“某人已經(jīng)做了某事”等意思時(shí),英語(yǔ)要用“現(xiàn)在完成時(shí)”來(lái)表達(dá)。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(shí)的結(jié)構(gòu)：has/have+done(動(dòng)詞過(guò)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(shí)的一般疑問(wèn)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(shí)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(guò)大連旅游。MyparentshavetravelledtoDalianbyship.Shehasfinishedherhomework.Myparentshaven’ttravelledtoDalianbyship.9她還沒(méi)有完成作業(yè)。你父母曾經(jīng)坐船去大連旅游過(guò)嗎？她已經(jīng)完成作業(yè)了嗎？HaveyourparentstravelledtoDalianbyship?Hasshefinishedherhomework?Shehasn’tfinishedherhomework.10要表達(dá)“剛剛做完某事”“已經(jīng)做完某事”時(shí)，我們同樣可以用現(xiàn)在完成時(shí)。例如:Ihavejustheardthenews.Astronautshavealreadybeentothemoon.可以看出，just用來(lái)表示“剛剛”，already用來(lái)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

與havegoneto

的區(qū)別

1.（1）have/hasbeento意為“曾經(jīng)去過(guò)某地”，表示現(xiàn)在已經(jīng)不在那里了?？膳cjust,ever,never等連用。例如：I’ve

just

beento

thepostoffice.我剛才去郵局了。Have

youever

beento

Hangzhou?你曾經(jīng)去過(guò)杭州嗎？Mary

has

never

theGreatWall.瑪麗從未去過(guò)長(zhǎng)城。12（2）have/hasbeento后面可接次數(shù)，表示去過(guò)某地幾次。I’ve

beento

Beijingthreetimes.我去過(guò)北京三次。They

havebeento

thatvillageseveraltimes.他們已經(jīng)去過(guò)那個(gè)村莊好幾次了。132.have/hasgoneto意為“到某地去了”，表示到了某地或正在去某地的途中。總之，說(shuō)話時(shí)該人不在現(xiàn)場(chǎng)，一般不用第一、第二人稱(chēng)代詞作句子的主語(yǔ)。例如：

—WhereisTom?——湯姆在哪里？

—He

hasgoneto

thebookshop.——他到書(shū)店去了。14與現(xiàn)在完成時(shí)連用的幾個(gè)副詞：肯定句:疑問(wèn)句和否定句:yet常置于句末already,never,ever,just一般置于助動(dòng)詞have/has之后，過(guò)去分詞之前。already,just,ever,yet,never
