4、（1）結(jié)構(gòu)由“have/has been+動(dòng)詞的現(xiàn)在分詞”構(gòu)成，表示從過去某時(shí)開始，一直持續(xù)到現(xiàn)在的動(dòng)作，可能剛剛停止，也可能還在繼續(xù)進(jìn)行。例如：We have been looking for you for an hour.我們找了你一個(gè)小時(shí)。（動(dòng)作剛停止）She has been teaching English since she graduated.她畢業(yè)后一直在教英語(yǔ)。(動(dòng)作還在繼續(xù)進(jìn)行)We have been going over maths these days.我們這些天一直在復(fù)習(xí)數(shù)學(xué)。（動(dòng)作還在繼續(xù)進(jìn)行）（2）有時(shí)現(xiàn)在完成進(jìn)行時(shí)不是指某動(dòng)作一直在不停的進(jìn)行，而是表示一直到

5、說話時(shí)為止的一段時(shí)間內(nèi)一再重復(fù)的動(dòng)作，常常帶有感情色彩。例如：She has been saying that 20 times. 這話她已經(jīng)說了20遍了。He has been calling on her several times this week. 他這個(gè)星期幾次來看他。We have been having a lot of rain recently. 最近雨水很多。（3）有時(shí)現(xiàn)在完成進(jìn)行時(shí)表示剛才或近來發(fā)生的動(dòng)作，也可表示知道說話時(shí)為止的一段時(shí)間內(nèi)發(fā)生的動(dòng)作，這一動(dòng)做到說話時(shí)已經(jīng)結(jié)束，而且一般不再繼續(xù)下去；這種用法主要表示某一動(dòng)作所產(chǎn)生的結(jié)果或?qū)ΜF(xiàn)在的影響。例如He has b
