Was / Were (A1)

I, he, she, it 用 was。

I / he / she / it: was

• I was at home.
• He was tired.
• It was cold.
• Not "I were at home." — say "I was at home.". 用 I 的时候，过去式是 was，不是 were。
• 试一试: Yesterday it ___ very cold. (was / were / is) 答案: was — it 要用 was，不是 were。（"Is" 是现在时，"yesterday" 告诉你这是过去。）所以是：it was cold.

You / we / they: were

you, we, 和 they 用 were。

• You were late.
• We were happy.
• They were at school.
• Not "They was at school." — say "They were at school.". 用 they 的时候用 were，was 只用于 I、he、she、it。
• 试一试: Amina and Hiroshi ___ at Magaff Library. (were / was / are) 答案: were — Amina and Hiroshi = they，所以要用 were，不是 was：They were at Magaff Library.

was 还是 were？

每次用之前先问一句：主语是谁？ I/he/she/it → was。you/we/they → were。

• He was here. / They were here.
• I was tired. / We were tired.
• Not "He were here. / They was here." — say "He was here. / They were here.". 由主语决定：一个人（I/he/she/it）用 was，you/we/they 用 were。
• 试一试: Lars ___ at the park, but his friends ___ at the gym. (was … were / were … was / was … was) 答案: was … were — Lars = he → was。His friends = they → were。每一个都由“说的是谁”来决定。

否定句：wasn't / weren't

在 was 或 were 后面加 not：wasn't（I/he/she/it），weren't（you/we/they）。

• I wasn't hungry.
• He wasn't there.
• They weren't happy.
• Not "I not was hungry." — say "I wasn't hungry.". not 要放在 was 后面，不是前面。
• 试一试: She ___ at home last night. (wasn't / weren't / not was) 答案: wasn't — She 用 was，所以否定式是 wasn't（不是 weren't），not 放在后面：She wasn't at home.

疑问句：Was / Were 放最前

要提问，就把 Was 或 Were 放在那个人前面。

• Was she at home?
• Were you late?
• Was it cold?
• Not "You were late? (asking)" — say "Were you late?". 疑问句里，were 放最前面，然后才是主语。
• 试一试: ___ you late for class? (Were / Was / Did) 答案: Were — You 用 were，疑问句里它放最前面：Were you late?（Was 是给 I/he/she/it 用的。）
• 试一试: Remember: who is it? Mei ___ at the cooking class. (was / were / are) 答案: was — Mei = she → was。（这是核心判断：I/he/she/it → was，you/we/they → were。）
