The Dirt on Bottled Water
不环保的瓶装水
（图片出自摄图网）
Bottled water seems like a harmless and convenient product of today's world. However, the truth is that the results of bottling water aren't all good.
Bottled water advertisements have people convinced that bottled water is healthier than tap water. However, in most cases, it isn't. Bottled water is stored for long periods of time at warm temperatures. As bottles age, the chemical used to make plastic flexible gets into the water. Microorganisms can also grow in this environment at high rates. Health officials are particularly concerned about how these effects influence children, the elderly, and other vulnerable individuals. In fact, they say that infants in particular should never be given bottled water unless it is boiled first.
Furthermore, some bottled water companies actually use the same tap water or well water that is available to the general public. A few companies have even been found using water sources dangerously close to toxic sites. Environmentalists have even more concerns. Millions of barrels of oil are used in the production, transportation, and storage of bottled water. This places a strain on limited natural resources and creates vast amounts of greenhouse gases. Additionally, a single plastic bottle can take over 1,000 years to break down.
Before you buy your next bottle of water, remember that the process that produces it is often expensive, unhealthy, and bad for the environment. Then, ask yourself if that's something you really want to buy.
瓶装水看起来似乎无害，也是现今世界方便的产物。然而事实是，瓶装水造成的结果并不是那么正面。
瓶装水的广告让人们相信瓶装水比自来水健康。然而，在大多数的情况下却并非如此。瓶装水长时间存放在高温下。随着瓶子老化，用来使塑料瓶有弹性的化学物质会溶入水中。微生物在这样的环境下会快速滋长。卫生官员特别关注这对小孩、老人及其他弱势人群的影响。事实上，他们说尤其不该让婴儿喝瓶装水，除非是先煮开。
更有甚者，某些瓶装水公司实际上就是使用大众可取得的自来水或井水。有些公司还被发现使用的水源非常靠近有毒地区。环保人士则更忧心忡忡。瓶装水的制造、运送和储藏过程更是耗尽数百万桶石油。这让有限的自然资源更加吃紧，而且还会产生大量的温室气体。此外，一个塑料瓶可能要花上一千年才能分解。
下次你买瓶装水之前，要记得其制造过程既昂贵又不健康，而且不环保。然后问问你自己，这真是你要买的东西吗？
Sneezing in the Sun
光性喷嚏反射症候群
（图片出自摄图网）
When going outside, we expect our eyes to have to adjust to the sunlight. But would you be surprised if someone told you the light also made them sneeze? For people who don't experience this unusual effect, it might sound crazy. However, it's a real phenomenon called the photic sneeze reflex.
The ancient Greek philosopher Aristotle first wrote about the photic sneeze reflex over two thousand years ago, but scientists have not yet figured it out. The common explanation is that the nerves that control sneezing and the nerves for our eyes are located very close to one another. In some people, they might be so close that electrical signals from one can pass into the other. As many as 25 percent of all people have the condition.
People who experience the reflex sneeze a(n) average of two times when they see bright light after being in the dark for a while. When their eyes fully adjust to the light, the need to sneeze goes away. For most people, this reflex is just an annoyance. However, for others it can be extremely dangerous. For example, it's easy to imagine what might happen if a jet pilot suddenly sneezed after flying into the sunlight.
Though it still baffles scientists, there's no denying that the photic sneeze reflex is real. If you still think it's unbelievable, just ask a few of your friends. The odds are that one of them knows what it feels like to have a ray of sunlight tickle their nose.
当我们外出时，我们希望双眼能适应阳光。但如果有人跟你说光线会让他们打喷嚏，你会不会觉得很惊讶？对于没经历过这种不寻常效应的人来说，这听起来可能很疯狂。不过，这是真实的现象，称之为光性喷嚏反射。
古希腊哲学家亚里士多德在两千多年前首度写下关于光性喷嚏反射的现象，但科学家至今对这现象仍无法全部了解。一般的解释是控制喷嚏的神经和眼部神经的位置十分接近。在某些人身上，这两种神经可能因太过接近，以至于其中一组神经发出的电波会传到另一组。全球有多达四分之一的人口有这种症状。
有这类反射作用的人在暗处一段时间后，见到光时平均会打两次喷嚏。当他们的双眼完全适应光线后，想打喷嚏的情况就会停止。对大多数人来说，这种反射作用只是令人心烦。但对另一些人来说，这可能极度危险。举例来说，一名飞行员飞到阳光下时突然打喷嚏的话，其后果不难想象。
虽然科学家仍十分困惑，但不可否认地是，光性喷嚏反射确实存在。如果你还是觉得不可思议，不妨问问你的一些朋友，他们中的一些极有可能会知道被阳光搔弄鼻子是什么感觉。
