知的英式英语单词被赋予新的解释,交流也变得有些困难。比如说,汽车的行李箱“boot”变成了“trunk”(一个在英国指代树干的单词);引擎盖“bonnet”变成了“hood”(英式英语中的风帽);老式婴儿尿布“nappy”变成了“diaper”(英式英语中的菱格花纹织物);婴儿小外套“matineejacket”也变成了“vest”(英国的内衣汗衫)。显而易见,两国英语曾同出一源,而如今却将两国彼此隔离。当然了,按美国人的观点,是英国人的语言表达出了问题。 3 实际使用中,甚至还有更糟的英语呢!只要你在外国旅游并注意一下菜单、海报、旅店、甚至当地日常生活中的英语,就可以证明过去的标准用语在这些地方已变得不伦不类,让我详例如下: 4 旅行作家波洛?菲利浦曾不惜笔墨地渲染自己的几番经历,我觉得该有更多的读者了解一下。他提及某份荷兰的灯泡目录,上面对用户承诺有“a speedy execution’——快速处死(毫无疑问,想表达的应是“送货及时”)。此外,东柏林的一个衣帽间告示要求客人“please hang yourself here”——请在这儿吊死自己(本想说的是“将衣帽挂在这儿”)。只希望没人会真的从字面上去理解。 5 我还可以补充一些多年周游世界时的亲身经历。例如,奥斯坦德的一家精品店正在宣扬其货品立意新颖,却用了“revolting new ideas”,即“令人作呕的立意”。孟买的几家糕饼屋也鼓吹自己是“No.1 loafers”,目口头号游手好闲者,可是其本意是要宣称自己的糕饼全市第一。 6 我并不知道基督教影响如此之广,直到我在香港看到一位牙医的宣传:“我们由最新的循道宗信徒拔牙”,这儿的“Methodists”(循道宗信徒)显然应改为“methods”,即“方法”。 7 恐怕没人能确定这些误用实际上是体现了英语的普及还是仅仅反映了局限于地方的习惯用法。但可以确定的是,海法医学会绝对应该阻止其会员挂这样的铜招牌:“妇女及其它疾病的专家”。 8 看来旅店对多语种告示颇为青睐,希望它们会有利于人们更好地使用现代化设施。没有它们,旅店就会显得沉闷而缺乏效率。然而,在布鲁塞尔的一家旅店中,这条电梯告示只会令毫无防范的房客更愿意爬楼梯:“使用电梯时,请按要去楼层的按钮。若更多人进入电梯,请分别按各自要去楼层的按钮。电梯会按楼层的字母顺序,依次送客。没复位的按钮显示着接收到的要去楼层的指令”。伊斯坦布尔的一则旅店告示则没这么复杂:“想要客房服务时,请开门喊叫‘客房服务’”。至少那儿的客人不用对付也许经常失灵的电子设备。 9 在土耳其,人们对于“直言不讳”的喜爱在一个已远近闻名的安卡拉导游册中得到了充分体现。导游册这样招揽顾客:“来我们餐馆吧,你会在欧洲救护车中享用中东风味美食”(显然这儿的救护车“ambulance”应为氛围“ambience”)。而另一家瑞士餐馆的菜单也同样吸引人:“我们的葡萄酒绝人他念”。(“our wines leave nothing to hope for'’一语双关,可本意显然是“我们的葡萄酒美味绝伦”)。 10在东欧,奥匈帝国时期的老牌大旅馆从未放弃过礼节。一则旅馆房间告示上写着“诚邀尊贵的客人在12点到14点之间占客房女服务员的便宜”(take advantage of t he chambermaids)。然而,这可能造成意外的交通阻塞。最近的一次莫斯科画展也未必能让偶尔光顾者欣然前往,根据其告示,“画展将展出俄罗斯艺术家的300幅作品,他们中的大部分人在过去十年中已被处死了”。 11 曼谷一家洗衣房的广告词邀请来访的顾客“留下你的衣服,尽情享受吧!”就像是鼓励人们在这座远东娱乐首府干些出格之事。

Passage1 Reading leadership literature, you’d sometimes think that everyone has the potential to be an effective leader. 读领导文学,你有时会认为每个人都有可能成为一个有效的领导者。 I don’t believe that to be true. In fact, I see way fewer truly effective leaders than I see people stuck in positions of leadership who arc sadly incompetent and seriously misguided about their own abilities. 我不相信这是真的。事实上,我认为真正有效的领导者的方式比我看到的人都陷在领导的职位上,遗憾的是他们自己的能力不称职,严重误导了他们。 Part of the reason this happens is a lack of honest self-assessment by those who aspire to(追求)leadership in the first place. 对产生这种现象的原因一部分是由那些渴望缺乏诚实的自我评估(追求)放在首位的领导 We've all met the type of individual who simply must take charge. Whether it's a decision-making session, a basketball game, or a family outing, they can't help grabbing the lead dog position and clinging on to it for dear life. They believe they're natural born leaders. 我们都遇到了个人的类型,他们必须负责。无论是决策会议,篮球比赛,还是家庭外出,他们都不能不抓住领导的狗的地位,并紧紧抓住它,因为亲爱的生命。他们相信他们是天生的领袖。 Truth is, they're nothing of the sort. True leaders don't assume that it's their divine(神圣的)right to take charge every time two or more people get together. Quite the opposite. A great leader will assess each situation on its merits, and will only take charge when their position, the situation, and/or the needs of the moment demand it. 事实是,他们没有什么样的。真正的领导者不认为这是他们的神圣(神圣的)负责每次两个或两个以上的人在一起吧。恰恰相反。一个伟大的领导者会对每一个情况进行评估,并在他们的位置、情况和/或需要的情况下,只会负责。 Many business executives confuse leadership with action. They believe that constant motion somehow generates leadership as a byproduct. Faced with any situation that can’t be solved by the sheer force of activity, they generate a dust cloud of impatience. Their one leadership tool is

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?
