Each group will have a representative. In Engpsh, this can be translated as "each group will have a representative" or "each group will have someone to represent them." The term "representative" comes from the Latin word "representare," which means "to present again" or "to exhibit." Here are some example sentences in Engpsh and their Chinese translations:

Each group will have a representative to speak on their behalf at the meeting. (每组在会议上都会有一个代表来代表他们。)
The representative will be responsible for communicating the needs and concerns of their group to the larger organization. (代表负责将小组的需求和关切告诉更大的组织。)
The representative must be chosen carefully to ensure that they can accurately represent the views of their group. (必须仔细选择代表，以确保他们能够准确地代表小组的观点。)
