The document discusses Rule #1 for learning English - to always study phrases rather than individual words. Studying phrases provides context that helps the brain remember words better. It also allows learning grammar unconsciously as phrases demonstrate correct usage. Examples show how phrases like "he was a bad dog" teach articles and verbs, and full sentences provide situational context for remembering difficult words and phrases like phrasal verbs. The conclusion reiterates that students should write down the phrase and context when encountering new words to best learn vocabulary and grammar.
