當(dāng)我們談?wù)搫?dòng)作從過去某一時(shí)間開始一直延續(xù)到現(xiàn)在,并且有可能持續(xù)下去時(shí)，我們常常用以下句型來表示:for+一段時(shí)間have/hasbeen+doingsthsince+過去的時(shí)間點(diǎn)since+從句(一般過去時(shí))現(xiàn)在完成進(jìn)行時(shí)eg.Howlonghaveyoubeenswimming?Ihavebeenswimmingfor3years.Howlonghasshebeenskating?Shehasbeenskatingsincenineo’clock.1.現(xiàn)在完成進(jìn)行時(shí):表示從過去開始一直持續(xù)到現(xiàn)在的工作,這個(gè)動(dòng)作可能剛結(jié)束,也可能還要繼續(xù)下去,常與fortwohours,since1998,allthismorning,thesefewdays等表示一段時(shí)間的狀語連用。Explanation

現(xiàn)在完成進(jìn)行時(shí)的構(gòu)成:have/hasbeen＋(現(xiàn)在分詞)doing,否定形式為:have/hasnotbeendoing,一般疑問句構(gòu)成:Have/Hassb.beendoingsth.?

特殊疑問句形式(詢問持續(xù)時(shí)間長(zhǎng)短):Howlonghave/hassb.beendoingsth.?例:1).Ihavebeencleaningtheroomallthismorning.我今天一上午都在打掃房間。2).I’vebeenstudyingEnglishsinceIwas4yearsold.自從4歲起我就一直學(xué)英語。3).Hehasbeenlivinginthestreetforabout20years.他一直在這條街住了近20年了。4).Haveyoubeentalkingwithhimonthephonesince6:00p.m.?你六點(diǎn)起就一直在給他講電話？5).Howlonghasitbeenraining?雨下多久了？6).Whatbookhaveyoubeenreadingrecently?最近你在看什么書？7).Ihaven’tbeenseeingafilmforalongtime.我好長(zhǎng)時(shí)間沒看電影了。注意:for表示時(shí)間的持續(xù),后跟時(shí)間段。表示一段時(shí)間,多與帶數(shù)詞的名詞連用,謂語需用延續(xù)性動(dòng)詞。since表示“自從過去某一時(shí)間點(diǎn)以來”,后面接時(shí)間點(diǎn),強(qiáng)調(diào)動(dòng)作或狀態(tài)一直延續(xù)到現(xiàn)在,一般用現(xiàn)在完成時(shí)或現(xiàn)在完成進(jìn)行時(shí)。since后可接表時(shí)間的名詞或名詞短語,也可接一個(gè)時(shí)間狀語從句。2.Congratulationsonwinningtheskatingmarathon!

Howlonghaveyoubeenskating?(現(xiàn)在完成進(jìn)行時(shí))Howlonghaveyoubeenhere?(現(xiàn)在完成時(shí))(1)注意:一般過去時(shí)表示在過去某個(gè)時(shí)間發(fā)生的動(dòng)作或存在的狀態(tài),該動(dòng)作已結(jié)束,不強(qiáng)調(diào)同現(xiàn)在的關(guān)系;而現(xiàn)在完成進(jìn)行時(shí)表示動(dòng)作從過去開始發(fā)生一直持續(xù)進(jìn)行(到現(xiàn)在),可能仍在進(jìn)行,也可能停止了一會(huì)兒。現(xiàn)在完成時(shí)強(qiáng)調(diào)的是:i表示過去發(fā)生或已經(jīng)完成的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果,ii過去某一時(shí)間開始并一直持續(xù)到現(xiàn)在(包括“現(xiàn)在”在內(nèi))的動(dòng)作或狀態(tài),可以和表示延續(xù)的時(shí)間狀語連用。注意這三個(gè)
