Unit 9 Science and Technology

太快了吗?

1 在第一次世界大战前夕出生的人仍然记得看到身边经过的汽车就挥手的情景。那时,见到一辆汽车就像观看游行一样令人兴奋、非同寻常。另一项新发明就是飞机了(当时

被拼作“aeroplane”)。当时的电冰箱只是些“冰盒子”(icebox),而且有人夏天专门为

冰盒子送冰,冬天为火炉送炭。现在,送冰的人就像铁匠一样只有在文学作品中才能读

到了。

2 如今,变化来得如此之快,以至于从业人员往往人到中年却因所从事的职业不复存

在而变得一无用处。知识以及随之而来的变化速度都成几何级数增长。每一个想法能引

发出许多新的想法,而每一个新想法又引发更多的想法。第一次世界大战前出生的这代

人还没有来得及掌握那个时代的诸多发明时又面临一批更高级的发明的挑战。原子时代

起始于1945年,确切地说是那一年的8月6日;我们尚未有喘息的机会,太空时代便来

临了。

3 以前, 变化并不总是这样快的。一些重要的发明,如电话、飞机、汽车和收音机,早

在1914年以前就已经问世,但直到许多年后普通老百姓才感受到这些发明对他们生活所

产生的影响。现在我们的技术足以开发人们一时还接受不了的新机器。例如,我们的技

术可以让人通过电话付款,但即便有电话的人也抵制这项技术。这一变化来得太快了。

人们不愿对着机器说话,尤其是当回话的也是机器的时候。

4 有一点是肯定的,那就是技术,特别是计算机技术,将在越来越大的程度上控制我们的生活。这种情况并非一定是有利的或者是不利的。如果变化来得慢一点,许多人可能会觉得更适应一些;但另一方面,对不少人来说,每一项新发明都像是一个新玩具。他们迫不及待地期待着下一个新发明的出现。在科学家们谈论人的非凡的适应性时,他们想到的可能就是这群人。

5 但是每个人的适应能力都是有限的。一旦变化来得过快以至于我们不能再适应时,

我们会怎样呢?还是那些认为我们有非凡适应性的科学家们告诉我们,变化在一定程度

上给每个人造成情感上的痛苦。那么,一旦变化迅速得使我们忍受不了这种痛苦从而拒

绝变化的时候,我们又会怎样呢?

6 关于科技变化,我们读到过很多, 但这只是现代生活的一部分。科学发现和文化上认

可之间常常存在着一个很长的滞后阶段。例如,查尔斯·达尔文在一百多年以前就提出

了进化论,而且为好几代的严肃学者所接受,但至今许多大的社会群体仍然拒绝接受这

一理论。这些人认为科学是与更高的宗教权威相抵触的。在他们看来,科学在质疑甚至

破坏他们的信仰与文化。

7 这一问题很难得到解决,因为科学的本质是质疑,而人类的天性则不容怀疑他们所

相信的东西。科学不仅仅是门学科,就像化学、物理或生物那样。科学还是一种看待世

界的方法,这种方法要求人们思想开明,持客观的态度和根据观察和实验来获得证据。

这是一种脱离了宗教、种族、民族、经济、道德和伦理的方法。它只注重研究的结果。

这种科学方法已经给我们展示了无穷的奇迹和成就, 但它无法提供所有问题的答案。科学

不能告诉我们是否应该投放炸弹:这是一个道德或政治问题。科学只能告诉我们如何制

造炸弹。

8 正如我们前面所说的,技术革新的速度越来越快。未来社会的变革将超过以往任何

时候。作为一个物种,我们人类能否在我们自己发动的这种变革中幸存下来呢?有大量

的证据表明我们能。我们人类有巨大的潜能,我们才刚刚开始开发利用。例如,我们才

刚刚开始控制环境。将来有一天,技术将使所有的沙漠鲜花盛开。这的确不难。要做到这一点,我们只需要降低海水淡化的成本。接下来的问题是,沙漠变成绿洲后,它们能为我们不断增加的人口提供充足的粮食吗?很可能。最近,我们已经开始发现集约式沙漠农业是可能的。我们已经拥有的技术能将产量提高10倍,用水量减少到从前的1/20。

9 我们知道如何创造农业奇迹。我们需要时间和金钱以便使这项技术为人人所用。

10 在19世纪,人们信仰进步。他们相信科学将带领他们进入一个无限繁荣无限幸福的新时代。然而,事情并没有像他们所想象的那样发展。两次灾难性的世界大战使人们确信了这一点。但是,我们在失望时,在担心科学是一头将来某一天会毁灭我们的巨兽时,却忘记了科学并不是巨兽,我们自己才是巨兽。科学只是一个仆人,像火一样,如果使用得当,它将是个好仆人。

11 尽管现代世界存在着种种问题,大多数人都不会愿意生活在我们之前的任何一个科学欠发达的时代。如果我们不在战争中毁灭自己——这确实是不可能发生的——未来只会更好。我们每年都将取得令人目不暇接的科学进步:疾病得到根治,太空被征服,运输和通讯取得根本性的变革,农业和工业得到彻底改造等等。对一些人来说,未来听起来令人兴奋;而对另一些人来说,则令人恐惧。但有一点是肯定的:未来不会让人感到乏味。

Part 1 Listening 1 Ex1: C A D C B Ex2: 1) approaching 2) left 3) toilet 4) locked 5) Tickets please 6) pushed 7) stamped Scripts: Two Belgians and two Dutchmen traveled regularly to work on the same train. After a while the Dutchmen saw that the two Belgians only had one ticket between them and asked how they managed to achieve this. The Belgians explained that when they heard the conductor approaching from the other end of the carriage, the two of them left their seats, went into the toilet and locked the door. When the conductor knocked on the toilet door, saying, "Tickets, please!", they pushed one ticket under the door. It was then stamped and pushed back under the door again. The Dutchmen thought this was a very good idea and the following morning bought one ticket between them. When they got to their carriage there was only one Belgian. They told him what they had done and asked the Belgian if he had a ticket as he was traveling on his own. The Belgian said he did not have a ticket at all and when they asked how he proposed to manage to travel free of charge, he told them they would have to wait and see until the conductor arrived, but he had no doubt that he would manage it without difficulty. As soon as they heard the conductor coming, the two Dutchmen immediately went to the toilet and locked the door. A few moments later, the Belgian followed them down the corridor and knocked on the toilet door, saying, "Tickets, please!" One ticket appeared under the door. Questions: 1. Where did the story take place 2. What did the two Dutchmen want to know from the two Belgians 3. How did the Dutchmen feel about the Belgians' behavior 4. What did the Belgian do when asked if he had a ticket 5. Who finally managed to travel free of charge Listening 2 Ex1: 1 department store 2. attend college 3. difficult 4. physical education 5. terrified Ex2: FTTFT Scripts: My name is Atsuko Saeki. I work as a salesclerk in a big department store in Fuji, Japan. Six years ago when I was 21 years old, I went to California to attend college. Life in the United States was much more difficult than I had ever imagined. It wasn't like the descriptions I had read in my textbooks. People often seemed tense and so I felt very alone. One of my hardest classes was physical education. We often played volleyball. All the other students were good at it, but I clearly wasn't. One afternoon, the teacher asked me to hit the ball to my classmates. For most people, this would be easy but I was terrified that I would make a fool of myself. When one of the boys on my team saw how nervous I was, he walked up to me and whispered, "Come on, you can do that." You can't imagine how those words of encouragement made me feel. I was so happy that I almost cried. I managed to hit the ball and I think I thanked the young man, but I'm not sure. I have never forgotten his kind words of encouragement. He probably doesn't even remember what he said to me or how much his kindness meant to me. Whenever things aren't going well, I think of those simple words of encouragement: Come on, you can do that.

课内阅读参考译文及课后习题答案(Book 4) Unit 1 享受幽默—什么东西令人开怀? 1 听了一个有趣的故事会发笑、很开心,古今中外都一样。这一现象或许同语言本身一样悠久。那么,到底是什么东西会使一个故事或笑话让人感到滑稽可笑的呢? 2 我是第一次辨识出幽默便喜欢上它的人,因此我曾试图跟学生议论和探讨幽默。这些学生文化差异很大,有来自拉丁美洲的,也有来自中国的。我还认真地思考过一些滑稽有趣的故事。这么做完全是出于自己的喜好。 3 为什么听我讲完一个笑话后,班上有些学生会笑得前仰后合,而其他学生看上去就像刚听我读了天气预报一样呢?显然,有些人对幽默比别人更敏感。而且,我们也发现有的人很善于讲笑话,而有的人要想说一点有趣的事却要费好大的劲。我们都听人说过这样的话:“我喜欢笑话,但我讲不好,也总是记不住。”有些人比别人更有幽默感,就像有些人更具有音乐、数学之类的才能一样。一个真正风趣的人在任何场合都有笑话可讲,而且讲了一个笑话,就会从他记忆里引出一连串的笑话。一个缺乏幽默感的人不可能成为一群人中最受欢迎的人。一个真正有幽默感的人不仅受人喜爱,而且在任何聚会上也往往是人们注意的焦点。这么说是有道理的。 4 甚至有些动物也具有幽默感。我岳母从前经常来我们家,并能住上很长一段时间。通常她不喜欢狗,但却很喜欢布利茨恩—我们养过的一条拉布拉多母猎犬。而且,她们的这种喜欢是相互的。布利茨恩在很小的时候就常常戏弄外祖母,当外祖母坐在起居室里她最喜欢的那张舒适的椅子上时,布利茨恩就故意把她卧室里的一只拖鞋叼到起居室,并在外祖母刚好够不到的地方蹦来跳去,一直逗到外祖母忍不住站起来去拿那只拖鞋。外祖母从椅子上一起来,布利茨恩就迅速跳上那椅子,从它那闪亮的棕色眼睛里掠过一丝拉布拉多式的微笑,无疑是在说:“啊哈,你又上了我的当。” 5 典型的笑话或幽默故事由明显的三部分构成。第一部分是铺垫(即背景),接下来是主干部分(即故事情节),随后便是妙语(即一个出人意料或令人惊讶的结尾)。如果这个妙语含有一定的幽默成分,这个笑话便会很有趣。通常笑话都包含这三部分,而且每部分都必须交代清楚。如果讲故事或说笑话的人使用听众都熟悉的手势和语言,则有助于增强效果。 6 我们可以对幽默这种娱乐形式,进行分析,从而发现究竟是什么使一个有趣的故事或笑话令人发笑。举例来说,最常见的幽默有以下几种,包括了从最显而易见的幽默到比较微妙含蓄的幽默。 7 “滑稽剧”是最明显的幽默。它语言简单、直截了当,常常以取笑他人为乐。说笑打闹这种形式过去是、现在仍然是滑稽说笑演员和小丑的惯用技巧。它为不同年龄、不同文化背景的人们所喜爱。几乎本世纪的每个讲英语的滑稽说笑演员都曾以这样或那样的方式说过下面这则笑话。一位男士问另一位男士:“昨晚我看到的那位和你在一起的贵妇是谁?”那位男士回答道:“那可不是什么贵妇,那是我老婆。”这个笑话的幽默之处在于第二位男士说他的妻子不是一位贵妇,也就是说她不是一个高雅的女人。这个笑话并没有因为经常讲而变得不再那么好笑。由于这是一个经典笑话,观众都知道要说什么,而且因为大家对这个笑话很熟悉而更加珍爱它。 8 中国的相声是一种特殊的滑稽剧。相声中两名中国喜剧演员幽默地谈论诸如官僚主义者、家庭问题或其他一些有关个人的话题。相声随处都能听到,无论是在乡村的小舞台上,还是在北京最大的剧院里,抑或在广播、电视上。它显然是中国人家喻户晓的一种传统的幽默形式。 9 “俏皮话”不像滑稽剧那样浅显,它是因语言的误用或误解而引人发笑。我特别喜欢

最新Unit 6 Risks新编大学英语第二版第四册课文翻译资料

Unit 6 Risks Risks and You At some time or other, all of us have played the part of a hypochondriac, imagining that we have some terrible disease on the strength of very minor symptoms. Some people just have to hear about a new disease and they begin checking themselves to see if they may be suffering from it. But fear of disease is not our only fear, and neither is risk of disease the only risk we run. Modern life is full of all manner of threats-to our lives, our peace of mind, our families, and our future. And from these threats come questions that we must pose to ourselves: Is the food I buy safe? Are toys for my children likely to hurt them? Should my family avoid smoked meats? Am I likely to be robbed on vacations? Our uncertainties multiply indefinitely. Anxiety about the risks of life is a bit like hypochondria; in both, the fear or anxiety feeds on partial information. But one sharp difference exists between the two. The hypochondriac can usually turn to a physician to get a definitive clarification of the situation-either you have the suspected disease or you don't. It is much more difficult when anxiety about other forms of risk is concerned, because with many risks, the situation is not as simple. Risks are almost always a matter of probability rather than certainty. You may ask, "Should I wear a seat belt?" If you' re going to have a head-on collision, of course. But what if you get hit from the side and end up trapped inside the vehicle, unable to escape because of a damaged seat belt mechanism? So does this mean that you should spend the extra money for an air bag? Again, in head-on collisions, it may well save your life. But what if the bag accidentally inflates while you are driving down the highway, thus causing an accident that would never have occurred otherwise? All of this is another way of saying that nothing we do is completely safe. There are risks, often potentially serious ones, associated with every hobby we have, every job we take, every food we eat-in other words, with every action. But the fact that there are risks associated with everything we are going to do does not, or should not, reduce us to trembling neurotics. Some actions are riskier than others. The point is to inform ourselves about the relevant risks and then act accordingly. For example, larger cars are generally safer than small ones in collisions. But how much safer? The answer is that you are roughly twice as likely to die in a serious crash in a
