1. We use "will" to talk about things we believe will happen in the future. It's often used for promises or decisions made at the moment of speaking.
- Example: "I will go to the park tomorrow."
2. We use "going to" to talk about plans or intentions we have already decided on before now. It's also used when we see something that is about to happen.
Structure: "Going to" is used with a form of "to be" (am, is, are) + "going to" + the base form of the verb.
- Example: "I am going to visit my grandma this weekend."
3. We use the future continuous tense to talk about actions that will be happening at a specific time in the future.
Structure: will be + verb ending in -ing.
- Example: "I will be playing soccer at 3 PM."
Remember to use "will" for quick decisions or promises, "going to" for plans, and future continuous for ongoing actions at a future time.
