Reading strategy
Read the transcript of a podcast interview to learn about how the internet will further change our lives.
Smart life in the future
Host: Our guest today is Dr Li, a technology expert. Dr Li has studied how the internet will further change our lives in the future.
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.
While-reading
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 the rubbish collection company to plan better collection routes.
Dr Li’s opinion
an example to support this opinion
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!
