C

试题分析：无论你是多么健谈的人，总有些时候保持沉默更好。此题是no matter how引导的让步状语从句，而主句中又含有一个when引导的定语从句，从句中it是形式主语，而真正的主语是不定式结构to be silent。句型结构为：It + be + 形容词 + (of/for sb.）+ 动词不定式。 点评：动词不定式，动名词或主语从句作主语时，通常用it作形式主语，放到句首，将真正的主语放在后面，常见句型有： 1. It + be + 形容词+主语从句，如： It is uncertain whether he can come to Jenny’s birthday party or not. 2. It + be + 名词词组 + 主语从句，这类名词有：a fact, a pity, a shame, an honour，a question等，如： It’s a pity that you missed the exciting football match.
