单选题 That ______ out to me at the very beginning.
A. ought to be pointed B. ought to point
C. ought to have been pointed D. ought to have pointed

【正确答案】 C
【答案解析】[解析] ought to意为“应当”,和动词不定式的一般形式连用,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 ought to be more careful. 你应该更小心一些。此外,ought to跟动词不定式的完成形式连用,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 ought to 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项和D项应予以排除。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形式,所以只有C项为正确答案。
