A recording system was so secretly installed and operated in the Kennedy Oval Office that even Theodore C. Sorensen, the White House counsel, did not know it existed.
A recording system was so secretly installed and operated in the Kennedy Oval Office that
So secret was a recording system installation and operation in the Kennedy Oval Office
It was so secret that a recording system was installed and operated in the Kennedy Oval Office
A recording system that was so secretly installed and operated in the Kennedy Oval Office
Installed and operated so secretly in the Kennedy Oval was a recording system that
题目分析：
通读原句，我们知道，“一个记录系统在the Kennedy Oval Office的秘密建立和运营”以及“Theodore C. Sorensen不知道这个记录系统的存在”之间应该具有因果关系（so that），可以排除(B)(D)；(C)中的so that位置不对，放在此处使得install和know两句之间缺少连词；(E)试图用倒装结构来表达，但是此处倒装结构有问题，应该是：so secretly installed and operated in the Kennedy Oval was a recording system that（完全倒装），排除(E)，答案为(A)。
选项分析：
略
E应该是so secretly Installed and operated in the Kennedy Oval was a recording system that……
so secretly副词/修饰状语倒装，起强调作用。
倒装：
if句倒装：助动词/be动词+主语+谓语动词原型=if sb do sth
否定副词前移：否定副词+助动词/be动词+主语+谓语动词原型，如：
Seldom do I go to work by bus.
地点、范围介词短语前置：地点、范围介词短语+谓语动词+主语，如：
Among the surest indications of sunspot cycles is the rate at which trees grow.
than等引导的被比较部分引导的句子某一成分过长，或复合句里某一成分过长，而将另一成分前置以便于理解，引起的倒装。
