更新: 請教羅莉知識長,

know 和die 好像也可歸類於"瞬間動詞" , 那題目怎麼改, 這2個動詞就不能用完成式啊?
更新 2: 再請教羅莉知識長,

您說"昏迷不可能恰好發生在救護車到達的同一瞬間,...", 那如果昏迷就是發生在那一瞬間呢, 句子該怎麼寫啊?
更新 3: 羅莉知識長,

謝謝您的耐心回答. 只剩最後一問了. 您的句子:
No sooner did the ambulance arrive than the injured man got fainted from bleeding.
如果改寫如下也OK嗎?
No sooner had the ambulance arrived than the injured man got fainted from bleeding.

另外也謝謝您幫我把跟本題不相關的他人張貼內容隱藏起來, 您可以把它刪掉嗎?
