(2013·高考浙江卷)There are some health problems that，when ________ in time，can become bigger ones later on.

A．not treated

B．not being treated

C．not to be treated

D．not having been treated

答案

A

解析

选A。题***意思是：“有一些健康问题，如果没得到及时的治疗，在以后会变成更为严重的问题。”分析句子结构可知，此处是状语从句的省略，从句主语problems与treat之间为被动关系，故A项正确，其完整的形式为when they are not treated in time。此句实际上是分隔式定语从句。定语从句that can become bigger ones later on被when not treated in time分隔开来了。
