agree可做及物动词，直接带宾语。所以你的句子是对的。 但是日常趋向用agree +介词on sth, with sb, to(作介词)sth. 所以最好是：afer a short time, the program was agreed on (to).还有： agree 后面接that引导的句子或不定式时，不用介词with或on. 例如： It is agreed that we hold a meeting every Monday.We agree that the plan is a good one.We agreed to start early. agree with和agree about不可用于被动语态是因为他们的主语是人或组织。例如：We agree with him and agree about his ideas.
