Znowy z tym 'a' i 'the' prosze wstawiac tam gdzie sie nalezy - nie omijac tego, bez tego zdania nie sa gramatyczne!
The fresh air was blowing into their 'sweat' (nie tu cos brakuje) faces when they at least 'get' GOT TO THE 'a' (niepotr) top of the highest mountain. John said: 'It is one of 'my' THE best days in my whole life'. He would never expect that THE facinating and amazing journey was going to change into SOMETHING dangerous and horrible. In the afternoon tents were pitched, sun was shining and travellers had 'a' (niepotr) time to rest. The main character decided to snatch the opportunity and he went TO visit a rock formation located near A stream. Before he made 'it' (tu cos brakuje) he had taken a 'compas' (ortog) with him. When he was going he paid attention to A strange bush with 'colorful' (colourful czy colorful?) flowers.
When the light from THE camera lit a weird creature with disgusting smell and huge crazy eyes (tu cos brakuje) attacked him. It had 'got' (niepotr) an amazing strenght but Tom's 'wisement' (niema takiego slowa - popraw) let him to beat it (ale czym jedna reka? patykiem?) and run away. With A bleeding leg Tom was wandering in THE heavy rain among THE trees in THE dark forest when he reminded himself that he had got a 'compas' (ortog). The experience achieved during scout camp helped him to return to THE tent.
In the morning he told (komu czemu?) about everything 'his friends' (nie w tym miejscu) but they did not believe his story. When he showed them the photo of THE creature they almost faintED and after a while they decided to finish their journey.
