it. When she opened up the oven, she realized she had invented the tasty treat called chocolate chip cookies!

      B. Computers originally began as calculators. The first calculator was made by Blaise Pascal. It only had eight buttons, and it could only do addition and subtraction. There was a set of wheels, and all of the wheels had the numbers zero through nine on them. The wheels were connected by gears and each turn of one wheel would turn the next wheel one-tenth of a turn. This machine was completed in 1642 when Blaise was twenty-one years old.

      C. A helicopter has a big advantage over an airplane, especially when people might be trapped in a tight place like on a mountain, where there is not much space to land, or on the water. They are also used for rescuing people from burning buildings or from trees when there are floods. Without the helicopter as a rescue vehicle, many people would lose their lives because the rescuers would be unable to reach them if they were in a difficult area.

      D. Cars have always caused air pollution. In the past, there was a lot more air pollution created by cars than there is today. In the future, there will probably be even less. Two good ways for pursuing the dream of less air pollution are cars that run on solar energy and cars that run on fuel cells. Solar energy and fuel cells don’t cause pollution because they do not give off any exhaust.

      E. Reporter Rob Spence is planning to have a camera embedded in his eye socket and become a «bionic reporter’. Spence, who lost one of his eyes when he was young, says he has a prototype in development and that one day the replacement of even healthy eyes with bionic ones may become commonplace. «It seems shocking now, but it will become more and more normal,» he said.

      F. Crop circles have been appearing in fields all over the world for the past 30 years. There have been suggestions that they are made by flying saucers landing and flattening the crops, or even that they are messages left by visiting aliens. Others think they are created by microwave beams from satellites orbiting the Earth. Other more rational suggestions are that crop circles are man-made hoaxes, attempting to convince the public of extra-terrestrial life on Earth.

      G. The Egyptian Pyramids have always been surrounded by mystery. When Egyptologists began to open the tombs of the pharaohs, rumours abounded that anyone who raided them would be cursed. Many think a curse was to blame for the death of Lord Carnarvon, who funded the expedition to open King Tutankhamen’s tomb in 1923. He died of pneumonia after being bitten by a mosquito a few weeks after the tomb was opened.

      The Hitchhiker

      As Andrea turned off the motorway onto the road to Brockbourne, the small village in which she lived, it was four o’clock in the afternoon, but already the sun was falling behind the hills. At this time in December, it would be completely dark by five o’clock. Andrea shivered. The interior of the car was not cold, but the trees bending in the harsh wind and the patches of yesterday’s snow still heaped in the fields made her feel chilly inside. It was another ten miles to the cottage where she lived with her husband Michael, and the dim light and wintry weather made her feel a little lonely.

      She was just coming out of the little village of Mickley when she saw an old lady, standing by the road, with a crude hand-written sign saying «Brockbourne’ in her hand. Andrea was surprised. She had never seen an old lady hitchhiking before. However, the weather and the coming darkness made her feel sorry for the lady, waiting hopefully on a country road like this with little traffic. Normally, Andrea would never pick up a hitchhiker when she was alone, thinking it was too dangerous, but what was the harm in doing a favor for a little old lady like this? Andrea pulled up a little way down the road, and the lady, holding a big shopping bag, hurried over to climb in the door which Andrea had opened for her.

      When she did get in, Andrea could see that she was not, in fact, so little. Broad and fat, the old lady had some difficulty climbing in through the car door, with her big bag, and when she had got in, she more than filled the seat next to Andrea. She wore a long, shabby old dress, and she had a yellow hat pulled down low over her eyes. Panting noisily from her effort, she pushed her big brown canvas shopping bag down onto the floor under her feet, and said in a voice which was almost a whisper, «Thank you dearie. I’m just going to Brockbourne.»

      «Do you live there?» asked Andrea, thinking that she had never seen
