Grammar

Present Perfect Simple & Present Perfect Continuous

Present Perfect Continuous Tense is used to express an action which started before now ( or in the past ) and has continued up until now ( or into the present ) .

• The action may not be finish at that time. This action may still be continuing or may have just finished.

• In such sentences, Present Perfect Continuous Tense emphasizes the process or the duration of the event or state. The tense connect the past with the present.

Past Perfect Continuous Tense is used to express a past action which started in the past and continued to happen after another action or time in the past.

• ( In such sentences, Past Perfect Continuous Tense tell us “how long the action had continued” or ” the duration of the action” is emphasized more in this tense. Namely, Past Perfect Continuous Tense tells us that an event happened and continued for a certain period of time in the past, not in the present)

Shortly we can say;

• The Past Perfect Continuous Tense is used in the same way as the Present Perfect Continuous Tense, but it refers to a time in the past. On the other hand, Present Perfect Continuous Tense refers to the time in the present ( now ).
