______ was the first question asked by the policeman.

Question

______ was the first question asked by the policeman.
A．That he went into the room
B．How did he go into the room
C．How he entered the room
D．That he entered into the room

Answer 1

选择C
解析： ①这里是How引导的主语从句作was的主语，正确的结构应该为：“特殊疑问词+陈述句语序”，B选项为疑问句语序致语法错误，故排除B选项；
②另外，enter为及物动词，后面直接加宾语，之间不能加介词into，即应该为：enter the room，D选项多加了into致语法错误，故排除D选项；
③若选择A，意思为：他进入房间是警察问他的第一个问题，意思讲不通，故排除A选项；
④只有C选项的语法和意思都正确，翻译为：他如何进入房间的是警察问他的第一个问题。

Answer 2

C
这是由疑问词how引导的主语从句，用陈述句的语序，排除B。注意中间的be动词，它好像托盘天平的中间的那根横梁一样，两边是相等的，这样天平就会平衡，既然后面的表语是question问题，前面的主语从句就应该用疑问词引导，而不用本身无字义，在从句中不作任何成分，只起连接作用的从属连接词that引导，所以又排除A和D。希望我能帮助你解疑释惑。
