第二篇：比較一般過去時與現(xiàn)在完成時

比較一般過去時與現(xiàn)在完成時

1）一般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）一般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等，皆為具體的時間狀語。?

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等，皆不確定的時間狀語。?

共同的時間狀語：this?morning,?tonight,?this?April,?now,?already,?recently,?lately?等。?

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.。?

4）一般過去時常用的非持續(xù)性動詞有come,?go,?leave,?start,?die,?finish,?become,?get?married等

例如：?

I?saw?this?film?yesterday.?（強(qiáng)調(diào)看的動作發(fā)生過了）?

I?have?seen?this?film.?（強(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??（強(qiáng)調(diào)起床的動作已發(fā)生過了）?

Who?hasn't?handed?in?his?paper??（強(qiáng)調(diào)有卷子未交，疑為不公平競爭）?

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)）?

5）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.

▲時間狀語不同：

現(xiàn)在完成時already,yet,just,never,everbeforefor+時間段，since+時間點(diǎn)// 一般過去時句子一般過去時時間段+ago,just now,yesterday,last week 等表過去的時間狀語▲基本結(jié)構(gòu)不同：

第四篇：13 - 一般過去時與現(xiàn)在完成時的轉(zhuǎn)換

一般過去時與現(xiàn)在完成時的轉(zhuǎn)換

在現(xiàn)在完成時中，延續(xù)性動詞能與表示一段時間的狀語連用，瞬間動詞卻不能。但是，可用別的表達(dá)方式：

①瞬間動詞用于“一段時間 + ago”的一般過去時的句型中；

②瞬間動詞可改成與之相對應(yīng)的延續(xù)性動詞及短語，與一段時間連用；

③瞬間動詞用于“It is + 一段時間 + since + 一般過去時”的句型中，表示“自從……以來有……時間”的意思，主句一般用it is來代替It has been;

④瞬間動詞用于“Some time has passed since + 一般過去時”的句型中。

請看：

A.He joined the League two years ago.B.He has been in the League for two years.C.It is two years since he joined the League.D.Two years has passed since he joined the League.
