定义 / 说明
英语有不止一种将来表达，选择依据是意义，不只是时间。will 常表示说话当下决定、承诺或一般预测；be going to 常表示已有意图/计划，或基于明显证据的预测；present continuous 常表示已安排好的将来事件。B1 的关键不在“会造结构”，而在“能选对结构”。
关键规则
- 用 will 表示临时决定：I'll answer the door.
- will 也用于承诺和观点预测：I think it will be fine.
- 用 be going to 表示意图和计划：I'm going to apply for that job.
- 用 be going to 表示有迹象的预测：Look at those clouds. It's going to rain.
- 用 present continuous 表示已安排的将来：I'm meeting Sam at 8.
