the summer vacation is over. during the vacation, the weather was hot, but i enjoyed it very much.
as it was hot in the afternoon, i did my work in the morning. i usually got up at 6:30 and took exercise for half an hour. after breakfast, i began reading english and chinese and did some exercises in math. those took me three hours or more. i worked quite hard and improved a lot.
i spent the afternoon outside. i went swimming and it was funny. i did not go home until five or six o’clock. sometimes my friends came to see me and we spent hours listening to music.
in this way i spent my vacation happily. i made much progress(進步) in my studies and i became a good swimmer as well.
