Where can I find study materials?

[Masao619]

thank you for your 3rd email.that's very kind of you.

sorry for being late to introduce myself.
as they were written in your mail,those tests may teach the differeces between interesting and interested in and also listen and hear and so on,but these are too easy for me.i've already studied such very basic grammer.although i'm in japan where people generally feel quite difficult to find opportunities to use practical english,i have studied english for more than 10 years.although we learners have to have a fresh mind and a humility to study second language,but it's important to study material that is suitable for me.if you have,could you kindly give me some advice in this regard?
