Question

in charge of in the charge of区别

Answer 1

in charge of和in the charge of都是短语介词，其后都接名词或代词作宾语。

in charge of主动，主语往往是人
in the charge of 被动，主语一般是物
in charge of“管理，看管”
in the charge of “被... 管理，在...管理之下”
同时in the charge of 也可用in one's charge形式。
例如：
An experienced worker is in charge of the project.
一位经验丰富的工人负责这项工程。
The documents are in the charge of Comrade Lee.
文件由李同志保管。
另外注意in charge:
in charge介词短语，用作表语或后置定语，意为“负责，看管”。
句子的主语一般应是表示人的名词或代词，charge可以有形容词修饰。
例如：
John was in complete charge while the manager was on holiday.
约翰在经理度假时负全责。
The person in overall charge was Jones.
总负责人是琼斯。
