答案：
A. are science and technology advancing that
B. science and technology advancing are that
C. science and technology are advancing what that
(答案→)D. are science and technology advancing that what
解析：选D考查特殊句式。句意：科学技术进步得如此之快以至于今天的可能性在明天也许就变成了现实。本句“so＋adj./adv.”位于句首，句子要部分倒装，故助动词are应提到主语的前面。so ... that 引导一个结果状语从句，在这个从句中含有一个主语从句，主语从句缺主语，故用what引导。
