英語知識(shí)點(diǎn)是學(xué)習(xí)英語的關(guān)鍵。我們要對(duì)它格外重視。因此小編為大家整理了這篇2013高中英語知識(shí)點(diǎn)復(fù)習(xí)之現(xiàn)在完成進(jìn)行時(shí)以供大家參考。

一、現(xiàn)在完成進(jìn)行時(shí)語法概述

現(xiàn)在完成進(jìn)行時(shí)表示某動(dòng)作從過去某個(gè)時(shí)間開始，一直延續(xù)到現(xiàn)在，并且還有可能持續(xù)下去。如：

Those cats have been screaming for hours. 那些貓叫了半天了。

We have been waiting for him for two hours. 我們等他等了兩個(gè)小時(shí)。

The dollar has been climbing steadily all week. 整個(gè)星期美元一直在穩(wěn)步增值。

二、現(xiàn)在完成進(jìn)行時(shí)的結(jié)構(gòu)

現(xiàn)在完成進(jìn)行時(shí)由“have / has been + 現(xiàn)在分詞”構(gòu)成。如：

Sales have been dropping off badly. 銷售量一直減少得很厲害。

I have been waiting for an hour and a half. 我一直等了一個(gè)半小時(shí)了。

We’ll have been living here for two years by next Sunday. 到下星期日，我們?cè)谶@里就住了整兩年了。

三、現(xiàn)在完成進(jìn)行時(shí)有哪些主要用法

1. 表示“持續(xù)”：

即表示一個(gè)從過去某時(shí)開始一直持續(xù)的動(dòng)作，這動(dòng)作可能剛剛停止，也可能還在進(jìn)行。如：

She has been pruning the roses. 她一直在修剪玫瑰。

The children have been having a lot of fun. 孩子們一直玩得很開心。

It has been raining since last Sunday. 自上周星期日以來就一直在下雨。

He's been watching television all day. 他看了一天電視了。

2. 表示“重復(fù)”

即表示在一段持續(xù)的時(shí)間內(nèi)動(dòng)作的多次重復(fù)，而這個(gè)重復(fù)的動(dòng)作在說話時(shí)并不一定在進(jìn)行。如：

We’ve all along been making mistakes like this. 我們一直犯這樣的錯(cuò)誤。

Jim has been phoning Jenny every night for the past week. 一星期以來吉姆每天晚上給詹妮打電話。3. 現(xiàn)在完成進(jìn)行時(shí)有時(shí)表示根據(jù)直接或間接的證據(jù)得出的結(jié)論。如：

She is very tired. She's been typing letters all day. 她很累了，她整天都在打信件。

Her eyes are red. She has been crying. 她眼睛紅了，她一直在哭。

四、與現(xiàn)在完成進(jìn)行連用的主要時(shí)間狀語

現(xiàn)在完成進(jìn)行時(shí)所用的時(shí)間狀語：all day / month; this month / week / year; these days; recently / lately; in the past few + 時(shí)間段; since +時(shí)間點(diǎn); for + 時(shí)間段，等等。如：
