No worker and no engineer who it is that is for the explosion of the chemical factory.
A. know; to blame
B. would know; blamed
C. know; to be blamed
D. knows; to blame

A. know; to blameB. would know; blamedC. know; to be blamed(答案→)D. knows; to blame解析：句意：没有工人和工程师知道，到底谁应该为化工厂的爆炸负责。each,every,no所修饰的名词即使以and或是逗号连接成多个并列主语，谓语动词仍用单数形式。No worker and no engineer虽然是and连接，但是谓语动词要用单数形式，sb be to blame for sth某人因某事而被责备，主动形式表被动意思。固定结构，故选D.
