    قاعدة If

    قاعدة If لها ثلاث حالات ..

    الحالة الأولى:

    If + Present Simple, will + infinitive.

    Ex. If he studies hard, he will succeed.

    - تستخدم لحدث مطابق للواقع, أي أن الشخص يذاكر بالفعل, و لكي نربط مذاكرته في الحاضر بالنتيجة في المستقبل نستخدم الحالة الأولى.





    الحالة الثانية:

    If + Past Simple, would + infinitive.

    Ex. If he studied hard, he would succeed.

    - تستخدم للتعبير عن إفتراض في الحاضر, أي أن الشخص لا يذاكر في الحاضر و لكننا نفترض أنه إن يذاكر في الحاضر, سوف ينجح.





    الحالة الثالثة:

    If + Past Perfect, would have + P.P.

    Ex. If he had studied hard, he would have succeeded.

    - تستخدم للتعبير عن إفتراض في الماضي, أي أن الشخص لم يذاكر في الماضي و أنه رسب. بمعنى أنه لو كان قد ذاكر لكان قد نجح.



    Exercise



    1- He studies hard. He will succeed. (Join)

    If he studies hard, he will succeed.



    2- Factories close. Many people lose their jobs. (Join using: If)

    If factories didn’t close, many people wouldn’t lose their jobs.



    3- Facories closed. Many people lost their jobs. (Join using: If)

    If factories hadn’t closed, many people wouldn’t have lost their jobs.



    ملاحظات: في الحالات الثانية و الثالثة نفترض عكس الواقع.




    Conditional Clauses
    * Formation : The three principal sentence patterns using ( if ) or ( unless ) are :

    - If ( Present simple ),…will / shall + infinitive.

    - If ( Past simple ),…would + infinitive.

    - If ( Past perfect ),…would + have + P.P.



    N.B. - If the if-clause is in the present simple, the result clause will also be in the

    present simple, provided that the sentence is expressing a fact.



    - For unlikely or improbable conditions, use ( were ) instead of (was).

    - Sometimes conditions are expressed by inversion with the use of

    ( Were / Had / Should ) + Subject…
