I have 2 questions regarding adding “the” before the noun in correlative comparative structure.
A teacher advised me to put “the” before the noun in correlative comparative, but after practicing some tasks I’ve discovered that it works only for STRUCTURE (A) and it sounds less natural for STRUCTURE (B). I want to confirm whether I should use “the” only for STRUCTURE (A)?
Does adding “the” to the STRUCTURE (A) depend on the situation or it is a must to ensure that the sentence is grammatically correct?
I would be thankful if in case it depends on the situation that you give me an example without "the".
STRUCTURE A: The more + adjective + noun + …
(1) The higher (the) level you reach, the easier it is to speak English.
(2) The longer (the) hours you work out, the stronger you become.
(3) The hotter (the) weather is, the more you sweat.
(4) The smaller (the) car is, the less petrol it uses.
(5) The more you earn, the more expensive (the) things you buy.
(6) The fewer (the) students, the more I like the lessons.
(7) The older (the) people, the wiser they become.
STRUCTURE B: The more + noun + …
(A) The more (the) fruits you eat, the more (the) vitamins you get.
(B) The earlier* you leave for work, the more (the) tasks you complete.
(C) The more you study, the less (the) time you have for friends.
(D) The more (the) rules we know, the more correctly we write our tests.
Thank you for the time you'll take to read and to answer my question.
