     When former American President Bill Clinton travelled to South Korea to visit President Kim Young Sam,

he repeatedly referred to the Korean president's wife as Mrs. Kim. By mistake, President Clinton's advisers

thought that Koreans have the same naming customs as the Japanese. Clinton had not been told that, in Korea,

wives keep their family names. President Kim Young Sam's wife was named Sohn Myong Suk. Therefore,

she should be addressed (称谓) as Mrs. Sohn.

     President Clinton arrived in Korea directly after leaving Japan and had not changed his culture gears. His

failure to follow Korean customs gave the impression that Korea was not as important to him as Japan.

     In addition to Koreans, some Asian husbands and wives do not share the same family names. This practice

often puzzles (使困惑) English-speaking teachers when talking with a pupil's parents. They become puzzled

about the student's correct last name. Placing the family name first is common among a number of Asian

cultures.

     Mexican naming customs are different as well. When a woman marries, she keeps her family name and

adds her husband's name after the word de (of). This affects (影响) how they fill in forms in the United States.

When requested to fill in a middle name, they generally write the father's family name. But Mexicans are

addressed by the family name of the mother. This often causes puzzlement.

     Here are a few ways to deal with such difficult situations: don't always think that a married woman uses

her husband's last name. Remember that in many Asian cultures, the order of first and last names is reversed

(颠倒), Ask which name a person would prefer to use. If the name is difficult to pronounce, admit it, and

ask the person to help you say it correctly.

A lot of us lose life’s tough battles by starting a frontal(正面的) attack — when a touch of humor might well enable us to win. Consider the case of a young friend of mine, who

36  a traffic jam on his way to work shortly   37  receiving an ultimatum(最后通牒) about being late for work. Although there was a good reason for Sam’s being late — serious illness at home — he decided that this by-now-familiar excuse wouldn’t   38  any longer. His supervisor(主管) was probably already pacing up and down preparing a dismissal

39  .

Yes, the boss was. When Sam entered the office at 9:35, it was as   40  as a locker room(更衣室)— everyone was hard at work. Sam’s supervisor   41  him. Suddenly, Sam forced a grin (露齿笑) and   42  out his hand. “How do you do!” he said. “I’m Sam Maynard. I’m    43  a job, which, I understand, became available just 35 minutes ago. Does the early bird get the worm?”

The room burst into   44  . The supervisor clamped off(忍住) a smile and walked back to his office. Sam Maynard had   45  his job — with the only tool that could win, a laugh.

Humor is a most effective, yet   46   ignored, means of handling the difficult situations in our lives. It can be used for patching up differences, apologizing, saying “no”, criticizing, getting the other fellow to do what you want   47  his losing face. For some jobs, it’s the only tool that can succeed. It is a way to discuss subjects so sensitive that serious dialogue may start a quarrel.
