شرطی نوع سوم (Third Conditional) برای صحبت درباره موقعیتهای غیرواقعی در گذشته استفاده میشود. در این نوع شرطی، درباره اتفاقی صحبت میکنیم که در گذشته رخ نداده است و سپس نتیجهای را بیان میکنیم که اگر آن اتفاق رخ داده بود، احتمالاً به وجود میآمد. به زبان ساده، مفهوم شرطی نوع سوم این است: اگر آن اتفاق در گذشته رخ داده بود، این نتیجه هم (در همان گذشته) اتفاق میافتاد. اما چون گذشته قابل تغییر نیست، هم شرط و هم نتیجه فقط فرضی هستند.
If I had studied harder, I would have passed the exam.
منظور این است که من به اندازه کافی درس نخواندم و در نتیجه قبول نشدم. حالا فقط در حال تصور کردن نتیجهای هستم که میتوانست در گذشته اتفاق بیفتد.
چه زمانی از شرطی نوع سوم استفاده میکنیم؟
جملات شرطی نوع سه را معمولاُ در موقعیتهای زیر به کار میبریم:
صحبت درباره اتفاقهایی که در گذشته رخ ندادند
رایجترین کاربرد شرطی نوع سوم، صحبت درباره شرایطی است که در گذشته اتفاق نیفتادهاند.
If I had left earlier, I would have caught the train.
If she had called me, I would have answered.
If they had invited us, we would have gone.
ابراز پشیمانی
گاهی از شرطی نوع سوم برای بیان پشیمانی از یک تصمیم یا اتفاق در گذشته استفاده میکنیم.
If I had listened to my parents, I would have made a better decision.
If we had booked earlier, we would have paid less.
If he had studied more, he would have passed the exam.
سرزنش یا انتقاد
گاهی میخواهیم نشان دهیم که اگر کسی کار دیگری انجام داده بود، نتیجه متفاوتی به دست میآمد.
If you had been more careful, you wouldn’t have broken your phone.
If they had followed the instructions, they wouldn’t have made that mistake.
If she had arrived on time, we wouldn’t have missed the meeting.
تحلیل اتفاقهای گذشته
گاهی پس از پایان یک اتفاق، درباره نتیجههای احتمالی آن فکر میکنیم و بررسی میکنیم که اگر شرایط متفاوت بود، چه اتفاقی میافتاد.
If we had taken another road, we would have arrived sooner.
If the weather had been better, we would have gone hiking.
If I had accepted that job, my life would have been different.
تصور کردن گذشتهای متفاوت
گاهی فقط میخواهیم گذشته را به شکل دیگری تصور کنیم.
If I had been born in another country, I would have learned a different language.
If we had met earlier, we would have become close friends.
If she had chosen another university, she would have studied medicine.
ساختار شرطی نوع سوم
ساختار اصلی شرطی نوع سوم به شکل زیر است:
If + Past Perfect, would have + قسمت سوم فعل (Past Participle)
در بخش شرط از Past Perfect استفاده میکنیم، زیرا درباره یک اتفاق فرضی در گذشته صحبت میکنیم. در بخش نتیجه نیز معمولاً از would have + Past Participle استفاده میشود تا نتیجه فرضی آن اتفاق را بیان کنیم.
If I had known the answer, I would have told you.
If she had arrived earlier, she would have seen him.
If they had saved more money, they would have bought a bigger house.
مثل سایر جملههای شرطی، میتوان جای دو بخش جمله را نیز عوض کرد.
I would have told you if I had known the answer.
She would have seen him if she had arrived earlier.
They would have bought a bigger house if they had saved more money.
اگر جمله با If شروع شود، بعد از بخش شرط از ویرگول استفاده میکنیم. اما اگر جمله با بخش اصلی شروع شود، نیازی به ویرگول نیست.

خلاصه
شرطی نوع سوم برای بیان شرایط فرضی و غیرواقعی در گذشته استفاده میشود. در این ساختار، بخش شرط با Past Perfect و بخش نتیجه معمولاً با would have + Past Participle ساخته میشود. از این نوع شرطی برای بیان پشیمانی، انتقاد، تحلیل اتفاقهای گذشته و تصور کردن نتیجههای متفاوت برای رویدادهایی استفاده میکنیم که در گذشته رخ دادهاند یا رخ ندادهاند.
