Question

— ________when the rainstorm came?

—He was waiting for the bus.

A.What he was doing B.What is he doing

C.What was he doing D.What were he doing

Answer

C

【解析】

句意：——当暴风雨来临的时候他在做什么？——他正在等公交车。

考查过去进行时。What he was doing这是陈述语序；What is he doing现在进行时，疑问语序；What was he doing过去进行时，疑问语序；What were he doing形式错误，he是单数，应用was。根据句中when the rainstorm came可知，这里说的是过去的事情，且表示当时正在做，应用过去进行时；这是一个特殊疑问句，应用疑问语序。故选C。
