Today is Sunday. The sky is full of sunshine, so does my life. At about 9:00 a.m., I go to the bookstore with

my friends. There was a lot of new books. I didn’t know what one to buy because these books were all useful to me. At 10:00, we went to cinema. The film was called The Earthquake of Tangshan but some people were waiting outside the booking office. It took us about two hours to see it. Having been seen the film, everyone was deeply moving. Some of my friends even burst into tear. That’s a really wonderful film. It is very worth seeing.

What a happy day! I hope tomorrow I will be even happier.
