15分请教个英语问题
but this did not prove to be a problem.
上面这个句子助动词did可以用was代替么?
变成but this was not proved to be a problem.
如果不可以请问为什么?最好能够分解下原句成分,谢谢~

这句话中的did不能改为was.这主要是要理解prove的用法.这个单词主要有两种基本用法.
1,可以作为实意动词并且是及物动词,意为：证实,证明,如prove +that从句,此时是可以用被动语态.
2,可以作为连系动词 .因为连系动词在语法上没用被动语态,故翻译为：证明是,被发现是,显示出是.此时,它的用法是：prove to be sth.
因为but this did not prove to be a problem.这句话中已经用了prove to be 句型,所以prove 是作为连系动词用,不能用被动语态.故不能改为was.
原句成分分析:but是转折连词,连接上一个句子和这个句子；this 是这个句子的主语,did not prove to be 是谓语,a problem是to be 的表语,也可称为补语.
这个是基础问题,朋友,多多加油.
