文章是NYT的European Central Bank Takes a Radical Step (6月5號)
Mr. Draghi said the moves adopted Thursday had the backing of the entire
governing council of the central bank, who voted earlier in the day — which
he called “an extraordinary degree of unanimity.”
想要請問Mr. Draghi said the moves adopted Thursday had the backing
Thursday 為什麼沒有前面加on
有時候在看小說的時間也會看到省略時間、星期前面的介係詞
(特別是形容詞子句中的情況)
想請問什麼情況下才會這樣省略?是符合文法的嗎?
