Affording stratigic 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 A would nerver be secure.
C their grip on A was not ever secure if they did not hold it
D without that, they could never be secure about their grip on A
E never would their grip on A be secure if they did not hold it
答案是B,
可是D选项中,答案上解释说without that中的that应该指代Morocco,所以用it~~请问指代时it&that有什么区别?还有,这里如果指代Morocco,句意我又不理解了。。。求讲解!!非常感谢 |
