[yaghoob]

I don't know when should i use of have been and when use of has been?
Could you help me?

 

[probus]

Of course, "has been" is singular and "have been" is plural. The tense is called the past perfect, q.v., and is used when speaking in the present tense about an action that was completed in the past. Study up on the past perfect.

 

[tedmc]

Do you mean the present perfect, probus?

 

[yaghoob]

The strike is separate matter and road closed is separate issue too,and can i use the "protest instead strike?
