UNIT 2　LOOKING INTO THE FUTURE
主题语境
人与社会——未来生活
背景导入：5G作为经济社会数字化转型的关键使能器， 通过与大数据、人工智能、云计算等技术的交叉融合， 赋能制造业转型升级和优化发展， 5G技术以及未来5G对我们日常生活的影响。




Forging a 5G future
The future in sci­fi movies seems so close, yet so far away. Delightfully, 5G technology makes that future look easily achievable①. Schools, hospitals, transportation, factories—even our homes will soon use this powerful wireless network. Last year, China started testing 5G mobile networks in its several cities. So what is 5G? It's the latest generation of cellular (蜂窝状的) network technology. It is faster and more stable than 4G, the previous generation.
5G's benefits mainly come from speed and connectivity②. The advantage of higher speeds is obvious. People will be able to use the Internet at a much greater speed than before. Imagine being able to download an entire movie in just a few seconds! That's how fast 5G will be.
With 5G, people can conveniently solve many problems.For example, one of the biggest problems with developing driverless cars is the delay between sending a signal and receiving it. Driverless cars③ must be able to react instantly to sudden changes in their environment, such as a dog running across the road.This will require these cars to send and receive huge amounts of data within milliseconds④. Such speed helps other technologies, too. It will also allow doctors to perform operations remotely, using robots. The robots will respond more quickly to the doctors' movements.
So what about 5G's connectivity？We may develop “smart” environments with it.Imagine having a smart home that automatically⑤ turns the lights on when you open your front door.
“New things become possible when you can move information at a massive scale⑥， ” Gordon Smith, CEO of telecom equipment reseller Sagent, told TheTelegraph.“5G becomes the great enabler.”
No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.


①achievable adj. 可完成的；可有成就的
②connectivity n. 连通(性), 联结(度)
③driverless cars 无人驾驶汽车
④milliseconds n．[计量]毫秒
⑤automatically adv. 无意识地；自动地
⑥at a massive scale 大规模地

[原文呈现]
SMART HOMES TO MAKE LIFE EASIER
Have you ever forgotten to lock the door of your house？Or, have you ever forgotten to switch① off the TV or computer？These kinds of things happen to us all the time, waste resources, and can sometimes lead to problems.However, in the not­too­distant② future, we will be living in smart homes that will lock the door for us when we are away and remember to switch off the TV when we forget. These smart homes will keep us secure③， save us energy, and provide a more comfortable environment to live in.
Intelligent Controls
Today, we have to use switches for our lights, knobs④ for our appliances⑤， and remote⑥controls for our TVs and air conditioners⑦. In the future, we will be using advanced technology every day for automatic⑧ control of just about everything in our home.The future home will use integrated⑨sensors⑩ to tell when you leave home each morning, and then go into an energy­efficient⑪mode⑫ all by itself. You will no longer have to think about turning switches on and off yourself. Your home will also learn your daily routine⑬ and preferences⑭， so everything will be ready for you when you get home each evening. Your lights will come on the instant⑮ you enter the door along with your favourite music or TV programmes, and you will find your dinner already
prepared for you. 1All controls will respond to voice commands⑯， so if you want to change your routine, you just say aloud what you want and the home system will obey⑰．
Regular Health Checks
In addition, your smart home will be monitoring your health for you every day. Your bed, for example, will record how well you sleep every night.It will also be checking your body weight. If you start to have sleep or weight problems, it will send a warning⑱ to your phone. 2It will also give you suggestions on a healthier diet and how to sleep better. Smart toilets will be keeping constant⑲ track of your health as well. They can warn you early on⑳ if there is something abnormal㉑or if you have a critical㉒illness, such as cancer㉓， and potentially㉔save your life.
No More Disasters
Smart homes will be able to prevent serious damage from accidents.For example, if a water pipe starts leaking㉕， or if there is a short in the electrical㉖wiring㉗， your smart home will detect㉘it and provide you with the relevant㉙information.This way, you will be able to fix the problem before your home becomes flooded or catches fire㉚.
This smart technology is not a fantasy㉛. Many of these new innovations㉜are already available㉝and being used in some homes.In this sense㉞， the home of tomorrow is already the home of today. Nevertheless㉟， it will take some years before most new homes begin to use this new technology.


[课文翻译]
智能家居让生活更轻松
你有没有曾忘记锁门？或者， 你曾经忘记关掉电视或电脑吗？这种事情经常发生在我们身上， 浪费资源， 有时还会导致问题。然而， 在不远的将来， 我们将生活在智能住宅中。当我们外出时， 智能家居会为我们锁门；当我们忘记关电视时， 智能家居会记得关掉它。这些智能住宅将保证我们安全， 节省能源， 并提供一个更舒适的居住环境。
智能控制
现在， 我们必须使用电灯的开关， 电器的旋钮， 电视和空调的遥控器。在未来， 我们每天都会使用先进技术对家中几乎所有东西进行自动化控制。未来的家庭将使用集成的传感器来告诉你每天早上什么时候离开家， 然后自己进入节能模式。你将不再需要考虑自己打开和关闭开关。你的家也会了解你的日常习惯和偏好， 所以当你每天晚上回家时， 一切都会为你准备好。你一进家门， 灯就会亮起， 还有你最喜欢的音乐或电视节目(会自动播放), 而且你会发现晚餐已为你准备好了。1. 所有的控制都会响应语音指令，所以如果你想改变你的日常工作，__你只要大声说出你想要什么，家庭系统就会服从。
定期健康检查
此外， 你的智能家居每天都会监测你的健康状况。例如， 你的床会记录你每晚的睡眠质量。它也会检查你的体重。如果你开始有睡眠或体重问题， 它会向你的手机发送警告。2. 它还会为你提供更健康的饮食和如何睡得更好的建议。智能马桶也会持续记录你的健康状况。如果有什么不正常的情况， 或者你有严重的疾病， 比如癌症， 它们可以提前警告你， 并可能挽救你的生命。
没有更多的灾难
智能家居将能够防止事故造成的严重损害。例如， 如果水管漏水或发生电线短路， 你的智能房屋将会探测出来， 并给你提供相关的信息。这样， 你就能在房子被水淹或着火之前解决这个问题。
这种智能技术不是幻想。许多这样的新发明已经可以使用， 并已经在一些家庭中使用了。从这种意义上说， 明天的家已经是今天的家了。然而， 要让大多数新家庭开始使用这项新技术还需要几年的时间。
