Miss Lin finds a water bottle after the trip. I try to help.
Miss Lin: Sam, look at this green water bottle. Is it 1 ?
Sam: No, Miss Lin. This water bottle is not 2 . My water bottle is blue.
Miss Lin: Whose water bottle is it?
Sam: Amy has a green water bottle. Maybe it's 3 .
Miss Lin: Where is Amy?
Sam: I think she is 4 in the school library now. She often reads a book 55:00 p.m. l can go and ask her about this water bottle.
Miss Lin: That's very kind of you, Sam. Thank you.
