第一步：找主要動詞

原句：

Allen looked upset when he gazed at the picture, ________?

主要子句是：

Allen looked upset

  • 主詞：Allen
  • 動詞：looked（看起來）
  • looked 在這裡是 一般過去式，不是 be 動詞。

後面的

when he gazed at the picture
只是時間副詞子句，不影響附加問句（tag question）。

第二步：附加問句規則

規則：

  • 前面肯定句 → 後面否定問句
  • 前面否定句 → 後面肯定問句

所以：

Allen looked upset, didn't he?

因為 looked 是一般動詞，所以要用助動詞 did。

第三步：為什麼不是 was he / wasn't he？

很多人會被 looked upset 騙到。

比較：

✅ He was upset.
→ wasn't he?

✅ He looked upset.
→ didn't he?

因為：

  • was 是 be 動詞
  • looked 是一般動詞（look = 看起來）

所以不能用 wasn't he。

四個選項分析

(A) did he ❌
前面是肯定句，後面不能再用肯定。

(B) was he ❌
looked 不是 be 動詞。

(C) didn't he ✅

(D) wasn't he ❌
如果原句是 Allen was upset 才對。

你可以記這兩組：

He looked tired, didn't he? ✅

He was tired, wasn't he? ✅
