表示從過去已經(jīng)開始持續(xù)到現(xiàn)在的動作或狀態(tài)，可以和表示“從過去某一時刻延續(xù)到現(xiàn)在的一段時間狀語”連用，如“for+段時間”、“since+過去點時間”、“since+過去時的從句”、“since+一段時間+ago”。且for與since引導(dǎo)的時間狀語可以相互轉(zhuǎn)換?，F(xiàn)在完成時for和since在現(xiàn)在完成時中的應(yīng)用for與since都能與現(xiàn)在完成時連用，但區(qū)別較大：（1）for后須接“時間段”

HehasstudiedEnglishforfiveyears.

他學(xué)英語5年了。（2）since后須接“時間點”

HehasstudiedEnglishsince1999.

他從1999年開始學(xué)英語。（3）二者可以轉(zhuǎn)換

for+一段時間=since+一段時間+agoHehasbeenhereforfiveweeks.=Hehasbeenheresincefiveweeksago.

他到這兒已經(jīng)有五個星期了。e.g.Myunclehasworkedatthisfactory

這本書你買多久了?—Foraweek./Sinceaweekago.

買一周了。此種用法中表示持續(xù)性的動作或狀態(tài)的

動詞必須是延續(xù)性動詞(否定句除外)。句中動詞的特點如何區(qū)分非延續(xù)性動詞(瞬間動詞）與延續(xù)性動詞（持續(xù)性動詞）？表示短暫性(瞬間性)的動詞在現(xiàn)在完成時的句中不能和一段時間連用.短暫性的動詞如：come，go，join，leave，buy,die等，在完成時態(tài)中不能與for,since短語或Howlong等引起的時間狀語連用。Let’schant!

瞬間動詞動作快，for和since時間段，不能相連需轉(zhuǎn)化，buy要變身成have,

begin就是beon,leave就是beaway,

finish就是beover,sleep就是beasleep,

die就是bedead,open就是beopen1.轉(zhuǎn)換為相應(yīng)的延續(xù)性動詞，用于現(xiàn)在完成時。
