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!
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。
我可是个相对的时态,自然不能离开过去某时刻动作而“独闯天下”,只能早于过去某时刻动作,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。
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:
a.By the end of last year, I had visited seven different cities.
b.We learned another English song last month.
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!
