Anyway,we talked about Japan and Australia. I was happy to hear that they had great times in Japan. Sometimes, we corrected their Japanese mistakes as they do our English mistakes. They understand our felling and difficulties of studying language. Speaking of our English...
We use many words after looking up dictionaries. It is a common way among learner. But, in daily conversation, we seem to speak unusual words. For example, when we want to say "慣れる" in English, we had used "be accustomed to~" since they pointed out. They told us that native speakers spoke "get used to~" usually. I thought it was one of weak points of Japanese learners who has studied language at a desk. As Mr. Makimoto who helps us to come here in Japan said to me, "CUSTOM MAKES ALL THINGS EASY", which may be the best way to be a good speaker.
