А. He was very sad and went to the airline. They felt very sorry for poor Peter and found him a seat on the evening flight. Peter went home by taxi to wait for the evening.
B. Peter left the house at 10 o’clock in the morning and took a taxi to the airport. When he arrived and got out of the car, he decided to find his passport. Peter opened his bag but the passport wasn’t there. He became very unhappy! “What am I going to do!” he thought.
C. Yesterday Peter woke up early. He was feeling very happy. Finally it was the day of his trip to Russia. It was his childhood dream to visit this large and unusual country. His grandfather was Russian and he often told him Russian fairy tales about kind people, powerful kings and queens and wild animals.
D. Peter jumped up and down angrily. “Where is the taxi? Where is it!” he was crying. He ran down the street and looked for another taxi. After a few minutes, Peter found another taxi and told the driver to take him to the airport quickly. There were a lot of cars on the roads and Peter’s taxi arrived at the airport late. His plane left for Moscow at 11.30 and Peter missed it.
E. He jumped back into the taxi and asked the driver to take him home. They drove quickly and it took Peter twenty minutes to get back home. He ran into the house and went into his bedroom. He found his passport on the table and left the house again. But the taxi wasn’t there! Where is the taxi?
