同學們在使用將來完成進行時的時候可能會或多或少地出現疑惑——到底該在什麼時候使用這個時態，接下來，小編就結合例句圖文並茂地告訴你將來完成進行時的一些用法。 用法1：Duration Before Something in the Future我們可以用將來完成進行時來表示一種在某個將來的特定時間或者事件發生之前持續進行的狀態。比如說：for five minutes, for two weeks 或者是 since Friday，類似這樣的時間狀語都常被用於將來完成進行時中。請注意，這些時間狀語也會出現在現在完成進行時以及過去完成進行時當中，但是隻有在將來完成進行時中，這些時間狀語將要指向將來的狀態。比如說：They will have been talking for over an hour by the time Thomas arrives.She is going to have been working at that company for three years when it finally closes.James will have been teaching at the university for more than a year by the time he leaves for Asia.How long will you have been studying when you graduate?We are going to have been driving for over three days straight when we get to Anchorage.A: When you finish your English course, will you have been living in New Zealand for over a year? B: No, I will not have been living here that long.
用法2 Cause of Something in the Future
可以在將來某個別的動作發生之前使用將來完成進行時來表示事情的原因或者影響。來看接下來幾個例句：
Jason will be tired when he gets home because he will have been jogging for over an hour.Claudia's English will be perfect when she returns to Germany because she is going to have been studying English in the United States for over two years.
