“I was tired yesterday.” “They were so happy.” 이 두 문장에서 was와 were는 왜 다를까요? be동사의 현재형은 am/is/are 세 종류이지만, 과거형은 was/were 딱 두 종류뿐입니다. 많은 분들이 언제 was를 쓰고 언제 were를 쓰는지 헷갈려 합니다. 고딸영문법 2권 Unit1에서는 이 두 가지 규칙을 3분 만에 깔끔하게 정리합니다. 딱 두 가지만 기억하면 was/were 완전 정복입니다.

💡 실용 팁
암기 공식 하나로: “am/is → was, are → were” — 이 공식 하나면 충분
you는 단수지만 were: “You was…” (✗) → “You were…” (✓) — 유일한 예외 기억
단답형은 주어 + was/were만: “Were you hungry?” → “Yes, I was.” 뒤 내용 생략 가능
축약형 적극 활용: wasn’t / weren’t는 회화에서 자주 사용
명사 주어는 수 확인: the dog(단수)→was / the dogs(복수)→were
어제 하루 일기 연습: “I was ___ . It was ___ . My friend was/were ___.” 세 문장으로 시작
⚠️ 주의할 점
“You was…” (✗) → “You were…” (✓) — you는 단수처럼 보여도 항상 were
“I were…” (✗) → “I was…” (✓) — I는 항상 was (가정법 If I were you… 예외)
“Did she was…?” (✗) → “Was she…?” (✓) — be동사 의문문에는 do/did 사용 금지
“No, I was not.”“No, I wasn’t.” — 부정 단답형은 축약형이 자연스러움
과거 의미 없이 was/were 사용 금지: 현재 상황에 was/were 쓰면 완전히 다른 의미 → 시제 항상 확인

be동사 과거형, 딱 두 가지면 끝입니다. I/He/She/It이면 was, You/We/They이면 were. am/is는 was로, are는 were로. 오늘 배운 내용으로 어제 하루를 영어로 써보세요. “I was at home. It was a good day. My friends were busy.” 이 세 문장이 완벽한 연습의 시작입니다.
