2017，它们从科幻走向了现实

贾宇帆

Less than a century ago， people were terrified by the appearance of the small TV set in stores. Many couldn&apos；t understand what was happening on the screen， while others even believed that there were little people living in those strange， new boxes. In the past decades， Hollywood movie producers and science-fiction writers let their imagination loose1）， coming up with bizarre2） concepts and ideas. Some of these science-fiction things actually exist in 2017， and to some， they might seem scary as the TV set was a long time ago.

Hoverboards3）

Every kid on the block wanted a hoverboard after Back to the Future was released. They look like a skateboard， but they are much cooler. Didn&apos；t you imagine what you could have done with one of these？ Well， they actually exist. Who knows when they&apos；ll become the next big worldwide trend？

2

Mosquito Drones4）

The drones haven&apos；t impressed you much？ Well， I want to tell that in the year 2017， we have mosquito drones. Yes， small drones that look like mosquitos. Don&apos；t worry！ They aren&apos；t meant to bite you—even though they could—they are mostly used to take pictures and follow movement.

Holographic5） Display

Holograms6） are one of the most sci-fi things anyone could have ever imagined， and the knowledge and technology needed for this seems far in the future. But just like 3D printers， gadgets7） that have holographic display are here and you can buy one yourself.

Cloud-based Data Storage

You might not be aware， but the way we store our data is pretty futuristic. No wires， no physical space， just a "cloud" where everything goes and can be transferred from one place to another. Even mobile devices have it， and these were pretty futuristic when your grandparents were young.

Doors That Clean Themselves

Cleaning takes time， and we would rather do something more productive and fun than doing house chores all day. But objects cleaning themselves seem like something taken from a science-fiction movie. Well， not anymore. Today there are door handles which sterilize8） alone.

Self-tying Shoes

Besides self-cleaning objects， wouldn&apos；t it be great to have self-tying shoes？ You might remember that those looked pretty cool in Back to the Future. Well， Nike released such a model in 2016. Buy a pair now if you want to feel like Marty.

懸浮滑板

在电影《回到未来》上映（编注：1985年）之后，大街上没有孩子不想要一个悬浮滑板。它们看起来像滑板，但是比滑板酷多了。难道你没想象过你原本可以用这样一个悬浮滑板做什么吗？好吧，它们确有其物！谁知道它们何时会成为下一个风靡全球的潮流呢？endprint

蚊子无人机

那些无人机没有给你留下深刻印象？好吧，我想說2017年我们有了蚊子无人机。是的，看起来像蚊子的小无人机。别担心！它们可不是用来咬你的——尽管它们可以——它们主要用于拍照和追踪动态。

3

全息显示

全息影像是每个人所能想到的最具科幻性的东西之一，其所需的知识和技术似乎还属于遥远的未来。但是就像3D打印机一样，拥有全息显示的小玩意儿眼下就有，你还可以给自己买一个。

4

云数据存储

你或许没有意识到，但我们存储数据的方式可是极具未来感的。没有电线，没有物理空间，只是一片“云”就能让所有数据都存在这里，并且可以从一个地方转存到另一个地方。甚至连移动设备都具有这一功能，而这些技术在你祖父母还年轻的时候可是极具未来感的。

5

自清洁的门

清洁需要时间，而且比起整天做家务，我们宁愿做更富有成效、更有趣的事情。可是，能够自清洁的物品似乎是科幻大片里才有的东西。不过，现在再也不是了。如今我们可是拥有能够自动消毒的门把手了。

6

自动系鞋带的鞋

除了可自动清洁的物品外，要是有自动系鞋带的鞋子岂不是也很好？你或许记得《回到未来》里那些看起来超酷的鞋子。嗯，耐克在2016年就发布了这样一款鞋子。如果你想体验马蒂（编注：《回到未来》男主人公）的感觉，现在就买一双吧。

7

探索外星球的机器人

阿诺德·施瓦辛格曾去过火星，至少在《宇宙威龙》里去过。那么，谁是第一个探索这颗星球的？是人类……在他们那些机器人朋友的帮助下。你可能没有注意到，“好奇”号火星车（编注：NASA于2011年发射到火星的探测器）如今已经在火星上有一段时间了，它还在探索着这颗星球并发现新的事物。是的，探索外星球的机器人这一科幻概念已经变成现实啦。

同时看多个频道

在你小的时候，你或许希望，可以的话能够同时看多个电视频道——或者至少不再和你的家人争论轮到谁选择频道了。这看起来像是一种属于遥远未来或者是你那科幻小说的想象中才有的技术。然而，现在卖得最多的电视就有这一功能，而且所有的有线电视公司都提供这一选择。

9

压缩食品

在本文列举的这些科幻奇迹中，压缩食品可能看起来只是一个稀松平常的东西，但在不久之前，压缩食品只有宇航员才吃得到。现如今，任何人在任何一家商店都能买到压缩食品。或许它没有被装在真空管里供人食用，但是当你饿了的时候，它保管是道美味。

粒子加速器

大约在十年前媒体宣布这项计划的时候，人们在意识到科学研究已经走了有多远后，整个世界都沉默了。用人造机器就几乎追上了光速，这真的使全人类都觉得我们好像是在参演一部科幻电影。然而，这不是一部科幻电影，这是一台真实存在于2017年的机器。

Robots Exploring Other Planets

Arnold Schwarzenegger has been to Mars， at least in Total Recall. Who explored the planet first？ Humans ... with the help of their robot friends. You might not have noticed， but Curiosity has been on Mars for a while now， exploring it and discovering new things. Yes， robots exploring other planets is a science-fiction concept that has become reality.

8

Viewing Multiple Channels at Once

You might have wished， when you were little， to have the possibility of viewing multiple TV channels at once—or at least stop arguing with your family about whose turn it was to choose the channel. This seemed like a technology of the distant future or of your science-fiction imagination. However， most televisions purchased today have this function， and all cable companies offer this option.

Concentrated Food

It might seem a banal9） thing in this list of science-fiction marvels， but concentrated food was only available to astronauts not long ago. Now， it is available to anyone， in any store. It might not be served from a tube， but it sure is delicious when you are hungry.

10

Particle Accelerator

When the press announced the project， around 10 years ago， the world became mute10） when realizing how far scientific research has gone. Almost reaching the speed of light using man-made machinery really made the whole of humanity feel as if we were taking part in a science-fiction movie. But this is not a science-fiction movie. This is a machine that exists in 2017.endprint
