“某人已經(jīng)做了某事”等意思時,英語要用“現(xiàn)在完成時”來表達。6否定句Ihavenotworked.He/Shehasnotworked.Theyhavenotworked.

肯定句Ihaveworked.He/Shehasworked.Theyhaveworked.haven’thasn’thaven’t現(xiàn)在完成時的結(jié)構(gòu)：has/have+done(動詞過去分詞)7She/He/It/或sb.的單數(shù)形式hasdonesth.I/We/You/They或sb.的復(fù)數(shù)形式havedonesth.現(xiàn)在完成時的一般疑問句形式是：Hasdonesth.?she/he/it/或sb.的單數(shù)形式Havedonesth.?I/we/you/they/或sb.的復(fù)數(shù)形式現(xiàn)在完成時的肯定形式是：8我父母曾經(jīng)坐船去大連旅游。她已經(jīng)完成作業(yè)。我父母未曾坐船去過大連旅游。MyparentshavetravelledtoDalianbyship.Shehasfinishedherhomework.Myparentshaven’ttravelledtoDalianbyship.9她還沒有完成作業(yè)。你父母曾經(jīng)坐船去大連旅游過嗎？她已經(jīng)完成作業(yè)了嗎？HaveyourparentstravelledtoDalianbyship?Hasshefinishedherhomework?Shehasn’tfinishedherhomework.10要表達“剛剛做完某事”“已經(jīng)做完某事”時，我們同樣可以用現(xiàn)在完成時。例如:Ihavejustheardthenews.Astronautshavealreadybeentothemoon.可以看出，just用來表示“剛剛”，already用來表示“已經(jīng)”，一般置于have/has之后，兩者都用于肯定句，在否定句中則要用yet,表示“還（未）”。例如：Thescientistshaven’theardfromit

yet.11

havebeento

thebookshop.——他到書店去了。14與現(xiàn)在完成時連用的幾個副詞：肯定句:疑問句和否定句:yet常置于句末already,never,ever,just一般置于助動詞have/has之后，過去分詞之前。already,just,ever,yet,never
