Complete Alex's letter with the correct form of am/is/are.

Dear Sveta, Thank you for your letter. I am Alex. I **am** from Great Britain. My country **is** beautiful too! The capital of Great Britain **is** London. There **are** many new and old houses and bridges in London. There **are** a lot of cars in the streets. You can also see many interesting towns in GB, like Oxford, Cambridge and others. I live in Oxford. But I often visit my granny. She lives in the country. There **is** a green garden with white, red, yellow and blue flowers next to her house. There **are** green fields and white sheep in the country. I think Russia **is** a beautiful country. So I want to visit Russia next summer. Your pen friend, Alex Giggs
