【编者按】很多不为人注意的细微地方也是有它的道理的啊。

Why do pigeons wobble their head while walking?【译】鸽子走路时为什么摇头晃脑？【单词】pigeons 原型：pigeon ['pij-uh n]['pɪdʒɪn] n. 鸽子【单词】wobble ['wob-uhl]['wɒbl] vt. 使摇晃；使动摇，摆动，摇动

It's because they have comparatively limited vision (their eyes being on the sides of their head).【译】这是因为他们的视力相对有限（他们的眼睛在头的两侧）。【单词】comparatively [kuhm-'par-uh-tiv][kəm'pærətɪvli] adv. 比较地；相对地【单词】limited 原型：limit ['lim-it]['lɪmɪt] vt. 限制；限定【单词】vision ['vizh-uhn]['vɪʒn] n. 视力；视觉；眼光；洞察力

They bob their head to focus on different parts of the world around them to build up a complete view.【译】它们摇头晃脑地盯着周围世界的不同地方，以建立一个完整的视野。【短语】focus on... 专注于...，集中在...上；例句：We focus on your lifestyle, to ignite your senses. 我们关注你的生活方式，点燃你的感觉。【单词】bob [bob][bɒb] v. 上下疾动；上下快速摆动【单词】build [bild][bɪld] v. 建造；创建；逐渐增强

We do the same thing, except we move the eyeball (saccades).【译】我们（人类也会）做同样的事情，只是我们移动眼球（扫视）。【单词】except [ik-'sept][ɪk'sept] conj. 除非；除了 ... 之外；若不是【单词】eyeball ['ahy-bawl]['aɪbɔːl] n. 眼球；眼珠【单词】saccades [sa-'kahd, suh-]['sækɑːdz] 跳阅, 扫视

Pigeons mainly bob their heads when walking to stabilize their vision and gain depth perception.【译】鸽子走路时摇头，主要是为了以稳定视力和获得深度知觉。【单词】mainly ['meyn-lee]['meɪnli] adv. 主要地；大部分地【单词】stabilize ['stey-buh-lahyz]['steɪbəlaɪz] v. 使安定；使坚固【单词】gain [geyn][ɡeɪn] v. 获得；到达；增加；获利【单词】depth [depth][depθ] n. 深度；深刻；深奥；深；厚度【单词】perception [per-'sep-shuhn][pə'sepʃn] n. 观念；洞察力；认识能力

Chickens and other birds do this too, because they have their eyes on the sides of their heads and don't have very good depth perception.【译】鸡和其他鸟类也这样做，因为它们的眼睛长在头的两侧，没有很好的深度感知能力。【单词】Chickens 原型：chicken ['chik-uh n]['tʃɪkɪn] n. 鸡【单词】birds 原型：bird [burd][bɜːd] n. 鸟；禽

Interestingly, their head doesn't actually move back and forth, but instead they move their head forward and then keep it still while their body catches up.【译】有趣的是，它们的头实际上并不是前后移动，而是向前移动头部，然后在身体跟上时保持不动。【单词】Interestingly 原型：interestingly 副词 adv. 有趣地【单词】forth [fawrth, fohrth][fɔːθ] adv. 向前；向外；露出【单词】catches 原型：catch [kach][kætʃ] v. 赶上；抓住

This happens over and over again which creates the illusion that they are bobbing their head back and forth, when in reality they are only moving it forward and then holding it in place while their body catches up.【译】这种情况一次又一次地发生，这就造成了一种错觉，即他们在来回摆动脑袋，而实际上他们只是在向前移动，然后在身体跟上的时候保持住头部位置。【短语】in place 表示“在合适的位置”。如：Have you got all the lights in place yet?【单词】happens 原型：happen ['hap-uhn]['hæpən] vi. 发生；碰巧；出现；偶遇【单词】creates 原型：create [kree-'eyt][kri'eɪt] v. 创造；造成【单词】illusion [ih-'loo-zhuhn][ɪ'luːʒn] n. 错觉；幻觉【单词】reality [ree-'al-i-tee][ri'æləti] n. 真实；现实；实际

Birds' eyes, unlike those of humans, are (usually) fixed in one direction - they can't look in different directions without moving their heads.【译】与人类的眼睛不同，鸟类的眼睛（通常）是固定在一个方向上的——它们不动头就不能朝不同的方向看。【单词】unlike [uhn-'lahyk][ˌʌn'laɪk] prep. 不像，与…不同；与 ... 平时不同【单词】fixed 原型：fix [fiks][fɪks] v. 使 ... 固定；确定【单词】direction [dih-'rek-shuh n, 'dahy-][də'rekʃn] n. 方向；趋势

Notice, in humans, that our eyes jump around when focusing on new objects, instead of traveling in a smooth line.【译】注意，对人类来说，当我们聚焦于新的物体时，我们的眼睛会跳来跳去，而不是沿着一条平滑的直线移动。【短语】instead of 代替（……的是）；而不是…；例句：Instead of pressing forward, they drew back. 他们不仅没有前进，反而后退了。Oops! I put in sugar instead of salt. 啊！我错把糖当盐放了。【单词】Notice 原型：notice ['noh-tis]['nəʊtɪs] vt. 注意；留心；通知【单词】jump [juhmp][dʒʌmp] v. 跳跃；跳动；跳越【单词】objects 原型：object ['ob-jikt, -jekt]['ɒbdʒɪkt] n. 物体；目标；对象【单词】traveling 原型 travel ['trav-uh l]['trævl] v. 移动，旅游，旅行【单词】smooth [smooth][smuːð] adj. 光滑的；平稳的；流畅的；均匀的
