i haven't written [not writte]for such along time 这里为什么用过去完成时帮我分析
I have been very busy with study这句也是
the doctor told[tell]me i have to balance my work.这句又用过去时为什么呢?帮我区分一下过去完成时跟过去时有什么区别基础差

现在完成时（Present perfect）是过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在的动作或状态.（对现在有影响,延续到现在还有可能延续到将来）
i haven't written [not writte]for such along time 这里是我很长时间没有写了在过去的时间到现在都没有写了可能延续到将来因此是现在完成时态
同理I have been very busy with study
至于一般过去时表示过去某个时间发生的事、存在的状态或经常发生的动作.说话的侧重点只在于陈述一件过去的事情,不强调对“现在”产生的影响
the doctor told[tell]me i have to balance my work. 医生只是告诉我我需要平衡下我的工作只是侧重医生告诉我这个事实而已不对现在有影响.因此用一般过去时
. 两种时态的区分
（1）一般过去时的谓语动词用过去式,而现在完成时的谓语基本构成是“助动词have /has +过去分词”.如：
（2）一般过去时通常与表示过去的时间状语连用.如：yesterday, last week, two years ago, just now, in 2002等；而现在完成时则常与just, already, ever, never等副词和these days, this week, since..., for...等表示一段时间的状语连用.
看看以下的几组句子,有什么区别?
① Have you seen the film?（A）
Did you see the film?（B）
[说明] 你看过这部电影吗?（A）句强调的是被问者对剧情是否了解；（B）句强调的是看这部电影的动作是否发生过,并不强调是否知道其内容.
② How has he done it?(A)
How did he do it?(B)
[说明]他是怎么做的这件事?(A)句强调的是他做这件事的方式对现在产生了某种影响；(B)句单纯的
询问做这件事的方式.
③ He has lived in Beijing for 8 years.（A）
He lived in Beijing for 8 years.（B）
[说明]他在北京住了8年.（A）句讲的是到目前为止他在北京住了8年,可能还会继续在北京住下去.(B)句讲的是他在北京住过8年,现在不在北京了.
希望能够帮到楼主
