单选题 Although punctual himself, the professor was quite used ______ ate for his lecture.

A、 to have students
B、 for students' being
C、 for students to be
D、 to students' being

【正确答案】 D

【答案解析】[解析] “be used to”作“习惯于”讲时，其中to为介词，后可跟动名词或动名词的复合结构(即“名词所有格+动名词”)。例如：He is used to bellowing at his children．他习惯对孩子大吼大叫。 He is not used to being spoken to like that。他不习惯别人用那种方式和他说话。
