型态
将来完成式是由两个要素组成：
动词 to have 的一般将来式 (will have) + 主要动词的过去分词
| 主词 | + will have | + 主要动词的过去分词 |
|---|---|---|
| He | will have | finished. |
| I | will have | finished. |
将来完成时，以 to arrive 为例
| 肯定句 | 否定句 | 疑问句 | 否定疑问句 |
|---|---|---|---|
| I will have arrived | I won't have arrived | Will I have arrived? | Won't I have arrived? |
| You will have arrived | You won't have arrived | Will you have arrived? | Won't you have arrived? |
| He will have arrived | He won't have arrived | Will he have arrived? | Won't he have arrived? |
| We will have arrived | We won't have arrived | Will we have arrived? | Won't we have arrived? |
| They will have arrived | They won't have arrived | Will they have arrived? | Won't they have arrived? |
作用
将来完成进行时涉及未来未完成的动作。当使用这个时态时，我们对未来会有所期望，并且反观在未来某时间会完成的动作。大部分常与时间词一起使用。
