多くの人がおかす同じ間違い I noticed that many people who study Japanese often have same mistakes. For example, "I study Japanese" can be translated to 私は日本語を勉強しています。"しています" is better than "します". "します" means the future, so it becomes "I am going to/will study Japanese". But "しています" also has two meanings that are the custom and the present, so "しています" can be translated to "I study Japanese" and/or "I am studying Japanese now". But Japanese people can distinguish which you mean in the situation.
