I like Dagmar's suggestion, with only a few corrections of course:

It is a story that I want to translate from Persian to English. Please correct my mistakes. (or: Any corrections are welcome.)

There It was Christmas and the weather was cold and snowy.

شب کریسمس بود و هوا، سرد و برفی

Boy while nude foots exchanged on snow unless/untile maybe cold of snow less make terrible his, his face was sewed on cold glass of story and looked in to story.

The boy with bare feet treaded the snow so that maybe the cold snow felt less terrible. (This is a very awesome English sentence but not very logical.) Only he can tell us for sure, but perhaps he means: The boy with bare feet treaded the snow until he could bear it no longer/to the point where it felt unbearable. His face sticked to the cold window of a store/shop and he looked inside.

In his look waved somthing ,such as with his look, he asked wich every thing he hasn't , such as with his eyes did wish.

There was something about his eyes that begged for all he could ever dream of. 

پسرک، در حالی‌که پاهای برهنه‌اش را روی برف جابه‌جا می‌کرد تا شاید سرمای برف‌های کف پیاده‌رو کم‌تر آزارش بدهد، صورتش را چسبانده بود به شیشه سرد فروشگاه و به داخل نگاه می‌کرد .

در نگاهش چیزی موج می‌زد، انگاری که با نگاهش ، نداشته‌هاش رو از خدا طلب می‌کرد، انگاری با چشم‌هاش آرزو می‌کرد .

new story part1

It is a story that I want translated from Persian to English. Please correct my mistakes! :D

It was Christmas and the weather was cold and snowy.

شب کریسمس بود و هوا، سرد و برفی .
While the boy's bare feet crossed the snow until maybe the cold snow made his trip terrible. His face was sewed (?) on cold glass of story and looked in to story. (story like a book? reading a book?)

In his gaze somthing stirred. Such as with his look, he asked which everything he hasn't... Such as with his eyes did wish. 

Is this one a poem? It's pretty but a little tough to follow.
