Почему так: a ставим перед исчисляемым существительным в единственном числе при первом упоминании (book, school, classroom, desk). The используем, когда предмет уже упоминался или понятен из ситуации (the table/park/school/classroom/desk/book). Во множественном числе для неопределённого количества ставим some (books, pictures, pens).
