大全552(sec10-15)

15. 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.   C

(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

请牛牛解释下 选C的理由?

意思是: was demonstrated and  proved ??

还原以后应该变为: usefuless was demonstrated and its superiority was proved...  .

demostrated的对象是usefullness; proved的对象是superiority, and前后两个不同的主语可以被同一个助动词(was)跟吗?

比如: I was killed in my house and she (was可以省略??) killed  in her house.

另外:B选项有没有什么严重的错误??? had been 是否影响句子意思的表达?

查了查字典

只能

superior over sth

superiority to sth

还是不明白啊

摆脱摆脱牛牛来指点迷津

牛牛没来，菜菜来了。

1、superiority 后面只能跟to,而且时态不对，所以b错。

2、was省略了。白勇语法里面并列结构的省略中，就举了这个例子。尽管prove本身就可以主动表被动，但是一般是n. +prove + n./adj 。本句中，prove后面什么也没有，说明用了被动语态，was被省略。
