Jim has been over his homework and he is free now这句可以等于下面那句吗?帮我挑挑刺,

over 副词,结束,用法是：
sth is over （be有各种形式）：.完了、结束了,一般后面不跟宾语.
如,The match is over.
比赛结束了.
Jim has been over his homework 最好改为：
"Jim‘s homework has been over",and he is free now
=Jim has finished doing his homework already.He is free now
希望不要介意挑刺,）
