**仁愛(ài)英語(yǔ)九年級(jí)現(xiàn)在完成時(shí)**

2010.09.15

現(xiàn)在完成時(shí)是由助動(dòng)詞have（has）+過(guò)去分詞構(gòu)成其否定句在Have/has后加not.一般疑問(wèn)句把have/has提到主語(yǔ)前.動(dòng)詞的過(guò)去分詞：規(guī)則變化（和過(guò)去時(shí)一樣）不規(guī)則變化：不規(guī)則變化：am/is-was-beenare-were-beenbegin-began-begunbreak-broke-brokendo-did-donedraw-drew-drawndrink-drank-drunkdrive-drove-driveneat-ate-eatenfall-fell-fallenfly-flew-flownforget-forgot-forgottengive-gave-givengo-went-gonegrow-grew-grownhide-hid-hiddenknow-knew-knownlie-lay-lainride-rode-riddenring-rang-rungshow-showed-shownsee-saw-seensing-sang-sungspeak-spoke-spokentake-took-takencome-came-comerun-ran–runbecome-became-become2。表示過(guò)去已經(jīng)開(kāi)始，持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)，也可以表示實(shí)質(zhì)可能繼續(xù)下去的動(dòng)作或狀態(tài)。通常和for（段時(shí)間）,since（點(diǎn)時(shí)間）引導(dǎo)的時(shí)間狀語(yǔ)連用.以及sofar,bynow,thesedays,inthelasttenyears等連用。Ihavebeenhereforjustovertwoyears.Hehasworkedheresince1989.從1989年，Ihaven’tseenher
