This is not a piece of advice to you I'm talking to myself for my practice of writing skills. you have naturally known this news,haven't you? considering the progress of smart-phone's function and the policy of The Ministry of Education in direction of use of Digital textbooks. I suppose human's brain shouldn't be used for memory storage. it'd be sufficient for such stuff to depend on digital tools. I suppose language learning need process of man to man education especially of pronunciation. pronunciation skills can't be mastered by oneself. I'm sure that once pronunciation skills had been mastered everyone can proceed learning with confidence.
