问题 Although buses are ______ to depart at a certain hour, they are often late.

选项 A、scheduled
B、obligated
C、requested
D、loaded

答案A

解析词汇题，考查动词辨析。schedule作名词意为“时刻表”，作动词意为“安排时间”；obligate意为“使有义务”，常用于被动语态，如：He felt obligated to help the girl．(他感觉有义务帮助这个女孩儿。)；request意为“要求”，其宾语从句中常用虚拟语气，如：She requested the door be left open．(她要求开着门。)；load意为“装载”，如：load a truck(装车)。
