It would be useless to speculate..
It would be useless to speculate what might have been achieved had these two separate teams been unable to work hand in hand .
这句中的had是什么回事?这句话有没有语法问题?还是一种倒装?had的倒装?
难以理解had的位置和作用.
没有问题
可以这样说:
what(...)had...been...
原句应是(these two separate teams)had been ...但这一部分是what所问的内容,不再是一个独立的句子,所以要倒装
