萬萬沒想到！七個讓你驚呼“厲害了”的冷知識

Sitting too close to the TV won't harm your eyes more
坐得離電視太近更傷眼睛？多慮啦！

While watching a lot of TV can cause eye fatigue and potentially harm your vision, sitting too close doesn't make much of a difference, if any. However, this myth was true back before the 1950s, when companies made televisions that emitted dangerous levels of to 100,000 times more than what federal officials deemed safe.
雖然整天沉迷電視確實會導致眼疲勞並且可能損傷你的視力，但坐得離電視近一點並不會對眼睛危害更大。但是，這個在江湖上的傳說在20世紀50年代之前的確是真的，因爲當時生產的電視機會放射出大量危險級別的輻射——遠比美國聯邦官員們所聲稱的安全放射量高出10萬倍。

There's no such thing as an alpha wolf
頭狼？？不存在的~

A wildlife biologist by the name of L. David Mech published a book based on his observations of wolves in the wild. In it, he mentioned that he noticed "alpha wolves" leading small packs, and the popularity of the book made that term a common one. However, what Mech observed was actually just wolf parents and their grown cubs, so the concept of an "alpha wolf" as we know it is almost entirely wrong. Mech has tried to take his book out of print, and even wrote a paper correcting it.
野生動物學家L. David Mech曾經在觀察野狼的基礎上出過一本書。在書中，他提到每一支狼小隊都由一兩隻“頭狼”引導着。這一說法隨着這本書的大賣而火了。但事實上，Mech觀察到的只是帶着它們的幼崽的狼父母而已，所以我們所知道的“頭狼”的概念幾乎是完全不存在的。意識到了自己誤導後的Mech曾試圖停止翻印書籍，甚至寫了一篇論文來進行糾錯。

Doing sit-ups doesn't burn stomach fat
幫你減掉肚子上的贅肉？仰臥起坐：“臣妾做不到啊！”

Many people think that stomach exercises will help burn off stomach fat, but all it does is strengthen your abdominal muscles. In order to burn off fat, you have to do some form of exercise and healthy eating. And no, there's no way to specifically target belly fat before other areas of your body.
許多人以爲腰腹鍛鍊可以燃燒掉肚子上的脂肪，實際上，它們只是鍛鍊了你的腹肌而已。如果想要減脂的話，你得將鍛鍊和健康飲食搭配着來。而且，並沒有辦法讓你肚子上的脂肪比你身體其他部位的先減掉哦！

The forbidden fruit in the story of Adam and Eve in the Bible is never mentioned to be an apple
誰說亞當和夏娃偷吃的禁果是蘋果了？《聖經》不背這口鍋！

The book of Genesis mentions that the fruit came from a tree, but it doesn't say what kind of fruit, or what kind of tree. Apples started being associated with the story around the 12th century, possibly because of a Latin pun wherein the word "malus" means both "apple" and "evil."
《創世紀》中提到這個水果是從一棵樹上採下來的，但從來沒有說過這是一個什麼果、什麼樹。蘋果是12世紀左右才摻和進來的，可能是因爲在一個拉丁文雙關語裏面，"malus"同時具有“蘋果”和“邪惡”的意思吧！

（提到蘋果，貌似砸中牛頓的那隻蘋果也有待繼續考證哦）

Lemmings don't run off cliffs
愚蠢的人類想多了，旅鼠並不會成羣結隊跳下懸崖

你們小時候有沒有這樣一個神祕而有着悲壯色彩的故事？旅鼠的種羣數量一旦大於某個臨界值，其中的一部分就會像受到了某種召喚一樣，自動集結起來浩浩蕩蕩地開始一次大遷徙，直到來到一處懸崖邊統統跳下去被團滅！

The myth about lemmings committing suicide by running off cliffs came about from the 1950s nature documentary White Wilderness, produced by Disney. The filmmakers faked the scene in question (and allegedly actually threw lemmings off a cliff) in order to make it seem like they were willfully committing suicide.
關於旅鼠自殺的神祕傳說來源於20世紀50年代迪士尼拍攝的一部自然紀錄片《白色曠野》。影片拍攝者們僞造了現場（據說他們確實把旅鼠扔下了懸崖）來讓畫面看起來像是旅鼠們自主結束了自己的生命。

Carrots aren't better for your eyesight than any other vegetable with beta carotene
胡蘿蔔有益於你的視力是因爲其中含有β-胡蘿蔔素，但它的效果並沒有比其他含有β-胡蘿蔔素的食物更好

If you listened to your mom, you would think that carrots give you superpowered vision or something. The truth is that carrots contain beta carotene, which helps your body produce vitamin A, which does nourish your eyes. But there are plenty of other foods (such as sweet potatoes or goat liver) that also contain beta carotene, and vitamin A only helps keep your eyes healthy, not make them superhuman.
如果你聽媽媽的話，你或許會覺得吃胡蘿蔔會帶給你如鷹眼般的超能力。事實是，胡蘿蔔含有能幫助你的身體更好地吸收維他命A的β-胡蘿蔔素，它們確實滋養了你的眼睛。但是除此之外還有許多食物都含有β-胡蘿蔔素（比如甘薯，和羊肝），而且維他命A只會讓你的眼睛更健康，而不是真的就讓你變成鷹眼。

The Great Wall of China is not the only man-made object visible from space; in fact, it's barely visible at all
從外太空望向地球，長城並不是唯一能夠看見的人造建築。事實上，它壓根兒就看不見啊！

If you're in a very low orbit and you use some kind of scope or zoom in with a camera, then sure, you can probably just barely make out the Great Wall from space. But you could also see the Great Pyramid or a bunch of other large structures, seeing any of them from a higher orbit with the naked eye is probably impossible.
假如你飛在一個比較低的軌道上，裝備某種望遠鏡或者用相機放大，那麼你確實可能勉模模糊糊地從外太空分辨出長城。但是與此同時，你也能看見埃及金字塔和一幫其它的大型建築……當你飛到更高的軌道上之後，這些東西就在裸眼視界裏完全消失了。
