1、..,,一般過去時與現(xiàn)在完成時的區(qū)別:,,,A從形式結構上區(qū)別 一般過去時的形式結構為： 1主語+動詞的過去式+其它。如： He was a teacher. 他當過教師。 Mr. Brown gave us talk yesterday. 布朗先生昨天給我們做個報告。 The old man told an interesting story. 那位老人講了一個很有趣的故事。,,2現(xiàn)在完成時的形式結構為： 主語+have(has)+動詞過去分詞+其它。如： We have learned two thousand English words. 我們已經(jīng)學過了兩千個英語
2、詞。 She has gone to Beijing. 她已經(jīng)去北京了。,,B從狀語上區(qū)別 1一般過去時常用的副詞狀語有：then, just now等，以及時間狀語有：yesterday, last week, two years ago等。如： They went to the park yesterday. 昨天他們?nèi)ス珗@了。 Last year I saw that film. 我去看過那部影片。,,2現(xiàn)在完成時常與yet, already,ever,never just等以及由for +時間名詞和since時間名詞連用。如： He has already fini
3、shed his homework. 他已經(jīng)完成了家庭作業(yè)。 Have you seen that TV play yet? 你看過那個電視劇嗎？ We have studied English for three years. 我們已經(jīng)學了三年英語了。,,C從否定、疑問結構上區(qū)別 1一般過去時的否定式、疑問式多是借助動詞did來體現(xiàn)（be的疑問式除外）。如： Tom said a word. 否定式：Tom didnt say a word. 疑問句：id Tom say a word? 反意疑問式：Tom said a word, didnt he? 2 現(xiàn)在完成時的否定式、疑問式多
4、是借動詞have (has)來體現(xiàn)的。如： You have looked up that word. 否定式：You haven t looked up that word. 疑問式：Have you looked up that word? 反意疑問式：You have looked up that word, haven t you?,,1since與for since可接時間點，或從句，從句用一般過去時；for接時段，這兩詞都是回答how long的。如：since 1990，since two years ago；for two days。 2already，yet，never，be
5、fore，just都可以用于完成時，但用法不盡相同。 already用于肯定句的陳述句中間， yet用于否定句或疑問句末。 never是“從來沒有”之意， just是“剛剛，剛才”之意，都用于句中， before當副詞用，與表一段時間的詞連用用于完成時，即時間段+before，如two years before；但注意與之同義的ago，是這樣用的：時間段+ago，用于一般過去時。,,3現(xiàn)在完成時與一般過去時的區(qū)別 現(xiàn)在完成時表示過去發(fā)生或已經(jīng)完成的某一動作對現(xiàn)在造成的影響或結果，或表示過去已經(jīng)開始，持續(xù)到現(xiàn)在的動作或
6、狀態(tài)。一句話，現(xiàn)在完成時與現(xiàn)在有聯(lián)系；而一般過去時，發(fā)生在過去但與現(xiàn)在沒有聯(lián)系，且各自的時間狀語明顯不用。,延續(xù)性動詞表示是動作是一種延續(xù)的動作，這種動作可以延續(xù)下去或產(chǎn)生持久的影響。Eg: study , work , keep , have , wait , sing , sleep , live 等。,4. 延續(xù)性動詞與終止性動詞,終止性動詞表示的動作不能延續(xù)，即動作發(fā)生后立即結束，產(chǎn)生某種結果，動作不能再繼續(xù)下去。Eg: come , leave , die , arrive , begin , finish , buy , borrow , open 等。,記住下列終止性動詞改為延續(xù)
7、性動詞的表達法： A. 動詞改為“be + 相應的介詞” 如：come --- be in， B. 動詞改為 “be + 對應的形容詞” 如：close --- be closed open --- be open die ----- be dead finish , end ----- be over get up --- be up leave ---- be away （from）， begin , start ---- be on go out --- be out fall asleep ---- be asleep C.其它改法 如： become ---- be buy --
8、-- have borrow --- keep join the army ---- be in the army (be a soldier ) join the Party ---be in the Party (be a Party member) catch a cold ---- have a cold,。,5have been to，have gone to，have been in三個謂語動詞含義不同。have been to表示“曾經(jīng)去過某地”（但人已回）；have gone to表示“已去某地”（人未回），它們都不能與since和for連用。have been in表示“已
