begin是瞬间动词为什么还有had

begin 是瞬间动词 为什么还有had begun的用法

had begun : [已经开始了]. 是[过去完成]时态, 并不影响该动词是否瞬间动词.

[过去完成时]用法:

表示两组动作发生在过去的不同时间的先后次序. 先完成的动作用[过去完成时],

后完成的动作用[过去时]

例句:

I had eaten an apple when father came home.

(过去)我吃完了一个苹果后爸爸才回家.

When she arrived,the party had already started.

当她抵达时, 派对已经开始了.

He had been a poor man before he became rich.

在他富有之前他是一个穷人.

The film had already begun by the time we arrived the cinema.

电影在我们抵达戏院时已组放映.

begin 是瞬间动词 为什么还有had begun的用法?

begin的确是瞬间动词,它完全可以用于现在完成时态,表示“……已经开始”。例如:When I got to the cinema, the film had already begun.(我到达影院时,电影已经开始了。)只不过瞬间动词不能够与表示一段时间的状语(如:for three days, since I came here等)连用,因为瞬间动词不能够延续;若要表示“……开始多久了”,常用be on表示,如:电影已经开始半个小时了。(The film has been on for about half an hour.) 类似的还有:

(1)I have bought a book.我买了一本书。

购买 buy ——have(拥有)

I bought the book two days ago.

I have had the book for three days.

(2)I have already borrowed a pen.我已经借来了一支钢笔。

借来borrow——keep(保存、保留)

I borrowed the pen last week.

I have kept the pen for a week.

非延续性动词绝对不可以和表示段时间的状语连用,若表示延续性意义,可以转换其他方式或用其他类似的词(或词组)。再如:

他入党三年了。

可译为:

He has been a Party member for three years.

He has been in the Party for three years.

It's three years since he became a Party member.

He became a Party member three years ago.

begin不是不能用于完成时吗?为什么有The meeting has begun.

begin 是非延续性动词,其动作不可延续,一瞬间结束,非延续性动词可用于现在完成时,但不能与一段时间连用,你所提问的句子没提及到时间,所以可以用has begun,但要是用上一段时间,请看例句:

音乐会已开始半小时了。

误:The concert has begun for half an hour.

正:The concert has been on for half an hour.

用,been,beaten,become,begun,blown。各造一个句子,用过去完成时。拜托

My mother opening the window.(用现在完成时改) He got to the cinema.the firm had begun.(用before连

My mother has opened the Window.

The film had begun before he got to the cinema.

when I got to the cinema ,the film had begun.为什么可以,不是要用延续性动词吗?

不一定 过去完成时可以表示过去的过去发生的事情对过去的影响

电影已经开始在我到电影院之前发生,并且相对于那时已经完成,对其构成时间性影响

The bird covered the distance in three minutes.时态为? 助动词 对covered the distance 划线提问

up to now 的同义词组为:so far ,till now , untill now(这三个词组都是现在完成时的标志词,即他们出现时,句子常用现在完成时)

He has begun his own private'telephone' service.时态为现在完成时 ,助动词为has,否定句在Has 后加not,即 He hasn't begun his own private'telephone' service.一般疑问句:Has he begun his own private'telephone' service? 肯定回答:Yes,he has.

另外,看您提的以上问题都是关于现在完成时的具体问题,以下建议您可能用得着:

1 现在完成时的句子结构为:have/has + 动词的过去分词,其中have/has为助动词。

2 一般的陈述句变一般疑问句时,常把助动词提到句首,再加上其他内容,句尾的句号变问号。肯定回答是:Yes,主语(常为人称代词,如you ,i ,he,she等)+助动词

还有什么问题,望追问。谢谢!

1.heard sb do\doing sth

do表示听到全过程,doing表示指示一个片断。这里应该是singing

2.应该是had begun 前面从句已经是过去时,主句应该是过去完成时。
