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。 |
