call on和call at有什么区别

Question

如题所述

Answer 1

　　Call on和call at的意思一样，都是"拜访""访问"，call on=call upon；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。试比较：
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。
