以下3题请帮忙看一下正确答案.被动,现完,翻译
一共3题:
1.All these books need to be packed in to the boxes.
句里的need to be packed就是 need to be done的形式吧?主语是物,需要被做某事?
2A. The teacher was already in the classroom when I arrived.
2B. She had already left when I phoned.
2B能用现在完成时,为什么2A这句是用一般过去式was already ,而不是现在完成时been already ?2A能用现在完成时been already 吗?
3.他已经做完作业.以下翻译都对吗?
3a.He has finished his homework.
3b.He has done his homework.

1.All these books need to be packed in to the boxes.
句里的need to be packed是need to be done的形式
主语是All these books所有的这些书需要被整理到盒子里去
2A.The teacher was already in the classroom when I arrived.
2B.She had already left when I phoned.
2A这个形式也是现在完成时.加上been 只是被动态.首先left不能"被'离开.其次因为left是短暂性动词,不可以加延续性的
3.他已经做完作业.以下翻译都对吗?
3a.He has finished his homework.
3b.He has done his homework.
正确的!

是的.2B是过去完成时.2A2B都是复合句,或者说时间状语从句

The teacher was already in the classroom when I arrived。那么就是一般过去时?

1 need这里是谓语动词,这些书是物,不能主动做某事 ,只能是被。。。。处理
2 首先,2B用的不是现在完成时
其次,2A :当我到达时,老师已经在教室了,我 arrived是过去式,已经发生了 ,这个作为时间状语来看的话,当我过去某个时间到教室了的时候,老师已经在了,老师在这个动作肯定也是在过去那个时间之前就发生了,不能用现在完成时
3 都对
