（一）含义：1.动作自过去某时开始，一直延续到现在，而且还将持续下去；2.动作从过去某时开始，一直延续到说话时刻，可能刚结束。

（二）现在完成进行时用法

1.

用法一

叙述某一动作从过去开始一直持续到现在，仍在继续之中或刚刚停止。经常与for,since,all morning/day/week等用在一起。

例：The telephone has been ringing for almost a minute. Why doesn’t someone answer it? 2.用法二

叙述“最近”（lately，recently）一直从事的工作或活动。

例：What’s the matter? Your eyes are red .What have you been doing recently? 3. 用法三

表示重复动作。有时现在完成进行时所表示的动作并不是一直不停地进行，而是在断断续续地重复。

例：I have been knocking .I don’t think anybody is in.

4.用法四

表示“刚才、近来”发生的动作，一般不再继续。此时一般通过上下文的语境进行判断。

My hands are dirty. I have been paining the door. 三．链接：现在完成时

含义：一种表示过去发生并且已经完成的动作对现在造成的影响或后果；另一种表示过去某一时间开始并一直持续到现在，并且有可能还会持续的动作或状态。即表示影响、结果或持续。

基本结构:___________(主动)

________________(被动) 例：He has left the city. He has taught in our school for 20 years. 四．比较现在完成时与现在完成进行时

（一）相同点：两者都可以表示从过去某一时刻开始一直延续到现在的动作;也都可以表示一段时间内进行的动作。这时可以互换。如：I have worked in this school since 2005. I have been working in this school since 2005. （二）不同点(主要区别)：

1.现在完成时表示已经完成的动作或状态，常与already（已经）或ever(曾经)连用。而现在完成进行时则不能与之连用。

如：She is the most beautiful girl I have ever seen. 2.含义上。现在完成时强调动作的结果，后者强调过程。如：

We have cleaned the house.You may come in now. We are very tired. We have been cleaning the house.
