　　生活中有些常识和传闻其实是错误的，比如地球围绕太阳转，鲨鱼不会得癌症等等。让我们一起修正这些错误的常识吧!

　　The Earth isn't actually orbiting around the Sun. It's orbiting around the Solar System's center of mass known as the Barycenter. Although this point often falls within the mass of the Sun, it can be shifted by the pull of larger planets. Therefore, at least some of the time, everything in the solar system is orbiting around empty space.

　　事实上，地球并非围着太阳转。它绕着太阳系的质心转动。尽管这个质心通常位于太阳内，但由于大行星的引力，它的位置可能会移动。因此至少某些时候，太阳系的所有物体是绕着空空如也的某片宇宙转动的。

　　Tomato

　　While the Supreme Court did rule that tomatoes are vegetables in the legal sense for the purpose of taxation, they did not claim they are vegetables in any botanical sense. They are still fruits.

　　尽管最高法院规定西红柿在征税时算蔬菜，但这并不意味着从植物学角度说，西红柿是蔬菜。它们还是水果。

变色龙

　　Chameleon

　　Chameleons don't change their color to blend in to their surroundings. They change their color to communicate.

　　变色龙变色不是为了隐身，而是为了和同类交流。

　　Bat

　　No bat is blind. While many species do use echolocation, some have excellent night vision and don't rely on echolocation at all.

　　蝙蝠不是瞎子。很多种蝙蝠使用回声定位。但也有一些蝙蝠拥有优秀的夜视能力，它们根本不靠回声定位。

香蕉树

　　Banana

　　香蕉树不是树，是草本植物。

　　Goldfish

　　Goldfish don't have a 7 second memory. It's actually much better than that.

　　金鱼的记忆不止7秒。

　　Shark

　　Sharks actually do get cancer.

　　鲨鱼会得癌症。

　　Dog

　　Dogs don't sweat through their tongue. Most of their sweat glands are located in their foot pads. While panting does keep them cool, panting is not equivalent to sweating.

　　狗不是通过舌头排汗。它们大部分的汗腺长在脚底的软垫上。喘气确实能让它们保持凉爽，但这和流汗是两回事。

　　Napoleon

　　Napoleon was actually taller than the average Frenchman.

　　事实上，拿破仑比同时代法国人的平均身高要高。
