[05:42.69]为什么我们走路会转圈
[05:44.82]"Pin the Tail on the Donkey"
[05:46.74]"给驴安尾"
[05:48.66]is always funwhen you're watchlng rather than pinning.
[05:51.24]的游戏就永远乐趣无穷.如果你只是旁观者而不是游戏者,
[05:53.83]It is somewhat'surprising to see how the blindfolded7 performers act.
[05:56.91]观看那些蒙着眼的游戏者的表现有点让人惊奇.
[05:59.99]Instead of going straight,they always wander off to one side or the other
[06:03.38]他们总是歪向这边或那边,而不是一直向前走.
[06:06.76]The greater the distance to the donkey, the farther they go astray.
[06:10.00]距离驴子越远,他们偏得越厉害.
[06:13.24]Have you ever wondered why they are unable to walk straight ahead?
[06:16.06]你是否会问为什么他们不能走直线行走呢?
[06:18.88]It is a well-known fact that a person will move in a circle
[06:21.41]这是一个众所周知的事实,
[06:23.95]when he cannot use his eyes to control his direction.
[06:26.43]即当一上人不能用眼睛控制他的方向时,他会绕圈走.
[06:28.91]Dark nights, dense8 fogs, blinding snowstorms,
[06:32.03]黑夜,浓雾,让人盲目的暴风雪天气
[06:35.15]thick forests all these can keep a traveler from seeing where he is going
[06:38.58]以及茂密的森林－－所有这些都使旅行者看不清自己的去向．
[06:42.00]Then he is unable to move in any fixed9 direction, but walks in circles.
[06:45.83]于是他就不能沿着某一固定的方向行走，而是绕田圈子．
[06:49.65]Animals act the same way.
[06:51.53]动物也是如此．
[06:53.41]You have probably heard the saying
[06:55.61]你可能听说过一句谚语：
[06:57.80]"running around like a chicken with its head cut off."
[07:00.32]＂像被砍掉头的鸡一样绕圈．＂
[07:02.84]Well, a chicken with its head cut off actually does run around in circles.
[07:05.78]真的，头被砍掉的鸡还真昌绕着圈子跑．
[07:08.72]Blind birds fly in circles.
[07:10.99]眼瞎的鸟儿也是绕圈子飞．
[07:13.27]And a blindfolded dog will swim in circles.
[07:16.05]还有，被蒙胧住眼睛的狗游泳时也绕着圈游．
[07:18.83]A Norwegian biologist, F.O. Guldbergdecided
[07:21.91]一位挪威生物学家古尔伯格
[07:25.00]that this problem of circular movementwas worth investigating.
[07:28.26]认为这种转圈运动问题值得研究．
[07:31.53]He collected many true stories on the subject.
[07:34.16]就此课题了收集了许多真实的故事．
[07:36.80]One of his stories is about people rowing on a lake
[07:39.44]其中一个故事是讲在一个有雾的黑漆漆的夜里，
[07:42.08]during a fog on a dark night.
[07:44.05]一群人在湖上划船．
[07:46.02]One group of rowers who tried to cross three miles of water
[07:49.05]这群划船的人想穿过3英里的水面
[07:52.08]in foggy weathernever succeeded in reaching their goal. [07:54.62]却怎么也达不到他们的目标.
[07:57.15]Without knowing it,they rowed in two large circles.
[08:00.48]他们不知不觉地划了两个大圆圈.
[08:03.81]When they finally got to the shore,
[08:06.14]当他们终于靠岸时,
[08:08.46]they discovered that they were at the spot they had started from.
[08:11.19]发现又回到了出发的地方.
[08:13.92]After studying many stories such as this,
[08:16.74]研究了许多这样的故事以后,
[08:19.57]Professor Guldberg wrote an article in which he discussed
[08:22.54]古尔伯格教授撰文讨论了
[08:25.52]Circular Motion as the Basic Motion of Animals.
[08:28.30]"转圈运动是动物的基本运动方式".
[08:31.09]"A simple example will help you to understand his explanation ofwhy we walk in circles.
[08:35.02]一个简单的例子可以帮助你理解他对为什么我们走路会转圈这个问题做的解释.
[08:38.95]Have you ever wound up a toy automobile10 and started it off across the floor?
[08:42.42]你曾经给一辆玩具汽车上满发条并让它们地板上跑过吗?
[08:45.90]Then you know that it will rarely travel in a straight path.
[08:48.47]那么你就知道它很少能沿一条直线运动.
[08:51.04]It will travel, instead, in some kind of are, or curve.
[08:54.02]相反,它会跑成一条弧线或一条曲线[08:57.00]If it is to travel in a straight llne,
[08:59.02]如果让它跑成直线,
[09:01.05]the wheels on both sideshave to be of exactly equal size.
[09:04.22]两边的轮子就要完全一样大小.
[09:07.40]If they are not,
[09:09.07]如果不是,
[09:10.74]the little automobile turns toward the sidewith the smaller wheels.
[09:13.86]小玩具汽车就会向较小的轮子那边转.
[09:16.98]Circular, movement in walking is caused in much the same way.
[09:20.16]行走时的转圈现象 也是由十分相同的原因引起的.
[09:23.33]Us-ally a manwalking will "watch his step" and "look where he is going."
[09:27.25]通常一个人走路时会"注意脚下"并"看清方向".
[09:31.17]He needs his senses' especially his eyesto get to the point he intends to reach.
[09:35.14]他需要运用他的感觉,特别是眼睛,以到达自己要去的地方.
[09:39.11]When he cannot use his eyes to guide his steps,
[09:41.77]当他不能用眼睛引导脚步时,
[09:44.44]he will walk straight only if he takes a stepof the same length with each foot.
[09:47.47]只有两脚迈出的步伐完全一样他才能走得笔直.
[09:50.50]In most people,however,muscle development is not the same in both legs
[09:54.18]然而对于多数人来说,两腿的肌肉发达程度并不一样,
[09:57.86]so that it is probable that the steps will be uneven11.
[10:00.44]所以走起步来很可能不匀称.
[10:03.01]The difference may be so small that no one is aware of it.
[10:05.69]这种差异也许很小以至于没有人会注意到它.
[10:08.37]But small as his, it can cause circular movement.
[10:11.25]但是虽然差异很小,它却能千百万边境转圈移动.
[10:14.14]Let us suppose that a man's left foot takes a step 20 inches long
[10:17.67]假设一个人左脚每步走20英寸
[10:21.19]and that his right foot takes a step 30 inches long.
[10:24.08]而右脚每步走30英寸.
[10:26.96]Now suppose he takes ten step
[10:29.34]现在假设他走了10步
[10:31.72]--five with his left footand five with his right.
[10:34.40]----左脚5步右脚5步.
[10:37.07]His left foot will travel 100 inches.
[10:39.56]其左脚将走100英寸.
[10:42.04]His right foot will travel 150 inches.
[10:44.82]其右脚则走了150英寸.
[10:47.60]This sounds impossible. One foot cannot remain 50 inches behind the other
[10:51.53]这听起来不太可能.一只脚不可能落后于另一只脚50英寸.
[10:55.46]What really happens?At each step the man turns a little bit to the left.
[10:59.29]事实会怎样呢?每走一步,这个人就往左偏一点.
[11:03.12]Sooner or later he makes a complete circle
[11:05.69]迟早他就会走完整的一圈.
[11:08.26]The tracks of his feet, however, make two circles, one inside the other
[11:12.00]他的足迹,就这样,形成内外两个圈.
[11:15.74]His left foot makes the smaller circle because it is taking smaller steps
[11:19.00]他的左脚走了内圈,因为左脚步伐较小.
[11:22.27]His right foot makes the larger circle because it is taking larger steps
[11:25.83]他的右脚走了外圈,因为右脚步伐较大.
[11:29.40]This is why a person may walk in an are when he sets out in a straight line.
[11:32.88]这就是一个人往前走直线却反而走出弧线来的原因.
[11:36.37]The muscles of a man's arms are no more identical than the muscles of his legs [11:40.09]一个人手臂的肌肉和他的两腿的肌肉一样不是完全相同的.
[11:43.82]This explains why the rowers who set out to cross the lakeat night rowed in a circle.
[11:47.70]这就解释了为什么划船的人在夜间想划过湖面反而却划成圆圈.
[11:51.58]By the same rule, a bird's wings do not develop evenly
[11:54.81]同样的规则 ,鸟儿的翅膀也发育不均衡,
[11:58.05]and so it will fly in circles when blinded.
[12:00.48]于是当蒙住鸟儿的眼睛时,它就会转圈飞.
[12:02.91]Thus,dear readers,our circular mystery has a very straight answer.
[12:06.39]因此,亲爱的读者,我们的圆圈奥秘却有着一个非常直截了当的答案.
[00:08.22]友善和礼貌的重要性
[00:11.34]"Frankly, I think you're boring."
[00:13.86]"老实说,我觉得你很乏味."
[00:16.38]Why do we seldom hear people speak so honestly?
[00:19.50]为什么我们很少听到人们说话如此坦城?
[00:22.62]Unless you want to end a relationship,
[00:25.00]除非你想结束与他或她的关系,
[00:27.38]you don't tell another person what you think of her or him like this.
[00:30.80]你当然不会像这样告诉他或她你的真实想法.
[00:34.22]Failing to be impressed by a friend's collection of stamps,
[00:37.55]如果一个朋友向你展示他的集邮册,你丝毫未被打动;
[00:40.88]yawning when a golfer tells you about that great shot he made on the 14th hole,
[00:44.85]如果一个高尔球手告诉你他在打第十四洞时打了如何漂亮的一杆,而你却打了个哈欠;

[06:10.00]距离驴子越远,他们偏得越厉害.
[06:13.24]Have you ever wondered why they are unable to walk straight ahead?
[06:16.06]你是否会问为什么他们不能走直线行走呢?
[06:18.88]It is a well-known fact that a person will move in a circle
[06:21.41]这是一个众所周知的事实,
[06:23.95]when he cannot use his eyes to control his direction.
[06:26.43]即当一上人不能用眼睛控制他的方向时,他会绕圈走.
[06:28.91]Dark nights, dense8 fogs, blinding snowstorms,
[06:32.03]黑夜,浓雾,让人盲目的暴风雪天气
[06:35.15]thick forests all these can keep a traveler from seeing where he is going
[06:38.58]以及茂密的森林－－所有这些都使旅行者看不清自己的去向．
[06:42.00]Then he is unable to move in any fixed9 direction, but walks in circles.
[06:45.83]于是他就不能沿着某一固定的方向行走，而是绕田圈子．
[06:49.65]Animals act the same way.
[06:51.53]动物也是如此．
[06:53.41]You have probably heard the saying
[06:55.61]你可能听说过一句谚语：
[06:57.80]"running around like a chicken with its head cut off."
[07:00.32]＂像被砍掉头的鸡一样绕圈．＂
[07:02.84]Well, a chicken with its head cut off actually does run around in circles.
[07:05.78]真的，头被砍掉的鸡还真昌绕着圈子跑．
[07:08.72]Blind birds fly in circles.
[07:10.99]眼瞎的鸟儿也是绕圈子飞．
[07:13.27]And a blindfolded dog will swim in circles.
[07:16.05]还有，被蒙胧住眼睛的狗游泳时也绕着圈游．
[07:18.83]A Norwegian biologist, F.O. Guldbergdecided
[07:21.91]一位挪威生物学家古尔伯格
[07:25.00]that this problem of circular movementwas worth investigating.
[07:28.26]认为这种转圈运动问题值得研究．
[07:31.53]He collected many true stories on the subject.
[07:34.16]就此课题了收集了许多真实的故事．
[07:36.80]One of his stories is about people rowing on a lake
[07:39.44]其中一个故事是讲在一个有雾的黑漆漆的夜里，
[07:42.08]during a fog on a dark night.
[07:44.05]一群人在湖上划船．
[07:46.02]One group of rowers who tried to cross three miles of water
[07:49.05]这群划船的人想穿过3英里的水面
[07:52.08]in foggy weathernever succeeded in reaching their goal. [07:54.62]却怎么也达不到他们的目标.
[07:57.15]Without knowing it,they rowed in two large circles.
[08:00.48]他们不知不觉地划了两个大圆圈.
[08:03.81]When they finally got to the shore,
[08:06.14]当他们终于靠岸时,
[08:08.46]they discovered that they were at the spot they had started from.
[08:11.19]发现又回到了出发的地方.
[08:13.92]After studying many stories such as this,
[08:16.74]研究了许多这样的故事以后,
[08:19.57]Professor Guldberg wrote an article in which he discussed
[08:22.54]古尔伯格教授撰文讨论了
[08:25.52]Circular Motion as the Basic Motion of Animals.
[08:28.30]"转圈运动是动物的基本运动方式".
[08:31.09]"A simple example will help you to understand his explanation ofwhy we walk in circles.
[08:35.02]一个简单的例子可以帮助你理解他对为什么我们走路会转圈这个问题做的解释.
[08:38.95]Have you ever wound up a toy automobile10 and started it off across the floor?
[08:42.42]你曾经给一辆玩具汽车上满发条并让它们地板上跑过吗?
[08:45.90]Then you know that it will rarely travel in a straight path.
[08:48.47]那么你就知道它很少能沿一条直线运动.
[08:51.04]It will travel, instead, in some kind of are, or curve.
[08:54.02]相反,它会跑成一条弧线或一条曲线[08:57.00]If it is to travel in a straight llne,
[08:59.02]如果让它跑成直线,
[09:01.05]the wheels on both sideshave to be of exactly equal size.
[09:04.22]两边的轮子就要完全一样大小.
[09:07.40]If they are not,
[09:09.07]如果不是,
[09:10.74]the little automobile turns toward the sidewith the smaller wheels.
[09:13.86]小玩具汽车就会向较小的轮子那边转.
[09:16.98]Circular, movement in walking is caused in much the same way.
[09:20.16]行走时的转圈现象 也是由十分相同的原因引起的.
[09:23.33]Us-ally a manwalking will "watch his step" and "look where he is going."
[09:27.25]通常一个人走路时会"注意脚下"并"看清方向".
[09:31.17]He needs his senses' especially his eyesto get to the point he intends to reach.
[09:35.14]他需要运用他的感觉,特别是眼睛,以到达自己要去的地方.
[09:39.11]When he cannot use his eyes to guide his steps,
[09:41.77]当他不能用眼睛引导脚步时,
[09:44.44]he will walk straight only if he takes a stepof the same length with each foot.
[09:47.47]只有两脚迈出的步伐完全一样他才能走得笔直.
[09:50.50]In most people,however,muscle development is not the same in both legs
[09:54.18]然而对于多数人来说,两腿的肌肉发达程度并不一样,
[09:57.86]so that it is probable that the steps will be uneven11.
[10:00.44]所以走起步来很可能不匀称.
[10:03.01]The difference may be so small that no one is aware of it.
[10:05.69]这种差异也许很小以至于没有人会注意到它.
[10:08.37]But small as his, it can cause circular movement.
[10:11.25]但是虽然差异很小,它却能千百万边境转圈移动.
[10:14.14]Let us suppose that a man's left foot takes a step 20 inches long
[10:17.67]假设一个人左脚每步走20英寸
[10:21.19]and that his right foot takes a step 30 inches long.
[10:24.08]而右脚每步走30英寸.
[10:26.96]Now suppose he takes ten step
[10:29.34]现在假设他走了10步
[10:31.72]--five with his left footand five with his right.
[10:34.40]----左脚5步右脚5步.
[10:37.07]His left foot will travel 100 inches.
[10:39.56]其左脚将走100英寸.
[10:42.04]His right foot will travel 150 inches.
[10:44.82]其右脚则走了150英寸.
[10:47.60]This sounds impossible. One foot cannot remain 50 inches behind the other
[10:51.53]这听起来不太可能.一只脚不可能落后于另一只脚50英寸.
[10:55.46]What really happens?At each step the man turns a little bit to the left.
[10:59.29]事实会怎样呢?每走一步,这个人就往左偏一点.
[11:03.12]Sooner or later he makes a complete circle
[11:05.69]迟早他就会走完整的一圈.
[11:08.26]The tracks of his feet, however, make two circles, one inside the other
[11:12.00]他的足迹,就这样,形成内外两个圈.
[11:15.74]His left foot makes the smaller circle because it is taking smaller steps
[11:19.00]他的左脚走了内圈,因为左脚步伐较小.
[11:22.27]His right foot makes the larger circle because it is taking larger steps
[11:25.83]他的右脚走了外圈,因为右脚步伐较大.
[11:29.40]This is why a person may walk in an are when he sets out in a straight line.
[11:32.88]这就是一个人往前走直线却反而走出弧线来的原因.
[11:36.37]The muscles of a man's arms are no more identical than the muscles of his legs [11:40.09]一个人手臂的肌肉和他的两腿的肌肉一样不是完全相同的.
[11:43.82]This explains why the rowers who set out to cross the lakeat night rowed in a circle.
[11:47.70]这就解释了为什么划船的人在夜间想划过湖面反而却划成圆圈.
[11:51.58]By the same rule, a bird's wings do not develop evenly
[11:54.81]同样的规则 ,鸟儿的翅膀也发育不均衡,
[11:58.05]and so it will fly in circles when blinded.
[12:00.48]于是当蒙住鸟儿的眼睛时,它就会转圈飞.
[12:02.91]Thus,dear readers,our circular mystery has a very straight answer.
[12:06.39]因此,亲爱的读者,我们的圆圈奥秘却有着一个非常直截了当的答案.
