構(gòu)成肯定句：主語+have/has+been+動詞-ing形式…否定句：主語+have/has+not+been+動詞-ing形式…疑問句：Have/Has+主語+been+動詞-ing形式…疑問詞+have/has+(主語+)been+動詞-ing形式...Ihavebeenworkingherefor5years.

Whathaveyoubeendoingthesedays

用法表示動作從過去某一時間開始一直持續(xù)到現(xiàn)在，并且還將持續(xù)下去。Tomisill.He'sbeenlyinginbedforthreeweeks.

表示在說話時刻之前剛剛結(jié)束的動作。Wehavebeenwaitingforyouforhalfanhour.

表示到說話時為止的一段時間內(nèi)一再重復(fù)的動作，通常帶有感彩。Toomuchhasbeenhappeningtoday.

某些不具延續(xù)性含義的動詞，如come,go,marry,die,finish等，不適用于現(xiàn)在完成進行時。

常搭配的時間狀語allthistime,thisyear/season/month/week,allthemorning,allnight,“for+一段時間”,“since+時間點”,thesefewdays等。Whathaveyoubeendoingallthistime

Jackhasbeenscoringplentyofgoalsthisseason.

IhavebeenlearningEnglishforthreeyears.

與現(xiàn)在完成時的區(qū)別現(xiàn)在完成進行時強調(diào)在一段時間內(nèi)某項活動的持續(xù)性，強調(diào)動作本身；而現(xiàn)在完成時強調(diào)動作產(chǎn)生的結(jié)果或影響。I'vebeenpaintingthedoorthismorning.

Ihavepaintedthedooranditlookslikeanewone.

現(xiàn)在完成進行時有時含有明顯的感彩，而現(xiàn)在完成時往往只說明一個事實，一種影響或結(jié)果，沒有感彩。Whohasbeeneatingmyapples

Whohaseatenmyapples

許多靜態(tài)動詞（know,be,have,find,understand等）通常用于現(xiàn)在完成時而不用于現(xiàn)在完成進行時。We'veknowneachothersincechildhood.
