Đáp án: A. Smart home technology

Nội dung bài nghe:

Imagine living in a house where everything is controlled from a distance.

The doors and windows open and close not with keys, but with your voice commands.

The lights turn on when you enter the room, and then turn off as you leave.

The alarm rings when someone breaks into your house, and the police are immediately informed and on their way.

You can even control your house temperature, lights, and devices from a mobile phone when you are far from home.

That is what we call a smart home.

And that's how technology can make our life at home more enjoyable and comfortable than ever.
