这是什么用法,以及最后一句的解释
Were we to do the opposite and pursue personal,local or immediate interests at the expense of the others,both sets of interests would inevitably suffer.
这种句式的用处是什么

Answer 1

语法：当虚拟条件句的谓语动词含有were,should,had时,if可以省略,这时条件从句要用倒装语序,即将were,should,had等词置于句首,这种多用于书面语.
这句话的正常语序是：If we were to do the opposite and pursue personal,lacal or immediate interests at the expense of the others,both sets of interests would inevitably suffer.
句意：如果我们相反地,以牺牲其他利益为代价,追求个人利益,局部或眼前利益,那么双方的利益都会遭到损害.
