比較過去時與現(xiàn)在完成時

1)過去時表示過去某時發(fā)生的動作或單純敘述過去的事情,強(qiáng)調(diào)動作;現(xiàn)在完成時為過去發(fā)生的,強(qiáng)調(diào)過去的事情對現(xiàn)在的影響,強(qiáng)調(diào)的是影響。

 

  2)過去時常與具體的時間狀語連用,而現(xiàn)在完成時通常與模糊的時間狀語連用,或無時間狀語。

一般過去時的時間狀語:

yesterday, last week,…ago, in1980, in October, just now, 具體的時間狀語

共同的時間狀語: 

this morning, tonight,this April, now, once,before, already, recently,lately 

現(xiàn)在完成時的時間狀語

for, since, so far, ever, never, just, yet,      till / until, up to now, in past years, always,

不確定的時間狀語

 

  3)現(xiàn)在完成時可表示持續(xù)到現(xiàn)在的動作或狀態(tài),動詞一般是延續(xù)性的,如live, teach, learn, work, study, know.

  過去時常用的非持續(xù)性動詞有come, go, leave, start, die, finish, become, get married等。

 舉例:

  I saw this film yesterday.

 。◤(qiáng)調(diào)看的動作發(fā)生過了。)

  I have seen this film.

 。◤(qiáng)調(diào)對現(xiàn)在的影響,電影的內(nèi)容已經(jīng)知道了。) 

  Why did you get up so early?

 。◤(qiáng)調(diào)起床的動作已發(fā)生過了。)

  Who hasn't handed in his paper? 

 。◤(qiáng)調(diào)有卷子,可能為不公平競爭。)

  She has returned from Paris. 

   她已從巴黎回來了。

  She returned yesterday.

   她是昨天回來了。

  He has been in the League for three years.

  (在團(tuán)內(nèi)的狀態(tài)可延續(xù))

  He has been a League member for three years.

  (是團(tuán)員的狀態(tài)可持續(xù))

  He joined the League three years ago. 

  ( 三年前入團(tuán),joined為短暫行為。)

  I have finished my homework now. 

 

  ---Will somebody go and get Dr. White?

  ---He's already been sent for. 

  句子中如有過去時的時間副詞(如 yesterday, last, week, in 1960)時,不能使用現(xiàn)在完成時,要用過去時。

  (錯)Tom has written a letter to his parents last night.

  (對)Tom wrote a letter to his parents last night.
