17 II. Read the email and mark the statements I (true) or F (false). From: Laura To: Suzanne Subject: My Favourite Places Hi Suzanne, Thanks for your email. I want to tell you about my two favourite places in my country. There are a lot of beautiful and interesting sights in Ireland, but I really love Cork and Glendalough. Cork is on the south coast of Ireland. It's not the biggest city in Ireland, but it's very busy. When I go there, I like to go shopping for clothes in St Patrick's street. I also buy delicious fish and a meat at the food market in Herry Street. I always have a fantastic time there. Glendalough, on the other hand, is in the countryside. so it's much quieter than Cork. There are many lakes, rivers and even waterfalls in the area. When I go there. I always take long walks with my dog and enjoy the fresh air. Also, I sometimes go rock-climbing. It's very exciting. Glendalough is a beautiful place and I think the people there are the friendliest in the country. What about you? Which places in your country do you like the most? Write back soon. Best wishes Laura. 1. Cork is a city by the sea.
