Unit 3 be動詞 一般動詞的過去式 YouTube
1. be動詞的過去式 => was/were
am/is => was, are => were.
- 過去式的be動詞表示"過去時間中發生的狀態"
使用過去式, 代表現在已經不是該狀態了.
時間副詞的改變,動詞也要跟著改
(例) He is busy now.
過去式: He was busy then.(那時)
(例) My parents are at home now.
過去式: My parents were at home yesterday. 現在一定不在家 - be動詞(過去式)的否定句 => 主詞 + was/were + not
縮寫 wasn’t/weren’t
(例) Mr. Brown was a vet.
否定句: Mr. Brown was not a vet.
(例) Joe and Brian were in the living room at that time.
否定句: Joe and Brian were not in the living room at that time. - be動詞(過去式)的疑問句
肯定句: 主詞 + was/were ~
疑問句: Was/Were + 主詞 ~
(例) Wendy was in the seventh grade last year.
疑問句: Was Wendy in the seventh grade last year?
答句: Yes, 主詞 + was/were. No, 主詞 + was/were not
(例) Were you a pianist?
答句: Yes, I was. / No I wasn’t.
2. 一般動詞的過去式 => 規則變化/不規則變化
- 原形動詞 + ed.
(例) helped, spelled, wanted. - 原形動詞字尾有e + d.
(例) love -> loved, dance -> danced. - 原形動詞為子音+短母音+子音, 重複字尾加ed
(例) stop -> stopped, plan -> planned. - 原形動詞字尾為子音 + y. => 去 y + ied.
(例) study -> studied, cry -> cried. - 不規則變化
(例) eat -> ate, read -> read, ride ->rode, come -> came, go -> went…
(例) I walk to school every day.
過去式: I walked to school yesterday.
(例) Mother goes to a supermarket every morning.
過去式: Mother went to a supermarket yesterday morning. - 主詞為第三人稱單數時, 過去式動詞不需要+s
- 一般動詞 (過去式) 的否定句 => 需用助動詞did
肯定句: 主詞 + 一般動詞 (過去式)
否定去: 主詞 + did not (didn’t) + 原形動詞
(例) He called you last night.
否定句: He didn't call you last night.
(例) My sister and I watched TV all day yesterday.
否定句 My sister and I didn’t watch TV all day yesterday. (did not all => 並非) - 比較: 否定句 (過去式)

一般動詞:
