第二篇：比較一般過去時(shí)與現(xiàn)在完成時(shí)

比較一般過去時(shí)與現(xiàn)在完成時(shí)

1）一般過去時(shí)表示過去某時(shí)發(fā)生的動(dòng)作或單純敘述過去的事情，強(qiáng)調(diào)動(dòng)作；現(xiàn)在完成時(shí)為過去發(fā)生的，強(qiáng)調(diào)過去的事情對(duì)現(xiàn)在的影響，強(qiáng)調(diào)的是影響。?

2）一般過去時(shí)常與具體的時(shí)間狀語(yǔ)連用，而現(xiàn)在完成時(shí)通常與模糊的時(shí)間狀語(yǔ)連用，或無時(shí)間狀語(yǔ)。?

一般過去時(shí)的時(shí)間狀語(yǔ)：yesterday,?last?week，…ago,?in1980,?in?October,?just?now等，皆為具體的時(shí)間狀語(yǔ)。?

現(xiàn)在完成時(shí)的時(shí)間狀語(yǔ)：for,?since,?so?far,?ever,?never,?just,?yet,?till/until,?up?to?now,?in?past?years,?always等，皆不確定的時(shí)間狀語(yǔ)。?

共同的時(shí)間狀語(yǔ)：this?morning,?tonight,?this?April,?now,?already,?recently,?lately?等。?

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

4）一般過去時(shí)常用的非持續(xù)性動(dòng)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(dòng)作發(fā)生過了）?

I?have?seen?this?film.?（強(qiáng)調(diào)對(duì)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(dòng)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(jìng)爭(zhēng)）?

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(shí)的時(shí)間副詞（如yesterday,?last,?week,?in?1960）時(shí)，不能使用現(xiàn)在完成時(shí)，要用過去時(shí)。?

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

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

第四篇：13 - 一般過去時(shí)與現(xiàn)在完成時(shí)的轉(zhuǎn)換

一般過去時(shí)與現(xiàn)在完成時(shí)的轉(zhuǎn)換

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

①瞬間動(dòng)詞用于“一段時(shí)間 + ago”的一般過去時(shí)的句型中；

②瞬間動(dòng)詞可改成與之相對(duì)應(yīng)的延續(xù)性動(dòng)詞及短語(yǔ)，與一段時(shí)間連用；

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

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

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.
