现在完成进行时的结构1

现在完成进行时由“have / has been + 现在分词”构成。如：

Sales have been dropping off badly. 销售量一直减少得很厉害。

I have been waiting for an hour and a half. 我一直等了一个半小时了。

We’ll have been living here for two years by next Sunday. 到下星期日，我们在这里就住了整两年了。

现在完成进行时与现在完成时的区别2

1.现在完成时强调动作的完成，而现在完成进行时强调动作的延续，因此，表示动作的完成，只能用现在完成时，而不能用现在完成进行时。如：

He has changed his idea. 他改变了想法。(from

2.在表示动作的延续时，虽然既可用现在完成时，也可用现在完成进行时，但现在完成进行时强调动作的进行。因此在需要明确表示动作还要持续下去时，应用现在完成进行时。如：

We have been studying here for two years. 我们在这儿已经学习了两年了。

3. 在许多情况下，现在完成时表示动作已经完成，而现在完成进行时却并非如此。如：

He has cleaned the window. 他把窗户擦干净了。(动作已完成)

He has been cleaning the window. 他一直在擦窗户。(动作不一定完成)

4. 有些静态动词只能用于现在完成时，一般不能用于现在完成进行时。如：

I’ve known him for many years. 我认识他有许多年了。

The war has lasted for a long time. 这场战争持续了很长时间。

5. 有少数动词(如live, work, teach, study等)用两种时态都可以，意思差别不大。如：

I’ve lived [been living] here for 30 years. 我在这儿住了30年了。

How long have you worked [been working] here? 你在这里工作多久了？

6.现在完成时与现在完成进行时的相通性：在表达一个从过去开始而现在仍在继续或刚刚结束的动作时，某些动词既可以用现在完成时，也可以用现在完成进行时，如expect, hope, learn, lie, live, look, rain, sleep, sit, snow, stand, stay, study, teach, wait, want, work等。如：

你学习英语多久了？

正：How long have yon learnt English?

正：How long have you been learning English?

他已经睡了十个小时了。

正：He has slept for ten hours.

正：He has been sleeping for ten hours.

现在完成进行时有哪些主要用法3

1. 表示“持续”：

2. 表示“重复”

即表示在一段持续的时间内动作的多次重复，而这个重复的动作在说话时并不一定在进行。如：

We’ve all along been making mistakes like this. 我们一直犯这样的。错误。

Jim has been phoning Jenny every night for the past week. 一星期以来吉姆每天晚上给詹妮打电话。
