Study English

I hate studying all subjects except English. We can communicate in English as a common language. I  was so impressed when I could communicate in English with people from different countries, even by a bit of gesture... and I had some strange feelings at the same time.. I don't know how to express the feelings though. When I was staying in NewZealand to study English, I was pretty surprised because many younger people were speaking English ,making some jokes and making native speakers laugh. and I felt so embarrassed  when I came back to Japan because many Japanese can't speak English and they don't even try to learn hard. I want to study harder.
