from then on含義與from now on from then on含義相同,但是時態不同。 from then on指的是過去發生的事情或時間, from then on發生了什麼,或者直到現在發生了什麼。 from now on代表當前時態,意味著將來將繼續這樣做。例子: I ordered the beef noodles but I think I like the chicken noodles better. From now on, I'll only order the chicken. (我點了牛肉麵,但我認為雞肉麵更好。從現在開始,我只點雞肉麵。)例如: When he was five years old he was bitten by a dog. From then on, he has a little bit afraid of dogs. (他五歲時就被狗咬了。從那以後,他有點怕狗了。)
