Нужно написать письмо американскому другу с приглашением пожить у меня в гостях,рассказать о своей квартире и хобби! 

Hey, Bob! How are you doing? Where are going to spend a winter vacation? I have a great idea. Parents are allowed to invite you to visit. Can spend the holidays together. Parents will also be very pleased.We have a very large house. We will allocate a separate room for you. We're going to ski, skate. By the way, I have prepared a surprise for you. I'll wait impatiently your arrival.
