When everything was ready, we set out to bake bamboo tube rice on the back mountain of grandma’s house.　　When we got to the top of the mountain, we divided the work, and dad planed the pit. The width of the pit was about the same as the length of the bamboo tube. Now we ignited the fire. Dad lit the firewood with a lighter and put it into the pit. We were all busy putting firewood into it. The fire was fine at first, but somehow it went out. Dad said, “too much firewood causes hypoxia. Oxygen can help burn.” My father taught me that Yang Yibu gently picked up the firewood with a stick and then fanned it with a leaf. After fanning it for a while, the fire flared up again. At this time, my mother put the bamboo tube horizontally on the pit. After a while, the water in the bamboo tube boiled, and the water came out of the bamboo tube, squeezing out the sealed potatoes. I asked my father what was going on, and my father said the principle of heat expansion and cold contraction at this time. The bamboo tube rice is finally ready. I took a bamboo tube.

The school organized us to have a spring outing to fengle ecological park.　　Because I am having a spring outing with my classmates and teachers, I feel not to mention how happy I am. On the first night, I asked my mother to prepare a lot of delicious snacks for me. My mother said she couldn’t eat so much. How could she know that these delicious snacks I wanted to share with my classmates.　　The bus organized by the school took us straight to our destination. As soon as I got off the bus, I saw the words “fengle ecological park”. Fengle ecological park is actually a botanical garden. The flowers, plants and fruit trees here are unique because of their strangeness and particularity, which we rarely see in daily life. Please follow me to have a look.　　The first stop we entered was the tropical area. As soon as we entered, the giant cactus caught my eye. What a big cactus! I’ve never seen it before. Because of its particularity, I didn’t care to visit other scenery. Then we went to the melon and fruit picking garden. The strangest ones were crane head melon, mouse melon and snake melon. Their shape is so strange. Nature is also really magical. How can we make such strange melons and fruits? Finally, we arrived at the glittering beach. It was so magnificent! The sparkling lake is really dazzling. Some students play with sand, some wash their hands and feet by the lake, some are singing songs, and some are sharing delicious food with their good friends. The students
