Preface - just like a preface of a book ^^

English has become the international language which is used throughout the world, all of us know that [for sure]
Many sites designed for learners of English have come into being, which helps enhance the ability to use English of many many people. Also in the same rush, this site appears on the Internet, serving the same purpose: to help English learners.
I do hope that you can find this site useful for your learning [also teaching, if you are teachers ^^]
