ten years ago,who could have imagined that they were to have such a big share in the market.
10年前有谁能想象得到它们（这些产品）会在市场上占到如此大的份额.
这里主要都是相当典型的“虚拟语气”的应用：
could have +动词过去分词
were + 动词不定式
这些都是在虚拟语气下的固定用法
请参阅下面链接复习一下就能明白其中的奥妙啦：
Our TV sets sell well, but ten years ago no one could have imaginedD吧应该是不能的因为在这里as不能代替that引导.. c D
C. were to have=would have,此处是一个虚拟语气，主句用了could have imagined,表示与过去的情况相反。“当时有谁能想到他们将能在市场上占有那么大的份额？”所以后半句应该有过去将来时。
选C. were to have=would have,考查虚拟语气，主句用了表示与过去的情况相反。从句应该用去将来时
