[求助]一道语法题

Once the economic and social suefulness 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 horsehaving been

答案是B,

问题:

1,had been proved,prove 可以用主动形式表被动,为什么这里涌被动,

2,为什么用过去完成时, 没有明确的时间状语,前面的分句用的是过去时.

3,我认为C正确, its superiority to the horse proved 可以看成是省略了WAS,这样认为有什么错吗?

请多指教

我同意选C.

1. 用被动比较合适。什么什么被证明...，而且与前半句平行。

2. 不能用过去完成时。否则说明两个并列的条件发生的时间顺序不一样，后者比前者还要早。从句子意思来看，没这个必要。

3. 我觉得两个从句并列的时候是可以省略be动词的。见OG一例:

218.       Despite protests from some waste-disposal companies, state health officials have ordered the levels of bacteria in seawater at popular beaches to be measured and that the results be published.

(A) the levels of bacteria in seawater at popular beaches to be measured and that the results be

(B) that seawater at popular beaches should be measured for their levels of bacteria, with the results being

(C) the measure of levels of bacteria in seawater at popular beaches and the results to be

(D) seawater measured at popular beaches for levels of bacteria, with their results（E）

(E) that the levels of bacteria in seawater at popular beaches be measured and the results

manhattan 的解释，我选的也是c。

I received a PM asking me to respond.

I agree with the choice most of you have chosen: C.

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.

Once A <happened> and B <happened>, <C followed>.
dependent compound clause, independent clause.

So, first, we need that "and" in there. Eliminate D and E. Second, the A and B in the compound clause need to be parallel.

A uses "was demonstrated" so we need something in the same tense. A uses "being proved." Nope. B uses "had been proved." Nope. C uses "proved," which also seems wrong at first glance - but as someone up above said, we don't need to repeat the "was" in this instance. This is an unusual construct (I can't recall seeing something quite like this on any official questions) but we don't need to repeat the "was" because of the parallel structure.

That allows us to narrow to C without dealing with the idiom issue (superiority to / over). I have not seen this particular idiom used on an official question, so I cannot say what the official testwriters would prefer here. Both are used in common English, which leads me to believe that either is fine, but there are cases of other common usages that the testwriters don't like and don't consider correct, so... unless they officially comment on the issue (that is, release a question with an explanation that indicates one usage is wrong), we're kind of stuck on this question.

In general, if you can solve a problem using other hard-and-fast grammar rules, do so. In this case, we know we need the "and" (eliminating D and E) and we know we need parallelism (eliminating A and B), so we can ignore the "superiority" issue altogether.
