[正] The vacation begins tomorrow.
注:中文的“從”字在這種場合是不需譯出的,其他場合也不需譯成 from,例如“新學期從四月開始”。The new term begins in April. “新學期從四月五日開始。” The new term begins on the 5th of April. “茶會從六點開始。”The tea party begins at six o\'clock. “教育從一個人出生開始。” Education begins with a man\'s birth. 例句中的 tomorrow,是一個副詞,副詞前是不可以用介詞的。April, the 5th, six o\'clock, birth 都是名詞。
