The increase in international business and in foreign investment has created a need for executives with knowledge of foreign language and skills in cross-cultural communication. 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. The American negotiator’s role became that of and impersonal purveyor of information and cash, the image that succeeds only in underming the negotiation.          

In studies of American negotiators abroad, several traits have been identified that may serve to confirm that stereotypical perception, while subverting the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on that part of Amarican negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator.         

Clearly, perceptions and differences in values affect the outcomes of negotiation and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding.

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.  

Question 43: The upbringing of highly intelligent children requires________.

Harvard University, today recognized as part of the top echelon of the world's universities, came from very inauspicious and humble beginning.

This oldest of American universities was founded in 1636, just sixteen years after the Pilgrims landed at Plymouth. Included in the Puritan emigrants to the Massachusetts colony during this period were more than 100 graduates of England's prestigious Oxford and Cambridge universities, and these universities graduates in the New Word were determined that their sons would have the same educational opportunities that they themselves had had. Because of this support in the colony for an institution of higher learning, the General Court of Massachusetts appropriated 400 pounds for a college in October of 1636 and early the following year decided on a parcel of land for the school; this land was in an area called Newetowne, which was later renamed Cambridge after its English cousin and is the site of the present-day university.

When a young minister named John Harvard, who came from the neighboring town of Charlestowne, died from tuberculosis in 1638, he willed half of his estate of 1,700 pounds to the fledgling college. In spite of the fact that only half of the bequest was actually paid, the General Court named the college after the minister in appreciation for what he had done. The amount of the bequest may not have been large, particularly by today's standard, but it was more than the General Court had found it necessary to appropriate in order to open the college.

Henry Dunster was appointed the first president of Harvard in 1640, and it should be noted that in addition to serving as president, he was also the entire faculty, with an entering freshmen class of four students. Although the staff did expand somewhat, for the first century of its existence the entire teaching staff consisted of the president and three or four tutors.

Question: The word "somewhat" in the last paragraph could best be replaced by _______.

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:

Milpa Alta is a region of twelve villages and towns to the south of Mexico City. In Milpa Alta, traditions are still very important and one of the most famous traditional events is a community meal. It takes place every Christmas and is called La Rejunta. More than a meal, it’s a feast, where about sixty thousand tamales and fifteen thousand litres of hot chocolate are made and consumed. Tamales are made from corn. They are typical of the region: the name Milpa Alta means "High cornfield". The feast is offered to the people who go on the long walk to El Señor de Chalma about 80 kilometers away. It’s an important event on the religious calendar for local people and as many as 20,000 people take part.

The planning and organisation of La Rejunta takes the whole year. Every year, different people are given the job of majordomo, which means they’re responsible for organising the meal. There’s a waiting list for the opportunity to do this and currently the next available year is 2046. This year’s majordomos are Virginia Meza Torres and her husband Fermín Lara Jiménez, who put their names on the list 14 years ago.

One year before the meal, men go to the forest and collect wood that they store near the home of the majordomo. It has to be dry when it’s used to make the cooking fires. Local farmers grow most of the corn, meat and vegetables that are needed as ingredients. In the week before the feast, hundreds of volunteers arrive to help with the preparation and the cooking. No instant or ready-made foods are allowed. Amazingly, everyone seems to know what they have to do. On the day of the feast, the majordomos and others have stayed up all night cooking. Fermin is in charge of the numbers–making sure there are enough tamales for everyone.

For the people of Milpa Alta, eating together is one of their most important traditions. One woman, Josefina García Jiménez, explains that sitting together at the table is like a glue that keeps people together. "It feels like I am passing down a tradition, and when they are adults, they will remember what I have done. Here we have time to cook, time to think about the ingredients, time to show our kids through cooking that we love them." The time that everybody stays at the table after the meal has finished is just as important as the food.

They talk, tell stories and laugh together. At Christmas, La Rejunta is a giant version of a family meal.  

Question 50: According to the last paragraph, the important thing about family meals is _____________.
