(单选题)

Which of the following is the most suitable title for the article? ( )

A.three things you absolutely must do at work before vacation

B.three common workplace mistakes to avoid

C.how to make up for vacation deadlines

D.three things you must understand about having a vacation

参考答案：D

参考解析：

主旨题，根据首尾原则可知文章首段是对现象的描述，第二段最后引出主题，并且以小标题形式出现，所以结合第二段Avoid any vacation interruptions and disgruntled co-workers by doing these three things before you take off.可知这篇文章应当是给出的三个策略，选项C表述排除。A选项：在度假之前你工作中一定必须要做的三件事；B选项：三件常见的需要避免的职场错误，与文中的主体词不符，排除；D选项：关于休假你必须了解的三件事。结合选项AD可知选项A表述过于绝对。故本题正确答案选D。
