【呼唤版主】OG12 67（C选项it指代问题）

yingsuanna06

67. Affording strategic proximity to the Strait of Gibraltar,
Morocco was also of interest to the French throughout
the first half of the twentieth century because they
assumed that if they did not hold it, their grip on
Algeria was always insecure.

(A) if they did not hold it, their grip on Algeria was always insecure
(B) without it their grip on Algeria would never be secure
(C) their grip on Algeria was not ever secure if they did not hold it
(D) without that, they could never be secure about their grip on Algeria
(E) never would their grip on Algeria be secure if they did not hold it

答案B

怎么选出来的我理解了，只是OG在C解释是：

C    pronoun it is ambiguous and could refer to either Morocco or Algeria.

但白勇书上讲it的指代原则不是优先指代主句的主语，其次是宾语么？为什么这里it还可以指代Algeria? it的指代原则是什么？

谁能帮着解释一下为什么D 中 without that 不行

谢谢了

个人认为，BY说的代词指代应该优先指代主语中的主语没问题。但是这个it位置是在（assumed） that……引导的从句中的 if……条件从句中的，所以会有歧义产生。到底应该优选哪个主句？只要有指代不清的可能，我认为肯定是不选的。

不对的话请指正！

顶

只能说b简洁。两个我觉得都没错。

that后面好像必须跟名词，不可以单独出现，但是it可以

呵呵，我也在看这题。同问LZ 的问题。

外加一个 D选项， 为啥OG 解释要用it而不可以用that， 两者有啥区别吗？
(D) without that, they could never be secure about their grip on Algeria
