I remember that during the summer holidays, the weather was hot and I could not do many work, but I lived happy. In the morning I usually get up early and took a walk in the garden. After breakfast, I began read English and did some exercises in math. I worked hardly and made a great progress. I spent nearly the whole afternoon outside. I went swimming on the river and didn’t come back when it was about five or six. Sometimes a friend of me would come to see me and we would spend some hours listening to music. In this way I spent my holidays happily. I not only studied well and but also became a good swimmer.
