I had lived there for over thirty years ___________I wanted to return to my motherland again.

题目

I had lived there for over thirty years ___________I wanted to return to my motherland again.
A.until B.after C.while D.when
此处为什么选D?不选A?

答案

这里的意思是 当我想回祖国的时候我已经在哪里生活了30多年了.
until一般跟not一起使用,如果要选A而且要表达相同意思的话 应该这样I did not want to return to my motherland again until I had lived there for over thirty years.
