برای چیزی که قبلاً اینطوری بود ولی دیگه نیست، بگو used to + فعل ساده.
used to + فعل ساده
I used to play tennis. (but I stopped)
Amina used to live near the harbor. (now she lives downtown)
We used to walk to school every day.
Not "I use to play tennis." — say "I used to play tennis.". اینجا -d داره: used to. یعنی قبلاً انجامش میدادی، ولی نه الان.
خودت امتحان کن: Amina ___ live near the harbor, but now she lives downtown. (used to / use to / uses to) جواب: used to — برای چیزی که قبلاً اینطوری بود و بعد عوض شد، از used to استفاده کن، با اون -d. «Use to» (بدون -d) و «uses to» اینجا شکلِ گذشته نیستن: she used to live there.
didn't use to
برای گفتن اینکه یه چیزی قبلاً اینطوری نبود، بگو didn't use to + فعل ساده. بعد از didn't، اون -d رو بنداز: میشه use to، نه «used to».
I didn't use to like coffee. (now I do)
She didn't use to study hard.
We didn't use to have a car.
Not "I didn't used to like coffee." — say "I didn't use to like coffee.". بعد از didn't، هیچ -d نیست: didn't use to.
خودت امتحان کن: I ___ like coffee, but now I drink it every day. (didn't use to / didn't used to / don't use to) جواب: didn't use to — کلمهها درستن، ولی بعد از didn't هیچ -d نیست: didn't use to (نه «didn't used to»). و برای گذشته به didn't نیاز داری، نه «don't».
Did you use to ...?
برای سؤال، با Did + شخص + use to + فعل ساده شروع کن. بازم، بعد از Did، میشه use to بدون -d.
Did you use to play tennis?
Did she use to live here?
Where did you use to work?
خودت امتحان کن: ___ you use to play tennis? (Did / Do / Were) جواب: Did — برای پرسیدن دربارهی گذشته، با Did شروع کن: Did you use to play tennis? «Do» برای الانه، و «Were» برای اینه که کسی چی بود، نه اینکه چی کار میکرد.
خودت امتحان کن: She ___ smoke, but she ___ exercise much — she never went to the gym back then. (used to … didn't use to / use to … didn't used to / used to … didn't used to) جواب: used to … didn't use to — بهتنهایی اون -d رو نگه میداره: used to smoke. ولی کنارِ didn't، اون -d میره: didn't use to. اون -d توی جملهی ساده هست و بعد از did/didn't میره.
