It was three o'clock in the morning and Tony was asleep in his bed at home when suddenly he heard noises.He got up and went sleepily to the window. He saw black smoke everywhere. The house was on fire!
He ran quickly downstairs, but he couldn't get out because there was fire all around. Tony immediately rushed back upstairs and closed the door tightly behind him. He opened the window. "Help!"he shouted desperately. He was very scared and didn't know what to do because the firefighters couldn't hear him.
Then, he saw a ladder near the window, so he climbed carefully onto it." Don't panic!" a firefighter called up to him ."I'll help you!" The firefighter held the ladder and Tony climbed nervously down.
When Tony was finally safe on the ground, he felt shocked but happy. After all, he was very lucky to be alive.

эм...там точно he climbed carefully onto it?

Why asking?
There is no mistake. Everything is correct.
