题目内容
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】句意:有很多健康问题,如果得不到及时处理的话可能会变得很糟糕。此处非谓语动词做条件状语,其逻辑主语是health problems,被动关系,一般式,相当于when they are not treated in time。注意BCD三个选项与A项的区别:B表示非谓语动词的动作与谓语动词同时发生;C项表示非谓语动词的动作发生在谓语动词之后;D项表示非谓语动词的动作发生在谓语动词之前。
【考点定位】考查非谓语动词。
