Unit 3 be動詞與一般動詞過去式

1. （選擇題）「He is busy now.」若將時間副詞改為那時 (then)，句子應改為什麼？

He was busy then. He did busy then. He were busy then.

❌ 答錯了！主詞 He 為第三人稱單數，現在式 be 動詞 is 對應的過去式為 was。

✨ 答對了！He was busy then. 表示過去的狀態。

2. （填充題）請填入正確的 be 動詞過去式：My parents ______ at home yesterday.

❌ 答錯了！主詞 My parents（我父母）為複數名詞，必須搭配過去式 be 動詞 were。

✨ 答對了！複數名詞對應 were。

3. （填充題）將括號內的一般動詞改為過去式規則變化：The car ______ (stop) at the corner two minutes ago.

❌ 答錯了！stop 的字尾是「單短母音 + 單子音」，必須先重複字尾 p 再加 ed → stopped。

✨ 答對了！重複字尾的 stopped 才是正確答案。

4. （填充題）將動詞改為過去式規則變化：He ______ (study) all day yesterday morning.

❌ 答錯了！study 字尾為「子音 + y」，在過去式規則中需去 y 加 ied → studied。

✨ 答對了！就是 studied。

5. （選擇題）將肯定句「He called you last night.」改為否定句，何者正確？

He wasn't call you last night. He didn't called you last night. He did not call you last night.

❌ 答錯了！答案是 C。一般動詞否定需引進助動詞 did not (didn't)，且後方的動詞必須回復成「原形動詞 call」。

✨ 答對了！助動詞 did not 加上原形動詞 call 完全正確。

6. （填充題）填入不規則動詞過去式：Mother ______ (go) to a supermarket yesterday morning.

❌ 答錯了！動詞 go 的過去式為完全不規則變化的 went。

✨ 答對了！go 的過去式就是 went。

7. （選擇題）「Were you a pianist last year?」最標準正確的簡答句是？

Yes, I was. Yes, I did. Yes, you were.

❌ 答錯了！答案是 A。問句問「你去年是鋼琴家嗎？」，回答要用第一人稱「是的，我是」→ Yes, I was.

✨ 答對了！以 be 動詞過去式提問，亦以 be 動詞過去式 was 回答。

8. （選擇題）將肯定句「Grace wrote a letter to David.」改為疑問句，何者完全正確？

Did Grace wrote a letter to David? Did Grace write a letter to David? Was Grace write a letter to David?

❌ 答錯了！答案是 B。一般動詞過去式疑問句引進助動詞 Did，後半段的 V 必須回復原形動詞 write。

✨ 答對了！Did 後面完美搭配原形動詞 write。

9. （選擇題）將大考陷阱題「He did his homework.」改為疑問句，正確答案是？

Did he his homework? Was he did his homework? Did he do his homework?

❌ 答錯了！答案是 C。這裡的 did 是指「做（一般動詞）」，提問時首位放助動詞 Did，原本的動詞要恢復原形 do。

✨ 答對了！經典陷阱題：助動詞 Did + 主詞 + 原形動詞 do。

10. （填充題）將肯定句改為否定句：My sister and I watched TV. → My sister and I ______ ______ TV.

❌ 答錯了！過去式否定使用 didn't 加上原形動詞 watch → didn't watch。

✨ 答對了！didn't watch 才是完全正確的否定結構。
