新手上路, 再问 大全710=OG229

这题还是不明白,请大侠们指点

 The colorization of black-and-white films by computers is defended by those who own the film rights, for the process can mean increased revenues for them; many others in the film industry, however, contend that the technique degrades major works of art, which they liken to putting lipstick on a Greek statue.

(A) which they liken to putting lipstick on a Greek statue

(B) which they liken to a Greek statue with lipstick put on it

(C) which they liken to lipstick put on a Greek statue

(D) likening it to a Greek statue with lipstick put on it

(E) likening it to putting lipstick on a Greek statue

我的理解: (如果不对的地方请大家指点)

A, B, C 不对, 画线部分的they, 指代有歧义, 可以指代前半句中的  those who own the film rights, 也可以指代 many others;

另外,这里如果用 they表达人的话, 句子的意思也错误了,因为这里想表达一种比喻, "好比给一尊希腊的雕像涂口红",

如果指人的话,含义就表达成"他们给希腊的雕像涂口红",显然含义不对了.

所以 A, B, C 是不的.

D 中两个it, 第二个it 指代的是 Greek statue, 但是第一个it, 显然不指Greek statue, 两个it, 指代不一致, 也不可以选

结果就只能指E, 符合逻辑上的句子意思, 给一个希腊雕像涂口红, 但是我不清楚这里it 的用法. 不知道哪位高手可以指点一下,这里用哪个语法点可以解释这个it呢?

非常谢谢大家, 新手发贴, 希望大家帮助
