Minh: Ann, do you like yesterday's lesson? I really enjoy learning online.
Ann: I prefer having face-to-face classes. I like to interact with my classmates during the lessons.
Minh: I think online classes are convenient during bad weather or epidemics. Also, students can still interact when they are in breakout rooms.
Ann: But the Internet connection doesn't always work well enough for us to learn online. And my eyes get tired when I work in front of the computer screen for a long time.
Minh: I know what you mean. But there’s some great news for us. 3D contact lenses will soon be available. With them, our eyes won't get tired when looking at a computer screen all day long.
Ann: Wow, that’s brilliant!
Minh: Another helpful invention is robot teachers. They will teach us when our human teachers are not available or get ill. My uncle said the robots would be able to mark our work and give us feedback too.
Ann: Fantastic! I can’t wait.
