因为我上日语教育课程以前，今天收到了从gacco 一个电子邮件。 gacco 是日本MOOC(Massive Open Online Courses)。
As I took a Japanese education course in the past, I have received an email from gacco today. Gacco is a Japanese MOOC.
There is an interesting course in the email, which is Shirakawa Characters Study course.
Professor Shirakawa is very famous for his Chinese characters study.
I have enrolled in this course and am happy to study it.
