Here are 3 golden rules for effective communication: 1. Improve pronunciation and diction by focusing on vowel sounds and consonant articulation, singing songs aloud, watching news programs, and using pronunciation resources. 2. Spruce up writing skills by reading widely from magazines, books on interesting topics, and learning basic grammar rules for emails and attached documents. 3. Practice oral communication daily by pretending to be a newscaster, focusing on national newspapers, looking up unknown words, using them in conversation, and speaking English with friends and family.
