一类是：译语与原语存在对应的关系，使动物形象再现成为可能。根据两种语言在意义、形象或风格上的相似性，翻译时可采用同值、近值互借法，以再现原语形象。例如：

    1．What a dull speech! He's merely parroting what many others have said.多么单调乏味的讲话！他不过是鹦鹉学舌，重复许多人说过的话而已。

    2． A wolf in sheep's clothing披着羊皮的狼3． One swallow does not make a summer.孤燕不成夏。

    4． He is as sly as a fox. You've got to watch him.他狡猾得像个狐狸。对他你可要当心点儿。

    5． You stupid ass! How could you do a thing like that?你这头蠢驴！怎么会干出那种事儿来？

    6． The children were as busy as bees, making preparations for the festival.孩子们准备过节忙得像蜜蜂一样。

    另一类是：同一动物形象在原语和译语中的语用意义相去甚远，甚至完全相悖。因此，在翻译过程中就出现了动物形象名称的转换。这种动物形象的转换可以是一种动物形象转换为另一种动物形象。例如：

    1． Talk horse.吹牛。（horse译为“牛”）2． Ass in a lion's skin.狐假虎威。（ass译为“狐”，lion译为“虎”）3． Black sheep.害群之马。（sheep译为“马”）4． Lock the stable door after the horse is stolen.亡羊补牢。（horse译为“羊”）5． Cast pearls before swine.对牛弹琴。（swine译为“牛”）6． When the cat is away, the mice will play.山中无老虎，猴子称大王。（cat译为“老虎”，mice译为“猴子”）7． As hungry as a bear.饿得像狼。（bear译为“狼”）8． Kill the goose that lays the golden eggs.杀鸡取卵。（goose译为“鸡”）9． As timid as a hare.胆小如鼠。（hare充为“鼠”）10．Neither fish, flesh nor fowl.非驴非马。（fish, flesh译为“驴”owl译为“马”）11．Break a fly upon the wheel.杀鸡用牛刀。（fly译为“鸡”）
