Present Perfect Continuous

 

We use the Present Perfect Continuous to show that something started in the past and continues in the present.

 

He has been studying for 5 hours

I have been working as an Engineer since 2010

 

We use this tense also to talk about actions that began in the past and have recently stopped.

 

I have been waiting for you for half an hour

 

We use this tense when an action or situation is temporary.

 

I have been living in London for two months.

I have been working as a Network Engineer for last few weeks

 

 

 

For and Since

 

Since and for are very common time expressions used with the Present Perfect Continuous.

 

We use for with a period of time, for example:

 

I have been living here for 20 years.

 

 

When talking about a starting point, we use since, for example:

 

I have been living here since 1960.
