only .....but also 怎么用倒桩

Not only置于句首句子必须部分倒桩，即not only后的句子的谓语动词如果是be动词(am,is,are,were ,was)，be动词提到主语前面；若是情态动词（如can，could，would，will），情态动词亦要提到主语前面；若为完成时态，则根据时态、主谓一致将助动词（have，has，had）提到主语前面，后面不变；其他动词根据时态、主谓一致将助动词（do，does，did）放到主语前面，后面动词变成原来形式。例：They not only talked but also shouted and laughed.他们不只谈话，而且喊叫大笑。改：Not only did they talk but also shouted and laughed.注：but also后面的不管。
