Was と Were の使い分け
過去の状態や所在を表すときは was または were を使います。基本規則を確認してから、6問の練習問題に取り組みましょう。
練習問題 ↓01 / WAS & WERE
主語と動詞の一致
I / he / she / it
was
She was at home.
you / we / they
were
They were at home.
過去の事実を述べる場合、主語が I、he、she、it および単数名詞なら was を、you、we、they および複数名詞なら were を使います。
you は単数（あなた1人）でも複数でも常に were を使います：You were right.
疑問文では was / were を主語の前に置きます：Was she at home? / Were they late? 否定文は not を加えます：was not / were not。
