[文法] 選擇題

[fish213 (黃小新)]

The report on the nuclear power plant indicated that when the plant had

gone on line ______ unsafe.


A. it had been

B. had been


答案是 A，我的問題是 "when the plant had gone on line" 似乎可以當成

名詞子句，當成主詞用，所以 it 看來是多餘的？請問這個想法錯在哪邊呢？

謝謝 ^^"

推 Chiwaku:when 片語當條件副詞用
推 fish213:請問這邊 when 不可以當名詞子句用嗎?? @@
→ fish213:when當副詞用的話，it前面需要加 "," 嗎?? @@
推 Chiwaku:不需要　我好像沒看過when片語當名詞用
推 fish213:感謝您~ 因為我在看朗文托福聖經，裡面有一條例句
→ fish213:When the season starts is determined by the weather.
→ fish213:所以才會覺得有當做名詞的可能，不過如你所說，當做副詞來
→ fish213:看的確是選A，快亂了 @@
推 Chiwaku:看了你的例句恍然大悟，但此時的when有名確的時間意涵
→ Chiwaku:明確
推 EDRTFG:when 前面省略了the time 所以可當主詞
