I worked the whole day for him这里为什么要用the

I worked the whole day for him这里为什么要用the I worked the whole day for him.翻译下 英语简单语法.I saw him heading for the river just now.这里为什么用him?什么 He has worked for a whole day After working for the whole day.he____tired. the whole day加介词for？ the whole day前有没有for the girl told us the whole thing in an excited voice.为什么这里要用 I spent the whole day _____ shopping. 这里的for the day I kept my word to visit him the next day为什么要用过去时态啊 the whole day和for the whole day有何不同?
