本题考查对句子中形容词含义的理解，特别是“challenging”和“rewarding”的语境意义。关键在于理解这两个形容词的常见用法，以及如何通过并列结构推断整体句意。“challenging”表示“有挑战性、困难”，“rewarding”表示“值得的、有回报的”，两者通过“but”连接，形成对比但互补的关系。

选项分析

选项A

“it's not a good job”
错误。虽然“challenging”说明工作困难，但“rewarding”强调工作有回报，整体并非否定评价。

选项B

“the job will bring you a lot of money”
错误。“rewarding”通常指“精神上的满足”或“非金钱回报**，而非“大量金钱”。

选项C

“it's a difficult job, and the pay is low”
错误。原句未提及“工资低”，“rewarding”与“pay”无关。

选项D

“the job is difficult, but it is worth doing”
正确。“challenging”对应“difficult”，“rewarding”对应“worth doing”，完整体现原句的对比与肯定。
