В Америке 50 соединенных штатов. Население около 200 миллионов. До 1776 года в Америке было много флагов. В Род-Айленд, например, изображался якорь на флаге, в Массачусетс - дерево, Нью-Гэмпшир - корабль. В 1776 году после оглашения декларации о независимости "Звезды и полоски" впервые появились на Американском флаге. 13 полосок представляют собой 13 штатов, которые подписали декларацию о независимости и белые звезды означают число штатов, входящих в целое число союза. Новые штаты вступали в союз и появлялись на флаге 26 раз. Два самых северных штата, Аляска и  Гаваи.

Thanks for your letter, I was so happy to get it! Glad to hear that you have won the running competition! Congratulations on your first place, Jen!

You are asking me about my plans for the summer holidays. Well, I am going to spend this summer together with my family. We like to travel, so all summer we will spend in different countries. We are going to visit Greece, Italy, Spain, Portugal, France and Germany. I really dream to see the Coliseum. I am fond of ancient Roman history since my childhood. And I consider that it was a great empire which had no equal in all the world.

And what about your summer holidays, Jen? Are you going to go abroad or will you stay home? And when do you have next competition? Send me a picture with your gold medal!

Please give my warm regards to your parents and brother. I often remember my journey to New York and your hospitality. It was great!

Well, got to go now. Looking forward to hearing from you!
