(单选题)

Working too hard may turned out to be helpful if you ______.

A.keep a good relationship with your parents

B.pay close attention to your physical health

C.work overtime for a one-week research project

D.stay up late for a 6-month building project

参考答案：C

参考解析：

细节理解题。A项意为“和父母保持好的关系”；B项意为“紧密关注自己的身体健康”；C项意为“在一项一周的调查项目中加班”；D项意为“在一项6个月的建筑项目中熬夜”。根据第二段第九句“This is true especially if you allow yourself to indulge this bad habit for only the period of a short project.”可知，当你允许自己在一个短期项目期间放纵的话，过于努力工作可能会成为一种好的习惯，因此C项正确，而A项、B项和D项皆不符合。故选C。
