( 34.~35.) Hi, I am Jamie. My special place is in a big apple tree by my grandparents' garden. My grandpa built it for my sister and me. To get there, I have to climb up a ladder. Grandpa built it with wood and it also has a roof, so we don't get wet when it rains. I like to sit inside when it rains. The sound makes me comfortable. Sometimes I have food with my sister and cousins there. One day, I wanted to spend the night there, but it was really dark. I was afraid, so I went back to the house. vobiulp? Hi, my name is Karen. My special place is in a park near my home. I go there with my friends. It is not in the center of the park, so few people go there. There is a bench under a tree, and we often sit and talk there. It makes us very happy. There is a beautiful fountain and we often play water in it. It is a great place when the weather is hot. The tall trees there can help us keep out of the sun. In the spring, there are many beautiful flowers. It is more like the country than a park in the city. ladder 梯子 wood木材 roof屋頂 fountain 噴泉 34. Which is the right picture of the special place?
