'The' (niepotr) (nie za dobry start) last 'saturday' (ale przeciez chyba wiesz, ze dni tyg piszemy duzymi literami) in the morning we 'heart' (heart - to znaczy 'serce' nie bardzo rozumiem dlaczego tutaj to napisalas) in the news (brak przedimka) warning about strong tremors which could pose a serious threat to people. We got instruction what security precautions we should 'took' (zly czas - tutaj teraz.) like 'protech' (ortog ale i tak zle slowo) 'yorself' (ortog ale i tak zle slowo) under a table or bed or 'carry' (pomysl co chcesz napisac-zle slowo) a whistle with you.
(brak przedimka) first tremors which 'spell' (zly czas) disaster we felt in 'afternoom' (ortog). This 'last' (zly czas tutaj czas przeszly) less than a minute. Violent shaking, from (tu cos brak)'furnitures' (to jest niepol. dlaczego dodalas 's') were falling 'deferent' (to jest zle slowo) things like dishes, 'windowas' (ortog) were crashing and 'from walls were falling pictures' (zla kol slow). We 'protect' (zly czas tutaj czas przeszly) 'ours' (zle slowo) 'head' (dlaczego dajesz l. poj, jak wczesniej piszesz 'we'?) from 'dangerous' (zla czesc mowy). We 'heart' (znowu to 'serce') screaming people. After (brak przedimka) eathquake we went outside.
When we looked around we 'were seeing' (simple - SAW) crashed cars, 'bursted' (zle slowo) ground and destroyed streets. Trees 'were being' (tutaj zly czas - ma byc przeszly) pulled up by their roots. RockS (daj l. mn bo bylo wiecej jak jeden) fell and blocked the road. We 'rose' (zle slowo) the alarm . On the street lay (tutaj cos brak) injured so we started (brak cos) 'got' (zly czas) help and first aid. (brak przedimka) disaster area was 'that' (daj tutaj 'very') huge that there came many 'of' (niepotr) emergency services. They started (brak przedimka) 'rescu' (ortog) operation. Emergency officers evacuated people 'which' (kiedy mowimy o ludziach, to zawsze 'who') were at risk. They 'were' (niepotr) saved many people's 'life' (tutaj ma byc l. mn).
I am 'thanksfull' (ortog) that I survived. 'Well that' (to jest zle, napisz AS THE) early warning system worked that way THERE was less victims.
