过去完成时的自我介绍 

   Hello, everyone! 认识我了吗?我是过去完成时态啊,是不是觉得和现在完成时态有些相似处呢?这样吧,来听听我的自我介绍吧!

<表现形式>

1. 基本形式:had + 过去分词。

  2. 否定形式:had + not + 过去分词(had not照样可缩写hadn't)。

  3.一般疑问形式:had提到句首,回答用Yes, 主语 + had. / No, 主语 + hadn't. 例如:

  --- Had she told you to go there earlier yesterday? 她昨天告诉过你早点儿到那儿吗?

  --- Yes, she had. / No, she hadn't. 是的,她告诉了。/ 不,她没有。

4. 被动语态形式:had + been + 过去分词。如:

When I got there, the windows had been broken. 当我到那儿时,窗户已经被打破了。

<最佳拍档>

我可是个相对的时态,自然不能离开过去某时 / 动作而“独闯天下”,只能早于过去某时 / 动作,或频频“光顾”于主句为一般过去时的宾语从句中,所以already / yet / still / just / before / never / by(the end of)last year 等时间状语常来“配合作战”;也常活跃在after / before / when + 过去时态从句或by the time + 过去时态从句等的主句中。如:

By the time we got there, she had left. 当我们到达那里的时候,她已经离开了。

<与其他时态间的联系与区别>

  1. 与一般过去时态“小同大异”:我和一般过去时都可指动作发生在过去,但我强调动作相对于过去某一时刻已经完成;而一般过去时则强调动作发生在过去某一时间或过去经常性、习惯性动作,需要特别注意的是:当动作附带yesterday、last year等过去时间状语时,应用一般过去时态。请区别:

By the end of last year, I had visited seven different cities.

截止到去年年底,我已经参观过七个不同的城市了。

  We learned another English song last month. 上个月我们学了另一首英文歌曲。

  2.与现在完成时态“似是而非”:现在完成时表示动作相对于现在已经完成,其标准对照时间点为现在;而我表示动作相对于过去某一时刻前已完成,其标准对照时间点为过去。试比较:

  I have been there twice. 我去过那儿两次。

I had been there twice before I went to school. 在我上学前,我去过那儿两次。

 

    怎么样,各位,对我有所了解了吗?来到后面的时态训练营一试身手吧!
