Last Sunday, my friends and I went to a nature park. We went there     1    . There were green mountains around the lake. The     2     in the lake was green and clean. Lily and Jack went     3     by the lake. Li Mei and I went boating. We saw many animals there. Two monkeys     4     from tree to tree. We     5     lots of pictures. In the afternoon, we ate some     6     food. That was fun.

In spring, Mother Pig ______ the little pig Lulu to the foot of the ______. They ______ some watermelons. When summer came, there were many round watermelons in the field. Mother Pig asked Lulu to ______ one watermelon back. But it was too heavy. He couldn’t ______ it. Finally, he put it on the ground and rolled(滚) it back home. Mother Pig was so happy.
