現(xiàn)在完成時與一般過去時的比較

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，強調(diào)動作；現(xiàn)在完成時為過去發(fā)生的，強調(diào)過去的事情對現(xiàn)在的影響，強調(diào)的是影響。Isawthisfilmyesterday.（強調(diào)看的動作發(fā)生過了。）Ihaveseenthisfilm.

(強調(diào)對現(xiàn)在的影響，電影的內(nèi)容已經(jīng)知道了。）新概念英語-第2冊-第4課-Lesson-4--2一般過去時常與具體的表示過去的時間狀語連用;現(xiàn)在完成時通常與模糊時間狀語連用或無時間狀語。一般過去時的時間狀語:

yesterday,lastweek，…ago,in1990,inOctober,justnow,…--具體的時間狀語

現(xiàn)在完成時的時間狀語:

for,since,sofar,ever,never,just,yet,till/until,uptonow,inthepastfewyears,recently,…--模糊的時間狀語句子中如有過去時的時間副詞（如yesterday,last,week,in1960）時，不能使用現(xiàn)在完成時，要用過去時錯Tomhaswrittenalettertohisparentslastnight.對Tomwrotealettertohisparentslastnight.Grammar新概念英語-第2冊-第4課-Lesson-4--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.

一般過去時常用的非持續(xù)性動詞有come,go,leave,start,die,finish,become,getmarried等。ShejoinedtheLeaguethreeyearsago.(加入的動作不是延續(xù)的)ShehasbeenintheLeagueforthreeyears(sincethreeyearsago).(在團內(nèi)的狀態(tài)可延續(xù))ShehasbeenaLeaguememberforthreeyears(sincethreeyearsago).(是團員的狀態(tài)可持續(xù))

Grammar新概念英語-第2冊-第4課-Lesson-4--延續(xù)動詞表示經(jīng)驗、經(jīng)歷；瞬間動詞表示行為的結(jié)果,不能與表示一段時間的狀語連用。比較延續(xù)動詞與瞬間動詞

Hehasfinishedthework.他已完成了那項工作。(表結(jié)果)

I’veknownhimsincethen.我從那時起就認識他了。(表經(jīng)歷)Grammar新概念英語-第2冊-第4課-Lesson-4--since用來說明動作起始時間—“自從……”for用來說明動作延續(xù)時間長度—“長達……”Ihavelivedhereformorethantwentyyears.
