解析：考察强调句型和定语从句。定语从句的关键在于分析句子结构，定语从句中如果既不缺主语，也不缺宾语和表语，就要考虑是否用关系副词或whose作定语，意为“谁的”。至于如何判断缺不缺主或是宾语，尤其是缺宾语的情况，要将先行词带到定从中谓语动词之后看是否符合逻辑搭配，如符合则缺宾语，如不符合就不缺。同时强调句型在高考中每年必出，关键是要会判断，平时练习时要有这个意识。it is /was+被强调部分+that/who+…判断方法是去掉it is /was that/who句子不缺成分，即为强调句型。本题第一句是强调句型的特殊疑问句。第二空考察的是定语从句。后面省略了that he picked up his uncle at the airport.故D正确。
