2. Passage 2 Man has always wanted to fly. Some of the greatest men in history had thought about the problem. One of them， for example， was the great Italian artist， Leonardo Da Vinci. In the 16th century he made designs for machines that would fly， but they were never built. Throughout history， other less famous men had wanted to fly. An example was a man in England 800 years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into air from a tall building. He did not fly very far. Instead， he fell to the ground and broke every bone of his body and rested in peace. The first real step took place in France， in 1783. Two brothers， the Montgolfiers， made a very large ―hot air balloon‖. They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year， the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted eight minutes and that the animals landed safely. Two months later， two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about. Eight hundred years ago an Englishman( ).

4. Passage 12 More and more people like bicycling and it is no surprise. It is fun， healthy and good for the environment. Maybe that‘s why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere， and there is no oil cost! Get on a bicycle and ride around your neighborhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit from the enjoyable exercise without polluting the environment. You don‘t even have to ride all the way. Folding bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travelers. Health Benefits of Bicycling: It helps to prevent heart diseases. It helps to control your weight. A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year. It can improve your mood.

3. Passage 19 Throughout her working life， a ship — like a motorcar — must be serviced regularly if she is to remain efficient. After a period at sea she must be overall checked and any necessary repairs must be made. There are also instances when a ship must be converted from being one kind of carrier to another. Most of today‘s oil， for example， is carried by huge super-tankers. The smaller tankers， many of which are still in good condition， can be converted into bulk carriers(散货船) for the transport of sugar， coal or ore. Conversion or repair work is carried out in a dry dock， a huge hole cut into the ground and lined with concrete. At one end are large gates separating the dock from the river or sea. When these gates are opened， water pours into the dock and fills it. A ship can then enter the dock， where it is carefully fastened in an upright position. When the ship is positioned inside the dock， the gates are closed and the water is pumped out. The vessel slowly settles on to wooden blocks. Wooden supporters are put in position between the ship and the sides of the dock to prevent her from rolling over. Great care is taken to make sure that the ship rests evenly on the keel(龙骨)blocks to prevent damage being done. As soon as the ship is firmly positioned， repair or conversion work can begin on her body or superstructure. We can infer that a dry dock( ).
