Students enrolling in American universities have access to thousands of private and public institutions from the Atlantic to the Pacific. While public universities like the University of Wisconsin and UC-Berkeley receive state and federal aid, students need to pay tuition and fees for public education. Private colleges like Harvard, Yale and Stanford charge higher tuition rates to account for the absence of public funding.By contrast, European universities are largely public and require low tuition payments from students. The reason why public universities are held in higher esteem than private institutions is their commitment to higher education as an inalienable right. While some universities are funded through income taxes, schools in France and Germany have adopted student fees in the last five years to account for budget shortfalls.

Dear Mary, thank you for your letter. I was very glad to receive it.
 In my letter I want to talk about my winter holidays.This winter I spent much time with my family.
Winter is my favourite season. Together with my family we always make a snowman and  throw snowballs at each other. As for skiing, I usually do it with my father. 
And the most important reason why I love winter holidays is the celebration of Christmas and New Year. These holidays are my favourite.
This winter I've visited London. It was my dream to be there! London is the most beautiful city of England. I met the Christmas and New Year there.
It was magical! The whole city was decorated with Christmas trees, lights and ornaments. 
 At night we waited salute in honor of the arrival of the New Year. It was the best fireworks I've ever seen!  The feeling I had was like a fairy tale!
I liked my winter holidays very much. I'll bring you gifts that I bought in London when I'll back home.
With Love, Dasha.
