know about/know of

know about 与 know of 在意义上没有明显的差别,可以把它们看作是同义词。例如,EED 就是这么处理的:“If you know of something or know about it, you have heard about it.”

1. I don't know Mr. Smith but I know of [about] him. (Palmer) 我不认识史密斯先生，但我听说过他。

2. I know of the town but I've never been there. (MD) 我听说过这个城市,但我从未去过那里。

3. I knew about [of] it long ago. (Palmer) 我很久以前就听说过这件事。

4. He had to be buried and I knew of no relatives. (Ralph Ellison) 他必须埋葬,但我听说他没有亲属。

5. I didn't know about it until you told me. (HDCU) 在你没有告诉我之前,我从未听说过这件事。

6. ‘The head of Opus Dei?’ Of course I know of him. (Dan Brown, The Da Vinci Code)

“是天主事工会主教吗？”我当然听说过他。（《达·芬奇密码》）
