Question

英语中的THE到底是怎么用?
比如这三个例句：1、when do you get to the library?2、we must get to school early today.
3、what's for lunch?
为什么第二个例句和第三个例句的school和lunch前都没有加the,我感觉这两个名词也应该特指呀.
请不要复制长篇the的用法,那些我在语法书上都看过,只是在实际中遇到这些例句时总是想不明白.

Answer 1

the 可以表示特指,可以指代this/that /these/those.如1.
2.有些词是否加the意义不同:
   go to school上学；go to the school去那所学校,不一定去上学.
 get to school到学校上学；get to the school到达那所学校
go to church做礼拜；go to the  church去那所教堂
3.一日三餐的名词前不加the,但若有形容词,则要加a/an.

      for lunch,have dinner,have a big supper
  但若是特指,还是要加the:
  The lunch we had yesterday was very delicious.
