--Yes. I gave it to her ______I saw her.（2001春季高考，14）
A.while B.the moment C.suddenly D.once
答案：B
分析：不少学生误选D，但“once”隐含条件，意为“一旦……就……”，该句理解成“我一旦见到他就把钱给了他”显然不符合上下文的语境，故排除D。“the moment”看似名次词组，但实际上用作连词，引导时间状语从句，故应选B。
注意②：“once”后面的从句中常可采用省略结构。

Once seen ( = Once it is seen )，it can never be forgotten.
一旦见到了就永远不会忘记。
