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 center in our city. We didn't spend any money on the tickets, 3 it is free. There is a children's area in the science center. My brother and I saw 4 kinds of animals and did some interesting things. We both had a lot of 5 playing together in the science center. Then we took 6 car to a park near the science center. My parents put up the tent first, and then we had a picnic 7 . After the picnic, my father started to read newspapers and my mother played games with us. After we got back home in the afternoon, I turn 8 the computer and copied (拷贝) all the photos we took that day. My mother even wrote some words for our 9. She hoped those photos and words would help us remember the 10 time.
