When I saw the mess my paper was in,it was obvious that someone it.
A.was reading B.had read C.had been reading D.read
请老师详细讲解这道题为什么选C项而不选其他项啊?谢谢老师啦
When I saw the mess my paper was in,it was obvious that someone it.
A.was reading B.had read C.had been reading D.read
这个句子的时间状语从句的谓语是saw,看到、看见,是一个点时间,如果选A过去进行时,则意味着你看到你的论文凌乱的样子的时候,某个人正在读你的论文。这和It is obvious表示推断就矛盾了。如果选B,过去完成时表示别人偷看完你的论文和你发现论文凌乱的样子之间有一段空白时间,那么按常理,偷看你论文的人应该有充足的时间将你的论文整理好,以防你发现。而此人却没有这样做,说明他没有时间,因为你回来了。选C,过去完成进行时,表示在你看到你的论文凌乱的样子之前,某人读你的论文,一直持续到你回来发现之前刚刚结束(被你的脚步声打断),他没有时间整理你的论文,只顾逃离或躲藏了。这符合逻辑和上下文的意思。选D,一般过去时的动作是发生并结束的完整动作,而这个动作不可能在when从句这个点时间完成,因此是错误。通过以上分析,正确答案是C,其它选项都是错误的或不合逻辑的。

过去完成进行时态
【1】过去完成进行时的定义理解:
表示一个动作从过去某时(A)开始,一直延续到另一个过去(B)时刻,到那个(B)时刻,该动作可能刚刚终止,也有可能还在继续。
(A时间是离现在较久远的过去时间,B是离现在较近的过去时间, A过去时间在句子不体现出来,B 时间在句子体现出来,属于动作截止时间/参照时间.)
A:刚刚终止(结束性用法)
We had been waiting for him for about an hour by the time he came.
当他来的时候,我们等他有一个小时了。(动作刚刚终止)
I had been looking for it for days before I found it.
这东西我找了好多天才找着的。
They had only been waiting for the bus a few moments when it came.
他们只等了一会儿车就来了。
How long had it been raining after he left home?
在他离开家后,雨下了有多长时间了?(动作可能还在进行)
He had been living here before he went to Shanghai.
I had been waiting here for an hour before she called me in.
The telephone had been ringing for three minutes before it was answered.
She couldn’t walk any further. She had been walking the whole day.
B未终止/未结束(持续性用法)
By the end of last month they had been working here for about ten days.
到上个月为止,他们在这里工作大约有十天了。
She said that she had been listening to radio after school.
她说她放学后一直在听收音机。
by the end of +过去的时间,后面句子使用过去完成时态 had done sth
by the end of +将来的时间,后面句子使用将来完成时态will have done sth
She told me that she had been studying French for 5 years.(仍继续)
She told me that she had been waiting for me for an hour. (不再继续)
过去完成进行时是在过去完成时的基础上发展而来的:从“过去”到了“过去”的某条截止线,这是过去完成时;到了截止线后,动作,行为还在进行着,这是过去进行时,两者合二为一便形成过去完成进行时。
————过去的过去————过去(参照点)————现在————→
动作到了参照点后,还在继续,则为过去完成进行时态。
He had been working in the garden for almost two hours when his wife came out to help him .
当妻子出来帮他时,他已经在菜园里工作了差不多两个小时了。
【解析】“妻子出来帮忙”已是过去,在此之前,他在菜园里干了差不多2小时的活,这是过去完成时,妻子出来时他还在干着活,这是过去进行时,2者合并,形成过去完成进行时。
They had been aruging for 20 minutes when their boss came to stop them.
老板前来制止他们是,他们已经争论了20分钟了。
【解析】立足:“现在”看老板制止,已经为过去,在此之前,他们争论20分钟,老板到来时他们还在争论着,2者合一便锁定全部争论行为需要的用过去完成进行时。
How long had the fight been going on before the police arrived?
警察赶来之前,打斗持续了多久?
【解析】警察赶到时截止线,在此之前打斗一直持续,且警察赶到时,打斗仍在进行着,因此用过去完成进行时。
We had been watching the football match for nearly one hour when it began to rain.
天开始下雨时,我们已经观看足球接近1个小时了。
【解析】天开始下雨时截止线,之前一直观看,开始下雨的时候,我们还在观看。
过去完成进行时表示持续到过去某个时间时,这个动作仍在进行的一种状态。(可算是现在完成进行时的过去式):
The ground was wet. It had been raining.
地是湿的。此前一直在下雨。

I had been looking for it for days before I found it.

They had only been waiting for the bus a few moments when it came.

【2】过去完成进行时、结构形式

When I saw the mess my paper was in, it was obvious that someone _______ it.
A.was reading B.had read C.had been reading D.read
【答】“过去完成时”:用来表示在过去某一时间之前或某一动作之前已完成的动作,即“过去的过去”。这个过去的时刻常用by, before 等介词短语或时间状语从句来表示,也可从一个表示过去的动作或上下文中得到提示,也就是我们常说的“参照物”A,那么,动作B发生在参照物A之前:
A: my paper was in a mess 我的论文乱成一团(一般过去时)
B: someone had read it 有人读过它(过去完成时)
▲下面,我给你提供结20个例句,请仔细体会“过去完成时”的用法,为什么使用“过去完成时”?如果改用一般过去时的话,句中两个动作孰先孰后?句子的意思还能不能看懂?(个别句子可以改用一般过去时,但都是能通过明确的时间状语,分出动作的先后。)
