So forcefully ____ that we were all convinced.

So forcefully ____ that we were all convinced.
A、he did speak
B、he spoke
C、did he speak
D、that he spoke
【正确答案】：C
【题目解析】：【考点点击】本题考查倒装句型。【要点透析】在so.that.结构中,如果把so置于句首,主句则要用倒装语序。suchtht的结构用法与so.that.相同。此外,否定词及含否定意义的词如 little,few等,放于句首时句子也用倒装结构。如 Little does he know about it.“他对此几乎一无所知”。
