     Today is Monday again and it's fine! We just had a test in the science class. I think I did really well. If

 I get a good grade, Mum will let me go to the basketball game next Friday. There I can see my favourite

 basketball player - Kobe. I can't wait!  

     I went to Mark's birthday party with Jenny and Billy on Saturday. I bought him a storybook. We

 listened to music and danced at the party. Then we sang "Happy Birthday" to Mark and had some cake. I

  did have a good time. I hope I can have a birthday party like that when my birthday comes. And I hope I

  can get a new bike on that day.

     Oh, the bell is ringing! It's time to go to the maths class. I hope I don't fall asleep in class!
