与羊有关的习语
“sheep”在英语里指“绵羊”，“a grass-eating farm animal that is kept for its wool and its meat”；英文的sheep具有汉语“羊”的“善”与“羞”，
“goat”是指“山羊”,“an animal a little like a sheep that can climb steep hills and rocks”。goat富含贬义：act the goat（行为愚蠢）、old goat（老色鬼）。
所以，生肖“羊”应该选择“sheep”译名。
Separate the sheep from the goats 区分绵羊和山羊→辨别好人坏人（Divide things in two groups, those things that have value and those things that are less valuable / worthless）
I had rather be a tick in a sheep than such a valiant ignorance. 我宁愿做羊身上的虱子，不愿做这种没有头脑的勇士。
