暑假里的一天(A Day in My Summer Vacation) 
　　It was during the summer vacation. On a sunny morning, my parents were at work and I was playing the piano at home. Just then the phone rang. It was my aunt's voice. She said that she had to go to another city to do an important business, and her two-year-old boy needed to be looked after. She wanted me to babysit my little cousin for her.
　　My cousin was ready for bed. My aunt told me when to put him in bed. My aunt said that my cousin loved bedtime stories. She gave me her phone number. If I had any problem, I could ring her up.
　　Mom called me about three times while I was babysitting. She just wanted to make sure if everything went well. My cousin didn't even cry when his mom was away. I read her Goodnight, Moon and sang children's songs for him. I washed his face and changed diapers （尿布） for him. He didn't even cry when I put him in bed. I spent a happy morning with my cousin. I thought babysitting was fun.
