[文法] 時間副詞的just before 用法

[anoymouse (沒有暱稱)]

使用書籍:AZAR English Grammer 3rd edition

在看時間副詞那章節的題目:
We were sitting down to eat. Someone knocked on the door at that momment.

選擇下列適當的時間用詞使兩句變成時間副詞
(a)just as  (b)just after  (c)just before

(a) Someone knocked on the door just as we were sitting down to eat.

(b) Just after we sat down to eat, someone knocked on the door.

(c) 不適合

想請問(b)是不是因為after所以有清楚的時間先後關係,而不能使用Just after
we were sitting down?

那(c)為什麼不行用Just before someone knocked on the door,we sat down to
eat dinner?


謝謝

推 jtmh: 敲門時間點是 were sitting down，而不是之前或之後的點
→ anoymouse: 那(b)為什麼不能用過去進行式?
推 b9910: 這不是考時間..  關鍵是sit down的含意你要了解
→ b9910: 坐下來(sit down)是沒有持續性的動作
→ b9910: 原句的We were sitting down...不是進行式
→ b9910: 那是用來表示"即將或很快就要"發生的動作
→ b9910: 原句的中譯應該是 我們正要坐下來時 有人敲門
→ b9910: (b)要改成 just before就合原意了
→ dunchee: "想請問(b)...先後關係,...?" -> 基本上是如此。有空我再
→ dunchee: 繼續
→ dunchee: 我回在  goo.gl/n5nSnT
→ anoymouse: 我先看看吧 謝謝  有問題在私信問你好嗎
