Task 1. Reading
Read the text. Do the task below.
My hobby is reading. Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. It’s not true. Television has not killed reading, however. Books are the cheapest way to get information and entertainment. Books at home are a wonderful source of knowledge and pleasure, and some types of books should be in every home.A good encyclopedia is useful, too, because there you can find information on any subject. It is important to have some fiction on your shelves, too. Then you can relax with a good story, or from time to time you can take a book of poems off your shelf and read the thoughts and feelings of your favourite poets.
Also I like board games. I can play Monopoly or Scrabble with Dad or Mum. I also have Trivia quizzes or the Millionaire. These are my favourite games that have cards with lots of questions about sport, people and the world around us. They are great!
