Fatal Attraction

They lure insects into death traps, then gorge on their flesh. Is that any way for a plant to behave?

From National Geographic
Size doesn’t ensure success. If a gluey tentacle grabs too little of a big fly, the bug may suffer injury but still struggle to freedom. In the realm of carnivorous plants, says William McLaughlin, curator at the United States Botanic Garden, “some insects aren’t digested but are still victimized.”

大小不能决定捕食的成功率。如果粘稠的触须只粘到了大苍蝇的一小部分,那么这只苍蝇也许会受伤,但还是能够重获自由。美国植物园园长,William McLaughlin说,在肉食类植物的王国里,“有些昆虫虽免于殉命,但难逃受伤的厄运。”

Nepenthes alata


From National Geographic

A hungry fly darts through the pines in North Carolina. Drawn by what seems like the scent of nectar from a flowerlike patch of scarlet on the ground, the fly lands on the fleshy pad of a ruddy leaf. It takes a sip of the sweet liquid oozing from the leaf, brushing a leg against one tiny hair on its surface, then another. Suddenly the fly’s world has walls around it. The two sides of the leaf are closing against each other, spines along its edges interlocking like the teeth of a jaw trap. As the fly struggles to escape, the trap squeezes shut. Now, instead of offering sweet nectar, the leaf unleashes enzymes that eat away at the fly’s innards, gradually turning them into goo. The fly has suffered the ultimate indignity for an animal: It has been killed by a plant.

Facts can be so misleading, where rumors, true or false, are often revealing.
——《Inglourious Basterds》

Of course, I don’t totally believe the story  below, and it was written by a foreigner with his own point of view, which could be very subjective; but neither can I trust the government’s reports, because they covered up many details. As I think, if it is a rumor, we should stand out to expose the lie; if not, we certainly have the right to know the truth. So even rumors provide a perspective. The more we hear about them, the better we could know how to distinguish them.

I am merely an apprentice for translation, and I bring this article to you. Now it’s your turn to read and think it. Remember,

Think wrongly, if you please, but in all cases think for yourself.

Last but not least I’d like to dedicate this work to yeeyan for it has once helped me a lot.


The Other Tibet

The Uygurs, Muslim people of China’s resource-rich far west, are becoming strangers in their own land as Han Chinese pour in. Like the Tibetans, who face similar pressures, some Uygurs see a chance for a better life, but others protest the disintegration of their culture, even at the risk of death.

The first several seconds of the incident in Urumqi seemed almost lighthearted, considering the previous week. And they revealed nothing about what would follow. A cool front had swept over the city on this particular day in July, drawing people from their homes. Some shops stayed closed because their windows had been shattered, but food vendors pushed their carts out onto the street. A week earlier an ethnic clash had broken out here, killing almost 200 people in one of China’s most deadly protests since the Tiananmen Square massacre two decades ago. So the Chinese government had sent tens of thousands of security forces into the city, the capital of the Xinjiang Uygur Auton omous Region, to restore order between the Han and the Uygurs. The Han dominate Chinese society, but the Uygurs (pronounced WEE-gurs), a Turkic-speaking Central Asian people, claim this western borderland as their ancestral home.

Three leaf-litter toads collected within yards of each other almost disappear on a forest floor in Panama. Staying alive in the tropics, where nearly everything is food for something else, often calls for such trickery to fool a predator’s eye.

The Art of Deception

Sometimes survival means lying, stealing, or vanishing in place.

When Macbeth was told he had nothing to fear until the local woods started ambling up to his castle, the tyrant sighed with relief, for “who can impress the forest, bid the tree unfix his earth-bound root?”

直到树木开始缓缓攀上Macbeth的城堡时他才开始感到恐慌,这位暴君轻叹一声,聊以自慰道:“谁能迫使森林俯首听命,强令树木拔起自己深植的根?”(本博主注:没读过莎士比亚《Macbeth》,不知道所指何意,不过句子写得很拽。我猜主要是强调《Macbeth》里树木会动,与后文各种生物伪装成植物,所以看似“植物”也会动相关联。另外,《V for Vendetta》里V也引用过《Macbeth》中一个句子:I dare do all that may become a man; Who dares do more is none.)

Macbeth obviously had never been to Barro Colorado Island in Panama.

显然,Macbeth从没去过巴拿马的Barro Colorado岛。

It is 9 p.m. and as dark as a witch’s mummy, but in the cone of light cast by my headlamp, parts of trees seem to be unfixing themselves and wandering at will. A four-inch twig buzzes overhead and thuds onto a nearby branch. A lime green leaf scratches through a pile of brown leaves, finds nothing of interest, and crawls toward another pile.


I approach the migrants for a closer look, knowing full well what they are but still dazzled by the details, by the almost comical earnestness of the charade they embody. The “twig” is a stick insect, a magnificent specimen of the Phasmatodea clan, its outer sheath a persuasive rendering of striated bark, its tubular body and head punctuated by fake axillary buds and leaf scars—the little knobs and notches that make a twig look twiggy.


During the day these insects move little and are nearly impossible to distinguish from the sylvan backdrop they imitate, and that, of course, is the point: to remain invisible to sharp-eyed predators that use vision to hunt. Come nightfall, however, sticks and leaf katydids shake off their vegetal torpor to do some feeding of their own—on leaves and forest-floor detritus—at which point their ancient artifice can be admired by grace of our modern artificial lights.


We are drawn to mimicry and disturbed by it too. As children, we play dress up and let’s pretend, and we understand our fellow hominins through private reenactment. Our most elaborate masquerades—for Halloween, say, or the Day of the Dead—are often tangled up with our deepest fears. What self-respecting Hollywood slasher would be seen without his Munchian mask or mother’s wig?


Mimicry in nature likewise can charm or repel us, but whatever our human judgments, this much is true: Scamming works, and the natural world abounds with P. T. Barnums, which fill every phyletic niche, sucker every sense. Biol­ogists have barely begun to tally life’s feinting legions or trace the evolutionary and genetic details of each imposter’s disguise. Sometimes the deception serves as camouflage, allowing its bearer to elude detection by predators, prey, or quite often both: In Panama I found a mantid that looked like a few sprigs of radicchio, the perfect cloaking device for a stealth hunter of leaf-eating insects that is itself much coveted by insectivorous reptiles and birds. At other times the swindler wants its merchandise to be noticed; that’s the whole point. An anglerfish wags its head until its fleshy protuberance shimmies like a worm and baits other fish. Carrion orchids sprout large, purplish, fetid blossoms that look and smell like dead meat to attract scavenger flies, which will alight on the flowers, get dusted with pollen, and maybe, just maybe, help the orchid breed.

自然界中的各种伪装术既吸引我们也恐吓我们,但不管我们怎么看,有一点是千真万确的:自然界中的每个角落里都充斥着吓人的把戏和逼真的表演,欺骗无所不在(原文此处提到P. T. Barnum,关于此人的介绍请参见wiki,点这里。简单说来,他说过这样一句话 : There’s a sucker born every minute. 即笨蛋无处不在。其言下之意就是说人是很好骗的。p.s : 不过此句的语法有误。本博主注)。生物学家们对生命的种种伪装现象,对伪装者的进化和基因细节的记录和追踪才刚刚起步。有时,伪装术是一件隐身衣,穿上它可以不被掠食者或者猎物(经常是兼而有之)发现:在巴拿马我发现一种长得很像菊苣(莴苣)枝叶的螳螂,无论是对自己垂涎欲滴、酷爱捕食昆虫的爬行动物和鸟类,还是作为悄无声息的食叶类昆虫杀手而言——这身着装都堪称完美。在其他情况下,这些骗子希望自己的鬼把戏被注意到;这其实是辩证统一的。琵琶鱼会摇头晃脑,让它头上的肉瘤看起来像条虫子,并等着其他鱼上钩。腐肉兰花会开出很大且带有阵阵恶臭的紫色花朵,看起来、闻起来都很像死肉,食腐的苍蝇会被吸引过来在花上停留,并因此沾上花粉,也许会帮助兰花播种,记住,这仅是也许而已。

A finger-length katydid disguised as lichen-coated bark barely registers in the dim understory of a Panama forest. But camouflage is more than just looks—the wearer must also act the part. This nocturnal insect holds stock-still during daylight hours to help conceal its contours.


From Drop Box

The sensory form that an act of mimicry takes varies according to the sensory talents of the mimic’s target audience. Most familiar to us visual primates are the visual mimics, the ones adapted to fool the eye, like the riparian frogs that crouch in a riverbed and look as slick and round and inorganic as the polished stones around them, or the caterpillar that, when frightened, will hold up its front end to flash a fluorescent salmon pink face with a pair of scary snake eyes. But there are vocal mimics too, like a palatable species of tiger moth that deters bats by parodying the ultrasonic clicks of a toxic moth the bats detest, or like the greater racket-tailed drongo of Sri Lanka, which mimics the calls of other birds to drum up a mixed-species flock in which the drongos can more safely and efficiently forage.


Then there are olfactory mimics, such as that mad parfumier the bolas spider, which can lure male moths by secreting perfect knockoffs of the counterpart females’ eaux de toilette. There are even tactile mimics, including a parasitic fungus that lives in the inner chambers of termite mounds, where it is kept warm, moist, and competitor free. Termites are notoriously zealous housekeepers. How does the fungus elicit indulgence rather than expulsion? By assuming the shape and texture of ripe termite eggs.


Mimicry fables can sound like O. Henry stories, offbeat dilemmas dapperly resolved. For example, caterpillars are voracious eaters. They chomp their way through many leaves in their lifetimes. Birds love fattened caterpillars, and as they fly overhead, they search for signs of caterpillar activity, most notably damaged leaves. To thwart the aerial reconnaissance, one species of caterpillar has adopted a novel dining style. Rather than tearing through foliage at random, the Geometridae caterpillar cuts its leaves deftly, mincingly, moving along the edges like a seamstress with her scissors, in and out, zig and zag. By the time the caterpillar is done, the leaves may be much smaller, but their borders maintain their maiden serrated form.


Sometimes the best offense is a ghoulish pretense. Reporting recently in the Proceedings of the National Academy of Sciences, Leslie Saul-Gershenz and Jocelyn Millar described the case of the abominable blister beetle and the benighted solitary bee. Blister beetles live in the southwestern deserts of the United States. Females lay their eggs in grassy patches where solitary bees forage. The beetle eggs all hatch simultaneously, and the thousand or so newborn larvae immediately gather together into a tight formation. They form a nice oval shape, all dark and fuzzy. They travel as an inseparable unit, up and down the blades of grass. They look and act just like—a female solitary bee. Before long, they start releasing a pheromone mimic, and now they smell like a female bee too. A male bee lands on what he thinks is a mate, and the blister pack clings to him en masse. Disappointed by the encounter, and seemingly unaware of his cargo, the male bee flies on in search of new love. Should he find and approach a real female bee, the beetle larvae will instantly abandon him and cling to her. The female will take them where they want to go, back to her well-provisioned nest. The larvae will deplane, settle down, and gorge themselves to maturity on nectar, pollen, and, best of all, the bee’s eggs.

令人毛骨悚然的伪装有时是最好的攻击手段。在《Proceedings of the National Academy of Sciences》(国家科学学术系列报道)的最新报道中,Leslie Saul-Gershenz 和Jocelyn Millar向我们描述了讨厌的斑蝥(老规矩,长相请参见wiki,点这里。本博主注和善良的独居蜂(老规矩,长相请参见wiki,点这里。本博主注之间的故事。斑蝥生活在美国西南部沙漠。雌性斑蝥将卵产在有独居蜂觅食的草地上,这些卵会同时孵化出来,然后这成千上百的新生幼虫立即聚集起来,紧紧地团成一块。它们呈一个规则的椭圆形,黑乎乎、毛茸茸的。它们作为一个密不可分的整体一同行动,在草叶上上下移动。无论外观和行为上,它们看起来都和一只雌蜂无异。不久之后,幼虫开始释放信息素来伪装自己,现在它们连闻起来都和雌蜂一样了。一只雄蜂以为找到了配偶,于是停落过来,这时幼虫们一起附着了上去。雄蜂对这次的相遇非常失望,于是又飞往他处去结识新欢了,而它却好像没有意识到自己已经带上了“货物”。一旦它找到并靠近了一只真正的雌蜂,斑蝥幼虫会马上弃它而去,转而附着到雌蜂上。雌蜂会带着它们去它们想去的地方——回到雌蜂供给丰富的蜂巢。幼虫们、于是下机住了下来,这里有花蜜、花粉,还是最好的一样东西——蜂卵,这些可以供它们狼吞虎咽,直到它们成熟为止。

Of course, even the most cunning of nature’s caricatures have no narrative mastermind behind them. Mimicry exemplifies evolution by natural selection, the relentless struggle in which parents spawn a diversity of offspring that chance and nature’s cruel eye for weakness shear almost clean away. If your slight resemblance to bird dung gives you enough of an edge that you survive to breed, your progeny may inherit your lucky guano cast. Maybe one will even top you as a droppings imposter, and within a few hundred generations the trait will have spread through the whole population and be the gold standard for your kind.

当然,即便是对大自然最精妙的模仿,其背后也不是有什么人在出谋划策。伪装术是对物竞天择下的生物进化的一种典型诠释,生物进化过程中充满了残酷无情的斗争,父母会产下很多特点迥异的后代,而机会从不会留给羸弱者,大自然的双眼冷冷地盯着那些不完美的成品,几乎将它们消灭地一干二净(这句是我认为最难翻的,高人指点下才有些眉目,主要是要注意句子结构。the relentless struggle…是evolution by natural selection的同位语,看不清这点后面就都看不懂了。而in which parents spawn…这些都是在对the relentless struggle做补充说明。本博主注) 。如果你有那么一点长得和鸟屎相似,并刚好因此而得以存活下来,繁衍生息,那么你的子嗣就可能已遗传到你狗屎运般得来的装屎术。甚至可能有人把你推崇为屎形秀第一人,随后经过数百代的遗传,这个特征将遍及到你的子子孙孙中并成为你们一族的黄金生存法则。(这一段实在太恶搞了,原来NG的文章都会出现这么恶搞的文风啊。。。本博主注。)

Resembling flora more than fauna, a female walking leaf of Malaysia stems from a long line of extreme leaf mimics. This insect group is little changed over 47 million years, judging from a recent fossil find in Germany. The largest of thousands of leaflike species, Phyllium giganteum can unfurl to some four inches in length.

长久以来祖先对树叶惟妙惟肖地模仿被一只马来西亚的雌性叶科昆虫继承了下来,这使得它看上去更像植物而不是动物。从最近在德国找到的一块化石来判断,这类昆虫在470万年间都没有发 生什么变化。作为数千类叶状动物中体型最大的那种,叶虫(Phyllium giganteum)伸展开来可以达4英寸长。

From Drop Box

Mimicry also reveals just how messy evolution can be, how ad hoc and make-do. For example, Ximena Nelson and Robert Jackson report in the Proceedings of the Royal Society on the dilemma of the male Myrmarachne, a jumping spider. Like a number of the world’s jumping spiders, these arachnids have evolved to look like ants, a strategy that plays into the antipathy many predators have for the aggressive, noxiously armed, and ecologically dominant social insects. But the male spiders have a problem with the basic strategy, for mating rituals demand that they sport elongated mouthparts, which could detract from the overall antlike effect. Evolution has hammered out a compromise: Whereas the female spiders look like ordinary ants, the males with their enlarged fangs have come to resemble ants carrying bundles in their mandibles, as worker ants sometimes do. Ingenious, yes, but not perfect. It turns out that although the male jumping spiders are as effective as their female counterparts at deterring the generally ant-phobic among hunters, the males alone fall prey to predators that target ants least likely to fight back—those encumbered with bundles.

伪装术也同样揭示出生物进化可以是多么的糟糕,能将就就将就,能凑合就凑合。举例来说,Ximena Nelson和Robert Jackson在《Proceedings of the Royal Society》(皇家社会系列报道)中讲述了一种雄性跳蛛的窘境。和世界上相当一部分的跳蛛一样,这些蛛形纲生物进化得看起来和蚂蚁一样,它们采取的是一种与其他掠食者截然不同的战略,多数掠食者极富攻击性,武装得凶神恶煞,在生态链上主宰着群居类昆虫。但雄蛛在实行这个战略上有一点点小问题,因为在交配仪式上雄性会被要求炫耀和展示它们细长的口器,这会让雄蛛表现得不那么像蚂蚁。生物进化于是做出了这样的妥协:雌蛛看起来和普通蚂蚁一样,而雄蛛将它们大牙伪装得像用下颚在搬运一捆捆东西的模样,工蚁有时候就是这个样子的。不可否认,这个方法很天才,但却并不完美。事实证明虽然雄蛛和雌蛛一样,能有效的吓阻那些一看到蚂蚁就心生恐惧的猎手,但是当雄蛛落单时它就会沦为捕食者的猎物,这些捕食者通常更喜欢攻击那些无力反击的目标,而最无力反击的正是那些拖着一捆捆东西的蚂蚁。

Scientists are particularly intrigued by imperfect mimicry, where one organism only vaguely resembles another. In some cases, the crude form may indicate a lineage newly embarked on the mimicry path, when evolution has only begun to hone the simulation. In other instances, the disjunction is a result of the mimicked species pulling away from its unwanted copycats. If the warning colorations that you have evolved to advertise your hard-won unpalatability are mimicked by too many edible free riders, your brand name will be cheapened and lose its protective value.


Mimicry can also be a great way to preen, or learn, or make a new friend. Among songbirds and humpback whales, competing males seem to imitate each other’s songs. And some dolphins duplicate each other’s flying leaps. Parrots are masters at parroting, and ape is what the great apes do, which is why orangutans can learn to cook pancakes and chimpanzees to hunt with tools, and we compare each other to a summer’s day and mirror each other’s joy with a smile.

伪装术也可以是一种很好的炫耀,学习和交友的方式。在鸣禽或者座头鲸之间,雄性相互竞争的手段似乎是模仿对方的叫声。另外,一些海豚还模仿对方跃出海面飞跃时的姿势。鹦鹉和大猩猩都是模仿大师,这就是为什么大猩猩可以学会煎煎饼,黑猩猩能够用工具捕猎,而我们会互将对方视作明媚的阳光(”compare… to a summer’s day”,这个词是有出处的,借用莎士比亚的一个句子,原话是:Shall I compare thee to a Summer’s day. 老外的文学素养好高啊,叹服。。。本博主注)并和对方一样开怀大笑。

Leaf knockoffs down to brown spots and notched edges, two Mimetica katydids with twiglike legs can rest or feed without drawing attention. Still, their best efforts at blending in sometimes fail. Fleshy, protein rich, and toxin free, katydids are avidly sought and caught by keen-eyed monkeys, birds, lizards, frogs, and snakes.

Show Two Faces
An extra pair of eyes, even phony ones, can be a boon to insects hunted by predators that target by sight. A saw-nosed plant hopper’s first defense is camouflage.But if a bird, lizard, or other hunter takes aim, the saw-nosed plant hopper can startle its foe by unveiling red spots that could be mistaken for the eyes of a larger animal.

有些捕食者根据外表选择猎物,对于被它们所追逐的昆虫们来说,多出一双眼睛,即使是一双假眼睛,也是一种恩赐。锯鼻飞虱(saw-nosed plant hopper)的第一重防御便是伪装。但是如果一只鸟,或者其他猎捕者还是紧盯它不放,锯鼻飞虱会让它们吓一大跳——方法是露出一对红斑,这对红斑会被误认成一只更大型动物的眼睛。

Show Two Faces

A butterfly pupa, a species discovered in Costa Rica by Daniel Janzen of the University of Pennsylvania, also shows a false face. “Peering” from a rolled-leaf shelter, its eyespots may deter small birds exploring the foliage for insect prey. Though a prevalent ploy in nature, the fake-eye look isn’t foolproof. Animals that get caught may have secondary defenses, like a foul taste or toxic secretion. The plant hopper takes a more spirited approach, buzzing like a stinging wasp to provoke a quick release.
“蝶蛹(butterfly pupa)”——宾夕法尼亚大学的丹尼尔·简森(Daniel Janzen)在哥斯达黎加(Costa Rica)发现的一个物种——也有一张假脸。住在一张卷起来的树叶里,它从中“探出一双眼睛”,对于那些在层层树叶中探索昆虫的小鸟,它的眼斑可以起到威慑作用。虽然这是自然界一个比较普遍的伎俩,但“假眼策略”看起来也不是万无一失的。被捕获的动物们可能有第二重防御,例如散发出异味或分泌出毒素。飞虱则采用了一种更聪明的方式——模仿蜇人的黄蜂常发出的嗡嗡声,吓得对方忙不迭地放手。

Cryptic coloration and a shape like a leaf spine help shield a tropical Geometridae caterpillar, but its feeding behavior is the master stroke. By munching along a leaf’s scalloped contours and keeping the edges well-balanced left to right, “it disguises the damage that could clue a predator to its whereabouts,” says University of Utah biologist Phyllis Coley. For such a nondescript little inchworm, she says, “it’s pretty sophisticated.”

保护色和如叶脊般的形状能够帮助一只热带尺蛾(Geometridae)毛虫隐蔽它的行踪,但是更为高明的是它的摄食动作。沿着叶片的扇形轮廓下嘴,同时保持叶子左右两半的边缘对称。“它通过掩饰叶子的受损情况来避免捕食者追踪到它的下落。”犹他大学 (University of Utah)的生物学家菲利斯·康利(Phyllis Coley)说道。她说,这么一只不起眼的小尺蠖可是非常的不简单。

Modeling fake parts and elegant disguises, many caterpillars keep their enemies guessing. A silk moth caterpillar comes with a false head, complete with mock antennae, to lure predators into biting its rear. Plan B: If the ruse fails, extra spines on the real head may prompt the attacker to spit out its prey still intact.

For one nematode parasite, the goal is not to escape, but to be eaten. When it hijacks an ant, it turns its host’s back end as red and prominent as a ripe fruit. “This likely dupes a bird into feeding on it and getting a mouthful of nematode eggs,” says ecologist Steve Yanoviak. The bird spreads the eggs via its feces, which the ants eat, continuing the cycle.

对于一条线形寄生虫来说,其目的可不是逃跑,而是被吃下去。当它寄生于一只蚂蚁身上时,它会将它宿主的屁股变得像一个成熟的果子一样又红又显眼。生态学家史蒂夫(Steve Yanoviak)说:“这可能能骗得一只鸟把它吃掉,然后这只鸟就吃下了一肚子的线虫卵。” 然后这只鸟通过排便四处散播这些虫卵,而蚂蚁又吃鸟粪,于是就形成了一个循环。

Get Noticed
In frogs, conspicuous colors often signal toxicity. But a species on islands off Panama doesn’t stick to a single color signal. That’s counterintuitive, says Martine Maan of the University of Texas at Austin, “We’d expect the frogs to look similar so predators could easily learn to associate toxicity and coloration.” But another selective force is in play. Females on different islands have developed tastes for mates of different colors, probably driving male hues to diverge instead of merge. Still, the poison alarm seems effective. Most predators likely just avoid vivid frogs, Maan says, a precautionary tactic for a perilous world.
对于蛙类来说,醒目的颜色往往是有毒的信号。但是,在巴拿马的群岛中,有一种蛙并不局限于发出单一颜色的信号。这是反常 的,得克萨斯大学奥斯汀分校(University of Texas at Austin)的马汀娜·马安(Martine Maan)说:“我们以前认为,如果蛙都同色,会使得其天敌很容易地将毒性和颜色联系起来。”但另一种决定性力量在起作用。不同岛屿上的雌蛙已经培养出对 不同颜色的配偶的倾好,这可能使得雄蛙的颜色各异而不是相同。但是,有毒警告似乎仍是有效的。马安说,大多数捕食者可能遇到颜色鲜明的青蛙就避开,这是在 一个危险的世界采取的预防性策略。

As Royal Society Fellow Richard Bradley wrote in 1759, “The insect is nourished by the juices of the tree … and at the fall of the leaf, drops from the tree with the leaves growing to its body like wings, then walks about.” The description “may seem comical with hindsight,” says Edward Baker of the Natural History Museum of London, “but the fact is, we still know very little about the biology of the majority of these species.”
即使是眼睛和触角也很难将这只叶虫(Phyllium giganteum)的头部暴露出来。早期的植物学家认为,叶科昆虫真的和它们所模仿的树叶结合在了一起。英国皇家学会研究员理查德·布拉德利(Richard Bradley)在1759年写道:“昆虫被树的汁液所滋养…树叶就像翅膀一样长入了它们的身体里,随着树叶飘落,它们也掉落地面,然后四处游荡。” 这段描述“在后来看来,似乎有点可笑,”伦敦自然历史博物馆的爱德华·贝克(Edward Baker )说,“但事实是,对这些物种的大多数生物的生活规律,我们仍然知之甚少。”

这是NG 8月份的一篇文章(7月中旬其实就已经开始翻阅),能拖到现在才发实在是才疏学浅,翻译地痛苦、校对地痛苦、排版地也痛苦,可还是像有些人说的 : 没那范儿。那怎么办呢?凉拌呗,自娱自乐。其实是骑虎难下,这是NG 8月刊里最短的一篇文章,图片几乎比文字还多,这才让我有了冲动。实际一动手才发现不是那么回事,原本还想着每个月都这么整一篇的呢,如今看来对我而言实在是很有难度,尽力折腾吧。

What doesn’t kill us makes us stronger. Keep working, keep walking~



Clusters of Khmer homes , perched on spindly stilts to cope with flooding during the summer monsoon, dot the landscape from the Tonle Sap, the “great lake” of Southeast Asia, some 20 miles to the south, to the Kulen Hills, a ridge jutting from the floodplain a roughly equal distance to the north.

高棉人的房屋由一根根细长的柱子支起以应对夏日季风来临时的洪水,它们簇拥在一起正好将陆上的风景与Tonle Sap(东南亚著名的湖泊)相区别,Tonle Sap距离Kulen山以南20英里左右,而Kulen山的山脊横贯整个泛滥平原 ,大致将其南北平分开来


句子其实是这样:Homes dot the landscape.

再稍微扩展一下:Homes dot the landscape from the Tonle Sap to the Kulen Hills.

这下看起来就很明朗了,句子中的其他部分都可以看成是同位语,在修饰各自的名词部分,我起先完全没有把握住句中地点状语部分的 from…to… 句式。

高棉人的房屋由一根根细长的柱子支起以应对夏日季风来临时的洪水,它们成群的散布在从Tonle Sap湖一直到Kulen山之间广阔的土地。 Tonle Sap–东南亚著名的湖泊,距离(吴哥窟)以南20英里左右;Kulen山–一座径直插入泛滥平原的山脉 ,在(吴哥窟)以北大致也是20英里左右的地方。

p.s 2 : 李笑来老师的讲座果然很吸引人,对不起我的词汇很贫乏,如果你有更华丽的词藻,尽可以往上加。对此人不了解的,我强烈建议你关注这个网站。这是我google reader里读的最多的博客之一(另一个是孔庆东老师的博客)。是的,再次强烈建议你关注。

p.s 3 : 在李老师的讲座里学到一个新词:strike home. 释义如下:
