[求助]大全987-8

8         *A huge flying reptile that died out with the dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of 36 feet, believed to be the largest flying creature the world has ever seen.

(A) believed to be

(B) and that is believed to be

(C) and it is believed to have been

(D) which was, it is believed,

(E) which is believed to be

请教：首先，怀疑正确答案C，既然是并列结构，不是说在and 后面要省略相同的主语么？为什么补出了it 呢？

其次，A 选项为什么不能跳跃指代前面的主语呢？这里 TO BE  的后面已经出现了Creature,应该不会造成修饰对象的混淆啊？

请长犄角的老师们帮忙指点

老师谈不上, 大家相互学习.

and这里前面有逗号, 已经开始了新的句子, 可以加主语, 不会造成Run-on.

关于过去分词的跳越, 到目前为止, 我只见过compared可以跳越修饰主语, 其它的基本上修饰结尾的结构, 这里我觉得跳越修饰不好.

并非想和您抬杠，但是，白勇语法243页在解释下题时说道：

            The company is negotiating to sell its profitable credit card subsidiary, which it plans to use money from to acquire some of the mortgage-servicing operations that are being sold by troubled savings institutions.

(A) subsidiary, which it plans to use money from

(B) subsidiary, from which it plans to use money

(C) subsidiary, and it plans the use of money from that

(D) subsidiary and plans to use money from that sale（D）

(E) subsidiary and plans the use of money from that sale

C 选项句子2的主语it 指句子1的主语company,it 应该省略。

OG中也有类似的例子，一时想不起来了。

是不是说这种省略不是判断选项正确与否的必要条件？

盼望您的指教——以师相称，只是表达我对您这种无私助我的行为的敬意，不是奉迎。

hyld严重了.

如果是A do B, do C, and do D的平行结构的话, 肯定不可以中间插入代词破坏平行, 但是如果只有两个的话, 我看OG确是没有注意到解释有明确的说明, 还望hyld示下.

一只想找个OG的例子反驳您。

再一次好好研究了OG,找到了很多反驳自己的例子。

真诚的表示感谢！

guys, it can interpret that " do A ,and do B "  is wrong ,it must input sth like"it " or omit ","?

should be?
