现在完成进行时的意义

2).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。

例句

2

They have been building the bridge for two month. He has been playing basketball since he was ten. Maggie has been teaching English for ten years.

翻译

他已经踢了八年足球了。

He has been playing football for eight years. 自从今年开始我一直坚持早起。

I have been getting early since this year.

从昨天晚上以来我就一直告诉他别去。

I have been telling him not to go since last night.

3.How to distinguish the Present Perfect Tense and Present Perfect Continuous Tense 现在完成时与现在完成进行时的区别

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。

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。

相同点：1）谓语动词都是延续性的，如live，learn，study，wait,work,rain等。

2）都与“一段时间”连用。

例句

I have been learning/learned English for ten years. I have been living/lived here since three years ago.

不同点：

1）现在完成时——结果，现在完成进行时——过程。

2）现在完成进行时带有一定的感情色彩。

例句

3

He has sung for two hours. He has been singing for two hours.

Step 4 Practice 1.Role play Students have a role play game in groups. 2.Writing Write a small composition about your own life, including one or two sentences using the present perfect continuous tense.
