During the years _______, he worked as a doctor inthe hospital. A. followed B. to follow C. following D.that followed 答案选D 没问题 定语从句用法可以理解。 可是A 为什么不可以? 例如:With the situation changed, the young workers must study advanced technology.
During the years, he worked as a doctor in the hospital. “that followed”是一个定语从句,that 如果省略,就变成了非谓语动词范畴,强调“被动”的含义,但 句子主语he, follow 与 years之间不存在主、被动关系,所以这里的"that"不可以省略
With the situation changed, the young workers must study advanced technology. 中的situation是“被改变”,非谓语动词中的“过去分词”强调“被动”的意味,与With构成伴随状语,所以这里不可以加“that”, 楼主在此处对语法现象的判断发生了混淆。
