单选题 It is highly desirable that a new dean ______ for this department.
A. be appointed B. appoint
C. will be appointed D. is appointed

【正确答案】 A
【答案解析】[解析] 在It is highly desirable that...句型中,that引导的是主语从句,从句谓语动词要使用原形或者“should+动词原形”,因而,C项和D项不合适。又因为appoint和a new dean是逻辑动宾关系,所以从句谓语要使用被动语态,故只有A项正确。需要注意的是,与essential,imperative,possible,anxious,vital,keen,better,advisable,preferable,appropriate,desirable,eager,insistent,natural,proper,important,necessary,urgent等形容词相关的名词性从句中,谓语要使用动词原形或“should+动词原形”,例如:What is vital is that the right to vote be given to every adult. 每一个成年人都应该被赋予选举权是至关重要的。
