English talks about the future using several different forms, and the choice depends on meaning, evidence, planning, and how near or certain the future feels. The most common future forms are will, be going to, the present continuous, the present simple, and future continuous. This module explains when to choose each form so you can express predictions, plans, schedules, and ongoing future actions clearly.

Use will to express a neutral future statement, especially when the decision is made at the moment of speaking or when you are not emphasizing a plan. Will is common for predictions that are not based on visible evidence right now and for formal or general statements about the future. Will also appears naturally in quick responses and short replies.

Use will for a prediction without present evidence	🧩 对没有当前证据的预测使用 will	I think it will rain later.	🗣️ 我想待会儿可能会下雨。

Will is also used to show willingness, offers, promises, and requests. These uses focus less on time and more on attitude or intention. In these meanings, will often sounds more natural than be going to.

To choose a future form, decide whether you are expressing a schedule, an arrangement, a plan, an on-the-spot decision, a prediction, or an action in progress. Present simple is for timetables, present continuous for arranged plans, be going to for intentions and evidence-based predictions, and will for neutral predictions and quick decisions. Future continuous and future perfect add extra meaning about progress or completion at a future time.
