3．Sometimes we have to face embarrassing moments ________ we can only keep silent．（ ）| A． | who | B． | which | C． | when | D． | why |
分析 有时我们不得不面临一些尴尬的时候，在这些时候我们只能保持沉默．
解答 答案C．分析句子结构可知，主句为"Sometimes we have to face embarrassing moments"，空格处到句末作名词"moments"的后置定语，先行词为"moments 指代时间"，定语从句中不缺少主、宾、表等主要成分，缺少时间状语，因此应该用关系副词when，故选C．
点评 本题考查定语从句．解答此类题目首先要读懂句意分析成分，找出先行词和定语从句．然后分析定语从句中是否缺成分，如果缺少主宾表，要用关系代词（which、that、who、whose、whom、as），如果缺少状语，要用关系副词（where，when或why）．
