The summer vacation is over. It is true that time always flies fast. During the vacation , the weather was bad and I could not do much work, but I live happily.

As the afternoon was hot, I did my work in the morning. I used to get up at 6:30 and take a walk in the garden for half an hour. After breakfast, I began reading English and Chinese and did some exercises in maths. This took me three hours or more. I worked quite hard and made good progress.

I spent the afternoon outside. I went to swim and it was very funny. I would not go home until it was five or six o’clock. Sometimes a friend would come to see me and we would spend some hours listening to music.

In this way, I spent my vacation happily. And I not only studied well but also became a good swimmer. Now I am in good health and high spirits.
