________, it began to rain unexpectedly.

A．While cleaning the machine

B．To clean the machine

C．He was cleaning the machine

D．While he was cleaning the machine

答案

解析

试题分析：考查句子结构。后面句子的主语是it说明AB错误，因为要使用非谓语动词做状语，要求非谓语动词的逻辑主语是句子的主语。C项是一个完整的句子，逗号后面也是完整的句子，两个句子之间缺少连词连接，故C错误。句意：当他在清洁机器的时候，突然开始下起雨了。故D正确。
点评：两个句子之间必须有连词连接，如果没有连词，那么其中一个就要变成短语的形式来呈现。
