thecar.2.現在完成進行時表示過去某一動作的延續(xù)性

和重復性，并常帶有較強的感情色彩。

allthemorning/afternoon,recently等時間狀語以及由since或for引導的時間狀語連用。egI’vebeenwritinglettersallthiseveningandI’vejustfinishedthem.Shehasbeenexpectingalongdistancecallallnightlong.現在完成進行時與現在完成時1.

現在完成時通常表示動作已完成，而現在完成進行時卻不一定如此。如：Ihavelookedforasuitableschoolallaroundthecity.

（已經不找了）Ihavebeenlookingforasuitableschoolallaroundthecity.

（一直在找）2.

現在完成時通常表示反復發(fā)生的動作，可用howmanytimes詢問動作完成的次數；現在完成進行時通常表示持續(xù)不間斷的動作，一般用howlong詢問動作持續(xù)的時間。如：Howmanytimeshaveyouvisitedthemuseum?（強調動作的重復性）Howlonghaveyoubeenworkinginthecompany?

（強調動作的延續(xù)性）3.

許多靜態(tài)動詞只能用于現在完成時而不能用于現在完成進行時。如：He’salovelydog

howlonghaveyouhadhim?Theboyhasadmittedhismistake.4.already，ever，never，yet等副詞通常不用于現在完成進行時。5.現在完成時一般表示平鋪直敘；現在完成進行時含有感情色彩。試比較：IhavestudiedEnglishfor8years.Henryhasbeendoinghisworkorderly.含有贊賞表揚的意味陳述客觀事實[北京卷]Excuseme,whichmovieareyouwaitingfor?ThenewStarWars.We_____hereformorethantwohours.A.waitedB.waitC.wouldbewaitingD.havebeenwaitingD2.[江蘇卷]Dashan,who____crosstalk,theChinesecomedictradition,fordecades,wantstomixitupwiththeWestern
