Question

when asked if she owned any .这个when引导的时间状语中ask和if的用法,主谓宾关系是什么,

Answer 1

我解答如下：
一、这是一个省略句结构,补全一下就是：When (you are) asked if she owned any ...当你被问到她是否有过 ...的时候,...看起来,这里 "When" 是连接副词,引导一个过去分词短语做时间状语.但实际上这是由连接副词“When” 引导一个被动语态形式的时间状语从句的省略句,后面 "if“ 引导的是“宾语从句”,而不是“条件状语从句”,严格地说,引导宾语从句“if” 应换成 “whether” 才规范,不过在口语中“if” 也行,只是不那么正式和规范.
二、这个句子是由“主动语态的双宾语”结构演变而来的,即：“When they ask you if she owned any ...,” 这时,"you" 是间接宾语,"if she owned any ..." 是直接宾语从句,变成被动语态后,原来的直接宾语仍然存在,称为“保留宾语”,例如：
主动语态：They asked me a question.( me：间接宾语,a question：直接宾语)
被动语态：I was asked a question (by them).( 原来的宾语“a question” 仍然保留,作为保留宾语).所以,原句子中,“ if she owned any ...” 是一个“保留宾语”从句.
再举个例：
主动语态：When they ask you if she owned any foreign currency before,just tell them the truth.
被动语态：When (you are) asked if she owned any foreign currencu before,just tell them the truth.
