标题: 请教855-10-15

1. 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

(D) its superiority over the horse（C）

(E) with its superiority to the horse having been

答案是C,我选了B.

1. 请教superiority的用法;

2.C的结构是不是A be -ed and B -ed?材看到好几题有这样的结构,是不是and后面的BE动词被省略了,这种省略在什么情况下可以用呢?

1－superiority over/to 都可以用。

2－当助动词表达的时态一致时，在逻辑允许的条件下，重复出现的可以省略。B的错误在于时态，原文表达的demonstrated和proved都是一般过去时，表示在过去一起发生，而B的过去完成时则表明proved发生在demonstrated前，改变句意，而且不复合逻辑。
