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 which one to buy, because these books were all useful to me. At last, I chose two. At 10:00, we went to the cinema. The film calling Titanic was very popular. It took us about 3hours to see. Having seen a film, everyone was deeply moved. Some friends even burst into tear. From the story, I understand that love is noble but valuable. That’s a real wonderful film. It is well worth seeing again.

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