文字稿

Hi! I’m Tom, and today I’m going to show you how to use the future perfect continuous.

When we use the future perfect continuous, we imagine ourselves at a point in the future. And, we then talk about a continuing action which leads to this point.

Let’s practise.

At the start of the next scene, I will have been eating noodles for five minutes.

See? It’s nearly finished.

We make this tense using subject, will have been, plus verb-ING.

For example: At lunchtime, I will have been working for four hours.

And we can also use ‘won’t’ to make the tense negative.

用法总结

1 将来完成进行时的用法：想像未来的某个时间点，并谈论一直到该时间点仍在持续进行的动作。 

At the start of the next scene, I will have been eating noodles for five minutes.

By this Thursday, he will have been waiting for this parcel for 20 days.

2 将来完成进行时的基本结构：主语 + will have been + 动词-ing。可以把其中的 “will” 改为 “won’t” 来组成将来完成进行时的否定句。 

At lunchtime, I will have been working for four hours.

My colleagues are getting a pay rise next week, but I won’t have been working here for long enough to receive it.
