Ladies and gentlemen,

Welcome on the Museum of Natural History! I'm Joe Smith. Let me tell you about some of the thing you should not miss here.

Here in the Entrance Hall, you can see some beautifully paintings of flowers and plants. Upstairs on the left are a famous animal exhibition. I can see the models of some dinosaurs and some strange animals. On the right, there is a small theatre, where you can watch a movie about what our planet looks like millions of years ago. The film that lasts 45 minutes plays every hour. After you leave this museum, please don't forget visit the shop inside it. Some wonderful models of animals, T-shirts or many other things can be bought there.

The museum will be not close until 5:00 pm, so enjoy yourselves.
