Morocco was also of interest to the French throughout
the first half of the twentieth century because they
assumed that if thev did not hold it. their grip on
Algeria was always insecure.

be secure
(C) their grip on Algeria was not ever secure ifthey
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

本题正确答案是B

想问下：为什么要用if x happened, then y would happen这样的结构？这是虚拟吧，为什么要用虚拟？虚拟这里我一直掌握的不好，求大神讲解，谢谢！

虚拟句用来描述说话人想象的，非真实的情景，这些情景通常是不可能发生的，与客观实际相反的，或发生可能性 ...

感谢感谢，那if X happened, then Y would happen是可以当做惯用说法来记一下吗？

是的.你翻一下曼哈顿语法笔记第7章,关于if then的表达法，根据对then从句情况发生的可能性，有5种相对应的时态呢。

那是assume后面一定要用虚拟吗？还有为什么要用对现在的虚拟呢？不应该用对过去的虚拟吗？ ...

这里不是对什么时候虚拟的问题，这是assumed的宾语从句，宾语从句里的谓语动词时态要与主句的谓语动词时态保持一致，再说了，这种用法很常见，我翻了下曼哈顿，里面关于时态那一章就有一句类似的话：The scientist announced that the supercollider was ready, that it had not cost too much, and that it would provide new insights into the workings of the universe.他的解释是：“The helping verb would expresses the future from the past's point of view"  另外，刚好在THE NEW YORK TIMES也看到一句，我截下来附在下面，希望帮助你理解C:\Users\DNS\Desktop\QQ图片20130730182153.jpg

虚拟句用来描述说话人想象的，非真实的情景，这些情景通常是不可能发生的，与客观实际相反的，或发生可能性极小，表示的是假设或实际可能性不大的情况
题中的assume就暗含了假设的情况
without it their grip on Algeria would never be secure=If they have not been with it,their grip on A would nver be secure.

木以晨夕

assume在这里表示虚拟语气
