单选题 When he started wearing a pedometer and didn't accumulate 10,000 steps by the end of the day, he was______himself and went out and walked until he had.
A. blamed by B. regulated by C. ticked off D. prompted by

【正确答案】 C

【答案解析】句意：他开始带上计步器，如果一天快结束的时候还没有走够1000步，他会自己生闷气然后出门把剩下的步数走完。be blamed by oneself“指责自己”，程度过深不符合语意。be ticked off by oneself自己生自己的气。而be regulated by oneself和be prompted by oneself这两种用法不存在。所以答案选c。
