Compared to Chinese materials, it is much easier to come across good English materials everyday. You can wake up every morning and buy an English newspaper for good content. If the local writers don’t write well, turn to international and sport sections for contents written by international writers.
Nurture your interest in sports and international affairs so that you can read articles and analysis reports written by foreign writers. Whatever topic they write, it is not easy to come across grammatically wrong sentences. And they usually maintain a tone of voice of professionalism and self-respect.
With such reading input, your can also produce writings of dignity and self-respect.
