VOA一分鐘英語：將來完成進(jìn)行時(shí) 用法是什么？

“到這期視頻的第二幕時(shí)，主持人 Tom 將已連著吃了五分鐘的面條。” 如果想用英語來描述前面這句話，應(yīng)使用表示動(dòng)作持續(xù)到將來某個(gè)時(shí)間點(diǎn)的將來完成進(jìn)行時(shí)（future perfect continuous tense）。你知道這句話的正確英語說法嗎？怎樣把這個(gè)時(shí)態(tài)中的肯定句變成否定句？
 
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.
