was 和 were 是 be 動詞的過去簡單式形式。I/he/she/it 要用 was，you/we/they 要用 were。

I was at school this morning. 我今天早上在學校。You were absent yesterday. 你昨天缺席。She was happy at the concert. 她在演唱會上很開心。We were excited after the game. 我們在比賽之後很興奮。Were they at school? 他們在學校嗎?

否定句 was not 和 were not 的縮寫為 wasn’t 和 weren’t，但是肯定句 was 和 were 沒有縮寫的形式。

He was sad, but she wasn’t very sad. 他很傷心，但她沒有很傷心。 Sarah and Amber were hungry, but we weren’t hungry. Sarah和Amber很餓，但我們不餓。

Was/were 是 am/is/are 的過去式形式。現在式: am/is 等於過去式: was，現在式: are 等於過去式: were。

I’m sad. -> I was sad. 我很難過。She is at school.-> she was at school. 她在學校。You are slow. -> You were slow. 你很慢。

was/were 表示過去。通常會加上過去時間: yesterday, last night, last week, two months ago 等。

He was in Europe last winter. 他去年冬天在歐洲。You were late to school yesterday. 他們昨天上學遲到。

在表達出生 born 時的 be 動詞要用was/were。be 動詞加 born 只有過去式的形式: was/were born。

 “When were you born?” “I was born in 1999.” “你何時出生?” “我出生於1999年。”
