I am going to have my summer holidays very soon. My family and I are going to the seaside in June. We are going there by train. I am going to swim and sunbathe there. My parents are going to visit famous landmarks. In July I am going to stay at my granny's place. I am going to help her in the garden. My granny and I are going to plant trees and water the flowers. My parents are going to repair our flat at that time. In August I am going to spend time in our city. I am going to play computer games and watch TV. My friends and I are going to walk around the city. Our family is also going to watch plays at the theatre. My best friend and I are going to play football. At the end of summer I am going to prepare for school. I am going to buy exercise books, pens and pencils.
My favourite book It’s impossible to be an educated person without good books. Most of the books are to be read just once, others can be read plenty of times. And each time you find something new and useful as you turn the same pages of your favourite books. I am fond of books about adventures and great people, detective stories and science fiction. I enjoy reading them when I have spare time.
But my favorite book of all times is a novel “Three comrades” written by a German writer Erich Maria Remarque. This book was recommended to me by my elder sister and I’m grateful to her for that advice. It was really worth reading.
