答案选A，但是我觉得A的it明显指代不一致啊。前面的it是形式主语，后面的it就指代不一致了。这个也是语法笔记上讲的，我还记在笔记本上，对照看了好几遍，还是不解，为何要选A,我选的E。请CDer们解惑,谢谢！

选A。it分别作形式主语和指代邮报
B.后面and不平行
C.句子主语改变 意思错误
D.没有谓语动词
E.Katharine Graham's becoming its publisher in 1963错误

第一个it不作代词指代，就不会有指代混淆了吧。

问题是有3个it,这3个it的指代都不一样，这不是造成指代不一致了吗？老版PREP2 第8题的语法解释
Ozone, a special form of oxygen that screens out harmful ultraviolet rays, reaches high
concentrations twelve miles above Earth, where it has long appeared that it was immune from
human influence; we have now realized, though, that emissions of industrial chlorofluorocarbons
deplete the ozone layer.

(A) has long appeared that it was immune from
(B) has long appeared to have been immune from
(C) has long appeared as being immune to
(D) had long appeared immune to
(E) had long appeared that it was immune to  

句子结构：Ozone, …, reaches high concentrations … above Earth, where... ; we have now realized
that…
分号隔开意思并列的两个句子。第一个句子主语是oxygen由that引导的定语从句修饰，谓语是
reaches，where引导定语从句修饰Earth，该从句是主系表结构，appear作系动词，immune to human
influence是表语。




考点：动词形式、指代一致
1)     动词形式-过去完成时，很多情况下，过去时间由上下文表示出来，不需要表示过去时间的状语。
2)     指代一致，形式主语it指代了句子的真正主语（真正的主语在句子后部），因为有所指，所以句子
中如果再出现其它有所指的it，就使it指代不一致，是错误的用法。

(A) it has long appeard that中it是形式主语，后面的it是指Ozone，两个it指代对象不一致。
(B) appeared to have been immume中的现在完成时多余，因为前面has appeared已经表达了完成时
态。
(C) appear as being用法错误。
(D)    正确，appear用作系动词，immune是adj.，简洁明了。分号后面是have now realized，强调now，
用了现在完成时，分号前面的long强调与现在的对比，用过去的时态较合理。
(E)    两个it指代不一致。

查了下前人的帖子，有人说前面的it是强调结构，即“it+be动词+强调部分+who(m)或that+其他部分” 没有指代，故没有和后面it冲突，不过怎么分辨是形式主语还是强调结构希望NN们解释一下..谢谢
作者: azhongzhong    时间: 2011-8-3 11:18
对，如何区分是强调句还是形式主语，一直搞不懂，请大牛们来解释！谢谢！
