Question

（2014山东省实验中学高三第二次模拟考试）7．Perhaps it will never be known __________ he did with those materials on the incident．

A．that B．what C．which D．how

 

Answer 1

B

【解析】本句中的it是形式主语，真正的主语是后面的主语从句what he did with those materials on the incident。在这个主语从句中，what既是引导词也是动词did的宾语。固定搭配do with和what连用；deal with和how连用。句义：也许他如何处理事故中的这些材料永远都不会为人所知。Which指特定范围之内的某一个。That在名词性从句中不充当任何成分。故B正确。
