Question

什么时候for加时间段不用完成时

Answer 1

您好，很高兴为您解答如下：

for +一段时间不一定用现在完成时，只要这个句子的谓语动词是延续性的，什么时态都可以用。
比如： I'll be away for some time.
He once worked in Janpan for 3 years.
也可以参看下面几道高考题：
1. --- I’m sure Andrew will win the first prize in the final.
--- I think so. He _______D____ for it for months. （2008江苏卷）
A. is preparing B. was preparing C. had been preparing D. has been preparing
2. He __B___ football regularly for many years when he was young. （2008天津卷）
A. was playing B. played C. has played D. had played
3. We first met on a train in 2000. We both felt immediately that we ___C___ each other for years. (2008辽宁卷)
A. knew B. have known C. had known D. know

主要根据基于目前情况下所想表达的时间
