Rules of Present Perfect Continuous Tense

The Present Perfect Continuous tense is used to talk about actions or situations that started in the past and are still continuing in the present. It is formed by using the auxiliary verb "have" or "has" with "been" and the present participle form of the main verb.

Key Concepts:
1. Formation: Subject + have/has + been + present participle (-ing form of the verb)
Example: She has been working on her project for two hours.
Translation: उसने अपने परियोजना पर दो घंटे से काम किया है।

2. Use: To describe an action that started in the past and is still happening in the present.
Example: They have been living in this city since 2010.
Translation: वे 2010 से इस शहर में रह रहे हैं।

3. Use: To talk about an action that has just stopped or recently finished.
Example: I have been studying all day, and now I need a break.
Translation: मैंने पूरे दिन पढ़ाई की है, और अब मुझे आराम की जरूरत है।

Key Mistakes:
1. Confusing present perfect continuous with present continuous tense.
Example: Incorrect - I am working here for five years.
Correct - I have been working here for five years.
Translation: गलत - मैं यहां पांच साल से काम कर रहा हूँ।
सही - मैं यहां पांच साल से काम कर रहा हूँ।

2. Using the past participle form instead of the present participle form.
Example: Incorrect - She has been worked on her project.
Correct - She has been working on her project.
Translation: गलत - उसने अपने परियोजना पर काम किया है।
सही - उसने अपने परियोजना पर काम किया है।

Remember to use the Present Perfect Continuous tense when talking about ongoing actions or situations that started in the past and are still happening in the present.
