I got a good idea to enhance my English and Russian language level.
To stop use japanese language is very important to improve my english level.
So now I start to write my blog in English.
Sorry if some reader can not understand english.
Also sorry my english is terrible.
Principally I will not use dictionary for writing this blog, so you can find many mistakes on English.
I will try to write understandable english as much as possible.
I notiecd that my ability is not so good to swich languages.
At my room I use my brain for Japanese, while at class room I have to use my brain for English or Russian.
It is impossible for me to change my language mode.
So I use only English or Russian from now.
