Visual guide
Identity/class frame: X = Y She = a doctor person = class/role Meaning: X belongs to Y
Same link, different marking: [She] [is] [a doctor] [She] [doctor] zero BE [She] [doctor-CASE] Marking changes; X = Y stays.
Разбор по языкам
В родном языке
Identity uses zero copula in the present; past/future often use быть.
Она врач.
She doctor.
На изучаемом языке
Для идентичности и классификации английский обычно использует be. Перед исчисляемым существительным в единственном числе часто нужен артикль: a doctor.
She is a doctor.
is a doctor = классификация: «она — врач»
Учащиеся могут сказать She doctor или She is doctor, пропуская be или артикль a.
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
