1) Dear Clare,
2) Thanks for your email. 3) I was glad to hear you. Sorry, I haven't written to you earlier but I was busy preparing for my exams.
4) I'll be happy to answer your questions. As for me, I love TV as well and I usually watch it in the evening after doing my homework. I really like watching programmes about history because I like learning about the past. If I had a chance, I would love to go on a game show because I think it would be fantastic to win a prize! Everyone in the country would see me do it!
5) I have to go now, I have a lot of homework to do.
6) Write back soon.
Best wishes,
7) With love,
Anton
