请采纳为答案

Call on和call at的意思一样,都是"拜访""访问",但call on后接表示人的名词或代词,call at 后接表示地点或场所的词语.

I called on the Smiths yesterday.

我昨天拜访了史密斯一家人.

I called at the Smith's yesterday.

我昨天去了史密斯家.

I called on the doctor yesterday.

我昨天去拜访了医生.

I called at the doctor's yesterday.

我昨天去了医务室.

另外,call on还可以"号召",后面往往接动词不定式作宾语补主语.

如：

The headmaster called on the students to work harder.

校长号召学生们更努力地学习.
