( ),a man who expresses himself effectively is sure to succeed more rapidly than a man whose command of language is poor .
A：Other things being equal
B：Were other things equal
C：To be equal other things
D：Other things to be equal
A
【译文】在其他条件等同的情况下，一个语言表达能力强的人必定要比一个语言表达能力弱的人更快成功。
【解析】“名词+现在分词短语”可以构成“独立主格结构”，在语义上相当于一个“状语从句”，其中的名词充当逻辑主语，而现在分词短语则充当逻辑谓语；A项满足上述要求，在语义上相当于一个条件状语从句：If other things are equal,故答案选A。
B项Were other things equal是虚拟条件句的倒装，正常语序是If other things were equal，但它与题干的谓语动词（真实语气）is不一致，故是干扰项；C项To be equal other things不存在这样的表述，equal作为形容词不可能修饰other things； D项Other things to be equal,不定式表示未来，而本句则在阐述一个客观存在，故D项也错。
