Present Perfect Passive

Structure:

The structure of Present Perfect Passive is: Subject + has/have + been + past participle of the verb

Explanation:

In the Present Perfect Passive, the subject of the sentence receives the action that has been completed at some point in the past but is relevant to the present. It is used when the focus is on the action itself or its result, rather than who performed it. This tense connects the past action with the present state.

We use the auxiliary verb "has" or "have" depending on the subject, followed by "been," and then the past participle of the main verb. This structure emphasizes the completion of the action and its effect on the present situation, with the subject as the recipient of that action.

Examples:

Example 1 (Basic sentence):

Active: They have completed the project.

Passive: The project has been completed.

Example 2 (With an object):

Active: They have sold the car.

Passive: The car has been sold.

Example 3 (Adding more detail):

Active: The company has launched a new product this year.

Passive: A new product has been launched by the company this year.

Active: People have admired her work for decades.
