Miss Lan: Class, why don't you come one by one and show us your favorite photos of a robot?

Ba: Yes, Miss. I'll go first. Hi guys, here is a photo of our house's robot cleaner. It helps us keep the house tidy and clean.

Nga: And here is Pepper, a robot from Japan. He knows if you are happy or sad, or even angry. He's really smart.

Michael: You will be surprised to see this, guys. Here is a picture of the da Vinci surgical robot. It could assist doctors to do surgeries for sick people.

Miss Lan: Well done, everyone. You did your research well. I have one more question for you. What do you think about the role of robots in the past?

Daisy: Me, me... They could only do very simple tasks, but now they can do quite a lot. I think they will be able to do many difficult things in the future.

Miss Lan: Sure they will. Good job everyone. Now, I'd like each of you to write about a robot you want to create in the future. What will it look like? What will it be able to do? ...
