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( ).

1. 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!

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.

5. Passage 20 Clifford Stoll ran a computer system in Berkelely， California. As a system administrator， he kept a close eye on the records. One day， Stoll found something strange in the payment record. There was a 75 cents mistake. One of the thousands of users had used the system for 75 worth of time and not paid for it. It might sound like very little money to worry about. But that 75 cents was the first clue Stoll had to a much bigger problem — that a hacker(黑客)had broken into Stoll‘s computer system. Who was it? Stoll spent the next year trying to find out. During that time the hacker used the system in Berkelely as a starting point to break into military computer systems all over the United States. Stoll had to keep track of the hacker‘s activities on the computer without the hacker‘s knowing someone was watching him. Stoll even made up huge files of false information so the hacker would have lots to read. When the hacker spent long time reading， the telephone company was able to trace the lines.
