《经济学家》读译参考（第13篇）：一路繁衍——你知道外来入侵物种吗？

Go forth and multiply

一往无前，生生不息

WHAT makes for a successful invasion? Often, the answer is to have better weapons than the enemy. And, as it is with people, so it is with plants—at least, that is the conclusion of a p_______①published in ★Biology Letters[1] by Naomi Cappuccino, of Carleton University, and Thor Arnason, of the University of Ottawa, both in Canada.

怎样才能成功入侵？答案常常是：拥有比敌人更好的武器。人是这样，植物也是如此——至少，《生物书简》上发表的一篇论文是这么认为的，作者是来自加拿大加里敦大学的纳奥米?卡普奇诺和渥太华大学的索尔?阿纳森。

The phenomenon of alien species ★popping up[2] in unexpected parts of the world has grown over the past few d________② as people and goods become more mobile and （1）?plant seeds and animal larvae have ★hitched[3] along for the ride?. Most such aliens blend into the ecosystem in which they arrive without too much fuss. (Indeed, many probably fail to establish themselves at all—but those failures, of course, are never noticed.) Occasionally, though, something ★goes bananas[4] and starts trying to take the place over, and an invasive species is born. Dr Cappuccino and Dr Arnason asked themselves w_______③.

过去的几十年，随着人和货物的流动日益频繁，植物种子和动物幼体也乘机“搭便车”四处播散，世界各地无意间出现了越来越多的外来物种。这些外来物种大多数都轻而易举地融入了所到之处的生态系统。（事实上，许多物种可能还没有站稳脚跟——当然，人们从未注意到这一点。）不过，偶尔也有某些物种疯狂繁殖，开始企图占领原有物种的生长空间，一种入侵物种就这样形成了。卡普奇诺和阿纳森对此感到百思不得其解。

One hypothesis is that aliens leave their predators b________④. Since the predators in their new homelands are not adapted to exploit them, they are able to reproduce unchecked. That is a nice idea, but it does not explain why only certain aliens become invasive. Dr Cappuccino and Dr Arnason suspected this might be because native predators are [b]（2）

?sometimes “pre-adapted” to the aliens' defences?, but in other cases they are not.

有人推想，外来物种摆脱了原先的掠食者，而在新的“家园”，现有的掠食者又没有发现它们也合口味，因此这些物种得以肆无忌惮地繁衍。这种观点好是好，不过没有解释为什么只有特定的外来物种才具有入侵性。卡普奇诺和阿纳森猜测，这可能是因为土生土长的掠食者对外来物种所具有的防御机制有时产生“预适应”，有时又不产生。

To test this, they had first to establish a reliable list of invaders. That is not as easy as it sounds. As they obs erve, “although there are many lists of invasive species published by governmental agencies, inclusion of a given species in the lists （3）?may not be entirely free of political motivation?”. Instead, they polled established researchers in the field of alien species, asking each to list ten invasive species and, for c_________⑤, ten aliens that just ★rubbed along quietly with[5] their neighbours. The result was a list of 21 species widely agreed to be invasive and, for comparison, 18 non-invasive aliens.

为了证实这一猜测，他们必须首先列出一些已经确认的入侵物种。这可不是件轻松的事。正如他们所说，“虽然政府部门公布了许多入侵物种名单，但是把指定物种归入此名单也许多少有些出于政治上的考虑。”为此，他们调查了外来物种领域一些有名望的研究人员，请每人举出10种入侵物种，以及10种与本地物种能和睦共生的外来物种用于对照。最后得到的名单中包括21种被广泛认可的入侵物种和18种用于对照的非入侵性外来物种。

H________⑥established these lists, they went to the library to find out what was known about the plants' chemistry. Their aim was to find the most prominent chemical weapon in each plant, whether that weapon was directed against insects that might want to eat the plant, bacteria and fungi that might want to i_______⑦it, or other plants that might compete for space, water, nutrients and light. Botanists know a lot about which sorts of compounds have what roles, so classifying constituent chemicals in this way was not too hard.

名单确定之后，他们就到图书馆查询这些植物的化学性质，旨在找出每种植物所拥有的作用最为突出的“化学武器”。这种“化学武器”的攻击对象包括可能吃掉该植物的昆虫，使其感染的细菌和真菌以及与其竞争生长空间、水、养料和阳光的其它植物。植物学家对哪些化合物有哪些作用都了如指掌，因此这样对化学物质进行分类并不太难。

The researchers then compared the chemical arsenals of their aliens with those of native North American plants, （4）?to see if superior (or, at least, unusual) weaponry was the explanation for the invaders' success.? Their hypothesis was that highly invasive species would have chemical weapons not found in native plants, and w________⑧ pests, parasites and other plants would therefore not have evolved any resistance to. The more benign aliens, by contrast, were predicted to have arsenals also found in at least some native species.

然后，为了弄清外来物种的成功入侵是否得益于“超级武器“（或者至少是超常武器），这两位研究人员将已知外来物种的“化学武器库”同北美土生土长的植物“化学武器库”进行了比较。他们推断，具有高度入侵性的物种拥有土产植物所缺少的“化学武器”，对这种化学武器，害虫、寄生虫及其它植物都不能产生任何抵抗力。相比之下，入侵性较弱的外来物种所具有的“武器库”可能至少同样存在于某些土产物种。

And so it proved. More than 40% of the invasive species had a chemical unknown to native plants; just over 10% of the non-invasive aliens had such a chemical. M_________⑨, when they looked at past studies on alien plants that had examined how much such plants suffer from the

★depredations[6] of herbivorous insects, they found that the extent of the damage reported was significantly correlated with the number of native species with which that alien shared its principal chemical weapon.

猜测因而得到了证实。40%以上的入侵物种含有一种土产植物所没有的化学物质，仅10%多一点的非入侵外来物种含此物质。而且，他们在看了以前一些关于外来物种的研究（已经查实这类植物受食草昆虫的损害程度）之后，发现损害程度与土产植物的数量密切相关，而外来物种所含的主要“化学武器” 与这些土产植物相同。

For alien plants, then, the real secret of success—also as in human warfare—is surprise. （5）?It is not that the chemicals concerned are more toxic in any general sense? (indeed, successful invaders are often rare in their own native habitats). R_______⑩, it is that the locals just don't see them coming.

那么，对于外来植物而言，其成功的真正秘诀——人的竞争也是如此——令人感到惊奇，它不在于一般意义上所认为的那样具有毒性更强的化学物质（的确，入侵成功的外来物种在其原有生长区域内往往很罕见），而是因为本地掠食者根本没有察觉它们的到来。

NOTES：

[1]Bilology Letters 《生物书简》杂志

[2]pop up =happen suddenly, arise 突然出现，突然发生

[3]hitch v.搭便车：He hitched across Europe.他搭便车横跨欧洲。/Let’s hitch a ride.让我们搭一次便车。

[4]go bananas （口语）发疯，神经错乱

▲辨析▲——top banana 与 go bananas

top banana 本指喜剧的主角（ chief comic ），现在多半都指老板或上司（ boss or supervisor ）。

例如： He is a top banana in this corporation. （他是公司的老板。）

但是 go bananas 系指激动、疯狂、神魂颠倒（ wild, crazy or excited ）（ banana 要用复数。）

例如： The drugs （ marijuana ） have made him go bananas. （毒品大麻使他神魂颠倒。）

此外， to drive （ someone ） bananas （或 nuts ）意思也是使人发狂，只是动词要用 drive, banana 也要用复数。

例如： He has driven his wife bananas （ nuts ）（他逼得他太太发疯。）

[5]rub along （with）（跟某人）关系维持得不错；相处得不错：My wife and

I seem to rub along (together) all right.我太太和似乎相处得还不错。

[6]depredation n.（常复数）抢夺，劫掠，蹂躏：The depredations of war/of the storm can still be seen several years after the event.战争/暴风雨蹂躏的痕迹，事后数年仍历历在目。

★★BACKGROUND★★

外来物种（Alien species）是指出现在其过去或现在的自然分布范围及扩散潜力以外（即在其自然分布范围以外，在没有直接或间接的人类引入或照顾之下而不能存在）的物种、亚种或以下的分类单元，包括其所有可能存活、继而繁殖的部分、配子或繁殖体。当外来物种在自然或半自然生态系统或生境中建立了种群，改变或威胁本地生物多样性的时候，就成为外来入侵种（Alien invasive species）。外来物种在有的文件中也称之为非本地的（non-native）、非土著的（non-indigenous）、外国的（foreign）或外地的（exotic）物种。

It was a voiceactivated home assistant powered by AI(人工智能). And it made Brooke's wishes come true. A few days later, much to her parents' surprise, a $170 dollhouse and four pounds of cookies showed up. They ate the cookies and gave away the dollhouse to a local hospital. And that's not the end of the story. When a news reporter told the story of what happened on TV, Alexa devices(设备)in many listeners' homes woke up and tried to order dollhouses! Alexa isn't the only AI willing to serve you. Apple Homepod has Siri, Google Home has its Assistant, and the upcoming Galaxy Home device will have Bixby. People who have these devices use them mainly for listening to music, checking the weather, and setting timers. According to a report from The Information, nowadays voice shopping is rare. But many scientists predict a boom(增长) in voice shopping in the near future. Is that a good thing ________. You can shout out an order as soon as you think of it, even if you are cooking, cleaning, o r driving. In addition, people with disabilities who are unable to use a keyboard or mouse can shop without any help. But voice shopping has its disadvantages. Unwanted dollhouses aren't the biggest problem. It's usually very easy to cancel an order or return products. The thing t hat worries some people is that these assistants are always listening. They have to be able to respond when you want them. So they listen for “Alexa” or “OK Google” or another order. When they hear it, they start recording the conversation. Some have worried about what happens to these recordings. Should companies be allowed to use them to learn about people's shopping habits And what if someone hacks(入侵) the device The CIA found a way to hack smart TVs to turn them into spies that listen all the time. Others could do the same with any smart device. What do you think Are you ready to start voice shopping ( )1. From the passage, we know that Alexa ________． A. can look after the baby B. can cook delicious food C. is a toy doll sold online D. is one kind of AI device ( )2.

Central banks 各国央行 Brave new words 大胆新言论 Rich-world central banks explore more doveish strategies 发达国家央行探索更加温和的政策 FOR four years rich-world central banks have done their best to rejuvenate economies with conventional and unconventional monetary policy. Now, with short-term interest rates still stuck near zero and their balance-sheets stuffed with government bonds, the central banks of America, Britain and Japan are experimenting with a shift in approach: coupling monetary action with commitments designed to alter the public’s expectati ons of interest rates, inflation and the economy. The sense of change is reinforced by the prospect of new leaders at the Japanese and British central banks, and the increasing prominence of several doves at America’s. 4年来，发达国家央行为经济复苏想尽了一切办法，常规和非常规货币政策你方唱罢我登场。时至今日，短期利率依然近乎于零，资产负债表上依然满是政府债券。美国、英国和日本央行正在尝试改变路线：为了改变公众对于利率、通胀和经济前景的预期，他们做出一系列承诺，并将货币政策与承诺相结合。日本和英国央行新领导人即将走马上任，加上美国几位鸽派人物的声音日益突出，使改变即将到来的感觉愈发强烈。 A more doveish stance would entail tolerating higher inflation, at least temporarily, in pursuit of higher output: a significant shift given the primacy central banks have long given to low inflation. Bond investors have begun to price in higher inflation (see chart). But just how far each central bank is prepared to go is still uncertain. 为了提高产值，更加温和的政策意味着必须要容忍更高水平的通胀，至少短期内会是如此：央行长期以来将低通胀率视为第一要务的政策即将迎来重大改变。一些大胆的投资人已经开始以更高的通胀率定价（见图）。但是各国央行的新政力度到底有多大尚不得而知。 In Japan, Shinzo Abe, the prime minister, has used the term “regime change” to describe the Bank of Japan’s (BoJ’s) agreement to raise its inflation targe t to 2% from 1%, and pursue it with unlimited asset purchases. There are expectations for even more forceful action once Masaaki Shirakawa, the current governor, and his two deputies depart on March 19th. Under Mr Shirakawa the BoJ bought lots more assets, but critics said he undercut the positive impact by repeatedly saying they were not enough to end deflation and by restricting the maturity of bonds the bank bought. 日本首相安倍晋三曾以“制度改革”一词来形容日本央行的政策变化。日本央行同意将通胀目标从1%提高到2%，并表示为了实现这一目标资产收购将不设上限。有人预期现任行长白川方明和两位副行长3月19日离任之后，会有力度更大的政策出台。白川在任期间日本央行购入了大量资产，但是有人批评到，由于白川经常强调购入的资产数量仍不足以结束通货紧缩，而且对买入债券的期限种类

Passage1 As the host city of the next Winter Games,Beijing held a wonderful eight-minute show at the closing ceremony of the 2018PyeongChang Winter Olympics on Sunday,sending a warm invitation to the whole world. The show was directed by Zhang Yimou,a famous Chinese director who was also responsible for the eight-minute summer handover in Athens in2004as well as the opening and closing ceremonies in Beijing in2008that had a big success in the world. Unlike Athens which focused on showing Chinese history with traditional culture like red lantern and jasmine(茉莉花),“Beijing8Minutes”gave special importance to the Chinese people’s sincere welcome to the world by using modern technology. Leading the team were two dancers in costumes of panda puppets that are the world’s largest but the lightest at the same time,each weighing only about10kilograms.To reduce the pressure on the two dancers,researchers had tried hundreds of different materials until ending up with high-technology ones.

空气污染英国需要采取更多措施来净化污浊的空气 Air pollution空气污染The big smoke雾都 Britain needs to do more to clean up its dirty air 英国需要采取更多措施来净化污浊的空气VISITING Oxford Street, a road teeming with tatty shops and overcrowded with people, is plainly a trial. Less plainly, levels of nitrogen dioxide (NO2), a noxious gas, have been found to be around three times higher there than the legal limit. In 2013 the annual mean concentration of NO2 on the street was one of the highest levels found anywhere in Europe. 来到牛津街，你会看到街道两边布满了各式杂乱的商店，而道路上人满为患。行走在这条街上，很明显是个磨练。不为人觉察的是，这里有毒气体二氧化氮(NO2)测出含量超出法定水平的约三倍以上。２０１３年，这条街的NO2年均浓度是欧洲最高之一。 British air is far cleaner than it was a few decades ago. Fewer people use coal-burning stoves; old industrial plants have been decommissioned. But since 2009 levels of nitrogen oxides and particulate matter, coarse or fine particles that are linked to lung cancer and asthma, have fallen more slowly. The exact number of deaths caused by dirty air is unknown. But in 2010 a government advisory group estimated that removing man-made fine particulate matter from the atmosphere would increase life expectancy for those born in 2008 by an average of six months. 英国的空气比几十年前干净多了。使用燃煤炉灶的人越来越少；老工业厂已经停产。但自2009年起，氧 化氮、微粒物质、以及与肺癌和哮喘相关的粗、细颗粒含量的下降速度减慢了。因污浊空气所引发的死亡人数是未知的。但2010年，一个政府顾问组估算如果将大气中人为造成的微粒物质除去的话，2008年的出生人口人均寿命将增加六个月。 Much of the slowdown is the result of fumes from diesel cars, which were championed by successive governments because they use less fuel and thus produce less carbon dioxide than petrol cars. In 2001 only 14% of all cars ran on diesel; by 2013 the proportion had increased to 35%. (Greener “hybrid” and electric cars have increased ninefold since 2006, but account for just 0.5% of the entire fleet.) Second-hand cars are particularly noxious, but even newer ones have not been as clean as hoped. Many cars that belched out few pollutants in tests produced more when on the roads. 下降速度放缓的大部分原因在于柴油汽车排放的尾气—这为历任政府所支持，因为柴油汽车耗用更少的能源，比汽油汽车排放更少的二氧化碳。2001年，仅14%的汽车使用柴油。2013年，这个比例上涨到了35%。（更绿色的“混合动力”和电瓶车自2006年以来增加了九倍，但仅占汽车总量的0.5%。）二手汽 车尤其有害，但新车也没所期望的那样清洁。很多车在污染物排放测试中排放量低，车在上路时却排放了更多。 Climate change and geoengineering气候变化与地质工程学Fears of a bright planet 地球发光，令人担心Experiments designed to learn more about ways of geoengineering the climate should be allowed to proceed为更好地利用工程学手段研究气候问题所设计的实验应该获准进行下去。SHINY things absorb less heat when left in the sun. This means that if the Earth could be made a little shinier it would be less susceptible to global warming. Ways to brighten it, such as adding nanoscale specks of salt to low clouds, making them whiter, or putting a thin haze of particles into the stratosphere, are the province of “geoengineering”. The small band of scientists which have been studying this subject over the past decade or so have mostly been using computer models. Some of them are now proposing outdoor experiments—using seawater-fed sprayers to churn out particles of the exact size needed to brighten clouds, or spewing sulphur particles from underneath a large balloon 20km up in the sky.发光的物体放在太阳下面会吸收较少的热量。这就意味着如果让地球发一点光的话，受到全球变暖的影响就会小一些。让地球发光的方式，比方说在低空云层上添加纳米级的盐微粒，让云变得更白，或者是将一层薄的雾状物洒向平流层，这些都属于地质工程学的范畴。过去十年左右研究这一领域的一小批科学家主要使用计算机模型，其中一些人现在提出要做室外实验――就是用装有
