Перевидите текст! Прошу( It was the first day at school. It was nine o'clock. All the pupils were in the classroom. They knew they had a new teacher — Miss Chatter.After the bell Miss Chatter came into the room. She was kind and nice."Good morning, children," she said and smiled. The lesson began. But the pupils didn't do what their new teacher said. They spoke loudly and ran in the classroom.Suddenly it became dark and very cold for a minute. The pupils sat still at their desks and looked at Miss Chatter.Their new teacher took Oliver's pen, looked at it and said: "Three, two, one!" The blue pen became red and turned into a nice red umbrella. Miss Chatter took the umbrella and touched Oliver's chair. The chairs began to dance with the children sitting on them. Oliver was happy. All pupils laughed. Soon all the chairs and the pupils danced in the classroom.Miss Chatter opened the umbrella and the rain of sweets began. The pupils were surprised but happy. "It's great!" Oliver said.In the second lesson Miss Chatter and her pupils counted white rabbits and black kittens in the classroom, read stories about whales, talked with the goldfish. Children answered her questions, drew on the walls of the classroom and learned funny poems by heart. The pupils had a good time. They enjoyed Miss Chatter's lessons.The next morning Oliver, Ann and their classmates ran to school. But there was a different teacher in the classroom — a new teacher."Where's Miss Chatter?" asked Ann."Who?""Our teacher — Miss Chatter!" answered Oliver."I don't know Miss Chatter. Let's begin our lesson," said the new teacher.The children were sad. But Oliver saw Miss Chatter's red umbrella in the left corner of the classroom. He smiled.
