In the english grammar, “Tense” is a part of functional grammar. And, we know that it is too dynamic and confusing to grasp perfectly. In this blog, I am going to explain the use and importance of present perfect continuous tense and its major difference with simple past and present perfect tense.
Use of present perfect continuous tense
It is used to describe the action began in the past; but, it is yet to be completed. Clearly, its beginning has already done; but, it is still continue in the present tense.
•I have been writing my assignment since 6 A.M.
•We have been planning to launch a new plan since our last meeting.
•They have been thinking to visit Ajanta Caves since 10th standard.
•She has been preparing for her exam for two years.
•He has been working there for a decade.
•He has been living here for five years.
Adverbial of times or times expression
In this type, point of time and period of time is mentioned to delineate the range of action in the given time. Generally, for this, “Since and For” are preferred most of the time.
On the other hand, in case of perfect present, though the action begins in the past, it is totally completed in the present at the time of expression.
•I have already completed my assignment.
•We have decided to launch new plan of action.
•They have visited Ajantha Caves twice this year.
•She has cracked her exam with distinction.
•She has achieved this feat many times in her life.
•He has already finished his job.
•He has beautifully played in the final match.
•It has rained heavyily since morning.
Domain of present perfect continuous tense
In simple past, beginning, as well as completion happens in the past tense. So, this is very important to notice that simple past, present perfect, and present perfect continuous tense are used to describe the range and extension of occurred action.
•I completed my assignment yesterday.
•We visited the Ajanta Caves in last week.
•He finished his job in last month.
•She received your gift day before yesterday.
Besides, present continuous tense is used to express the action happening at the time of expression. Therefore, the ambit of present continuous tense is only for a moment of expression.
•Don’t ask me for help. I am writing my assignment now.
•Don’t be so panic. I am just coming.
•OK, we are going to visit Ajanta Caves tomorrow.
Definitely, comparative study of simple past, present continuous, present perfect, and present perfect continuous tense is quiet effective to eradicate confusion. No doubt, this is the best way to bring more clarity of highly useful part of english grammar.
