Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions:

 Telecommuting is some form of computer communication between employees’ homes and offices. For employees whose job involve sitting at a terminal or word processor entering data or typing reports, the location of the computer is of no consequence. If the machine can communicate over telephone lines, when the work is completed, employees can dial the office computer and transmit the material to their employers. A recent survey in USA Today estimates that there are approximately 8,7 million telecommuters. But although the numbers are rising annually, the trend does not appear to be as significant as predicted when Business Week published “The Portable Executive” as its cover story a few years ago. Why hasn’t telecommuting become more popular?

 Clearly, change simply takes time. But in addition, there has been active resistance on the part of many managers. These executives claim that supervising the telecommuters in a large work force scattered across the country would be too difficult, or, at least, systems for managing them are not yet developed, thereby complicating the manager’s responsibilities.

 It is also true that employees who are given the option of telecommuting are reluctant to accept the opportunity. Most people feel that they need regular interaction with a group, and many are concerned that they will not have the same consideration for advancement if they are not more visible in the office setting. Some people feel that even when a space in their homes is set aside as a work area, they never really get away from the office.

Question: The word “them” in the second paragraph refers to_______

Mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions:

Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level in negotiation in an international arena as have their foreign counterparts.          

Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. Involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of negotiation.          

In many international negotiations business abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that Americans represents a large multimillion–dollar corporation that can afford to pay the price without bargaining further.

Question: According to the passage, how can the business persons improve their negotiation skills?         

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50:

Psychologist have debated a long time about whether a child’s upbringing can give it the ability to do outstandingly well. Some think that it is impossible to develop genius and say that it is simply something a person is born with. Others, however , argue that the potential for great achievement can be develop. The truth lies somewhere between these two extremes. It seems very obvious that being born with the right qualities from gifted parents will increase a child’s ability to do well. However, this ability will be fully realized only with the right upbringing and opportunities. As one psychologist says, “ To have a fast car, you need both a good engine and fuel.’’ Scientists have recently assessed intelligence, achievement, and ability in 50 sets of identical twins that were separated shortly birth and brought up by different parents. They found that achievement was based on intelligence, and later influenced by the child’s environment. One case involving very intelligent twins was quoted. One of the twins received a normal upbringing, and performed well. The other twin, however, was brought up by extremely supportive parents and given every possible opportunity to develop its abilities. That twin, thought starting out with the same degree of intelligence as the other, performed even better. This case reflects the general principle of intelligence and ability. The more favorable the environment, the more a child’s intelligence and ability are developed. However, there is no link between intelligence and socioeconomic level of a child’s family. In other words, it does not matter how poor or how rich a family is , as this does not affect the intelligence. Gifted people can not be created by supportive parents, but they can be developed by them. One professor of music said that outstanding musicians usually started two or three years earlier than ordinary performers, often because their parents had recognized their ability. These musicians then needed at least ten years’ hard work and training in order to reach the level they were capable of attaining. People who want to have very gifted children are given the following advice: Marry an intelligent person. Allow children to follow their own interests rather than the interests of the parents. Start a child’s education early but avoid pushing the child too hard. Encourage children to play; for example, playing with musical instrument is essential for a child who wants to become an outstanding musician.
