    When we use the present perfect tense in speaking, we usually contract the subject and auxiliary verb. We also sometimes do this when we write.

    It has
    John has

    How do we use the Present Perfect Tense?

    کاربرد زمان حال کامل

    This tense is called the present perfect tense. There is always a connection with the past and with the present. There are basically three uses for the present perfect tense:
    همانطور که از اسم این زمان برمی آید همیشه ارتباطی بین گذشته وحال دراین زمان وجوددارد.اساسا سه کاربرد دارد.

    1. experience خاطره یا تجربه
    2. change تغییر
    3. continuing situation موقعیتی که ادامه دارد.

    1. Present perfect tense for experience

    We often use the present perfect tense to talk about experience from the past. We are not interested in when you did something. We only want to know if you did it:
    ما اغلب زمان حال کامل را درباره صحبت کردن درباره تجربه مان از گذشته بکار می بریم.مابازمان انجام عمل کاری نداریم وفقط می خواهیم بگوییم که انجام شده است.
    I have seen ET.
    He has lived in Bangkok.
    Have you been there?
    We have never eaten caviar.

    past present future

    !!!
    The action or state was in the past.
    عمل در گذشته بوده است.

    In my head, I have a memory now.
    من حالا درباره آن می دانم.


    Connection with past: the event was in the past.
    Connection with present: in my head, now, I have a memory of the event; I know something about the event; I have experience of it.
    2. Present perfect tense for change

    We also use the present perfect tense to talk about a change or new information:
    ما گذشته کامل را برای نشان دادن یک تغییر یا اطلاعات جدید بکار می بریم.
    I have bought a car.
    Last week I didn't have a car.
    هفته گذشته ماشین نداشتم.
    Now I have a car.
    حالا ماشین دارم.


    John has broken his leg.
    past present future
    + -
    Yesterday John had a good leg. Now he has a bad leg.


    Has the price gone up?
    past present future
    + -

    پلیس کیلررا گرفته است.
    past present future
    - +
    Yesterday the killer was free.
    دیروز کیلر آزادبود.
    Now he is in prison.
    حالااودرزندان است.

    Connection with past: the past is the opposite of the present.
    Connection with present: the present is the opposite of the past.
    3. Present perfect tense for continuing situation

    We often use the present perfect tense to talk about a continuing situation. This is a state that started in the past and continues in the present (and will probably continue into the future). This is a state (not an action). We usually use for or since with this structure.
    برای نشان دادن حالتی بکار میرود که در گذشته شروع شده وادامه دارد وممکن است درآینده نیز ادامه داشته باشد.ما معمولا sinceوforبااین ساختار بکار می بریم.

    He has been ill for 2 days.
    How long have you known Tara?
    past present future




    The situation started in the past. It continues up to now. (It will probably continue into the future.)

    Connection with past: the situation started in the past.
    Connection with present: the situation continues in the present.
