英语中的未来表达不是单一的时态，而是一个概念的 区段。选择正确的形式（Will, Be Going To, Present Continuous）取决于你对事件的 确定性程度、是否事先 计划 以及预测的依据。 The future in English is not a single tense but a conceptual zone. Selecting the correct future expression depends fundamentally on the speaker's attitude regarding the event: the degree of certainty, whether it is a prior plan, or a prediction based on evidence.
简单将来时使用 will 主要用于两种情况：1. 在说话的瞬间做出的决定（自发决定）。例如："I will help you with that bag." 2. 缺乏当前实际证据的纯粹预测或观点。例如："I think it will rain tomorrow."
The simple future tense using will is primarily used for two situations: 1. Decisions made at the moment of speaking (spontaneous decisions). Example: "I will help you with that bag." 2. Pure predictions or opinions about the future that lack current, tangible evidence. Example: "I think it will rain tomorrow."
Be going to 侧重于意图和证据。当我们有在说话之前就已经形成的预先计划或意图时使用。例如："She saved money, so she is going to start university next year." 它也用于基于当前有力证据的预测。例如："Look at those dark clouds; it is going to storm."
Be going to focuses on intention and evidence. We use it when we have a prior plan or intention already formed before the time of speaking. Example: "She saved money, so she is going to start university next year." It is also used for predictions based on strong current evidence. Example: "Look at those dark clouds; it is going to storm."
当谈论一个涉及他人的明确、固定安排或既定的时间表时，使用现在进行时。这表达了高度的确定性——该行动几乎可以保证发生。例如："They are flying to London next Tuesday." 这常用于旅行、会议和预定活动。
When talking about a definite, fixed arrangement that involves other people or an established schedule, the Present Continuous is used. This conveys a very high degree of certainty—the action is almost guaranteed. Example: "They are flying to London next Tuesday." This is common for travel, meetings, and scheduled events.
