Issues of practising English skills

I urge users of this site to express more views and to learn more on the crucial issue of practising English by learners of English. English teachers also have to be sufficiently knowledgeable in this issue in order to properly teach and guide learners in this process. I believe the debate ought to focus on how learners can practise the following aspects of using and improving English skills: listening comprehension, speaking, reading and writing. In my view, to thoroughly explore this issue, it is important to take into particular consideration aids, methods, activities, exercises and tasks for practising and improving English skills. Certainly, practising English listening comprehension, speaking, reading and writing is based on English phonetics, grammar and vocabulary skills. They must be included in practising English.
