How To Study English

At my new working place in Yokosuka city, I hear that I have to use English in common because foreign researchers often come there. I have learned foreign languages when I was a university student but have to learn again.
I googled how to learn English, found three methods: “iKnow”, “Duolingo” and “Sandwich method”. They cost 10,000 order yen so I start to write blog articles in English language and read English website as much as I can.
I had a hobby to read dictionaries for long days so I have Chinese, Germany, French, Russian and Greek dictionaries. As the web times, I can search any information using them, also publish any sentences at own media.
Fortunately I usually publish my daily diary on here, I use English to improve my English skill especially for sudden use. I could remark this article without any dictionary, but look up natural words and collocations on the web from now on.
