Looking into the Future
Exchange views on smart homes
1 Before you read, discuss these questions in groups
1 What does it mean when we say that something such as a phone is “smart”
To say that something is smart means that it can make decisionson its own without a human telling it what to do, and that it canalso leamn how to do things itself.
2 What do you think a “smart" house can do that other houses cannot
I would expect that a smart house could control room temperatureand lights, for example.
2 Skim the text and answer these questions.
1What is the purpose of the text
The purpose of the text is to introduce and get people excitedabout the idea of smart homes.
2 Who is the intended audience of this text
Home owners.
SMART HOMES TO MAKE LIFE EASIER
Have you ever forgotten to lock the door of your house Or, have you ever forgotten to switch 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 not-too-distant 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 secure, save us energy and provide a more comfortable environment to live in.
Intelligent Controls
Today, we have to use switches for our lights, knobs for our appliances, and remote controls for our TVs and air conditioners. In the future, we will be using advanced technology every day for automatic control of just about everything in our home.
The future home will use integrated sensors to tell when you leave home each morning, and then go into an energy-efficient mode all by itself.
You will no longer have to think about turning switches on and off yourself. Your home will also learn your daily routine and preferences, so everything will be ready for you when you get home each evening.
Your lights will come on the instant you enter the door along with your favourite music or TV programmes, and you will find your dinner already prepared for you.
All controls will respond to voice commands, so if you want to change your routine, you just say aloud what you want and the home system will obey.
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 warning to your phone.
It will also give you suggestions on a healthier diet and how to sleep better.
Smart toilets will be keeping constant track of your health as well. They can warn you early on if there is something abnormal or if you have a critical illness, such as cancer, and potentially save your life.
No More Disasters
Smart homes will be able to prevent serious damage from accidents. For example, if a water pipe starts leaking, or if there is a short in the electrical wiring, your smart home will detect it and provide you with the relevant information.
This way you will be able to fix the problem before your home becomes flooded or catches fire. This smart technology is not a fantasy. Many of these new innovations are already available and being used in some homes. In this sense, the home of tomorrow is already the home of today. Nevertheless, it will take some years before most new homes begin to use this new technology.

Such smart homes could even be programmed to you d___________ your health problems, and then give you r_____________ advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.
5 Work in groups. Discuss these questions
1 In what way is the home of tomorrow already the home of today
Many of the new innovations are already used in some homes today. This is true especially of automatic controls for things such as lights and air conditioners.
2 What might be some of the disadvantages of smart homes
One disadvantage is that if there is a problem with the system ,you may find yourself locked out of the house , or unable to turn your TV off or on. Security is another big concern, as strangers may be able to hack into the system to collect information about your life and use that for evil purposes.

4 Work in pairs. Discuss whether you think Dr Han and Vincent Black's predictions are possible. Why or why not
I agree on Dr Han's idea that computers will be cleverer than us inthe future. Actually there are already computers, like AlphaGo,that are smarter than most people.
I don't agree on Vincent Black's idea about floating cities, becauseI doubt that sea levels will rise that much.

SHOULD WE FIGHT NEW TECHNOLOGY
This morning, I saw the shocking headline: “Passenger Dies When Car Crashes in Driverless Mode".
In the article, various people said that the public should oppose the idea of developing driverless cars.
They said that some advances in technology were unnecessary and could even be dangerous.
Hence, we should cease accepting technology just because it is new.
The newspaper reported that the car company had already apologised for the accident,
but the families of the deceased said it was not enough. Nevertheless, the company still claimed that most people would be travelling in driverless cars one day soon.
On the one hand, there are many different groups of people around the world who live happily in the absence of new technology.
Probably the most well-known are the Amish, a group of Christians living in rural America. They do not own or drive cars, watch TV, or use the Internet.
They have lived mainly as farmers since the 18th century, and they will probably be living the same way in the distant future. They advocate a simple life with an emphasis on hard work, family, and community.
They think that is better than caring about luxuries or following the lives of the rich and famous.
It could even be argued that the Amish's quality of life is better since they live in and appreciate the natural environment rather than living in large, polluted cities.
On the other hand, new technology has provided people everywhere with many benefits over the years.
For example, the latest weather-tracking computer programmes give people lots of warnings about potential natural disasters, which saves many lives.
Moreover, the Internet has made it possible for friends and family to keep in touch easily even if they are on opposite sides of the world.
It has also made finding opportunities in life much easier, as it allows people to make larger networks of friends through using social media. Personally, I have benefited quite a lot from technological advances. I found my career as an AI designer through a social media network. My health monitor, which I wear all the time, has also helped me get into the best shape of my life.
Of course, when new technology changes the way we live, it can be a scary prospect.
Nevertheless, I will always look on the positive side of change and accept it rather than resist it.
①A person died in an accident while driving a car. T/F
②The Amish avoid new technology because they do not want to have good lives. T/F
③Many disasters have been prevented by weather-tracking computer programmes. T/F
④Building large networks through social media helps us find new opportunities. T/F
⑤The author uses a health monitor to know how much exercise he/she needs. T/F

Use the letter below to help you.
Dear Past Bingbing
Hi! I'm Bingbing, your future self!
I know that you are really worried about your future career, so I wanted to write this letter to put your mind at rest.
I'm sorry to say that you won't become a pilot as you wanted. In the future, large passenger airplanes will fly themselves and won't need pilots. But there is a big problem in the future that you don't have now:
no one uses cars anymore-they use personal jetpacks. As you can imagine, the skies over the city get pretty busy!
Someone needs to control all these people so they don't have accidents. And that' what you do: you're a jetpack air traffic controller.
One really good point about your job is that you don't have to leave home. Instead, you’ll use a virtual reality headset and microphone to do your job while you are sitting on the sofa drinking tea.
But you will have to work on your people skills, as you will be talking to people all day.
The bad point Too many jet packs in the sky! Sometimes it can be kind of tense, and some people don't like to obey the rules or be told what to do.
All in all, I think you'll be happy with this job. But of course you will, because you're me!
Stop worrying! Your future is going to be great. Trust me.
Best regards
Future Bingbing

AFTER YOU WATCH
Discuss these questions in groups.
1 What might be some advantages of having many small robots that work together rather than one large robot
A large robot often takes up too much space and has difficulty inmoving.Small robots working together can easily enter a smallspace and move around.
2 Specifically, how might RoboBees be used in a future application
They might be useful in rescue after a disaster. For example, if abuilding was blown down in a storm, they could fly into thewreckage and check for survivors.
3 What other kinds of robots can be created from nature (e.g., a robotic lion or snake) How might these robots be used
A robotic spider could be useful as it could carry things acrossdifficult uneven surface where wheeled vehicles can't go.
