Australia I watched a TV show about Purnululu National Park of Australia this evening. I had lived in Austraia for a year when I was 22 years old. I travelled many places as possible as I could. I went to Melbourne, Tasmania,Cairns, Uluru-Kata Tjuta National Park, Perth....etc. I pulled a guide book after a long time. I looked back on that time. I hope I visit to host families one day. So I should study English harder. But I don't know how to study English...
