In my country, students while learning English language are taught that all written sentences can be categorized into certain five types, which are...
1st. Subject + Verb--I am running.
2nd. Subject + Verb + Subject Complement--I feel good.
3rd. Subject + Verb + Object--I made a pie.
4th. Subject + Verb + Indirect Object + Direct Object--I got him a present
5th. Subject + Verb + Object + Object Complement--I helped him hide.
,and that sentences, which do not fit in any of these types seemingly, have their elements reduced or inverted. For example, an imperative sentence "Stop" is actually "You, stop;" as for interrogative sentences, they are regarded as are having their subject and verb inverted. Students are highly recommended--or arguably forced--to memorize these types in order that they be better at understanding structures of sentences.
I heard that countries using this kind of method are only Korea and Japan. So I've got some questions: Does any of you have any clue about how this method has become adopted? I mean, was there any scholar who insisted this? And is there another country that teaches the same thing?
