be concerned with

原文:CAMBRIDGE IELTS 3

"be concerned with" =>與...有關
所以底下的例句可以重組為
"one is concerned with the particular individual  in the analysis of any situation is usually given the name of focal person."

可以解釋成
"和the particular individual 有關的那個人被稱為focal person"
那個 particular individual? =>情境分析中的那個特定individual.
而the particular individual可以被解釋成"受到關注的個體"
所以這句可以解釋成
在做情境分析時,特別受到關注的個體稱為focal person


Any individual in any situation occupies a role in relation to other people. The particular individual with whom one is concerned in the analysis of any situation is usually given the name of focal person. He has the focal role and can be regarded as sitting in the middle of a group of people, with whom he interacts in some way in that situation. This group of people is called his role set.
