GRAMMAR POINTS TO REMEMBER
- Subjective Predictions & Reviews: When writing reviews, recommending things, or making guesses about how someone else will feel, you must use “Will” (or “Won’t”). You are predicting their reaction based on your personal experience, not on physical, current evidence.
- Keywords of Belief: Always look for phrases that signal an opinion or a personal guarantee: “I think,” “I don’t think,” “I am sure,” “I bet,” “I promise,” “I guarantee,” or “Trust me.” These phrases naturally pair with “Will”.
- The “Be going to” Trap: Do not use “be going to” to express your opinion about a movie’s future impact on someone. “Be going to” sounds too factual and requires visual evidence right now (e.g., looking at someone crying and saying “She is going to need a tissue”).
- The Structure Rule: The modal verb “Will” must be followed by a bare infinitive (the pure base form of the verb). Never write “will to + verb”, “will + verb-s”, or “will + verb-ing”.
