句子：“蚁族”是对高校毕业生低收入聚居群体的形象比喻。

　　误译：Ant family is a vivid metaphor of the groups of low-income college graduates who settle in a compact community。

　　正译：Ant tribe is a vivid metaphor of the groups of low-income college graduates who settle in a compact community。

　　解释：“蚁族”有ant family, ant clan, ant tribe和 ant community 等译法。family 的第一个意思是核心家庭，第二个意思是外延家庭，第三个意思是“家族”，第四个意思是a group of related animals and plants，动物分类译为“科”

　　例如：Tigers belong to the cat family. (虎属于猫科。) 这里的“蚁族”不是有血缘关系的同一家庭或家族，也不是一种昆虫分类的名称，译为ant family是不合适的。Clan 有a group of people who are connected because of a particular thing的意思。

　　将“蚁族”译为ant clan是可以接受的。例如：1. 这些低收入高校毕业生与蚂蚁有相同特点，例如弱小、群居和勤奋，因此被称为“蚁族”。

　　As these low-income university graduates have the same characteristics as ants, for example, they are weak, gregarious and hard-working, they are called "ant clan"。

　　Tribe有a group of people, esp. of one profession的意思。将“蚁族”译为ant tribe也是可以接受的。

　　例如：2.“蚁族”是继农民、农民工和下岗职工之后我国的第四个弱势群体。

　　Next to farmers, rural migrant workers and laid-off workers, ant tribe is the fourth disadvantaged group in our country。

　　Community有a group of people ho share the same religion, race, job, etc. 的意思。将“蚁族”译为ant community也是可以接受的。
