Есть ли разница между of и s в языке? то есть будет ли ошибкой если вместо s поставить of ? я имею в виду принадлежание предмета.

Есть. Окончания ‘s добавляется в притяжательном падеже когда речь идет о одушевлённые существительных, а для неодушевленных – используется предлога of.
Однако есть исключения, когда неодушевленные существительные можно поставить в притяжательный потеж с окончания 's:

- Существительные, обозначающие время и расстояние, например today's news.

- Названия стран и городов, например London's streets

- Слова nation, country, city, town: country’s traditions

- Слова ship, car, boat, например car's window

- Слова nature, water, ocean, например nature’s beauty

- Названия месяцев и времени года, например summer's days

- Названия планет: Saturn’s rings

Nowadays a lot of teenagers have problems with their parents.Adults think,that we are silly,selfish and greedy...
It seems to me,that things are far different from their opinions.
Being a teenager is one of the most pleasant periods in lifetime.We trying to understand who we are...That’s why we all need our parent protection and care.Many teenagers want to look older and mature.As a result,they start smoking and drinking alcohol.Many of us can’t understand how unhealthy it can be.We often meet our first love.But this type of love can be unhappy.Parents should try to keep their beloved child busy.Today we can find something useful to do,have an interesting hobby.Consequently,these teenagers are less seen in bad companies.
Also,we should think about passing our exams successfully.
To sum up,everything depends on individual story and conditions...As for me,I would try to listen to my parents,because I like them so much!
