2d Role-play the conversation.
Sandy: I'm really excited about seeing the famous paintings by Picasso.
Wu Lan: Me, too! I'm glad Mr.Smith chose the art museum for our school trip this year.
Sandy: I'm going to bring my new camera to take lots of photos!
Wu Lan: Oh, no. Mr.Smith says we must not take photos. It's not allowed in the museum.
Sandy: That's too bad! Do you think we may be allowed to take photos if we don't use a flash?
Wu Lan: Hmm…I think they just want to protect the paintings. So if you don't use a flash, then it may be OK.
Sandy: Yeah. I think we should be allowed to do that. I'll bring my camera anyway.
