If these three pictures were from the same story, which one do you think might come first Why
I think Picture B might come first because the man in Picture C is running, and in Picture B, we can see an alien is running after him.
I don’t agree. I think Picture A must come first. In Picture A, we can see a UFO landing. The UFO has to land before the alien can come out and run after the man.

Post-listening
Yesterday, Tom and I had an unusual experience. When we were walking on the street, we saw a man running down the street. I thought he could be running for exercise, but Tom said that he might be late for work, because he was wearing a suit.
Just then, we saw something in the sky. Tom thought it could be a plane, but I thought it can’t be a plane because it was too big. In my opinion, it must be a UFO.
Then the UFO was landing and there was something strange getting out. We both believed that it must be an alien until we saw a woman with a camera. We guessed that she could be from the TV news. Finally, we were sure that they must be making a movie.
Role-play a conversation between the man and the woman.
