Teaching is challenging but rewarding work.

教書(當教師)是富挑戰性但有滿足感的工作。

留意這些英文字使用跟以中文字譯英文的用詞不是同等的。
(如用中文想講滿足感你可能只會想到satisfy但這享受上的滿足不等工作上的滿足，而rewarding的意思亦不是指有好收入報酬和贘金那種reward的意思。)

Teaching work is challenging but rewarding.

Teaching is challenging but rewarding work

Teaching is rewarding but challenging.
