　　Section B

　　Passage One

　　The dog has often been an unselfish friend to man. It is always grateful to its master. It helps man in many ways. Certain breeds of dogs are used in criminal investigations. They are trained to sniff out drugs and bombs. They help police to catch criminals.

　　The dogs that help in criminal investigations are trained at a school called the Military Dog Studies Branch of the U.S. Air Force in Lackland, Texas. The dogs to be trained are selected by an air force team. This team visits large cities across the country to buy the dogs. They may buy dogs from private citizens for up to $750 each. Some citizens freely give their dogs. The dogs selected must be healthy, brave and aggressive. They must be able to fight back if they are attacked. The dogs chosen are between the ages of one and three. They are given a medical examination when they arrive at the school. Their physical examination includes X-rays and heart tests. The trainee dogs undergo the first stage of training when they arrive in Lackland. This is an 11-week course for patrol duty. After this course, the best dogs are selected to go on another 9-weekcourse. They learn drug-sniffing or bomb-sniffing. After this course, the dogs are ready for their jobs in the cities or on air force bases.

　　The training given to a drug-sniffing dog is different from that given to a bomb-sniffing dog. A drug-sniffing dog is trained to scratch and dig for the drugs when he sniffs them. A bomb-sniffing dog sits down when he finds a bomb.

　　That is the alert for hidden explosives.

　　Questions 26 to 28 are based on the passage you have just heard.

　　26. How are the dogs obtained for training?

　　27. What is the first stage of training for the dogs?

　　28. What do dogs learn during the 9-week training?

　　Passage Two

　　From this lookout we enjoy one of the most spectacular views of San Francisco. As you can see, the city rests on a series of hills varying in altitude from sea level to 938 feet. The first permanent settlement was made at this site in 1776. For 13 years the village had fewer than one hundred inhabitants. But in 1848, with the discovery of gold, the population grew to ten thousand. The same year the name was changed from Yerba Buea to San Francisco.

　　By 1862 telegraph communications linked San Francisco with eastern cities, and by 1869 the first transcontinental railroad connected the Pacific coast with the Atlantic seaboard. Today San Francisco has a population of almost three million. It is the financial center of the west, and serves as the terminus for trans-Pacific steamship lines and air traffic.

　　The port of San Francisco, which is almost 18 miles long with 42 piers, handles between five and six million tons of cargo annually.

　　And now, if you will look to your right, you should just be able to see the east section of the Golden Gate Bridge. The bridge, which is more than one mile long, spans the harbor from San Francisco to Marin County and the Red Wood Highway. It was completed in 1937 at a cost of 32 million dollars and is still one of the largest suspension bridges in the world.

　　Questions 29 to 31 are based on the passage you have just heard.

　　29. According to the tour guide, what happened in 1848?

　　30. What is the population of San Francisco today?

　　31. How much did it take to complete the construction of the Golden Gate Bridge?

　　Passage Three For good or bad, computers are now part of our daily lives. With the price of a small home computer now being lower, experts predict that before long all schools and businesses and most families in the rich parts of the world will own a computer of some kind. Among the general public, computers arouse strong feelings-people either love them or hate them.

　　The computer lovers talk about how useful computers can be in business, in education and in the home-apart from all the games, you can do your accounts on them, use them to control your central heating, and in some places even do your shopping with them. Computers, they say, will also bring some leisure, as more and more unpleasant jobs are taken over by computerized robots.

　　The haters, on the other hand, argue that computers bring not leisure but unemployment. They worry, too, that people who spend all their time talking to computers will forget how to talk to each other. And anyway, they ask, whats wrong with going shopping and learning languages in classroom with real teachers? But their biggest fear is that computers may eventually take over human beings altogether.

　　Questions 32 to 35 are based on the passage you have just heard.

　　32. What does this passage mainly talk about?

　　33, According to the passage, what is not mentioned about computers?

　　34. What is the biggest fear of the computer haters?

　　35. Whats the speakers attitude to computers?
