Read the text and for questions 1-5 choose the correct answer (A, B or C).
Hi Saule,
How are you? I’m in Venice for a short holiday and decided to drop you a line to tell you about it. I’ve never been abroad before and it’s exciting!
We’re staying at a beautiful hotel on the Grand Canal. It was built nearly a century ago and it used to be a palace. The rooms have all the original decorations and lots of old furniture. The weather has been good for this time of year but it did rain a bit yesterday. Today, it’s warm and sunny. I hope it stays this way.
Yesterday, we visited St Mark’s Basilica. I loved all the mosaics. Afterwards, we went to the Doge’s Palace too. We even walked across the Bridge of Sighs, which prisoners crossed on their way to their awful cells. St Mark’s square was very crowded. There are so many tourists here. Then we went for a trip down the Grand Canal. There are so many beautiful buildings and it’s great getting around in the water taxis. I’m going to hire a gondola today too. Later we are going to go visit Murano, where they make all the famous Venetian glass.
I’ll bring you some souvenirs made from Murano glass. They have so many pretty things!
All the best,
Dana
