請采納為答案
Call on和call at的意思一樣,都是"拜訪""訪問",但call on后接表示人的名詞或代詞,call at 后接表示地點或場所的詞語.
I called on the Smiths yesterday.
我昨天拜訪了史密斯一家人.
I called at the Smith's yesterday.
我昨天去了史密斯家.
I called on the doctor yesterday.
我昨天去拜訪了醫(yī)生.
I called at the doctor's yesterday.
我昨天去了醫(yī)務室.
另外,call on還可以"號召",后面往往接動詞不定式作賓語補主語.
如：
The headmaster called on the students to work harder.
校長號召學生們更努力地學習.
