A: Look! There’s some object in the sky, there, above the hill.
B: I’m not quite sure, but it seems to be an airplane.
A: Oh, no, look, it’s flying too fast for a plane. It’s possible that it’s UFO.
B: Don’t be silly. I don’t believe in UFOs. I’m sure they are a fruit of people’s imagination.
A: What makes you so sure? Look, it’s coming nearer. It has a funny shape. It might be a big bird.
B: No, it isn’t. Birds move their wings. If this thing has wings, it doesn’t move them.
A: I’m certain that it isn’t a plane or a helicopter because there is no noise. I’m sure, it’s an UFO! It is so exciting!
B: Don’t speak too soon. It seems to me that it’s not. Wait! I see now! Now I have no doubt about it! It is a hang-glider!
