关于 ALTHOUGH 的省略 问题， 应怎么省？

1.        Despite no proof that the consumption of any particular foods reverse hardening of the arteries, studies indicate that refraining from eating certain foods could help reverse blockage of coronary arteries, the blood vessels that feed the heart.

(A) Despite no proof that the consumption of any particular foods reverse hardening of the arteries, studies indicate that refraining from eating certain foods could

(B) Despite no foods having been proved to reverse hardening of the arteries when consumed, studies indicate that refraining from eating certain foods can

(C) Although the consumption of no particular foods have been proved to reverse hardening of the arteries, studies indicate that to refrain from eating certain foods could

(D) Although not proved that the consumption of any foods reverse hardening of the arteries, studies indicate that refraining from eating certain foods can（E）

(E) Although it has not been proved that the consumption of any particular food will reverse hardening of the arteries, studies indicate that refraining from eating certain foods can

我的 问题是 若把D 改成 ：

D) Although not proved that the consumption of any foods reverses hardening of the arteries, studies indicate that refraining from eating certain foods can  对吗 ？

  Although 等的省略，怎么用阿？  

谢谢 rosmarine

我 是说 若 不管 D的主谓一致 问题

  although  和 not proved 中间 的省略，因该 怎么省？ D 选项的省略对吗？

1还有这道题：

.        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.

(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（C）

(E) with its superiority to the horse having been

答案C说是 proved 前 省略了 was,  为什么 可以这样省/?

你的 第一题解答的很清楚。。that  同位语从句无所指。。 我懂了。。

但是 有没有这种可能，即D 选项是 这样 补充 的。---（宾语从句 例如：Tests have proved that the system works）

Although studies did not prove that the consumption of any foods reverse hardening of the arteries, studies indicate that refraining from eating certain foods can

这样 的解释 又怎么说？？

这一题，我在发个新贴， 有准确解释了，我通知你，。谢谢你的 帮助。。非常感谢

谢谢  rosmarine 。。 我知道了。 太钻牛角尖了。

呵呵。 祝 rosmarine 好运
