Прочитай текст. Выполни задания.
Once upon a time in a faraway forest there lived two little rabbits Billy and Willy. They were brothers. Billy was brave but Willy was afraid of everything. Every morning Billy skipped to the forest or to the field. In the evening he told Willy about his trips. Willy liked to listen to his brother's stories. Every day Billy said to Willy, "Let's skip to the field together! It's so interesting to visit new places and meet new friends!" But Willy stayed at home.
One day Willy was alone in their little house, he sat at the window and began to look at the field. It started to rain. Willy was nervous. He thought: "Rain! It's terrible! Where's Billy?" Willy was afraid of the rain. But he took the umbrella and skipped to the field. Soon the rain stopped. Willy looked around. He saw his brother under the bush. "Are you OK? I brought you the umbrella?" said Willy. "Willy! I am glad to see you. Oh, look at the sky!" said Billy. "Wow! What is it?" asked Willy. "It's a rainbow (радуга). Do you like it?" said Billy. Willy was happy to see the rainbow. It was so colourful and nice. "Now I will skip with you to the forest and to the field every day. There are so many interesting things I can see," said Willy.
"Great! Let's skip to the farm tomorrow! There are a lot of tasty apples in the garden!" said Billy.
