Many countries have, or are in the process of creating, their own "Silicon Valley". So far, none has as yet threatened the preeminence of the US prototype. What makes Silicon Valley such a unique entity? There are several crucial factors.First and foremost, it has the largest concentration of brilliant computer professionals and the best supporting services in the world, and easy access to world-class research institutions, like Stanford University, which continually nurtures would-be geniuses which the industry needs in order to move forward. Without these advantages, the Valley would be a different place.Secondly, it actively encourages, or even exalts, risk-taking. Hence, failure holds no terror and there is no stigma attached to a failed effort. On the contrary, they will try even harder next time round. Such never-say-die approach is the sine qua non for the ultimate triumph in entrepreneurship and technological breakthrough.A third decisive factor is the vital role of venture capitalists who willingly support promising start-ups with urgently needed initial capital to get them started. Some would even give failed entrepreneurs a second chance if convinced that a fresh concept might lead to eventual success.

Their population has been dwindled from 1.3 million in 1979 to just 625,000 today, and the rate of killing has been accelerating in recent years because many of the older, bigger tusked animals have already been destroyed. "The poachers now must kill times as many elephants to get the same quantity of ivory," explained Curtis Bohlen,Senior vice president of the World Wildlife Fund. Though its record on the environment has been spotty so far, the government last week took the lead in a major conservation issue by imposing a ban on ivory imports into the US. The move came just four days after a consortium of conservation groups, including the World Wildlife Fund and Wildlife Conservation International, called for that kind of action, and it made the US the first nation to forbid imports of both raw and finished ivory. The ban, says Bohlen, sends a very clear message to the ivory poachers that the game is over. In the past African nations have resisted an ivory ban, but increasingly they realized that the decimation of the elephant herds poses a serious threat to their tourist business. Last month Tanzania and several other African countries called for an amendment to the 102 nation Convention on International Trade in Endangered Species that would make the ivory trade illegal worldwide. The amendment is expected to be approved at an October meeting in Geneva and to go into effect next January.

    第一篇

    Human Evolution

    Being a man has always been dangerous.There are about 105 males born for every 100 females, but this ratio drops to near balance at the age of maturity,and among 70-year-old there are twice as many women as men. But the great universal of male mortality is being changed.Now,boy babies survive almost as well as girls do. This means that,for the first time,there will be an excess of boys in those crucial years when they are searching for a mate. More important,another chance for natural selection has been removed. Fifty years ago,the chance of a baby(particularly a boy baby)surviving depended on its weight. A kilogram too light or too heavy meant almost certain death.Today it makes almost no difference.Since much of the variation is due to genes,one more agent of evolution has gone.
    There is another way to commit evolutionary suicide:stay alive,but have fewer children.Few people are as fertile as in the past. Except in some religious communities,very few women have 15 children.Nowadays the number of births,like the age of death,has become average.Most of us have roughly the same number of offspring. Again,differences between people and the opportunity for natural selection to take advantage of it have diminished.India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples.The grand mediocrity of today一everyone being the same in survival and number of offspring means that natural selection has lost 80%of its power in upper-middle一class India compared to the tribes.
    For us,this means that evolution is over;the biological Utopia has arrived.Strangely,it has involved little physical change.No other species fills so many places in nature.But in the past 100,000 years一even the past 100 years一our lives have been transformed but our bodies have not. We did not evolve,because machines and society did it for us.Darwin had a phrase to describe those ignorant of evolution:"they look at an organic being as savage looks at a ship,as at something wholly beyond his comprehension."No doubt we will remember a 20th century way of life beyond comprehension for its ugliness. But however amazed our descendants may be at how far from Utopia we were,they will look just like us.

    What does the last sentence mean?
    A:It means that we are still very far from Utopia.
    B:It means that our descendants look like us because of little biological change.
    C:It means that our descendants will not reach Utopia either.
    D:None of the above.

    答案:B
    解析:
    文中第一段提到“做男人从来都充满危险,新生儿男女比例大约是105: 100,但到了成年,这一比例基本持平,而在70岁的老年人中,女性是男性的两倍。但是男性死亡率高这种普遍情况正在改变,现在男婴存活率同女婴的基本一样高”,这说明男人的存活率相对是比较低的。
    使用事例来证明是常见的逻辑思维模式。既然有事例,我们就需要看到它的论点是什么。本文中提到,“还有一种方法确保进化意义上的自杀:存活,但少生孩子”。首先,“现在几乎没有人像过去那样多育。除了在一些宗教社区,基本没有妇女会生巧个孩子”表明了“当今出生的数量同死亡年龄一样变得平均化,我们大多数人的子女数量大致相当”。其次,人与人之间的差异和利用差异进行自然选择的机会再次减少了。再次,“印度证明了这种情况。这个国家给大城市里的少数人提供财富,而给其余的各部落居民造成了贫困。今天这种每个人的生存机会和子女数量都相同的极其显著的平均化意味着与部落相比,自然选择在印度社会中上层人群中,已经失去了80%的效力”是为了证明“人与人之间的差异和利用差异进行自然选择的机会再次减少了”,换言之,“自然选择在穷人和富人之间几乎不起作用”。答案应该是B选项。
    文中提到停止进化是在第三段第一句“对我们来说,这意味着进化已经结束”。第三段中指出,“在过去的10万年―甚至过去的100年中,我们的生活发生了变化,我们的身体却没变。我们没有进化。因为机器和社会替我们办了这一切”。“机器”代表的就是 “技术”,因此我们可以判定A是正确答案。
    文章中在第一段结尾提到“由于大部分差异是由基因引起的,又一个进化的因素消失了”。第二段中说“再一次,人与人之间的差异和利用差异进行自然选择的机会减少了”。第三段提到“但我们的身体却没变。我们没有进化,因为机器和社会替我们办了这一切”。这些都表明作者认为进化机制已不再起作用,认为自然进化机制已不能再左右人口的出生率。在总结全文的第三段时,作者直截了当地指出,进化已经结束。因此可以认为人类的进化是无路可走的。另外三个选项都不全面或者不对题。
    文章的最后一句话是说“不管我们的子孙后代对我们离乌托邦的理想境界还差多远感到多么惊讶,他们的样子会同我们差不了多少”。这一句是和本段开始相呼应,都是谈论进化已经结束,生物学上的乌托邦已形成,并且这一过程几乎丝毫没有造成人的身体上的改变,因此是在谈论人的外貌。只有选项B正确。

    Better Solar Energy Systems: More Heat, More Light
    Solar photovoltaic thermal energy systems,or PVTs,generate both heat and electricity,but until now they haven't been very good at the heat-generating part compared to a stand-alone solar thermal collector. That's because they operate at low temperatures to cool crystalline silicon solar cells,which lets the silicon generate more electricity but isn't a very efficient way to gather heat.
    That's a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it's also a space problem:photovol-taic cells can take up all the space on the roof,leaving little room for thermal applications.
    In a pair of studies,Joshua Pearce,an associate professor of materials science and engineer-ing,has devised a solution in the form of a better PVT made with a different kind of silicon.His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen's University,Canada.
    Most solar panels are made with crystalline silicon,but you can also make solar cells out of amorphous silicon,commonly known as thin-film silicon.They don't create as much electricity, but they are lighter,flexible,and cheaper. And,because they require much less silicon,they have a greener footprint. Unfortunately,thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.
    "That means that their efficiency drops when you expose them to light-pretty much the worst possible effect for a solar cell,"Pearce explains,which is one of the reasons thin-film solar panels make up only a small fraction of the market.
    However,Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new type of PVT. You don't have to cool down thin-film silicon to make it work.In fact,Pearce's group discovered that by heating it to solar-thermal operating temperatures,near the boiling point of water,they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-fulm silicon directly to a solar thermal en-ergy collector,they also found that by baking the cell once a day,they boosted the solar cell's e-lectrical efficiency by over 10 percent.

    PVTs are not efficient in______.
    A:.creating electricity
    B: cooling silicon solar cells
    C: generating heat
    D: powering solar thermal collectors

    答案:C
    解析:
    根据第一段“they haven't been very good at the heat-generating part...”可知,与太阳热能单机收集器相比,传统太阳能光伏热能系统在转换热能方面效率不是很高。


    根据第二段可知,光电管占去屋顶的所有空间,几乎没有空间留给热能的产出。因此,传统太阳能光伏热能系统存在的一个问题是,占用太多空间,即C选项。文章也提到好的太阳能热水系统比太阳能电力系统成本低得多,但并没有说传统太阳能光伏热能系统贵到人们买不起的程度,因此B项错误。故本题选C。


    根据第四段“...but they are lighter , flexible , and cheaper. And , because they requiremuch less silicon , they have a greener footprint.”可知,选项B,C,D在文中都直接提到,A 项没有提到。


    根据第五段可知,薄型太阳能板只占有市场的一少部分的原因是,当被暴露在光线下,那就意味着它们的能效会降低——这几乎是太阳能电池最可能糟糕的效应。


    通读文章最后一段可知,如果一天把太阳能电池加热一次,那么太阳能的电力效能会增加10%。即A选项正确,其他三项在文中并未提及。

    Compared with other areas of our social lives,we tend to boast far more on social media.For instance,few of us will stand on a neighborhood corner and declare how accomplished we are or how much we love our spouse.On Facebook,however,we have no uneasiness about routinely posting photographs of intimate family gatherings,foreign vacations,and fancy meals.What's more,many of us share boasts with hundreds or even thousands of social media connections,with little knowledge or concern about who's seeing them or what effect it has on them.Despite the risk of negative effects,we can't help boasting on social media because,as psychologists have argued,boasting satisfies fundamental human motives of creating a favorable first impression with strangers,and building a positive image among those who know us.In our vast social media spheres,boasting is also a good way,or even possibly the only way,to attract attention.


    答案:
    解析:
    和我们社交生活的其他领域相比.我们在社交媒体上自夸的频率往往要高得多。比方说,我们很少人会站在街角,宣称自己如何有成就、多么爱自己的配偶。但是,我们例行公事般地在脸书上发布亲密家庭成员聚会、出国度假及豪华大餐的照片而丝毫不觉不安。不仅如此,我们很多人与数以百计甚至千计的社交媒体联系人分享自己引以为豪的事物,对谁在看它们、它们产生了什么影响既不怎么了解,也不怎么关心。尽管存在带来负面效果的风险,我们还是禁不住在社交媒体上自吹自擂,因为正如心理学家所言,自夸满足了人类的基本动机:给陌生人留下美好的第一印象,在熟人中树立正面形象。在我们庞大的社交媒体圈子中,自夸也是引起关注的一个好方法,甚至可能是唯一的方法。

    Passage 1  Britain is still home to some of the world’s best scientists—but when it comes to giving them the money to turn their ideas into world-beating companies we are third-rate. True?  “That’s gulf,” is the impatient response of Anne Glover, a leading venture capitalist.  She believes this is the best time since the short-lived dot corn bubble for anyone looking to get their idea funded: “It’s never been better, except during the boom for a short nine-month period.”  Not from the perspective of Noah Freedman, who has tried to get venture capital firms interested in Ionscope, a firm using world-leading science from Imperial College and Cambridge University. “I don’t think the situation has improved in the UK over the last decade,” he says.  But Anne Glover, whose venture capital firm Amadeus Capital has backed businesses such as lastminute, corn, Cambridge Silicon Radio and Plastic Logic, points to the figures.  Last year £lbn of venture capital money was invested in young firms in the UK—that’s more than a third of all the money invested across Europe.  “We get beaten up all the time,” says Ms Glover, “but which other sector has as big a share of the European market?”  And just as in other industries there are fashions in venture capital. What’s hot right now? Mobile technology, semi-conductors, and consumer internet firms, according to Amadeus—rather similar to what was getting funded during the last booming 2000.  That ended with a bust which sawn many start-ups disappear and “was followed by several years in which venture capitalists seemed to have gone into hiding. But Anne Glover says they’ve come through the experience stronger.  “The ones who have survived the boom and bust are experienced and well-funded and have similar global aspirations to the best entrepreneurs.”  But Noah Freedman, an entrepreneur who was previously involved in Brainspark, an incubator for technology start-ups, says there is still a funding gap.  Ionscope, which makes very high resolution microscopes, was not able to raise venture capital until it had sold its first products. “The bottom line is that in the UK, it may be easy to get venture capital money to fund growth of an established concept or business, but it is exceptionally difficult to get seed and start-up money for real innovation.”  Anne Glover says the real problem is a lack of ambition, from both investors and entrepreneurs.  “We maybe spread our money too thinly rather than concentrate on the best ideas. When we’ve got a world-leading company that’s the point where we need to finance it properly.”  She says she spends more time trying to raise the ambitions of start-up firms rather than lower them.  So what’s the lesson from those who have made it? Alex van Someren is one entrepreneur who did raise the money to create a successful global business.  His Cambridge-based internet security company Ncipher raised venture capital money between 1996 and 2000, and then floated just in the nick of time before the stock market crash.  He believes we are making progress: “Both investors and the people they invest in have become much more sophisticated.” He says the problem is not a lack of money or ideas. “There is plenty of both—but ideas are not the same as investable businesses.”  But he says young companies are now more likely to turn to business angels—often people who have built their own firms—rather than venture capitalists: “Angels have done it themselves, so they bring more added value—and they’re willing to invest in businesses too small for venture funds to look at.”  What Britain doesn’t have—despite attempts to brand Cambridge as Silicon Fen—is one area that can compete with Silicon Valley as a place which produces innovative businesses and the investors to fund them.  But Anne Glover says we shouldn’t get hung up on the comparison: “You would find the same inferiority complex in Indiana or Wisconsin—Silicon Valley is unique. It’s difficult to raise venture capital anywhere in the world. Entrepreneurship is hard and don’t expect it to be easy.”  The good news is that, when it comes to innovation, Britain has a growing number of entrepreneurs who have been there and done that.  Many are now starting new firms or investing in other start-ups. Their only fear is that the latest boom in technology investment could melt away like the last one.  1. Briefly describe the last boom.  2. What advantages have the companies which survived last boom got?  3. What is the difference on capital choice for young companies between the last boom and this latest one? Why?

    正确答案: 【参考答案】
    1. It happened in 2000 and lasted nine month. / It focused on Mobile technology, semi-conductors, and consumer internet firms. / It ended with many start-ups disappear and venture capitalists seemed to have gone into hiding.
    2. They are experienced and well-funded and have similar global aspirations to the best entrepreneurs.
    3. They are more likely to turn to business angels rather than venture capitalists because angels have done it themselves, so they bring more added value./Business angels are willing to invest in businesses too small for venture funds to look at.

    China has the greatest population in the world and a large pool of research workers, yet it has not produced a single Nobel Prize winner so far. What has caused this situation in your opinion? State your opinion in about 160 words, and write it on the answer sheet.

    正确答案:
    We can often hear the news that an American scientist or a Poland researcher get the Nobel Prize for certain inventions or findings, but China, with the greatest population in the world and a large number of research workers, yet has not produced a single Nobel Prize winner so far. There are various reasons for that.
    First, there are serious problems in the educational system in China. The Chinese education has long been examination-oriented, which means that students are just forced to swallow the existing knowledge, without thinking much about it. Thus, the researchers think that the systems fostered are lacking in a sense of creativity.
    Second, there is too little academic communication between China and the outside world. Due to some historical reasons, China had been isolated from the outside world. Thus it lags behind other countries in science and technology. So what scientists in China are doing now is mainly a repeat of their western counterparts.
    Realizing the problems, the government has made many adjustments: the quality-oriented education is gradually taking the place of the examination-oriented one and a great number of leading technology and experts from the foreign countries are brought in. So, it’s certain that in the near future there will be Nobel Prizewinners in China.

    Robert F.Kennedy once said that a country’s GDP measures“everything except that which makes life worthwhile.”With Britain voting to leave the European Union,and GDP already predicted to slow as a result,it is now a timely moment to assess what he was referring to.The question of GDP and its usefulness has annoyed policymakers for over half a century.Many argue that it is a flawed concept.It measures things that do not matter and miss things that do.By most recent measures,the UK’s GDP has been the envy of the Western World,with record low unemployment and high growth figures.If everything was going so so well,then why did over 17million people vote for Brexit,despite the warnings about what it could do to their country’s economic prospects?A recent annual study of countries and their ability to convert growth into well-being sheds some light on that question.Across the 163 countries measured,the UK is one of the poorest performers in ensuring that economic growth is translated into meaningful improvement for its citizens.Rather than just focusing on GDR over 40 different sets of criteria from health,education and civil society engagement have been measured to get a more rounded assessment of how countries are performing.While all of these countries face their own challenges,there are a number of consistent themes.Yes,there has been a budding economic recovery since the 2008 global crash,but in key indicators in areas such as health and education,major economies have continued to decline.Yet this isn't the case with all countries.Some relatively poor European countries have seen huge improvements across measures including civil society;income equality and the environment.This is a lesson that rich countries can learn:When GDP is no longer regarded as the sole measure of a country’s success,the world looks very different.So what Kennedy was referring to was that while GDP has been the most common method for measuring the economic activity of nations,as a measure,it is no longer enough.It does not include important factors such as environmental equality or education outcomes-all things that contribute to a person's sense of well-being.The sharp hit to growth predicted around the world and in the UK could lead to a decline in the everyday services we depend on for our well-being and for growth.But policymaker who refocus efforts on improving well-being rather than simply worrying about GDP figures could avoid the forecasted doom and may even see progress.
    Which of the following is true about the recent annual study?

    A.It excludes GDP as an indicator.
    B.It is sponsored by 163 countries.
    C.Its criteria are questionable.
    D.Its results are enlightening.

    答案:D
    解析:
    事实细节题。根据题目定位到第三段第一句A recent annual study of countries and their ability to convert growth into well-being sheds some light on the question,该句表明,最近年度研究调查了各国家和他们将经济增长转换为幸福感的能力,这对这个问题有所启发。说明研究的结果有利于解决经济增长与幸福感的关系。shed some light on与D选项enlightening是同义替换,因此答案为D

  • 第14题:

    African elephants have been slaughtered at alarming rate over the past decade, largely because they are the primary source of the world's ivory. Their population has been dwindled from 1.3 million in 1979 to just 625,000 today, and the rate of killing has been accelerating in recent years because many of the older, bigger tusked animals have already been destroyed. "The poachers now must kill times as many elephants to get the same quantity of ivory," explained Curtis Bohlen, Senior vice president of the World Wildlife Fund.
    Though its record on the environment has been spotty so far, the government last week took the lead in a major conservation issue by imposing a ban on ivory imports into the US. The move came just four days after a consortium of conservation groups, including the World Wildlife Fund and Wildlife Conservation International, called for that kind of action, and it made the US the first nation to forbid imports of both raw and finished ivory. The ban, says Bohlen, sends a very clear message to the ivory poachers that the game is over.
    In the past African nations have resisted an ivory ban, but increasingly they realized that the decimation of the elephant herds poses a serious threat to their tourist business. Last month Tanzania and several other African countries called for an amendment to the 102 nation Convention on International Trade in Endangered Species that would make the ivory trade illegal worldwide. The amendment is expected to be approved at an October meeting in Geneva and to go into effect next January. But between now and then, conservationists contend, poachers may go on a rampage, killing elephants wholesale, so nations should unilaterally forbid imports right away. The US government brought that argument, and by week's end the twelve nation European Community had followed with its own ban.
    According to the passage, "dwindle" means______

    A. decrease
    B. enlarge
    C. weaken
    D. eliminate

    答案:A
    解析:
    本题测试对词义的理解。根据原文可知,大象的数量在急剧减少.面表示“减少”之意的,答案A最合适。

    A:encouraged
    B:endangered
    C:endorsed
    D:enlarged

    答案:A
    解析:
    本句意思:在那个荒凉的山谷中发现的奇异石头激发了一系列的科学研究。encourage的 意思为“激励,鼓励”;endanger的意思为“使……处于险境”;endorse的意思为“赞同,签名”;en- larg。的意思为“使增大”。spur的意思为“激励,促进”,和encourage的意思接近。

    Better Solar Energy Systems: More Heat, More Light
    Solar photovoltaic thermal energy systems,or PVTs,generate both heat and electricity,but until now they haven't been very good at the heat-generating part compared to a stand-alone solar thermal collector. That's because they operate at low temperatures to cool crystalline silicon solar cells,which lets the silicon generate more electricity but isn't a very efficient way to gather heat.
    That's a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower cost. And it's also a space problem:photovol-taic cells can take up all the space on the roof,leaving little room for thermal applications.
    In a pair of studies,Joshua Pearce,an associate professor of materials science and engineer-ing,has devised a solution in the form of a better PVT made with a different kind of silicon.His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen's University,Canada.
    Most solar panels are made with crystalline silicon,but you can also make solar cells out of amorphous silicon,commonly known as thin-film silicon.They don't create as much electricity, but they are lighter,flexible,and cheaper. And,because they require much less silicon,they have a greener footprint. Unfortunately,thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.
    "That means that their efficiency drops when you expose them to light-pretty much the worst possible effect for a solar cell,"Pearce explains,which is one of the reasons thin-film solar panels make up only a small fraction of the market.
    However,Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new type of PVT. You don't have to cool down thin-film silicon to make it work.In fact,Pearce's group discovered that by heating it to solar-thermal operating temperatures,near the boiling point of water,they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-fulm silicon directly to a solar thermal en-ergy collector,they also found that by baking the cell once a day,they boosted the solar cell's e-lectrical efficiency by over 10 percent.

    Which of the following statrnents is true?
    A: Thin-film silicon's electrical efficiency improves when heated up.
    B: New techniques have been developed to produce thin-film silicon.
    C: Thin-film silicon works efficiently at low temperature.
    D: A new material enlarging the Staebler-WronsKi effect has been created.

    答案:A
    解析:
    根据第一段“they haven't been very good at the heat-generating part...”可知,与太阳热能单机收集器相比,传统太阳能光伏热能系统在转换热能方面效率不是很高。


    根据第二段可知,光电管占去屋顶的所有空间,几乎没有空间留给热能的产出。因此,传统太阳能光伏热能系统存在的一个问题是,占用太多空间,即C选项。文章也提到好的太阳能热水系统比太阳能电力系统成本低得多,但并没有说传统太阳能光伏热能系统贵到人们买不起的程度,因此B项错误。故本题选C。


    根据第四段“...but they are lighter , flexible , and cheaper. And , because they requiremuch less silicon , they have a greener footprint.”可知,选项B,C,D在文中都直接提到,A 项没有提到。


    根据第五段可知,薄型太阳能板只占有市场的一少部分的原因是,当被暴露在光线下,那就意味着它们的能效会降低——这几乎是太阳能电池最可能糟糕的效应。


    通读文章最后一段可知,如果一天把太阳能电池加热一次,那么太阳能的电力效能会增加10%。即A选项正确,其他三项在文中并未提及。

    What makes Silicon Valley such a unique entity? There are several crucial factors. First and foremost, it has the largest concentration of brilliant computer professionals and the best supporting services in the world, and easy access to world-class research institutions, like Stanford University, which continually nurtures would be geniuses which the industry needs in order to move forward. Without these advantages, the Valley would be a different place. Secondly, it actively encourages, or even exalts, risk-taking. Hence, failure holds no terror and there is no stigma attached to a failed effort. On the contrary, they will try even harder next time round. A third decisive factor is the vital role of venture capitalists who willingly support promising start-ups with urgently needed initial capital to get them started. Some would even give failed entrepreneurs a second chance if convinced that a flesh concept might lead to eventual success. Of equal importance, many bright young people and middle level professionals are keen to work for a new venture at substantially reduced remuneration, as it offers more scope for entrepreneurship and job satisfaction than the established companies.

    Practice 2  Many matters, however, are less easily brought to the test of experience. If, like most of mankind, you have strong convictions on many such matters, there are ways in which you can make yourself aware of your own prejudices. If an opinion contrary to your own makes you angry, that is a sign that you subconsciously are aware of having no good reason for thinking as you do. If someone maintains that two and two are five, or that Iceland is on the equator you feel pity rather than anger, unless you know so little of arithmetic or geography that his opinion shakes your own contrary conviction. The most savage controversies are those about matters as to which there is no good evidence either way. So whenever you find yourself getting angry about difference of opinion, be on your guard; you will probably find, on examination that your belief is going beyond what the evidence justifies.  For those who have enough psychological imagination, it is a good plan to imagine an argument with a person having a different opinion. This has one advantage, and only one, as compared with actual conversation with opponents: this one advantage is that the method is not subject to the same limitations of time and space. Mahatma Gandhi considered it unfortunate to have railways and steamboats and machinery; he would have liked to undo the whole of the industrial revolution. You may never have an opportunity of actually meeting anyone who holds his opinion, because in Western countries most people take the advantage of modern technology for granted. But if you want to make sure that you are right in agreeing with the prevailing opinion, you will find it a good plan to test the arguments that occur to you by considering what Gandhi might have said in refutation of them. I have sometimes been led actually to change my mind as a result of this kind of imaginary dialogue. Furthermore, I have frequently found myself growing more agreeable through realizing the possible reasonableness of a hypothetical opponent.

    然而,很多问题用经验来检验会比较困难。即使你像大多数人那样,在此类事情上执迷不悟,还是有方法让你意识到自己的偏见。如果与你相左的观点激怒了你,这恰恰说明了你已经下意识地认识到自己还没法给自己的想法以合适的理由。如果有人坚称二加二等于五,或者冰岛位于赤道,你更多的是感到同情而非愤怒,除非你对算术或地理几无所知,以致他的观点动摇了你的立场。最残酷的争论是,双方都无法给自己的观点提出合理的证据。所以无论发现自己对不同的意见有多么气恼,一定要保持警惕;你很有可能会发现,经过检验,你的信念并无足够的依据。
    对那些想象力丰富的人,想象着同与自己观点相异的人交锋是项不错的计划。与实际的正面交锋相比,这种方式有一个——可以说是惟一的——好处:它无需受时间与空间的限制。圣人甘地认为拥有铁路、轮船和机器是不幸的,他宁愿整个工业革命未曾发生过。你可能永远也不会遇到一个跟他持有相同观点的人,因为在西方国家,绝大部分人都认为现代科技具有诸多好处。但如果你想证实你赞同时下盛行的观点,这一行为是正确的,你可以通过考虑甘地可能给出的拒绝高科技的理由来检验你所坚持的论断,这将是个十分好的方案。我有时确实通过这种想象式的对话改变了原来的观点。此外,通过认识到假想论敌的观点可能存有的合理性,我经常发现自己已变得越来越容易相处。
