Kelly was excited. She was on holiday with her family in a fantastic place - Rio in Brazil, The hotel was wonderful. There was a swimming pool and a garden, and it was near the beach! Kelly's brother Steve was excited too. It was carnival time in Rio and that night there was a big party in the street. Everyone had wonderful

clothes in different colors - green, blue, red, purple, and even gold and silver. Kelly and Steve wanted to go to the party but they didn't have any carnival

clothes. 'Let's go to a shop and buy some costumes,' said Steve. So they went out

of the hotel and into the shopping center. All the shops had fantastic clothes. They went into a big shop, Kelly put on a costume - there was a special jacket, a short skirt, a blue T-shirt, white boots and a cowboy hat. She looked in the mirror.

"Ha ha, you look terrible!' said Steve. Steve put on a costume - a pair of red and

yellow trousers, a green and red spotty shirt, blue shoes, a silly hat and a red nose. "That's good! You look like a clown!' said Kelly. Kelly bought a gold-colored dress and silver shoes, and Steve bought a Superman costume. Now they were ready for the party! They went back to the hotel. When they arrived they saw a tall, elegant woman in a black dress. She was wearing diamonds on her fingers, on her shoes, on her clothes and in her hair. 'Wow!' said Steve. 'Look at herl Who is

she?' 'That's Diana Diamond - the famous film star,' said the manager, 'The diamonds are famous - they cost thousands of pounds!' Kelly and Steve went to get ready for the party. At eight o'clock they went to the restaurant with their mum and dad to have dinner.
