그러자 노인이 게으름뱅이에게 쇠가죽을 둘러씌웠어요.
And then he was forced to wear cow\'s leather by old person.

게으름뱅이는 깜짝 놀라 탈을 벗으려 했지만 때는 이미 늦었어요.
he was surprised. Although he tried to take mask off, it was late for that

노인은 소를 끌고 가 어떤 농부에게 팔았어요.
the old person sold a cow to peasant walking down the road.( o/x ) 
the old person sold a cow to peasant when he was walking dwon the road.( o/x )
(이 둘중에서는 어느게 맞나요? 둘다 맞는 표현이에요? )

게으름뱅이는 끌려가지 않으려고 버티며 소리쳤어요.
The man shouted because of not being drawn.

그러자 사람들은 웬 소가 저렇게 울어대나 하고 생각할 뿐이었어요.
but, the people thought why a cow cried.

그 동안 너무 게으름을 피워 벌을 받은 거라고 생각하니 지난날이 몹시 후회 스러웠어요.
he regretted doing nothing in the past because he was punished by that.
