Questions 61 to 65 are based on the following passage:
In many countries there is a fixed charge for personal services. A certain percentage may be added to the bill at a hotel or restaurant “for the service”. In other places the customer may be ex?pected to give a tip, or a small amount of money, as a sign of appreciation whenever services are performed. In the United States there is no consistent practice with regard to tipping. The practice is more common in a large city than in a small town. A Native American may often be in doubt about when and how much to tip when he is in a city that is strange to him. In general, however, a tip is expected by the porter who carries you baggage, by taxi drivers (except, per?haps, in small towns), and by those who serve you in hotels and restaurants.
When you pick up your incoming luggage at an airport, you may tip the man who takes it to the taxi or airport bus. He usually expects 35 cents a bag for his service. In some cities the taxi that takes you to your hotel may have one meter that shows the cost of the trip and another that shows a fixed charge, usually about 20 cents, for “extra”. In some cities the taxi driver may ex?pect a tip in addition to the “extra”, especially if he carries your suitcase. If no “extra” is charged, a tip is usually given. Hotels usually do not have a service charge, though there are places where one is added. It is customary, however, to give something to the porter who carries your suitcases and shows you to your room. If in doubt, 25 cents for each bag he carries is satis?factory. In a restaurant you generally leave about 15 percent of the bill in small change on the table as a tip for the person who has served you. A service charge is generally not included except in some of the larger, more expensive places. If the order is small—a cup of coffee at a lunch counter, or something of the sort—a tip is not usually expected.

Questions 66 to 70 are based on the following passage:
People are fascinated by robots. Some of them look like mechanical dolls to play with. Most of them look like other machines of today’s technology.
One of the advantages of robots is that they can work in situations that are dangerous or harmful for human workers. For example, the continuous smell of paint has a harmful effect on painters, but it doesn’t bother a robot. Robots can work in nuclear power plants and in undersea research stations that might be dangerous for humans.
There are robots in the plastics industry and in chemical industry and industrial equipment industries. One of the most common uses of robots is in automobile factories. They can do the heavy, unpleasant, or dangerous work. For example, a computer programmer writes a program that tells how much paint to use, how thick it must be, and the size of the car body. The robot does not waste any time or movements. It never becomes bored. It doesn't need a coffee break. It lasts 20 to 25 years.
Today’s robots are simple-minded compared with the ones of the future. Researchers are now working on the sixth generation. These new robots will be able to take information from the environment. They will be able to see, using television camera for eyes. They will be able to touch and hear. Some computers can already understand a limited vocabulary. Researchers are trying to develop ones that can understand human speech. They will be able to understand voice commands and then respond.
The new robots will be able to move in more ways. They will have several arms, each will several fingers. The robot will be able to operate these arms and fingers by itself. It will be able to make complex decisions in a working environment.

Questions 71 to 75 are based on the following passage:
In some urban centers, workaholism is so common that people do not consider it unusual. They accept the lifestyle as normal. Government workers in Washington D. C., for example, fre?quently work sixty to seventy hours a week. They don’t do this because they have to; they do it because they want to.
Workaholism can be a serious problem. Because true workaholics would rather work than do anything else, they probably don’t know how to relax; that is, they might not enjoy movies, sports, or other types of entertainment. Most of all, they hate to sit and do nothing. The lives of workaholics are usually stressful, and this tension and worry can cause health problems such as heart attacks or stomach disorders. In addition, typical workaholics don’t pay much attention to their families. They spend little time with their children, and their marriages may end in divorce.
Is workaholism always dangerous? Perhaps not. There are, certainly, people who work well under stress. Some studies show that many workaholics have great energy and interest in life. Their work is so pleasurable that they are actually very happy. For most workaholics, work and entertainment are the same thing. Their jobs provide them with a challenge; this keeps them busy and creative.
Why do workaholics enjoy their jobs so much? There are several advantages to work. Of course, it provides people with paychecks, and this is important. But it offers more than financial security. It provides people with self-confidence; they have a feeling of satisfaction when they've produced a challenging piece of work and are able to say, “I made that.” Psychologists claim that work gives people an identity, through participation in work, they get a sense of self and individ?ualism. In addition, most jobs provide people with a socially acceptable way to meet others.
