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

在電影《回到未來》上映（編注：1985年）之后，大街上沒有孩子不想要一個懸浮滑板。它們看起來像滑板，但是比滑板酷多了。難道你沒想象過你原本可以用這樣一個懸浮滑板做什么嗎？好吧，它們確有其物！誰知道它們何時會成為下一個風靡全球的潮流呢？endprint

蚊子無人機

那些無人機沒有給你留下深刻印象？好吧，我想說2017年我們有了蚊子無人機。是的，看起來像蚊子的小無人機。別擔心！它們可不是用來咬你的——盡管它們可以——它們主要用于拍照和追蹤動態(tài)。

3

全息顯示

全息影像是每個人所能想到的最具科幻性的東西之一，其所需的知識和技術似乎還屬于遙遠的未來。但是就像3D打印機一樣，擁有全息顯示的小玩意兒眼下就有，你還可以給自己買一個。

4

云數(shù)據(jù)存儲

你或許沒有意識到，但我們存儲數(shù)據(jù)的方式可是極具未來感的。沒有電線，沒有物理空間，只是一片“云”就能讓所有數(shù)據(jù)都存在這里，并且可以從一個地方轉(zhuǎn)存到另一個地方。甚至連移動設備都具有這一功能，而這些技術在你祖父母還年輕的時候可是極具未來感的。

5

自清潔的門

清潔需要時間，而且比起整天做家務，我們寧愿做更富有成效、更有趣的事情?？墒?，能夠自清潔的物品似乎是科幻大片里才有的東西。不過，現(xiàn)在再也不是了。如今我們可是擁有能夠自動消毒的門把手了。

6

自動系鞋帶的鞋

除了可自動清潔的物品外，要是有自動系鞋帶的鞋子豈不是也很好？你或許記得《回到未來》里那些看起來超酷的鞋子。嗯，耐克在2016年就發(fā)布了這樣一款鞋子。如果你想體驗馬蒂（編注：《回到未來》男主人公）的感覺，現(xiàn)在就買一雙吧。

7

探索外星球的機器人

阿諾德·施瓦辛格曾去過火星，至少在《宇宙威龍》里去過。那么，誰是第一個探索這顆星球的？是人類……在他們那些機器人朋友的幫助下。你可能沒有注意到，“好奇”號火星車（編注：NASA于2011年發(fā)射到火星的探測器）如今已經(jīng)在火星上有一段時間了，它還在探索著這顆星球并發(fā)現(xiàn)新的事物。是的，探索外星球的機器人這一科幻概念已經(jīng)變成現(xiàn)實啦。

同時看多個頻道

在你小的時候，你或許希望，可以的話能夠同時看多個電視頻道——或者至少不再和你的家人爭論輪到誰選擇頻道了。這看起來像是一種屬于遙遠未來或者是你那科幻小說的想象中才有的技術。然而，現(xiàn)在賣得最多的電視就有這一功能，而且所有的有線電視公司都提供這一選擇。

9

壓縮食品

在本文列舉的這些科幻奇跡中，壓縮食品可能看起來只是一個稀松平常的東西，但在不久之前，壓縮食品只有宇航員才吃得到?，F(xiàn)如今，任何人在任何一家商店都能買到壓縮食品。或許它沒有被裝在真空管里供人食用，但是當你餓了的時候，它保管是道美味。

10

粒子加速器

大約在十年前媒體宣布這項計劃的時候，人們在意識到科學研究已經(jīng)走了有多遠后，整個世界都沉默了。用人造機器就幾乎追上了光速，這真的使全人類都覺得我們好像是在參演一部科幻電影。然而，這不是一部科幻電影，這是一臺真實存在于2017年的機器。

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.

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
