单选题 ______, 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

【正确答案】 A

【答案解析】[解析] being是be的现在分词形式。因为分词的逻辑主语与分词之间的关系为主动，分词所表示的动作又与谓语动词所表示的动作同时发生。分词的独立结构在句中作状语，表示条件。
