My family went on a trip last Saturday. We didn't 1 much money and really had a good time. In the morning, my father 2 us to a science centre in our city. We didn't 3 any money on the tickets 4 it is free. There is a 5 area in the science centre. My brother and I saw different kinds of animals and did some 6 things. We both had a lot of 7 playing together in the science centre. Then we took 8 car to a park near the science centre. My parents set up the tent 9 and then we had a picnic 10. After the picnic, my father started to read newspapers and my mother 11 games with me. After we got back home in the afternoon, I turned 12 the computer and copied (拷贝) all the photos we took that day. My mother even wrote some words for our 13. She hoped those 14 and words would 15 us remember the happy time.
