fdkbaby

552.    Once the economic and social usefulness of the motor car was demonstrated and with its superiority to the horse being proved, much of the early hostility to it in rural regions disappeared.
(A) and with its superiority to the horse being
(B) and its superiority over the horse had been
(C) and its superiority to the horse
(D) its superiority over the horse
(E) with its superiority to the horse having been

参考答案C。

我的疑问是用superiority over可以吗？我查了一下字典，也有superiority over啊，而且和superiority to意思一样。

另外C中的proved为什么不是was proved？

请各位指教！

gemj

用superiority over是可以的。
proved是was proved的省略形式。因为前面was demonstrated中有WAS。

谢谢gemj,再问一句，两个不同的主语，不同的谓语动词，也可以这样省助动词吗？请指教。

gemj

可以呀，没问题。

多谢！

请问prove不是主动表示被动吗？？？

不是，GENJ说的很清楚了啊，
