问题 ______ as a psychologist with all kinds of people, I’ve learned that successful people aren’t necessarily the ones with the greatest natural talent.

选项 A、Worked
B、Having worked
C、To work
D、Being worked

答案B

解析 非谓语动词用法。分析全句发现主句前面为原因状语从句,动词work和主句主语之间为主动关系,因此用现在分词。同时考虑到两个动词、work和learn之间有一个时间上的先后,应采用完成时。故B项Having worked正确。
