中文原文：

馬鞍是放在馬背上供人騎的器具。

錯誤譯文：

A saddle is a utensil put on horseback for a person to ride on.

正確譯文：

A saddle is a seat put on horseback for a person to ride on.

翻譯加油站：

問題出在“器具”二字。馬鞍實際上是個坐位，不妨將utensil改為seat。utensil經常用在cooking utensil(烹飪用具), kitchen utensil(廚房器具)等與“吃”有關的搭配中，與坐位相聯系是不妥的。

漢語成語“工欲善其事，必先利其器”，可以譯為 A workman who intends to do a good job must first sharpen his tools. 英語有句意境類似的諺語：A bad workman quarrels with his tools. 其字面意思是：“笨拙的工匠干不好活賴工具不好使”。不妨簡單譯為：人笨賴刀鈍。
