And the 3rd one is (OBJECT) (Object is that the one that is being worked on).

When you will say any sentence and you will add Had been and Verb's ING form on that sentence so it will show that you are talking about that action which Had been continue in past for along time.

 Since/For:

Since/For we use these two words for showing the time For Ex: You are doing something for long period of time so you will add since/for on that sentence Now the question is where do we use since and where do we use For:

Since: Since we use for showing that time that can not be changed LIKE: If I say that. He had been watching T.V since 1  O'clock Now as long as He had been watching T.V But 1 o'clock will not be changed because From when had he been watching T.V.

For: For we use for showing that time that can be changed LIKE: If I say that He has been watching T.V for 2 hours Now if He will keep watching T.V 1 more hour so the time will be changed How because first of all we said that He has been watching T.V for 2 hours  Now if He will keep watching T.V 1 more hour so we will say that He has been watching T.V for 3 hours look the time has changed in first sentence we said 2 hours and now we are saying 3 hours so For we use for showing the time that can be changed.
