这里 same 之前为何不用 the?

有人问:下面对话中 same 之前不用 the 对吗:

(1)— Happy new year!

— Same to you.

对的,在口语或套语中, same 之前常可省去定冠词 the ,再如:

(2)— I'm just waiting until I move to the country.

— Same with me.

(3)— Does he love you?

— Who knows?

— Do you love him?

— Same answer. Who knows?

在英语口语中,一句中的首词定冠词 the 常可省略,再如:

(4)Time is up.

(5)Line is busy.

(6)Class is dismissed.

不定冠词 a 位于句首时,也常被省去,如:

(7)Good idea!

(8)Stranger to me.
