标题: OG 57(条件状语问题)

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

(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

Grammatical construction + Verb form

Conditional constructions require specc verb tenses. For a past condition, the subordinate clause introduced by if uses the past indicative, and the main clause uses the conditional if x happened, then y would happen.

这里使用的是“虚拟语气”吗？为什么不能仅仅是条件状语从句，强调条件和结论的关系？

OG是說"if X happened, Y would happen"是條件結構"if X happens, Y will happen"的過去時態.

谢谢版主。
