why he was late是完整的句子,缺少原因状语,用why
that/which/不填 he gave us缺少宾语,完整表达法是he gave us the reason
who/that I saw后缺少宾语 完整为I saw the man
whose father 前少定语 完整为the friend's father
that/which has just left缺少主语,完整为the train has just left
这几道题都是定语从句,判断用关系代词还是关系副词,方法是判断从句中缺少何种成分,如果缺少主、宾、表或定语用关系代词that/which/who/whom/whose/as中选其一,如果缺少状语用when/where/why从中选其一,具体选择哪一个看先行词。
