贝督因为沙漠游牧部落，其部民强悍桀骜。

A nomadic desert people, Bedouin are hardy but unruly troops.

配上鹰头部的大眼、利喙，使这只鹰显得威风凛凛，桀骜雄猛的气势。

The big eyes, sharp beak and the attitude of the eagle make it appear awe-inspiring, wild and intractable.

遥望教学楼后的四棵老银杏，黄叶缤纷一地的灿烂，傲然的是桀骜苍劲的枝干。

Looking to the teaching building of the four old ginkgo, a land of colorful bright yellow leaves, proudly the Jieao vigorous branches.
