Story's about Roberto's life

At the age of 19 Roberto was leaving Sorrento High School. That was in 1960. He hasn't been good student, but he has been very gifted. He always made mistakes, cheated and played truant.One's day tutor said him: ' Roberto you can't be lazy, when you failed your final exams you will be unemployed or you will have badly paid or demanding job a like miner or a factory worker.' Roberto has began made progress and has done one's best. He has leaved school and started work as a plumber. He has met a beautiful girl called Loretta. They have got married. Loretta has worked as a babysister but that wasn't satisfying work. Then she has been a flight attendant. She has worked there for 35 years. Roberto has worked for Lamborghini since 1970. Now they are pensioners. They have just travelled in France. They have never got childs and they never done a big carrer. Have they ever stopped love? No, they have never stopped becuse they haven't need money for love.

'Story's' (dlaczego story's- tutaj apost jest niepotr - nie rozumiem dlaczego myslales ze trzeba to uzywac) about Roberto's life

At the age of 19 Roberto 'was leaving' LEFT (bo przeciez nie jest w trakcje odchodzenia ale juz odszedl/skonczyl) Sorrento High School.
He 'hasn't' WASN'T 'been' (niepotr) A good student, but he 'has been' (a teraz juz nie jest? WAS) very gifted.
'One's' (nie rozumiem dlaczego znowu ten apostrof- co to daje? tutaj zwykly ONE) day THE tutor said TO him: 'Roberto you 'can't' (nie, bo on 'moze byc' ale 'niepowinnien' SHOULDN'T be lazy, 'when' IF you 'failed' FAIL your final exams you will be unemployed or you will have A badly paid or A demanding job 'a' (co to 'a' tutaj robi?) like A miner or a factory worker.' Roberto 'has' (niepotr) began TO 'made' MAKE progress and 'has' HAD (bo to bylo juz w przeszlosci) done 'one's' (znowu z tym 'one' propsze tego nie uzywac, zanim dokladnie dowiesdz sie gdzie i jak to sie uzywa - wystarczy HIS) best. He 'has' (niepotr) 'leaved' (to slowo niestnieje w tym sensie tutaj LEFT) school and started TO work as a plumber.
He 'has' (nie rozumiem co z tym ;'has' - zachochales sie w tym slowie?) met a beautiful girl called Loretta. They 'have' (niepotr) got married.
Loretta 'has' (niepotr) worked as a babysister but that wasn't satisfying work.
Then she 'has been' WAS a flight attendant. She has worked there (ale gdzie- nie napisales - tutaj trzeba dodac) for 35 years.
They 'have never got' DIDN'T HAVE ANY 'childs' (gdzie to slowo znalazles jako niby ma to byc l. mnoga of 'child' prosze poszukac i napisac poprawnie) and they never 'done a big' (co to ma znaczyc- za kolokw) 'carrer' (ortog). Have they ever stopped love? (czy oni zatrzymali milosc? - cos tu nie tak z tym zdaniem)
No, they have never stopped 'becuse' (napisz to slowo poprawnie) they haven't needED money for love.
