When finished with is part of calculation, Bharat re-calculated my part with the assumption that I was not good at what I was doing.

如果说Bharat完成了自己的计算，然后来验算我的部分，也就罢了。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
