An evacuee is a person sent away from a place because staying is dangerous — war, a fire, a flood, a chemical leak, a coming storm. The move is usually organised: a government, an army, or the police say “you must leave,” and people go to a safer town, a school hall, or another country for a time. The famous picture in British English is the Second World War, when city children were sent to the countryside; those children were evacuees, and many stories still use the word that way. Today news uses it for anyone taken out of a disaster zone. An evacuee is not automatically a refugee. A refugee has fled and often cannot safely go home, and may cross a border for a long stay; an evacuee is often meant to return when the danger has passed, and may only have moved to the next town. The word is a little formal — news and history more than playground talk — but it is the ordinary noun once you need to name the person, not just the action.

撤離者、被疏散的人（和「難民」不一樣：通常是被安排離開、並預期回去）
