白勇语法一题疑惑

Austen1985

请大家帮忙分析一下，白勇语法分词那章习题，18题

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.

(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 over the horse having been

我疑惑的是B选项和C选项。答案是B。 说C中，and 连接的once 从句和its superiority 形式不对称。

而我认为，and 可以作为once 从句里的连词，即：once....was demonstrated and ....(was) proved,....系动词在并列结构中是可以省略的。而在B中 was demonstrated 和 had been proved 时态不一致，也没有明确的时间指示说明他们的合理性。

and连接的对象一定要符合平衡对称的原则，所以前面是完整的子句，后面也一定要是完整的子句，如果像您说的省略的方式的话，也应该是Since.....was demonstrated and proved这样吧! 可是二个子句的主语不一样，所以应该没办法把它看做是省略的用法，不过B选也是怪怪的，因为and的特性应该是连接的时态要一致，或是先发生的放前面，后发生的放后面才对，二个答案都怪怪的!

答案是C，白勇第12页，在说明两个句子并列这个知识点时，是那这句话当例句的。

Resilient

I found BaiYong's explanation far from convinving . For example in  OG 218

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

The correct answer is also E where "be" is ommited.

sorry, 我没download，所以不知您们在说啥，可以大概帮我口述一下吗?? (我是台湾的同胞，简体字我看得不是很懂 ) 麻烦您了，因为对这题也是很confused.

我弄个繁体字。

BY提到的省略原則：

兩個句子並列，第一個句子含有Be動詞或者become,第二個句子中的be動詞或者become必須省略，同時，一些重復的名詞或者形容詞也必須省略，例如：Once the economic and social usefullness of the motor car was demonstrated and its superiority to the horse proved...(proved 前省略了was)

以上是書上的原話。12页。

I see. Thanks!!!

我发现了，是书出了问题，在12页的时候确实用了这句话作例子，就是我的理解，而在习题131-132的习题18题出现了错误，答案选B，实际是C才对。

谢谢各位了！！
