Unit 16 Stories Warm-up Tapescript 1 It was a dark and foggy night. We drove and drove. At midnight, just as we thought we were lost, we saw a light behind some trees. As we got nearer, we could see a house. It looked abandoned. We knocked on the heavy door. It opened slowly. A tall man dressed entirely in black stood there. ―Good evening,‖ he said in a slow, deep voice. ―I've been expecting you.‖ 2 We were travelling through deep space at the speed of light. Suddenly, the spaceship slowed down and immediately the system came into view – a bright star with twenty or more planets. One of these would be our new home, five light years from our own planet. 3 One of my earliest memories is of my father running along the beach with our dog, Tess. I must have been about three years old. I remember the dog jumping up on me and knocking me over into the water. 4 The man lay on the ground next to a white truck. There was no doubt. He was dead. I quickly looked in the pockets of his jacket – some money, a handkerchief and a theatre ticket with a Chicago phone number

Unit 1 Lifestyles Warm-up Tapescript 1 Football player: Being famous isn’t easy, you know. I travel a lot – I have matches in different countries. But my job is exciting, very exciting! I love the matches, the people cheering, know what I mean? 2 Student: My dad says these are the best days of my life –but I’m not so sure! You know, I’ve got lots of work to do and there’s not much time really. I also play football for the school team and we have to do training three nights a week. 3 Shepherd: I love th e animals and I love nature. It’s peaceful, and there’s no one to tell me what to do. But it’s not so good when the weather’s bad! 4 Business manager: I’m very busy, and I don’t have time to see my husband and children. Mmmm and my life is very stressful, I suppose. I mean, I have to deal with lots of money. But I find it really exciting. 1 A Perfect Day? A Couch Potato Forty-three-year-old Brian Blakey from Birmingham is sitting on his sofa and telling me about his perfect day. When I wake up I don't get up immediately. I turn on the television and watch the children's programmes and old movies until about half-past ten. Then I get up, go downstairs and switch on the TV in the living room. For lunch, I have biscuits and a glass of milk, and I watch the news. In the afternoon, I often watch another old film – they're showing some good ones at the moment. In the evenings, I often watch TV series or sport and the news again. I like the main news at six o'clock. At nine thirty, if there is a good play on BBC 2, I switch over and watch it. Then at night, I watch more films and I usually switch off the TV at about two o'clock. I never watch TV all night. I watch TV for sixteen or seventeen hours a day. I also do some exercise every day. I take Tina, the dog, for a walk every afternoon. I don't go far, of course. I walk to the wall outside my house. I always take my portable TV and I sit on the stone wall while the dog walks round in a circle. Of course, I couldn't live this lifestyle without a good wife. She's not here now because she's working, but she always makes my meals. We haven't got much money, you know, but we're happy. Sit down and watch TV. Here's the remote control. You've got the world at your feet. And in your hand. Great! A Workaholic Thirty-six-year-old Bob Black is sitting at his desk and working his way through his paperwork. I normally wake up about five minutes before my alarm clock goes off. As soon as I hear my alarm clock, I jump out of my bed. It takes me less than fifteen minutes to wash, get changed, have breakfast, leave home and get on a bus. I am always the first person to get to the office. The mornings are always very busy and the afternoons are even busier! Meetings and phone calls take up a large part of the day. Every minute
模块3 U7 L1 1 The Spirit of Explorers Viking Voyages to America The Vikings were the first Europeans to reach America. They achieved this long before Columbus ever set sail. The Vikings were a group of people whose ancestors came from Scandinavia. They controlled the seas and coasts of Northern Europe between the 8th and 10th centuries AD. By around 900 AD, there were many places in Northern Europe where the Vikings chose to live. In 982 AD, when a man called Eric the Red decided to set sail further west, there were as many as 10,000 Vikings living in Iceland. According to the old stories of Iceland and Norway, Eric the Red was forced to leave Iceland because he had committed a murder, for which he got into trouble. Eric reached Greenland and discovered that people could live in the place where he landed. He returned to Iceland and told people there about Greenland. He persuaded some people to go back with him to Greenland. Eric set sail once again, this time with 25 ships, of which only 14 made it to Greenland. Not long after Eric the Red had landed in Greenland, a man called Biarni set sail from Iceland in search of Eric's party. Biarni was hoping to join his father who was with Eric, but he was blown off course and found himself in an unknown land, from where he eventually reached Greenland. In the year 1002, when Eric the Red's son Leif was planning a trip further west, Biarni was the man with whom Leif discussed his plans. Leif followed Biarni's directions and sailed to what is believed to be the coast of present-day Canada. He then sailed further south to an island which is now known as Newfoundland. We know about Eric the Red and Leif's deeds through stories which were written down centuries later in Norway and Iceland. They are the first records we have of Europeans sailing to the Americas. U7 L3 3 The Sea World UNDER WATER WORLD The Best place to See Sea Creatures Polar World We have polar bears and a real iceberg too! You can only see a small part of it above the water. It's three times as big underwater. Watch the acrobatic seals at feeding time. Meet our less energetic but more friendly penguins. You'll love them! Ocean Floor See some of the most beautiful coral and the most unusual fish in the world. Watch some fish “flying” through the water. They are less colourful than some other fish but they move beautifully. Sea Theatre See our intelligent dolphins. There are fantastic shows every two hours. Discovery Pool Especially for younger children. They can touch crabs and other smaller creatures. They can be educated about daily life on the beach in this exciting area. Virtual Reality Voyage Our most up-to-date attraction. Come with us on a “virtual reality” trip to the ocean floor and see some of the strangest fish in the world.
