誰(shuí)跑得更快？他OR它？

The fastest cheetah on Earth has done it again, breaking her previous world record for the 100-meter dash and setting a new best time of 5.95 seconds.

地球上奔跑速度最快的動(dòng)物——獵豹又一次打破了之前的100米奔跑記錄，重新書(shū)寫(xiě)了5.95秒的世界紀(jì)錄。

This feat surpasses the fastest of all human 100-meter sprinters by almost four seconds. Usain Bolt, a Jamaican sprinter now competing at the 2012 London Olympics, holds the human world record at 9.58 seconds in the 100-meter dash.

5.95秒的速度比人類最快的100米奔跑速度要快近4秒。牙買(mǎi)加短跑明星博爾特現(xiàn)在正在參加2012年倫敦奧運(yùn)會(huì)并創(chuàng)造了100米短跑世界紀(jì)錄——9.58秒。

Cheetahs, of course, are built to run faster than humans, regularly clocking speeds of up to around 60 miles per hour (96.5 kilometers per hour). During a photo shoot with National Geographic Magazine, a cheetah from the Cincinnati Zoo named Sarah covered 100 meters at 61 mph (98 kph).

當(dāng)然，獵豹天生就比人類的奔跑速度快，獵豹的奔跑速度大約為60 英里每小時(shí)(96.5千米每小時(shí))。在國(guó)家地理雜志上的一張照片中，一只來(lái)自辛辛那提動(dòng)物園名叫薩拉的獵豹，其奔跑速度達(dá)到98千米每小時(shí)。

The sprint broke Sarah's previous world record, set in 2009 when she ran the same distance in 6.13 seconds. That sprint broke the previous record set in 2001, when a male South African cheetah named Nyana ran 100 meters in 6.19 seconds.

薩拉這次的成績(jī)打破了她之前在2009年創(chuàng)下的6.13秒的世界紀(jì)錄。而2009年她以6.13秒的成績(jī)打敗了另一只名叫娜娜的南非豹，其100米奔跑速度為6.19秒。

Sarah is 11 years old and is part of the zoo's Cat Ambassador Program. Her sprint was documented with funding from the National Geographic's cat conservation effort the Big Cats Initiative.

11歲的薩拉參加了動(dòng)物園貓科動(dòng)物大使項(xiàng)目。她參加的100米短跑活動(dòng)獲得了國(guó)家地理貓科動(dòng)物保護(hù)機(jī)構(gòu)的基金支持，且其成績(jī)會(huì)被記錄在案。

The record-breaking run took place on a course designed by the Road Running Technical Council of USA Track & Field. Sarah chased a fluffy toy lure around the course, breaking the record on her very first run.

這次100米賽道由美國(guó)田徑運(yùn)行技術(shù)委員會(huì)設(shè)計(jì)。薩拉是在追逐賽道上的一個(gè)毛絨誘餌，第一次參加該項(xiàng)目的薩拉便打破了記錄。

The secret to cheetah speed is in its long, flexible spine, which allows the animal to cover up to 22 feet (6.7 meters) on every stride. Cheetahs also vary their strides per second as they speed up, taking more strides per second as they run faster. That seems to be a special talent, researchers reported in June in the Journal of Experimental Biology. Other speedy creatures such as greyhounds keep a steady number of strides per second no matter how fast they run.

獵豹之所以能夠達(dá)到如此快的奔跑速度得益于它那又長(zhǎng)又靈活的脊椎，這使得它可每次可以跨越6.7米的距離。獵豹加速時(shí)每秒還可以調(diào)整其跨越次數(shù)，跑得越快，每秒的跨越次數(shù)就越多。這似乎是一種特殊的天賦。而其他快速奔跑的動(dòng)物如灰狗在奔跑時(shí)，無(wú)論跑多快，它均保持著穩(wěn)定數(shù)量的跨越次數(shù)。

Cheetahs' sharp claws also act like cleats when they run, giving the big cats traction.

Cheetahs are endangered in the wild, with an estimated 9,000 to 12,000 living outside of zoos today.

野生獵豹正在瀕臨滅絕，現(xiàn)存數(shù)量?jī)H為9000到12000只。
