Reading Read the text and answer the questions. My name is Ana Sanchez. I hope you enjoy my blog. Let me tell you a little about myself. I come from Colombia, so my first language is Spanish and I also speak some Portuguese and some English. My favourite classes at school are History and Geography. At the weekend I go to a sports club near our flat where I play a lot of sports, especially tennis and swimming. I live with my family in Bogota. Most years we stay in Colombia during the summer break. I like that because we have great beaches here. But last summer we went to Florida. That was the best trip ever! There were lots of great things to do there. My little brother loved this place where you could see sharks and other sea animals. I thought it was awesome too but my favourite thing was watching some amazing Japanese drummers performing. Even Dad said he'd never seen anything like that before. Mum said she enjoyed visiting the Space Center most. While we were having fun in the U.S., my grandma stayed in our flat to take care of my cat, so I really wanted to get her a special gift. I got her a nice scarf which is a really pretty shade of purple. It was made by a local fashion designer and it's beautiful. In a few days I'll be starting my last year of Secondary School. After that, I'm not sure what I'm going to do. I'd like to go to college but I'm not sure if I want to study business or law. My cousin has been studying law for the last two years and she thinks I should join her, but it sounds like a lot of hard work. So I think I'll probably go with my other idea. Anyway, that's enough about me! But please send me ideas to improve my blog. This is the first time I've ever written anything like this. Write a short answer to each question. 1 Does Ana know who she is writing to? 2 Which language does Ana speak best? 3 When does Ana go swimming? 4 Where does Ana usually spend her school holidays? 5 What did Ana especially enjoy on her last summer holiday? 6 Why did Ana want to get her grandma a nice present? 7 Where was the present which she bought produced? 8 Where will Ana be next week? 9 What subject is Ana probably going to do after leaving school? 10 Why does Ana ask for feedback from her readers? 10​
