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

题目分析：巨傻的一道题，划线外用的assumed，就证明划线内的语义应该是没有实际发生的，应该用虚拟语气，这几个选项里用虚拟语气比较正常的只有B（当然有些货会问问什么B正常，B用without it，有的选项用they did not hold it，哪个是人类的表达方式？）如果你又问什么是人类的表达方式？我告诉你，如果意思相同，哪种表达方式最effective？显然是without it，如果有they did这个，多一个代词，我就得琢磨一下了！
