Sprawdzenie wstępu do rozprawaki

When a child does not want to do his homework, eat, learn, help his parents in daily activities, is oppose to go sleep in the required time, destroys his toys, becomes to be arrogant, rude or just something else then parents look for a proper source to encourage children to do something. Usually that source turns out to be a prize or punishment. In this essay I will try to prove which way of bringing up children seems to be a better one. According to many adults punishing is the best method because it improves a child behavior. But in my opinion it has its good and bad sides. First of all I would like to consider in which way we apply the punishment. Most of the parents have a tendency to using physical violence when they are annoyed at something.

When a child does not want to do his homework, eat, learn, help his
parents in daily activities, is opposeD to goING TO sleep 'in' AT the required
time, destroys his toys, becomes 'to be' (niepotr) arrogant, rude or 'just
something else' (jak dziecko moze byc 'something else'?) then parents MUST look for a 'proper source' (cos nie tak- napisz 'a way') IN ORDER to encourage children to do something.
(To zdanie jest za dlugie)
Usually that 'source' (cos tego nie lubie, zle pojecie, tutaj mozesz napisac..that something..) turns out to be a prize or punishment.
In this essay I will try to 'prove' (nie, nie tak, 'prove' jest za silne slowo, lepiej 'illustrate') which way of bringing up children seems to be 'a' THE better one.
According to many adults punishing (kogo? czego?) is the best method because it improves a child'S 'behavior' (behaviour - BrE).
First of all I would like to consider THE WAY in which 'way' (niepotr) we apply the punishment. Most of the parents have a tendency toWARDS using physical violence when they are annoyed at something OR SOMEBODY.
