求助OG12-SC 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

我纠结的是A选项
(A) if they did not hold it, their grip on Algeria was always insecure
OG上说if did，would do，所以was应该改成would be

我的想法是：抛开wordy，单纯从意思上来讲
整个虚拟是在assumed that从句中，assumed是过去时态。if did，would do是对现在的虚拟。

过去时态中为什么可以出现在现在的虚拟？难道可以抛开assume的时态，在当时来看 是对现在的虚拟就用修改后的A选项

求高人指点。

我也不明白。。。 同求

这个就应该是虚拟吧？assume说的是假设啊，而且句子的内容也和事实相反啊。我也不明白这个问题，同问！
原句的意思应该是说“与过去事实相反”吧？？？

这个assume后面应该不是虚拟，would be只是介于assumed过去时从句中的过去将来时。
