Hi, boys and girls! Welcome to our museum. It's free. You don't have to pay any money. But we have some rules for you. Please remember them and do as I say. Firstly, don't have food or drink here. You may make our museum dirty. Secondly, you can take photos here, but don't touch   the things here. Thirdly, keep quiet in the museum. Don't talk loudly. Fourthly, the museum is not open after five o'clock in the afternoon. Please leave   before five. Have a good time here! Thank you. Students can  _  in the museum.
