为何被纸划伤如此疼痛?【第一篇】

Paper Cuts, Why So Painful?

为何被纸划伤如此疼痛？

Few minor injuries are as painful as the dreaded paper cut. Just thinking about it probably makes you cringe. However, these cuts are usually small, hardly noticeable, and rarely bleed. So what makes them so painful?

很少有一些小伤能够像被纸划伤那样让人疼痛和害怕。光是想一想可能就让你不寒而栗了。然而，这种划伤通常伤口很小、很难被察觉到并且不怎么会流血。那为什么被纸划伤会这么疼呢？

A paper cut is similar to a cut with a razor blade, with one major difference. A razor blade makes a smooth, clean incision in the skin, leaving behind few if any foreign particles that might cause the wound to become infected. Although it might hurt initially, the pain brought on by a small razor cut usually fades after a few minutes.

被纸划伤跟被剃须刀片划伤很像，但是有一点不同。剃须刀片造成的伤口较为平整，几乎不会留下任何会导致伤口感染的异物。虽然刚被剃须刀片划伤的时候很疼，但是过几分钟疼痛感就会慢慢消退。

Like a superficial cut by a razor blade, a paper cut smoothly parts the skin, but while a clean razor leaves little behind to irritate the wound, a paper cut deposits material that really stings.

被纸划伤的伤口和剃须刀片造成的伤口一样，也很平整。但是干净的刀片不会留下任何物质去刺激伤口，而纸划伤口却会留下一些让人感到疼痛的物质。

Paper is made of pressed wood mulch, and a variety of chemicals. When paper cuts into the skin, chemical coated fibers, as well as bacteria and tiny particles remain in the wound and stimulate pain receptors in the skin.

纸是由压缩木片和多种化学物质构成的。当纸划过皮肤时，化学涂层纤维、细菌和细小颗粒物就会留在伤口里，对皮肤里的痛觉感受器产生刺激。

Because the cut is usually small and shallow, the skin on either side of the wound closes quickly, trapping the fibers and other particles inside. The result is a good deal of pain, and since the closed wound doesn’t allow for much bleeding, the pain seems entirely out of proportion to a cut that you can barely detect.

由于伤口通常很小且很浅，伤口会很快愈合，同时会把纤维和其他粒子留在伤口里面。所以，你才会感到十分疼痛，由于闭合的伤口几乎不会流血，所以说，即使伤口小到你几乎察觉不到，但是伤口造成的疼痛感却是要人命的！

为什么要确立格林威治标准时间【第二篇】

Why Was Greenwich Standard Time Created?

为什么要确立格林威治标准时间？

Imagine getting on a train at twelve noon and heading out on a four-hour trip to another town.

设想一下：您正乘坐一辆中午12点整出发的火车前往另外一个城市，路途耗费4个小时。

You’d expect to arrive at four o’clock in the afternoon, right? But before the last few decades of the 19th century, there was no guarantee that this would happen, and it usually had little to do with slow trains or drunken conductors.

你肯定期望在下午四点能够准时到达，对吧？ 但是，在19世纪末之前，保障准确的抵达时间是基本不可能的，并且这与晚点或醉酒的列车长几乎毫无关系。

Until the end of the 19th century virtually every town across the world kept time according to its own methods, creating problems for industries such as railroads that relied on precise timing to deliver goods.

实际上，直到19世纪末为止， 几乎世界上每个城市都有自己记录时间的方式，这就给需要精确定时发送货物的行业，如铁路运输业等带来无尽的麻烦。

How To Control The Chaos

怎样控制混乱的时间

To bring order to this chaos, a conference was held in Washington, in 1884. Delegates from around the world designated Greenwich, England as the starting point from which to create international time zones.

为了让混乱的时间变得有序，各国代表于1884年在华盛顿特区召开了一次会议。代表们指定英国格林威治作为创建国际时区的起点。

But why was this small, London suburb chosen to create what became known as Greenwich Standard Time?

为什么这个伦敦郊区小镇会被选定并创建格林威治标准时间呢？

GST?

格林威治标准时间？

Over 100 years before the Washington conference, King George II of England designated Greenwich as zero degrees longitude in order to help stabilize the shipping trade. If you look at a globe of the earth you’ll see that the vertical line marked ‘zero’ that runs from the North to the South Pole- zero degrees longitude–runs directly through Greenwich.

在华盛顿会议100多年以前，英国国王乔治二世为了稳定航运业，曾将格林威治标为0度经线所在地。如果你看一下地球仪，你可以看到联通南北极的零度经线正好穿过格林威治。

By the time of the Washington conference many shippers already used the longitude system to keep time when traveling by sea. It was only natural for most countries to adopt this system as the basis for creating standard time for the entire planet.

在华盛顿会议召开之时，需要船公司在海运过程中已经使用经度系统来掌控时间。大多数国家自然就容易接受使用这一系统作为确认全球标准时间的基础。

Based on longitude increments of fifteen degrees, time becomes one hour earlier each longitude west of Greenwich, and one hour later each longitude east of Greenwich. In other words, when it’s twelve noon at zero degrees longitude, it’s one o’clock at fifteen longitude east.

以每增加经度15度为基准，格林威治每往西一个时区时间便减少一个小时，而每往东一个时区则增加一个小时。换句话说，当零度经线处是中午十二点时，东经15度处便是下午1点。

优秀英语美文文摘【第三篇】

iller on Wings Is Under Threat

飞翔的杀手正受到威胁

Could anything be more majestic, serene or threatening than the largest bird of prey in theworld, the harpy eagle, soaring above its domain? Weighing nine kilograms and with a wingspan, this giant of the .sky glides at 65 kilometres per hour over dense Brazilianrainforest. Its cruel head with flaring coloured crest and huge hooked beak twists constantlyfrom side to side.

有什么比世界上最大的食肉猛禽热带大雕在它的领地上方搏击长空更加壮丽，更加安详，又更具威胁性呢？体重九公斤，翼幅达米的空中巨物在茂密的巴西雨林上空以每小时65公里的速度滑翔。它那长着展开的有色肉冠和巨大钩状鹰嘴的残暴的脑袋木断地向两边扭来扭去。

It spots a monkey in a treetop kilometres away and zeroes in on its prey. The monkeymunches on, oblirious to the threat. Then the eagle strikes,plucking its prey from its perchwith talons bome on legs the thickness of your wrists. The monkey dies instantly, pierced bythe talons. The eagle carries the body back to its treetop lair. The famed and feared harpyeagle has killed again.

它发现了公里之外树梢上的一只猴子，就立即把注意力集中在这只猎物身上。猴子全然不知威胁的存在，仍在津津有味地咀嚼着。大雕发起了进攻，用它的利爪将猎物从树枝上一把抓了起来，那利爪长在与人的手腕一般粗的腿上。被利爪刺穿了的猴子刹时间一命呜呼。大雕将其尸体带回树梢上的窝里。鼎鼎大名、令人生畏的热带大雕又杀生了。

Whether this frightening creature does indeed soar like other eagles in search of prey is opento conjecture . Forless is known about the harpy than any other eagle-the remoteness of itshabitat sees to that. But it has been seen carrying monkeys, sloth and even small deer back toits nest.

这吓人的热带大雕捕食时是否真的和其他鹰类一样翱翔还没有定论，尚待猜测。人们对大雕的了解比对其他鹰类的了解都少——这是因为它的栖息地十分遥远而造成的，但确实见过它将猴子、树獭甚至小鹿带回巢中。

This eagle's extraordinary eyesight is one of its greatest assets. Like many other eagles, it cansee between four and eight times as much detail as canhumans. The result is an ability to seeclearly a smaU monkey at a distance of up to kilometres and to judge distances withpinpoint accuracy . The latter is an obvious requirement if prey is to be snatched at speed.

大雕非凡的视力是其最大的优势之一。和许多其他鹰类一样，它看清细节的能力比人类要强四至八倍。这样它就能够看清两点五公里以外的一只小猴子，并能极精确地判定距离，若想快速抓获猎物，准确判断距离很明显是必需的。

It's hard to believe that a creature so well equipped to survive could- ever find itself underthreat. But with huge tracts of rainforest being felled in Centraland South America, the harpy'sfood sources are harder to find.

令人难以置信的是生存条件如此优越的生物竟然也会处于威胁之中，但随着中、南美洲大片热带雨林的被砍伐，大雕的食物来源更为困难。

The threat posed could soon be similar to that facing the harpy's near relative, the Philippinesmonkey-eating eagle. This acutely threatened bird was reduced in numbers to fewer than 100in the wild by the loss of its forest habitat and by the heavy demands of trophy hunters in thePhilippines.

不久，这种威胁就会和热带大雕的近亲——菲律宾食猴鹰所面临的威胁相似了。由于森林栖息地的丧失和菲律宾猎手的大量捕杀，这种受到严重威胁的鸟类的野外数量已减少到不足100只。

Like its Filipino cousm, the harpy eagle nests in the tops of the largest forest trees. It thereforeneeds an intact forest to breed. The seemingly invinable harpy is vulnerable for anotherreason. A mating pair is thought to produce only one eaglet every two years. Harpy eggs takeup to 60 days to hatch and chicks take a further 60 days before they learn to fly. What ismore, the youngster is fed by the parents for many months after it has learned to fly. Annualbreeding then is impossible.

和它的菲律宾同伴一样，热带大雕把巢筑在最大的树顶上。因此，它的繁殖需要一个保持完好的森林环境。似乎不可战胜的热带大雕易受伤害还有一个原因。据信，一对交配的大雕每两年才能生下一个雏雕。雕蛋的孵化需要60天，雏雕学飞之前还需60天。而且，雏雕学会飞行之后还需父母喂养多月。因而，大雕不可能每年繁殖。

Folklore has long held that the harpy eagle preys on human babies as well as forest animals. Tothe ancient Mayans of CentralAmerica the bird was Moan,a bird of ill omen and death. The harpyfrom which the eagle derives its name was a mythical wreaker of vengeance. Yet there is noevidence, according to British naturalist Leslie Brown, that children have ever been taken bythe harpy.

民间传说里，一直认为热带大雕既捕食森林动物，也捕食婴儿。对中美洲的古代玛雅人来说，热带大雕就是Moan，一种带来不祥和死亡的鸟。鹰的名字来自哈比( Harpy)，神话中的一个复仇者。然而，按照英国博物学家莱斯利·布朗的说法，还没有证据表明大雕曾经掠走过小孩。

But the Anglia Television Company fflm crew from England that compiled a televisiondocumentary titled Fury of the Forest can vouch for the harpy's ferociousness when its nest isthreatened. One camera team was attacked when filming a pair of harpys mating and nesting.

但制作电视纪录片《森林的愤怒》的英国英吉利电视公司的拍摄人员可以证明：热带大雕，在它的巢穴受到威胁时，是无比凶暴的。一个摄制组在拍摄一对大雕交配和筑巢时受到了它们的袭击。

The harpy eagle does not face the same immediate threat as its Filipino cousin. But if thedestruction of its forest habitat continues at its present rate, the largest of avian predators,too, could join those birds already on the endangered species list. Leslie Brown wrote in 1976that nearly half of the 59 species of eagle were under threat. Those who appreciate naturewill be hoping that the harpy can surmount this threat, to soar on over the forests of SouthAmerica.

我们只使用了大脑的百分之十吗?【第四篇】

Do We Only Use 10% Of Our Brains?

我们只使用了大脑的百分之十吗？

Have you ever heard that we humans use only ten percent of our brains? This oft-quoted myth holds a certain appeal because if it were true, then we could instantly become ten times more intelligent just by firing up that sleepy majority of the brain!

你是否曾经听说过我们人类只使用了大脑的百分之十？这个被经常引用的神话般的说法颇具吸引力，因为如果这种说法属实，那么我们只要激活沉睡的大部分大脑就可以比现在聪明十倍！

Animals Experiments

动物实验

The idea that we use only a small fraction of the brain dates back to animal experiments in the 19th century. When scientists stimulated a specific part of the brain, the animal moved its leg or tail. If a tiny part of the brain could do something so grand, what was the use of the rest of the brain? Some scientists assumed (rather unscientifically) that large parts of the brain were simply useless.

人类只使用了大脑很小一部分的观点可以追溯到19世纪的动物实验。当科学家刺激动物大脑的某个特殊部分时，动物的腿部或尾巴就会动弹。如果大脑这微小的一部分就可以引起这么大的动作，那么大脑其它部分有什么作用呢？一些科学家则假设(其实相当不科学)大脑的大部分没有任何作用。

Then, in the early 20th century, scientists observed that stimulating certain regions of the brain had no physical effects. They dubbed these seemingly useless parts of the brain the “silent cortex.” Today we know that in humans, much of the “silent cortex” is actually devoted to complex activities like language, learning, and imagining.

到了20世纪早期，科学家观察到，刺激动物大脑某个区域其身体没有任何反应。于是他们把这部分看起来无用的大脑称作“沉默的皮质”。如今我们都知道，在人类大脑中，许多“沉默的皮质”实际上在一些复杂活动诸如语言、学习和想象等方面发挥着重要的作用。

Brain Scans

脑部扫描

Brain scans have shown that different parts of the brain crackle into heightened activity as we shift our attention and focus, but even as we sleep, many areas of the brain are extremely active. Would you be smarter if your entire brain constantly worked to maximum capacity? Interestingly enough, the opposite is probably true. The less brain activity you need to perform a given task, the more the brain as a whole is capable of doing.

脑部扫描表明，当我们转移注意力或聚精会神时，大脑不同部位顿时提高活动强度，即使我们睡觉时，大脑的许多区域也极其活跃。如果整个大脑充分持续运转，人是否就会更聪明？有趣的是，结果恰恰相反。执行一项既定任务时脑部活动越少，大脑作为一个整体能做的事情就越多。
