He bought a new book____ (tell of)someone's successful experiences.

问题描述:

He bought a new book____ (tell of)someone's successful experiences.
变telling of 还是told of
我觉得把句子补充完整是
he bought a new book that told of someone's successful experiences.
因为THAT后面那个从句要有一个动词嘛
但是凭感觉又觉得是telling of 到底是哪个?

telling of
