be they ...or这是什么语法使用
答
if条件句中,如果省略if,则if从句需要全倒装.
比如 if I were 25,I would marry you.= were I 25,I would marry you.
所以这句话完整的应该是 First of all,relevant laws and regulations should be established to severely punish those who violate traffic rules openly ,if they （should） be drivers or pedestrians.
一旦if省略了,那么假设这个含义就弱了一点,强调这个条件的含义加强.
翻译过来的语义是 首先,相关法律应该严惩那些公然违抗交通法律法规的人,当这些人是司机或者行人的时候.
