Hello, Nancy. This is Bill. How are you?

Fine, but a little busy. I'm preparing for my maths exam now.

Oh, I'm calling to ask you whether you'd like to go to the movies this afternoon.

Sorry, I'm afraid not. I need to help my parents with housework this afternoon. And I really hope a robot can help us with housework in the future.

It's a nice dream, and I'm sure it can come true one day. A few days ago, I read something about Astribot.

Astribot? What is it?

It is a robot, and it's good at doing housework.

Really? What can it do?

It can cook food, feed pets and do the cleaning.

Sounds like a really great helper!
