C pas du grand anglais mais je te corrige un peu ce que tu as ecrit :
I advise you to go in Alaska because it ´s not an ordinary country. There is a lot of white mountains which are beautiful. The biggest vegetable is growing there. In Alaska the summer lasts eighty two days and the longest night lasts sixty seven days. There is Also the beautiful polar bears who are very dangerous. In this country we can do a lot of activities like dog sledding and fishing.
