“将来进行时与将来完成时” （Future Continuous & Future Perfect）
🔒 登录后可标记已读- 将来某个时间点，动作是「正在进行」还是「已经做完」——这个区别就是将来进行时和将来完成时的分界线。
- 将来进行时（will/won't be + -ing）说将来某时间点正在做的事，也能用来说临时/不同以往的新安排。
- 将来完成时（will/won't have + pp）说在将来某时间点之前已经完成的动作，常搭配 by、by the time、in...time 等时间词。
- 想强调持续到将来某时间点还没停的动作，要换成 future perfect continuous（will have been + -ing）。
- 比基本的 will/going to 更进阶，需要理清时间轴上的位置关系，属于 B2 范围。

常见错误
❌ I will be finish the project by Monday. ✅ I will have finished the project by Monday.
📌 说「在某时间点前完成」用将来完成时（will have + pp），不是 will be + adjective。
❌ By next year, I will be study for 3 years. ✅ By next year, I will have been studying for 3 years.
📌 强调持续到将来某时间点的动作，用 future perfect continuous（will have been + -ing）。
❌ 混淆进行时和完成时
💡 判断：动作在将来某时间还没结束、还在进行 → 将来进行时；动作在将来某时间点之前已经结束 → 将来完成时。
