Перевидите текст When Miss Huckleberry was my teacher, our lessons were fun. One day we read about animals in the zoo and Penny said, "Why can't we have a zoo in the room?" Miss Huckleberry said, "We can." I said, "I have a big black dog and three cats." My friend Bill said, "I have a yellow bird." Then Penny said, " These animals don't live in zoos. They are pets, not zoo animals." "We will make the zoo animals," said Miss Huckleberry. Make zoo animals? Penny said, "Clay!" I brought the clay. Other children took paper the and dishes of water. Some children took the clay and made small animals. Some other children took the clay and made big animals. One boy made the hippopotamus. He made it very well. Another boy made the monkey. But the monkey was bigger than the hippopotamus! And the spider was bigger! The best animal was my elephant. It was the largest animal in the zoo. Miss Huckleberry helped us a lot. Then I made a lion cage from a hat box. A girl painted a dish blue. It was the water for the little hippopotamus. My friend Bill made a monkey house.Penny helped two other girls to write signs for the cages. Penny was good at spelling. She spelt " hippopotamus". Then we thought about the name for the zoo. Penny made a big sign and put it on the door of the room.
