現(xiàn)在完成時(shí)表示 ___其結(jié)構(gòu)形式為 。
Step 2: Grammar: 現(xiàn)在完成進(jìn)行時(shí)
A. 現(xiàn)在完成進(jìn)行時(shí)由“has/have been+現(xiàn)在分詞”構(gòu)成，其主要用法如下：
（1）表示動(dòng)作從過(guò)去某一時(shí)間開(kāi)始一直延續(xù)到現(xiàn)在或離現(xiàn)在不遠(yuǎn)的時(shí)間，這個(gè)動(dòng)作可能已經(jīng)結(jié)束，也可能還在進(jìn)行。這種時(shí)態(tài)多用于持續(xù)性動(dòng)詞，如：learn, lie, stay, sit, wait, stand, study等。常和all the time, this week, all night, recently等狀語(yǔ)及since和for所引導(dǎo)的時(shí)間狀語(yǔ)或從句連用。
I have been fixing the fridge all the morning.（動(dòng)作可能持續(xù)下去）
（2）表動(dòng)作的重復(fù): 有時(shí)現(xiàn)在完成進(jìn)行時(shí)表示的動(dòng)作并不是一直在不停的進(jìn)行，而是在斷斷續(xù)續(xù)的重復(fù)。
You have been saying that you can succeed for five years.
（3）用于得出結(jié)論
You look thin and tired. You have been working too hard.
你看起來(lái)又瘦又累，你近來(lái)工作一定很辛苦。
（4）表示感情色彩
現(xiàn)在完成進(jìn)行時(shí)有時(shí)帶有強(qiáng)烈的表?yè)P(yáng)或厭惡等感情色彩。
Too much has been happening today. 今天真是一個(gè)多事的日子。
B. 現(xiàn)在完成時(shí)與現(xiàn)在完成進(jìn)行時(shí)的區(qū)別
（1）完成性
現(xiàn)在完成時(shí)的已完成用法強(qiáng)調(diào)動(dòng)作的完成，而現(xiàn)在完成進(jìn)行時(shí)側(cè)重于未完成。
翻譯：I have read this book.
I have been reading this book.
(2)動(dòng)作的持久性: 現(xiàn)在完成進(jìn)行時(shí)更強(qiáng)調(diào)動(dòng)作延續(xù)時(shí)間的長(zhǎng)久性。
翻譯：I have stayed in London for six weeks.________________________________
I have been staying in London for six weeks.___________________________
(3)動(dòng)作的頻繁性
現(xiàn)在完成時(shí)同某些頻度副詞或數(shù)詞連用時(shí)，表示反復(fù)的但可能有間斷的動(dòng)作，現(xiàn)在完成進(jìn)行時(shí)可以表示斷斷續(xù)續(xù)的重復(fù)的動(dòng)作，但不能同表示具體次數(shù)和具體數(shù)字的詞連用。
翻譯：I’ve posted a dozen postcards,but received none.________________________
I’ve been posting postcards since early December.___________________________
判斷正誤：I have been reading this book several times.（ ）
I have read this book several times.（ ）
（4）感情色彩
現(xiàn)在完成時(shí)感情色彩不濃，而現(xiàn)在完成進(jìn)行時(shí)帶有強(qiáng)烈的感情色彩。
You have been talking too much and doing so little._________________________
