Exercise n.7 page 33 from "Preliminary for schools trainer"

I'm very happy that you're going to come here next summer. In my town there are a lot of old buildings and they're all beautiful. There is "Piazza dei Miracoli" which includes the Duomo of Pisa, the strange tower which is famous in the whole world because it's retort, and an amazing big green park. There are also many activities that you and your brother will enjoy, for example you can visit all the town in bike: it's very hard but also really interesting. Then you can visit "Il Palazzo Blu" where there are some exposure of famous artists.
See you soon, bye!
