问题 That______out to me at the very beginning.

选项 A、ought to be pointed
B、ought to point
C、ought to have been pointed
D、ought to have pointed

答案C

解析 ought to意为“应当”,和动词不定式的一般时连用,表示劝某人做某事,或告诉某人有责任做某事,在这种情况下,不定式的动作尚未发生,例如:You oughtto be more careful.你应该更小心一些。此外,ought to跟动词不定式的完成时连用,用来谈论过去,表示“本来应该做某事却没有做”,含有责备之意,例如:You oughtto have finished the work yesterday.你昨天就该完成这项工作。at the very beginning一般作过去时间状语,因此ought to后面应用不定式的完成时,故A和D应予以排除。point out和that具有逻辑上的动宾关系,因此ought to后的动词不定式要用被动语态,所以只有C为正确答案。
