参考答案

正确答案：C
解析：本题是事实信息题，主要考查考生抓住第五段重要信息和细节的能力。题目问：当一只狐狸被一群鹅追赶时，它会有什么样的行为?根据原文“The great Canada Geese will even follow a fox overland in a close phalanx，and I have never known a fox in this situation try to catch one of his tormentors．With ears laid back and a disgusted expression on his face，he glances back over his shoulder at the trumpeting flock and trots slowly—so as not to lose face—away from them”，我们知道，当大群鹅追赶狐狸时，狐狸会为了保存面子，慢慢地走开，并不会马上逃离。因此该题选C。选项A(狐狸会攻击鹅群)是错误的，选项B(狐狸会立即逃走)不正确，选项D(狐狸停下来注视鹅群)也不正确。
