3.Imagine it is 2035. You have a smart home system,and you
want to improve it
· What new devices need to be added to your smart home?
· How are these devices connected to each other?
· How do we make the system safer?
In a smart home,a lot of devices
are connected to the internet.You
can control these devices
even when you are not at
home.
Dr Li: That's right.The internet has brought big changes to everyday life.For example,e-learning and mobile payment have changed the way we study and shop.In the future,even more things will be connected to the internet,so life will
continue to change.
Host: Can you give us some examples?
Dr Li: Take health for example. We'll probably wear small devices all the time,and they'll check our health and warn us about health problems.With this information,doctors can provide better treatment.
Host: Interesting!Will the internet help improve the environment?
Dr Li: Yes!As more things become connected to the internet,our cities will become smart cities.Smart cities will be more
eco-friendly than cities today.One of the most important changes will come in energy use.Different devices will
communicate and share data with each other.This will help them save energy.For example,smart rubbish bins will
automatically tell the smart city network when they are full.This data will allow therubbish collection company to plan better collection routes.
Host: Will smart cities improve our lives in other ways?
Dr Li: I think the biggest change will be in transport.Our roads will be much safer in the future,and traffic will flow more smoothly. There will be fewer accidents because cars will drive themselves,and they will share data with the smart city network.With this data,traffic lights can change the timing according to the number of cars on the road.
Host: That's amazing.And will this really be possible?
Dr Li:Yes,it will.We've already started doing some of these things!
